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.

LaFerrari 3D model adds depth to Maranello's new supercar

At its recent Geneva Motor Show unveiling, we couldn't help but spend a good long time gawking at the new LaFerrari supercar. It isn't just that it's the newest top-line Ferrari, or even that it picks up where the Enzo left off - it's just that there's so much to look at, from the ductwork in its long nose to the delicate artistry of its sideview mirrors. There's so much aerodynamic wizardry in play on every surface that you just want to pick it up in your hand and look underneath to take a closer look every which way - even underneath.
Sadly that's not possible, but we may just have the next best thing. Autoblog reader Giorgio has come up with this clever interactive 3D model of the LaFerrari, and we think it's neat enough that you might want to take a look - check it out by scrolling below. And don't forget - we love featuring what our car-crazed readers are up to, whether here or on our Facebook page, so keep those tips coming.

Ferrari 250 GT California could be your day off for $8 million

Vintage Ferraris consistently top the list of the most expensive cars ever sold. In private treaty sales, the 250 GTO is king, but even at public auctions, it's the horses that prance the highest. After the Mercedes W196 grand prix racer that set the world record this past July at nearly $30 million, the list of eight-figure sales is populated almost entirely by Ferraris: a 275 GTB/4 NART Spyder for $27.5 million, the pair of '57 Testa Rossas that sold separately a few years ago for $17 and $13 million apiece, the 250 LM recently went for over $14 million and the 250 GT SWB California Spider that sold in 2008 for $11 million.
Now RM Auctions has another California - this time a long-wheelbase model - on consignment for its upcoming sales in Arizona, where it is expected to fetch between $7 and $9 million. The 11th of only 50 made, chassis number 1055 GT features matching numbers, in red over black with those highly-coveted covered headlamps from the factory. It was delivered new in 1958 to Texas and was owned by some prominent Ferrari collectors and historians across the United States.
It underwent a comprehensive restoration in 1994 before taking the top prize in its class at the Cavallino Classic and has made the rounds of numerous other concours. It's spent the last few years in northern Europe and is now being put up for auction. "It is so choice," as our childhood friend Ferris would say. "If you have the means, I highly recommend picking one up." Check it out in the gallery of achingly gorgeous photos above and the details in the auction listing below.
