Porsche has released details of its new GT3 Cup car and boy, is it a beaut. It's not just Porsche's best selling race car, it is also the most-produced GT racing car in existence. For 2017, Porsche is adding a 4-litre, six-cylinder flat engine to the mix that will produce 485-hp.
You'll also notice there's quite a few aerodynamic improvements with a new front apron and a all-new rear end. Porsche also further strengthened the engine to reduce maintenance costs and also added a valve drive with rigidly mounted rocker arms and a central oil feed, integrated oil centrifuge, and a much more rigid crankshaft.
