For a car that doesn't yet exist, it has a solid marketing plan. The Financial Times reports that Audi is targeting its rumored all-electric A2 toward megacities with populations of more than 5 million people.

And, of course, there will be an app store.

The hypothetical app store will let A2 owners download upgrades for their car from the comfort and convenience of their home, Peter Schwarzenbauer, Audi's head of marketing and sales, told the Financial Times. The apps will let drivers customize their car's interior, driving style, as well as add features.

Potentially, Audi may construct the A2 using lightweight, expensive materials such as magnesium and carbon fiber, making the proposed A2 a "futuristic interpretation of urban mobility." A car clearly before its time, Audi scrapped the original A2 in 2005 because of lack of demand for it.

There's no word on if or when the funky e-car will make it stateside, but the Audi executive said it is conducting a focus group in New York, among other cities, to gauge consumer demand.
