Chevrolet Corvette Stingray / Grand Sport / Z06 C7

HPDE Overview

The C7 is the most refined front-engine Corvette ever produced. The LT1 direct-injection V8 makes 455 hp with excellent fuel economy, and the Z06's LT4 supercharged V8 produces a staggering 650 hp. The 7-speed manual has a controversial automatic rev-match feature (disable it for development), and the 8-speed auto is surprisingly excellent on track. The C7 Grand Sport is widely considered the best track Corvette money can buy. It combines the Stingray's naturally aspirated LT1 with the Z06's wider body, bigger brakes, and aero package. At 455 hp and 3,360 lbs, the Grand Sport offers the perfect balance of power, handling, and reliability — without the Z06's supercharger heat management challenges. The C7 Z06 is brutally fast but has well-documented overheating issues. The supercharged LT4 generates enormous heat that the stock cooling system cannot manage during sustained track driving. Many Z06 owners have experienced significant power loss after 3-4 hard laps as the car goes into thermal protection mode.
