The overall design is driven by functionality and each detail has its purpose. The Liquid Orange paintwork exclusively developed for the BMW M1 Homage cites the classic BMW M1 colour, yet surprises with its powerfully iridescent play of colour and brilliant depth. It shapes the extrovert surface language and strikingly highlights the eloquent interplay of convex and concave surfaces. A telling symbol of this is the kidney grille design of the BMW M1 Homage, fulfilling as it does several functions at the same time.
The twin kidney isn't just a signature BMW feature, it is also part of the car's honed aerodynamics: it guides the air to the engine cooling as well as constituting the front section of a crash box, similar to the monocoque chassis of a Formula One race car. Mention the BMW M1, and another feature that immediately springs to mind is the characteristic twin logo at the rear, on the right and left edge above the tail lights. For BMW, this particular arrangement of its emblems has always signalled a mid-engined model. In the development stage of the BMW M1 this dual emblem was the first styling element to be approved even before the initial sketches were drawn. Other specific styling cues taken from the BMW M1 are the air vents in the bonnet and the louvres on the rear windscreen, as well as the black cutline dividing the roofline from the rear section of the body. Overall, the exterior dimensions of the BMW M1 Homage are in keeping with those of the BMW M1; only the extended wheelbase indicates a larger passenger cell. The cooling air routing for the engine is positioned below the roofline, in the black recessed cutline along the side of the vehicle behind the window graphic. Small flaps and openings guide the air stream into the engine compartment to ensure an adequate supply of cooling air.
