With its precise control and short shifts, the obligatory manual transmission perfectly underscores the purist, sporty character of the BMW 1 Series M Coupe.
The compact six-speed transmission with dry sump lubrication is a new development and has a weight of just 43 kg – much lighter than similar gearboxes.

Applying the marketing speak filter, this could very well be an existing transmission with modifications. Fi to the lower cast (material) and/or other internal oil recirculation particulars, to improve the lubrication under horizontal acceleration.
Does anyone know what other BMW transmissions weigh in compared to the 43 Kg?
