6MT Fuel economy Poll

With the first 10 votes in on each poll the CVT is averaging 3 MPG better thanr the 6MT:
40 to 37 MPG
Both averages are exactly 3 MPG better than their EPA combined estimates.

After over 100 votes in the 6MT poll the median fuel economy is 38.4 mpg
After over 75 votes in the CVT poll the median is 39.5 mpg

So it looks like the real world difference between the 6MT and the CVT is 1.1 mpg not the 3 mpg difference measured by the EPA test results.

Makes sense to me.. I have never driven automatics as hard as I do manuals.

The winter has dropped my MPG a few places from 36ish to 33.2 for my latest tank

I am getting 45 mpg per tank consistently.

If your fuel economy is 43 highway and 35-37 city, how can your average be more than 42?

Wouldn't your 3 tank average be around 39-40?

With 40 votes in this poll, the average for 6MT equipped cars is 38.0 mpg(US)
And With 22 votes on the other poll, the average for CVT equipped cars is now 38.5 mpg (US).
So the difference between the transmission types has narrowed to 0.5 mpg.

Wow. That's certainly unexpected. Anecdotally I only hear of the CVT CR-Zs consistently breaking the 50mpg barrier.

Another thing is that as the engine is breaking in and we're learning how to drive it optimally, everyones mpgs will be increasing over time. But there will be a drop as mentioned for respondents during the winter months.

I've not voted yet, my mpg is not very stable (more like increasing constantly by 1mpg per tank)

All this has been in winter weather so far, the last couple of tanks with snow on the roads.

Voted, average (UK) MPG is about 49, tho on a recent trip just this week over 380 miles for the round trip we averaged 52.8 UKMPG & still had some left in the tank....
Mind you, I went to fill her up this morning & it was £1.25 per litre at the pump and am now awaiting my dear husband to moan about the cost from Tuesday when the VAT goes up to 20% & thus shoves fuel up by another 2p per litre, he was moaning enough today at the extra duty of 0.75p coming in on fuel, so gawd knows what he'll be like on Tuesday.

Having filled to the brim all vehicles this morning, I got £25 in the smart (had just over 1/3 of a tank in it, the Z had £39, then took the van out & poured & poured, till it stopped at £100 (this wasn't on the red either!) not a cheap day in our house......

Mine dropped from 41-43 down to 37-39 as soon as it stated to get cold out too.....and I don't warm up my car or run the fan on high or the heat wide open--(so my autostop still kicks in). Explanations anyone?

cold weather = denser air, more fuel mixed in to compensate.

also engine takes longer to get to operating temp and uses more fuel doing so.

lastly winter mix gasoline has an effect.

I get 31 MPG city and hiway, But on the hiway i usually drive 72-75 MPH

Just got 45 MPG in 2 days of putting around Los Angeles for the holiday. Total mileage was 130 miles. Went from near Pasadena to Palos Verdes, across the peninsula to Hermosa beach. Next day up to Malibu and then up the canyon and home.

Most of the time I was in ECON, only pissed off about 10 people behind me the whole time. Went to Sport up through the canyon. All in all I was suprised how easy it was to maintain the high mileage. The car carried 2 persons and luggage.

Not a lot of driving over two days but got me from beach to beach. K

Could that be due to the tires having lower pressure in them due to cold temperatures? Maybe more rolling resistance is causing it, like more contact patch.

I know a LOT of people that never check their tire pressure...EVER!

I've been trying to get high MPG, so have been checking every month or so. I upped them to 38psi in the fall. I checked them a couple of week ago when it was cold and they were at 36psi. I'm sure that plays a small part, but not entire.

I've noticed about a 5 or 6 mpg difference between below freezing temps, and above 50 temps.

Over nearly 8500 miles my trip B indicates 37.4 MPG. Trip B has never been reset on my car.
