Corvette: Secrets of the C5

The C5 joins past and present to deliver power and precision handling on the road. Learn about some of the C5's secrets here.

By Charlie Gaston - March 2, 2015

This article applies to the C5 Corvette (1997-2004).

The C5 Corvette is a sophisticated sports car with impressive aerodynamic characteristics, optimum traction and incredible response, especially during hard cornering. Manufactured for a solid ride on and off the track, the C5 offers a styling signature reminiscent of previous models. However, this sleek sports car has less in common with previous generations (as well as other sports cars currently on the automotive market) when it comes to horsepower, torque and acceleration. Thanks to an enhanced engine and sophisticated control system, the C5 delivers top speed, while maintaining control and stability.

Component Breakdown

5.7 Liter V8 SFI Engine

Standing for Sequential Fuel Injection, C5 was all electrically controlled here for fuel and timing. This cast aluminum engine boasts a high-performance overhead valve design, and while it may be known as an old school "pushrod design," there are many benefits to this. The engines are more compact, lighter, and offer a lower center of gravity since the camshaft is in the block versus an overhead cam engine design. All of this offers superior performance, and hydraulic lifters have impressive horsepower and torque numbers with low maintenance. Early model years (1997 to 2000) deliver 345 horsepower at 5,600 RPM and 350 foot-pounds of torque at 4,400 RPM, while late model years (2000 to 2004) deliver 350 horsepower at 5,600 RPM and 360 foot-pounds of torque at 4,400 RPM.

ABS with Four-wheel Discs

The C5 benefits most from a four-wheel disc brake system with standard anti-locking braking on all four wheels. Manufactured with large, vented brake rotors, and accounting for the chassis' incredibly low weight, the C5 delivers superior braking performance without issue.

Magna-Steer

Characterized for its effortless steering, the C5 comes standard with Magna-Steer, an advanced computer-controlled, speed-sensitive power steering system that delivers optimum precision and handling. Utilizing an advanced rack-and-pinion gearset (a mechanism that prompts early system response when starting a turn), the C5 delivers smooth turns without the need for excessive maneuvering.

Scheduled Maintenance

To keep the C5 in good working condition, follow regular service checks and scheduled maintenance:

  • 10,000 miles: Check the engine oil life monitor and have the air filter replaced, if necessary.
  • 20,000 miles: Check the engine oil life monitor and have the air filter replaced, if necessary.
  • 30,000 miles: Check the engine oil life monitor and have the air filter replaced, if necessary
  • 40,000 - 50,000 miles: Check the transmission fluid and filter and engine accessory drive belt.
  • 100,000 miles: Change the spark plugs and have a mechanic perform a complete check of the vehicle.

Common Questions

What kind of transmission comes standard on the C5?

The C5 coupe and convertible come standard with a six-speed manual transmission, the Tremec T56, with an available four-speed automatic transmission as well. The more hardcore hardtop (FRC) and Z06 models were only available with a manual transmission.

What is the MPG for the C5?

The C5 offers 17mpg in the city and 25mpg on the highway.

What are the dimensions of the tires?

The standard C5 features front wheel tires that measure 17 inches by 8.5 inches with a 245/45R17 tire, and rear wheels that measure 18 inches by 9.5 inches with a 275/40R18 tire. Z06 models featured a wider 17 inch by 9.5 inch front wheel with a 265/40R17 tire and an 18 inch by 10.5 inch rear wheel with a 295/35R18 tire.

Common Issues

A sophisticated vehicle marked by both similarities and differences to previous well-respected generations, the C5 benefits from a range of new technology that offers enhancements that make life on the road or track easy. While the C5 is not without problems, the majority of buyers report strong handling, great mileage and smooth acceleration.

The most common issues include exterior damage to the front spoiler due to rough handling (the vehicle sits low to the ground), a faulty steering wheel lock that prevents drivers from starting the vehicle, and a problematic LED dash. In the event of a faulty steering wheel lock, visit your local dealer for a replacement. A problematic LED dash, on the other hand, is an easier fix, costing just $300 to replace the module. This can be done at home using a few simple tools or through a dealer or mechanic.
