In Europe, Honda has recently introduced a 2.2l diesel in the CR-V and Accord. Pretty impressive mileage for the CR-V with a claimed 34 mpg in the city and 49 mpg on the highway. (4WD with 5-speed manual.)delphi7x10 said:
Obviously this 4 cylinder would be too small for the Ridgeline, but Honda is definitely getting some experience with diesel.
