Porsche's latest "precision tool for the race track" is detailed in the latest clip filmed on the company's test track in Weissach.
Power comes from a flat-six 3.8-liter engine producing 460 HP (338 kW), representing a 10 HP (7 kW) increase compared to the outgoing model. This engine is linked to a 6-speed "dog type" transmission controlled via shift paddles mounted on the steering wheel.
It has a driver-focused cockpit with a digital instrument cluster, an angled center stack and a flat-bottomed steering wheel. Inside it also gets a new racing seat, a roof "rescue hatch" and an improved roll cage.
Set to participate in next year's Porsche Mobil 1 Supercup, the 2013 911 GT3 Cup will cost from 181,200 EUR (without VAT).
Sometime next year it will spawn a road-legal variant.
