ALL AUTOCARS

VW's first up! concept made its debut at the 2007 Frankfurt Auto Show in September. That one was a two-door city car that put viewers in mind of the Smart Fortwo.

Now the second one- space up! is a four-seater van concept with four doors, although VW says, "in actuality there are even six" because it has a two-part rear door instead of a tailgate. The rear bench seat has two integrated child safety seats and can be removed, as can the front passenger seat.

The space up! is 60.6 inches in length and rides on a 100.8-inch wheelbase. It's 9 inches longer than the up! concept shown at Frankfurt. It is the bigger than the Volkswagen Beetle.
