The debut of the mid-engine Corvette is rapidly approaching, and while we expect the complete details when the fresh Vette drops on July 18th, we do have the inside scoop on the C8’s engine a few days prior to the car’s reveal. According to sources familiar with future Chevrolet product plans, the new mid-engine C8 Corvette will be powered by GM’s upcoming 6.2L V8 engine assigned RPO Code LT2.
The 6.2L LT2 V8 is nearly identical to the 6.2L LT1 V8, which can be found in the current Corvette C7 Stingray and Grand Sport, as well as the Chevrolet Camaro SS and new Camaro LT1. However, the LT2 receives a few minor modifications that enable fitment in the mid-engine configuration of the Corvette C8. What’s more, the LT2 may also feature a few other improvements compared to the LT1.
GM Authority has heard of but has not been able to corroborate with a full degree of certainty updates to the Active Fuel Management system (enabled in the Eco driving mode) and valving improvements that diminish friction, delivering smoother and more efficient operation.
Other than that, the LT2 will have the same displacement of 6.2 liters (376 ci) as the LT1, along with the same OverHead Valve (OHV), or push-rod configuration. Supporting technologies will include Direct Injection, Variable Valve Timing, and Active Fuel Management.
Mounted in the mid-engine Corvette C8, the LT2 is expected to offer slightly higher output figures than offered by the LT1 in the C7, to the tune of 480 to 500 horsepower. For reference, the LT1 in the base-model C7 Corvette Stingray offers 376 cubic inches of displacement, with output rated at 455 horsepower at 6,000 rpm and 460 pound-feet of torque at 4,600 rpm. On the Z51 package and the Grand Sport, both of which come equipped with the NPP high-performance exhaust system, power rises slightly to 460 horsepower at 6,000 rpm and 465 pound-feet of torque at 4,600 rpm.
|Corvette C7 Stingray Base||Stingray C7 with Z51 Package||C7 Grand Sport||Expected C8|
|Displacement (liters / cubic-inches)||6.2 / 376||6.2 / 376||6.2 / 376||6.2 / 376|
|Power (hp / kW @ rpm)||455 / 339.3 @ 6000||460 / 621 @ 4600||460 / 621 @ 4600||480-500|
|Torque (lb-ft / Nm @ rpm)||460 / 343 @ 6000||465 / 627.8 @ 4600||465 / 627.8 @ 4600||480|
The LT2 in the mid-engine Corvette C8 will be mated to a seven-speed dual-clutch transmission. A grand total of zero sources have so far told GM Authority that a manual transmission option will be available.
The fact that Chevrolet will continue using the fifth-generation Small Block engine architecture for the mid-engine Corvette C8 shouldn’t come as a terrible surprise given how capable the engines are. The family was introduced by the aforementioned LT1 for car applications, as well as the 4.3L LV3 V6, 5.3L L83 V8, and 6.2L L86 V8 for pickup trucks.
Finally, we should note that the LT2 will only serve as the mid-engine Corvette C8, and other variants – especially those with more power – will arrive later.
