MPG, running costs & CO2 Rating

4.0 out of 5

With only three engines and two plug-in hybrid versions to choose from, it’s fairly easy to get a handle on the Vauxhall Grandland X’s economy credentials.

Vauxhall Grandland X MPG & CO2

The 1.2-litre turbocharged petrol engine officially returns 42.2-45.6mpg when combined with the six-speed manual gearbox, and is claimed to manage 40.4-42.8mpg if you choose the automatic. If you cover more than around 12,000 miles a year or plan on using your Grandland X to tow, you’ll probably want the 1.5-litre or 2.0-litre diesel engines. The 1.5-litre officially returns 48.7-54.3mpg, though the optional eight-speed automatic gearbox brings a small increase in running costs.

Offered a Grandland X as a company car? You’ll be liable for about average Benefit-in-Kind (BiK) rates for a petrol model (although it’s worth noting that the manual slips into a band above the automatic gearbox) while the 1.5-litre diesel with either gearbox makes you liable for a slightly higher BiK rate. The 2.0-litre diesel, meanwhile, occupies a high BiK band.

The Hybrid and Hybrid4 offer company-car drivers significantly lower BiK payments thanks to CO2 emissions of 34 and 35g/km respectively. Owners may also be able to save some fuel but this will depend how far they drive because the 13.2kWh battery pack can officially get the car and its occupants 35 miles without the petrol engine - a figure we struggled to manage during our first test drive.

If your daily commute is 30 miles or less, and you can top-up every night, fuel economy will soar, but after our extended drive the Hybrid4 averaged 45mpg. Charging the battery pack can be accomplished with a three-pin plug, but Vauxhall, rather stingily, charges £500 extra for the hardware needed for faster, 7kW home charging, which sees the battery filled in a couple of hours.

All Grandland Xs cost £150 a year in road tax (£140 for the Hybrid4) but for models that cost above £40,000 (including options and before discounts) you’ll be required to pay an extra £325 a year for the first five times you renew the tax.

Insurance groups

Unlike many models, the entry-level trim is the most expensive to insure, sitting in group 15 if you choose the petrol and 18 with a diesel engine. Business Edition Nav lowers insurance groups thanks to its added autonomous emergency braking, dropping the petrol to group 14 - although the 2.0-litre diesel is in group 22 and the hybrid versions are in groups 27-30. These are slightly lower ratings than the Nissan Qashqai, which sits in group 17 with an entry-level petrol engine.


Vauxhall’s three-year/60,000-mile warranty is standard for the industry – nothing more, nothing less. This matches the Qashqai and Skoda Karoq, but the Hyundai Tucson gets a five-year/unlimited-mileage warranty, while the Kia Sportage comes with a seven-year/100,000-mile warranty as standard.


Better news here: Vauxhall’s service plans are reasonably priced and will make budgeting for maintenance easy. Costing around £20 per month, Vauxhall Care looks after the first three services, three years of roadside assistance and the cost of the first MOT.
