The baddest street-legal 911 variant won't be seen publically until Frankfurt in September, but
Porsche has just released photos and specs on the car it will use as the basis for homologating its international GT competitor. Lighter, more powerful and loaded with body and chassis enhancements, the 2010 911 GT3 RS does share its 3.8-liter flat-six engine with the standard GT3. However, modifications to the RS-spec version bump output from 435 to 450 horsepower and let it rev to 8,500 rpm. This super six is backed by a mandatory six-speed manual transaxle with a deeper ratio set and short-throw linkage. It's also positioned by Porsche's slick "dynamic" engine mounts that automatically change stiffness to match the aggressiveness of any particular driving condition. To help in the mass-trimming efforts, the new RS teams its lightweight racing seats and roll cage with a titanium exhaust system and will offer an optional lithium-ion battery that's 22 pounds lighter than the GT3's conventional lead-acid unit. Visually, the new RS has an even more aggressive posture than the GT3 with a lower ride height, wider track and more aggressively bulged fenders to handle massive tires -- 245/35 front and 325/35 rear -- on staggered width 19-inch forged alloy wheels. Completing the look is a mega-scaled, but quite functional, carbon-fiber rear wing. To keep it suitably stuck to the track, the RS comes from the factory with its own unique chassis setup, including a dedicated version of Porsche Active Suspension Management (PASM). Expect to see the 2010 911 GT3 RS here in early spring with a starting price of $132,800.
