C6

The new sixth-generation Corvette gets an overhaul of the suspension geometry, all new bodywork with exposed headlamps (for the first time since 1962), a larger passenger compartment, a larger 6.0 L engine, and a much higher level of refinement. Overall, it is 5.1 inches (13 cm) shorter than the C5, but its wheelbase has increased by 1.2 inches (3 cm). It is also one inch (2.5 cm) narrower, making for a smaller, sportier Corvette. The reduced dimensions were in response to criticism that the fifth-generation Corvette looked too wide—the new body gives the impression of a much sleeker, faster car. The 6.0 L LS2 V8 produces 400 hp (298 kW) at 6000 rpm and 400 ft·lbf (542 N·m) of torque at 4400 rpm. Its redline is increased to 6500 rpm. The C6 retains its relatively good fuel economy, in part by upshifting to higher gears as soon as possible and in part due to its relatively low drag coefficient and low weight. Equipped with an automatic transmission, the C6 achieves 18/27 mpg (city/highway), and the manual transmission version is slightly better at 18/28. However some Corvette owners were surprised to find that the C6's manual transmission is fitted with Computer Aided Gear Selection (CAGS), which has been included in all manual transmission Corvettes since 1989. CAGS requires the driver to shift from 1st directly to 4th when operating at lower RPMs by using a solenoid to block out 2nd gear. While this boosts the EPA's derived fuel economy, thus allowing the buyer to avoid paying the "gas guzzler" tax, it is an open secret that more than a few C6 owners with manual transmissions simply have a $20 aftermarket part (CAGS eliminator) fitted to their vehicle to re-enable a normal 1-2-3-4-5-6 sequence at any engine speed

C6-Z06

The new Z06 arrived as a 2006 model in the third quarter of 2005. It has a 7.0 L (7,008 cc/427.6 in³) version of the small block engine codenamed LS7. Officially certified output is 505 hp (377 kW). Its performance is similar to the Ford GT and the Dodge Viper SRT-10. Official performance figures indicate that the Z06 can reach 60 mph in just 3.7 seconds from a standing start in first gear. In addition to the larger engine, the C6 Z06 has a dry sump oiling system, ensuring proper engine lubrication during periods of high (lateral) acceleration and allowing the engine to be mounted low inside the chassis. Connecting rods made out of titanium further lighten the reciprocating mass of the engine while being stronger than the steel rods they replace. In a radical departure from anything Chevrolet has ever done before, the primary structural element of the C6 Z06 is aluminum instead of steel as on the non-Z06 cars. The hydroformed aluminum frame remains dimensionally identical to its steel brethren but is significantly lighter. The front fenders are made of carbon fiber by Plasan USA to reduce weight, while wider rear fenders allow for the wider tires necessary to deal with the engine's increased power. The Z06 officially weighs 3132 lb (1421 kg), giving it a power to weight ratio of 6.2 lb/hp (3.8 kg/kW or 361 bhp per tonne). The C6 Corvette Z06 is the first 500+ hp production car to avoid the US government Gas Guzzler tax. 2007 Z06 had minor changes including retuning of the suspension after some magazine test drivers announced the suspension did not perform up to their original estimates. Chevrolet announced the models were pre released, and for 2007 they would retune the damping. In more recent tests the Corvette has shown improved driveability and track manners. 2008 Z06 received the new TR6060 six speed manual transmission which replaces the T-56.

C6-ZR1

The Corvette variant, now officially known as the ZR1 was first reported by several print and online publications who were speculating that Chevrolet was developing a high performance production version of the Corvette and are internally calling it blue devil. The production version is expected to debut at the 2008 North American International Auto Show and be available as a 2009 model. The car was originally rumored to feature a supercharged "LS9" engine producing more than 650 hp (485 kW) with prices reported to exceed $100,000 USD.On April 13, 2007, GM did finally confirm the existence of the Blue Devil project, in an interview with Car and Driver. Power levels were confirmed to be between 600 and 700 horsepower (447 to 521 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 recently published an article stating the super Corvette car will likely be labeled the Z07, and will be released in late 2008 for the last year of the C6 body style.

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, just behind the new Aston Martin DBR9 racecar. It was put on display a week later at the New York International Auto Show next to the Z06. Later, in the 2005 24 Hours of Le Mans, it made up for Sebring by placing first and second in the GT1 car class after a lengthy duel with the Aston Martin team's DBR9 racers by finishing 5th and 6th overall, a considerably high finish for a GT class car. Corvette C6.R went on to win every race it entered in the 2005 ALMS season. It defeated the Aston Martins again at Road Atlanta and Laguna Seca. Olivier Beretta and Oliver Gavin took home the drivers championships. 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 . When you consider the breadth of global motorsport and the number of outstanding engines competing on circuits week in and week out, the award becomes even more significant. The Carsport Holland Corvette C6.R won the 2007 24 Hours of Spa, beating a field of Aston Martins, Maseratis and Lamborghinis in the GT1 class.

