Following the spy shots revealed yesterday of the upcoming Porsche 911 Turbo playing in the snow is a fantastic bit of news about what it will be carrying under that luscious hood. Turns out, the 911 Turbo will be powered by a 3.8 liter, horizontally opposed six-cylinder engine, but not equipped with a twin-turbo system as one would expect. Instead, Porsche is following in BMW’s footsteps by offering a tri-turbo system.
This system is currently in the final phase of development and, according to the first details, will help raise the engine’s output from the current 495 HP to somewhere in the region of 525 HP — or the same as that of the current 911 Turbo S . It will include the usual twin turbochargers found in the current engine, but will get a smaller unit mounted close to the engine to boost low-end response. This system will also improve fuel economy and reduce CO2 emissions.
