Making its debut at the show this year is La Vecchia's Quant e-Sportlimousine, whose power system is somewhere in between the two--using a technology known as flow cells. It features a powertrain developed by nanoFLOWCELL, a German company with technical ties to Bosch. Breaking it down to simple characteristics, flow cells are like batteries, but share aspects of electrochemical accumulator cells with those of fuel cells.

Pulsed Plasma Thruster A Pulsed Plasma Thruster (PPT), also known as a plasma jet engine, is a form of electric spacecraft propulsion. PPTs are generally considered the simplest form of electric spacecraft propulsion and were the first form of electric propulsion to be flown in space, having flown on two Soviet probes (Zond 2 and Zond 3) starting in 1964.
