991 Gets the Turbo Treatment. The 2017 Porsche 911 Turbo

Posted by: Shelton Kwan onJanuary 11th, 2016

While Porsche has downsized the 911 line’s engines to smaller and more efficient turbocharged motors, only the top of the line model will be blessed with the Turbo name. Porsche unveiled the 2017 911 Turbo and Turbo S here at the North American International Auto Show in Detroit, rounding out the 991 generation with the most powerful street models in the 911 line.

The 3.8L twin turbo boxer 6 now develops 540hp in Turbo guise, with the Turbo S putting out a whopping 580hp. Changes to attain this horsepower jump includes modified intake ports, new direct injection fuel injectors, and higher fuel pressure, while the Turbo S gets an even bigger turbocharger with larger impellers.

The new engine also includes what Porsche calls dynamic boost. Simply put, it keeps the boost up off throttle by keeping the throttle partially open and cutting fuel, allowing the turbo do continue spinning without hitting the closed throttle plate. It’s very similar to the now banned “cold blowing” setup from Formula One. Performance of the new package is impressive. The Turbo S rockets to 60mph in only 2.8 seconds, while the slightly less powerful Turbo model requires 2.9 seconds. The traction control system features a new PSM Sport mode, which compared to the existing Sport Plus mode, allows higher thresholds before intervening, resulting in a little more sideways fun before the nanny kicks in to save you from losing control.

The 2017 Porsche 911 Turbo and Turbo S will arrive in dealerships in April. The 911 Turbo starts at $159,200, with the Cabriolet version clocking in at $171,500. On the more extreme side of things, the Turbo S starts at $188,100 with the Cabriolet version breaking the $200k barrier at $200,400. No word on Canadian prices just yet.
