MPG, running costs & CO2 Rating

4.5 out of 5

Two engines are offered in the latest Audi Q5, with a more powerful choice, the Audi SQ5, now fitted with a 336bhp diesel engine. Those who make frequent long journeys are likely to find the 40 TDI diesel most suitable, while drivers who cover a low annual mileage or want a sportier SUV may find the 45 TFSI petrol more suitable. Unusually, the 40 TDI is a little cheaper than the 45 TFSI, so it makes the most sense to cost-conscious buyers.

Audi Q5 MPG & CO2

The 2.0-litre diesel can manage a respectable 44.8mpg at best, which is all the more impressive considering the Q5’s standard spec includes quattro four-wheel-drive and a seven-speed automatic gearbox. This figure is for a car fitted with 18-inch alloy wheels, however, and the figure drops slightly when 19 to  21-inch wheels are fitted. Depending on wheel choice, CO2 emissions range from 165g/km to 180g/km of CO2, which means the diesel Q5 falls into the highest Benefit-in-Kind (BiK) company-car tax band.

The 2.0-litre petrol engine returns around 32mpg and its 193g/km CO2 emissions place it in the top BiK company car tax category. It's quite a bit faster than the diesel, though, and running costs are similar to the even quicker and more expensive SQ5.

The combination of a 2.0-litre petrol engine, electric motor and a relatively large battery makes both the plug-in hybrid Q5s potentially very efficient. According to official figures the 50 TFSI e can manage up to 188mpg while both it and the 55 TFSI e emit less than 40g/km of CO2, slashing the cost of Benefit-in-Kind taxation for company-car drivers and allowing free access to most low-emissions zones including the London Congestion Charge zone.

Of course, just like all PHEVs, the actual fuel economy figure you manage will depend on how much of the time the car is running on electricity and how much the petrol engine is required. From a full charge, the plug-in hybrid Q5 models can travel on electricity for up to 39 miles, which will cover the daily commute for many people.

However, with an impressive amount of performance on tap it’s likely many TFSI e drivers will be tempted to use up the battery reserves without worrying too much about efficiency. In that case, you can expect a significantly lower electric-only range and to use more petrol because driving with a depleted battery could see the fuel efficiency figure tumble to less than 40mpg. Charging from a 7kW home wallbox takes around 2.5 hours, increasing to seven for a three-pin plug.

The Audi Q5 starts from just over £40,000, so a £325 surcharge is payable the first five times your road fund license is up for renewal – this £475 annual bill drops to £150 from the sixth year onwards, with a £10 discount for the plug-in hybrid.

Insurance groups

The 2.0-litre diesel Q5 sits in insurance group 31 out of 50, while the 2.0-litre petrol is more costly to insure, in group 35.

Warranty

One thing that doesn’t look set to change any time soon is Audi’s slightly measly warranty. While BMW and Mercedes provide a three-year/unlimited-mileage guarantee with all their cars, Audi makes you settle for the same three years, but with the unwelcome addition of a 60,000-mile cap in that time.

Servicing

Maintaining the new Q5 shouldn’t be eye-wateringly expensive, and Audi’s fixed-price servicing offers (which start at around £160) are reasonably priced. Expect tyres for those big SUV wheels to be pretty expensive, though.
