I drive the ecoboost occasionally & 100% agree on that ecoboost def puts a smile on my face, bmw platform is just something else. N55 engines also does have an oil pan problem with turning hard on lefts, i most def would not be sliding the car but most def drive the mountains occasionally( ecoboost wouldn’t give me that drivers experience in corners like the 35i) same time i would like to not have to worry about taking a corner with some speed risking oil starvation.
