Hennessey Performance has arranged for a quarter-mile showdown between a standard Chevrolet Corvette Z06 and a tuned Cadillac CT5-V Blackwing. Here’s what the contenders brought to the start line.

Starting with the Corvette, it packs a 5.5-liter naturally aspirated V8 with 670 PS (661 hp / 493 kW) and sprints 0-97 km/h (0-60 mph) in 2.6 seconds.

For its own part, the Cadillac makes do with a 6.2-liter V8 and 677 PS (668 hp / 498 kW) in its stock form, but the example in the video received a power-up to 1,014 PS (1,000 hp / 746 kW) courtesy of an HPE1000 package.

The upgrade includes new cylinder headers and distribution shaft, a larger supercharger and many other aftermarket parts. The tuning company points out that its upgraded Cadillac sprints one-tenth of a second faster than the Corvette.
