I could not agree more. Depending on the engine and application they look good on paper and thats about it. They cost more, eat more gas, and are more complicated and will likely cost you more down the road in repairs.I'm not a huge fan of Turbo engines...period. We have a Turbo Sonic. It gets EPA mileage if you really REALLY baby it. Drive it even 'normal' and you are going to do worse. Case in point, we have a 2013 Focus and a 2013 Sonic. Driving them the same way, the non-tubro Focus gets EPA while the Sonic doesn't. Go really, REALLY conservative, and the Focus is slightly better than EPA, but that is when the Sonic jumps.
I agree with some posters that the Turbos look better on paper than they perform in real life. Having a relative with one and having test driven both the 1.6 and 2.0 Escapes (along with our Turbo sonic) just enforce to me that Modern Turbos are slightly harder to get epa numbers out of than NA engines, and feel like they have slightly less power than advertised.
