Looking to explore how far it can push the limits of electric vehicle performance, Ford has created a version of its Mustang Mach-E SUV with seven electric motors that can produce a total of up to 1,400 horsepower.

The Mach-E 1400 is a one-of-a-kind demonstration car that was created to show the potential of all-electric vehicles and to help engineers research ways to increase their power, said Mark Rushbrook, head of Ford Performance Motorsports. The Mach-E 1400 is based on Mustang’s Mach-E SUV, which Ford will begin selling next year. The street legal Mach-E GT SUV will produce 459 horsepower from two electric motors.
