  • All engines will be thirsty, including diesels
  • P400e plug-in has best fuel economy claims
  • You’ll need deep pockets to run a Sport

You don’t go into Range Rover Sport ownership expecting low running costs and high fuel economy claims, so it’s no surprise that – pretty much across the board – the Sport will be an expensive car to fuel.

If you want the Range Rover Sport with the highest claimed fuel economy, head straight for the P400e plug-in hybrid, with up to 84.1mpg claimed by Land Rover. However, you’ll need to be making full use of that electric motor to get anywhere near this. If you don’t, you’ll primarily be running on a powerful petrol engine that will struggle to see more near 30mpg.

During our time of testing, this plug-in hybrid with a fully charged battery achieved the same 28.6mpg figure as the SDV8 over a mixture of town and motorway roads. This could seem like a lot of effort in order to achieve the same level of fuel efficiency, but this will make more sense if you stick around town and city environments. The Save function hidden in the My EV menu on the touchscreen also failed to conserve battery power when driving on the motorway.

Range Rover Sport P400e screen

The rest of the petrol line-up is thirsty. The Si4 returns between 24.0mpg and 26.1mpg, the P400 24.9-27.4mpg and the two supercharged V8s a lowly 18.8-20.2mpg. You’ll be frequenting the petrol station very regularly with one of these. Figures for the P360 are yet to be released.

The diesels fare better. The SDV6 returns 29.3-32mpg, while the more powerful SDV8 claims 25.5-27.0mpg. Like we said, there’s no good option for running costs day to day. Servicing and maintenance will likely be costly as well, but it’s worth paying to make sure the car stays in good condition.

As with fuel consumption, CO2 emissions for the Range Rover Sport are high, again excluding the P400e PHEV, which produces a claimed 74-85g/km thanks to that electric motor. The 2.0-litre Si4 emits 245-266g/km, while the more powerful P400 actually produces less at 234-258g/km. It’s another story for the supercharged V8s, between 315 and 338g/km. The upcoming P360 with the lower-powered six-cylinder engine is yet to be tested.

The diesels are slightly lower, with the SDV6 the best performer here, emitting 232-256g/km, while the SDV8 is quite a bit higher at 275-291g/km.

Reliability

  • Several recalls for the Range Rover Sport
  • Solid build, but quality can be patchy
  • Ensure everything’s as it should be if buying used

While the Range Rover Sport certainly looks a premium product from the outside, and there are plenty of plush materials and a solid feel from behind the wheel, Land Rover suffers from a patchy reputation when it comes to the reliability of its cars, and the Sport has suffered a similar fate. There have been several recalls issues for the car – admittedly in small numbers each time – but it’s worth checking any remedial work has been done on a car you might be buying on the used market.

Issues range from fuel leaks and fire risks to the indicators not working or issues with the autonomous emergency braking system. Whatever it is, it should have been carried out under the car’s warranty.
