Corvette Horsepower Rating Timeline By Year
Corvette Horsepower Table of Contents:
1953-54 Corvette Horsepower
195 horsepower 265 CI V8
265-cubic-inch V8, Increased to 210 horsepower
Corvette engine grew to 283 cubic inches and 220 horsepower, breathing through a single four-barrel carburetor.
The 283 could be had with dual-quad carbs rated at either 245 or 270 horsepower or, best of all, with Rochester mechanical fuel injection. The Fuel injection "Fuelie" on top of that 283 increased its output to either 250 or 283 horsepower.
1958-59 Corvette Horsepower
283 small-block base single four-barrel version now making 230 horsepower, dual-quad versions were rated at 245 and 270 horsepower and the fuelie engines now made either 250 or 290 horsepower.<br>
Fuel-injected versions grew to 275 and 315 horsepower.
V8 increased 327 cubic inches. The base four-barrel engine now put out 250 horsepower with higher output versions available in 300-340 horsepower versions. The dual-quad option was dropped, but the fuel injection system was back and it was now rated at 360 horsepower.
1963 Start of the mid year Corvettes
327 V8 was still rated at 250 horsepower. On the options sheet were 300- and 340-horsepower four-barrel, and 360-horsepower fuel-injected versions of the 327.
327 V8 was still at 250 horsepower. Optional 360-horsepower four-barrel 327, and the fuelie motor was now rated at 375 horsepower.
1965 Corvette Horsepower
327 V8 250 horsepower. Optional: The "L78" 396 appeard and made 425 horsepower. As for the fuel-injected 327's— 1965 would be its last year.
396 lasted only one year in the Corvette as it was superseded by 427-cubic-inch. Base 327, now rated at 300 horsepower, a 350-horse version in a single four-barrel, the "L39" 427 making 390 horsepower and the "L72" 427 rated at 425 horsepower.
Base 300-horsepower 327 small-block V8 topped by a four-barrel carburetor. "L88" 427, which used aluminum cylinder heads and 12.5-to-1 compression ratio to make somewhere north of 500 horsepower while wearing a huge 850-cfm four-barrel carburetor (though Chevy would, disingenuously, only admit to 430 horses). The L88 option upon ordering it automatically eliminated the heater, radio and fan shroud. The intent was obviously racing and only 20 L88s were ever built. Today they are the most desirable of the first Sting Rays.
Also new to the Corvette option charts was an "L68" 427 rated at 400 horsepower and the L71 427 rated at 435 horsepower and featuring three two-barrel carburetors ("tri-power").
300-horsepower 327 small-block V8 topped by a four-barrel carburetor. The optional engines included a 350-horsepower 327 and all the big-block 427s from '67 including the awesome 500 horsepower L88."L68" 427 rated at 400 horsepower and the L71 427 rated at 435 horsepower and featuring three two-barrel carburetors ("tri-power").
1969 Corvette Horsepower
Replacement of the 327-cubic-inch small-block V8s with new 350-cubic-inch versions. As with the 327s, the 350s were rated at 300 horsepower in base form and 350 horsepower in the optional "L46." The 427s also returned carrying the same power ratings as '68's. ZL-1 was a limited production option and only two of the 585-horsepower ZL-1s were produced.
Base 350 300 HP. The "LT-1" 350 370-horsepower. Two 454-cubic-inch big-block V8s — a 390-horsepower "LS5" wearing a four-barrel carburetor and a tri-power equipped "LS7" making a claimed 460 horsepower although non where sold.
1971 Corvette Horsepower
Base 350 dropped to 270 horsepower because of emissions. LT-1 350 dropped to 330 horsepower. The detuned LS5 454 now made a mere 365 horsepower. Gone was the LS7 454 and in its place was an "LS6" 454 four-barrel V8 rated at 425 horsepower.
switch from SAE gross to SAE net power ratings. So the base 350 now produced a 200-horsepower rating, the LT1 made just 255 horsepower, and the sole big-block, an LS5 454, could only do 270 horsepower.
1973 Corvette Horsepower
Base 350 now rated at 190 horsepower and a new optional "L-82" 350 made 250 horsepower. The sole 454 was an "LS4" rated at 275 horsepower.
Same HP as 1973 give or take a few ponies. Last year for the big-block V8.
Base 350 V8 making a hideous 165 horsepower or the L82 making 205 horsepower exhaling through a catalytic converter.
The base "L48" 350 was now rated at 180 horsepower as engineers were beginning to figure out the intricacies of emissions regulations. The L82 350 jumped to 210 horsepower. Both engines breathed in through four-barrel carburetors.
Same HP and engines as 1976.
The base L48 350 was now rated at 185 horsepower and a new dual-snorkel intake bumped output of the L82 version to 220 horsepower.
A dual snorkel air cleaner now fed the Base L48 350 and that boosted output to 195 horsepower. The L82 was treated to a new cam, larger valves, a higher-compression ratio and a more efficient exhaust system which all combined to push the engine to 225 horsepower.
