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 January 2024, the BMW M4 holds a New Car Expert Rating of B, with a score of 69%. 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.

Adult protection: 97%

The BMW M4 Competition shares its safety rating with the mainstream BMW 4 Series Coupe range, which was tested by Euro NCAP back in 2019 and awarded a five-star rating.

The test report offered no significant criticisms, highlighting the maximum scores in the side barrier and more severe side pole test, and the maximum points scored in city-driving tests by the autonomous emergency braking system.

As you might expect, the BMW M4 is not exactly an economical choice, according to data exclusively provided by our commercial partner Clear Vehicle Data.

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

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.
