New 911 is techno whizz

IN the 40 years since the first prototype appeared, the place of the Porsche 911 Turbo at the technological summit

IN the 40 years since the first prototype appeared, the place of the Porsche 911 Turbo at the technological summit and peak of dynamic performance has never been in doubt.

Now, with the unveiling of the new “Type 991” generation 911 Turbo and Turbo S, the car’s reputation as a technology showcase combining the virtues of a circuit race car with those of an everyday road car reaches new heights.

New all-wheel drive running gear with active rear axle steering, adaptive aerodynamics, full-LED headlights and up to 560 hp from the flat six-cylinder twin-turbocharged engine emphatically underline the character of the 911 Turbo and Turbo S models.

Playing an equally crucial role is the entirely new, lightweight design chassis with a 100mm longer wheelbase riding on larger diameter 20in wheels.

The Porsche Dynamic Chassis Control (PDCC) active anti-roll system, which is offered for the first time on the 911 Turbo models, increases the dynamic performance potential even more. This system is standard equipment on the 911 Turbo S, together with the Sport Chrono Package Plus incorporating dynamic engine mounts, and Porsche Ceramic Composite Brakes (PCCB). These are also each available on the 911 Turbo.

As a consequence, the 911 Turbo S shortens the benchmark lap time around the Nürburgring-Nordschleife to well under 7 minutes 30 seconds — naturally on standard production tyres.

The standard “sound symposer” intensifies the driving experience further still, transmitting induction sounds of the turbo engine to the passenger compartment via a speaker diaphragm.

The performance partners in the powertrain are the further advanced engines and the new Porsche Traction Management (PTM) all-wheel drive system. The turbocharged 3.8-litre flat-six engine with direct petrol injection produces 520hp (383kW) in the 911 Turbo, and 560hp (412kW) in the Turbo S.

Porsche continues to be the only car maker to offer twin turbochargers with variable turbine geometry on a petrol engine.

Power is transferred to the drivetrain via a seven-speed dual-clutch transmission (PDK), which enables an auto start/stop function with engine shut-off that now activates earlier (when coasting to a halt) as well as the proven coasting function.

Together with a new thermal management system for the turbo engine and the PDK transmission, fuel efficiency technologies have reduced NEDC fuel consumption by up to 16 per cent to 29.1mpg; these figures apply to both models.
