📖BMW 2 Series Convertible F23 (2015-2017): an agile rear-wheel-drive convertible requiring strict roof drainage and cooling upkeep

BMW 2 Series Cabriolet F23 (2015-2021)

Arriving in early 2015 to succeed the 1 Series Convertible, the BMW 2 Series Convertible F23 enhanced the compact open-top formula with 20% greater torsional rigidity and superior acoustic insulation. Retaining authentic rear-wheel drive and a multi-layer fabric soft-top capable of operating at up to 30 mph, it offered pure top-down driving pleasure. Keeping an F23 cabriolet in top condition requires regular BMW 2 Series maintenance, particularly regarding roof mechanics and running gear.

Powertrains transitioned from early N20/N55 engines to the superior modular B48 four-cylinder (220i, 230i) and glorious B58 six-cylinder (M240i). The engines pair brilliantly with the acclaimed eight-speed ZF automatic transmission or a six-speed manual. Key mechanical watchpoints include plastic coolant hose connectors and the oil filter housing on early B48 engines.
