The two engine options are eco friendly- you can choose from an all-electric or plug-in hybrid version. The all-electric is powered exclusively with batteries, to last approximately 120 miles. At night you simply plug the Aptera into any standard 110 volt outlet and in just a few hours you will have a fully charged vehicle.
The plug-in series hybrid is powered by an electric drive train, assisted by a fuel efficient gasoline powered generator, stretching the travel range significantly further. In typical driving you may achieve over 300 miles per gallon and you will have range far beyond any passenger vehicle available today.The design of the Aptera includes all the standard features, including airbags, a rear view camera, GPS navigation, and a CD/MP3/DVD player. It also includes a RFID key fob to start the car, and a solar assisted climate control system. The approximate cost of the Aphera will be
$26,900, and you can reserve your own wingless auto for a fully refundable $500.
