Signature BMW driving pleasure and sporting elegance brought together with modern functionality: The new BMW 4-Series Gran Coupé is poised to build on the success of its predecessor with this blend of qualities plus well-conceived enhancements to its inherent attributes and product substance. Like its freshly updated BMW 4-Series siblings, the third body variant in the range also makes its mark with notably improved driving dynamics, sharper looks following the brand’s new design language, a refined premium ambience in the cabin and a wide array of innovations in the areas of control/operation and connectivity. Four doors, five full-size seats, a large, wide-opening tailgate and a versatile luggage compartment also help to ensure the new BMW 4-Series Gran Coupé retains its characteristic strengths in both everyday driving and on longer trips.
The latest-generation models in the BMW 4-Series range stand out as premium midsize vehicles with distinct characters all of their own. Their even greater dynamic prowess and exclusive aura are the fruit of measures to sharpen their profile and clearly distinguish them from the BMW 3-Series Sedan that served as the technological blueprint. Like its siblings, the new BMW 4-Series Gran Coupé proudly proclaims this individual positioning with its exterior design. Its dynamically stretched silhouette, four doors, distinctive proportions, flowing roofline and the clean-cut, reduced surface design in the new BMW styling language exude coupé-style elegance, supreme sporting flair and an air of functionality specific to this model. Moving inside the new 4-Series Gran Coupé, these harmoniously combined qualities are brought to the fore most notably by the driver-centric cockpit design and the impressive spaciousness in the rear. The five seats – with standard folding head restraints in the rear – feed into a premium ambience brimming with elegance and modernity, one whose high-quality materials and precision workmanship represent a convincing proposition.
The standalone character of the new BMW 4-Series Gran Coupé is rounded off by the modern functionality of its overall concept. Measuring 4,783 millimetres in exterior length, 1,852 millimetres in width and 1,442 millimetres in height, it has dynamic coupé proportions. It is 143 millimetres longer, 27 millimetres wider and 53 millimetres taller than its predecessor, while the track widths have also grown – to 1,595 millimetres at the front (+50 mm) and 1,623 millimetres at the rear (+29 mm). This is also an increase on the track widths of the new BMW 3-Series Sedan of 6 and 19 millimetres respectively. The wheelbase of 2,856 millimetres is 46 millimetres longer than the predecessor’s and 5 millimetres more than the figure for the 3-Series Sedan. The standalone Gran Coupé body concept results in a versatile interior offering generous amounts of space in the rear, where occupants will find three full-size seats awaiting them and considerably more legroom and headroom than in both the outgoing model and the new BMW 4-Series Coupé. The new BMW 4-Series Gran Coupé offers 470 litres of boot space, the primary capacity in the directly viewable area of the boot having grown by 39 litres. Load space can be expanded to a maximum of 1,290 litres by folding down the sections of the rear backrest, with its standard 40 : 20 : 40 split.
Upgraded BMW TwinPower Turbo technology has also enhanced the performance characteristics of the 2.0-litre four-cylinder petrol engines. The more powerful of the duo has an exhaust manifold integrated into the cylinder head for the first time, resulting in extremely effective exhaust cooling for even cleaner emissions. It generates maximum output of 180 kW/245 hp and peak torque of 400 Nm (295 lb-ft), enabling the new BMW 430i Gran Coupé to accelerate to 100 km/h (62 mph) from rest in 6.2 seconds. The engine’s optimised efficiency levels result in combined fuel consumption of 7.6 – 6.8 l/100 km (37.2 – 41.5 mpg imp) and emissions figures of 173 – 156 grams per kilometre in the WLTP cycle. Two-stage turbocharging and updated common-rail direct injection technology endow the 2.0-litre diesel unit in the BMW 420d Gran Coupé and BMW 420d xDrive Gran Coupé with superior pulling power and efficiency. The engine produces output of 140 kW/190 hp and maximum torque of 400 Nm (295 lb-ft). The instantaneous flow of power results in 0 to 100 km/h (62 mph) sprint times of 7.3 seconds for the new BMW 420d Gran Coupé and 7.6 seconds for the new BMW 420d xDrive Gran Coupé. The two models post combined fuel consumption and CO2 figures in the WLTP test cycle of 5.4 – 4.8 l/100 km (52.3 – 58.9 mpg imp) and 141 – 126 grams per kilometre (BMW 420d Gran Coupé) and 5.7 – 5.1 l/100 km (49.6 – 55.4 mpg imp) and 150 – 133 grams per kilometre (BMW 420d xDrive Gran Coupé).
The four-cylinder engine in the new BMW 420i Gran Coupé is another shining example of efficiency and the free-revving performance associated with BMW power units. Its maximum output of 135 kW/184 hp and peak torque of 300 Nm (221 lb-ft) translate into a 0 to 100 km/h (62 mph) time of 7.9 seconds. Average WLTP fuel consumption comes in at 7.3 – 6.6 l/100 km (38.7 – 42.8 mpg imp) with CO2 emissions of 166 – 150 grams per kilometre. This concept of a four-door coupé for the premium midsize segment has seen the compelling blend of elegantly sporty design and hallmark BMW driving pleasure win over new customers. In fact, the BMW 4-Series Gran Coupé has become a true ambassador of these traditional BMW qualities, establishing itself – in the space of a single model generation – among the three models making the greatest contribution to brand image. The new edition of the BMW 4-Series Gran Coupé will be built at BMW Group Plant Munich together with the all-electric BMW i4. Assembly of both at the company’s home plant will be almost entirely integrated into the manufacturing process developed for the BMW 3-Series Sedan and BMW 3-Series Touring models. The market launch of the new BMW 4-Series Gran Coupé will get underway in November 2021.
