Hennessy

US-based tuning house Hennessey Performance Engineering will offer an engine upgrade for the McLaren 765LT supercar, allowing for a power increase of approximately 32 per cent. Known as the HPE1000 package, the upgrade comprises new air filters for the car's 4.0-litre twin-turbo V8, a re-mapped factory ECU calibration, a stainless-steel exhaust downpipe upgrade, high-flow exhaust componentry, and a chassis dyno calibration.

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.

People often say “don’t forget where you came from”. Although we’re focused on every new car, every last detail here at CarAdvice, we have an extensive back-catalogue of news stories, lifestyle yarns and reviews. Here’s a look at what happened on the week of April 10 in years past. Two years ago this week the Hennessey Venom GT Spyder sped all the way to 427.4km/h, surpassing the previous record set by the Bugatti Veyron Sport Vitesse by nearly 20km/h.

The Hennessey Venom GT is the world's fastest car after posting a top speed of 270.49 miles per hour - or 435.31km/h. The US-built, 928kW supercar - which is based on a Lotus Exige but is powered by a 7.0-litre twin-turbocharged V8 - managed the feat on the 5.18km runway the Kennedy Space Center in Florida, and the results were reportedly confirmed using a Racelogic Vbox satellite-based telemetry system.
