They're not as fast as the old blue efficiency engine, which used to be 6.2 (0-62mph). This is half a second slower, and half a second's a lot, know what I mean (to 62mph it's 6.7)? So personally, stick with the blue efficiency engine, unless you can't get it, 'cos they don't do it any-more. Unless you want the old model.
The older model is the better car, in my opinion. From 2013 they stopped it. 2013 was the last time you could get it. From 2014 they started with the blue-tech engine.
