Last week the company revealed that it has covered 218,000 test miles (350,000 kilometers) in its Quantino 48Volt test car, 125,000 on the road and 93,000 in a test lab. The company first showed its Quant cars at the 2014 and 2015 Geneva shows, first the gull-wing Quant E limousine, then the smaller, sporty Quantino the next year.
