The 2010 Geneva Motor Show will open its doors tomorrow and one car that we’ve been waiting for months to make its world debut is the new 2011 Audi A1 premium compact car. We’ve just about seen as many videos, promos, teasers, and spy shots of the car that the only thing left is to see it live and in the flesh.

What we don’t know, however – and what a French website is now reporting – is that the A1 may come in another version that aren’t of the gas and diesel engine variety.

According to this report, Audi is toying with the idea of using an A1 to be the basis of another E-Tron concept->ke3605, following in the R8-based E-Tron concept that we saw in Frankfurt last September. While the R8-based E-Tron will only be built with a limited number, there’s a distinct possibility that an A1-based E-Tron could become Audi’s flagship volume plug-in vehicle, which, if you think about it, is a pretty smart move by Audi. Introducing a car that’s bound to get a lot of attention from customers would end up being more attractive if it came with a more fuel-efficient engine variant that the traditional petrol and diesel variety.

In any case, we’re going to have all these reports and rumors answered soon enough when the Geneva Motor Show officially opens tomorrow.
