At the moment the only EV that makes any commercial sense is a mild hybrid.
48v combination electric motor/generator serves as an engine brake regenerative device to charge battery from otherwise wasted braking energy, operates as a starter and stop/start device, gives an "overboost" for overtaking and off the line acceleration and replaces the alternator and the clutch/torque converter.
These systems are currently available to car makers as fully engineered transmissions that plug into the existing space in most current vehicles with no structural redesign required.
In addition, for very high performance applications these systems can be readily expanded with the addition of electric motors to drive the undriven axle on demand, replacing awd systems currently available with highly sophisticated and programable torque vectoring drive to individual wheels. Best applied to the front axle to add these features to a rwd chassis but the reverse is also eminently practical.
The cost of adding these features currently only makes sense in the context of the CAGW mania which artificially drives up the cost of purely conventional ICE vehicles.
The one really handy aspect of these systems from my perspective is that for fairly minimal weight penalty one gets EV only operation for about 30 miles or 50 km which is ideal for rush hour low speed driving. No noise, no stop/start effects, excellent creeping function and snappy acceleration from low speed or stationary, all with a fairly low cost increment. The ICE remains ready to kick in whenever the driver requires it to.
