Fuel economy

Petrol engines 33.2 - 47.0 mpg
Diesel engines 48.7 - 60.1 mpg
  • Extremely low cash and PCP finance costs
  • Strong diesel fuel economy, petrols okay
  • LPG Bi-Fuel available from around £400

Although the Duster's running costs might not be the lowest - there's no plug-in hybrid (PHEV) version, for instance - factor-in the very low cash prices and finance costs and this must be one of – if not the – cheapest family-sized SUVs to be in.

Under the more stringent WLTP fuel efficiency tests that are designed to better replicate real-world driving, the front-wheel drive (4x2) Blue dCi 115 diesel performs best with an official figure of 57.6-57.9mpg. With four-wheel drive, the 4x4 versions aren't too far behind at 50.4-51.3mpg.

Of the petrol engines, the TCe 100 ranges between 45.5-46.3mpg, the TCe 130 from 42.8-43.3mpg and the 4x2 TCe 150 also at 43.3mpg. If you want your TCe 150 with four-wheel drive, it drops to 40.0mpg.

Worst performers economy-wise are the new-for-2020 Liquified Petroleum Gas (LPG) Bi-Fuel models. These can run on petrol or LPG and are based on the TCe 100 engine, but note that economy drops to 35.3mpg when they're using LPG. But mitigating against this additional thirst is the cheaper price at the pumps – LPG typically costs between a half and two-thirds the price of unleaded petrol. Bear in mind the relative scarcity of LPG pumps in the UK – around 1,400 where there were three times as many 20 years ago.

Dacia says that for owners of Bi-Fuel cars, cost savings for those running exclusively on LPG work out at around £1,650 over the course of three years on an average annual mileage. Overall, the Duster range isn't as impressive in the miles per pound ratings as we would have expected, given its economical status, with a spread of 7.1 - 12.1 mpp.

Dacia also offers one to four-year servicing packs (one service per year), which should keep maintenance costs down.

Off-roader emissions are typically higher than equivalent hatchbacks, due to their additional weight and bluff aerodynamics and that goes some way to explaining the Duster’s higher CO2 output.

The lowest CO2 emissions come courtesy of the 4x2 Blue dCi 115 at 128g/km, with the TCe 100 Bi-Fuel only just behind at 129g/km. Worst of the range, although not by a significant margin, is the 4x4 TCe 150 petrol at 162g/km - that's 13g/km higher than the same model fitted with front-wheel drive.

All Dusters are equipped with stop-start technology to prevent fuel being used when the vehicle is stationary.

How reliable is the Duster?

  • Dacia uses Renault engines and equipment
  • Basic Duster has only experienced one recall
  • Above-average reliability, according to JD Power

Despite parent company Renault not previously enjoying the best of reputations, Dacia's reputation for ruggedness translates into above-average reliability according to the 2019 JD Power UK Vehicle dependability survey. beating premium players such as Land Rover, BMW, Mercedes-Benz and Audi – as well as parent company, Renault.

Why is the Renault link important? Because the Duster's underpinnings, electrical components, safety systems, engines and numerous other parts are all ex- or current Renault fixtures and fittings.

The second-generation Duster gains a lot of technology new to the brand such as keyless entry, automatic headlights and climate control – all new to the Dacia range – though as this isn’t cutting edge kit, we don’t anticipate too many problems.
