While all versions of the Porsche 911 will henceforth have turbochargers, the Turbo and Turbo S models still stay at the top of the model hierarchy. And to keep those models in their rightful place, the 2017 Porsche 911 Turbo and Turbo S receive even more horsepower just in time for their public debut at the 2016 Detroit auto show in January.
In the 2017 Porsche 911 Turbo's 3.8-liter twin-turbo flat-six, output rises from 520 hp to 540 hp, thanks to redesigned intake ports, new fuel injectors, and higher fuel pressure. In the Turbo S, output also climbs 20 hp to 580 hp, and the engine's redline rises from 7,000 to 7,200 rpm. Peak torque during overboost climbs to 553 lb-ft. Both engines also have a new "dynamic boost function" to reduce turbo boost losses during upshifts. The engine computer keeps the throttle open and instead cuts fuel injection during shifts, which Porsche claims makes the engine respond to throttle inputs "with practically no delay."
With the extra oomph, the 2017 Porsche 911 Turbo and Turbo S hit the 60-mph benchmarks in even less time than before. The Turbo S coupe does the deed in 2.8 seconds, 0.1 second quicker than before, and the car's top speed rises from 198 to 205 mph. The standard 911 Turbo coupe takes 2.9 seconds to reach 60 mph and tops out at 198 mph. Despite this extra performance, Porsche says fuel economy will improve thanks to revisions to the seven-speed PDK dual-clutch automatic transmission.
New look, new features
Like the 2017 Porsche 911 Carrera and Carrera S, the Turbo and Turbo S receive a very mild visual refresh consisting of a new front bumper, restyled headlights, new 20-inch wheels, a new rear bumper, reshaped taillights, and new exhausts.
New features on the 2017 Porsche 911 Turbo and Turbo S include a Sport Mode for the Porsche Stability Management (PSM) electronics, which is said to have a higher threshold for enthusiastic driving before the stability control intervenes. A new Sport Response button, part of the Sport Chrono package, adjusts the engine configuration "for the best possible responsiveness" by putting it into an overboost mode for 20 seconds.
On all 911 Turbo models, LED headlights, parking sensors, a backup camera, and the Sport Chrono package become standard. The Turbo S adds features like 18-way power seats, a two-tone leather interior, and extra carbon fiber interior trim. Porsche's active anti-roll system and carbon-ceramic brakes are also standard on the Turbo S.
As ever, the Turbo models will remain among the most expensive in the Porsche lineup. The 2017 Porsche 911 Turbo coupe will set buyers back $160,195 and the Turbo Cabriolet is $172,495. Moving up to the Turbo S costs $189,095 for a coupe or $201,395 for the Cabriolet. All prices include a $995 destination charge.
