Yes - Hybrid:
Porsche's first racecar to feature electric power sourced from a duo of motors that send power to a generator attached the flywheel. Like many hybrid production cars, the motors are charged whenever the brakes are applied, and the driver can use the extra power for 6-8 seconds for overtaking.

Porsche plans to do extensive testing with the 911 GT3 R Hybrid after jetting from Geneva, including a trial-by-fire at the Nurburgring 24 Hour race from May 15-16. Porsche claims that it has no intention of winning the race, but we can't imagine that they won't be at least competitive.
