US tuner Hennessy teases new supercharged Chevrolet SS package with toll road test.

Holden's VF Commodore has already had the tuning wand waved over it locally by the likes of HSV, Walkinshaw Performance and Harrop Engineering, but the US-market Chevrolet SS version is about to score a similar treatment from the aftermarket maestros at Hennessey Performance.



Rather than making performance claims via simple press release, the US firm has showcased the upcoming package in the above video, where the boosted Chevy SS is used to test a new Texas freeway’s automated toll system under the supervision of a Texas Highway Patrol Dodge Challenger.

While the top speed of 262km/h is about what you could expect from a stock 6.2-litre SS, it’s fair to say the HSV GTS-trumping 600hp (448kW) output suggested by the HPE600 supercharger upgrade’s name will help it get it there a lot quicker.

Hennessy are you to specify any other details of its planned upgrades, but Motor Authority reports that high-flow induction and turbo systems, intercooler and exhaust packages, plus engine management tunes, brake and suspension upgrades are also in the works.
