Cupra Formentor review - MPG, CO2 and running costs

A wide range of engines means the Cupra Formentor doesn’t have to be expensive to run

Overall Auto Express Rating

3.8 out of 5

Past Cupras have offered one powerful petrol engine, because they sat at the top of the range and were the fastest models available. Now, the engine range is much wider, and electrified options have been added as Cupra kicks off its transition to an electric-only brand. As such, the Cupra lettering on the bootlid no longer has to mean that the car is costly to run.

Picking the 306bhp petrol engine will bring fairly chunky running costs, however. This is a classic high-performance petrol, with four-wheel drive and an automatic gearbox, and up to 33.2mpg is the predictable outcome - although be prepared for your consumption readout to drop into the teens with fast driving. That’s pretty similar to its main rivals, so par for the course if you’re looking at a petrol SUV with this much power. 

The two other 2.0-litre petrol engines both return 37mpg, while the entry-level TSI 150 engine offers very acceptable efficiency. It returns 44.8mpg and 143g/km of CO2, which means it’ll be affordable to run for private buyers and out of the top Benefit-in-Kind (BiK) tax band for company-car drivers.

All the other petrol engines occupy the highest 37% BiK bracket, but business users will be far better off with either of the plug-in hybrids. The addition of an electric motor sees economy rise to 188mpg or 235mpg, while CO2 emissions of 27-33g/km means that BiK liability will be around a third as much as the petrol versions.

The plug-in hybrids may also appeal to private buyers - especially if you live in a town or city and want an element of zero-emission driving. Up to 34 miles is possible on a charge, and topping back up takes around four hours from a home wallbox.

Insurance groups

Insurance shouldn’t be too expensive for the Cupra Formentor, with the 148bhp engine slotting into group 19 out of 50. Other V1 and V2 models occupy groups 24-25, while even the more powerful plug-in hybrid VZ versions sit in group 26. Unsurprisingly, the highest group belongs to the 306bhp petrol (group 33), but that’s a lot lower than the BMW X2 M35i (group 42).

Depreciation

Our data suggests that the Formentor will retain between 53.5% and 56% of its value after three years/36,000 miles, with V1 and V2 versions performing ever-so-slightly better than the VZ versions. That’s similar to the Cupra Ateca (54%) and Volvo XC40 (55%), and a little better than the Mercedes GLA, which is forecast to retain 50% of its original value.
