I'm looking at a new car which has the 1.2 Ecomotive engine. It boasts just over 80mpg, but have read a couple of comments on a review stating it doesn't achieve anywhere near that. Finding it hard to find much information on this engine to be honest..! Any one have any first hand experience with it? The car I'm looking at is a 2012 plate if that makes a difference! 
Obviously going over 70/80mph in a 1.2 diseal and I'm not going to be achieving decent MPG, but if driving at 60/70 surely I can achieve something close to the advertised figures? I'm aware it will be a slow car, not too fussed about speed just want something super economical as I'm driving around 400 miles/week!
Thanks guys/gals!
