CHEVROLET CORVETTE C5

:For an outline of all the Chevrolet Corvette generations see Main articles: Chevrolet Corvette

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. 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, 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 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 removeable targa top panel as with the hatchback coupé) with a roofline shape similar to that of the convertible. The hardtop became the high-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.
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. A number of factors are responsible for this: first is the relatively light weight of the C5 (a curb weight under 3,300 lb); second is the C5's low drag coefficient; and third is the vehicle's tendency to upshift into the higher gears as soon as possible (which with the manual transmission's Computer-Aided Gear Shifting, results in an obligatory shift from 1^st gear directly to 4^th gear under certain driving conditions, although this "feature" of the manual transmission can be inhibited through the use of an aftermarket device).
Suspension options 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.
Although sometimes criticized for its arguably liberal use of light-weight materials (e.g., plastics, plywood, etc.) in areas such as interior components, which were often (and perhaps unfairly) interpreted as "cheap-and-easy" substitutes for other higher-quality materials, the C5 quickly became regarded as the best performance vehicle available for the price. In some cases, it provided performance equal to, or better than, vehicles approaching 2-3 times its sticker price.

Z06

:Main articles: 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.
Like with the ZR-1, Chevrolet found that increasing the power output did the C5 platform little good without additional modifications to bring the rest of the car up to par. Starting with the most structurally rigid body style offered (the hardtop or FRC), uprated FE4 suspension, larger wheel rims and tires, revised gearing ratios, and functional brake cooling ducts became part of the total package. The Z06 is 38 pounds lighter than a standard C5 hardtop thanks to weight-saving measures such as a titanium exhaust, thinner glass, lighter wheel rims, non-EMT tires, reduced sound proofing, fixed rear radio aerial, and a lighter battery. Starting with the 2002 model year, the LS6 engine was uprated to 405 hp (302 kW) thanks to a larger volume air intake, stiffer valve springs, lighter sodium filled valves, more aggressive cam phasing and lift, revised pistons, and revised block.
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. Not as apparent to the naked eye, 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 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^[1] seconds. The Z06 is capable of matching or beating the 0-60 acceleration times of some of the world's premier sports cars, including the Ferrari 360 and the Porsche 911 turbo, making it one of the best performance bargains under $100,000.

Indianapolis 500 Pace Car Replica

In 1998, the newly-introduced convertible version of the C5 was chosen to pace the Indianapolis 500 race, and a 'Pace Car Replica' (RPO Z4Z) was offered to the public. Aside from lacking the equipment necessary for actual pace car duties (light bar, special racing harnesses, etc.), there was little difference between the Pace Car Replica C5 and the vehicle that actually saw duty during the race^[2]. The Pace Car Replica package consisted of a special paint color ("Radar Blue"), unique interior colors (black and yellow), painted yellow rims, and special pace car decals. The Pace Car Replica package also included other optional equipment: the newly-introduced Active Handling System (RPO JL4); an electronically-tuned AM/FM radio with CD player and a Bose speaker system; an electronic dual-zone heating & air conditioning system; and leather adjustable sport bucket seats.
While regarded by many (including Corvette fans) as the most garish Corvette appearance package offered to date, the 1998 Pace Car Replicas nevertheless enjoy a strong and loyal following of owners and collectors.

50^th Anniversary Edition

A '50^th Anniversary Edition' (RPO Z25) was offered during the 2003 model year to commemorate a half-century of Corvette production. Available as either a coupé or convertible (no Z06 version offered), the 50^th Anniversary Edition came with a special shade of red paint ("Anniversary Red Metallic") and shale two-tone leather interior; Anniversary Edition convertibles were adorned with a shale-colored soft top as well. A new option for Corvette in 2003, the F55 Magnetic Selective Ride Control Suspension was standard on the 1SC Anniversary Edition vehicles. Special champagne-colored painted aluminum rims, embroidered upholstery trim, and badges completed the Anniversary Edition package. Also included were all of the convenience options offered on the upscale Corvette models.
A slightly modified 50^th Anniversary Edition Corvette was chosen to pace the Indianapolis 500 race in May 2002; then the production vehicle became a centerpiece of the subsequent 50^th Anniversary Celebration, sponsored by Chevrolet. Festivities included gatherings in Nashville, Bowling Green, and St. Louis. Thousands of Corvettes and their owners arrived from all over the country to participate in the events marking the vehicle's 50^th year of production.^[3]

24 Hours of Le Mans Commemorative Edition

During the 2004 model year, a '24 Hours of Le Mans Commemorative Edition' package (RPO's Z15 & Z16) was offered as a option for all three C5 models (hatchback coupé, convertible, Z06) in celebration of the C5-R "1-2" in-class finishes at Le Mans. The package consisted of a special paint color ("Le Mans Blue Metallic"); shale two-tone leather interior; and wide, silver-and-red stripes optionally applied down the center of the car (Z06 only). Commemorative Edition convertibles received a shale-colored soft top, and the Z06 version (dubbed the "Z16" after its RPO for the Le Mans Commemorative Edition) received a carbon fibre hood as a further weight-reduction measure. Special commemorative badging, headrest embroidery, and brightly-polished wheel rims (a first on the Z06) with unique centercaps completed the package.

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.
