Dressed in heavy camouflage, the prototype doesn't reveal much but recent patent filings have shown the production model will closely resemble the Concept Active Tourer but adopt a revised front fascia with more conventional headlights. We can also expect a new rear bumper, larger taillights and a traditional exhaust system.

Under the hood, we can expect a variety of three- and four-cylinder engines. Detailed specifications haven't been released but BMW has previously stated their 1.5-liter TwinPower Turbo three-cylinder will have outputs ranging from 82 HP (60 kW) to 224 HP (165 kW).

The 2014 BMW 1-Series GT could be unveiled at the Geneva Motor Show, but nothing is official as of yet.
