5th gear is overdrive:
- 1st = 3.615
- 2nd = 2.053
- 3rd = 1.370
- 4th= 1.031
- 5th = 0.837
- Reverse = 3.583
- Final gear ratio = 4.056

 

Then the final drive is too high. There is only 500 rpm difference between 4th and 5th.

But thanks for the numbers.

 

You should call Hyundai and let them know their engineers and designers are wrong. Maybe next time they will consult you first.

Actually, there is a 669-rpm difference.
60-mph in 4th gear = 3558 rpm
60-mph in 5th gear = 2889 rpm

Remember, this is a small displacement 4-cyl engine with limited torque. You don't want the rpms too low. Those engine make power and are more efficient at higher rpms.

 

I tried calling them but they only take calls from you apparently.....

 

I forgot about that. I'll call them on your behalf and make sure they take you calls from now on.

 

I've thought about calling them. My Festiva had a 1.3L motor with a 5 speed. 4th and 5th were both OD and the car ran great, easily getting 45 mpg. The gear ratios on the Accent's 5 speed transmission are way to close for the most efficient economy. There is plenty of torque multiplication on this car. I didn't buy this car for its quarter mile performance.

 

The last Festiva was in 1993 (it was called the Aspire after that). It had a curb weight of 1797-lbs and a 63-hp 1.3L engine rated at 35/42 mpg (source).

The 2008 Accent has a curb weight of 2467-lbs and a 110-hp 1.6L engine rated at 27/32-mpg (source).

The Accent is 670-lbs heavier than the Festiva. That's like driving your Festivia around with three extra 220-lbs guys. I'll bet you wouldn't get 45-mpg in your Festiva with all that extra weight. Plus, the Festiva had a better fuel economy rating to begin with.

 

I guess I'll continue with my plan of going to taller tires then.

 

Taller tires will throw your speedo and odometer off. They will both be inaccurate and therefor, you won't know the true mileage.

 

I know that. But if the degree of error is known then the actual mileage can be extrapolated.

Whast's the 14" tire width stock?
