What’s the best way to stick it to owners of gas-guzzling SUVs? Turn up at your local off-road track in a new MINI 4x4 crossover and show them how yesterday big truck based SUVs really are. That’s the possibility if BMW gives the green light to an off-road version of the MINI based on the Traveller five-door wagon.

The UK’s AutoExpress is reporting that an all-wheel-drive MINI is being developed alongside several other variants. According to a Deep Throat inside BMW, the dominant US market favors a small SUV/crossover version and that there’s idle capacity at the company’s Spartanburg plant in South Carolina. Other models include pickup and four-door wagon versions.

The insider also slipped that the US would likely overtake the UK in sales of the MINI if there were models, stating “we have many concepts which may or may not become realities, but there is a strong brand and sales-generating logic behind a MINI 4x4 crossover, particularly as the USA could soon overtake the UK as a market." The 4x4 would likely hit showrooms in 2010.
