Nissan GT-R and Ferrari 458 Speciale in track battle by Evo

Supercar slayer. That's what they call the Nissan GT-R. And in many ways it is, even though its price and performance over the years have risen to put it squarely in supercar territory of its own right.
In fact, as Evo magazine has been compiling a list of its fastest cars - using the Anglesey Circuit in Wales as its common ground - the GT-R has came out on top... that is, until Evo tested the Ferrari 458 Speciale. The two are about as different as you can get within the supercar segment: one has a turbo six up front driving all four wheels in a 2+2 configuration, the other a mid-engined, rear-drive V8 two-seater. In fact the only common ground you're likely to find between them comes down to their two doors and dual-clutch transmissions. Though they serve it up in different ways, both are class-leading performers.
We're looking forward to watching Evo populate its leaderboard with more entries like the McLaren 650S and more potent Nismo GT-R, but in the meantime the British enthusiast magazine, by popular demand, has released side-by-side in-car footage of both supercars putting their best lap forward around the seaside circuit.

Glickenhaus' FIA championship-winning P4/5 Competizione comes home [w/video]

The sexy Ferrari P4/5 Competizione, a cross between the lightweight F430 Scuderia and the race-only F430 GT2 with special Pininfarina bodywork, spent some time in Europe notching a few race victories. But it finally has made its way back to the US and into owner Jim Glickenhaus' collection, where it met its sister car and inspiration, the original P4/5.
During its short-but-sweet two-year racing campaign, it competed in just two races but left a big impact. We'd call any lap of the Nürburgring that's under seven minutes a victory, but, with the help of a hybrid drivetrain, the P4/5C qualified for the 2012 Nürburgring 24 Hours with a lap of 6:51. That's faster than any Ferrari-powered vehicle has ever gone around the 'Ring. The car then went on to win the EXP-1 class (for experimental vehicles), for a World Championship, and finished the race 12th overall in a field of 170 cars. Not bad at all.
For those who haven't kept up on the P4/5C, the hybrid powertrain was introduced to the one-off racecar for 2012 after it had attempted the Nürburgring 24 Hours in 2011 with negligible results. A Ferrari 4.0-liter V8 was joined by a Formula One-style Kinetic Energy Recovery System (KERS), good for a combined 563 horsepower.

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.
