Frankly, I prefer something simpler: Toyota Yaris, for example.
Simple: no batteries, no complexity. Just a low mass car with an efficient engine and a manual transmission.
We could cut gasoline usage greatly by banning automatic transmissions, although it is politically infeasible. A good stick transmission driven by someone who knows how, will get 15% to 20% better mileage than the same car with an automatic transmission. Knowing how includes gliding to stops, keeping the car in the highest gear that does not lug, accelerating no faster than necessary, etc.
