LAs Best 2007 Porsche 911 Turbo For the first time, the power unit of the new Porsche 911 Turbo features an exhaust gas turbocharger with variable turbine geometry (VTG). VTG provides for efficient control of the exhaust gas flow throughout the entire range of engine speed, guiding the flow of air in exactly the right direction and at the right angle to the turbine blades. The result is yet another increase in engine output, despite engine capacity remaining unchanged at 3.6 liters, up from 420 horsepower to 480 horsepower. Maximum torque, in turn, is up from 415 lb.-ft. to 460 lb.-ft., and meaningful twist is on tap beginning at a low 1950 rpm. Equipped with a six-speed manual gearbox, the new 911 Turbo accelerates to 60 mph in only 3.7 seconds (0-100 km/h, 3.9 sec.). Equipped with the optional Tiptronic S, the car completes the same sprint in only 3.4 seconds (0-100 km/h, 3.7 sec.). This makes the new 911 Turbo the first sports car from Porsche with quicker acceleration with the automatic transmission than with the manual. This is the result of the interaction of the turbochargers with their variable turbine geometry, the Porsche Traction Management, and the new Tiptronic S set-up.
