For example my Subaru Impreza has a boxer engine in it, Subaru uses the boxer because it began making planes before cars. So essentially I have a modern day aviation engine in my car, but why havnt real aviation engines followed along?
I had a WRX for three years. In terms of value for money and function, it's the worst car I've ever owned. The engine contributed towards that due to it's "lumpy" power delivery. Never realised the origins of the subaru boxer engine before. It was also very very thirsty, returning an overall average of 23mpg.
