The Chevrolet Corvette, an iconic symbol of American sports car heritage, has captivated enthusiasts for decades. For those looking to delve into the specifics of the C5 generation, understanding the “Corvette Year By Year” evolution is key. This article provides a comprehensive breakdown of the changes and improvements introduced each model year from 1997 to 2004, offering a detailed guide for enthusiasts, buyers, and anyone interested in the C5 Corvette’s rich history.
1997: The Dawn of the C5 Corvette
The 1997 model year marked a monumental shift with the introduction of the C5 Corvette, a completely redesigned vehicle from the ground up. This fifth-generation Corvette debuted with significant advancements in technology, performance, and overall design. Notably, the ’97 Corvette offered two suspension packages: the standard Base (FE1) and the more performance-oriented Z51 (FE3). Cars equipped with the Z51 package came standard with a power steering cooler, among other enhancements that prepared it for more demanding driving conditions. Under the hood, all 1997 Corvettes housed the new LS1 engine, producing an impressive 345 horsepower at 5600 RPM and 350 lb-ft of torque at 4400 RPM. This engine established a new benchmark for Corvette performance and reliability.

1998: Expanding the C5 Lineup and Introducing Active Handling
The second year of the C5 saw the Corvette lineup expand with the highly anticipated convertible model becoming available. This provided open-top driving enjoyment to the Corvette experience. Another significant advancement introduced late in the 1998 model year was Active Handling, a sophisticated stability control system. This feature significantly improved vehicle control and safety, especially in challenging driving situations. Visually, a subtle but distinguishing feature of the 1998 Corvette (and potentially late 1997 models) is the design of the two slots on the front fascia. These slots curve towards the rear at the bottom, a detail that differentiates them from subsequent years where the slots are straight down.

1999: Refinements and the Fixed Roof Coupe (FRC)
The 1999 model year brought further refinements and a new body style to the Corvette range. Fuel injector size was adjusted to 26# from 28#, and the fuel pump was revised to operate more quietly. The introduction of the Fixed Roof Coupe (FRC), also known as the hardtop, provided a more rigid and lighter option. All FRC models were equipped with the MN6 6-speed manual transmission and the Z51 suspension package, and they were approximately 60 pounds lighter than the standard coupe. Inside, the Head-Up Display (HUD) was introduced as a new feature, initially displaying a single line on the driver’s side fuel rail cover. A power telescoping steering wheel became an available option, and steering hardware was modified to address “wandering” issues. Door sill trim plates were also added for enhanced aesthetics and protection.

2000: Millennium Yellow and Enhanced Features
The dawn of the new millennium brought the striking Millennium Yellow exterior color option to the Corvette palette. Wheel design also saw a change, with the “Thin Spoke” design becoming standard, replacing the previous “wagon wheel” style. For California models, pup cats (secondary catalytic converters) were added to meet Low Emission Vehicle (LEV) standards, resulting in a slight 5 horsepower reduction compared to 1997-1999 models. Z51 equipped cars benefited from steel sway bar end links instead of plastic, and the sway bar diameters themselves were increased for improved handling. Notably, the rear sway bar diameter on the Z51 now matched that of the Z06. Other detail changes included the removal of the keyhole on the passenger side door handle and the addition of a passenger airbag ‘off’ switch on the center console.

2001: Performance Boost and the Z06 Arrives
2001 was a year of significant performance enhancements and the highly anticipated introduction of the Z06 model. Injectors reverted back to 28# for all models, and Second Generation Active Handling was introduced, further refining the stability control system. Nassau Blue was discontinued as an exterior color. An alternator ‘clutch’ pulley was added to automatic transmission (A4) cars for smoother operation. New soundproofing and foam were incorporated throughout all models, and convertible models received changes in thickness and material. Chrome exhaust tips became standard on coupes and convertibles. The Mass Air Flow (MAF) sensor was upgraded to an 85mm unit with an integrated temperature sensor, replacing the previous 74mm unit with a separate plug. The LS1 camshaft profile was revised, resulting in increased horsepower and torque figures: 350 HP at 5200 RPM and 375 lb-ft of torque at 4400 RPM for manual transmission (MN6) models. All Corvettes now featured the LS6 intake manifold and the LS6 engine block, which included windage passages and a beefier oil pump. The hardtop/FRC model was discontinued in favor of the new Z06. Pup cats were added to all models to meet emissions standards across the board. Stronger synchros were implemented in all transmissions, and exhaust manifolds were revised, regaining the previously lost 5 horsepower. The torque tube material changed from metal-matrix composite to aluminum alloy, and its diameter increased for greater strength. Driveshaft couplings were also upgraded on manual-equipped models.
The highlight of 2001 was the launch of the Z06, a high-performance variant designed for track capability. The Z06 featured a unique hardtop body style, rear brake ducting, screened inlets on the front fascia without fog lights, and F1 supercar tires. It boasted a more powerful LS6 engine with upgraded components, producing 385 horsepower. The Z06 also received the M12 transmission with shorter gearing, a titanium exhaust system, lightweight windshield, stronger clutch, stronger rear differential, red brake calipers, and a unique instrument cluster. The FE4 Z06 suspension included uprated springs, bars, and shocks, completing the transformation into a track-focused machine.

2002: Z06 Power Increase and Feature Enhancements
Building on the success of the Z06, the 2002 model year brought further enhancements to this performance icon. The Z06’s LS6 camshaft was revised again, along with a less restrictive intake airbox lid and descreened MAF, resulting in a power increase to 405 horsepower. Pup cats were removed from the Z06, contributing to the power gain. Z06 shocks were revised for better launch characteristics, and brake pads were upgraded for improved stopping power. Lighter, sodium-filled valves and stronger valve springs were implemented in the Z06 engine, along with higher tension rings and a slight piston redesign to address potential oil burning issues. Clutch strength was further upgraded. The Head-Up Display (HUD) became available on the Z06 model. The wheel supplier changed to Speedline, and the Z06 wheels transitioned from forged to cast construction, with minimal weight difference. Electron Blue was introduced as a new exterior color option. Steel end links were changed to aluminum on all models, and automatic transmission cars received an aluminum cooler case. An AM/FM stereo with an in-dash CD player became standard on Coupe and Convertible models, while AM/FM/Cassette was only available with the optional 12-disc CD changer.

2003: 50th Anniversary Edition and Fuel System Update
The 2003 model year marked the 50th anniversary of the Corvette, celebrated with a special Anniversary Edition. This edition featured a unique Anniversary Red paint and special badging and trim. Late in the model year, a new fuel system design, derived from the upcoming C6 Corvette, was implemented. This update was a significant, albeit running change, setting the stage for the next generation.

The final year of the C5 generation, 2004, saw the introduction of the Commemorative Edition, paying tribute to Corvette’s racing heritage and final production run. The Commemorative Edition featured a special Le Mans Blue paint scheme and unique badging. The CE Z06 model further distinguished itself with a carbon fiber hood and a unique decal package. Z06 shocks were further refined, along with accompanying changes to the upper front control arm bushing and rear sway bar bushing, representing the culmination of C5 chassis development. The 2004 model year concluded the successful run of the C5 Corvette, paving the way for the next chapter in Corvette history.
