I am impressed with the BMW engines greater high rpm breathing capability.
The tests were run on 91 octane fuel.
It'll be interesting to see dyno's from 93 where available, just to see if either engine has tuning capable of utilizing the higher octane.
Caddies engine may be more sensitive to octane.
Caddy 2.0

BMW N20

good point on the octane - I actually think caddy is putting out a pretty decent product here, fully competitive; sales of course will be the ultimate judge...
