Aston Martin DBX review - MPG, CO2 and running costs

You’ll need deep pockets if you’re going to run a super-SUV like the Aston Martin DBX.

MPG, CO2 and running costs Rating

2.5 out of 5

  • Pace
  • Sports car handling
  • SUV practicality
  • Build quality not class-leading
  • Polarising looks
  • Dated infotainment

The DBX has a list price of around £160,000, but as with its Lamborghini Urus rival that’s just the start, there’s an array of accessory packs, optional equipment and Aston Martin’s Q Division on hand to perfectly personalise your DBX. Buyers should expect that even with just a few choice options ticked, the price could easily reach nearer £200,000.

The mounting cost of DBX ownership continues when you factor in that the claimed fuel economy is just 19.73mpg on the combined cycle - although anyone choosing to exploit the power on offer from the two-tonne SUV, will probably see this fall to near single figures. Still, with a light right foot you might be able to eke out around 370 miles from the 85-litre tank. Emissions are unsurprisingly high at 269g/km, so don’t expect to beat any city congestion charges when driving a DBX. 

You’ll also need to think about the premium servicing costs involved in running a bespoke, British-built, luxury 4x4, and the expensive consumables like tyres and brake pads. All of which will need regular attention if you intend to drive the DBX to its full potential.

Insurance groups

There’s a definite theme to the ownership of an Aston Martin DBX - it’s expensive. The SUV sits in the highest group 50 for insurance, as do all of its rivals, so expect costly insurance premiums. 

Depreciation

Residual value data isn’t yet available for the DBX, but there’s nothing to suggest it won’t perform reasonably strongly on the used market. However, Aston super-SUV ownership starts with a high list price and encourages you to add expensive options, so you’ll still probably be looking at a hefty chunk of money lost - particularly as the manufacturer is aiming to produce the DBX in greater volume than its supercar siblings.
