These are some of the more interesting new cars and concepts unveiled at Germany's International Auto Show.
Porsche finally unveiled the production version of the long-awaited 918 Spyder at the Frankfurt Motor Show. Most of the specifications are fairly well known by now. It's powered by a 4.6-liter V8 and two electric motors, one at each end of the car. It can go from zero to 62 miles per hour in 3.3 seconds and all the way to 200 in just 10.3 seconds, Porsche says.
Shortly before the unveiling, the 918 set a lap record for a production car on Germany's Nurburgring race track.
