Well, if BMW can put a 4 cylinder in a 5 series weighing over 4 Grand yet provide the similar torque and HP then you see where the CAFE standards are leading us. I bought the last 6 cylinder 5 series in 2011. Smaller, 4 cylinder diesels will likely be the norm and watch for Ford 150s to arrive WITHOUT a V8 pretty soon. But, heavy Rvs need TORQUE first then HP and gearing and the Sprinters with 5sp/6 cyl turbos have done well hauling 11,000 pls lbs. I say, caveat emptor --don't be intimidated by advertising smokescreens. If possible...!!
There are Many Features of an engine: hp, torque, cooling capacity, longevity, reliability, weight, good looks, and on and on.
We measure the work and engine will do (power) in horsepower whether it is a diesel, gas, 2 stroke, 4 stroke, electric, rotary....
In a drag race the Chevrolet Express Van Class B RV will leave a Sprinter Class B RV in the Dust. But going up a long significant incline, mountain road the Sprinter will pass the Express Van. Why? The Express Van does not have the cooling capacity. If it did, it would leave the Sprinter.
A 4 cylinder diesel would be fine, 'Depending' on what the other features are other than hp.
