Nice Post @ricknineg
Well, the BMW M10 engine, used on the e28 and e30 3 series, produced 80 to 130 hp naturally aspirated, a reinforced version, the m12, fitted with a turbocharger, reached 1100hp in F1 by 1985, it was one the first turbocharged engines in F1, and far from reliable. With heavy-duty, precision parts, modern engines achieve great reliability under high pressure from massive turbos, especially with water-methanol injection to improve engine life. I agree with you, it's a strange thing for Mercedes, but sadly there're almost no naturally aspirated models left. Enjoy your BMW V10, it's a modern marvel and much better than the latest turbo v8's.
