At the heart of the ZR1 Corvette resides the supercharged 6.2L LT5. GM’s engineering department was also tasked with producing the ZR1’s engine, which would have to perform at a higher level than that of the Z06’s supercharged LT4 small-block. The 755 HP supercharged LT5 would elevate the Corvette’s performance to a level never before achieved.
