33 Porsche 911s will race in the 24 Hours of Nürburging, including the new GT3 R Hybrid. Full details inside.

Porsche has announced 33 911s will compete in this weekend's 24 Hours of Nürburging.

Key entries include two 911 GT3 R's from Manthey Racing, a 911 GT3 R from Mamerow Racing, and a 911 GT3 RS being driven by former DTM racer Roland Asch, TV commentator Patrick Simon, and journalist Chris Harris (among others).

More importantly, Porsche's 911 GT3 R Hybrid will have its racing debut. It features two 60 kW (80 hp / 82 PS) electric motors, a 353 kW (473 hp / 480 PS) 4.0-liter flat-six engine, and an electrical flywheel power generator. The latter enables the electric motors to be instantly activated for an additional 120 kW (161 hp / 163 PS) for 6 to 8 seconds.

According to Hartmut Kristen, Head of Porsche Motorsport, "This year, Porsche is particularly well represented at the Nürburgring 24 hour race by its vehicles, customers and drivers. We regard this diversity as a clear commitment to the 24 hour event. Our customer teams compete with strong driver contingents, with some receiving support from our Porsche factory drivers. I'm especially curious about our 911 GT3 R Hybrid. We're not setting our sights purely on race results, but more on the data that our race lab delivers for the further development of hybrid technology."
