Low figures relate to the least economical version; high to the most economical. Based on WLTP combined fuel economy for versions of this car made since September 2017 only, and typical current fuel or electricity costs.
Based on "Weighted" mpg; figures depend on the proportion of miles driven in pure electric mode and may vary widely

Fuel economy

Petrol engines 37.2 - 45.6 mpg
Diesel engines 42.8 - 54.3 mpg
Plug-in hybrid petrol engines 192.0 - 225.0 mpg
  • Good diesel efficiency
  • Tempting petrol, too
  • Hybrids are pretty quick

Efficiency kings of the Grandland X range are the hybrids. The Hybrid4 is officially capable of 204mpg, with CO2 emissions of 34g/km. The cheaper Hybrid model (with only one electric motor rather than two) is not far off its more expensive cousin. The MPG rating stands tall at 192mpg, and CO2 emissions of 35g/km.

If you regularly cover a lot of miles, the diesel could be the one to go for. The 1.5-litre Turbo D diesel promises up to 68.9mpg in both manual and automatic gearbox guises. As these diesels are RDE2 Compliant, company car drivers don't need to pay the 4% surcharge on BIK tax, which can reduce monthly payments by between £17 and £34 per month for a standard-rate tax payer.

Finally the petrol option, a 1.2-litre turbocharged unit, is only slightly behind with up to 54.3mpg officially claimed, again in manual and automatic specifications. Efficiency hasn't been a Vauxhall strong point in recent years, but the Grandland X benefits from (relatively) squeaky clean Peugeot engines putting out as little as 108g/km in the case of the 1.5-litre Turbo D models.

Is it reliable?

  • Built alongside the Peugeot 3008
  • Engines and platform shared too
  • Makes its reliability a bit hard to call

It’s hard to comment on this Vauxhall’s reliability because it's built in partnership with Peugeot, in this case sharing components with the 3008

If we had to take a punt, we’d say the French car firm doesn’t have an exactly sparkling history of reliability, but the engines used in the Grandland X are of a new generation with the promise of better dependability. The hybrid engines are new to Vauxhall too, so it's too early to comment on their reliability.

The materials used inside the car on the whole feel quite robust, although there are some notably thin plastics lower down, particularly on the doors.
