Hennessey twin-turbo Ferrari 458 boasts 738 hp, 0-60 in 2.8 seconds

Hennessey Performance Engineering, hot off the heels of its Bugatti Veyron-crushing Venom GT, set its sights on modifying one of the finer Ferrari models. The resulting HPE700 Twin Turbo 458 is a badder, faster 458 Italia with a twin-turbo upgrade that adds 168 horsepower to the already potent 4.5-liter V8. That's 738 hp, which, paired with the extra 134 pound-feet of torque, for a total of 532 lb-ft, is good for a 2.8-second 0-60 run.
Low-inertia ball-bearing turbochargers are used to boost the power, and an air-to-water intercooler makes sure the air surging into the combustion chambers is as cool and dense as possible. Twin wastegates and blow-off valves relieve extra boost pressure and, in addition to a new stainless-steel exhaust system, add some new noises to the 458's soundtrack. The V8 is boosted to a relatively mild 7 psi maximum and maintains 6 psi on its way up to redline. A reflash of the engine control unit brings the package together. HPE is confident enough about its wares that the $59,995 upgrade also comes with a one-year/12,000-mile warranty.
The HPE700 Twin Turbo 458 is set to be unveiled on Friday at the Concorso Italiano located at the Laguna Seca Golf Ranch, which is part of California's Monterey Car Week festivities. It also can be viewed on Saturday in the paddock at Mazda Raceway Laguna Seca for the Monterey Historics Rolex Monterey Motorsports Reunion vintage car races. Check out the press release below for the full details, as well as a video of the Ferrari in action.

Race Recap: 2014 British F1 Grand Prix readjusts the balance of power

Qualifying for the British Formula One Grand Prix was just as much a surprise for fans as it was for teams. Certain team weather radar displays didn't accurately pinpoint storm systems over the track, and in the case of at least two teams, the lack of data was compounded by poor decision making. That's how both Ferraris and both Williams got kicked out of qualifying in Q3 - the drivers already on track took advantage of a dry spell between rains, but Ferrari and Williams waited too long to get back out, and by the time they did it had started raining again.
Rain-induced bewilderment hit the front of the field as well. When all appeared resolved in Q3 but the clock hadn't yet run down to zero, drivers including Lewis Hamilton and Daniel Ricciardo pulled into the pits thinking the day was done. However, a drying last sector of the Silverstone circuit meant the drivers still out could suddenly improve their times by four seconds in just that sector. When the bell tolled, those who fought to the last were those who lined up first: Nico Rosberg in the first Mercedes AMG Petronas, Sebastian Vettel in the first Infiniti Red Bull Racing, Jenson Button in the McLaren, Nico Hülkenberg in the first Force India and Kevin Magnussen in the second McLaren.
Hamilton had fallen all the way to sixth on the grid, a mortifying blow to his race and his championship challenge. He was followed by Sergio Perez in the second Force India, Ricciardo in the second Infiniti Red Bull Racing, Toro Rosso teammates Daniil Kvyat and Jean-Eric Vergne completing the top ten.

Mansory Stallone makes a man out of Ferrari F12

The Mansory Stallone you see above isn't the first such transmogrification of a Prancing Horse. This one is based on the Ferrari F12 Berlinetta, but the first honor, as far as we can tell, went to the Stallone based on the 599 GTB Fiorano. The F12 version was unveiled at the Geneva Motor Show this year, but we missed out, and we were sure you wouldn't want to miss it.
As with its predecessor, this one gets a total makeover, from the new front clip and hood to the side skirts, new rear end, rear diffuser and rear wing. There is additional muscle for the 6.0-liter V12, too - a tweaked ECU and sports exhaust with a stainless steel muffler getting matters up from 740 horsepower to 775, and torque from 509 pound-feet to 535. Moving things forward is a set of bespoke, staggered, lightweight aluminum wheels, 21 inches up front, 22 in the back.
The showstopper is inside, where a red and black leather treatment and redesigned steering wheel will make the cabin a very intense place to be. Check out the press release below for the minutiae, and the high-res gallery above for more angles.
