The C5 Chevrolet Corvette (1997-2004) moved the transmission to the rear axle as a transaxle, giving the car near 50/50 weight distribution, and built the chassis on hydroformed steel perimeter frame rails with balsa-cored composite floors. Every C5 carried the all-aluminum 5.7L LS1 V8, rated at 345 hp from 1997 through 2000 and 350 hp from 2001 on. The Z06, added for 2001 on the fixed-roof body, ran the LS6 at 385 hp, then 405 hp for 2002-2004.

Platform and chassis
The C5 Corvette (1997-2004) sits on a backbone chassis with two full-length hydroformed steel perimeter rails, each formed from a single tube instead of the 14 welded-up sections the C4 used. The floors are composite panels with a balsa wood core, and the body panels are composite over that frame. Torsional stiffness went up sharply over the C4, which is why C5 convertibles do not need the extra bracing owners expect from earlier drop-top Corvettes. Suspension is short/long arm at all four corners with transverse composite leaf springs. The 1997 car launched as a hatchback coupe only; the convertible returned for 1998, and it got a real trunk, the first on a Corvette convertible since 1962.
Drivetrain layout
The C5 uses a rear transaxle. The engine stays up front, a torque tube runs the length of the car, and the transmission bolts to the differential at the rear axle. That layout puts weight distribution close to 50/50 and is the reason a C5 has almost no transmission tunnel intrusion up front compared to a C4. It also means clutch jobs on manual cars are done at the back of the car, which surprises people who have only wrenched on earlier Corvettes.
Engines
- LS1, 5.7L (346 cu in) aluminum V8: standard in every C5. 345 hp and 350 lb-ft from 1997 through 2000. For 2001 the rating rose to 350 hp with a bump in torque. This was the first of the Gen III small blocks, with an aluminum block, deep-skirt design, and coil-near-plug ignition.
- LS6, 5.7L aluminum V8 (Z06 only): 385 hp and 385 lb-ft for 2001. For 2002 it went to 405 hp and 400 lb-ft with a more aggressive cam, lighter valvetrain, and higher-flow heads, and it held that rating through 2004.
Transmissions
Two choices across the run: the 4L60-E four-speed automatic and the Borg-Warner (later Tremec) T-56 six-speed manual, both mounted at the rear as part of the transaxle. Manual cars carry the CAGS skip-shift solenoid that forces a 1-4 shift under light throttle; most owners defeat it with a cheap plug. The base manual carries RPO code MN6; the Z06 got its own M12 version of the six-speed with shorter ratios in most gears. No automatic was ever offered in the Z06.
Year-by-year changes
- 1997: Coupe only, LS1 at 345 hp, new chassis and drivetrain throughout.
- 1998: Convertible added. Active Handling stability control arrives as a midyear option (RPO JL4). An Indy 500 Pace Car replica convertible, purple with yellow wheels and graphics, is the year's collector piece.
- 1999: Fixed-roof coupe (FRC) added as the lightest, cheapest body, a notchback with a solid roof. Head-up display becomes available.
- 2000: Minor running changes; new wheel designs.
- 2001: Base LS1 rises to 350 hp. Z06 replaces the FRC, using that stiffer fixed-roof body with the 385 hp LS6, FE4 suspension, titanium exhaust, and wider wheels. Active Handling becomes standard on all models.
- 2002: Z06 climbs to 405 hp.
- 2003: 50th Anniversary Edition (coupe and convertible) in Anniversary Red with champagne wheels. Magnetic Selective Ride Control (F55) debuts, the first magnetorheological dampers on a Corvette; it is standard on Anniversary cars and optional on other coupes and convertibles, but never offered on the Z06.
- 2004: Final C5 year. Commemorative Edition offered on all bodies in Le Mans Blue; the Z06 version got a carbon fiber hood, the first carbon fiber exterior panel on a production Corvette and on any North American production car. F55 remains optional on coupes and convertibles.
Trims and variants
Body styles were the hatchback coupe with removable roof panel, the convertible (from 1998), and the fixed-roof coupe (1999-2000), which became the basis for the Z06 (2001-2004). The Z06 is the one buyers chase: LS6 power, thinner glass, lighter wheels, stiffer FE4 suspension, and no automatic option. Notable option codes owners look for include Z51 performance suspension on base cars, F45 real-time damping, and F55 Magnetic Selective Ride, standard on the 2003 Anniversary cars and optional on 2003-2004 coupes and convertibles.
Asked all the time
What engines came in the C5 Corvette (1997-2004)?
Every base C5 Corvette from 1997 through 2004 used the 5.7L aluminum LS1 V8, rated 345 hp from 1997-2000 and 350 hp from 2001-2004. The Z06 (2001-2004) used the 5.7L LS6, rated 385 hp in 2001 and 405 hp for 2002-2004.
Which C5 Corvette years are the best to buy?
For a base C5 Corvette, 2001-2004 cars get the 350 hp LS1 and standard Active Handling stability control. The 2002-2004 Z06 with the 405 hp LS6 is the most sought-after C5. The 1999-2000 fixed-roof coupe is the lightest and often the cheapest way into the platform.
What is the difference between the C5 Z06 and a base C5 Corvette?
The Corvette Z06 (2001-2004) uses the fixed-roof body, the LS6 engine (385 hp in 2001, 405 hp in 2002-2004), a Z06-specific M12 six-speed manual, stiffer FE4 suspension, wider wheels, thinner glass, and a titanium exhaust. It was manual-only; no automatic Z06 exists.
What transmissions did the C5 Corvette use?
The C5 Corvette (1997-2004) offered the 4L60-E four-speed automatic or the T-56 six-speed manual, both mounted at the rear axle as a transaxle. Manual cars have the CAGS 1-to-4 skip-shift feature, which is commonly defeated with an inexpensive bypass plug.
When did the C5 Corvette Z06 go from 385 to 405 hp?
The Corvette Z06 launched in 2001 with the LS6 at 385 hp. For 2002 the LS6 was revised with a hotter cam, better-flowing heads, and a lighter valvetrain, raising output to 405 hp, and it stayed at 405 hp through the final 2004 model year.
What is special about the 2003 50th Anniversary C5 Corvette?
The 2003 Corvette 50th Anniversary Edition, offered as a coupe or convertible, came in Anniversary Red with champagne-painted wheels and standard F55 Magnetic Selective Ride Control, the first magnetorheological dampers on a Corvette. The F55 system was also optional on other 2003-2004 coupes and convertibles, but not on the Z06.