C5

The Chevrolet Corvette C5 is a sports car which started in 1997 and ended with the 2004 model year. It is the fifth generation of Chevrolet Corvettes built and marketed by Chevrolet. The C5 was a radical change from the previous generation. Designed from the outset as a sturdy convertible (as opposed to a coupé that was subsequently weakened by the removal of the roof structure in order to accommodate demand for a convertible model), the car now had a hydroformed box frame. The transmission was moved to the rear of the car to form an integrated, rear-mounted transaxle assembly which was connected to the all-new LS1 engine via a torque tube; this engine/transmission arrangement helped facilitate a desirable 50-50 (percentage, front-rear) weight distribution for the vehicle. The LS1 engine initially produced 345 hp, but that was increased slightly in 2001 to 350 hp (261 kW). The 4L60E automatic transmission carried on from previous models, but the manual was replaced by a Borg-Warner T-56 6-speed. Gone were the squeaks and rattles of the C4[1], and in replacement was an incredibly strong frame that would last for at least two more generations. By all measures, the new C5 was better in every aspect than the C4 it replaced.
The styling of the C5 was also a departure from the trend set by the previous-generation Corvette. Whereas the styling of the C4 had largely been a simplification of the C3 hatchback design, straightening out the complex curves of the car to give it sleeker lines, the C5 reversed that somewhat. The vehicle now had a more rounded and graceful appearance that helped to recapture some of the aggressive looks of the C3 without compromising aerodynamics. In the inaugural model year (1997), only the hatchback coupé was offered, with the convertible — the first to offer a trunk since 1962 — following in 1998. 1998 also saw the C5 convertible pacing the Indianapolis 500, and a replica pace car edition was sold; C5 Corvettes subsequently paced the 2002 and 2004 Indianapolis 500 races, but no replica pace car versions were offered during those model years. In 1999, a third body style, the hardtop (also referred to as the "fixed-roof coupé" or "FRC"), was added to the lineup. This body style, as its name suggests, featured a fixed top (no removable targa top panel as with the hatchback coupé) with a roofline shape and trunk space similar to that of the convertible. The hardtop became the top-performance Z06 in 2001, but for two model years was offered as a variant of the base-model Corvette.
Aside from cosmetic differences (new rim styles, paint colors, pace car/commemorative editions in 1998, 2003, and 2004, etc.) and new offerings for optional equipment, there were few fundamental changes from one model year to the next within the production run of the C5. One of the more popular "high-tech" options introduced to the Corvette line was a head-up display or HUD, while another innovation was the Active Handling System (first available as an option in 1998, then standard on all models in 2001).
In contrast to the (largely deserved) reputation of high-performance vehicles for poor fuel economy, the C5 achieves comparatively high EPA ratings of 18/26 mpg (city/highway) with the automatic transmission, and 18/28 with the manual transmission, allowing it to avoid the "gas guzzler" tax that is levied against most other vehicles in the Corvette's class. Suspension choices for the base model C5 were limited to the standard suspension (RPO FE1), with options for either the autocross-inspired FE3 Sport Suspension (included with the Z51 Performance & Handling Package and standard on the 1999-2000 FRC); or the F45 Selective Ride Control Suspension, which permitted "on-the-fly" driver selection of different ride characteristics (sport or touring). Late in the production run (starting with the 2003 model year), the F55 Magnetic Selective Ride Control Suspension replaced the F45 as the third suspension choice. The racing-inspired FE4 suspension used for the Z06 is stiffer again than any offered on the base model C5, and is unique to that model with no optional suspensions offered.
Factory performance figures give a 0-60 mph acceleration time for the C5 convertible (2004 model year with a 6-speed manual transmission) of 4.66 seconds; a standing quarter mile is quoted by Chevrolet as 12.98 seconds at 114 mph. With the automatic transmission, the performance figures are slightly poorer: 0-60 mph in 5.13 seconds, with a standing quarter mile in 13.63 seconds at 108 mph.

