I'm not entirely convinced that Ford got this engine right at the first meeting - tax category isn't eveything. The use of a turbocharger on a petrol engine for "school run" applications is questionable due to potential reliability problems. The exhaust gas temperatures far exceed those found in most diesel applications and turbochargers fitted to petrol engines seldom last as long, on average.
Engine balance is another big question and I thoroughly dislike engines which lack at least primary balance. Obviously we can't all own straight sixes which are almost perfectly balanced but the 3 cyl without a balance shaft is poor - and not a lot better with a balance shaft. Remember all of the engine components, turbocharger, alternator, fuel control etc are being shaken to bits during their operating life. One failure here is expensive.
The maximum rev limit should be a big clue as to how large the out of balance forces are. I haven't checked this engine, but a well balanced 3 of that size should be safe to 7000 rpm.
Finally, although I admire Ford's engineering enterprise, I once unwisely purchased a Ford CVH. The detail engineering, especially the 19 tooth belt timing drive was truly dreadful and the engine was worn out at 100k miles despite good maintenance. A fair engineering concept ruined by cost cutting. No doubt the work of Ford accountants - but I will never again purchase anything from this organisiation.
We'll see how it survives the tarmac jungle - but it's not for me.
