Porsche has launched the updated 911 GT3 (991.2) at the 2017 Geneva Auto Show.

The biggest changes for the car come with the mechanics. The GT3 gets a redeveloped version of the 4.0-liter naturally-aspirated flat-six of the 911 R and the 991.1 GT3 RS. The engine produces 500 HP and 470 Nm of torque- while revving all the way to 9000 RPM.

The sportscar can be had with a PDK transmission or a 6-speed manual (unlike its predecessor, which did not come with the stick-shift). The 1430 kg PDK-equipped model can reach 0-96 km/h (0-60 mph) in 3.2 seconds before topping out at 317 km/h. Meanwhile, 1413 kg manual-equipped GT3 takes 3.8 seconds to reach the same speed and has a top-speed of 318 km/h.

Moving on, there’s an updated suspension, optional rear-wheel steering, carbon-ceramic brakes and a host of aero elements such as the carbon-fiber rear wing, the front spoiler and the rear diffuser.

Inside, you have a redesigned steering wheel, three different types of seats and an infotainment system with Porsche Communication Management System (which includes navigation with real time traffic and other features like Apple CarPlay) and Porsche Track Precision App as standard.

The deliveries of the new GT3 start from fall of this year (around September) and the US MSRP is $143,600.
