With few exceptions, Porsche has always offered a racing variant of its hallowed 911. The latest iteration of the legendary sports car seems to be no exception, as the German automaker recently introduced its new 2011 911 GT3 RSR.
Like its road car siblings, the new top-of-the-line racer is rooted in evolution, not revolution. The exterior bears a considerable resemblance to the 2010 GT3 RSR, but minor tweaks reportedly help reduce understeer. To do this, Porsche increased the front wheels' width from 11 to 12 inches, while reshaping the front lip spoiler to increase downforce. Aerodynamicists also reshaped the rear wing, reshaping the air outlets to help improve engine airflow.
Speaking of the engine, the GT3 RSR continues to use a 4.0-liter flat-six engine, but the 2011 car receives a new engine computer, along with revised intake and exhaust systems. As a result, Porsche was able to eke an extra five ponies from the mill (bringing the total to 455 horsepower), while allowing the GT3 RSR to perform better on a wider variety of fuel grades.
Apart from these minute changes, Porsche designers and engineers have left the 911 GT3 RSR formula untouched. As a result, the race-prepped car carries on with a six-speed sequential manual gearbox, a triple-plate carbon fiber clutch, an adjustable racing suspension, six-piston front brake calipers and four-piston rear calipers, an adjustable rear wing, and a brake balance bar.
If this sounds like the ideal racer to tackle GT3-class events with, give Porsche's Motorsports operations a call. The new 911 GT3 RSR is expected to reach customers later next year, carrying a price of roughly $543,000 in Europe.
