As promised, the latest 911 Turbo has made its world premiere at the North American International Auto Show in Detroit.
The second generation 991 Turbo features 20hp more power, sharpened design and improved features over its predecessor.
The bi-turbo six-cylinder engine in the 911 Turbo with 3.8 litres of displacement now has a power output of 540 hp. This power gain was achieved by modified inlet ports in the cylinder head, new injection nozzles and higher fuel pressure. The 911 Turbo S now develops 580 hp thanks to new turbochargers with larger compressors.