Base L48 350 now made 190 horsepower and the L82 was rated at 230. Californians were stuck with only a 305-cubic-inch V8 making 180 horsepower.
A new, 190-horsepower "L81" version of the 350 V8 was the only engine available.
"Cross-Fire Injection." This injection system boosted output of the L81 350 to 200 horsepower.
N/A Since no Corvettes were made.
C4 Corvette Horsepower
1984 Start of the C4
350 V8, again equipped with Cross-Fire throttle body fuel injection and now rated at 205 horsepower.
1985 Corvette Horsepower
Tuned Port Injected (TPI) version of the 350-cubic-inch (now more commonly referred to as a 5.7-liter) small-block for 1985. This vastly more efficient induction system bumped output of the V8 to 230 horsepower.
Same as 1985
Hydraulic roller lifters to the L98's valve train boosted its output to 240 horsepower.
New aluminum cylinder heads and a revised camshaft boosted the L98 to 245 horsepower.
Same as 1988

Same as 1990
1992 Corvette Horsepower
LT5 V8 made 375 horsepower. A new LT1 was rated at 300 horsepower thanks to significant revisions to the cylinder heads, accessory drives, cooling system and fuel injection.
LT1 was 300 horsepower The LT5 horsepower went from 375 to 405 — in real-world terms (accounting for the difference between the old SAE gross and current SAE net rating methods)
Same as 1993
Same as 1994 Last year for ZR1 in the C4.

History of the Corvette Z06 – A Supercar Made for Racing
With the release of the 2016 Chevy CorvetteZ06, which is the fastest Corvette ever produced, I think it’s necessary to give the Z06 some history. It’s not like this Z06 became the fastest Corvette overnight; it took years of tweaking and improving in order for the Corvette to get to where it is today. It all started back in 1963, when the Z06 was introduced as an option package. At this time, it was directed for those who wanted to use the Corvette on the track.
That fact remains true today, but now it’s offered as it’s own model that’s based on the Stingray design. The modern Z06 is still track-oriented, but has evolved to be a vehicle that would love its previous generations in the dust. In honor of the new Z06’s evolution, let’s take a look at the history that it was built upon.
It All Started with Zora
Zora Arkus-Duntov is the legendary Corvette engineer that got the Z06 its start. Since he was also a race enthusiast, he wanted to give the Corvette a package that would allow it to perform competitively on the track. 1963 was the year that he was able to successfully lobby for the Z06 racing package, giving the 1963 Corvette its first taste of racing blood.
Since his introduction of the Z06 package, the Corvette Z06 has been around for 4 out of its 7 generations. With each new generation bringing a fiercer and stronger Z06 to the table.
Second Generation: 1963
The Z06 package came about in the second generation of the already highly-praised Corvette. Duntov made sure that if you selected the Z06 package on the 1963 Corvette, you would get a Corvette that was bred for the track. The first option package offered for the Corvette added a thicker front stabilizer bar, diameter shock absorbers, and springs that were almost twice as stiff than the ones on the standard Vette.
In order to further enhance the handling prowess of the new race-track monster, the Z06 package also included upgraded brake components with sintered-metal brake linings. These brakes resisted wear and tear better than the standard brakes, as well as the heat generated from the harder stopping-power required for a performance car. The Z06 also featured a dual-circuit master cylinder and vacuum brake booster.
These components not only enhanced the safety of the Z06 when on the track, but also helped reduce braking effort.
Bigger Fuel Tank
The Z06 needed to be enhanced in terms of the amount of fuel it could hold. A bigger fuel tank meant that racers could stay on the track longer, not spending as much time tanking-up. The fuel tank was a 36.5-gallon monstrosity, so it’s only natural the Z06 of 1963 got the nickname “big tank” or “tanker.”
This bigger tank was originally too large for the convertible model at the time, and could only be offered on the coupe. Chevy revised the package later on, and this made the 20-gallon fuel tank standard and the big tank optional. The introduction of this new fuel tank was possibly the most significant racing enhancement the Z06 received at the time.
There was only one engine option offered in the Z06 model at the time, and that was the 360 horsepower 327-cubic-inch small block engine. Thanks to Chevy’s knowledge of fuel injection (they introduced it in 1957), this small block 360 horsepower featured an advanced mechanical fuel injection system.
This advanced system was able to deliver fuel to the system in a more precise and quicker manner, allowing the Z06 to be one of the best track cars around.
Fifth Generation: 2001-2004
In 2001, the Z06 was no longer a package; but it’s own model. At this time, the Z06 was reintroduced as a special 2001 model. Much like the 2016 Corvette Z06, the 2001 Z06 was a landmark in Corvette history. The performance was better than ever, and this was thanks to the redesign it received.
