The 2027 Chevrolet Corvette Grand Sport is the revival of C8 mid-engine lineup, having naturally aspirated power with widebody design.
Grand Sport Legacy
The Corvette Grand Sport was first introduced in 1962-1963 as Zora Arkus-Duntov’s secret project. This featured lightweight aluminum bodies then they introduced C7 iterations which combined Stingray handling with Z06 power.
Engine Powertrain
The 2027 Chevrolet Corvette Grand Sport is likely to be powered by the 6.7-liter LS6 V8 with pushrod valvetrain. You can expect direct/port fuel injection, forged crankshaft, and aluminum construction making it produce power of around 525-600 horsepower.
This performance figure position it above Stingray’s 495 hp LT2 while staying lighter than forced-induction models like the ZR1. Also, there are rumors to keep manual transmission available as option.
Design Upgrades
Wider bodywork now has space for larger wheels and tires for enhanced grip. This will have Z15 RPO sales packages, Z16 appearance kits, and potential special editions. Their prototypes spotted with the Buick Tri-Shield emblems which pays tribute to the Grand Sport legacy.
Release Timeline
Trademark for “Corvette Grand Sport” was filed in the 2022 with leaks confirming that it could be released in mid-2026 as a 2027 year. Will be priced under $100,000 to undercut Z06.
Performance Outlook
This Grand Sport promises the “perfect Corvette” essence: high-revving NA V8, mid-engine poise, and superior weight distribution for road and track dominance. It reshapes the C8 range, filling the naturally aspirated performance void amid ZR1 extremes.
