IN the game of awesome motoring nomenclature, American tuner Hennessey just claimed top spot thanks to its new Exorcist Camaro.

Built to take part in a holy horsepower war with Dodges upcoming Demon, the Camaro-based Exorcist packs a 745kW punch.

The Hennessey team have fettled with the 6.2-litre supercharged LT4 V8 under the bonnet (which comes from the factory with 477kW), until it is a tyre-frying warrior for the gods of burnouts.

They also ported the cylinder heads, upgraded the camshafts, added long tube stainless steel headers, and let the Camaro breathe deeper thanks to a freer-flowing induction system. It’s all controlled through a re-flashed ECU.

Gearbox options are limited to either a six-speed manual, or ten-speed automatic. However, those unwilling to work 745kW with three pedals will have to fork out $13k for a transmission upgrade so the auto can handle the extra oomph.

If you already have a ZL1 in your garage the Exorcist upgrades will cost $72,655, but Hennessy offers pre-built cars for $157,199.

To quote one Ace Ventura, “I have exorcised the demons!”
