2007 Porsche 911 Turbo

(from Porsche Press Release)  THE PORSCHE® 911® TURBO—NOW IN ITS SIXTH ITERATION—IS THE MOST POTENT AND CAPABLE YET

Twin-turbocharged 2007 911 Turbo with variable turbine geometry (VTG) and electronically controlled all-wheel-drive is an everyday supercar

The sixth generation of the range-topping 911 model provides towering performance in a practical, stylish and functional package suitable for everyday use. Power comes from a revolutionary, 480-horsepower, twin turbocharged, 3.6-liter boxer engine featuring Porsche’s first application of variable turbine geometry (VTG).

The new 911 Turbo also offers a redesigned, electronically controlled all-wheel-drive system, and evolutionary styling.

The highlights of this impressive new model include:

Variable Turbine Geometry (VTG)

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.

New all-wheel-drive system management

Benefiting from a newly developed all-wheel-drive management system, the 911 Turbo is able to convert the enormous power of the engine into practical performance on the road with optimum traction in all conditions. The standard Porsche Traction Management (PTM) system features an electromagnetically controlled multiple-plate clutch for distribution of power front-to-rear. Responding within 100-milliseconds to both driver input and road conditions, PTM is able to immediately transmit more power to the wheels that can use it best whenever required.

Quick with the six-speed manual transmission, even quicker with the 5-speed Tiptronic® S

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.

Extra boost: Sports Chrono Package Turbo with Overboost

For the first time the optional Sports Chrono Package Turbo provides a brief Overboost of power. With the Sport button engaged, and under full throttle during mid-range engine speeds, turbocharger boost pressure is temporarily increased, boosting torque by 45 lb-ft (60 Nm) to a staggering 505 lb-ft (680 Nm). This Overboost is an advantage in short, interim acceleration and overtaking maneuvers.

Active suspension is standard equipment

The 2007 911 Turbo arrives standard with Porsche Active Suspension Management (PASM), giving the driver the choice of either a sporting but comfortable standard set-up (Normal mode) or a particularly sporting and firmer set-up (Sports mode).

Upgraded braking system

The 2007 911 Turbo features a brake system even more efficient than on the former model. The brake concept on the front wheels has been carried over from the Carrera® GT, with six-piston brake calipers in conjunction with 350mm (13.78") brake discs ensuring impressive stopping power. The new brake configuration also feeds more brake power to the rear wheels, where four-piston brake calipers again interact with brake discs measuring 350mm in diameter. Two other features are pre-loading of the brake system and Brake Assistant, both serving to shorten stopping distances even further when applying the brakes suddenly. The new 911 Turbo is also available as an option with Porsche Ceramic Composite Brakes (PCCB® ) for truly outstanding braking qualities ensured by ceramic brake discs, and further developed in even larger dimensions than before.

5-speed Tiptronic S automatic with new dynamic driving functions

Whenever the driver takes his foot off the gas pedal abruptly, the new Fast-Off function prevents the Tiptronic S transmission from upshifting, even if the driver does not release the gas pedal completely. This improves driving dynamics, particularly on winding or serpentine roads and. The new Fast-Back function enables the driver to downshift more quickly when applying the brakes in a sporting style, when moving over quickly from the accelerator to the brake pedal. When braking into a bend, for example, Fast-Back automatically helps select the proper gear for subsequently accelerating out of the bend.

High standard of passive safety

Like the entire 911 model series, the new top-of-the-range 911 Turbo offers a high standard of passive safety.  Apart from full-size airbags for the driver and front passenger, the entire range of six airbags includes two head airbags in the side window sills interacting in a side-on collision with thorax airbags in the front seat backrests.  Porsche was the first manufacturer to offer this additional safety benefit.

Reversing the weight spiral 

Despite the change in dimensions and new functions, the new 911 Turbo is lighter than its predecessor – a benefit aided by the doors made completely of aluminum. Weighing just 11 kg (24 lb.), the doors, together with other lightweight features, help to give the car a DIN unladen weight of 3495 pounds (1585 kg). Despite a wider range of equipment, this is 11 pounds (5 kg) lighter than its predecessor, and the power-to-weight ratio, in turn, is an outstanding 7.28 pounds per horsepower.
