not a fan of it either, but it doesnt really effect me to much
I hate the lack of power when I really need (like entering highway or passing a vehicle)
its a 2.5L thats only pushing 170hp. thats the problem. you couple that into an AWD with large tires, and you are asking for a turtle.
This is probably why they introduced "sport" mode in later models.
they added the sport mode because the basic program (MAP) is designed to drop the engine RPM quickly, to save fuel - not because the car isnt "fast/powerful" enough.
My solution is to press the overdrive button, which I "feel" it is adding too much stress to the car
its not stress per say. but i wouldnt do it every day. all you are doing is simply downshifting as its designed too - but it refuses to do it because its designed to save fuel by keeping the RPM's down.
I hate the noise of the poor engine when I press the pedal, the rpm increases, but the car stands still.
again, thats all programing. the MAPs that are in the computers are shooting the engine up, and slowly engaging the transmission.
if you allowed the engine and tranny to engage at a high RPM - you'd blow your AWD system out. its a small SUV - what did you expect?
I can't tow even a small tent trailer. Because that CVT belt cannot handle too much torque!
its not just the tranny. its the awd system. like every car, we have the engine & tranny right? well in our small AWD we have a tiny transaxle(which takes the transmissions spinning gears and robs some of the power to send it to the rear wheels via a shaft). from there you have the rear differential with a clutch-pack that cant take too much abuse, and gears. connected to the rear differential are 2 CV-Joints.
I can live with these problems if that CVT technology saves fuel (what it is designed for). My Rogue is currently at 11.2 lt/100km and I am using ALL the fuel saving techniques.
the CVT isnt all about saving fuel. the CVT is about removing weight, moving/spining pieces of metal, and reducing the complexity of a transmission. if anything - its a cost savings for Nissan. the real fuel savings comes from the PROGRAMING of the MAPs. like on my racebike, i hook it up to a computer and i can re-map the whole computer on the bike to run like a fuel burning beast, or a tame fuel sipping p****-mobile.
I think (I may be wrong), CVT technology is like Hybrid/electric cars. The idea is promising, but it needs more time to reach to a certain maturity.
BINGO.
in conclusion: the current market of buyers wants 2 things: INFOTAINMENT, AND GOOD MPG's. with the two, will come pluses and minuses. with the two will come new technology and issues. BUT LETS FORGET THE INFOTAINMENT ASPECT OF THE CONVERSATION AND FOCUS ONLY ON THE MPG's. part of the issues is working out the bugs. well in the engine design room - the bugs have been pretty much worked out since this engine has been around for a while. hell, engines have only slowly changed in design, thus allowing engineers to foresee issues- in any car maker. the transmissions have been changing drastically year after year. because at the end of the day - the drive-train (aside from the engine) is still a relatively growing field. unlike engines, there is still a TON of room for advancement and growth. there is still a TON of things that can be done to improve "cars" in general. from awd advancements, to slip-systems, electronic sensors, and how each is positioned were, engaged how/when, etc = the art and design or transferring engine power into making the car move = is absolutely F-ing insanely complicated. and the more modern things become - the more complicated it gets. and the more people demand better fuel economy, the more stress is placed on drain-train components - why? because the modern engine is pretty much as good as it gets. its my honest opinion that we wont be able to squeeze much more out of our engines in order to appease the MPG hunting crowds. 70% of power is already wasted in a modern engine, i dont see that changing anytime soon. so the only place left to advance and change is the transmissions. and since every year or so a new transmission is created and used = you have new issues.
specifically in our rogue, i see this issue: the population demanded BETTER FUEL ECONOMY - and the nissan engineers over reacted by placing MAPs in our car to drop the engine RPM(thus using less fuel), thus increasing the stress on our transmission - which creates a new set of problems = the transmission is then forced to be in specific gear ratio's that will allow the engine to not bog down. so what you have is an engine & transmission thats programed to drive at a turtles pace, the driver then over-compensates by apply even more throttle - causing the transmission to re-hunt a new gear ratio and the engine reacts by shooting the RPM up.
bottom line is this: NISSAN OVER COMPLICATED THINGS. THEY TRIED TO CREATE A HARMONIOUS, SLOW, FUEL SAVING SYSTEM, HOPING PEOPLE WILL NOT CRAVE THE 'NEED FOR SPEED'. NEWS FLASH: nissan used the wrong engine in the rogue (which has a RPM dropping transmission & electronic programing(maps) to add to the problem!) if the engine had more power powerful, it would be able to keep the RPM's down while still able to have high power, thus allowing the transmission to turn as slowly as it craves, and wouldnt require the driver to stomp on the throttle to achieve normal driving speeds.
the rogue is a total pain in the @ss. its small, so you cant put too powerful of an engine (like the vq3.5). it would simply twist the uni-body frame to much and blow out our transmission. you cant put too powerful of an transmission to compensate for the 3.5L power you want, it wouldnt have the room for both. and at the same time you want all of those features, plus awd, and to save gas. something has to give. so they chose this CVT program. it works. but the programing sucks. if they changed the programing(maps) the MPG's would go down.
again, you cant have it all in this small sentra based SUV.
