When is someone going to supply parts to correct Nissan's failure to install overdrive in their 6 speed manual trans? BINGO!mitchellhuth wrote:I drove a Honda minivan the other day and the engine was turning at 2100 rpms at 70 mph and the Versa turns 3100. This little 4 banger will wear out quicker at 1000 rpms more and use more fuel to boot!
The Versa is plenty capable of maintaining highway speeds at 2300-2500 rpms if it had the gearing. I would even be willing to have a 6th gear that was too tall and downshift for hills if necessary if it meant better gas mileage. To ad insult to injury, Nissan won't let us pull a trailer with this low gearing even though you can tow 2200 lbs with a tiida!If you're expecting a 4-cylinder with half that to keep a 2800lb car going at highway speeds at a lower rpm... the problem isn't the car - it is your expectations of low rpm.
hi gear is low engine rpms, low gear is high engine rpms.Andrews Chalmers wrote:Compensated largely by the variance in the driveshaft/differential connection.
In the CVT, the final drive axle ratio is 5.47:1
In the manual, the final drive axle ratio is 3.93:1.
The higher axle ratio, the engine would have to run at a higher rpm to maintain an equal cruising speed. The lower axle ratio, the engine would run at a lower rpm while maintaining the same speed.
Correcto on all counts.mitchellhuth wrote:The Versa is plenty capable of maintaining highway speeds at 2300-2500 rpms if it had the gearing.

you're too generous. It's a 5 speed with an extra gear to go through.xtwoonamatchx wrote: its more of a 5.5.
I don't think you understand the meaning of "final drive axle ratio." Engine rpm at any given speed isn't just a function of the gear ratio in the gear box, but you also have to consider the drive axle.boxcarbill wrote: hi gear is low engine rpms, low gear is high engine rpms.
I used to hot rod Chevys. The LOWER the rear the more rpms of the driveshaft to make one revolution of the wheels.
The stock 3.08 rear was replaced with a 4.10, 4.56, or 4.88 for quick starts out of the hole.
It's more like a four speed with two more gears!boxcarbill wrote: xtwoonamatchx wrote: its more of a 5.5.

My '07 hatch shows 2k rpm @ 44 on the speedometer in 6th gear. I get 35 mpg in the summer if I don't go over 55 mph, and that includes some stop and go traffic. On the freeway @ 3k rpm I get about 33 mpg. If I had enough overdrive that would probably increase to 35 mpg at the same speed (about 70mph actual)mitchellhuth wrote:It's more like a four speed with two more gears!
I noticed today that I can go about 40 in 4th gear at 2500 rpms. At 40 in 6th I'm turning 2000 or so. That ain't right. I usually skip 4th gear and go into 5th to cruise at 45 speed limits and skip 5th when merging onto the freeway.
But I will say I seem to get 30 mpg even when I go 75 mph.
(the kicker is my 10 year old chevy prism gets 35 mpg no matter how I drive!)
