American sports car tuner Hennessey Performance has released a monstrous version of the Holden Commodore-based Chevrolet SS with more power than the original Bugatti Veyron.

The Hennessey HPE1000 trades the Australian-made Chevrolet SS’s regular 310kW 6.2-litre LS3 V8 for a ballistic 746kW (1000hp) twin-turbocharged 7.0-litre LSX V8, humbling the first iteration of the Veyron by 10kW.

The HPE1000 also thumps the best efforts of local high-performance divisions Holden Special Vehicles and Walkinshaw Performance, including the 6.2-litre supercharged LSA V8-powered 430kW HSV GTS and the 497kW Walkinshaw W497.

The Hennessey-tuned Chevrolet SS features a long list of enhancements, including forged low-compression pistons, steel connecting rods and a Callies 4340 steel crank. Other major upgrades include new fuel system with new injectors, an air-to-air intercooler, high-flow air filter, stainless steel piping and exhaust, and a new engine management calibration.

Each Hennessey HPE1000 comes with unique exterior badging and individually numbered dash and engine plaques.

The tuner will also offer a range of optional performance and appearance enhancements including upgraded wheels and tyres, suspension and brakes, transmissions and drivelines, and headers and exhausts.

Hennessey is yet to release performance claims or pricing for the HPE1000.

Hennessey’s announcement comes just days after US publication Motor Trend reported the Chevrolet SS would soon be offered with a six-speed manual transmission and magnetic ride suspension.