The engineers wanted to make sure this new Z06 would be the best performing one yet, so they made sure to provide it with lighter components. A limited hardtop body was introduced, which had a fixed-roof design that was stiffer and lighter than the one on the coupe. It also saw the introduction of thinner glass, lighter wheels, a titanium exhaust system, and even a lighter battery.
The result was a weight-loss of about 100 pounds, which helped create an even faster car when paired with the upgraded engine.
The 2001 Z06’s Gen III small block engine was able to produce a healthy 385 horsepower. Thanks to unique internal parts, like an improved camshaft and higher-compression pistons. In 2002, the Z06’s engine was able to put out 405 horsepower, which was a large amount at the time.
Thanks to the weight loss and improved engines, the 2004 Z06 was able to complete the infamous Nürburgring road course in Germany with a time of just under 8 minutes.
Sixth Generation: 2006-2013
The third installment in the Z06’s legacy was yet another earth-shattering one. The Z06 was now able to compete with the world’s most capable supercars, with a 6:2:1 power-to-weight ratio. This power-to-weight ratio was one of the best ones in the world, and allowed it to attain 0-60 in 3.7 seconds.
This generation also saw the introduction of a first ever aluminum frame, resulting in another 136 pound weight loss. Allowing this generation Corvette to weight in at 3,130 pounds. This aluminum frame is still present in the Z06 today, and has been enhanced even further to make the Vette stronger, lighter, and faster.
The 7.0-liter LS7 small block engine was introduced to this generation of Corvette, which made it (again) the fastest Corvette ever produced during this time. This was thanks to the new lightweight frame that was produced, which worked in tandem with the small-block engine that put out 505 horsepower.
In 2012 it was tested on the Nurburgring track yet again, and was able to complete it in 7 minutes and 22 seconds, already almost a whole minute faster than the previous generation.
Seventh Generation: 2015 and 2016
Now, we have the 2016 Corvette Z06. The supercharged engine on it was first offered in the 2015 model, and it’s the strongest engine yet. The supercharged engine on the 2016 Z06 puts out 650 horsepower with the same amount of pound-feet torque. The 2015 model also saw the introduction of an automatic transmission which carried over to the 2016 model, and actually outperforms the manual transmission. The 2016 Z06 is based on the 2016 Stingray design, but adds a slightly wider frame and tires, making the 2016 Corvette an even more aerodynamic vehicle.
It’s clear to see that since the Z06 was created by Duntov that it’s only gotten better. Each generation of the Corvette got lighter as the horsepower got bigger. This was the key to its success, and is why we now have a supercar monster that’s designed to dominate the track.
Chevrolet Corvette (C6)

The Chevrolet Corvette (C6) is the sixth generation of the Corvette sports car that was produced by Chevrolet division of General Motors for the 2005 to 2013 model years. It is the first Corvette with exposed headlamps since the 1962 model. Production variants include the Z06, ZR1, Grand Sport, and 427 Convertible. Racing variants include the C6.R, an American Le Mans Series GT1 championship and 24 Hours of Le Mans GTE-Pro winner.
Chevrolet Corvette coupé
Chevrolet Corvette convertible
The Corvette C6 featured new bodywork with exposed headlamps, revised suspension geometry, a larger passenger compartment, a larger 5,967 cc (364.1 cu in; 6.0 L) V8 engine and a higher level of refinement. It is 5.1 inches (13 cm) shorter than the C5, but the wheelbase was increased by 1.2 inches (3 cm). It is also one inch (2.5 cm) narrower. The new LS2 engine has a power output of 400 hp (298 kW) at 6,000 rpm and 400 lb⋅ft (542 N⋅m) of torque at 4,400 rpm. Like the C5, the Corvette C6's suspension consisted of independent unequal-length double wishbones with transverse fiberglass mono-leaf springs and optional magnetorheological dampers.
With an automatic transmission, the Corvette achieves 15 mpg‑US (16 L/100 km; 18 mpg‑imp) / 25 mpg‑US (9.4 L/100 km; 30 mpg‑imp) mpg (city/highway) of fuel economy; the manual-transmission model gets 16 mpg‑US (15 L/100 km; 19 mpg‑imp) / 26 mpg‑US (9.0 L/100 km; 31 mpg‑imp) mpg of fuel economy. The Corvette's manual transmission is fitted with Computer Aided Gear Shifting (CAGS), obligating the driver to shift from 1st gear directly to the 4th gear when operating at lower RPM. This boosts the EPA's derived fuel economy thus allowing the buyer to avoid paying the "gas guzzler" tax. GM badges were added to the car in 2006.
