It was a matter of time before some lucky owner of the new 2023 Chevrolet Corvette Z06upload your sports car to a power bank to check how many of the declared 679 horsepower actually reach the rear wheels. The Speed Demon YouTube channel has been in charge of doing it.
It should be remembered, before clicking ‘play’, that the Chevrolet Corvette Z06 is powered by an LT6 engine. We talk about a 5.5-liter naturally aspirated V8 that, without supercharging, develops 679 horsepower at 8,400 rpm and has a maximum torque of 623 Nm at 6,300 rpm; Its injection cutoff is at 8,600 rpm. To this must be added lubrication by dry sump and flat-plane crankshaft.
The Chevrolet Corvette Z06 on the dyno
The Chevrolet Corvette Z06 that stars in the video belongs to a client, so it is quite representative for future buyers: we anticipate that powertrain loss is well below usual figures, which usually range between 15 and 20%.
On the first try, the Chevrolet Corvette Z06 produced 597 bhp at 8,380 rpm and 572 Nm at 6,360 rpm, while on the second the figures were slightly higher: 608 bhp at 8,490 rpm and 574 Nm at 6,360 rpm. The third was undoubtedly the definitive one: 618.5 hp at 8,400 rpm and 569.5 Nm at 6,200 rpm. All this reveals that the powertrain loss is 9%.
In front of Lamborghini and Ferrari
The context to be able to compare the figures of the Chevrolet Corvette Z06 is provided by the owners of the power bank, Phenom Autos. When they went up the Lamborghini Huracan, delivered 500 hp. The Lamborghini Huracán LP 580-2, for its part, reached 578.9 CV while the Lamborghini Huracán Tecnica and the Lamborghini Huracán STO reached 639.8 CV.
It does not end there. For Phenom Autos passed a Ferrari 458 which yielded the following figures: 425.8 hp and 431.2 Nm. Remember that the Chevrolet Corvette Z06 costs half the price of the equivalent Ferrari or Lamborghini. The only vehicle that has improved the figures of the American model has been a BMW M4 CSL that delivered 613.4 CV and 720 Nm.
So far, we are looking at the most powerful and purist Chevrolet Corvette: it is not surprising that they say that It might be the best sports car made in America. At the moment, its V8 has won the game over a 90º atmospheric V8 (Ferrari) and a 90º atmospheric V10 (Lamborghini). And with a considerable margin.
