Buoyed by the sell-out success of its Cayman GT4 and 911 R, Porsche is reportedly planning a major motorsport-inspired expansion program covering the next 12 months.

It will start in March at the Geneva motor show when the 911 GT3 will be reintroduced with a manual transmission previewed by the limited-edition R, however UK publication Autocar has cited a source further stating the 350kW 3.8-litre GT3 will move to an upgraded version of the larger 368kW 4.0-litre GT3 RS engine.

According to Autocar’s source the 911 GT2 “should be ready by the end of the year” and will see out the current 3.8-litre twin-turbocharged flat six-cylinder engine with 485kW – well up on the current 427kW Turbo S.

The big, boosted six is also set to bow out with the 991 range, with the next-generation model expected to be based on a larger version of the Carrera’s 3.0-litre turbo unit.

Although far from confirmed, the reports certainly whet our appetite. We can’t imagine Porsche engineers sitting idle while the market is left hungry for every GT car they make.
