Porsche reveals 911 Turbo upgrades

Porsche is set to show its facelifted 911 Turbo range at the North American International Auto Show (NAIAS) in Detroit, Michigan, USA in January with engine tweaks bringing an extra 20ps.

The range-topping Turbo and Turbo S models have been boosted to 540ps and 580ps respectively, which takes the coupe models to 100km/h from standstill in 3.0 and 2.9 seconds.

The 3.8-liter twin-turbo six-cylinder engine has received modified intake ports in the cylinder heads, new fuel injectors and higher fuel pressure to achieve the power boost. The Turbo S variant gets a new turbocharger with a larger compressor. Porsche says that it is the only manufacturer to use turbochargers with variable turbine geometry in gasoline engines.

Another new feature for the cars is a dynamic boost function, which improves throttle response when required. It maintains boost pressure during load changes by interrupting fuel injection while the throttle valve remains partially open. Porsche says that it makes the engine responsive to changing throttle applications with minimal delay.

Despite the increase in performance, which includes a top speed of 319km/h (198mph), the Turbo model has managed an improvement in fuel economy of 0.6 liters less fuel per 100km of driving due to adjusted engine and transmission management software.

The NAIAS is to be held on January 11-24, 2016, at the Cobo Center in Detroit, Michigan.
