LA 2009: Lighter, More Powerful Porsche GT3 RS Arrives in the U.S.

Porsche’s barely street-legal GT3 RS has received a long list of mid-cycle upgrades for 2010, including a larger and more powerful engine as well as an even lighter curb weight.

Thanks to an increased displacement from 3.6 to 3.8-liters, the new engine makes an additional 15-hp for a new total of 450. That power hits the ground (as it should) through a rear-drive setup and a six-speed manual transmission. Plus, the gear ratios for the 2010 model have been shortened further for increased acceleration.

As the GT3 RS is all about performance through light-weight, additional weight has been shaved off the body of the GT3 RS through the use of a titanium exhaust. Porsche will also offer an optional lithium-ion battery in place of the standard lead battery, which will help save an additional 22 lbs.

In terms of handling, the GT3 RS gets a dynamic engine mounts, which change their stiffness depending on how the car is being driven. A new special PASM suspension setup has also been included that takes into account not only the RS’s wider rear track, but also its wider front track (new for 2010). Inside those flared fenders you’ll find 19×9-inch wheels with 245/35/19 tires up front and 19×12-inch wheels with 325/30/19 tires in the rear.

The 2010 GT3 RS will be available as of March with pricing is listed at $132,800 ($163,000 CDN).
