This innovative side- by-side two seat city car eschews a steering wheel for outstanding visibility and ease of entry/exit instead by using two control sticks and buttons to control the speed and direction of the car. A lightweight aluminum chassis and all-electric drive using high torque motor operating a wheel speed (no transmission or gear reduction needed) with integral differential weighed in at just 1545 pounds. This car uses an 800V lithium-ion manganese battery pack and an inverter adapted from a wind turbine power generator. This unusually high vehicle voltage level reduces electrical losses and increases overall vehicle efficiency while using standard electric components. Employing a technique just now being considered by OEMs, this team charges their batteries through their motor and controller.

  • keep it under 20K and I am in!!

  • I think it's beautifull.

  • no steering wheel no dice.

  • Great to see cars change to be more efficient. I like this concept!

    

  • Germany may be willing to subsidize this bullshit...but the Real World never will. Show me the pro forma!

  • It would be better with a steering wheel. I tried "lever" steering in the 1970`s and it sucked. Not enough control.

  • looks great

  • it will cost 80.000 us I am sure as great as it looks ..it must have a big price
