The 3,020-pound GT2 RS gets 620 twin-turbocharged horses from its 3.6-liter engine, making it the most powerful Porsche you can legally put on the roads. That's 90 more horses pushing 154 pounds less weight than in the previous version, and it gets five percent better fuel economy. Ground control is handled with tires specifically created for the car, carrying it from zero to sixty miles per hour in 3.4 seconds.
The Porsche 911 GT2 RS ($245,000) is making its world debut at the Moscow Auto Show on August 25th.
