Tuning McLaren MP4-12C into twin-turbo HPE800

Tuning McLaren MP4 12C into twin turbo HPE800
When McLaren released the MP4-12C, there were some questions about the distinctiveness of its styling, but not about whether the engineers at Woking had extracted every bit of performance they could from its 3.8-liter twin-turbo V8 engine. John Hennessey and company, however, think they can do better. That’s why Hennessey Performance Engineering has targeted the 12C for its latest tuning package.

Traditionally, Hennessey usually starts by bolting on a pair of turbos to whatever car it can get its hands on. But McLaren has already done that, so Hennessey has fitted new ones, and along with it, upgraded the intercooler, intake, exhaust, electronic control modules and transmission. It’s also fitted a CarbonAero body kit, new wheels with Michelin Pilot Super Sport rubber and a redone interior swathed in carbon, leather and Alcantara.

The result is 800 horsepower, up from 592 stock. What Hennessey hasn’t touched, however, are the MP4-12C’s suspension and brakes, which the Texas-based tuner didn’t feel it could improve upon. Whether the rest is advisable is up for debate, but that’s never stopped the Texas tuner before, so check out the details in the press release after the jump and the renderings for a closer look at what to expect should any McLaren owners inexplicably feel their 12C is just too slow.

BMW M goes diesel – M550d, X5 M50d, X6 M50d

BMW M goes diesel M550d, X5 M50d, X6 M50d

The new M models come in the form of the M550d xDrive sedan, M550d xDrive touring, X5 M50d and X6 M50d. Each makes use of a 3.0-liter inline-six common-rail diesel with the aforementioned trio of turbos specifically developed for the M Performance range. Output is rated at 376 horsepower at 4,000 rpm and 545 pound-feet of torque available from 2,000 to 3,000 revs. If you’re keeping track at home, that’s a bump of 80 hp and 103 lb-ft over the 535d and 74 hp and 103 lb-ft more than the 3.0-liter mill fitted to the diesel X5 and X6.

Each model comes equipped with an eight-speed automatic gearbox and standard xDrive AWD, allowing the M550d sedan to hit 60 mph in 4.6 seconds – just four tenths of a second off the all-new M5′s 0-60 run. You read that right. The M550d Touring hits 60 in 4.9 seconds, with the X5 M50d and X6 M50d passing the mark in 5.4 and 5.3 seconds, respectively. All models are limited to 155 mph and fuel consumption ranges between 6.4 liters/100km and 7.7 liters/100km.

Audi R8 Limo

The vehicle is reportedly tipped to be completed by this coming summer, and will retain the donor car’s 5.2-liter V10 – but we’d guess not its all-wheel drive system, and none of its handling dynamics.
