anyone know the 6 speed gear ratios?

[boxcarbill]

I suspect the 6th gear ratio is only the standard 25% overdrive found on most vehicles.

also my Versa has a serious lag time delay in response on the accelerator. I haven't talked to a nissan tech yet but I sure hope it can be adjusted.

Welcome to the wonderful world of drive-by-wire throttle. You don't have an actual throttle cable that links directly to the throttle body, your input from your foot is calculated and then the throttle opened electronically by computer. there is a slight delay in any throttle change you make. It's also not unique to the V, other DBW cars Ive driven are like that and it drives me a little batty.

[Clipsed]

if you don't like the response on the V, you won't like it on a Mercedes either! The V8 I drove the other day lacked in repsonse worse than the V, and the steering was not as nice as the V as it is electronically dependent on the speed of the car.

thanks for the replies. looks like only about 12% difference between 5th & 6th gear, bummer. I already want to put oversize tires onto my stock alloy wheels to increase my overdrive potential. anyone ever try to get 205/70/15s on the little bugger?

The throttle DOES drive me nuts. Trying to learn to shift around it is crazy. I have to take my foot off the gas before I push in the clutch, then get on the gas again before the clutch is released. NUTSO.it also gives the engine gas if I am in a gear and the engine rpm is too low. Too bad I can't just get into the back seat and get driven to town by the little wonder.

man...i have no problem driving my car. I notice that part when the RPMs go low but as for shifting...no problems there.

There seems to be at least one full second or more for the engine to get the message my foot is off the gas. Maybe it's just a reprogram fix at the dealer.

I assume "Final gear 3.933" refers to the differential. In other words 3.933 revolutions of the transmission output shaft for every one revolution of the wheels.If so, according to my calculations the Versa 6 speed has 7 to 8% more overdrive than the Honda fit (depending on wether the fit has the factory 14" or 15" tires).If I can get the 205/70/15 tires to fit the Versa I'll gain an additional 8% overdrive giving approx 16% more overdrive than the Honda fit.

How are you goign to gain overdrive? The ratio is constant in the gearbox. You will be turning slightly less RPM at any given speed but you will not and can not GAIN overdrive without a gear ratio change.

[07blueversa]

I dnt have any probs driving my 6 speed. I drive it as smooth as an AT. Mayb u just gotta get used to it?

[Ever Victorious]

If you increase the overall diameter of the tire, you increase the distance the vehicle travels during one wheel revolution.

Check out what happens when you change the aspect ratio of a tire... making it thinner or thicker overall.

[boxcarbill]

totally false my good man. by increasing tire diameter you gain overdrive. less engine rpm to travel at higher velocity.

[boxcarbill]

it's goin into the service dept Monday...I got my fingers crossed. Do you get off the gas pedal BEFORE you push in the clutch? I have to with mine.

The gear ratios are often found in the owner's manual.I found these gear ratios on a dealers website:http://www.courtesyparts.com/versa/specs.htmlUnless the 6-speed ratios change for 2008, it's NOT a wide ratio

2007 Nissan Versa 6-speed manual transmission

6th gear overdrive 0.81drive axle gear ratio 3.93185/65-15 tire 824 revs per mile

crankshaft revs/mile = rpm at 60 mph = 0.81 * 3.93 * 824 = 2627 rpm

2007 Nissan Versa cvt transmission

cvt high 0.427drive axle gear ratio 5.473185/65-15 tire 824 revs per mile

crankshaft revs/mile = rpm at 60 mph = 0.427 * 5.473 * 824 = 1926 rpm

it's hard to believe such a vast difference between the 6 speed and the cvt in overdrive. those rats are dumbing down the 6 speed in favor of the cvt to sell more cvt's. the 6 speed is more of a novelty/gimmick than anything else. The closeness of the ratios at the sacrifice of praticality really sucks.

the brochure for the 2007 shows 34 mpg hwy for the 6 speed, 35 mpg for the auto, and 36 mpg for the cvt....now I know why. We'll sell you a 6 speed but we don't trust you to use it properly.

I agree the gears are way to close. 3 rd & 5th are rarely used. I wish the Versa at 65 mph was at 1500-2000 rpm and at 75 mph between 2500-2700. Then the V could be rated closer to 36-38 mpg. This engine has more than enough power to climb hills & mountain in 6th gear. I have yet to downshift to 5th on I-70 heading west out of Denver.

[motoguy128]

The gear ratios are a lot wider than on my motorcycle. 2nd-5th on my Versa are about the same range as 1-6 on my BMW.

I think if you compare the gear ratios on other 1.8L cars between 2500-2800lbs, you'll find that it's not unusually high. More noticeable is how close 5th and 6th gear are and how low 1st gear is, because most cars in it's class (other than in Europe) don't have 6 speeds.

The Honda Civic has a taller 5th than the Versa, but not by much. It's also much less responsive than the Versa because of it. The Civic makes 140HP, but at highway speeds the eingie doesn't make much more power than the Versa.

I wish automakers would publish the mph/1000 RPM of each gear, along with a 50-70 top gear accelration number to show the "real world" power of the motor and isn't affected on driver skill... and even better the engines power and torque curve.

I'm sure I'll be labeled as a newb ... but when you change Circumference of a tire you are changing the Final Drive Ratio of the gearbox effectively. You can not change the overall gear ratios. The ratio will always stay constant to the ratio of the FDR.

[motoguy128]

True, changing the tire diamter effectively changes the final drive ratio. If you increase the final drive, you will increase the effective ratios of all 6 gears and increase the spacing between them.

You will also make the car accelerate much slower due to the taller ratios and wider spacing, as well as the additional rotating mass of the wheels. Additonally the heavier wheels will make the suspension less reponsive over bumps and can cause addiotnal strain on the suspension system and drivetrain components.

[boxcarbill]

according to my calculations the Honda fit 5 speed has a lower first gear ratio overall than the Versa 6 speed.
