When the Volkswagen Group starts building its "new small family" NSF micro cars in a couple of years, there will be variants for most of its mainstream brands. That includes Audi, which is likely to use the ultra compact platform to kick off a new E series of models starting with the E1. The E1 will be built with other NSF models at Volkswagen's Bratislava, Slovakia factory.

While the E-series cars will be aimed at maximizing efficiency, they will still offer a variety of powerplants including turbocharged 600 cc two cylinder engines running on either gas or diesel. Those will be joined by both hybrid and all-electric versions using lithium polymer batteries.

The original VW up! concept was a four-seater (barely!) but the production model may only be a 2+1 or perhaps 3+1 like the Toyota iQ. The 600 cc E1 should easily get CO2 emissions of under 100 g/km when it launches in 2011.
