*Not all vehicles may be present at the show.
The Porsche 911 Turbo has a 520-horsepower engine, the Porsche 911 Turbo S has a 560-horsepower engine. The Porsche 911 Turbo has an EPA fuel economy of 17 MPG and 24 highway. Instead of hot compressed air entering the combustion chambers, we now have cooler air generating more power and torque. As a consequence, there is a major improvement in engine efficiency. And therefore lower fuel consumption, even under heavy loads and at high revs.