Beginning with the 2008 model year, the Corvette received a new engine, the LS3. With displacement increased to 6,162 cc (376.0 cu in; 6.2 L), power was increased to 430 hp (321 kW) at 6,500 rpm and 424 lb⋅ft (575 N⋅m) of torque at 4,600 rpm, or 436 hp (325 kW) and 428 lb⋅ft (580 N⋅m) with the optional vacuum actuated valve exhaust. The previous Tremec T56 transmission on manual Corvettes was replaced with a new version, the TR6060, in the 2008 model year. Manual Corvette models now had improved shift linkage; the automatic model was set up for quicker shifts, and (according to Chevrolet) accelerates from 0 to 60 mph in 4.0 seconds, faster than any other production automatic Corvette model. From 2008 onward, the steering was revised for improved feel and the wheels were updated to a new five-spoke design. The last Corvette C6, a white 427 convertible, was completed on February 28, 2013.
The 7.0 L LS7 V8 engine
The Z06 arrived as a 2006 model in the third quarter of 2005 and is the lightest of all Corvette models. The Z06 was equipped with the largest-displacement small-block engine ever produced, a new 7,011 cc (7.0 L; 427.8 cu in) V8 engine codenamed the LS7. The engine has a power output of 505 hp (512 PS; 377 kW) at 6,300 rpm and 470 lb⋅ft (637 N⋅m) at 4,800 rpm of torque. The LS7 is the most powerful production naturally aspirated engine made by General Motors. In addition to the larger displacement engine, the Corvette Z06 has a dry sump oiling system, and connecting rods made out of titanium alloy. The frame of the Z06 is constructed from aluminum, saving 136 lb (62 kg) over the standard steel frame. Other weight saving measures such as balsa wood/carbon fiber composite floors and a magnesium alloy engine cradle were used. The Z06's body differentiates itself from the standard Corvette with its larger front and rear fenders and an intake inlet scoop on the front bumper. The front fenders are constructed with carbon fiber and the rear fenders contain ducts to aid in cooling the rear brakes. The Z06 weighed 3,130 lb (1,420 kg), giving it a weight to power ratio of 6.2 pounds per horsepower (3.8 kg/kW), allowing it to achieve a fuel economy of 15 mpg‑US (16 L/100 km; 18 mpg‑imp) in the city and 24 mpg‑US (9.8 L/100 km; 29 mpg‑imp) on the highway. The Z06 was the official pace car for both the 2006 Daytona 500 and the Indianapolis 500 race. Car and Driver recorded a 0-60 mph (97 km/h) acceleration time of 3.6 seconds and 1/4 mile in 11.7 seconds at 125 mph (201 km/h) in October 2005. The Z06 contains the following enhancements over the standard C6 Corvette:
- Hand-built LS7 V8 with dry sump oiling system
- Aluminum chassis with fixed roof
- Larger/stiffer anti-sway bars
- Stiffer springs and shocks
- Larger rear spoiler and front splitter
- Transmission cooler
- Unique front fascia with intake inlet
- Wider carbon fiber front and fiberglass rear fenders
- Functional front and rear brake ducts for added brake system cooling
- Unique light weight forged aluminum 18-inch front and 19-inch rear wheels; painted finish standard and chromed finish optional
- Wider 275/35ZR18 tires in the front and wider 325/30ZR19 tires in the rear
- Larger 6-piston front and 4-piston rear calipers, including cross-drilled 355 mm (14.0 in) front rotors and 340 mm (13 in) rear rotors
- Optional 1LZ, 2LZ, and 3LZ trim packages.
For the 2011 model year, the Z06 carbon edition was introduced, which carries over multiple parts from the high performance ZR1 including carbon ceramic brakes, active suspension, and other carbon fiber aerodynamic pieces. Only 500 were planned for production and actual production numbers were much lower, in total only about 250 were made. The 250 were optioned the same but did not have the carbon hood. In 2012 and 2013, these options could be ordered through the Z07 package on the Z06.
The ZR1 is the high performance variant of the Z06 was first reported by several print and online publications, based on rumors that General Motors was developing a production version of the Corvette above the Z06 level under the internal code name Blue Devil (named after CEO Rick Wagoner's alma mater, Duke University). The car was originally rumored to feature a superchargedLS9 engine having a power output of more than 630 hp (639 PS; 470 kW).
The October 12, 2006 issue of AutoWeek published photos by photographer Chris Doane of a C6 Z06 with special auto-manufacturer-issued license plates with a hood bulge, widely thought to confirm the presence of a supercharger on the Blue Devil. Other names attached to the project included Corvette SS, after the late '50 racing car, and Corvette Z07. In February 2007, a worker at a Michigan shipping company posted pictures online of a powertrain development mule that was being shipped to Germany, believed to be part of the Blue Devil program. The car had manufacturer's license plates, carbon-ceramic disc brakes, enlarged fender vents, a hood bulge, and an engine with a positive-displacement supercharger in the valley between the cylinder banks and a water-to-air intercooler atop it. GM began to release details on the Blue Devil project in April 2007. The company confirmed the existence of the project in an interview with Car and Driver on April 13. Engine power levels were confirmed to be between 600 and 700 horsepower (447 and 522 kW), but contrary to prior rumors of a supercharged 6.2 liter engine, the engine was only confirmed to have greater displacement than the 7.0 liter LS7 in the Z06.Motor Trend confirmed the official name for the production version of the Blue Devil, resurrecting the old ZR1 nameplate. The ZR1 had originally been used on developmental cars in 1971, and again as ZR-1 as the top of the line variant of the C4 Corvette. General Motors officially introduced the Corvette ZR1 on December 19, giving a press release and photographs of the car. GM confirmed a supercharged 6.2 L LS9 V8 having a power output of 638 hp (647 PS; 476 kW) at 6,500 rpm and 604 lb⋅ft (819 N⋅m) of torque at 3,800 rpm. A test of the ZR1 on the German autobahn revealed a top speed of 192 mph (309 km/h), although the manufacturer claims the car is engineered to attain speeds up to 205 mph (330 km/h).
