Rolls-Royce Cullinan SUV - MPG, running costs & CO2

Everything about the Rolls-Royce Cullinan is big, including its running costs

MPG, running costs & CO2 Rating

1.5 out of 5

We think it's probably fair to say that fuel-efficiency and emissions weren't top of the list when Rolls-Royce signed off on its 6.75-litre twin-turbo V12. In many ways it's one of the world's great engines, but it's probably best not to mention its running costs to your bank manager.

Rolls-Royce Cullinan MPG & CO2

With a petrol engine that has three times the capacity and triple the number of cylinders as most family cars, pulling an SUV weighing 2.7 tonnes, an 18.8mpg average fuel-economy figure perhaps isn't surprising. But there's no getting away from the fact it makes the Cullinan one of the thirstiest models on sale, even putting the barmy Lamborghini Urus supercar-style SUV in the shade.

CO2 emissions of 341g/km stick with the 'three' theme, being around three times the amount of a humble lifestyle SUV. Still, road tax costs just £140 a year, with a £310 surcharge in years two to six owing to the Cullinan's lofty price tag.

Insurance groups

The expense, complexity and rarity of the Cullinan means it's almost certain to be placed in group 50, the top insurance bracket.

Warranty

Every Rolls-Royce comes with a four-year/unlimited-mileage 'ownership package' that goes well beyond the realms of a normal warranty. Servicing, repairs, maintenance and roadside assistance are all included, so you'll only need to fork out for consumables like tyres and any replacement glass if it gets chipped or cracked.

Servicing

Servicing for the first four years is taken care of by the package described above, with numerous sensors around the car checking components like the engine oil, brake pads and filters and sending data back to the dealership. When a service is required, the necessary maintenance can be tailored to the individual Cullinan.
