Porsche is planning to use a tri-turbocharged engine for the next generation 911 Turbo. The Porsche 911 991 Turbo will be powered by a 3.8-liter horizontally opposed six-cylinder engine, this much remains the same, with three turbochargers instead of the current generation’s two. The triple-turbo 911 engine would use one small turbo that spools quickly to provide low end power and reduce turbo lag.
The 2012 Porsche 911 997 Turbo shown here gets by with just two turbochargers
The 991 generation of the Porsche 911, which will debut in 2013, will get a 30-hp boost over the 997 Turbo’s 495-hp. That means the all-wheel drive Porsche 911 991 Turbo will be a 525-hp beast. Oh, and the tri-turbo system will reduce emissions and improve fuel economy, too, according to Top Speed.
Porsche probably has another reason for introducing the tri-turbo engine. With turbochargers becoming commonplace, the Chevy Cruze comes with one nowadays, Porsche’s turbo nameplate isn’t quite as special as it was in 1975. The Nissan GT-R, which is capable of hanging with the 911 turbo around a track for a fraction of the price, has proven that you aren’t paying for just performance when you buy a high-end sports car. Part of what you’re paying for is exclusivity. Porsche needs something to separate the 911 Turbo from the bourgeois turbocharged cars now flooding the market. A tri-turbo setup would certainly do that.
