The General Dynamics Reconnaissance Surveillance and Targeting Vehicle is one cool piece of kit. It’s powered by four electric in-wheel motors and can export thirty kilowatts directly to the grid. It’s also got neat-o gauges.

It uses a small diesel-engine powering a generator to charge on-board batteries or power the in-wheel electric motors. Instead of mounting the wheels to studs on the motor as is normally done on hub-motor concepts, this concept works a bit differently. First the wheel is assembled on a bearing riding on an stub axle, then on goes the 90 kW peak, 50 kW continuous pancake motor mount installed on the splined hub shaft, then on top of that a pancake gear reduction unit which interfaces with an eccentrically mounted geared track one the rim of the wheel. Very, very clever. Each wheel gets an independent motor controller so even if three motors get shot out, forward motion is still possible.  Aside from being able to operate in all-silent mode, it can also export over 20 kW of power to the grid.
