The main limitation for battery powered vehicles is the mass of the battery that grows directly with race duration, and the break-even point is currently around 10 minutes. However, battery powered vehicles have other advantages such as indifference to altitude, superior traction control, and moldability of the drivetrain for aerodynamic advantage or for optimal weight distribution, making them highly competitive in certain disciplines such as land speed racing and hill climb. Keywords: BEV, demonstration, off-road, promotion, vehicle performance 1 Introduction Electric vehicles are going to be a game changer in motorsport due to their high power, instant torque, indifference to altitude, superior traction control, and moldability of the drivetrain for aerodynamic advantage or for optimal weight distribution. The main limitation for battery powered vehicles is the mass of the battery that grows directly with race duration. At the current technology level, battery powered racing vehicles can be top contenders in most races that don’t exceed about 10 minutes. The 2015 victory by Rhys Millen in the Drive eO electric car in the legendary and incredibly challenging Pike’s Peak International Hill Climb clearly demonstrates the potential.
