BMW 5 Series Touring estate (2010-2017) - MPG, running costs & CO2

The BMW 5 Series Touring employs a range of measures to lower fuel consumption and keep CO2 emissions down. These include active radiator grilles that open or close to balance engine temperature and aerodynamic efficiency, a system that switches off the engine at traffic lights and brake-energy recuperation.

The diesel model range starts off with the 2.0-litre 518d, which returns an average of 60.1mpg and emits 122g/km of CO2, all of which makes it an extremely attractive company car. However, we’d recommend the 520d, which uses a slightly retuned version of the same engine. It has more horsepower and therefore better performance, but can return an average of 61.4mpg and emits the same 122g/km of CO2.

However, if you have deeper pockets and a desire to go quickly, you could always go for the 535d model, which returns an average of 49.6mpg and emits 149g/km of CO2, but can get to 62mph from rest in just 5.4 seconds.

It stacks up pretty well as a private buy, too, because it’ll hang on to at least 46% of its initial value over a three-year ownership period. If you're basing your purchase largely on the car's CO2 emissions, check for any differences between models, because the size of the wheels can have an impact and alter the emissions.

BMW 5 Series Touring MPG & CO2

The standout version – both as a company car and a private buy – is the BMW 520d Touring. It emits just 122g/km of CO2, so sits in a low company-car tax band. Private buyers and company-car users alike will also like the average fuel economy figure of 61.4mpg.

There’s also a 3.0-litre diesel model that has the performance of a sports car, but which can also return almost 50mpg and emits 149g/km of CO2. And some of the petrol versions are worth looking at, too. The 528i Touring is powered by a 2.0-litre turbocharged engine that produces 242bhp while managing average fuel economy of 44.1mpg. Its CO2 emissions of 149g/km aren’t quite as impressive, though.

If that isn’t pokey enough for you, there’s always the full-fat 535i Touring, which has a turbocharged 3.0-litre engine up front. Just be sure you really want to hear the sound of a six-cylinder engine, because average economy of 36.7mpg and CO2 emissions of 179g/km mean you’ll certainly be paying heavily for it.

Insurance

The bottom-of-the-range cars sit in or around group 41 for insurance, and the range-toppers are up around group 46. We’d advise that come renewal time, you take some time to sit down and shop around, because the premiums are going to be stiff.

Warranty

Your BMW 5 Series Touring will be covered for unlimited mileage up to three years and is 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

No BMW 5 Series Touring is going to be cheap to run, but the provision of a number of fixed-price servicing plans should at least take the sting out of your annual maintenance costs.
