Updated four and six-cylinder
engines with 48V mild hybrid tech

(February 1, 2024) Driving pleasure and elegantly sporty design. These have been hallmark brand values of BMW since its earliest days, and the new BMW 4 Series Coupe and BMW 4 Series Convertible embody them even more keenly than ever. The 2-liter 4-cylinder and 3-liter 6-cylinder TwinPower Turbo engines benefit from 48V mild hybrid tech to improve efficiency and responsiveness.

The precisely modified exterior design of the two models underscores their dynamic character and exclusive style. The cutting-edge cockpit design provides the ideal stage for the latest evolution of BMW iDrive with QuickSelect, which is based on the new BMW Operating System 8.5.

New exterior paint finishes and light-alloy wheel designs, revised grilles, headlights with a striking design, and the new rear lights with laser-lit accents mark the latest advances in the exterior of the two models. Step inside the sporting two-door models and key new features of the cabin are immediately apparent with new steering wheel designs, and new interior trim elements.

Production of the new BMW 4 Series Coupe and Convertible will remain at BMW Group Plant Dingolfing. The worldwide market launch will get underway in March.

The Coupe begins at $51,695 including destination for the 430i and $59,695 for the convertible. The M440i coupe begums at $65,250 and the M440i convertible starts at $73,245.

The new 2 3-liter inline 6-cylinder engines in the 2025 M440i models feature a new 48V mild hybrid (MHEV) technology for sharper power deliver and greater efficiency. The auxiliary electric drive of the 48V starter generator can provide 11 hp of boost to the 375 hp TwinPower Turbo engine, resulting in  a total system output of 386 hp @ 5,200-6,250 rpm and 398 lb-ft of torque @ 1,900-4,800 rpm.

The  2-liter inline 4-cylinder engine in the 2025 430i also benefits from 48V mild hybrid technology, as well as incorporation of the Miller cycle combustion process, a redesign of the intake ports and combustion chambers, and innovations in the areas of camshaft control, injection, ignition system, and exhaust gas routing. The TwinPower Turbo 4-cylinder engine produces 255 hp @ 4,700-6,500 rpm, and 295 lb-ft of torque @ 1,600-4,500 rpm.

Design cues specific to the BMW 4 Series include the visually powerful front end shaped by slim LED headlights and a vertically arranged BMW kidney grille. The air intakes of the striking forward-angled grille have a mesh structure on 430i models, both in standard form and if the M Sport package is specified. The surround is now finished in matte chrome.

The new BMW 4 Series Coupe and Convertible also feature visually and functionally upgraded headlights. The LED units in their inner workings, which provide all the light functions, have been redesigned and have a new structure. Low and high beam lighting is generated from a single LED module. And a pair of vertical arrow-shaped LED units house the side marker light, daytime driving light, and turn signal indicator functions. The technically focused look of the new light sources gives the headlights a sophisticated, progressive appearance.



The LED headlights are paired with the visually and technologically impressive design of the Laserlight taillights, which are standard on M440i models and part of the optional Shadowline Package on 430i models. These units feature laser diodes illuminating glass fiber bundles, producing attractive 3-dimensional light graphics which complement the taillight clusters.

Standard sport seats and newly designed steering wheels add to the pleasure of the driving experience in the new BMW 4 Series Coupe and Convertible. High-quality, well- crafted materials and a new operating concept for ventilation and climate control systems add to the cockpit’s premium allure. The changes carried out to the interior of the new BMW 4 Series Coupe and Convertible ensure those on board can enjoy driving pleasure with progressive style and long-distance comfort in an ambience of carefully honed refinement.

The introduction of BMW iDrive 8.5 with QuickSelect brings improved operation of the ventilation and climate control functions in the new BMW 4 Series Coupe and Convertible. Temperature, fan speed, and seat and steering wheel heating (when equipped) can now be adjusted by touch via the BMW Curved Display or by voice command with the help of the BMW Intelligent Personal Assistant. New adjustment controls for the air vent grilles in the center of the instrument panel and on the driver’s and front passenger’s side of the cockpit allow the direction of airflow to be adjusted using rotating and tilting movements.

The standard ambient lighting in the new cars now also includes contour lighting integrated into the trim around the central vents. Like the lighting for the footwells, the storage compartment in the front section of the center console, and the door handles, this can be adjusted for color and brightness according to personal preference. The functionality of the interior lighting also includes an atmospheric Welcome and Goodbye Animation and light signals indicating an open door or incoming phone call.
