We'll take any excuse to spend some more time looking at the Porsche 918 RSR, but fortunately, this excuse is also informative. Anthony Hatter, Porsche's design manager for sports cars, walks us through some of the key elements of the 918 RSR.

It's not all academic, either: Porsche is planning a production 918 Spyder with much of the same aesthetics and technical abilities. For more on that car, check out our previous coverage here.
