The 911 Turbo shares its wheelbase with the Porsche Carrera, although it will be four inches longer and sit on a bit of a wider expanse between the tires. Porsche will continue its use of the 3.8-liter horizontally opposed six cylinder engine, but the new 911 will run with a tri-turbo setup, boosting the cars power from 495 to 525 horsepower. The tri-turbo setup will incorporate three seperate turbos, each designed to operate better at different RPMs. This allows the acceleration of the car to be turbo charged as well as the top end, eliminating the rubber band effect found on many turbocharged engines.
