  • Not cheap to service or maintain – like all Audis
  • V6 diesels will offer lowest running costs
  • SQ7 TDI costs most to run, but retains more value too

Running cost figures for the updated Q7 range in 2019 is yet to be confirmed. However, Audi claims the new 48-volt mild-hybrid system will improve efficiency, so expect figures to be better for each model, even though they're tested under the newer WLTP system that's designed to better reflect real-world driving.

For the pre-facelift Q7 range, the lower-power 3.0-litre TDI diesel with 218hp makes the most sense. For a start it’ll achieve around 5mpg more than its higher-powered brother, with a claimed combined economy figure of 52.3mpg. The slightly lower CO2 emissions (144g/km versus 153g/km) will reduce annual VED car tax for private owners too.

And thanks to 19-inch alloy wheels, rather than the larger 20-inch items on the S Line, when it comes to replacing the tyres it’ll work out fractionally cheaper too.

Audi Q7 E-Tron and SQ7 TDI running costs

The Q7 E-Tron plug-in hybrid deserves a mention here. Its claimed fuel economy of 156mpg is entirely unrealistic for most users, but if you only do short journeys then it could work out that you use hardly any diesel at all. The 48g/km CO2 output (dependent on wheel size) also makes it the only Q7 that a company car tax payer could realistically use.

As you may expect, use the SQ7’s mighty TDI diesel engine much and you’ll see fuel economy drop to near-supercar levels. Audi’s servicing and maintenance is also known to be reassuringly expensive, but you can expect a quality experience to go along with the cost.

Depreciation is strong across the range, but it’s the SQ7 that performs best in this respect, retaining 62% of its value after three years and 60,000 miles. All Q7s retain better than 50%, however. 

Green credentials

As with fuel economy figures, CO2 emissions are yet to be confirmed for the updated Q7 range.

With the Predictive Efficiency Assist, available as part of the Tour Pack as well as an individual option, the Q7 can adjust its gear ratio choice, throttle application and other parameters based on topography and other mapping data, including live traffic information. It’ll also suggest alternative routes that will be more economical and efficient than the one you’re currently on, even if you’re not actually using the sat-nav to find your destination.

The lowest-possible emissions are 48g/km, achieved by the E-Tron Q7 on its smallest wheels. This means tax breaks for private and company car drivers.

Reliability

  • Common Audi parts should be reliable
  • Some newer tech has been patchy
  • Four recalls but cars will have been fixed

The Audi Q7 uses a lot of parts that are tried and tested in other Audi products, so reliability in that respect should be good. However, we’ve heard of electrical issues with Audi’s Virtual Cockpit system in the early days. However, it’s now been updated to a revised system, and we’re yet to come across any issues with it.

The 48-volt electrical system in the E-Tron caused Audi to take it off sale for a short period after launch to rectify, but this newer system has been implemented in the A6, A7 and A8 since then, and is much more reliable.

There have also been four official DVSA recalls, but all cars should have had these faults fixed.
