The BMW 4 Series coupe and convertible have both been given an update, introducing a range of changes to the popular four-seater. 


Arriving with customers in the spring of this year, the updated model will be priced from £43,020 for the coupe and £49,695 for the Convertible.


The most notable change is the condensed engine range, which consists of two mild-hybrid assisted petrol engine options connected to an eight-speed automatic. The diesel options have been dropped entirely.


The base 420i produces 182bhp and 300Nm of torque from its turbocharged 2.0-litre four-cylinder engine, powering the rear wheels only. This is enough to launch the car from 0-62mph in 7.5 seconds and go on to a 149mph top speed. 


The Convertible’s extra weight drops these figures to 8.2 seconds and 146mph. MPG figures top out at 53.3mpg and 49.6mpg for the coupe and convertible, respectively. 


Above this will sit the M440i, which features a 368bhp 3.0-litre straight-six petrol engine that’s also good for 500Nm of torque. In this case, power is sent to all four wheels and will sprint to 62mph in 4.5 seconds, or 4.9 for the Convertible. Despite the extra power, fuel consumption isn’t too heavily affected, with 41.5mpg and 40.9mpg figures for the coupe and convertible.


The mild-hybrid system adopts a 48V electrical system and compact battery to power a small electric motor. Generating 11bhp, the system can temporarily provide more performance when ‘Boost’ mode is engaged. 


The 420i models will be available in M Sport and M Sport Pro forms, while the M440i can be had with a more sporty, M Performance trim. 


Visually, BMW has fitted new LED headlights to the front end of the 4 Series, and the large kidney grilles which dominate the front end are now surrounded by chrome in a matt finish. 


To differentiate it from lesser models, the M440i has a series of additional styling tweaks, such as new horizontal bars within the grilles and black exhaust finishers.


Across the range, BMW is offering two new 19-inch wheel designs and two additional colours, while the convertible's fabric roof can be raised and lowered at speeds of up to 31mph in 18 seconds. 


The interior remains largely the same as the current 4 series, featuring an expansive, curved display running the firm’s latest iDrive infotainment system, and the air conditioning controls remain integrated directly into the screen. However, the air vents have now been reshaped, and can be boarded with a choice of aluminium or wood trim, or carbon fibre for the M440i. The steering wheel has also been updated featuring a flat bottom. 


The updated 4 series range is available to order now with customer deliveries due in the Spring of this year.
