Pros	Cons
Exceptionally good to drive, even by BMW's high standards	Controversial looks, in particular the grille
Superb interior quality	Convertible sacrifices some practicality
Brilliant infotainment system	Adaptive suspension costs extra

Quick Summary

The BMW 4 Series (2020-present) is a true stand-alone model that builds upon the 3 Series platform with a lower ride height, wider rear axle, and more direct steering. Available as a Coupe, Convertible, or Gran Coupe, it offers exceptional driving dynamics with a rigid body shell that provides impeccable handling and ride quality. The engine line-up ranges from the efficient 420i with a 2.0-litre turbo petrol to the legendary 3.0-litre straight-six M440i, all paired with a smooth eight-speed automatic gearbox. The Convertible features a fabric roof for minimal wind noise, whilst the Gran Coupe adds rear doors and a hatchback for enhanced practicality with 470 litres of boot space.

The 4 Series excels in refinement, featuring a jewellery-counter interior with soft-touch leather trim, BMW's intuitive iDrive infotainment system, and advanced safety features. The 420d diesel delivers impressive fuel economy of up to 61mpg with excellent real-world efficiency, whilst the 430i and M440i offer more spirited performance. Running costs are manageable with BMW's three-year fixed-price servicing plan at £25 per month, including one free MOT and seasonal health checks. Despite its controversial grille styling, the 4 Series remains a highly desirable and engaging daily driver for those seeking premium performance and luxury.

Best for: Drivers seeking exceptional handling and driving dynamics, those valuing premium interior quality and infotainment, and buyers wanting a stylish coupe or convertible with genuine performance credentials.

Not ideal for: Those prioritising understated styling, buyers seeking maximum practicality without compromising on performance, or those unwilling to invest in optional adaptive suspension for optimal ride quality.
