Aptera Motors is a startup company seeking to manufacture high-efficiency road vehicles. Formerly known as Accelerated Composites, the company was based in Oceanside, California. The company was bought by a Chinese auto manufacturer in mid-2012 and reactivated as a going concern after having announced closure on December 2, 2011.

Aptera’s first product, a three-wheeled two-seater named the Aptera 2 Series, was under development,[4] The fuel efficiency of 300 mpg-US (0.78 L/100 km) when plugged in every 120 miles (190 km) would make it one of the most fuel-efficient cars in the world. This is without accounting for the fuel used for generating the power that charges the batteries. If that is provided for, the equation would stand significantly altered.

The name Aptera is Greek for “wingless,” a nod to their light-aircraft-inspired design and construction techniques, and is correctly pluralized either as 'Apterae' or ‘Apteras.’ However, Aptera Motors maintains that Aptera translates to “wingless flight.”
