For what its worth, the whole SGE SIDI petrol range of engines were developed between SAIC (Who I think had the cash) and GM (Who had the Tech). They are the petrol turbo 1.0, 1.4 and 1.5 engines dating from 2015-6. The MGE 1.6 SIDI petrol turbo is an earlier engine - a solo GM effort, I think - dating from ~2013.
It is a shame to have seen the engineering excellence of the designs - balance shaft(s) in the 1.0 (1) and 1.6 (2) - deleted with time. IMO GM always knew how to design and produce good engines. I guess the bean counters now rule as in so many industries.
