Porsche turns up boost on 911 range with new Turbo and Turbo S

You didn't honestly think Porsche would stop with just a turbocharged Carrera and Carrera S, did you? No, that'd be silly. Of course Stuttgart had to follow up those two smash hits with a new Turbo and Turbo S. Naturally, both cars build on the 370-horsepower Carrera and 420-horsepower C2S.

The base Turbo offers 540 horsepower and starts at $160,195, while the Turbo S packs 580 horsepower and demands an extra $28,900. Adding a folding fabric top to either model will drive the cost of entry up by $12,300, regardless of output. For those keeping track at home, that's a 20-horsepower bump for both vehicles over the previous models, while the Turbo's price jumps by $8,100 and the Turbo S will cost an extra $5,400.

In terms of actual performance, the Turbo hits 60 in just 2.9 seconds and will carry on to 198 miles per hour, a one-tenth and three-mph improvement over the current car. Going for the Turbo S will only shave a tenth of second off the 60-mph sprint, although you'll pick up an extra seven mph on the top end. That compares favorably to the current car, which takes 2.9 seconds to get to the magic six-oh and stops accelerating at just 197.

The stopwatch improvements are only part of the story. Porsche claims the new dynamic boost function will maintain turbo pressure during sudden throttle load changes, like you might experience when pushing the 3.8-liter, twin-turbocharged flat-six hard. That means snappier throttle response. As with the current 911 Turbo and Turbo S, Porsche's excellent dual-clutch transmission is the only way to fly.

Both cars also get Porsche's Sport Chrono Package and Porsche Active Suspension Management as standard, while upgrading to the Turbo S will add Porsche Dynamic Chassis Control and carbon-ceramic brakes. While there's lots of free hardware, we're betting Porsche's options catalog will remain just as robust.

As for the design, you can expect the same look shown on the new, turbocharged 911 Carrera, albeit with some Turbo and Turbo S exclusives. 20-inch wheels are standard, with super-wide rubber in the back – Porsche doesn't list tire specs, but the rear hoops are 11.5-inches wide.

Both the 911 Turbo and Turbo S will get their big debut at the 2016 Detroit Auto Show. Naturally, we'll have much more then, including live photos from the show. In the meantime, read on for the official press release from Porsche.
