If you didn’t already think the new McLaren MP4-12C was quick enough then there is now a range of updates that can be fitted to improve speed and performance further. John Hennessey, the founder and president, of Hennessey Performance (HPE), which is a supercar tuning company based in Texas, has announced that the upgrades that can be fitted to the McLaren will take power up to over 800bhp.
The original MP4-12C already comes with a quite astounding 592bhp and some very clever Formula 1 derived technology, and while upgrades to further improve performance are all well and good, my reservation is that the balance and poise of the original MP4-12C would become upset by the extra power and performance.
Furthermore, McLaren are famed for their perfectionist approach to engineering and, well, just about everything they do to be honest, and so we can be sure that their brainchild, the MP4-12C, will have been built within very specific constraints and to very specific and particular requirements. One wonders whether McLaren would be particularly happy with another company modifying the performance of the car.
Nevertheless, the HPE tuned McLaren features a larger air-intake, intercooler system and improved turbochargers. There is also a custom-built titanium exhaust. Whether HPE will have played with the onboard computer we are unaware, however ECU remapping on the McLaren may indeed be necessary with such a jump in power.
Furthermore, HPE have modified the aerodynamic package as it has been designed to increase downforce. HPE have also stated that they will not be changing the suspension or the brakes as they have claimed that they would not be able to improve on the factory fitted components.
John Hennessey has been commenting the McLaren: “We’ve been taking fast cars and have been making them faster for over twenty years. I spent a lot of time around the new 12C at the 2011 Goodwood Festival of Speed and was very impressed. We’re excited to have the opportunity to take a great car and give it our own special performance touch while giving 12C owners a uniquely aggressive appearance.”
The modifications are sure to be popular amongst the lucky people that own an MP4-12C; it would however be interesting to see what McLaren themselves think of the new upgrade package offered by HPE.
