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.

Ferrari looks to cut 20% total C02 emissions over 7 years

In the late 1970s, performance cars suffered a huge blow when the necessity for better economy and lower emissions crippled their power. It took nearly a decade for the horsepower to return. Today, we're in the middle of another push for greater vehicle efficiency, but don't expect another era of malaise this time. Instead, lightweight materials, turbos and hybrids mean that everyone can be happy. However, the pressure to clean up isn't just for the mass market, supercars must improve too, but Ferrari at least seems to be taking on the challenge in stride.
Ferrari Powertrain Director Vittorio Dini recently told Automotive News Europe that the Prancing Horse will improve its current average C02 emissions of 270 grams per kilometer by 20 percent by 2021, to reach about 216 grams of C02 per kilometer. To achieve these lofty ambitions, the company will exploit a relatively simple path. "In the future, all of our V8s will use turbos," said Dini said to ANE. Also, its V12s will use hybridization because it'll be a better choice for them compared to the heat of multiple turbos, he claimed.
The first steps of this strategy are already in front of us. The new California T ditches its naturally aspirated V8 in favor of a smaller displacement, more powerful turbocharged unit, and the LaFerrari is already using the hybrid V12. Dini's quote certainly lends some credence to the rumor that the 2015 refresh for the 458 Italia may use an even more powerful version of the California's turbo V8. With a new Ferrari model planned for each year between now and 2018, the Prancing Horse seems unperturbed by any threats posed by emissions.

Motor Trend hits Laguna Seca with Ferrari F12, Chevy Corvette, Porsche 911

According to the crew at Motor Trend, we should think of the video below "as an addendum to Best Driver's Car," a test the magazine put together that elevated the 2013 Porsche 911 Carrera 4S above all others in the category of driving joy. It seems the brand-new 2014 Chevy Corvette Stingray wasn't able to take part in the magazine's official test, and neither was the Ferrari F12 Berlinetta.
And so Motor Trend did the only logical thing: It procured both the 'Vette and Prancing Horse as soon as it could, and put them both on track with the Driver's Car-winning 911. Of course, these cars don't actually compete against each other - the Ferrari offers up 731 horsepower and wears an asking price of $434,144 as tested, which means you could buy four loaded Corvettes for the price of one F12, and still have money left for a garage to store them in - but that's not the point of this particular test.
The point of this test isn't to listen to the beautiful sounds coming from the Porsche's flat-six-cylinder, the Corvette's pushrod V8 or the Ferrari's luscious V12, either, but the video below is worth watching for those three reasons alone. You know what to do.
