6spd around 75mph/120kmh what's your rpm?

Post by **matgaz** » Wed Apr 09, 2008 5:12 am

Just signed for a 2008 SL in Blueberry with the 6spd.

During my test drives, I found the gearing to be quite short with the 6spd but riding a motorcycle, I can get use to that.

From my test at 75mph/120kmh in 6th, I was around 3200rpm. I was wondering if this was gonna negatively affect my mpg - L/100km.

It not that big of an issue as I do most of my driving in town.

Any 6spd owners in here?

3200rpm is around what i get. versa's mpg starts to fall at that speed.

I'm at 78 mph for about 7 miles on my commute and its about 3600 rpm I believe. It definately hurts the mpg. Most of my commute is at 72-73 mph and its around 3300 rpm. I average about 31 mpg (and drive it rather hard in the city).

The 6th gear should definately be longer, would help a lot, 5th gear is almost usless.

Is it the same for the 4spd Auto and CVT?

6th is short because if it was any longer you wouldn't be able to accelerate while going 75mph/120km/h+. The engine doesn't have enough power at those speeds.

I cruise at about 2900rpm at 110km/h, the engine is not very audible at that speed, when I push it pass 110km/h, i can start hearing the engine really work. I pop the versa into 6th as soon as i get it to 60km/h.

6th at 60Kph???

CVT: 120 kph [70 mph] = ~2500 rpm for me iirc (may have to go out for a bit of a drive this afternoon )

Didn't we determine at some point that premature shifting of the 6-speed worsens fuel economy instead of improving it?

I goto 6th at 60km/h only if i know I won't have to slow down soon (like at 2am when no traffic) otherwise 6th is for 70km/h+

accelerating in 6th going 60km/h is nothing fun, a moeped has better acceleration.

yes, because you are bogging the engine, causing it to work harder to accelerate the car.

Post by **biggie** » Wed Apr 09, 2008 8:05 am

If its flat or downhill I'll hit 6th at 40mph or just below, usually from 4th. If going up hill I'll use 5th around 40-45mph.

Post by **Xtrykr** » Wed Apr 09, 2008 8:32 am

yeah, usually im in 5th, but b/c i live in winnipeg, manitoba, it is real flat here, it seems to hold fine on 6th at 60kph, its running at about 1700rpm?

Post by **rdsworks** » Wed Apr 09, 2008 8:39 am

Im in winnipeg too, so i know the feeling.

Post by **my_new_v** » Wed Apr 09, 2008 8:51 am

I normally drive on the freeway at 70mph and my rpms are normally at 3,100...at 75mph it sits around 3,600. What is 60km/h to mph lol. And at 40-45mph I stay in 5th gear. When Im in 6th gear, if the car drops below 50mph I go back to 5th because I can feel the car getting sluggish and can hear it working harder. Also when Im on the freeway going 70 in 6th gear, I have floored it a couple times and surprisingly it gets going pretty fast, never fealt it being sluggish or anything either.

Nothing different for me. Just thought I'd chime in with my $0.02 I actually posted a thread very similar to this...asking if it was normal. I wasn't sure because in my Z, which is a five speed (yes I know it's different) 70mph is much lower. But it is normal, nothing to worry about.

70mph=3100rpm APRX.

I use 6th gear if I'm on a flat road at around 40-45mph...but you would have no chance of getting up any sort of hill at all in a timely fashion in 6th at that speed.

MPH = KmPH75 = 12060 = 9650 = 8040 = 6530=4820 = 3210 =16

Post by **my_new_v** » Wed Apr 09, 2008 10:14 am

So 6th gear going around 35-38mph? Wow...how does the engine act?

absolute bullsh*t!

Nissan is jerking it's customers off with the inadequate 6 speed to sell the CVT which has the correct amount of overdrive for the car. I think the government should force them to provide a 6 speed that is as fuel efficient as the CVT.

well, i dont mind it being the way it is since i dont drive over 110km/h anyways. lol.

You go into 6th gear on flat ground at 45 mph and you're good to 60 tops where you need to shift again to a higher gear. You should be in a higher gear at 110km/h than you have.

The whole idea of a 6spd with 2 overdrive gears is that 6th is for cruising. It would have plenty of power to maintain 70 mph @ 2500 rpm. If you need more power for faster acceleration, just downshift.

The only issue with shifting @ lower rpm hurting fuel economy is when it causes you to use more throttle to achieve a desired acceleration rate. Generally if I'm in traffic where acceleration is slow to moderate I shift @ 2000. If the road is open I shift @ 3000.

Its just me but I always shift from 2800-3200 no matter where im at.

I shift at those rpms for 1st and 4th gears, but 5th and 6th, i feel, are almost identical gears :S

There is a definate difference in 5/6 but just not as much as there should be. At 65mph 5th is around 3700 rpms or so where 6th is closer to 3100 rpms.

Ah, okie, i haven't driven this thing hard at all as its still new. Question, when do u shift from 1->2?

If in a hurry at about 15mph, if driving slow anywhere from 7-10mph. The 1st gear is really short. Some I have heard will take it to 20+mph, but that's way up in the RPM range. I rarely go over 4500 rpms.

Post by **Xtrykr** » Fri Apr 11, 2008 6:05 am

Darn, thats pretty high, the highest i've revved the engine from 1st to 2nd is about 3500rpm. Anytime i start hearing the engine whimper, i shift, lol.

Same here lol

I hate how the V's gears are so small/short X(

i agree with everyone here. The gearing is all way off, and i know its because nissan wanted to make it feel more peppier with the slow 1.8 in it, but all it does is pisses me off on the high way. Even on local roads 1st gear is prob the worst, 1/2 the time ill just start in 2nd gear (if some what still rolling). And ive noticed that the flywheel is too heavy, i can usually get the syncros to line up when shifting, its just the wait of the rpms to drop to properly shift. It doesnt help that its a gear box type shifter either. If nissan continues with the 6 speed, i hope they completely redesign it because the motor might get decent mileage (somewhat...) but the trannys gearing is just hurting everything else. if only the 6th gear were longer, because im usually at almost 4000 at 80. the cars a pig, and handles like garbage (not to mention i already hear poping parts in the front...wtf). I wonder if the Tiidas 6 speed (if there is one) has the same ratios, cause what the hell was nissan thinking...)
