The cheapest Megane CC to run is the 110dCi diesel. Thanks to its new EDC double clutch automatic it averages 56.5mpg while emitting a low 130g/km of CO2. This means it slips into the cheapest 18% company car tax bracket and VED Band E for road tax. The most popular petrol 1.4-litre TCe 130 model, meanwhile, averages 38.7mpg while emitting 169g/km of CO2.

This makes it liable for the higher 21% company car tax, while attracting the higher VED Band H road tax. The most power 158bhp 2.0-litre diesel under the bonnet of the dCi 160 also has reasonable running costs. Averaging 47.9mpg, it emits 155g/km of CO2 which means company car users pay the 22% benefit-in-kind car tax while road tax is in Band G.

The kindest convertible to the environment is the 109bhp 1.6-litre diesel with its all-new twin clutch transmission. Emitting just 130g/km of CO2 is a commendable achievement from what is quite a heavy car.

Renault has struggled with quality in recent history. The brand frequently underperforms in owner satisfaction surveys. The last Megane was no exception. It was tough mechanically, but fell down on niggling faults like issues with the aircon. The CC, specifically, has also come under criticism from our readers who have reported leaking roofs and electrical gremlins.

The current Megane should prove much better. A culture of quality is now deeply engrained in the Renault and new models are developed with improved quality as a priority. Only time will tell how much better the new cars perform.
