View Full Version : Quick question

Hi, I'm new to these forums and I had a question about my 2012 Yaris SE.

This car is a 5-speed and i learned how to drive stick on it (I know, not too smart with a brand new car) but since I'm still new to driving stick I was wondering what RPM to shift at for the best MPG? I've seen people getting 36+ and I am stuck at 32 MPG. I Shift anywhere from 2500-3000 at every gear. I must be doing something wrong.

If anyone could help me I would greatly appreciate it!

It also depends on the terrain, ie. going up hill more than downhill, etc. I shift between 4-5000 from 1st to 2nd, 3-4000 from 2nd to 3rd, and 2500-3000 for other gear changes and I get an average of 7.5L/100km, which is around 32mpg. I get up to speed quickly and then it's just sitting at the same speed in 4th or 5th gear for a lot of the time. Don't forget to use the engine for braking when going downhill by putting it into a lower gear, instead of using the brakes. The instantaneous fuel consuption drops to zero in this situation.

First, I don't have a Yaris manual, but I have had sticks in the past. I would recommend skipping second and fourth gears in your climb up the gears. Also, use the sound of the engine to guide you. You will develop an understanding of what the engine sound will be when you shift.

Hey I just learned stick too! I shift around 2200

There are so many variables that can/will affect your MPG. Shifting at a certain RPM helps, but only if you know where it will land on the power curve in the next gear. E.g. upshifting into second and landing on 2k RPMs while trying to corner or merge means that even if you mash the pedal, you're not going to get much acceleration.

The prevailing wisdom gets a bit muddled with the Yaris too: "stay under 3k rpm" and "peak fuel economy is at the peak torque output" are mutually exclusive for us. The stock motor makes peak torque around 4k.

That said, fuel economy is overrated. =P I've decided to make it more fun by shifting when I can land on the "sweet spot" of the power curve. Having an '09 without a tach means that I had to calculate the RPMs based on gear ratios and speed, but being able to get-up-and-go from almost any speed is way more satisfying (though juvenile) for me.
