Although introduced in the Paris Motor Show in 2006, the Venturi Astrolab was spotted again at the EVER Salon in Monaco (Green Cars Autoshow). The concept, which showed an interesting tandem lightweight (only 280 kg!) architecture, was designed to provide the maximum surface available to recharge the car's batteries.
As you might know, because of the focus that European countries are putting on CO2 emissions, most marques have created signature labels to certify when a certain vehicle is "clean" in the environmental sense. They basically take the least powerful version of the model, tweak the car aerodynamically, and install low-rolling resistance tires. Then they chose a fancy name.
