I can't comment on the design of an engine, I don't know enough. But just looking at the numbers you can definately say the subaru engine is inferior, if you're Jeremy Clarkson and you're compairing it to the BMW diesel in the 535d with peak torque at 2000 rpm and peak power at 4400 rpm.
But, IMHO torque at low rpm is really what you want if you're on ecomodder.
Not so long ago a new jetta TDI was driven across all 48 states, they averaged 58 mpg, hitting 60 mpg on some tanks. Both the new Jetta TDI and the Subaru Legacy sedan get similar fuel economy on the Euro cycle.
33.6/49 USMPG for the Legacy
33.1/52 USMPG for the Jetta
It should be noted that the Subaru have 5 speeds and is awd, whereas the TDI have 6 and is front wheel drive.
So I would really not be surprised to see ecomodders pulling over 50 mpg on the highway with that car.