C5-Z06

A successor to the ZR-1 made its debut in 2001 as the Z06, giving a nod to the high-performance Z06 version of the C2 Corvette of the 1960s. Instead of a heavy, double-overhead cam engine like the ZR-1, the Z06 used a high-output, tuned version (designated LS6) of the standard LS1 Corvette engine, which initially produced 385 hp (287 kW). Although its total horsepower output was less than that of the last ZR-1, the Z06 was much lighter, and could out-perform the ZR-1 in every category except top speed. It also cost substantially less money than the ZR-1. The 2004 Z16 Commemorative Edition was equipped with a carbon fiber hood, saving an additional 20 pounds of weight. Other unique characteristics of the Z16 (Commemorative Edition Z06) are the polished aluminum rims, special paint color and striping, and commemorative-edition badging and centercaps; though not as outwardly apparent, the Z16 also received shock damping tuning for improved handling. The Z16 was a limited production vehicle, with only 2025 Z16s produced in 2004 (the only year of production); of that number, 325 went overseas, leaving North America with approximately 1700.Factory performance figures for the 405 hp (302 kW) version of the Z06 give an acceleration time from 0-60 mph as 3.9 seconds. Owner-drivers have reportedly achieved impressive quarter-mile times of 11.7[2] seconds. The Z06 is capable of matching or besting the 0-60 acceleration times of some of the world's premier sports cars, including the BMW Z8, Ferrari 360, and Porsche 911 Turbo (Type 996), making it one of the best performance bargains under $100,000.

C5-R

The C5-R was a racecar built by Pratt & Miller for GM Racing. It was based on the C5 road car but had a longer wheelbase, wider track, an enlarged 7.0 L V8 and different bodywork with exposed headlamps. It is raced in the American Le Mans Series in the GTS Class and has been to four 24 Hours of Le Mans races.

2001 The car's remarkable 2001 racing season produced eight victories in ten races, including an overall win in the 24 Hours of Daytona and a one-two finish in the GTS class at Le Mans.

2002 In 2002 the C5-R repeated its one-two victory at Le Mans and also dominated the GTS class in the American Le Mans Series. A new transaxle unit replaced the previous year's separate transmission and differential. Corvette faced stiff competition from the new Prodrive Ferrari 550, which led for a good number of laps but had problems late, leaving the victory to Corvette.

2003 In 2003, the Automobile Club de l'Ouest placed additional restrictions on all 24 Hours of Le Mans competitors, reducing power by 10% in an attempt to slow the cars. At the 2003 season-opening 12 Hours of Sebring race, the C5-Rs remained in winning form, with one of them finishing first in class and eighth overall. Also in 2003 the yellow paint was dropped in favor of a special red, white, and blue color scheme to commemorate the Corvette's 50th anniversary. However, at Le Mans the Prodrive Ferraris spoiled the anniversary and hopes for a three-in-a-row victory in the GTS class.

2004 Corvette C5-R came back in 2004 and won the 24 Hours of Le Mans in their class. The Prodrive Ferrari led most of the race, but with under 12 hours to go both the Prodrive cars had problems causing them to pit and lose laps. The Corvettes went on to finish 1-2, with the #64 car finishing 16 laps ahead of the lead Ferrari.

2005 Although in the process of becoming superseded by the C6-R, the Corvette C5-R was not finished with its racing successes. In FIA GT, the new Corvette Europe team won races at Imola and Zhuhai. The Euro team also managed a number of podium finishes. In the ALMS, the Pacific Coast Racing team achieved some podiums behind the factory C6-R.

2006 The C5-R returned to Le Mans (France) for the first time as a non-factory entry, run by Le Mans regular Luc Alphand. It finished third in the GT1 class behind the C6-R and Prodrive Aston Martin.
2007 Alphand's squad will again run the C5-R at the Le Mans 24 Hour race, in pairing with a C6-R acquired from Corvette Racing.

