" We recently tested the new 911 GT3, but at the Frankfurt Motor Show Porsche rolled out the RS version that serves as the homologation foundation for the racing GT3. Completely street-legal, the RS version is everything the GT3 is, but even more serious, and probably a tad extreme for daily street use.   For starters, the car&amp;#039;s new 3.8-liter flat-6 (up from 3.6 liters) packs an extra 15 bhp, bringing the naturally aspirated total to 450 bhp. Other RS changes include a 6-speed manual transmission (the only gearbox available) with both shorter gear ratios and shorter throws than in the GT3. A new option on the RS is a lithium-ion battery, which reduces weight by over 22 lb. The car also comes with RS-specific tuning for its active suspension, along with wider front and rear tracks and similarly widened bodywork. You can spot an RS easily by its giant carbon-fiber fixed rear wing.   Porsche calls the 911 GT3 RS &amp;quot;the most dynamic 911 to date.&amp;quot; We believe them. It goes on sale in the U.S. early this spring for $132,800. "^^<http://www.w3.org/2001/XMLSchema#string>
