They could start by making cars like the Forester and Impreza smaller and lighter. The difference in weight between my Impreza and the current one is well over 100kgs. There is no advancement in technology by just adding metal to make a car safer. Real advancement is making it safer without adding weight. Now I realise that weight can help in an accident, but this is also where better design and better legislation can help. Weight is bad for fuel economy no matter how good your engine technology may be.
Fuel economy in cars has improved because of better fuel injector technology and placement, superior ECU's and programming, reduced friction within the engine, better transmissions and better aerodynamics- leaving aside hybrids. But cars have all become heavier, negating part of the gains in this area. But there have been drawbacks to this.
Drive by wire has allowed engineers to over ride driver input, while conventional throttled cars have in built hesitation, and both can take ages to return to idle. This can also be blamed on emissions compliance. The result is that cars are increasingly not responding to the inputs of the driver in the quest for emissions and economy and this is not a good sign of things to come.

another reason for the 2.0 is the fact that subaru aims to cuts its fuel consumption across the range but 20% by 2014 i believe it was
