BMW M440i Gran Coupe [UK]
The new BMW 4-Series Gran Coupé is a car that delivers on so many fronts, combining sporting elegance with driving pleasure and, with five full-size seats, a roomy cabin and a versatile luggage area, it also represents modern functionality that is hard to emulate.
BMW has raised the bar even higher with the new BMW 4-Series Gran Coupé, building on the success of its predecessor. The latest version offers even sharper looks, improved driving dynamics, a superior engine line-up and even more interior space.
Like its recently updated BMW 4-Series siblings, the third body variant in the range adopts the brand’s new design language, along with 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 boot and a versatile luggage compartment also ensures the new BMW 4-Series Gran Coupé retains its characteristic strengths in both everyday driving and on longer trip.
Measuring 4,783mm long, 1,852mm wide and 1,442mm in height, the new BMW 4-Series Gran Coupé has dynamic coupé proportions but it is 143mm longer, 27mm wider and 53mm taller than its predecessor, while the track widths have also grown to 1,595mm at the front (+50 mm) and 1,623mm at the rear (+29 mm). This is also an increase of 6mm and 19mm respectively on the track widths of the new BMW 3-Series Saloon. The wheelbase of 2,856mm is 46mm longer than the predecessor’s and 5mm more than the 3-Series Saloon.
Choice of rear-wheel drive or xDrive diesel models
Two-stage turbocharging and updated common-rail direct injection technology feature in the 2.0-litre diesel unit in the BMW 420d Gran Coupé and BMW 420d xDrive Gran Coupé. The engine produces 190hp and maximum torque of 400Nm, allowing 0 to 62mph 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 of up to 58.9mpg and 55.4mpg respectively.
Efficient four-cylinder petrol engines in the BMW 430i Gran Coupé and BMW 420i Gran Coupé
Upgraded BMW TwinPower Turbo technology has also enhanced the performance 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 245hp and peak torque of 400Nm, enabling the new BMW 430i Gran Coupé to accelerate to 62mph from rest in 6.2 seconds. Its efficiency translates into fuel economy of up to 41.5mpg.
The four-cylinder engine in the new BMW 420i Gran Coupé produces 184hp and peak torque of 300Nm, giving it a 0 to 62mph time of 7.9 seconds. Fuel economy can be as much as 42.8mpg.
Trio of advanced petrol engines
The trio of petrol engines available for the new BMW 4-Series Gran Coupé feature a twin-scroll turbocharger, a High Precision Injection system whose maximum pressure has been upped from 200 to 350 bar, VALVETRONIC fully variable valve timing and Double-VANOS variable camshaft timing, along with cooling and oil supply systems that are now more efficient. Petrol particulate filters have been added to improve their system of emission control.
The six-cylinder in-line unit powering the BMW M440i xDrive Gran Coupé was developed with the racetrack expertise of BMW M GmbH and comes with weight-optimised pistons and con rods as well as a twin-scroll turbocharger with indirect charge air-cooling. It generates maximum output of 374hp from its 3.0-litre displacement with torque peaking at 500Nm. It can sprint from 0 to 62mph in 4.7 seconds yet also return more than 35mpg. Its power is complemented by the distinctive-sounding standard M Sport exhaust system.
Optimised aerodynamics and intelligent lightweight design
The new BMW 4-Series Gran Coupé body includes numerous measures that optimise its aerodynamic properties and have a beneficial effect on both driving dynamics and efficiency. An active air flap control system comprising flaps at the top and bottom, air curtains, streamlined light-alloy wheels and an almost completely sealed underbody serve to channel the airflow effectively. The drag coefficient (Cd) of 0.26 measured for the BMW 420d Gran Coupé, for example, represents a reduction of 0.02 over its predecessor.
An intelligent mix of materials helps to lower vehicle weight and combines with optimised load paths to enhance the body’s rigidity and crash safety. The hot-stamped steels and aluminium alloys used for the safety passenger cell are supplemented by multi-phase steels for extra reinforcement.
The front end of the car uses an engine side member made from extruded aluminium profiles and die-cast aluminium spring struts. Other advances over the outgoing model have been achieved through the aluminium construction of the bonnet and front side panels of the new BMW 4-Series Gran Coupé.
