Subaru debuted its new 2.0L diesel boxer engine earlier this year in the Legacy and Outback, and soon it will also be offered in the Forester and Impreza, though only in Europe. These two latest models to feature the unique horizontally opposed oil-burning engines will debut at the Paris Motor Show next month. The Forester 2.0D will offer 147 horsepower and 258 lb-ft of torque while returning 44.8 combined mpg in the European cycle, which is class-leading for a small CUV over there, while the Impreza 2.0D offers 148 hp and 258 lb-ft (fuel economy for the Impreza 2.0D was not released for some reason). The diesel Forester will hit showrooms later this month while Euro shoppers will have to wait until January for the diesel Impreza. While we certainly hope Subaru is tweaking its 2.0L diesel boxer engine to meet emissions standards in all 50 U.S. states, we haven't heard one word about it.
