It looks like the 2020 Subaru will probably offer Start Stop technology like the 2019 Forrester.. Some auto reviewers do not like this feature- and at least intuitively, turning a car's engine off and on in bumper to bumper traffic can't be great for engine wear. However there is potentially significant gas savings:

Direct fuel injection may involve a similar tradeoff in fuel economy/performance versus longevity/maintenance costs.
Many of these technologies to keep the gas engine relevant in age of devastating climate change- beckons at least two questions: (1) What is the actual future of gas engines? and (2) What is Subaru's alternative fuels/electric strategy? Other than the new Crosstrek, the company doesn't seem to have one- and that may bode ill for their long term future. You would think a company that stresses the Environment in their PR and has a commitment to zero land fill would and could do better.
Still with the oil and gas lobby as strong as ever, and in America where it is sometimes cheaper to run on gas than electricity- the love of gas engines may not- unfortunately- die soon.
