The BMW Concept M135i consistently utilises the dynamic potential of the new BMW 1 Series for the concept of the first BMW M Performance automobile featuring a straight six-cylinder petrol engine.
The employment of a straight six-cylinder petrol power plant featuring M Performance Twin Power Turbo technology with a power output of more than 223kW creates the ideal prerequisites for maximum dynamics in the premium compact segment and, in conjunction with rear-wheel drive concept still unique in this vehicle class, ensures unsurpassed driving pleasure so typical of a BMW.

Moreover, the characteristic handling precision of BMW M Performance automobiles is obtained through model-specific suspension technology that includes an M sports braking system and is perfectly adapted to match the supreme road performance. 18-inch Mlight alloys with a double spoke design additionally complement the concept car’s sporting character.
The front apron of the concept car boasts a typical M design, signaling intensive road-orientation, its large air intakes designed to match the cooling requirement of the powerful engine, ancillary components and large brakes. The three-dimensionally designed flaps on the air intakes give indication of the car’s direct association with motor racing.

In addition to intense road-orientation, the specific design of the rear end of the BMW Concept M135i emphasises above all the vehicle’s width. This is supplemented in particular by the three-dimensional modeling of the surfaces and the lower section of the rear apron finished in Dark Shadow metallic. Furthermore, the rear apron accommodates the exhaust system’s double tailpipe that features a dark chrome trim.
The BMW Concept M135i’s exterior mirror caps in Ferric Grey and side window surrounds in BMW Individual High Gloss Shadow Line are a further feature of BMW M Performance automobiles.
Compared with the silhouette of the five-door BMW 1 Series, the three-door BMW Concept M135i makes an even more sporting and elegant statement. On the whole, the car has a more dynamic and elongated appearance. Viewed from the side, the car’s low-slung appearance and its nearness to the road are even more intensely expressed by an entirely horizontal contour line in the area of the doorsills. A dynamically rising character line symbolises the BMW Concept M135i’s urge to move forwards.

The wide doors are a further characteristic feature of the BMW Concept M135i’s body design. Together with the rear side windows, the frameless windows form a coherent window surface reaching back to the rear end, accentuating the body’s dynamically stretched appearance.
