AA Cars review

There are few drivers’ cars quite as compelling as the M4, which has a little more edge about it than the M3 and looks utterly sensational. The biggest downside is that it isn’t cheap, especially as BMW now only sells the more costly models in the line-up. If you can stretch to one, you’ll absolutely adore it. It’s sensational to drive.

How much does it cost?

Bought new, the BMW M4 Coupé starts from £93,145 for the M4 Competition xDrive coupé and £97,220 for the Convertible, with the coupé-only M4 CS costing £122,685. On the used market, AA Cars has M4s from around £40,000 upwards for 2020-2021 models with average mileage, but later cars command a lot more – 2023 cars are from about £75,000 upward. Well-specified or lower-mileage examples, particularly with desirable options such as carbon ceramic brakes, special paint finishes or M Carbon bucket seats, can fetch over £80,000. The M4 holds its value well, thanks in part to its strong reputation and limited production of special editions.

Engine and performance

Overview

Under the bonnet is a 3.0-litre twin-turbocharged inline six-cylinder engine, available in several power outputs. The standard M4 produces 480bhp and 550 Nm of torque, accelerating from 0 to 62 mph in 4.2 seconds with a manual gearbox and rear-wheel drive. The M4 Competition increases that power output to 510 bhp and 650 Nm, sprinting from 0 to 62 mph in 3.9 seconds with an eight-speed M Steptronic automatic transmission, available in both rear-wheel drive and xDrive all-wheel drive configurations. In M4 Competition xDrive form, the only one offered from 2023, it gets from 0-62mph in 3,5 seconds thanks to the extra traction.

At the top of the range, the M4 CS/CSL delivers 550 bhp and 650 Nm, sprinting from 0 to 62 mph in just 3.7 seconds, exclusively with the eight-speed automatic gearbox and rear-wheel drive. Performance highlights include an Active M Differential, adaptive M suspension, configurable M drive modes, and powerful M Compound brakes, with optional carbon ceramic discs for even greater stopping power.

BMW M4 performance

Out on the road

The BMW M4 is a car with an astonishing breadth of abilities, remaining perfectly usable around town yet turning into a truly enthralling driver’s car when pushed. It sounds fantastic, too, thanks to its M tuned exhaust system. It’s surprisingly easy to live with. Steering is precise and well-weighted, and those with the M Steptronic gearbox can be entirely docile around town despite their incredible performance. The Competition and CSL variants dial up the excitement, with sharper throttle response, firmer suspension, and a more aggressive character – but even these models can settle into everyday driving when required. For those who value all-weather usability, the xDrive models provide excellent grip and stability, as well as better traction off the mark.

Ride and handling

Under the skin, the M4 is a very sophisticated car, with a clever five-link rear axle, a double-joint sprung front axle and trick adaptive dampers. None of these are exploited when in Comfort Mode, but even then, the M4 is an engaging car to drive. Switch into Sport or Sport Plus and you’ll lose what’s actually a surprisingly supple ride, but in exchange you’ll get astonishing levels of grip and composure at the limit – it really is a terrific car to blast along in on twisty roads, and while it doesn’t feel as overtly sporting as the Coupé, the Convertible doesn’t lag behind in terms of its ability.

The M4’s overall balance is superb, with rear-wheel-drive models offering playful dynamics for keen drivers, while the xDrive system in Competition models ensures maximum traction and minimal drama, allied to sensational steering feel and feedback on all models. The CS and CSL take things even further, with a bespoke suspension tune, lighter components, and track-focused tyres, delivering razor-sharp responses and a truly immersive driving experience – but it’s also a pretty hardcore machine, best-suited to track use. Unless you’re a track junkie or a collector, as less edgy M4 is arguably a better car Interior and Features

Interior and features

Interiors

All versions of the M4 are civilised, but there are still clear motorsport influences throughout. You’ll find a mix of materials, from premium Merino leather upholstery, to lightweight carbon fibre trim. The dashboard features BMW’s latest curved display, integrating a 12.3-inch digital instrument panel and a 14.9-inch central touchscreen running BMW Operating System 8, with a head-up display. Front occupants are treated to supportive M Sport seats (with optional M Carbon buckets for even greater lateral support and less weight). The driving position is low and purposeful, while the thick-rimmed M steering wheel feels perfectly chunky in the hands. Rear seat space is adequate at best, and taller passengers may find legroom limited.