Carbon fiber is used on the roof, hood, fenders, front splitter, and rocker moldings; the hood and fenders are painted over, while the roof and splitter are merely covered in a clear-coat, retaining their original black color. A polycarbonate window is placed in the center of the hood, allowing the engine intercooler to be seen from the exterior. The wheels were the largest ever placed on a production Corvette, with both front and rear wheels increasing in size and diameter over the Z06. Carbon-ceramic brakes are included. The brake calipers are painted blue, as are the engine intercooler trim and the ZR1 logo. Magnetic Selective Ride Control was also included on the car, with sensors to automatically adjust stiffness levels based on road conditions and vehicle movement.
The 2010 Grand Sport was unveiled at the 12th annual C5/C6 Corvette Birthday Bash, held at the National Corvette Museum. The Grand Sport replaces the previous Z51 option. The GS or Grand Sport was equipped with the following enhancements:
- Specific manual transmission with different gear ratios
- Larger/stiffer anti-sway bars
- Stiffer springs
- Revised shocks
- Larger Z06 rear spoiler
- Transmission cooler
- Functional front and rear brake ducts for added brake system cooling
- Unique light weight forged aluminum 18-inch front and 19-inch rear wheels (painted finish standard and chromed finish optional)
- Z06 brakes, including cross-drilled 355 mm (14.0 in) front rotors and 340 mm (13 in) rear rotors
- Specific rear axle ratio on automatic transmission equipped models
- Optional 1LT, 2LT, 3LT and 4LT trim packages.
- Wider front and rear fenders with integrated Grand Sport badges
- Wider 275/35ZR18 tires in the front
- Wider 325/30ZR19 tires in the rear
- 6-piston front calipers and 4-piston rear calipers
- Dry-sump oil system (manual transmission coupes only)
- Hand-built LS3 6.2 L V8 (manual transmission coupes only)
- launch control (manual only)
The LS2 was replaced by LS3 from model years 2008–2013.
The LS3 engine in the GS convertible or Grand Sport coupé equipped with an automatic transmission has wet sump instead of dry sump lubrication.
Ron Fellows ALMS GT1 Championship Edition (2007)
The Ron Fellows ALMS GT1 Championship Edition is a special edition of the Corvette Z06 developed to commemorate the victory of the Corvette racing team driver Ron Fellows at the 2007 ALMS GT1 championship. Notable exterior features include special Arctic White paint, red grand sport style stripes on the front fenders and red and silver hash styled stripes incorporating a maple leaf similar to the livery present on the winning car. The interior had a red interior and complemented accenting on the seats, console and door panels. The arm rest features Ron Fellows' signature. Only 399 were made with 33 destined to the Canadian market.
The ZHZ was a standard Corvette equipped with the LS3 engine, 6-speed automatic transmission, vacuum actuated valve exhaust, F55 suspension and unique 7-spoke chrome wheels. It was developed for The Hertz Corporation's Fun Collection for 2008. 150 targa tops in 2008 and 350 convertibles were produced in 2009 in total. All cars were finished in yellow with a broad black stripe along the hood and roof.
GT1 Championship Edition (2009)
The GT1 Championship Edition is an optional package for the C6 that was unveiled in the 2009 New York Auto Show. It celebrates the Corvette C6.R's entry into the GT1 class of ALMS in 2009. This limited edition is based on either a 4LT equipped targa top, 4LT convertible or high performance Z06. Models wear the same velocity yellow "45U" body hue that adorns the C6.R or "41U" gloss black, along with a "Jake" graphic that spans the Championship edition's hood. Chrome wheels known as Gumby's are present on the targa top and convertible while the Z06 is fitted with chrome Spyder wheels. A body-colored spoiler shared with the ZR1 joins a "carbon pattern" engine cover, while a leather-wrapped ebony interior contains "GT1" embroidered on the head rests of the seats, the instrument panel and a center console armrest. Non-Z06 models also include a Z51 Performance Package and NPP Performance exhaust.
Original production numbers were slated to be 100 units of each model in each color (600 total), each carrying a premium over the standard models. But actual numbers amounted to 125 units in various numbers for each color code. This was due to the government takeover of General Motors.
