The BMW 4 Series Gran Coupe will cost $500 more than its two-door Coupe sibling and at least $10K more than the 3 Series sedan when it reaches Australian showrooms in June.
BMW Australia will offer four grades of the third member of its all-new 4 Series family that is aimed squarely at Audi's A5 Sportback – 420i: $70,000, 420d: $72,300, 428i: $81,000, and 435i: $109,000 – each one asking an identical $500 premium over its equivalent 4 Series Coupe variant.
The jump is larger from the 3 Series sedan, however, with the 420i and 420d variants commanding a $10,000 premium over their equivalent sedans, the 428i $12,100 over the 328i, and the 435i $15,600 over the 335i sedan.
The 420i and 420d Gran Coupes are also $500 more than their equivalent 3 Series Gran Turismo models, while the 428i costs $4500 more than the 328i GT (BMW Australia does not offer a 335i GT).
Sharing the Coupe’s 4638mm length, 1825mm width and 2810mm wheelbase, the key differentiator of the BMW 4 Series Gran Coupe is its roofline, which sits 12mm higher and extends 112mm further towards the rear of the car.
The two frameless rear doors open up to the only three-seat second row in the 4 Series range, though BMW admits the middle seat of the ‘2+1’ configuration is intended for occasional use only. The raised roofline creates more headroom for rear-seat passengers.
The 4 Series Gran Coupe’s 480-litre boot betters that of the Coupe by 35L and matches the 3 Series sedan but trails the 3 Series GT by 40L. It expands to 1300L with the 40:20:40 split-fold rear seats pushed forwards.
The four engines in the BMW 4 Series Gran Coupe range are identical to those powering the Coupe.
The 420i and 428i are powered by a turbocharged 2.0-litre four-cylinder petrol engine. The former produces 135kW and 270Nm, claims 0-100km/h acceleration of 7.6 seconds and combined cycle fuel consumption of 6.1 litres per 100km; the latter 180kW, 350Nm, 6.0sec 0-100km, and 6.4L/100km.
The sole diesel, the 420d, produces 135kW and 380Nm from its 2.0-litre four-cylinder turbo diesel engine, claims a 7.5sec sprint and combined consumption of 4.6L/100km.
The flagship 435i features a turbocharged six-cylinder engine with 225kW and 400Nm, claims to sprint to triple figures in 5.2sec, and use 7.6L/100km combined.
All models are equipped with stop-start engine technology and the brand’s eight-speed Sports Automatic transmission.
The specification of each Gran Coupe variant is almost identical to its equivalent Coupe, though the Gran Coupes gain an automatic tailgate as standard.
The new body style also scores an inbuilt SIM card to enable the full suite of BMW ConnectedDrive features for the first time in Australia, including functions such as emergency call and real-time traffic information.
