I think the phrasing was imprecise and they were referring to the transmission and differential. Most EVs use a single-speed gear reduction system - one gear mesh from motor shaft to a compound gear, another mesh from that gear to the ring gear of the differential. In contrast with ICE drivetrains, there is no clutch or torque converter (the electric motor can operate from a standstill), no reverse gearing (the electric motor can operate both CW and CCW), and no synchronizers and dog-clutches (as in manual transmissions), no hydraulic logic and clutches of automatic transmissions, nor the hydraulically operated sheaves found in CVTs. We've been hobbing gears to operate at those power levels for roughly a century.

I think Porsche has done a 2-speed EV transmission and Lucid moved the differential inside the motor and has two-reduction gear sets on either side, but those are both unusual designs.
