The company claims a top speed of 120 km/h (74 mph) and a range of 110 km (68 miles) for this high performance car. The entire top of the Astrolab is covered with 3.6 square meters of photovoltaic cells and "by a film composed of nano-prisms enabling denser concentration of solar energy" to charge the batteries that supply power to the electric motor - even on the move. A full recharge of the batteries would take about 5 hours using a standard 16A plug. With a chassis built from carbon fibers and weighing 250 kg (550 lbs.) in all, the ultra-light tandem two-seater resembles a four wheel motorbike more than a car.
