2014 6.2L V8 VVT DI LT1 Corvette

Earlier in the week, leaked brochures suggested that the 2014 Corvette C7 Stingray was to have 455 hp and 625 Nm of torque running off the new LT1 6.2 litre V8 in its coupe form, up from the estimated 450 hp and 610 Nm bandied about when the car was first announced.

Turns out the numbers are correct – Chevy has announced that the LT1 is SAE-certified at those numbers with the standard exhaust system, and with an available performance exhaust system in tow, it’s 460 hp at 6,000 rpm and 630 Nm at 4,600 rpm, again SAE-certified. Like a proud parent, the automaker has come up with a report card, in chart form.


At 74 hp per litre, the LT1 has greater power density than the C6 Corvette’s LS3 6.2 litre engine and even the C6 Z06’s racing-derived 7.0 litre LS7. Indeed, the LT1’s torque is comparable to the LS7 up to 4,700 rpm. The company estimates that the C7 will do the century sprint in less than four seconds.

The LT1, a fifth-generation iteration of the Small Block engine family that debuted in the Corvette in 1955, incorporates a new cylinder-head design and a new, sculpted piston design, as well as a high-flow, four-into-one exhaust manifold based on the design of the LS7 engine. The unit features direct injection, Active Fuel Management (or cylinder deactivation, if you will) and continuously variable valve timing.
