Mild hybrid technology, the latest weight-saving chassis technology and the first BMW to be available with the specialised M Sport Pro Package, form part of the offering in the all-new BMW 4 Series Coupé. The new BMW 4 Series Coupé will be built at BMW Plant Dingolfing, with its worldwide launch commencing in October 2020.

Distinctive exterior design
At 4,768 millimetres, the new car is 128mm longer than its predecessor and 27mm wider (now 1,852mm), and its wheelbase has grown by 41mm to 2,851mm. Only 6mm has been added to the vehicle height, which is now 1,383mm. Increased track widths (+ 28mm at the front and + 18mm at the rear), short overhangs, slender pillars, long doors with frameless windows and a flowing roofline combine to deliver what BMW describes as a sleek look.

Full-LED headlights are fitted as standard, with two U-shaped fibre-optic light guides in the lower section serving as the daytime driving lights. Adaptive LED Headlights with BMW Laserlight, including BMW Selective Beam non-dazzling high beam assistant, are available optionally. Slim LED fog lights are standard on all models except the BMW M440i xDrive Coupé and BMW M440d xDrive Coupé.

M Sport model format
The new BMW 4 Series Coupé can be ordered in M Sport model format. Large outer air intakes in the front apron and a striking rear apron with an inlay in Dark Shadow and a diffuser element in High-gloss Black showcase the two-door model’s performance credentials. Other M Sport model design features are air intake trim elements, side window surrounds and exterior mirror bases in High-gloss Black.

As well as the body features in the M Sport model, the BMW M440i xDrive Coupé and BMW M440d xDrive Coupé also come with a kidney grille surround, air intake trim, exterior mirror caps, trapezoidal exhaust tailpipe finishers in Cerium Grey metallic, and a rear apron inlay in High-gloss Black.

Premiere for M Sport Pro package, wide choice of model-specific M Performance Parts
The BMW 4 Series Coupé two-door model is also the first BMW to be made available with the new M Sport Pro package.

This option includes all the elements of the M Sport model and adds the Sprint function for additional bursts of speed and a sporty engine soundtrack in the cabin when SPORT mode is activated. In addition, the M Sport brakes are featured on the BMW 420i Coupé, BMW 420d Coupé and BMW 420d xDrive Coupé, as well as 19-inch M light-alloy wheels, a rear spoiler in High-gloss Black, BMW Individual High-gloss Shadowline trim with extended features and BMW Individual lights Shadowline and M seat belts.

Introduction of the 4 Series M Sport Pro Edition
Building on the M Sport model, the new M Sport Pro Edition combined the M Sport Pro package with a choice of 3 exclusive Individual Metallic exterior paints – Dravit Grey, Tansanite Blue and Aventurin Red (07/21). The new edition gains unique 19-inch Jet Black Double Spoke wheel, Black High Gloss Mirror Caps and the choice between Individual Aluminium Fabric High Gloss or Piano Black interior trim.

Engines
The powertrain technology developed for the new 4 Series Coupé is another area where BMW says that significant advances have been made over the outgoing model. All the petrol and diesel engines belong to the Efficient Dynamics family and feature BMW TwinPower Turbo technology. The company says the introduction of mild hybrid technology with a 48V starter-generator ensures even sharper power delivery combined with reduced fuel consumption and emissions.

The range will be spearheaded by a new BMW M440i xDrive Coupé model, which features a six-cylinder in- line petrol engine. The new BMW 4 Series Coupé will also be available with a choice of two four-cylinder petrol units and a four-cylinder diesel from launch. The line-up is set to expand further with the arrival of two straight-six diesel engines scheduled for March 2021.

All the engines link up as standard with the eight-speed Steptronic transmission, which can now be specified with the new optional Sprint function. BMW xDrive is also available on the four-cylinder diesel model, while the all-wheel-drive system features as standard on all six-cylinder variants.

