2007 Porsche 911 Turbo Pictures, Specifications, Information

The sixth generation of the range-topping 911 model features a revolutionary 480-hp, twin-turbocharged, 3.6-liter boxer engine with the world’s first gasoline-engine application of variable turbine geometry (VTG), a redesigned all-wheel-drive system, and evolutionary styling.

The 997 911 Turbo’s engine 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. More notable is the engine’s torque curve, which has been bolstered and broadened by the variable turbine geometry system. 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 (0-100 km/h; 3.7 sec.). Equipped with the standard six-speed manual transmission, the new 911 Turbo reaches the same 60 mph mark in 3.7 seconds (0-100 km/h; 3.9 sec.). With either gearbox, the top track speed of the new 911 Turbo is 193 mph.

Much of the 911 Turbo’s improved performance can be attributed to the variable turbine geometry system, the first such system available on a turbocharged gasoline engine. The heart of the technology is adjustable guide blades, which can vary in angle to most effectively guide engine exhaust flow onto the turbocharger’s impeller wheel. The result is a system that provides the advantages of both a small and large turbocharger, improving flexibility and acceleration, particularly at low engine speeds.

To transfer this power to the road, the new 911 Turbo features a redesigned all-wheel-drive system, with an electronically controlled multi-disc clutch replacing the previous model’s viscous clutch. Porsche Traction Management (PTM) allows variable power distribution fore and aft, and depending on conditions, the system’s electronics constantly determine optimal torque distribution to ensure ideal traction. In use, PTM provides exceptional agility on winding roads, outstanding traction in inclement conditions, and impressive active safety even at higher speeds. Though powerful, the 911 Turbo’s PTM setup is one of the lightest all-wheel-drive systems on the market.

The new 911 Turbo’s accelerative performance is duly tempered by its brake system, which is comprised of six-piston monobloc calipers up front, and four-piston monobloc calipers at the rear. Brake disc diameter at all four corners has been increased 20mm, to 350mm (13.78 in.). Optional is Porsche’s Ceramic Composite Brake system (PCCB). In addition to the exotic pad and rotor material, the PCCB option provides an increased front disc diameter (380mm /14.96 in.), absolute corrosion resistance, improved fade stability, and a 37-pound unsprung-weight savings versus the standard brake system.
