The next gen Tesla Roadster is due to go on sale as early as 2020.
620 mile range on a reported 200kWh battery. Doing the very rough math, than is about
104MPGe.
0-60MPH in 1.9 seconds - staggeringly quick! The
quickest production car, ever. Also 250+ MPH top speed.
All wheel drive, and has four seats.
Very expensive in an absolute sense at $250k - but very cheap relative to the super / hyper cars it will replace; which cost as much as several million dollars.
