Low figures relate to the least economical version; high to the most economical. Based on WLTP combined fuel economy for versions of this car made since September 2017 only, and typical current fuel or electricity costs.
Based on "Weighted" mpg; figures depend on the proportion of miles driven in pure electric mode and may vary widely

  • The 520d offers best blend of performance and efficiency
  • Standard cars have plenty of fuel-saving measures as standard
  • Should hold value well, service packages good value

The biggest update to the 5 Series engine range was in July 2020, when mild hybrid technology was fitted to 520i petrol, 520d and 530d diesel engines. Prior to this, the 520d was the only engine to have this technology fitted from late-2019.

With even the high-performance 540i returning 33.6-35.8mpg on the WLTP combined cycle, even the least fuel-efficient 5-series Touring should prove relatively inexpensive to run.

The entry-level 520i petrol engine claims between 38.2-42.2mpg, but we suspect the lack of torque means you'll have to work this engine harder to get it up to speed, making these figures difficult to achieve.

With the 520d returning 49.6-55.4mpg and xDrive all-wheel drive versions claiming 47.9-52.3mpg, owners should easily see well over 40mpg in typical use.

The six-cylinder 530d sees these figures dip to 44.1-47.9mpg.

The plug-in hybrid 530e has a 34 mile electric-only range, which creeps down to 31-32 miles on xDrive models. Combined fuel consumption ranges between 166.2-188.3mpg, which, again, drops to 141.2-156.9mpg for xDrive. You'll have to keep the hybrid battery topped up and cover a lot of short journeys to reach anywhere near these figures.

BMW 5 Series servicing is based on a variable schedule, with the car calculating when a service is required. Expect intervals of around 18,000 miles. BMW offers an affordable fixed-price service package that covers the first three years or 36,000 miles, whichever comes first.

The lowest official emissions rating for the 5 Series saloon comes courtesy of the 530e plug-in hybrid – which claims 35-38g/km thanks to its ability to run on electricity alone for short periods. The xDrive version sees this creep up to 41-45g/km, depending on spec.

Next best is the 520d which claims between 134-149g/km and 141-156g/km for xDrive models. The 530d xDrive emits between 153-167g/km.

All the diesels have an AdBlue tank to help cut down harmful NOx emissions.

For the petrol engines, the 520i ranges from 152-168g/km, while the 540i rises up to 179-192g/km.

Reliability

  • All-new 5 Series Touring is hard to judge
  • High-tech 530e is a bit of an unknown
  • BMW has carried out lots of testing miles

This is an all-new model, so reliability is hard to gauge at time of launch. However, we do know that BMW has carried out 4.7 million miles of testing on this car in an effort to ensure buyers have the best-possible experience.

While most engines here are used in other BMW cars and are the result of years of fettling.  We’ll report back should anything contrary come to light.
