Yahoo Autos Porsche unveils the 963 racer at Goodwood
The LMDh class created by IMSA in the U.S. and France's ACO starts racing next year, competing in the both the IMSA WeatherTech SportsCar Championship and the FIA World Endurance Championship. The cars will create a new GTP class populated by Acura, Alpine, BMW, Cadillac, Lamborghini and Porsche. We've seen the BMW and the Cadillac. Porsche used the Goodwood Festival of Speed to unveil its new 963 racer that will run with the Penske Motorsport team. The German and American racing outfits last partnered from 2005 to 2008 in the LMP2 class with the RS Spyder in its unmissable yellow DHL livery. This time the duo aim to take overall victories at races like Daytona and Le Mans, the 963 dressed in Porsche Motorsport's traditional red, white, and black.
Porsche chose its spec chassis from Canadian firm Multimatic, the spec hybrid unit in back attached to Porsche's in-house 4.6-liter twin-turbo V8. The automaker says the engine traces its roots to the 918 Spyder hybrid hypercar, the 918 engine built on the same architecture as the 3.4-liter V8 in the aforementioned RS Spyder. The 918 also fitted a 4.6-liter V8, but it was naturally aspirated, unlike the mill in the new 963. The TTV8 produces 670 horsepower, a touch under the maximum allowed.
