My last car an '05 Audi A4 1.8t performed perfectly with no issues until I sold it with 150,000++ on the clock. I never keep cars as long as that one, but it was the best car I have ever owned and I didn't want to get rid of it. I am now an Audi person and bought a new one. Cars have come a VERY long way and most don't need anything for well over 100,000 miles these days.

I'm ok with turbo in general. It's still a 4 cyclinder and still pulls like one.

Maybe Trump will put the gas milage requirements back to where they were and we can get back to reliable, torquey, long lasting, smooth, and fast V6's.

We have been driving a turbo Sonata for over six years now and frankly it has been better than the sixes and eights of the past. I don't expect a longevity issue and can tell you this will be my preferred engine going forward.

You should be less worried about turbos but more about direct fuel injection. As before, valves were flushed by air/fuel mixture and kept clean. Now, with direct injection, valves tend to rather quickly build up carbon deposits on them, resulting in lowered performance down the road.

The main issue I have with turbos is the heat they generate.
They tend to cook everything in the vicinity.

So, for long life I prefer NA, the bigger the better.
But I do own a turbo car that's almost 30 years old.

Ain't gonna happen even if mpg requirements are rolled back. Auto makers have spent hundreds of millions developing these new engines and they won't let them sit on the back burner not generating revenue.

I traded in a 2005 1.8T Passat with 140K miles on. Synthetic changes every 5K with no issues. I now have a 2015 1.8T Passat with 35K on it and have no doubt it will go over 100K without any issue. The oil change requirement is now 10K and that's what I do.

The types of money these companies are asking for in a four banger is crazy. The new Merc E400 is a turbo fourbanger and 1 sec slower to 60 than the prior v6 E350. They are asking $65-70k for the new four banger.

PASS!

The thought of having a 4 in an E-class is just repulsive. What are they gonna put in a C?Luxury cars used to distinguish themselves by their engines. Now we see Jaguars with a 4.
