If you thought that since the entire Porsche 911 lineup (save for the GT3 and GT3 RS) is now turbocharged whether the top-end 911 Turbo would somehow be left behind, then you're very wrong. Set for a live debut at Detroit next month, Porsche has just pulled the sheets off its facelifted 911 Turbo and 911 Turbo S. As before, both a coupe and convertible will be offered. But in order to keep the Turbo the top dogs, a power increase was required. The 3.8-liter bi-turbo flat-six now produces a total of 540 hp while the Turbo S offers up 580 ponies.

That's a 20 hp increase for both versions over their immediate predecessors. How was this done? Well, Porsche employs a bunch of German mad scientists/engineers, for starters, who modified the inlet ports in the cylinder head, new injection nozzles and higher fuel pressure. Porsche also adds the engines feature a dynamic boost function to further improve engine response in dynamic operation. Translation: it maintains the charge pressure when the accelerator pedal is released briefly. Performance is as impressive as always. The Turbo S coupe makes the sprint from 0-62 mph in 2.9 seconds with a new top speed of 205 mph. The Turbo makes that same 0-62 sprint in 3 seconds flat and a top speed of 199 mph.

Porsche managed the improved numbers by tweaking the electronic engine and transmission management system. Fuel consumption has also been reduced as a result. The exterior received some minor updates, notably new door handles, updated taillights, and new 20-inch alloy wheels. There's also a new engine cover and slightly restyled rear bumper. The Sport Chrono Package is standard fare, which now includes a new Sport Response button that "preconditions the engine and gearbox for the best possible responsiveness at the push of a button." There's also a new PSM Sport Mode button that can alter the intervention threshold of the Porsche Stability Management system.

This allows for drivers to approach the vehicle's performance limits even more closely. The interior remains largely unchanged, save for a new sport steering wheel with a rotary ring to select one of four driving modes: Normal, Sport, Sport Plus, or Individual. There's also an updated infotainment system and a standard Bose audio system. The 2016 Porsche 911 Turbo range will go on sale in Germany in late January with a starting price of 174,669 euros.
