4K at how fast? My Nitro that can tow turns about 2.3K at 75mph.To be completely fair - for those considering a Rogue or the Vibe or the big brother Murano, the 4wd is nice, gas mpg ok, I got used to the 'single gear' fairly quickly, its not as bad as it seems. Just NOT a tow vehicle. We were towing the previously mentioned load up I-95 from Delray beach to New England. We made it as far as North Carolina, (where 95 stops being perfectly flat). The first small hill loaded it right up. I was glad we didnt push it into west virginia/penn area where it gets really steep. Even on the flat areas though, the revs were running about 4k, I could not get them down below that (normal cruise is about 1500.) No other issues other than towing. It had about 50k on the miles when we did this, now it has 75k and is no worse for it.
But then again, what's redline of your motor?
