Rating: 65.0

Summary

The BMW 4 Series Gran Coupé is a five-door version of the 4 Series Coupé, which is, in turn, based on the BMW 3 Series saloon.

The range of engines available for the Gran Coupé is identical to the 4 Series Coupé and Convertible, with customers able to choose between turbocharged petrol and diesel units. All models are fitted with an eight-speed automatic gearbox, while all-wheel drive is available on selected models.

Attempting to offer the practicality of a family car while providing the styling and performance of a sporty coupé, many UK reviewers commend the 4 Series Gran Coupé for its easy-to-load hatchback tailgate instead of a saloon bootlid, while Car Keys also praises the car for its high-quality interior and “engaging and involving” driving dynamics.

If you need four doors but the idea of a regular 3 Series saloon is not especially appealing, the 4 Series Gran Coupé could be an appealing option. Not all agree that the Gran Coupé offers the best of both worlds, however. “Foot room is good”, Company Car Today says, “but anyone approaching or over six feet tall will struggle for headroom in the back thanks to the lower roofline.”

In concluding its review, Carwow explains that the BMW 4 Series Gran Coupé doesn’t match the practicality of the BMW 3 Series, and isn’t as “sleek” as the 4 Series Coupé. Therefore, you may be better off with one or the other, particularly if practicality is more important to you, as the 4 Series Gran Coupé costs almost £8,000 more than the entry-level 3 Series saloon.

As of December 2024, the BMW 4 Series Coupé holds an Expert Rating of B, with a score of 65% in both new and used car calculations. It has an excellent safety score and low CO₂ emissions, although running costs are high.

“While it’s undoubtedly an indulgent purchase it’s also one you can make with your heart and head in agreement, given it can play modern, connected commuter Monday to Friday, sensible family car at the weekends and – should opportunity arise – act like a proper sporting coupe as well.”

“Although its star attraction is its dynamics, the 4 Series Gran Coupe scores for being such a good all-rounder and making you feel great about driving it, it quietly gets on with dealing with the day-to-day stuff impressively well.”

Car Keys+

Score: 10 / 10
“The BMW 4 Series Gran Coupe is a truly excellent model. Combining sportiness with everyday usability, it’s undoubtedly the pick of the 4 Series line-up. Though the styling won’t suit all, if you can live with the looks, it’s without question the leader of this class due to its sheer breadth of talents.”

Safety rating

Independent crash test and safety ratings from Euro NCAP

No safety rating

As of December 2024, the BMW 4 Series Gran Coupé has not been assessed by Euro NCAP.

This is something of a surprise since both the coupé and convertible versions of the 4 Series have been tested (both scoring a top five-star rating), along with the electric i4 – essentially an EV version of the fossil-fuel Gran Coupé – which scores four stars. The 3 Series saloon, which the 4 Series is based on, has also been assessed and holds a five-star rating.

Because there are structural differences between the 3 Series and various 4 Series models, and because the electric i4’s electric motor and battery may perform differently in an accident to a conventional engine/gearbox and fuel system, we can’t assume that the 4 Series Gran Coupé would have a similar score to any other models.

Reliability score

All data based on MotorEasy average workshop costs for extended car warranty claims

The BMW 4 Series family has an average reputation for reliability, according to workshop and warranty data provided exclusively to The Car Expert by our partners at MotorEasy. This score covers all versions of the current-generation 4 Series (Convertible, Coupé and Gran Coupé) as well as the original (pre-2020) models.

The average repair bill to date has been just under £850, which is obviously a lot more than a used car warranty – so bear that in mind if you already own a BMW 4 Series or are looking at buying a used 4 Series.

The most common faults with 4 Series models to date have been engine-related. These are also the most expensive to repair, with an average bill of £2,000. Gearbox repairs are even more expensive, averaging more than £2,600, but are thankfully not as common. Other faults – like suspension, fuel system, electrics and brakes – have much lower repair bills.

Running costs for the BMW 4 Series Gran Coupé are a bit of a mixed bag, according to numbers provided exclusively to The Car Expert by our data partner, Clear Vehicle Data.

Petrol models offer a below-par fuel consumption of 40 mpg on average, while diesel models are much more efficient, offering 55 mpg. Insurance is neither expensive nor cheap, and service and maintenance costs are fairly average, too, when compared to the rest of the market.
