There's been a lot of recent speculation about what exactly Porsche will unveil at the Detroit Auto Show in just a week's time. Well, add one more rumor to the list.
According to AutoBild, Porsche will pull back the covers on a coupe version of it's 918 Spyder concept. Designed for track, not street, duty, the 918 coupe is likely to weigh even less than the 3,300-lb curb weight of the Spyder concept and is likely to use a different engine. The original concept made use of a high-tech hybrid system that combined a 500-hp 3.4-liter V8 borrowed from the RS Spyder race cars and matched it with 218-hp of electric thrust.
This coupe model could use a more conventional turbocharged V8, although considering the success Porsche has had with its GT3 R Hybrid race car, it could be the next step in the German sports car maker's hybrid racing strategy.
