The current BMW i8 uses a plug-in hybrid powertrain to produce a total output of 357 horsepower. But the future version of the i8 could switch to a full EV powertrain.
Sources tell Autocar that German automaker would swap the turbocharged three-cylinder in the rear for two electric motors. Each electric motor (there would be three including one up front) is said to produce up to 268 horsepower.
With the addition of two electric motors, BMW will add a larger battery. To allow for this, the i8's carbon fiber structure would be modified. BMW already has some ideas as to how to do this as they did an i8 hydrogen prototype where they had to modify the structure to allow hydrogen tanks. Despite the larger battery, sources say going the electric route would allow the vehicle to keep the same weight as the current model - 3,274 pounds.
