here s what the 2027 corvette grand sport s 6 7l ls6 v8 sounds likeAmongst many other high-performance goodies, new Corvette Grand Sport debuts an all new LS6 engine generation for Chevy and we recently had the chance to catch up with this ultra-fast car for a hands-on preview.It gets a larger 95-mm throttle body and a tunnel ram intake as well as a very high 13:1 compression ratio. But perhaps the most important thing is more displacement, measuring 6.7-liters compared to 6.2-liter before. As a result it makes 535 naturally aspirated hp and 520 lb-ft of torque.Then again, maybe the most important thing is how it sounds. So give it a listen below.