Z06 Carbon Limited Edition (2011)
The Z06 Carbon Limited Edition was available as a 2011 model beginning in the summer of 2010. The car was available in two colors: Inferno Orange and an all-new Supersonic Blue. On the exterior, the car had black headlamps and mirrors, a ZR1-style spoiler, carbon fiber hood, and black carbon fiber rockers and splitter. Inside, the Z06 Carbon has ebony leather and suede seats with body color-matching stitching. Other improvements include Magnetic Selective Ride Control, a special carbon engine cover, 20-spoke black 19-inch front/20-inch rear wheels, and ZR1's carbon ceramic Brembo brakes. Although Chevrolet planned to sell 500 of the Z06 Carbon Limited Edition, only 252 units were produced.
Centennial Edition (2012)
Order code "ZLC" was an equipment package celebrating 100 years of racing heritage of Chevrolet. Offered exclusively in Carbon Flash Metallic, the Centennial Edition kit includes satin-black graphics and unique lightweight cast-spun aluminum Centennial Satin Black wheels that feature a thin red perimeter outline (on Z06 and ZR1 cars). All cars came with red brake calipers and featured Magnetic Selective Ride Control.
Inside, the car featured ebony leather upholstery and contrast stitching while the steering wheel and armrests featured microfiber suede accents. The headrests have an embossed Centennial Edition logo and the steering wheel hub carries the same "Louis Chevrolet 100" graphic found on the car's B-pillar and wheel center caps.

The Z06X was designed to be a factory built road race car similar to cars like the Porsche 911 GT3 Cup and Dodge Viper ACR-X. The concept car was built by GM with the help of Pratt & Miller Engineering. The Z06X features racecar components such as: carbon fiber adjustable rear wing, carbon fiber front splitter, full roll cage, fire suppression system, race seat, harness, carbon ceramic brakes, upgraded cooling system, polycarbonate rear window, adjustable coilovers, adjustable sway bars, and tow hooks; the radio, interior carpeting and sound-deadening materials have been removed. The suspension system was designed and supplied by Pfadt Race Engineering.
Main article: Chevrolet Corvette C6.R
The C6.R was a replacement for the C5-R, built by Pratt & Miller, and unveiled for its first competition at the 2005 12 Hours of Sebring endurance race of the American Le Mans Series. It came in second and third in its class, just behind the new Aston Martin DBR9 race car. It was put on display a week later at the New York International Auto Show next to the Z06.
In 2006, the Corvette C6.R won both American Le Mans GT1 Championships: Teams and Manufacturers. On March 17, 2007 it won the GT1 class in the 12 Hours of Sebring.
For Le Mans 2007, four C6.R's were on the entry list, the two Corvette Racing entries joined by single entries from the Luc Alphand Aventures and PSI-Motorsport teams.
The heart of the C6.R, its LS7.R motor, was crowned as Global Motorsport Engine of the Year by a jury of 50 race engine engineers on the Professional Motorsport World Expo 2006 in Cologne, Germany.
As the GT1 class dwindled, Corvette Racing switched to the GT2 class during the 2009 ALMS season.
For 2011, the aerodynamics of the ALMS cars were modified to be similar to the ZR1. This car has since won the 2011 24 Hours of Le Mans in the GTE-Pro and GTE-Am classes. In 2012, the Corvette C6.R won again in the GTE-Am category.
In addition to the American Le Mans Series, Corvette C6.Rs also race in the FIA GT1 World Championship. The GT1 cars are given more power and have less aerodynamics restrictions than the Le Mans cars, which follow GT2 regulations.
Riley Technologies built a GT2-class Chevrolet Corvette for the 2008 American Le Mans Series. The car also raced at the 2009 Petit Le Mans, where it beat both Pratt & Miller-built factory cars in qualifying.
Entered in the FIA GT3 European Championship series as a GT3 class car, the Z06-R is a modified production Z06. Changes were necessary to make the car endurance race ready. These include a stripped interior, full rollcage for safety, center-locking wheels, carbon fiber doors, rear deck spoiler and front splitter. The LS7 and LS3-engine and drivetrain are built by APP Racing Engines from the Netherlands. The car is not road legal.
Eight Z06-R were constructed by Callaway Competition GmbH in Leingarten, Germany, for the 2006 season. The French team Riverside campaigned a three car team.In an effort to achieve parity among the disparate participants of the GT3 Series, three forms of handicapping were applied by the FIA regulators: additional vehicle weight, ride height, and tire compound selection. The Corvettes were raced with all three handicaps employed. The Z06R won the FIA GT3 European Championship in its second year of entry. By 2011, all Z06-R teams discontinued their racing efforts in GT3, ending the car's FIA career. Z06-Rs are also campaigned in national championships.

