If you remember earlier, BMW promised there would be a car on display at the 2007 Tokyo Motor Show based on the 1 Series chassis, and some speculated it to be perhaps the X1 or an M-badged 1-Series. At the press day today at the motorshow, BMW unveiled the BMW Concept 1 Series tii, a design study based on the 1 Series.

The BMW Concept 1 Series tii is an interpretation of classic BMW brand values, with specific motorsport requirements taken into account in the design of the car. BMW says they emphasized on agility, lightness, youthfulness and superior sportiness when designing the car.

On the exterior, body aerodynamics is optimised with the front air dam design, side-sills and rear air dam. Special wickerbills generate additional downforce on the rear axle. Weight has been reduced through the usage of lightweight engineering and carbon fiber components such as the bonnet, mirror caps, and front air intake inlays. There is no usual vertical bar kidney grilles on the Concept 1 Series tii, instead air flows into the engine bay through a wide honeycomb grid.

On the interior some of the enhancements you have are the sports bucket seats with integrated headrests and side airbags, three-spoke sports steering wheel, and a gearshift knob with alcantara cover. The use of dark alcantara on the door linings and instrument panel prevents reflections on the windscreen. For this concept, the meter panel’s rev counter now has a white face.