C4

The highly anticipated fourth generation Corvette began production in March 1983 as a 1984 model. The 1983 model year was skipped due to production problems, although 44 prototype 1983 models were completed. All 44 1983 model year prototypes assembled were crushed except for one (the 23rd produced), which is displayed at the National Corvette Museum in Bowling Green, Kentucky. The C4 was praised for its sleek styling and its groundbreaking aerodynamic design. The C4 coupe incorporated a rear glass hatch, like the 1982 Collector's Edition, for much improved cargo access. It also had all new brakes with aluminum calipers. The Corvette C4 came standard with an electronic dashboard with digital liquid crystal displays for the speedometer and tachometer. The C4 was a complete and total redesign except for its engine, and the emphasis was on handling. The C4 Corvette was proclaimed the best handling production car ever when it was released[citation needed]. This handling came with the penalty of a harsh, uncompromising ride.
From 1984 through 1988, the Corvette used an unusual "4+3" transmission — a 4-speed manual coupled to an automatic overdrive on the top three gears. It was designed to help the Corvette meet U.S. fuel economy standards. The transmission was problematic and was eventually replaced by a much more modern ZF 6-speed manual gearbox in 1989. This new transmission was also the first to feature Computer Aided Gear Selection (CAGS), which used a solenoid to lock out 2nd gear during certain driving conditions. Beginning in 1985, the 230 horsepower L98 engine with tuned port fuel injection was installed in most Corvettes, replacing the throttle body fuel injected powerplant. For the 1992 model year, the 300 horsepower LT1 engine was introduced, which significantly improved the performance of the base C4 cars. Also introduced in 1992 was Acceleration Slip Regulation (ASR), a form of traction control which utilized the Corvette's brakes, spark retard and throttle close-down to prevent excessive rear wheel spin, and possible loss of control. The traction control device could be switched off if desired. In 1996, the final year of C4 production, the 330 hp (246 kW) LT4 V-8 was installed in all manual transmission equipped Corvettes; all 1996 Corvettes with automatic transmissions utilized the LT1. The C4's incredible handling characteristics and cornering ability allowed it to dominate SCCA events and races during the 1980s.
This first year model of the C4 carried over the L83 engine from the previous generation of Corvette. The L83 engine had a unique fuel delivery method, named "Crossfire", a dual-throttle-body injection system. The 1984 and 1985 were the only C4's to lack the third brake light (CHMSL, Center High Mounted Signal Light) which was required by federal law beginning in 1986

C4-ZR1

In 1986, the Corvette team approached Lotus, then a GM subsidiary, with the idea of developing an ultra-high performance vehicle based on the C4 Corvette. With input from GM, Lotus designed a new engine to replace the traditional pushrod L98 V-8 that powered the standard C4. The result was the LT5, an aluminum-block V-8 with the same bore centers as the L98, but with four overhead camshafts and 32 valves. Lotus designed a unique air management system for the engine to provide a wider power band by shutting off 8 of the 16 intake runners and fuel injectors when the engine was at part-throttle, while still giving the ZR-1 a stellar 375 hp when at wide open throttle.

In addition to the engine, Lotus aided the development of the ZR-1's standard "FX3" active suspension system.

In 1991, all Corvettes received updates to body work, interior, and wheels. The convex rear fascia that set the 1990 ZR-1 apart from the base model was now included on L98 Corvettes, making the styling of the expensive ZR-1 even closer to that of the base cars. The most obvious difference remaining between the base and ZR-1 models besides the wider rear wheels was the location of the CHMSL (center high mounted stop lamp), which was integrated into the new rear fascia used on the base model, but remained at the top of the rear-hatch on the ZR-1's.

Further changes were made in 1992: ZR-1 badges were displayed on both front fenders and traction control was added as a standard feature. In 1993, Lotus redesigned the cylinder heads and valvetrain of the LT5, resulting in a horsepower increase from 375 to 405. In addition, a new exhaust gas recirculation system improved emissions control. Production of the ZR-1 ended in 1995, after 6,939 cars had been built

C3 (STINGRAY)

The third generation, patterned after Chevrolet's "Mako Shark II" (designed by Larry Shinoda), started in 1968 and ended in 1982. This generation has the distinction of being introduced to the motoring public in an unorthodox — and unintended — fashion. 1968 marked the introduction of Mattel's now-famous Hot Wheels line of 1/64-scale die cast toy cars. General Motors had tried their best to keep the appearance of the upcoming car a secret, but the release of the Hot Wheels line several weeks before the Corvette's unveiling had a certain version of particular interest to Corvette fans: the "Custom Corvette", a GM-authorized model of the 1968 Corvette.

In 1969, GM enlarged their small block again to 350 cu in (5.7 L), and in 1970, the 427 big block was enlarged to 454 cu in (7.4 L). Power peaked in the 1970 and 1971 models, with the 1970 LT-1 small block putting out 370 hp (276 kW) and the 1971 454 big block having its last year of big power with 425 hp (317 kW). In 1972, GM moved to the SAE Net measurement for power (away from the previous SAE Gross standard), which resulted in lower values expressed in HP. Along with the move to unleaded fuel, emission controls, and catalytic converters, power continued to decline and bottomed out in 1975 — the base ZQ3 engine put out 165 hp (123 kW), and the optional L82 engine put out 205 hp (153 kW). Power remained fairly steady for the rest of the C3 generation, ending in 1982 with the 200 hp (149 kW) L83 engine.

