- Chevrolet is reportedly working on a new Corvette Grand Sport.
- The new Corvette will have a 6.7-liter V-8 engine.

- The Corvette Grand Sport is expected in 2027.
General Motors is spending loads of money on the sixth-generation small-block V-8 engine. That new motor will power a variety of vehicles, including the Chevrolet Corvette. It should also come in two sizes, which means the company’s popular sports car could get an even bigger engine.
According to a new Corvette Blogger The report, citing information from GM’s parts book and “a person close” to the automaker, will have a 6.7-liter displacement-409 cubic inch engine in the sixth-generation LS6. This new engine will likely be the upcoming 2027 Corvette Grand Sport.
The report shared an image from the parts book that labeled the engine as aluminum with overhead valves and direct and port fuel injection. Previous rumors suggested that GM would use a smaller engine, a new 5.7-liter unit, in vehicles like the Chevrolet Silverado 1500.
The larger engine will reportedly power the Corvette, which GM will develop for power and performance. We’ll also likely see the 6.7-liter V-8 power a future version of the Cadillac CT5. The CT5-V Blacking is a performance monster that could use a bigger engine and more power.
Popular small block
GM introduced the fifth-generation small-block V-8 in 2013. The sixth-generation engine will begin arriving in GM’s full-size pickups starting in 2027 before making its way to other models. In 2023, GM announced it would invest $579 million in its Flint engine operations to build a sixth-generation V-8, and earlier this year, the company put in even more.
GM is promising that the new engines will deliver more power than the current lineup. The current 5.3-liter V-8 makes 355 horsepower and 383 pound-feet of torque. The larger 6.2-liter engine produces 420 HP and 460 lb-ft, with the supercharged version maxing out at 682 HP and 653 lb-ft.
According to the automaker, the increase in power will not compromise performance. It’s also unclear whether GM will pair the engine with any form of electric power. While the automaker is pulling back on some of its electric vehicle efforts, hybrids are only growing in popularity, and we expect some vehicles to be electrified.
