Among the subtle exterior design changes to BMW’s entry-level two-door models are a wider kidney grille, new LED headlights, revised tail-light lens graphics and redesigned alloy wheels ranging from 16 to 18in.
Inside, the Coupé and Cabriolet also get a lightly altered dashboard with redesigned instruments and an updated 8.8in touch-operated display supporting a revised operating system for the iDrive infotainment system.
The subtlety of the facelift is reflected in the engine line-up, which remains the same as before; the petrol units range from a 134bhp in the base 218i to 335bhp in the top of the line M240i, while the diesels extend from 148bhp in the 218d to 221bhp in the 225d.
Buyers can choose between a standard six-speed manual or an optional eight-speed automatic gearbox in most models.
Alongside standard rear-wheel drive, the more powerful engines can also be allied to an optional xDrive four-wheel drive system.
At the top of the line-up is the facelifted M2. It benefits from the detailed design revisions brought to the exterior and interior of less powerful versions of the 2-series Coupe, while retaining the same 365bhp turbocharged 3.0-litre in-line six-cylinder petrol engine as before.
Prices for the various 2018-model-year 2 Series Coupé and 2-series Cabriolet models are yet to be made official, though BMW officials suggest they will remain close to the current prices, which start at £23,530 for the 218i SE Coupé and rise to £35,865 for the M240i.
