Michael Mauer, chief designer for Porsche took time to talk to Warren Brown, Washington Post, and myself at the 2011 North American International Auto show (NAIAS) in Detroit, MI.

Mauer talked about the future of Porsche’s sports cars, and why Porsche is building a 918 Spyder Hybrid.

What does the Porsche 918 RSR mean to Porsche’s brand?

We know it’s a concept right now, but what parts will be going into production?
