You are in the Mazda3
What is this discussion about?

For those of you out there wondering about this vehicle, there was a prototype pic in road and track for the SEMA show. Its a hatchback, same powerplant as the Speed6, but most likley no AWD.
Are you sure about that? According to another site reporting about the car displayed at SEMA 2005 they made the statement below. In effect, this is a tricked out version of the regular Mazda3 by which Mazda is promoting its Mazdaspeed parts.
MAZDASPEED-accessorized MAZDA3 -- The already stylish MAZDA3 adds an aggressive front fascia and lower lip spoiler, customized front grille, side sill add-ons, rear under-skirt and lip spoiler and MS-TII aluminum wheels (18x7.5JJ) with diamond-cut carbon-fiber center caps and 225/45R18 Bridgestone tires. A sport shifter for shorter shifts, lightweight flywheel and sport clutch with increased clamp load and torque capacity help improve the performance of the MAZDA3.

And I am consistently getting EPA estimates for fuel economy in my 2005 hatch with auto (4-spd).
My short commute takes me on an urban highway for a bit so I get a good mix of city/highway driving. The only downside is that the FE is only 24/29 to begin with.
For Christmas I drove from Augusta, GA to see my mother in Monroe, LA. A 645 mile trip, 99% of which is on I-20. I drove extra-fast on my way out because I was late, but I drove a cruise-controlled 73 on the way back. And I got spot on 29 mpg.
That is the highest I've ever managed to get. I'm not particularly happy the highway mileage is so low, but at least I know I can get EPA estimates by driving reasonably.

interesting....its funny how contradicting websites and magazines are on the same topic!
#180 of 963 Mazda 3 final drive ratio
Jan 31, 2006 (9:05 pm)
Today I test drove several Mazda 3, one 2005 3i and two 3s sedans - 2005 & 2006, all auto.
Driving on flat freeway at 65 MPH,
2005 3i (17K) = 2500 RPM
2005 3s (30K) = 3000 RPM
2006 3s (1.3k)= ~2400 RPM
This led me to investigate final drive ratio for Mazda 3. Here are what I found:
2004-2006 Mazda 3i&s MT = 4.105 28/35,25-6/32
2004-2006 Mazda 3i AT = 3.683 26/34
2004-2005 Mazda 3s AT = 4.416 24/29
2006 Mazda 3s AT = 3.863 25/31
So for all MT regardless of year and model, the final drive has not changed and Highway MPGs remain unchanged.
However, the 2006 s final drive ratio is smaller than 2004-5, and this allows for a better fuel efficiency and this is reflected in 2+ better MPG. The 2006 s I test drive has sport AT with 5-speed.
To conclude, if you want fuel efficiency, go with 3i, both auto and manual are okay. The 3i auto with a low final drive ratio 3.683 is pretty good with fuel. If you want the 3s performance but want to save on gas, go with the 3s MT or 2006 3s with 5-speed AT.

As per your list, the fuel economy numbers for the 2006 hatchback (3s) automatic and manual are nearly identical.
Transmission: City / Highway
Manual: 25 to 26 / 32
Automatic: 25 / 31
What source are you using: EPA, manufacturer, car mag, other? It would be interesting to compare these with the real world numbers that drivers are citing in Edmunds.
According to Consumer Reports, the EPA numbers are usually very optimistic, up to 30% more than what many drivers get in real world driving.

It is from 06 Mazda 3 brochure that I got from local Mazda dealer. It lists 2006 3s 26/32 MT, 25/31 AT. The 04 brochure that I got 2 years ago lists the 2004 3s 25/32 MT, 24/29 AT.

According to carlist.com, the drive ratio is the ratio of the gearset (usually the differential) that is farthest from the engine. A ratio of 3.54:1 means the driveshaft turns 3.54 times for every one turn of the wheels. Generally speaking, the higher the number, the better the vehicle's initial acceleration and pulling power. The lower the number, the better the vehicle's fuel economy.
Here are the numbers on the 2006 Mazda 3GTs from Mazda website:
5-Speed manual..................Sport Auto
Final Drive.....4.105...Final Drive......3.863
My question is, based on these values wouldn't you expect the automatic to get BETTER mpg than the MT (as well as more torque in 1st and 2nd)?

MT VS auto - final drive ratio.
Your logic is sound - the thing you are missing is - all automatic trannys have some degree of "slip" - which means some of the power that the engine generates gets lost - a manual has a direct mechanical link from the engine to the drive wheels - although there is still a small amount of slip in a manual - it is much less than an auto.
Look at it this way - If you have a manual in gear with the clutch out and stop the car the engine will die - an auto will keep running.
#185 of 963 Real life, really good mileage
Feb 02, 2006 (7:13 pm)
Just refilled last night: 448.0 miles elapsed, 11.61 gallons filling it until it wouldn't take any more. That is for a 2004 Mazdas3S MT with 27.5K miles, mainly highway driving. That is about what I normally get when driving on highway trips. Overall, the car usually averages about 35 mpg. Worst I have gotten with it in recent times has been 33mpg (stuck in stop & go traffic for about 75 miles).

I have 2005 Mazda3s Sedan 5 speed bought in may-2005 Build date march-2005. Right now it has 10,000 Miles and I am consistently getting 28-31 mpg in a 50/50 mix of city/highway traffic with my wife and 2 year son. I am neither a rough driver nor a smooth one
I never got an opportunity to go for a long highway ride but I expect the gas mileage to be nearly 32 mpg in that case.
So far absolutely no problem ( TouchWood !!! )
