The three concepts aren't too slow, either. All three make their way from 0 to 62 mph in less than 11 seconds.
The BlueZero E-Cell employs a lithium-ion battery-electric drive that has a range of 120 miles. With a charging capacity of 7 kW, the electrics in the BlueZero E-Cell and the BlueZero E-Cell Plus can be recharged in two to four hours for a range of 120 and 240 miles, respectively. The semi-transparent roof lets 20 percent of the light into the interior and, with its solar panels, can generate enough power to charge a cell phone or MP3 player.
A 1.0L three-cylinder turbo from the smart fortwo extends the range of the BlueZero E-Cell Plus to 370 miles. The F-Cell -- the fuel-cell powered concept -- has a range of over 240 miles.
