2016 Porsche 911 Turbo and Turbo S revealed

The facelifted Porsche 911 Turbo S will be fastest-accelerating Porsche 911 production model when it is launched in the UK at the end of this month, with a 0-62mph time of just 2.9sec – some 0.2sec faster than its predecessor.

The new 911 Turbo S is also among a select group of road going 911 models to boast a top speed in excess of 200mph, with official performance claims pointing to a potential maximum of 205mph – the same top speed achieved by the frenzied 611bhp 911 GT2 RS produced in 2010.

The new 2016 model year 911 Turbo S, which will be sold in both coupé and cabriolet body styles, retains the same twin-turbocharged 3.8-litre horizontally opposed six-cylinder direct injection petrol engine as its predecessor, which first went on sale in the UK in 2013.

However, detailed changes to the inlet ports within the cylinder head, among other minor modifications to the variable vane turbocharger, have liberated an extra 20bhp, providing the new 911 Turbo S with a stout 572bhp – or more than 150bhp per litre.

No official torque figures for the new car have been revealed, although Porsche sources suggest it retains the same 553lb ft as the old 911 Turbo S owing to loading limitations with its standard seven-speed dual clutch gearbox and four-wheel-drive system.

At the same time, the standard 911 Turbo has also been updated for 2016. Also available in coupe and cabriolet forms, it receives a less aggressively tuned version of the same engine, kicking out 18bhp more than its predecessor at 532bhp.

Yet despite giving away some 40bhp to its more highly tuned sibling, it is claimed to hit 62mph from standstill in 3.0sec and run to a top speed of 199mph in coupe form, for respective improvements of 0.4sec and 3mph.

To reduce the effect of turbocharger lag and provide what Porsche describes as sharper throttle response, both the new 911 Turbo and 911 Turbo feature a so-called dynamic boost function. It maintains the boost pressure, with the throttle valve remaining open and power interrupted by cutting the fuel injection on a trailing throttle.
