MPG, running costs & CO2 Rating

3.2 out of 5

The type of engine you should choose depends on how deep your pockets are, but in the main the 5 Series GT will be expensive to run. The cheapest model to run is the 520d GT four-cylinder diesel. It offers the best fuel economy and lowest CO2 emissions, but don’t expect blistering performance.

The petrol models feel faster, especially the V8-engined 550i GT, but their fuel economy is so much worse than the diesels’ that you’ll struggle to justify them for real-world motoring.

BMW 5 Series GT MPG & CO2

The diesels are particularly impressive here – even the range-topping 309bhp 535d GT boasts petrol-rivalling performance and 47.9mpg fuel economy. However, if you go for the 520d GT, the economy figure rises to 51.4mpg and CO2 emissions drop to just 144g/km, and you could buy a top-spec supermini with the difference in price compared to the 535d GT. The 5 Series GT has never been a big seller, and although there are few available on the second-hand market, residual values aren’t as high as they are for the standard car.

Buy the 449hp 550i GT and you'll be on first-name terms with your local petrol station attendants – it does little more than 30mpg and its 214g/km CO2 emissions mean a fairly hefty road tax bill of £290 per year. The 306hp 535i GT manages a slightly more respectable 34.4mpg and brings CO2 emissions down to 192g/km for a slightly lower annual tax bill of £265.

Generous standard equipment and reasonably low CO2 emissions make the entry-level 520d GT diesel a tempting choice for company-car users seeking luxurious transport that won't break the bank. Check how much alloy wheel sizes affect particular models, though, as these can alter CO2 emissions slightly, but it can be the difference between one tax band and another.

BMW offers the 5 Series GT with xDrive four-wheel drive in some markets, but it’s not available in the UK. If you do require a four-wheel-drive car in this class, have a look at Audi’s large luxury hatchback, the A7 Sportback. The 3.0-litre TDI quattro costs pretty much the same as the 530d GT, and even though the Audi has two more wheels to power, it’ll go further than the BMW on a tank of fuel.

Insurance

The bottom-of-the-range 5 Series GT sits in group 41 for insurance, while the range-toppers are rated up to group 46. We’d advise you to take some time to sit down and shop around come renewal time, because premiums are going to be stiff for this car.

Warranty

Your BMW 5 Series Gran Turismo is covered for unlimited mileage up to three years and guaranteed against rust for 12 years. Should you find yourself stranded at the side of the road, BMW Emergency Service will come to pick you up and take you to a dealer.

Servicing

All 5 Series GTs benefit from BMW’s fixed-price servicing and extendable warranties, so keeping one on the road shouldn’t cost any more than it would for an equivalent 5 Series saloon or 5 Series Touring estate. There’s not much demand for the GT on the second-hand market, so second hand values aren't as good as they are for the saloon or estate versions of this car.
