Hennessey

Texas-based tuning company Hennessey has begun testing of its aptly-named Exorcist – a modified Chevrolet Camaro ZL1 designed to compete with the Dodge Charger SRT Demon. Thanks to extensive engine modifications to the standard Camaro ZL1's 6.2-litre supercharged V8 – including a larger supercharger, camshaft and cooling cores, a beefed-up valvetrain and freer-flowing intake system – the Exorcist produces a claimed 746kW and 1197Nm.

Hennessey Performance has picked up the gauntlet laid down by the Dodge Demon, outrunning the factory-fresh Fiat Chrysler dragster in a Camaro called 'The Exorcist'. Based on a Chevrolet Camaro ZL1, The Exorcist has been boosted to 756kW and 1197Nm. The results are predictably impressive. The hotted-up Chevy ran a 2.1-second 0-60mph (0-97km/h) sprint, pulled to 100mph (161km/h) in 4.7 seconds and ran the quarter mile in 9.57 seconds at 236km/h.

Hennessey Performance has provided a further peek at the upcoming Venom F5, ahead of its debut at SEMA next week. Named after the most lethal category of tornado, the Venom F5 has been set the task of outdoing the bonkers Venom GT, which has a verified 435 km/h top speed.

The Hennessey Venom GT has set a new world record to become the quickest street-legal production car ever to make the dash from 0-300km/h. With Guinness World Records officials and VBox timing specialists on hand, the Venom GT set an official time of 13.63 seconds for the stratospheric sprint – the average of two runs completed in opposite directions along the runway at Ellington Airport in Texas (the first 13.18sec with a 6.5km/h tailwind, the second 14.08sec with a 9.7km/h headwind).
