Summary

The BMW M4 Competition is a high-performance coupé and convertible model based on the regular 4 Series range. The current coupé model arrived in the UK in early 2021, with the convertible due to join it before the end of the year.

This is the second generation model to carry the M4 name – the first appeared in 2014 after BMW rebranded its 3 Series coupé and convertible models as the 4 Series. However, the M4 can trace its lineage right back to the original M3 coupé of the mid-1980s.

Here in the UK, we only get the top-spec M4 Competition model, which is powered by a 3.0-litre, twin-turbo, six-cylinder petrol engine that produces 510hp. It is also available with all-wheel drive on the coupé version, while the convertible is rear-wheel drive only.

Reviewers have lavished praise on the M4, though Car magazine dubs it “Munich’s most controversial sports coupe yet,” referring to the styling and particularly the enormous front grilles that dip below the registration plate. Top Gear adds, however, that BMW knows its customers, M4 buyers are “extroverts” and the elongated kidney grilles “don’t actually look too offensive in real life…”

The power impresses widely, but it is about more than rapid acceleration. “The flexibility of the engine is second-to-none, delivering impressive acceleration even in higher gears,” says Parkers.

Equally, testers highlight that the new M4 is not the animal its predecessor was. “The old M4 was a bit feral,” says Auto Express, “but this new version feels more mature and rounded, as if it’s been shipped off to finishing school.”

Evo praises the M4’s rigidity, which means excellent handling; “The precision and response as you turn the wheel is fantastic,” adding that the car builds confidence very quickly.

There are other practical factors, such as rear seats with reasonable space for adults and an adequate boot – but these will feature on the requirements of very few M4 buyers…

As of December 2024, the BMW M4 holds a New Car Expert Rating of B, with a score of 67%. Although it gets fantastic media reviews and has an excellent safety rating, its CO₂ emissions and reliability data are only average, and its running costs are inevitably very high.

Model reviewed: CSL
Score: 9 / 10
“It’s a crazy car with an even crazier price, but in most respects, the BMW M4 CSL justifies its cost by simply being a brilliant driver’s car. One that’s not just faster and more focused than the M4 on which it’s based, but also much more rewarding to drive where it counts. The CSL is an instant legend, if ever there was one, even if its steering remains a touch ordinary.” (Steve Sutcliffe)

“The BMW M4’s design is the obvious talking point, but beneath its dramatic makeover lies a car with a broader breadth of ability than before. It’s easy to live with day to day and now delivers its thundering performance in a more user-friendly and manageable way.”

“The BMW M4 Compeition manages to be both an accomplished all-rounder and a flawed yet brilliantly exciting sports coupe all at the same time. Its everyday on-road manners and luxuriously appointed cabin are almost beyond reproach.”

“This latest M4 is unquestionably the best yet. Though some might reckon it’s not as raw as its predecessor, its greater everyday ability makes it a much better car to live with, while still being comfortable and practical, too.”

Model reviewed: CSL coupé
Score: 8 / 10
“The BMW M4 CSL impresses at times but doesn’t seem to possess the pure magic of recent CS models. The crazy intensity of the M4 GTS is missing, too. Maybe a summer’s day and some sticky Cup 2Rs would help but, for now, the CSL doesn’t seem enough to celebrate the enormity of 50 years of M. Can we have an M2 CSL, please? Or another M4 GTS?” (Jethro Bovingdon)

“If you can get past the BMW M4’s divisive looks – or maybe even begin to like them – everything you’d want in a fast coupe is here. Power, noise, balance, control, grip… and did I mention power? There’s the practicality over a sports car, too.”

Only available with a petrol engine, the M4 is very thirsty and has high emissions. Insurance and servicing costs are also higher than the market average.

If you’re looking at the BMW M4, you might also be interested in these alternatives

Most buyers will consider a BMW M4 for its performance and so potential alternatives are quite varied. Several testers believe the closest rival is also made by BMW, the similarly priced M3 Competition which, being a saloon, is more practical. The likes of the Audi RS 5, Lexus RC F, Mercedes-AMG C63 and Alfa Romeo Giulia Quadrifoglio also come into the reckoning.
