Set to go on sale in the UK in June with prices starting from £29,420, the five-door liftback extends the 4-series line-up to three distinct body styles. It joins the 4-series coupé and convertible to create a range intended to rival that of the Audi A5.
The new car is similar in appeal to the 6-series Gran Coupé. However, BMW has turned away from using the conventional boot of that model, instead giving the 4-series Gran Coupé a more versatile five-door liftback arrangement, like that of the bigger, taller 3-series Gran Turismo. BMW officials say this format will make the 4-series Gran Coupé more appealing to younger buyers.
The result is a car similar in layout to the A5 Sportback, with a shallow glasshouse, two short rear doors (all of them frameless), a coupé-like roofline and a large liftback-style tailgate that opens automatically, either via the key fob or an optional foot-operated sensor incorporated into the rear bumper.
The 4-series Gran Coupé is 4638mm long, 1825mm wide and 1389mm tall. That’s 14mm longer, 14mm wider and 40mm lower than the 3-series saloon. Despite its sleek appearance, the drag coefficients are only average by class standards, with a best of 0.27 in 418d guise, rising to 0.30 on all-wheel-drive models.
