MPG, running costs & CO2 Rating

4.0 out of 5

Previous Renault Meganes – particularly the diesels – have always been among the most efficient cars in their class and this latest version looks to maintain that position. However, they haven’t always been good at retaining value, but the reduced maintenance and repair costs of the latest version contributes to increased residual values compared to its predecessors.

Renault Megane MPG & CO2

The most economical version of the Megane is the 1.5-litre 113bhp dCi 115 diesel with a six-speed manual gearbox. Renault claims up to 62.8mpg and CO2 emissions as low as 119g/km on the Play model. Step up to the top-of-the-range GT Line model with an automatic gearbox and economy sits at 58.9mpg with emissions at 134g/km; visits to fuel stations shouldn’t be too frequent as a result.

The 138bhp 1.3-litre petrol engine returns 46.3mpg in the Play model, while specifying the optional automatic gearbox brings this down to 44.1mpg. CO2 emissions range from 137g/km to 150g/km, but the petrol and diesel engines offer broadly the same Benefit-in-Kind (BiK) bands as there’s a surcharge on diesels. A plug-in hybrid model, offering 31 miles of electric range, will join the range in August 2020.

After the first year's CO2-based road tax (generally included in the on-the-road price), all Renault Meganes cost £150 a year to tax. 


The lowest Megane insurance group is 14 for the Play with the 1.5-litre diesel engine, while the 1.3-litre TCe 140 petrol sits in group 18 to 19.


Renault lengthened its standard warranty at the end of 2019, so the Megane is covered by a five-year/100,000 mile warranty. This stacks up well against rivals, beating the three years of cover offered with the Ford Focus and Volkswagen Golf, while matching the Hyundai i30 and Toyota Corolla's five years of cover. Renault also includes three years of roadside assistance.


The Renault Megane requires a service every year or 12,000 miles, and Renault offers affordable service plans for all its cars. Its EasyLife Pack covers servicing for three years (or 30,000 miles, whichever comes first) for £299, but is not transferable if you sell the car.
