Unique Helmholtz induction for new GM LT6 V8

The 2023 Corvette Z06 recently arrived, powered by a 5.5-L LT6 V8 spinning a radical flat-plane crankshaft. Now that additional engineering details have emerged, the LT6's top hat has supplanted its crankshaft as this engine's most interesting feature. That topper - an active induction system - is capable of filling this DOHC V8 with the air needed to produce SAE-certified 670 hp (499 kW; 121.8 hp/L) at 8400 rpm without any kind of supercharging.

Let the record show that the LT6 is the most powerful naturally aspirated V8 ever produced. The 6.6-L 622-hp (94.2 hp/L) M159 engine energizing the Mercedes-Benz SLS AMG Black Series coupe has been bumped down to second place. While exemplary output qualifies the Z06 as a legitimate supercar, bountiful torque is what owners will most appreciate on the street.
