Porsche 911 Turbo: 412kW auto-only coupe revealed

The 991-generation Porsche 911 Turbo and Turbo S have been revealed.

Nestling a 3.8-litre twin-turbocharged flat six-cylinder engine behind its wider rear hips �?" a further 28mm wider than the already-widened body of the Carrera 4 models �?"� the Turbo produces 383kW, up from 368kW with the previous model, and the Turbo S a fuller 412kW, up from 390kW. Torque outputs are not yet revealed.

This generation of Porsche 911 Turbo models employ only a seven-speed dual-clutch automatic gearbox, a move that follows the track-focused naturally aspirated 911 GT3 revealed earlier this year.

Together with a new Porsche Traction Management (PTM) all-wheel-drive system, active rear axle steering, adaptive aerodynamics, the Turbo gets to 100km/h in 3.2 seconds when optioned with the Sport Chrono Package Plus. That pack is standard on the Turbo S, which slices a further tenth of the time.

The top speed of the 911 Turbo S is 318km/h, and the car wearing standard production tyres is claimed to have lapped the Nurburgring in �??well under�?� seven minutes and 30 seconds.

Fuel consumption reductions of up to 16 per cent have been achieved, with both the 911 Turbo and Turbo S claimed to consume 9.7L/100km combined. An auto stop-start function is standard on both models, which now shuts off the engine during coasting to a stop, in addition to decoupling the transmission when cruising off the throttle.

Porsche claims its new all-wheel-drive system delivers �??faster and more precise power distribution to the two axles�?�. It has electronically controlled and activated multi-plate coupling and, for the first time, a new water cooling function aimed to direct more power to the front wheels than before, where necessary.

Porsche also claims that it continues to be the only manufacturer to offer two turbochargers in a petrol engine, both of which have variable turbine geometry.

The chassis of both Turbo models is 100mm longer than regular Porsche 911 models, with 20-inch wheels standard and an active anti-roll bar system optional on Turbo and standard on Turbo S as part of the Sport Chrono Package, which also includes dynamic engine mounts and ceramic brakes.

Both models introduce the rear steering first shown on the 911 GT3. Angle of the rear wheels can be varied up to 2.8 degrees depending on vehicle speed. At up to 50km/h, the rear wheels move in the opposite direction the front wheels are turned to �??virtually�?? shorten the wheelbase by 250mm and increase agility, according to Porsche.

Conversely, above 80km/h, the rear wheels turn in parallel with the fronts to �??virtually�?? lengthen the wheelbase by 500mm allowing �??tremendous stability�?�.

Active aerodynamic features standard on both 911 Turbo and Turbo S include a three-stage retractable front spoiler, an adjustable rear wing with three set positions. At the rear wing�??s maximum height, downforce on the rear wheels is claimed to improve to such an extent that the feature alone helped shave two seconds of the Turbo S model�??s Nurburgring circuit time.

While obviously based on the regular Porsche 911 models, the Turbo and Turbo S get mildly enhanced interiors, with standard Bose audio and an optional Burmester system. Radar-controlled cruise control, camera-based road sign and speed limit recognition are being offered for the first time.

The Porsche 911 Turbo and Turbo S models are due in Australia late in 2013, priced from around $360-430K.
