If there's one thing the stock McLaren MP4-12C has in abundance it's power from the mid-mounted 3.8-liter twin-turbocharged V8 engine which is rated at 600PS (592HP) and 600Nm (442.5 lb-ft). However, Texas-based tuning firm Hennessey Performance begs to differ as it believes the MP4-12C could do with some additional horses under the hood – 200 of them, to be precise. The company's new HPE800 Twin Turbo package makes several changes to the eight-cylinder engine including, but not limited to, a titanium exhaust system and upgraded intercooler and air-intake systems that lift output to 800-horsepower.
The transmission also receives some engineering love while the MP4-12C HPE800 will ride on new alloys wrapped in Michelin rubber.
Hennessey pointed out that it won't touch the suspension and the brakes. "HPE does not plan to offer any kind of a suspension or brake system upgrade as the factory systems will be difficult to improve upon," the company said in a statement.
Finally, the package will include a CarbonAero ground effects kit that incorporates a new, center-positioned frontal air inlet with hood extractor, and available custom parts for the interior.
