Replying to: coldcranker (Sep 15, 2008 7:53 pm) That's very tall gearing, and should be good for economy, but remember the Rogue only burns 2.5 liters of air/fuel mix each revolution of the crank.   Plus we'd have to look at how rich (or lean) that mixture had to be to carry that load, and the Rogue is lighter. If you have a trip computer and set your cruise control you can see how the mileage numbers drop when you're going uphill, and climb while you drive downhill, all due to the lean or rich fuel mix.   RPM is just one factor.   Let's look at an example. Compare a Corvette to the Enclave.   Corvette has ultra-tall gearing and great aerodynamics and weighs 1700 lbs less than the Buick, yet EPA highway figures are the same. Huh?   Why? Displacement.   Each revolution of the crank it's sucking in nearly double the air/fuel mix, and you can't go too lean else you'll torch the pistons in your 'vette.   The Rogue will simply get better mileage on the highway, naturally, as it should.

Replying to: ateixeira (Sep 16, 2008 11:33 am) Sounds OK, except for the comments on lean and rich. The engine doesn't stray too far from stoichiometric under any conditions, since emissions are tightly controlled. Lean and rich refer to the air/fuel ratio at any given time, and that is nearly constant. As the butterfly throttle valve opens up inside the air intake, allowing more air in, the fuel injectors allow more fuel to flow, keeping air/fuel ratio constant no matter the road conditions.   A vehicle's highway MPG is governed greatly by how much aero drag it has to push through, and how close to the peak torque point it can operate at, where its most efficient, as pumping losses in the air intake are lowest there.

Replying to: coldcranker (Sep 16, 2008 7:45 pm) Yeah, I guess it's using more air and more fuel to climb up a hill, though RPMs don't usually change.   When you have a Trip Computer and get bored on a long trip, you pay attention to things like that.
#6784 of 7126 Rogue towing by psfod3 Sep 17, 2008 (7:38 pm)
I am about to get a 09 Rogue. I have a small boat with engine that I would like to tow. I have seen to specs one stateing a 1000lbs limit and another set at1500lbs. Does anyone know which is correct. I have never seen a Rogue with a hitch. I have only seen one Murano with a hitch even though it is rated at 3500lbs. I am wondering if there is a issue with the cvt that makes it unsuitable for towing. Replies to this message: ateixeira (Sep 18, 2008 6:51 am)

Replying to: psfod3 (Sep 17, 2008 7:38 pm) This is an educated guess, but...   It's probably 1000 lbs limit with no trailer brakes, and 1500 lbs when your trailer is equipped with trailer brakes.   Problem is, small trailers often do not have trailer brakes.   Funny thing is this is in the small print for even some full sized trucks!   I don't think the 1000 lb limit has anything to do with the CVT, especially since the Murano has a CVT and can pull 3500 lbs.
#6786 of 7126 Consumer Reports reliability ratings: small SUVs by chelentano Sep 28, 2008 (10:18 am)
CR: "Reliability of new models by category   These charts help you compare our Predicted Reliability Ratings for 2008 models within the same category. To create them, we calculate an overall reliability score for each of the three newest model years (2005, 2006, and 2007) provided the vehicle hasn't changed significantly in that time. Three-year data are a good predictor since most new models for this year are essentially the same as earlier models. Extra weight is given to some components, including the engine (major problems), cooling, transmission (major problems), and drive system. Each overall reliability score is compared with the average of all vehicles in our survey for that model year. The yearly differences are combined to give the Predicted Reliability score shown as percent. This overall average is the zero line in the charts. The bars represent the percentage by which each model was better or worse than the average.   A broken bar indicates a percentage that extends beyond the chart. In cases where a model was new or redesigned last year, or where we simply lack data for more years, we might rely on one model year's data. Those models are labeled with an asterisk (*).   Most brand-new models don't appear here because they have yet to establish a track record. Models redesigned for 2008 are shown with (2007) in their model name. In rare instances, we make a prediction for a new or redesigned model if the manufacturer's or model's history is typically outstanding."   Replies to this message: ateixeira (Oct 02, 2008 11:47 am)

#6788 of 7126 Murano poor crash results by psfod3 Sep 30, 2008 (4:38 pm)
Nissan and many articles show the Murano as a top pick in the insurance institutes off set crash results. This is true but the NHTSA only give the Murano a 4 star rating for both the driver and front passenger in the 09 model(08 was 5 stars for both). This is awful for a 09 model. There is no excuse for that. In checking the NHTSA for small and midsize suvs it is one of the only cars with a 4 star rating. The 08 and 09 Rogue had 5 safety stars for driver a 4 for front passenger

Replying to: chelentano (Sep 28, 2008 10:18 am) You should add their overall scores as well. The order changes a lot.   Forester is their top rated compact SUV.   Reliability is important but the overall score includes many more criteria.
