Sporty drivers were especially smitten with this version with its impressive rear spoiler. The letter 'L' was important for this car. It stood for 'light alloy' and referred to the bodywork of aluminum and windows from plexiglass.. The reason for this expenditure was the homologation to group 2, which BMW wanted to manage with a car as competitive as possible. Missing front bumpers and rear bumpers of plastic also went along this line.
The engine power for racing could reach double that of the series, later with turbo-application even more. Indeed, these engines had 3.2 or 3.5 liters of cubic capacity. But the specific times can be achieved by the so far relatively unknown rear wings. This includes the deflecting spoiler on the roof and of course one front. Depending on the curvy route, the more it affects the drift, and thus all the competitors superior roadability. With an even larger wing and broader tyres, the car drives in the American IMSA series.
