I hope Honda brings the diesel version of the CR-V to the US eventually. I would have purchased a diesel CR-V in a heartbeat instead of my gasoline EX in 2008. If Acura were to release a diesel version of the MDX, that would probably be my next vehicle purchase.
The trade-off with modern diesel engines seems to be: 1) more torque; 2) longer engine life?; and 3) higher mileage; vs. price premium for the fuel.
