Porsche 911 Turbo

The Porsche 911 Turbo production sports car consumes up to 16 per cent less fuel than its predecessor, develops 20 bhp more power, delivers 30 Nm/22 lb-ft more torque, and accelerates up to 8 per cent faster on a reduction in weight of up to 25 kg or 55 lb – not to mention the enhanced driving dynamics offered by the car.

Given these qualities, the 911 range stands out even more clearly than before from its competitors particularly in terms of efficiency and acceleration. The main specifications (different figures for the Cabriolet where appropriate in brackets) are as follows:

3.8-litre six-cylinder biturbo horizontally-opposed power unit developing 500 bhp (368 kW);
six-speed manual gearbox, optional seven-speed PDK Porsche-Doppelkupplungsgetriebe;
active PTM Porsche Traction Management all-wheel drive;
acceleration 0 – 100 km/h in 3.7 (3.8) seconds, with PDK and the Sport Chrono Package Turbo in 3.4 (3.5) seconds;
top speed 312 km/h (193 mph);
fuel consumption in the NEDC 11.6 (11.7) ltr/100 km equal to 24.3/24.1 mpg imp, with PDK 11.4 (11.5) ltr/100 km (equal to 24.8/24.6 mpg imp).

The heart and highlight of the Porsche Turbo is of course the power unit displacing 3.8 instead of 3.6 litres. This engine for the first time developed brand-new from the ground up in the 35-year history of the 911 Turbo comes with Direct Fuel Injection, an efficiency-enhancing expansion-type intake manifold, and a turbocharger exclusive to Porsche with variable turbine geometry (VTG) on a gasoline power unit. The result is not only an increase in output over the former model by 20 bhp to 500 bhp (368 kW), but also an increase in peak torque up by 30 Nm/22 lb-ft to 650 Nm/479 lb-ft.

The Porsche Turbo comes as standard with a six-speed manual gearbox. As an option the turbocharged power unit may for the first time be combined with the sevenspeed PDK Porsche-Doppelkupplungsgetriebe which, unlike Tiptronic S on the former model, also comes with a limited-slip differential.

The PDK double-clutch gearbox is a further development of the transmission already featured in the 911 Carrera with reinforced components. The combination of PDK, Direct Fuel Injection and turbocharging provides a new level of efficiency, agility, response and performance, the 911 Turbo with PDK and the Sport Chrono Package Turbo accelerating from a standstill to 100 km/h in just 3.4 seconds (Cabriolet 3.5 seconds) with the help of Launch Control.
