Hennessey’s Exorcist is a Camaro ZL1 with 746kW

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.
