I wonder if this notion comes from the 80s, when engines with turbos had lower compression ratios for reliability. Today's turbocharged motors have higher compression ratios than in the malaise era, and the turbos have a lot less lag. Turbos no longer mean you have to sacrifice fuel economy for performance (unless you have a lead foot).
replyNope, just engineering to do not much more for warranty. Turbo engines arent inherently unreliable (tho you might need to replace the turbo itself every 100-200k so still more expensive to maintain), just need to build extra strong block and components if you want it to run for a long time.
replyAnd why would company do that if that would put it far over warranty period?
>Turbos no longer mean you have to sacrifice fuel economy for performance (unless you have a lead foot).
replyThat's incorrect. Virtually every turbo'd gas car runs slightly richer than stoich to use the unburnt fuel to manage temp/knock. Diesels, you actually get more efficiency out of with a turbo for free. With gas you're practically guaranteed to be throwing fuel out the pipe.
