I'm currently investigating a possible change from a 2012 Duratech powered plus4 to one with the new engine.
I stumbled over this article
http://www.thetruthaboutcars.com/2012/05/ask-an-engineer-gdi-problems-in-a-nutshell/Given posts flagging up possible issues with the siting of catalytic convertor giving rise to excess heat generation I'm starting to think it may better to sit on my hands for the time being and see how this new engine pans out.
Any views?
