Je vous livre la conclusion du test fait par Autocar (www.autocar.co.uk, un magazine que j'aime bien) :
"Should I buy one?
Our only regret is that, like all hot diesels, the Renaultsport Megane dCi lacks a bit of that traditional hot hatchback piquancy. It feels brisk rather than fast, and it doesn't have any of the aural performance appeal of a petrol-powered 'GTi Turbo'.
However, the buyers of this new breed of performance car are ruled by more grounded considerations. If you're one of them, the fact that this Megane goes 10 miles further on every gallon of fuel than its petrol counterpart, can put 600 miles between fuel stops, will cost fleet drivers at least £200 a year less to tax, and is damn near as fast and as capable dynamically as a Megane 225, are probably all the justifications you'll need to put your name down for one.
If you do, you'll certainly be buying the most broadly talented hot diesel anyone's brought to market to date."
En gros, ils disent ce qu'on disait plus haut : c'est une excellente bagnole pour ceux qui ont des considerations du genre "consommation" ou "taxes sur la bagnole" (sur le niveau de Co2 en UK pour les voitures de fonction).
Mais elle manque bien sur d'un peu de piment, un certain je-ne-sais-quoi...et a en trop des claquements le matin a froid et une fumee noiratre a l'échappement 
! (je sais de quoi je parle, ma bagnole de tous les jours est une passat TDI...)
