Motor racing will undergo several changes in 2015.
Major driver changes also will be part of Formula One, with four-time champion Sebastian Vettel moving to Ferrari from Red Bull Racing. Two-time champion Fernando Alonso, whose departure from Ferrari made room for Vettel, returned to the McLaren-Honda team he raced with in 2007.

DeJoria three times raced down the 1,000-foot drag strip in less than four seconds, the only female funny car racer in history to do so. Her latest sub-four-second pass came at the final event in Pomona in November, when she ran 3.998 seconds at 311.41 mph.
What's new in motor racing for 2015?
The arrival of Formula E, a series featuring electric-powered race cars competing on city courses around the world. The series makes its U.S. debut April 4 on the same street course in Long Beach that will be used two weeks later for IndyCar's Toyota Grand Prix.
