Looking at Toyota Canada's web site, I noticed that the Camry with the same 2.4/Auto as the Corolla's, has an advantage in fuel economy on the highway. Why? Shouldn't it be the other way around as the Corolla is smaller and lighter than the Camry?

just a little guess on my part, the motor might be the same, but that doesnt mean it is using the same tranny, or gear ratios. because the camry is a bit bigger and heavier, they probably do have some slightly different gear ratios.

on top of that aerodynamics effect the gas mileage on any vehicle. the camry could have better aerodynamics, contributing to better mileage.

finally, the mileage that you see posted is almost always an EPA estimate on any given vehicle. that means you are not guaranteed to get that good, but you could potentially do better or worse than what is listed.

RPMs at 70 with Matrix???

So, what are the gear ratios on the Matrix compared to Camry and Corolla?

I notice that the Matrix with the 1.8 and 4 speed automatic gets 32 on the highway vs 35 for a Corolla. I doubt weight would make that big of a difference on the highway when they both get the same city mileage of 26.

Does anyone know how much higher a Matrix automatic revs at 70 MPH than a Corolla?
A Corolla LE seems to do about 2800 RPM at 70 MPH.

I wonder how much different the Matrix is?

ITS AIR DRAG plain and simple...a camry can get better mileage because of the lower coefficient of drag and lower roof height...same as why ALL SUVs suck for mileage....

I checked my rpm the other day at 70mph it was right at 3000 rpms in 5th gear manual tranny.

I just got my base model automatic Matrix last week, and I was disappointed to get a measly 23mpg on my first tank, despite doing a lot of highway driving. I hope that improves over time.

That's odd, I have a base model 1.8l manual and did 328 miles on the first tanks which comes out to just under 32mpg all local driving.

automatic transmission takes more power, and thus will decrease fuel economy. i have the XRS with 6 speed manual, and i was getting worse mileage when i was driving 60 miles each way for work that was almost exclusively freeway about 70-75 mph (~27mpg) as compared to my current 13 miles each way which is more in town (~30). not much of a difference, but gear ratios do make that difference.

jdhog, if you drive on the freeway and keep your RPMs up around 3500, your mileage will likely suffer.

libmanj, if it isnt the XRS, make sure you only put in 87 octane gas. anything more than that is just wasting money, because the motor in the base and XR models is designed for the lower octane gas. this could also crap on your mileage a little as well. only the XRS is designed specifically for 91+ octane. that is part of being high compression.

Highway gas mileage is highly dependant on the car's drag coefficient (Cd). On the highway, the fuel burned is mainly used to push the car through the air. Air resistance grows exponentially (to the power of two) in regards to car velocity
09 Matrix Cd: 0.33
09 Camry Cd: 0.28
08 Prius Cd: 0.27

City gas mileage is highly dependant on the car's weight. At low speeds, air isn't the biggest effort the engine has to overcome. Pushing the car's weight forward and making it gain kinetic energy is the majority of the engine's effort in city circumstances.

As an update, I got 25 mpg on my second tank, up from 23. If the car can make it up to 27-28, I'd be pretty satisfied.I should also add that I live in Arizona and already need the air conditioner even this early in the season. I've heard AC cuts into fuel economy.

Brand new 09 with the 2.4L and on my first two tanks I got 26.5 MPG. It is more city driving than highway. I am pleased with it.

AC will definitely cut in on the gas mileage. the power for the AC is run by the motor, so it leaves less power from the motor to drive the car. the car needs a certain amount of power to go, so it will have to work harder to achieve that same driveability, which translates out to lower fuel economy.

That sounds a whole lot better than the Gen 2's. I would swear the 05 XR AWD i used to have got about 16 mpg in town. Of course thats driving on a military post, speeds rarely exceed 40, and dividing ~170 miles per tank, by 11 gallons of gas. (the tank is 11.9 gallons)

i used to work at boeing, and our group had a company car. it was a ford focus wagon with an automatic. speed limit inside boeing is 15 mph. we occasionally took it to one of the out buildings and got it up to 45 mph on the city street, but that was only for about 1 minute. that regularly got 150 miles on a tank of gas which was about the same size, maybe a bit larger, although i dont remember because i didnt fill it up much and i havent been there for 2 years now.

I too am on my first tank of gas in my new AWD Matrix.. combination of highway and city driving, and have only driven 250km (about 155 miles), and yet the gas tank is just over 1/4 left. What the hell?!?!
It seemed to suck up almost a quarter tank today on my way to work and back.. thats only 24km (about 15 miles)

Anyone else experience the same thing?

I wouldn't judge anything by the first tank of a brand new car. However, the window sticker shows the mileage isn't going to be all the great even after it's broken in.
Gas mileage is the main reason I haven't bothered to test drive it even though it otherwise might be a practical vehicle.

It probably needs an additional overdrive top gear for the highway.
