It seems the Aptera will be the most efficient EV made in the world. There are a few othrs that might compare and be in the same class as the Aptera. One example could be the Twike.com . It is also a 3 wheeler and has pedals that can assist or make it move. I think the Aptera Solar back windown and roof will be much more efficient. I'm not aware of any other 3 wheelers. Some small cars like my Chevy Spark EV is pretty efficient . Many get about 4 or 5 miles per kWh. I get 7 to 9 . It's rated at 82 miles. I get 115 miles on a charge even after 30K miles. It seats 4 and is a 4 door so it's easy to get people and stuff in and out. It has a large hatchback too. I think the only thing as efficient as the Aptera would be an electric bicycle. But's it's not in the same class. 1 person, not winter or rain proof design. Very poor aero dynamics at high speed.
