Wondering why people complain that Yaris' cant get good mileage?!

I actually find that i get better mpg on hilly terrain, granted its still highway. Going down the hills i just throw it in neutral getting around 4-5 hundred mpg while maintaining speed (DFCO would slow my car, and i would again have to use gas, so neutral is better in this case).

There is one hill in particular that i drive all the time, 600 ft elevation gain and loss. From the start of my drive, the hill starts, 2.6 miles up, 3.5 miles back down, when i get to the top im at 24-25mpg, once im back at the bottom, im back to 44-45 mpg, then by the time im home, 13 miles later, im about 50-51mpg.

I think my car is magic...

Also, KrazyDawg, i notice you have an automatic, manuals are definitely easier to get better mileage with (which i have), and i baby mine.

Based on your gas log, you fill your tank quite often, what do you do that requires you to drive so many miles? I ask because i deliver pizza's and i do the same.

I have a 130 mile RT commute for work. On the weekends, I still commute a bit, so the Yaris never gets a break.

I've always suspected I get better MPG going up and down shallow mountain slopes than I would cruising at constant speed on flat ground. More energy is wasted turning the motor at cruising RPM than at idling RPM, so storing energy as elevation gain on the uphill climb and coasting or engine braking most of the way back down should yield higher MPG than cruising at high RPM on flat ground. Even despite the extra energy used to climb and the thinner air at higher elevations.

Just make absolutely sure that you're in a car that WILL NOT STALL while coasting. My stickshift Toyotas will idle happily until The End Of Time, but I've encountered some SUV type cars with automatic transmissions that will not idle reliably and are not safe to coast.
