4x2 models have been given a 16 city, 23 highway rating from the EPA, while 4x4 models are expected to be a mpg lower in each.
Christ. Looks like I'll be marking the Pathfinder off my list of candidates. My 1997 Honda Passport 4x4 is rated for 16/19 (but in reality gets 17/23). I would have hoped that 8 years of development would have resulted in something with better fuel economy. Looks like it's actually worse. It looks like Nissan has bought into the "bigger is obviously better" mindset that has given us such abominations as the Excursion and H2.
Taking Nissan as an example, if a car company can boost engine size from ~160HP to 270HP over 8 years and maintain roughly the same fuel economy, why can't they make those same improvements to a 190-200HP engine and possibly result in 20/28mpg? I don't care for or need 270HP. Give me a mid-sized SUV with a 200HP engine and I'll be fine. Apparently I'm in the minority.