Corvette Z06: A Quick History of a Fast Car
DETROIT – The all-new 2015 Chevrolet Corvette Z06 is the most capable in the history of the track-oriented model. The Z06 was first offered as an option package in 1963, directed at those who intended to use their Corvettes on a track.
The Z06 since has been offered in four of the Corvette’s seven production generations, each elevating the Corvette’s track capability:
Second generation (1963) – Developed under famed Corvette engineer Zora Arkus-Duntov, the first Z06 package offered enhanced handling and braking capability with an available, larger fuel tank that reduced the need for refueling during a race. Power came from a fuel-injected small block V-8 engine, supported by a four-speed manual transmission and Positraction rear axle. Only 199 were built.
- Fifth generation (2001-2004) – Combining a lower curb weight with higher horsepower, the fifth-generation Corvette Z06 was one of the fastest production cars on a track – a capability confirmed with a sub-8-minute lap around the Nürburgring. It was built on a unique fixed-roof hardtop body, with several lightweighting elements, such as thinner glass, a titanium exhaust system and more. Its unique LS6 small block engine delivered up to 405 horsepower through a six-speed manual transmission with specific, performance-optimized gearing. A total of 28,388 were built.
- Sixth generation (2006-2013) – The sixth-generation Corvette Z06 featured its own, bespoke aluminum frame that was 136 pounds lighter than the steel frame on standard Corvette models. Under the hood, the 505-horsepower LS7 7.0L small block featured racing-derived technologies, including titanium connecting rods and a dry-sump oiling system. The Z07 Performance Package added carbon-ceramic matrix brakes and Michelin Pilot Sport Cup tires, enabling the Z06 to run the Nürburgring in 7:22.68. A total of 27,979 were built, including 740 with the Z07 performance package.
- Seventh generation (2015) – The new 2015 Corvette Z06 is the most capable production Corvette ever. Developed in conjunction with the Corvette C7.R race car, it incorporates racing technology to deliver greater aerodynamic downforce, cornering grip and braking performance. With the available Z07 Performance Package – again fitted with Michelin Pilot Super Sport Cup tires and enhanced braking capability with carbon ceramic-matrix brakes – the new Z06 is faster on a track than the Corvette ZR1, in preliminary testing.
1963 Z06: Duntov’s legacy
The first Z06 was an option package on the iconic 1963 “split-window” Corvette, developed by Corvette’s legendary engineer and racing advocate Zora Arkus-Duntov. He successfully lobbied for the 1963 Corvette to offer a package for customers who intended to race the new car.
For those in the know, checking the RPO Z06 box on the Corvette’s order sheet added a thicker, 24mm (0.94-inch) front stabilizer bar, larger-diameter shock absorbers and springs that were nearly twice as stiff as standard parts. The Z06 package also featured:
- upgraded brake components, including sintered-metal brake linings, which stood up to heat and resisted wear better than conventional material
- a dual-circuit master cylinder and vacuum brake booster to enhance safety and reduce braking effort
These components would become industry standards but were still rare in regular-production vehicles of the era.
Possibly most significant for racing, the Z06 option could be combined with a larger, 36.5-gallon fiberglass fuel tank that allowed racers to stay on the track longer. Z06-equipped models quickly became known as “big tank” or “tanker” Corvettes and were originally limited to coupe models because the larger tank wouldn’t fit convertibles. Later, Chevrolet revised the package, making the regular 20-gallon fuel tank standard and the big tank an option. The change allowed the Z06 package to be ordered on a convertible. Only one is believed to have been built. The package originally added more than 40 percent to the Corvette’s base price. Aluminum knock-off wheels were also offered.
There was one engine available with the Z06 package – the 360-horsepower L84-code 327-cubic-inch small block, which featured an advanced mechanical fuel injection system. Corvette was a pioneer in fuel injection, having introduced it in 1957. A four-speed manual transmission and Positraction rear axle were also standard equipment.
In that pre-Internet era, few Corvette customers – even those with racing intentions – knew of the Z06 package. It wasn’t advertised, making word of mouth the primary source of information. Because most were purchased and used for racing, the attrition rate was comparatively high. Remaining, documented examples – especially the big-tank cars – are highly collectable.
2001-2004 Z06: Breaking the 8-minute Nürburgring lap
During the Corvette’s fifth generation, the Z06 name was reintroduced as a special 2001 model that took Corvette performance farther than it had ever been. Engineers started with the Corvette’s unique, limited-production hardtop body, which featured a fixed-roof design that was stiffer and lighter than the hatchback coupe. The car was further lightened with a titanium exhaust system, thinner glass, lighter wheels, conventional tires – in place of the standard run-flat tires - less sound-deadening material, a fixed radio antenna instead of a power antenna, and even a smaller, lighter battery.
The results shaved about 100 pounds off the weight of a conventional coupe model. The car also introduced rear-brake cooling ducts integrated in the rear fenders, which would become a signature styling cue.
