With better aerodynamics to cut the drag to 1/4, 3 kWh could possibly yield 200 miles range at 70 mph in a similar vehicle. It weighs 91 lbs, and with all of 13 peak horsepower, is faster to accelerate than most new 4-cylinder cars. My proof of concept single-seater I built does 150-200 miles range at 30-35 mph on only 1.5 kWh. We don’t need oversized, heavy, wasteful battery packs. Why? It’s all about two things: 1) Hoonage 2) CHEAP transportation A car that follows a similar set of design principles is also the ticket to inexpensive EVs appropriate for sports car enthusiasts. If I had the money, I’d build and sell custom-designed microcars with velomobile aerodynamics and more than 1 horsepower per lb of vehicle with AWD. It’s quite amazing what modern technology allows in the light electric vehicle space. The ones from AMZ Technologies weigh 7 lbs and make 50 horsepower peak. There are prototype motors going back 15 years ago that could allow an even more outrageous build, but they aren’t available for purchase. You’d be looking at the possibility of 0-60 mph in under 4 seconds with a vehicle that could climb anything. Lots of custom fabrication and sweat equity would be necessary, but the results would be more than worth it. Cheap $300 Chinese Leafbike motors and a PowerVelocity controller running each with a 180V battery pack of Molicel P42A batteries all controlled by a CycleAnalyst v3 computer could do the trick. With less than $5,000 worth of off the shelf but relatively low-volume parts and some scrap metal, one could build a sub-200 lb rig making 60 horsepower peak at the wheels, with AWD.
