On 15 September 2011, Porsche unveiled the seventh generation Porsche 911 which would become known by its the internal designation - 991.
Almost seven years later, Porsche Motorsport has reveled what is likely to be the last model in the 991-gen family tree - the 911 GTR RS.
A replacement to the 991 (code-named 992) is rumored to break cover at the Geneva Motor Show next month. But before that model heads to production, the 991 GTR RS could bring an end to the current-generation 911, screaming it's headers off at 9,000rpm.
The purpose of the 991 GT3 RS couldn't be clearer - Porsche states the models intent in the first line of the press release: 'A clear focus on motorsport.'
Porsche's latest high-performance sports car - the third GT road-approved model launched in a calendar year - will leave the production line with the most powerful naturally-aspirated flat-six ever fitted to a 911.
The four-litre engine produces 383kW, (15kW more than its predecessor) and is bolted to a specially calibrated seven-speed PDK transmisson. Working together the 911 GT3 RS will accelerate from 0 to 100km/h in 3.2 seconds and onto a top speed of 312km/h.

The 911 will feature a wider, weight-optimised bodykit with a large rigid rear wing, with equally racy bucket seats made of carbon in the cabin.
Lightweight door panels, opening loops (in place of door handles), reduced sound absorption and a new lightweight rear lid add to the racing feel inside.
For those wanting even more (or less depending on how you look at it), Porsche Motorsport offers an optional Weissach package offering more weight saving parts.
The package includes carbon components for the chassis, interior and exterior, as well as optional magnesium wheels. In its lightest formn, this package reduces the weight of the 911 GT3 RS down to 1,430kg.
But if you're the type who likes something for nothing, Porsche has the Clubsport package waiting for you which is offered at no extra cost - including a roll-over bar, fire extinguisher, preparation for a battery disconnect switch and a six-point belts.
Also as standard, a set of 20-inch lightweight wheels with newly developed 265/35 sports tyres on the front axle and 21‑inch wheels with 325/30 tyres for the rear.
Although the official release is scheduled for Geneva next month, the new 911 GT3 RS is available to order now. It will be launched in Germany from mid-April 2018 (because they always go first) before models start heading further afield later in the year.
