If you want the most fuel efficient model, the Recharge plug-in hybrid is the one to go for. It's available in two different power outputs, but the fuel consumption figures and CO2 emissions remain the same for both. Officially, they have a rating of 134.5mpg, although whether you get close to that or not largely depends on if you remember to plug it in. CO2 emissions are 48g/km.

A  zero to 100% charge typically takes around 2.5 hours from a fast charger.

The cheapest engine is the T2. It claims between 37.2-40.4mpg and is only available with a manual gearbox. Emissions are 158-173g/km.

The T3 is claimed to achieve exactly the same mpg as the T2 with the manual gearbox and 35.8-38.7mpg 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 T2 and T3 range between 158-173g/km and 158-179g/km respectively.

Choose the B4 hybrid and the figures range from 34.0-39.2mpg depending on whether you pick front or four-wheel drive. Emissions range from 162-186g/km. The B5 hybrid is very similar. It scores 34.4-36.7mpg and 174-186g/km.

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.

Diesel no longer available

Diesels are no longer available from new. But if you're looking at XC40s on the used market, the D3 reaches between 47.9-52.3mpg. Opt for the manual and this drops down to 44.8-47.1mpg. The D3 is also the cleanest diesel 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.

>> D3: 9.7 - 10.4 mpp

>> D4: 8.0 - 8.9 mpp

Reliability

  • 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. 

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.

Saying that, in its lifetime, it has been subject to three safety recalls. Two were regarding software issues - one related to the automatic emergency braking system, the other relativing to the car's connectivity module. While there was also recall regarding rear seat back locks.