Boot space and practicality

While the M4 is first and foremost a performance coupé, it remains practical enough for daily use. The boot offers 440 litres of space in the Coupé, easily accommodating a pair of suitcases or golf bags, while the Convertible provides 370 litres with the roof up. With the rear seats split-folding in a 40:20:40 configuration, the M4 offers increased flexibility for carrying larger or bulkier items. Cabin storage is thoughtful, with cupholders, large door pockets, and additional cubbies for personal items. While rear seat access is naturally more restricted than in a saloon, the wide-opening doors and front seats that slide forward make entry relatively straightforward.

Features

As you’d expect for the premium pricing, the M4 is generously equipped as standard. Notable features include BMW Live Cockpit Professional, which comprises a 12.3-inch digital dashboard and a 14.9-inch touchscreen, along with wireless Apple CarPlay and Android Auto for seamless smartphone integration. The Harman Kardon surround sound system ensures high-quality audio, while wireless phone charging adds everyday convenience. For added usability, gesture control and a voice assistant are provided, and Competition models benefit from a head-up display. The car also features physical climate controls for straightforward operation and an extensive suite of driver assistance technologies. Most functions are operated via a rotary iDrive controller.

Trim and colour options

The BMW M4 is offered in three trim levels. The standard M4 (2020-23) comes with rear-wheel drive, a manual gearbox, Merino leather upholstery, M Sport seats, and adaptive suspension. The M4 Competition features an automatic gearbox, optional xDrive for all-wheel drive capability (standard from 2023), a Harman Kardon audio system, and a head-up display. For those seeking a more track-focused experience, the M4 CSL (later CS) is lighter and more powerful, equipped with unique carbon fibre seats, exclusive paint and trim, and produced in limited numbers.

There is a broad selection of exterior colours, ranging from classic Alpine White and Black Sapphire to vibrant Sao Paulo Yellow, Toronto Red, Isle of Man Green, and various Frozen metallic finishes. Interior trims offer extended or full Merino leather in shades such as Black, Silverstone, Kyalami Orange, and Yas Marina Blue/Black, complemented by optional carbon or aluminium accent finishes. In addition, the BMW Individual programme gives buyers the opportunity for further personalisation, including bespoke paintwork, unique interior materials, and special trim finishes.

Safety and reliability

The BMW M4 is based on the latest 4 Series platform, which has performed well in Euro NCAP testing, though the M4 itself has not been specifically crash tested. Standard safety equipment includes multiple airbags, autonomous emergency braking, lane departure warning, blind-spot monitoring, rear cross-traffic alert, and adaptive cruise control. BMW’s Active Protection and Driving Assistant Professional packages provide additional features such as traffic sign recognition, steering and lane control assist, and evasive manoeuvre support. Reliability has been strong so far, while BMW offers a comprehensive three-year, unlimited mileage warranty, with extended warranties and service packages also available.

MPG, emissions and tax

Fuel economy isn’t the M4’s strong suit, but nor would you expect it to be from a car that’s openly all about performance. Official WLTP figures range from 28.0 to 29.1 mpg for the Coupé, and slightly less for the Convertible. CO₂ emissions fall between 223 and 231 g/km. Road tax (VED) is £620 a year for the first five years as the M4 is subject to the Luxury Car VED Supplement, and £195 a year thereafter. Insurance groups are high, reflecting the car’s performance and value, typically falling between groups 42 and 50.