Styling changed subtly over the generation. Minor trim changes occurred through the 1972 model. In 1973, the Corvette dropped the front chrome bumpers for a urethane-compound "5 mph" bumper but kept the rear chrome bumpers. In 1974, the rear chrome bumpers became urethane as well, resulting in the first ever chrome-less production Corvette. 1976 was the last year in which the Stingray badge was used, and 1978 saw the introduction of a glass bubble rear window. In 1980, the Corvette got an integrated aerodynamic redesign that resulted in a significant reduction in drag. In 1982, an opening rear hatch was offered for the first time on the Corvette available on the collectors edition model only. A new engine featuring cross fire injection, a fuel injection carburator hybrid, was also introduced that year as the L83. It was the only engine available in 1982, and was not offered with a manual transmission.

C6-Z06-R

Entered in the FIA-GT 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 engine and drivetrain are stock but the former is mapped for 98 octane race fuel. The result is a 7200 rpm redline, 200 higher than stock and 10 extra horsepower. The massive power output of the 7 L engine, coupled with the production cars' proven roadholding calls into question whether or not the FIA will place restrictions on the car. The Z06-R is not road legal. Eight Z06R were constructed by Callaway Competition GmbH Leingarten Germany for the 2006 season. Notable race drivers were Klaus Ludwig, Germany, John Heinricy, USA and Uli Berberich-Martini, Germany. 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, and to their credit were still able to run at or near the front of the field against notable such as Viper, Aston Martin, Porsche and Ferrari.

C2 (MID- YEAR)

The second generation, or mid-year, was designed by Larry Shinoda with major inspiration from a previous unproduced design called the "Q Corvette" by Peter Brock and Chuck Pohlmann, and under the styling direction of Bill Mitchell, started in 1963 and ended in 1967. 1963 would see the introduction of the new Corvette Sting Ray coupé with its distinctive split rear window and fake hood vents as well as an independent rear suspension. The split rear window was discontinued in 1964 due to safety concerns. Because they made the design too busy, the hood vents were also cut. Power for 1963 was at 360 hp (268 kW) hitting 375 hp (280 kW) in 1964.

Four-wheel disc brakes were introduced in 1965, as was a "big block" engine option (the 396 in³ (6.5 L) V8). Side exhaust pipes appeared on the 1965 Sting Ray and persisted through 1969. Chevrolet would up the ante in 1966 with the introduction of an even larger 427 in³ (7 L) version, creating what would be one of the most collectible Corvettes ever. 1967 saw a L88 version of the 427 introduced which was rated at 430 hp (321 kW), but unofficial estimates place the actual output at 550 hp (410 kW) or more. Only twenty such engines were placed in the 1967 Corvette, and the cars can fetch US$1,000,000 or more in auction today. From 1967 to 1969, the 1282 ft³/min Holley triple two-barrel carburetor, or Tri-Power, was available on the 427. The 1967 Corvette originally was going to be the first of the C3 generation; however, due to delays the C3 had to be put off until 1968. Other early options available on the C2 included an AM-FM radio (mid 1963), air conditioning (1963), a telescopic steering wheel (1965) and headrests, presumably to prevent whiplash (1966).
The 1965 introduction of the 425 hp 396 in³ big block was ultimately the harbinger of doom for the Rochester fuel injection system. The 396 in³ option cost $292.70 while the fuel injected 327 in³ engine cost $538.00. Few people could justify spending $245 more for 50 hp less. When only 771 fuel-injected cars were built in 1965, Chevrolet stopped the program.

The popular Z06 performance package on the C5 and C6 model Corvettes is named after a Z06 performance option dating back to the 1963 model year

C1 (SOLID AXLE)

The first generation is most commonly referred to as a solid-axle, based on the fact that independent rear suspension (IRS) was not available until 1963. The first generation started in 1953 and ended in 1962, with the noteworthy addition of optional fuel injection in mid-1957 (also available on Chevrolet Bel Air). Fuel injection first saw regular use on a gasoline engine two years prior on the Mercedes-Benz 300SL "gullwing" roadster. Although the Corvette's GM-Rochester injection used a constant flow system as opposed to the diesel style nozzle metering system of the Mercedes', it nevertheless produced about 290 hp (216 kW) (gross). The number was listed by Chevrolet's advertising agency for the 283 hp/283in³ (4.6L) "one hp per cubic inch" slogan, making it one of the first mass-produced engines in history to reach 1 hp/in³. In 1962, the GM small block was enlarged to 327 cu in (5.4 L) and produced a maximum of 360 hp (268 kW). Other early options included power windows (1956), hydraulically operated power convertible top (1956), four speed manual transmission (late 1957), and heavy duty brakes and suspension (1957). The car nearly died in 1955, but that year a V-8 replaced the six-cylinder used in 1953 and 1954.

C7

According to several issues of Motor Trend magazine, a C7 Corvette will debut in the 2010 calendar year????????????
