Platform Heritage

The BMW 2 Series is a range of subcompact executive cars (C-segment) manufactured by BMW since the year 2014. The 2 Series was created when BMW spun-off the 2-door models (coupé and convertible) of the BMW 1 Series into a separate series. The 2 Series was first launched as a 2-door coupé and convertible, both based on a rear-wheel drive platform. A year later, the Active Tourer 5-seat compact MPV body style was added, based on the unrelated front-wheel drive platform shared with the Mini Countryman. This was followed by a 7-seat version called the Gran Tourer. In 2019, the Gran Coupé fastback sedan joined the 2 Series family as a front-wheel drive vehicle based on the 1 Series hatchback and has been marketed as a 4-door coupe. In 2021, BMW released the second-generation 2-door coupé, rear-wheel drive 2 Series in July 2021. The BMW M2 is the high-performance version of the 2 Series 2-door coupé. The first generation of the M2, the F87 coupé, was introduced in 2016 and featured the BMW N55 turbocharged inline-six engine.
