As Porsche prepares to unveil a newly facelifted version of its 911, our spies have caught the next evolution of the hardcore GT3 RS model testing at the Nurburgring. The new GT3 RS is expected to go on sale next year, while the updated version of the standard 911 will be released within the next few months. Styling around the front and rear bumper has been subtly modified, and this lightweight, track-focused Porsche is now expected to offer around 450bhp; that’s 40bhp more than the current car. The updated standard 911 - which Autocar.co.uk will have first official pictures of this Friday (6 June) - is expected to use new direct-injection engines. However, it’s not yet clear whether the GT3 RS will follow suit because its engine block has traditionally been based on the unit from the Porsche GT1 racing car.We do know that the GT3 will get Porsche’s new seven-speed, dual-clutch transmission, officially known as Porsche Doppel Kupplung (PDK). It’s a paddle-shift-only unit and promises seamless, rapid cog-swapping. Other new touches include LED brake lights and Audi R8-style LED driving lights, set within a redesigned front bumper.
