2010 Porsche 911 GT3 Cup Race Car
Don't think there's any relevance or relationship between modern road cars and modern race cars? The Porsche 911 GT3 Cup race car shares 80 percent of its parts with the road-going version, and many of the differences are about safety and even more extreme light weight, rather than raw performance.
This video shows the behind-the-scenes look at the car, and the drivers that extract the maximum from them, in the Carrera Cup GB one-make series in the U.K., which uses exclusively Porsche 911 GT3 Cup cars. Though the video is a bit short on great track time, there's enough info and 'tainment to justify the three minutes of your day.
