We’re not too sure about this one as of yet, as details are a bit scant. But here we go: VW is promising to bring us the VW 1L in 2010. What is the 1L? It’s a 2-seater toboggan-style car (one in front of the other) with a plastic/magnesium shell and all-glass roof that uses only 1 liter of gas to go 100 km (230 miles per gallon) while hitting speeds of up to about 75 MPH. More details as they come.
