Texan tuner Hennessey Performance has a big love for German sports cars, especially products of AMG. The latest car of the Affalterbach-based company they have modified and equipped with their HPE600 kit is the Hennessey Mercedes AMG GT. Here the car is shown during dyno tests.

Hennessey Mercedes AMG GT HPE600 sounds like a freakin’ jet on the dyno, flaunting its 600 horsepower output. But this is only stage one of what HPE is capable of extracting from the 4.0 liter bi-turbo V8. More powerful packages are yet to come.

The HPE600 package for Hennessey Mercedes AMG GT result in a gain of 80 horsepower over the standard 510. But that’s real-wheel horsepower. It’s the power that’s put to the ground. The nominal power output of this car at the crank is way above 600 hp.
