Renault Megane 1.2 TCe 115 GT Line: First drive

It may be longer, larger and wider than its predecessor, but with two new engines, Renault's 2012 Megane is the most economical model yet and manages to hide its size rather well. The 1.2-litre turbo petrol is pretty much a direct competitor to Ford's groundbreaking new Ecoboost 1.0-litre, while the 1.6-litre Energy dCi 130 is the most powerful diesel in its class despite chucking out just 104g/km of CO2. I travelled to Seville to find out if the tiny petrol engine can cope in a sizeable four door hatch.
