By 2017, the first generation version of BMW’s 4 Series Coupe was facing newer rivals in the mid-sized sports coupe segment but it was up for the fight, especially in this usefully revised facelifted guise. The rear-driven handling dynamics remained class-leading and were usefully improved as part of the car’s mid-term update. Plus they were matched to extra technology and a more powerful road presence. Potentially, this is everything you’d want in a car of this kind from this era.

The History

Launched in 2013, the 4 Series Coupe, in contrast to its 3 Series Coupe predecessor, was intended to be far more of a stand-alone model. Even though under the skin, it still shared pretty much everything that made its less stylish but more practical showroom stablemate, the ‘F30’ generation 3 Series saloon, such a brilliant car. BMW launched this model to better target the threat posed by Coupe versions of Audi’s A5 and Mercedes’ C-Class. A Convertible version was launched in 2014 and a five-door Gran Coupe 4 Series model followed a year later. BMW upgraded the petrol engine line-up in 2016, then facelifted the range in the Spring of 2017. It’s the post-20217 facelift Coupe model we’re going to look at here as a used car buy.

This is the sort of car BMW has always done very well, a mid-sized rear-driven performance-orientated coupe with perfect weight distribution and a purposeful demeanour. It all made plenty of sense when the Munich maker first launched this 4 Series Coupe model back in 2013 – which meant that this improved facelifted version was even more appealing.

This was the car that replaced several generations of BMW’s 3 Series Coupe and subsequently appeared in two other bodystyles – a Convertible and a stylised five-door hatch, the 4 Series Gran Coupe. Both these variants shared the changes made in mid-2017 to this two-door version, updates needed to keep this car competitive in the face of tougher competition from direct Mercedes and Audi rivals.

These two competing brands had really upped their game in the mid-sized executive coupe segment by 2017, Mercedes launching a second generation C-Class Coupe in 2015 and Audi following up with a MK2 model version of its A5 Coupe a year later. In response, this 4 Series got revised styling, an upgraded cabin, extra technology and an improved specification. Perhaps more significantly, there were dynamic changes too – a much more responsive steering system and a revamped suspension set-up that was said to enhance this car’s handling capability without damaging its ride comfort. In this form, this car sold until mid-2020 when a second generation model was launched.

What You Get

This two-door 4 Series has all the predictable BMW coupe design elements we’ve seen so often over the years – the short overhangs, the long bonnet, the set-back passenger compartment, the shallow frameless side windows leading into the signature Hofmeister kink on each C-pillar and a flowing roofline that offers up a low, stretched silhouette. It’s a true sportscar profile that’s here been… re-interpreted a little.

Inside, as with obvious rivals, you’re treated to one of those ‘belt butlers’, an electrically-extending arm that (rather slowly) hands you your belt buckle once you get in. The driving position’s lower-set than it would be in the kind of more ordinary 3 Series model that shares most of its engineering with this car. And you get a re-designed leather-wrapped sports steering wheel that feels great to hold.

Getting into the back isn't the easiest task in the world and once you're snuggled in there, you'll find a slightly strange combination of decent legroom but rather pinched headroom. There’ll be reasonable room for their luggage too. Once open, the boot reveals a large but shallow 445-litre space that probably does quite well to get within a whisker of the cargo capacity of slightly frumpier-looking rivals. BMW insisted on charging extra for a split-folding rear bench from new, but most original buyers specified that.

What To Look For

Most of the 4 Series Coupe buyers in our ownership survey were very happy with their cars but inevitably, there were a few that had issues. One owner had to replace a catalytic converter, an exhaust pipe and an auxiliary radiator, while on another, the air tube on the turbo broke. Elsewhere in our survey, there were problems with water pump thermostats and rear indicator bulbs. On one car, the front camera tended to fail in high climate temperatures or when sunlight directly shone on it. Niggly problems included a failure of the trunk release, the remote entry system and the front passenger’s electric seat. There are also issues with the surfaces of the alloy wheels pitting: check the rims carefully on the car you’re looking at.

On The Road

This 4 Series Coupe built on a familiar basic winning Bavarian formula. Rivals have tried to copy the front engine, rear wheel drive BMW layout with its near perfect 50:50 weight distribution – but never quite managed to deliver a package with the same kind of involving finesse. The suspension was revised as part of the 2017 update, the standard passive set-up as a result being firmer than before. That slightly increased take-up of the ‘Adaptive M Sport Suspension’ variable damping set-up we’d recommend. As with the original version of this car, a ‘Drive Performance Control’ system tweaks response from the throttle, the steering and the optional 8-speed auto gearbox to suit the way you want to drive.

Engine-wise, most buyers choose one of the base 2.0-litre variants, either the 184bhp 420i petrol model or the 190bhp 420d diesel, a variant capable of up to 62.8mpg and 119g/km of CO2 in manual guise (NEDC figures). From new, both derivatives could be ordered with xDrive 4WD as an option. Need more power? Diesel folk are offered two six cylinder auto-only variants, the 258bhp 430d and the 313bhp 435d. Petrol people get a 2.0-litre 430i model tuned up to 252bhp and two six cylinder options, the 326bhp 440i and the 431bhp M4.


If you’re looking for a mid-sized premium badged executive sports coupe from the 2017 to 2020 period, this BMW 4 Series Coupe is still the car in this class that does it all, the sector benchmark, the go-to choice in its segment. This car, BMW reckoned, was more than just a ‘love letter to performance’. Instead, it offered something deeper than that: the promise of a passionate affair. It still does.
