The holy grail of electric vehicle technology is in-wheel electric motors, which put power directly to the street and eliminate a host of other parts. In-wheel electric motor maker Portean claims that by next year, production of their revolutionary product will begin.
Weighing just 68 pounds, but capable of delivering 100 horsepower and 735 ft-lbs of torque per wheel, the Protean in-wheel electric motor would eliminate things like driveshafts, differentials, and transmissions. That reduces the cost and complexity of electric drivetrain setups, and drops a whole lot of weight as well. Mercedes tuner Brabus used two Protean motors in their beastly diesel-electric hybrid to great effect.
That’s only a few of the advantages of in-wheel motors though. Each motor can be controlled independently, allowing for more control in dicey situations. Protean also claims their electric motors can reclaim up to 85% of the kinetic energy via regenerative braking. The Protean system can also be retrofitted to existing vehicles fairly easily.
Sounds amazing, right? With production scheduled for next year though, I am left wondering…what automakers are signed up for this awesome tech? Or will Protean sell these as stand-alone units directly to customers? So many possibilities…what will come of it all?
