Porsche 911 Turbo
The sixth generation of the range-topping 911 model features a revolutionary 480-hp, twin-turbocharged, 3.6-liter boxer engine. It produces 480 hp at 6,000 rpm, 60 hp more than its predecessor, raising specific output of the 3.6-liter boxer-Six to an all-time high of 133 hp per liter and broadening its torque curve.
Peak torque rises to 457 lb-ft (previously 415 lb-ft), but that peak now spans an extended rpm range from 1,950 to 5,000 rpm, compared to 2,700--4,600 rpm in the previous 911 Turbo . Additionally, a function in the optional Sport Chrono Package allows a 10-second, mid-rpm-range ‘overboost', temporarily increasing turbo boost under full throttle by 2.9 psi, and swelling peak torque to 502 lb-ft.
A 911 Turbo equipped with the optional 5-speed Tiptronic S automatic transmission requires only 3.4 seconds to sprint from 0 to 60 mph. Equipped with the standard six-speed manual transmission, the new 911 Turbo reaches the same 60 mph mark in 3.7 seconds. With either gearbox, the top track speed of the new 911 Turbo is 193 mph.
