Platform Heritage

The BMW X1 is a line of cars produced by German marque BMW since 2009. It is in the subcompact luxury crossover class, and the first-generation X1 was based on the E90 3 Series and offered rear-wheel drive layout as standard. The X1 essentially is aiming at a wider range of customers due to its smaller size, increased efficiency, and a lower price tag due to the all-wheel drive layout (xDrive) being optional. The second-generation X1 introduced a plug-in hybrid option and marked the switch to a front-wheel-drive-based layout using the UKL2 platform shared with the BMW 2 Series Active Tourer and the Mini Countryman. Despite its name, it is now only the second smallest SUV produced by BMW since the introduction of the X2. The third and current generation was released in 2022 and introduced a mild hybrid powertrain.
