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 342bhp 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 (less than about 12,000 miles or so) may find the 45 TFSI petrol more cost-effective.

Audi Q5 MPG & CO2

The 2.0-litre diesel can manage a respectable 39.2mpg, which is all the more impressive considering it includes quattro four-wheel-drive and a seven-speed automatic gearbox. This figure is for a car fitted with 18-inch alloy wheels, however, the figure drops to 37.2mpg when 19 or when 20-inch wheels are fitted. Depending on wheel choice, CO2 emissions range from 189g/km to 196g/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 33.2mpg on the smallest 18-inch wheels and its 193g/km CO2 emissions place it in the top BiK company car tax category. It's a little 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 14.1kWh battery pack makes the plug-in hybrid Q5 very efficient. According to official figures it can manage up to 113mpg while emitting less than 50g/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 26 miles, which will cover the daily commute for many people. Drive further with a depleted battery and the powertrain will act in a similar way to a hybrid, and the figure will tumble to around 40mpg. Charging from a 7kW home wallbox takes around two hours, increasing to six 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 £470 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.
