That writer is definitely having an agenda - the first half of the article is informative and explains the trend well. In the second half it goes down hill when he claims the big V8s of the olden days were less stressed and that we can't expect the force induction engines to last past 150k without major repair bla bla bla only the rich get to drive V8 bla bla bla including the prez.
I don't know about you guys, but my 77 Camaro didn't last 150k miles on a V8, even my newer V8s usually blew a gasket or cracked a head between 150-200k.
I also do like my six cylinder in my porsche. I have never thought the V8 to be the ultimate engine, even owning brute muscle cars before, it was fun, but not in a refined or exciting motorsport way ...
