I looked at a new 2013 Rogue a few weeks ago. Before I buy I always look at and drive the competition. Personally, I'm a Mazda guy but, if there is another brand that is better for me, then it makes sense to get it.
The 2012-14 Rogue has 170 HP / 175 Torque @ 4400RPM, fairly standard in the CUV catagory. Gas mileage will vary depending on driving style, weight added to the vehicle, terrain, weather temp, altitude, etc. EPA ratings are never correct.
A few things swayed me to the 2014 Mazda CX-5 GT. The drive: Mazda has the sporty road handling that Honda, Toyota, Nissan and a few others are missing. The interior layout is excellent, the controls are pretty much exactly where I want them to be. Having the GT with Tech pack I'm spoiled by having all the options possible. Engine in the CX-5 is a SkyActiv 2.5L with 184 HP / 185 Torque at 3250RPM, so not only does it have more power but you get to that power faster. Capacity-wise with the 2nd row up the Rogue has 39.3cu. ft. and the CX-5 has 34cu. ft., not a big difference. Now for the looks, which is again a personal thing, however, I again think it looks a lot better design-wise.
All that said, a good deal on a Rogue is fine. If the car fits, drive it
...to add: the Rogue would be my personal 2nd choice.
