Porsche will be off to a powerful start in 2016 when the 2017 911 Turbo and 911 Turbo S make their world debut at the North American International Auto Show in Detroit in January. The top-of-the-line 911 models will be available in both coupe and convertible body styles and are equipped with engines offering 20 horsepower more than before, a sharper design, and enhanced features. The 3.8 liter twin-turbo six-cylinder engine powering the 911 Turbo now develops 540 hp. The increase in horsepower is achieved through modified intake ports in the cylinder heads, new fuel injectors, and higher fuel pressure. The 911 Turbo S now makes 580 hp thanks to new turbochargers with larger impeller. In addition to a higher maximum torque (553 lb.-ft. in overboost compared to 523 lb.-ft. on the Turbo), the Turbo S also has a higher redline (7200 rpm instead of 7000). Porsche is still the only manufacturer to use turbochargers with variable turbine geometry in gasoline engines.

The engines now also have a dynamic boost function, which improves throttle response during spirited driving. It maintains the boost pressure during load changes – i.e. when the accelerator pedal is briefly released. This is achieved by interrupting fuel injection, while the throttle valve remains partially open. As a result, the engine responds to changing throttle applications with practically no delay. The effects of this function are particularly pronounced in the Sport and Sport Plus modes. The powertrain enhancements take the performance of the 911 Turbo models to even higher levels than before. The 911 Turbo S Coupe accelerates from 0 to 60 miles per hour in 2.8 seconds, making it 0.1 seconds faster than its predecessor. Its top track speed of 205 miles per hour has increased by 7 miles per hour. The 911 Turbo reaches 60 miles per hour from standstill in 2.9 seconds, and its top track speed is 198 miles per hour – 2 miles per hour faster.

The Sport Chrono Package is now a standard feature on all 911 Turbo models. This includes the new GT sport steering wheel in 918 Spyder design measuring 360 mm or 14.1 inches in diameter and is equipped with a mode switch. It consists of a rotary ring with stepped positions that can be used to select one of the four drivetrain modes Normal, Sport, Sport Plus, or Individual. The Individual setting lets the driver configure and store her or his preferred vehicle setup, including PDK shift strategy, throttle response and damper control. Another new feature of the Sport Chrono Package is the Sport Response button. When the black button located in the center of the mode switch is pressed, it preconditions the engine and transmission for the best possible responsiveness. In this state, the vehicle can produce optimal acceleration for up to 20 seconds.