Mild hybrid technology
Mild hybrid technology has been included with all diesel engines and with the straight-six petrol unit of the flagship BMW M440i xDrive Coupé. Fitting a 48V starter-generator and second battery increases the scope for utilising Brake Energy Regeneration and the electrical power it produces.

The recuperated energy collected by the 48V battery can be supplied to the 12V electrical system or used for generating additional drive power when fed back to the 48V starter-generator. When the car is accelerating, the generator is also able to offer the driver an electric boost effect that instantly makes an extra 11 bhp available.

New: two-stage turbocharging for all diesel engines
A new two-stage turbocharging system now forms part of the BMW TwinPower Turbo technology integrated into all diesel engines for the new BMW 4 Series Coupé.

The 2.0-litre four-cylinder diesel unit in the BMW 420d Coupé and BMW 420d xDrive Coupé additionally uses an advanced version of the common-rail direct injection system. The engine generates maximum output of 187 bhp and peak torque of 295 ft lb, enabling a 0-62mph sprint times of 7.1 seconds (BMW 420d Coupé) and 7.4 seconds (BMW 420d xDrive Coupé). Efficiency has likewise improved, with combined fuel consumption of 67.3 – 72.4mpg and CO₂ emissions of 112 – 103 g/km for the new BMW 420d Coupé, and 61.4 – 65.7mpg and 121 – 112 g/km for the BMW 420d xDrive Coupé.

Multi-stage turbocharging technology also features in the 3.0-litre six-cylinder in-line unit powering the new BMW 430d xDrive Coupé (due to become available from March 2021). The turbocharging system’s variable turbine geometry is designed to ensure a high level of responsiveness, with 475 ft lb of peak torque on tap. Maximum output is 28s bhp, allowing the car to accelerate from 0-62mph in 5.2 seconds.

The new BMW M440d xDrive Coupé (due in March 2021) features a straight-six, 3.0-litre diesel engine producing 335 bhp. Peak torque, meanwhile, has increased to 516 ft lb. For optimum response and power delivery, the new power unit’s high-pressure and low-pressure stages both feature variable turbine geometry. The new BMW M440d xDrive Coupé requires just 4.7 seconds to reach 62mph from rest.

Standard on all models: eight-speed Steptronic transmission
This is the first time that every BMW 4 Series Coupé has been fitted with an eight-speed Steptronic transmission as standard. The latest version of the automatic transmission has been revised to provide sharper shift characteristics with greater efficiency and refinement. All models are fitted with shift paddles on the steering wheel.

Besides the Launch Control function for traction-optimised acceleration off the line, the eight- speed Steptronic Sport transmission is also the first to feature the brand-new Sprint function, designed to maximise performance when putting in a sudden burst of speed or overtaking. The Sprint function features as standard in the BMW M440i xDrive Coupé and BMW M440d xDrive Coupé and is available for all other model variants in conjunction with the M Sport package Pro.

BMW Operating System 7
With the inclusion of BMW Operating System 7 in the new BMW 4 Series Coupé, individually configurable display content and intelligent connectivity “underpin seamless interaction between driver and vehicle”.

The enhanced intuitive multimodal interaction allows the driver to take their pick of control interface for the situation at hand: Control Display touchscreen, proven iDrive Controller, multifunction buttons on the steering wheel, voice control or optional BMW gesture control.

The standard BMW Live Cockpit Professional, offers a fully digital screen grouping comprising a high-resolution 12.3 inch instrument cluster behind the steering wheel and a 10.25-inch Central Control Display. Connected Package Professional is included on all models, comprising BMW TeleServices, Intelligent Emergency Call, Real Time Traffic Information with hazard warning, Remote Services and Concierge Services and more.

BMW Intelligent Personal Assistant and Connected Music are offered standard on the new BMW 4 Series Coupé, as are additional new enhancements to navigation and parking digital services.

The switch to BMW Operating System 7 also brings the Remote Software Upgrade function to the new BMW 4 Series Coupé, keeping the vehicle up to date with the latest software. All updates can be imported over the air, either on a smartphone via BMW Connected or directly into the car using its built-in SIM card.
