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

Diesel engines 36.2 - 46.3 mpg
  • No low-spec trim, diesel engines only
  • Servicing and maintenance should be cheap
  • We’re expecting favourable leasing costs

Predictably, 1.6 litre-engined versions take the average fuel consumption and CO2 honours, with figures of 57.6 mpg and 128g/km.

Renault insists, however, that the 2.0 dCi Dynamique S Nav 5dr X-Tronic is expected to be the most popular trim and engine combination, and that equates to 47.9mpg and 156g/km (meaning comparatively crippling VED and benefit-in-kind costs), with residual values pegged at around 40% after three years and 30,000 miles, depending on precise version.

Renault Koleos

The lowest CO2 output on offer here is 128g/km, which isn’t anywhere near what we’d class as impressive. That’s for the 1.6-litre diesel, but the version Renault expects to be most popular – the 2.0-litre diesel – is responsible for carbon dioxide emissions of 158g/km.

No hybrid versions are available yet, and Renault has yet to confirm if and when the petrol version (sold in South Korea, where it’s built) is coming to the UK.

  • It’s a new car to us, but it’s made in its millions South Korea
  • Tried and tested engines mean fundamental reliability
  • Previous (unrelated) Koleos suffered with electrical niggles…

Renault Koleos

Unfortunately the Koleos has historically suffered somewhat when it comes to reliability. There is a vast array of electronic systems on the car so loads to go wrong there.

While the statistics we’ve found, such as 30% of MoT failures being for electrical issues, relate to the old car, it’s an issue that Renault in general is still known for in its modern models.

However, the carmaker says it’s taking steps to address this, so we’re willing to be convinced otherwise with the new model.
