Reimagining the electric vehicle with flat platforms: Page 2 of 3

The future looks bright for electric vehicles (EVs) despite the fact that each platform can cost manufacturers billions to design, test, and build. What’s more, carmakers often struggle to recoup these costs through pricing alone, as EVs are still built in low numbers compared to ICE vehicles. Thus, cost amortization is higher per unit.

The system uses four motors, steer-by-wire, a quad gear box, and an integrated suspension that automatically senses and levels the height at each wheel. Having individual motors in each wheel also creates the possibility of employing advanced torque vectoring, a method of power transfer that would improve both safety and handling.

The adaptation of REE’s universal framework will replace multiple platforms for OEMs, likely resulting in substantial savings. By enabling carmakers to utilize one platform for all of their electric vehicles, REE claims costs will be slashed while performance, safety, comfort, and energy efficiency will all improve.

The platform, REE says, offers automotive manufacturers multiple body configurations. It would provide the basis for vehicles ranging from high-performance cars to off-road SUVs with active suspension technology and even heavy-duty trucks.

The modular design, the company adds, provides a low center of gravity, thereby maximizing energy efficiency, increasing agility and stability, and improving performance. Once again, these are critical factors in the future success of the electric- and autonomous-vehicle revolution.

By integrating components formerly found under the hood of the car into the wheels, REE’s solution also reduces vehicle size and weight. “The concepts of the past are limited and restrict the ability of the automotive industry to realize the electric and autonomous reality they are striving for,” says Daniel Barel, CEO and co-founder (with Avishay Sardes) of REE. “Until now, the industry has operated by making incremental improvements on the traditional design of the automotive vehicle. At REE, we believe that in order to hasten the automotive revolution, we need to reinvent the wheel—quite literally.”
