New spy pictures of an undisguised 2017 Porsche 911 GT3 at the Nürburgring show that the car will get redesigned tail lights and a new rear bumper.

The 2017 car will also get a revised front end, with more aggressive air intakes in the front bumper, a redesigned front spoiler, air intakes and new LED indicators, along with a new diffuser at the rear.

The rest of the car’s styling looks to be largely carried over from the current model, including the slit grilles at the front and back, large rear wing and central twin exhausts.

The images come just weeks after computer generated images of a 911 GT3 were leaked onto a Dutch blog (shown in the gallery). The test car looks to have the same exterior as the CGI car, suggesting the leaked images were accurate.

Other changes to the facelifted 911 GT3 will include a manual gearbox option for the first time since production of the 997 911 GT3 ended in 2011. GT3 guru Andreas Preuninger confirmed the option of a six-speed manual gearbox at the launch of the 911 R earlier this year. The GT3's 'box will be identical to that car's.

Despite the rest of the 911 range now being turbocharged for added efficiency and reduced emissions, the facelifted car will maintain the naturally aspirated 3.8-litre engine of the current generation GT3.

The current 911 GT3 pumps out 468bhp and 324lb ft which, combined with its 1430kg kerb weight, equates to a 0-62mph sprint of just 3.5sec and a top speed of 196mph.
