Fuel economy

Petrol engines 31.0 - 41.5 mpg
Diesel engines 39.8 - 52.3 mpg
Plug-in hybrid petrol engines 117.7 - 139.4 mpg
  • Most frugal engines are the least powerful
  • Petrols set to hold their value best
  • Servicing costs in line with premium rivals

If you want the most fuel efficient model, the D3 reaches between 47.9-52.3mpg. Opt for the manual and this drops down to 44.8-47.1mpg. The D3 diesel is also the cleanest when it comes to CO2 emissions, emitting between 127-130g/km with the manual gearbox. Opt for the automatic and this creeps up to 131-134g/km.

The more powerful and all-wheel drive D4 turbodiesel claims to achieve between 39.8-44.1mpg and emits between 131-135g/km.

The petrol T3 is claimed to achieve between 37.2-41.5mpg with the manual gearbox and 35.8-39.2mpg with the automatic. We managed an indicated 35.2mpg over our time of testing with the automatic gearbox, which is far better than the six-speed manual we initially tried after a day of hard driving, showing a figure below 30mpg.

CO2 emissions for the T3 range between 147-151g/km for the auto and 142-146g/km with the six-speed manual.

Choose the T4 (petrol) and you’ll see this drop down to 33.6-36.7mpg, with CO2 emissions rising to 154-158g/km. If you go for the all-wheel drive version, this drops even further to 32.8-35.3mpg, with CO2 increasing to 161-165g/km.

The petrol T5, meanwhile, manages between 31-34mpg and emits between 164-168g/km of CO2.

In terms of how far it will go for your money, the range breaks down like this in terms of miles per pound.

>> D3: 9.7 - 10.4 mpp

>> D4: 8.0 - 8.9 mpp

>> T3: 7.8 - 8.5 mpp

>> T4: 7.0 - 7.5 mpp

>> T5: 6.6 - 7.3 mpp

Plug-in hybrid slashes CO2 emissions

The T5 Twin Engine XC40 is the one to go for if you want an electric XC40, but don't want to wait until 2021 to get your hands on one. Officially, it has a rating of 141.1mpg, although whether you get close to that or not largely depends on if you remember to plug it in. Its CO2 emissions are 38g/km (meaning it fits into the 12% BIK rate), while it's official rating for electric-driving is 28.6-miles.

A 0-100% charge typically takes around 2.5 hours from a fast charger.

Pure electric

If you're really looking to make a dent on your CO2 emissions, the XC40 Recharge Pure Electric is the way to go, as it's the only XC40 where nothing nasty comes out of an exhaust. It has a 78kWh battery, with a WLTP range of close to 250-miles.

Charging is taken care of via an 11kW AC charger or a 150kW DC fast-charger. Volvo reckons using the latter enables drivers to get an 80% charge in 40 minutes.


  • All-new hardware, but from a trusted maker
  • Hard to predict reliability, early signs positive
  • Mixed results from previous Volvos

The XC40 sits on Volvo’s brand new CMA platform, so making an accurate judgement on reliability is tricky. Of the ‘newer’ Volvos, we only have reliability data on the seven-seat XC90 SUV. Since production began in late 2015 it’s had a number of recalls for engine and minor safety-related issues.

Volvo is currently trying to cement its reputation as a maker of premium cars on a par with Audi, BMW and Mercedes-Benz, so eradicating any reliability concerns will be at the top of its agenda.
