Hennessey Performance Engineering HPE1000

The name is similar but no, it’s not a product of that well known French Cognac House. But, like a good Cognac, this just announced new Hennessey is going to leave a slight nutiness on your palate.

Not as much nutiness as the US engineering firm’s Hennessey Venom GT Hypercar, with 1244hp, a world speed record among its boasting rights and a sound system designed by Steven Tyler of Aerosmith fame.

The HPE1000 is expected to exhibit a milder more rounded nutiness, one that will have a broader appeal and the sort that can only be achieved with a more sensible 1000hp and seating for five.

To create the HPE1000, Hennessey Performance Engineering started with a 2014 Chevrolet SS sedan (SS Commodore in Australia), and replaced the stock LS3 V8 with a 1000hp twin-turbo version of GM’s 427ci (7.0 litre) LSX engine.

Unlike the auto only (for now) stock Chevrolet SS, you can order your HPE1000 with a suitably ‘fortified’ 6-speed manual or automatic gearbox. Hennessey also upgrade the suspension, wheels and tyres to deal with the added oomph.

The interior receives some ‘custom upgrades’ and the stock-looking exterior features some CarbonAero body components.

We don’t know how fast it goes - expect a video of a quarter-mile run at some stage - but the lessor Hennessey HPE600 (600hp) version of the Chevrolet SS can manage a goodly 11.84 second time.

We don't know what it costs either but expect a substantial premium over the donor car.

As an aside the HPE600 number 1 car is on the market right now and could be yours for what seems (to an Australian) a very reasonable US$65,000.
