Ford recently federalized a 3.2L I-5 diesel for the Transit van, where it makes 185 hp and 350 lb-ft, but by comparison, that doesn’t even out-twist the smaller 2.8L Duramax I-4 found in the GMC Canyon and Chevrolet Colorado. For a diesel Ford F-150 to be competitive, it would need to turn the wick up on the 3.2L Power Stroke.
