When we first encountered REE’s ultra-modular EV chassis, we struggled to know what to make of it. Speaking to CEO Daniel Barel, we couldn’t seem to pin down any specifics. What is it? A flat, modular vehicle chassis in which all steering, suspension, motor, gearbox and braking functions are bundled up into removable, replaceable “corner units” in the wheels.
These corner units have built-in electronics so that every single function can be fully electronically controlled. It’s not just drive-by-wire, it’s steer-by-wire, brake-by-wire, everything-by-wire. So you can put a steering wheel and pedals in if you want, but it’s just as happy to take instructions from an autonomous drive system, or heck, even a remote control. There’s no difference as far as the chassis is concerned.
