When I say small engine, I say 0.8ltr, 1.0ltr. 2.0ltr in 97% of the world is considered fairly large engine and should not have any issues.Thats why I say design....some models issues, some dont. Are the euros as heavy as , say the caddys that were having issues? I would think some of these heavy cars are under boost most of the time by design, to make them "feel" like the v6 they are replacing.
And yes they are heavy. BMW 5 series, 3 series, MB E class, etc. None of those have LSPI issue and probably packing more weight than Caddy.