On the other side of the power-to-weight equation is horsepower and to that end, the 2001 Z06 used an exclusive LS6 version of the Gen III small block engine. If featured unique internal parts, including a “hotter” camshaft and higher-compression pistons, and an enhanced cylinder block design for greater bay-to-bay breathing, helping it produce 385 horsepower. Further enhancements contributed to an increase to 405 horsepower in 2002. The engine was backed by a six-speed manual transmission with Z06-specific gear ratios.
Like the original 1963 Z06, the fifth-generation car included chassis and suspension components optimized for the track. Its exclusive FE4 suspension package featured larger-diameter, hollow stabilizer bars that also had thicker walls for greater stiffness; larger-diameter shock absorbers compared to standard models, quicker steering – 2.46 turns lock to lock vs. 2.66 on other models – and a larger wheel-and-tire package, featuring Goodyear Eagle F1 SC tires mounted on lighter, stiffer forged aluminum wheels.
By the end of its production run, the fifth-generation-based Corvette Z06 was already benefitting from technology used on the successful Corvette Racing program, including lightweight carbon fiber. A special 2004 24 Hours of Le Mans Commemorative Edition – acknowledging Corvette Racing’s historic 1-2 class finish at the famous 24-hour endurance race – used a carbon fiber hood to shave 10 pounds off the nose of the car, enhancing its balance.
The 2004 Corvette Z06 proved its capability on the global stage, when it became one of the first production cars at the time to run Germany’s famous Nürburgring road course in less than 8 minutes (7:56).
2006-2013 Z06: A foundation for success
The groundbreaking sixth-generation Corvette Z06 elevated Corvette to compete with the world’s most-capable supercars. A power-to-weight ratio of 6.2:1 was one of the best in the world, helping it run from 0 to 60 mph in about 3.7 seconds, through the quarter-mile in the low-11-second range and achieve a top speed of more than 190 mph.
The foundation of the Z06 was its own, dedicated aluminum chassis – the first unique frame for a special model Corvette.
The Z06’s aluminum frame was 136 pounds lighter than the comparable steel frame used in standard models and even incorporated a magnesium engine cradle, contributing to a curb weight of only 3,130 pounds. Mounted on that cradle was another leap in technology: The LS7 small block engine. Displacing 7.0L (427 cubic inches), it was the largest engine offered in the Corvette in more than 30 years – and the most powerful engine in Corvette’s history until the introduction of the Corvette ZR1.
The LS7 used airflow and lightweight technology, including titanium connecting rods and a dry-sump oiling system, derived from the Corvette Racing program to produce 505 horsepower.
Along with its unique frame and LS7 engine, the sixth-generation Corvette Z06 also featured:
- More rigid fixed-roof body style
- Wider front and rear fenders – including carbon fiber front fenders
- Unique rear spoiler and front splitter
- Front and rear brake-cooling ducts – including signature integrated rear-fender inlets
- Specific, lightweight 18-inch front and 19-inch rear wheels, with 275/35ZR18 front tires and 325/30ZR19 rear tires
- Large 14-inch (355 mm) front brake rotors with six-piston calipers and 13.4-inch (340 mm) rear rotors with four-piston calipers
- Unique stabilizer bars, spring rates and shocks.
The ultimate Corvette Z06 with the Z07 Performance Package incorporated a number of components used on the 205-mph Corvette ZR1, including carbon ceramic-matrix brake rotors, Michelin Pilot Sport Cup tires, additional carbon fiber exterior components and Magnetic Selective Ride Control. In 2012, a Z07-equipped Corvette lapped the Nürburgring in 7:22.68.
2015 Z06: The most capable ever
The new 2015 Corvette Z06 is the first Z06 to offer a supercharged engine, an automatic transmission and, thanks to a stiffer aluminum frame, a removable roof panel. It is also the most track-capable Corvette, ever.
It was developed in conjunction with the Corvette C7.R race car with technology proven through Corvette Racing, the most successful program in the Tudor United Sports Car Challenge series, formerly the American Le Mans Series.
A new, supercharged 6.2L engine, rated at an estimated 625 horsepower (466 kW), powers the Z06. It is also one of the industry’s only supercars to offer the choice of two transmissions – a seven-speed manual and an all-new eight-speed automatic transmission. Developed by General Motors, the paddle-shift eight-speed offers full manual control, delivering quick, seamless shifts that rival the world’s best dual-clutch/semi-automatic transmissions.
An available, carbon fiber aero package adds a carbon fiber front splitter with aviation-style winglets, carbon fiber rocker panels and a larger rear spoiler with a fixed wickerbill – a small, vertical tab at the edge of the spoiler that significantly increases downforce.
The available Z07 package adds larger winglets, an adjustable, see-through center section on the rear spoiler, Michelin Pilot Super Sport Cup tires and carbon ceramic-matrix brakes. With this package, the Corvette Z06 will deliver the most aerodynamic downforce of any GM production car.
The 2015 Corvette Z06 goes on sale in early 2015.
