The new 911 Turbo is set to be more potent and economical thanks to an advanced tri-turbo system.
Following the release of 2013 911 Turbo spy shots, new information has come to light regarding the engine setup. According to Autocar, the German car maker has recently submitted patent applications about their new system. Allegedly, more power and better fuel efficiency is to come from the same 3.8-liter horizontally opposed six-cylinder engine as per past models, due to a new boost courtesy of a complex tri-turbo setup similar to that seen recently in the BMW M550d and X5 M50d.
The system is made up of one smaller turbocharger and a pair of larger ones. The smaller unit is mounted close to the engine for low-rev response and the two heftier ones are similar to the Bog Warner units currently in operation. Benefits of this system include increased overall power, a more linear delivery at low revs, and improved efficiency that, coupled with the new seven-speed manual transmission, is expected to result in significant fuel savings. Horsepower ratings aren't yet known, but it looks set to increase to around 525hp so will deliver about the same as today's 911 Turbo S.
The new tri-turbo system is also being earmarked for the next-generation 911 GT2 and GT2 RS successor, which use a tweaked version of the Turbo's engine.
