From their site, they intend to make all the essential parts for crash safety out of printed plastic.
Everything on the car that could be integrated into a single material piece has been printed. This includes the chassis/frame, exterior body, and some interior features. The mechanical components of the vehicle, like battery, motors, wiring, and suspension, are sourced from Renaultâ(TM)s Twizy, an electric powered city car.
Also on their site has the specs.
Motor - 5 bhp or 17 bhp, 42 lb-ft torque*
Top Speed - approx. 50mph*
The "*" indicating there should be a footnote explaining it, is missing.
Actually, their donor car (Renault Twizy) isn't even classified as a car. It's a quadcycle, and is not currently legal for road operation in the United States. From what I found elsewhere, Renault isn't even planning to make it available in the US, since it doesn't meet the road requirements here.
