Low figures relate to the least economical version; high to the most economical. Based on WLTP combined fuel economy for versions of this car made since September 2017 only, and typical current fuel or electricity costs.

Fuel economy

Petrol engines 26.2 - 30.1 mpg
Diesel engines 34.4 - 42.7 mpg
  • Diesels cheaper to run on paper
  • Better economy and longer service intervals
  • AWD D150 and D180 offer identical mpg

No prizes for guessing the best performer here – the two-wheel drive D150 with a manual gearbox. This clocks in 42.4mpg on the official WLTP economy test. The all-wheel drive model sees a small drop down to 41.3mpg, while adding the automatic gearbox see this dip below 40mpg, to 39.2mpg.

The D180 manual claims 40.7mpg and 39.2mpg for the automatic, while the most powerful D240, is still more frugal than the petrols – Jaguar says 37.0mpg.

The P200 claims the highest out of the petrol engines, with 30.1mpg dropping slightly to 29.7mpg on the P250, with 27.9 for the P300. In terms of servicing the petrol engines have intervals half the length of the diesels, so that’s also worth considering too if running costs are an issue.

Miles per pound

In terms of miles per pound, the entry-level D150 in front-wheel drive form will take you 8.0 - 8.6 mpp, which compares with a 5.6 - 6.0 mpp for the HSE P300 AWD.

Compare that with an Audi Q3 Sport 35 at 8.2 - 8.5 mpp – and if you want a fast petrol one, you're limited to the 230hp Sport 45 or the altogether more potent 400hp RS Q3, as there's nothing around the 300hp offered by the E-Pace P300. The RS Q3 goes 5.9 mpp.

Green credentials

There’s a split here between cars tested before WLTP came about in 2018, and after, which is worth considering. As you’d imagine a diesel-engined Jaguar E-Pace produces less CO2 than a petrol one, with the manual, two-wheel drive D150 taking the honours of lowest output of 175g/km of CO2 (124g/km pre-2018).

That said, the D150 and D180 are closely matched if you pick AWD with a manual or automatic gearbox, expect between 179-189g/km of CO2 here. As with the fuel economy, the most powerful D240 diesel has a lower CO2 output than any of the petrols - with 201g/km.

The petrol-engined P200 and P250 are close with 213- and 216g/km respectively, with the P300 up at 230g/km.

Reliability

  • Underpinnings shared with the Range Rover Evoque
  • Ingenium petrol and diesel engines used elsewhere
  • Not a traditional Jaguar strong point

In some ways it’s hard to say how the Jaguar E-Pace will fare but in other ways not so – the platform it is based on has been around for some time and the engines it uses, although reasonably new, have been used elsewhere. That said Jaguar Land Rover hasn’t got the most sparkling reputation for reliability.

The E-Pace shares its underpinnings with the Range Rover Evoque, a car that has been recalled by the DVSA six times for a variety of electrical, steering and fuel- leak related problems. In theory, that means the E-Pace should have had these issues ironed out, but it too has been the subject of four recalls since 2017. Any remedial work will have been taken care of at the time. The latest recall in 2020 involved replacing the right hand front seat, due to a missing fastener or incorrectly assembled one.

If you want some peace of mind the E-Pace comes with a three-year, 60,000-mile warranty
