What you are experiencing is pretty normal for any car once you are in the top gear. 5th gear in this case has to be pretty long to be usable between 80 and 180 kmh. I had this with the 2.4l mustang I had in High school and my Sidekick. Normally on a Manual, you just do a quick downshift and go.
The "hesitation" your experiencing isn't, it's just then engine trying to cope with all the extra fuel you're dumping into it (remember it's not a V8)

You need lots of torque to pull 5th gear at 2,000 rpm. Your engine might not be up to that. At 40 mph I'd definitely downshift to 4th if you need a burst of power. 5th gear is really a freeway speed gear.

Let me jump in and ask, what is the optimal speed/rpm for highway fuel efficiency in the 5? Not quite on topic i know, but the two of you who responed to whobodym seem like people who might know.
Thanks,

Probably you should ask a longterm owner that question. Anybody???

I have an automatic. I notice the hesitation when accelerating from 100km\h (2900RPM) to 120 km\h. It lasts about a second, then all of a sudden after that second of hesitation, it just goes. I have read in other forums, that others are experiencing this hesitation especially in the 2.3L . I have notice the acceleration is not as smooth as my 1991 Toyota Corrola 1.6L.

I understand what you're saying but when this happens, our Mazda5 is definitely not behaving like a well set-up engine/manual trans combo. At steady part-throttle, the engine will have been pulling acceptably, producing some torque. The quick application of heavy throttle causes a one-second (or less) complete disappearance of any torque, like how an old junker engine with burned valves will backfire thru the carburetor at wide open throttle. A car should offer smooth, proportional torque that varies with throttle opening. None of my previous manual trans cars, at least one continuously owned since 1977, have done this -- Rabbit / Scirocco / Jetta / Accord / two Civics / Integra GS-R. Yes I understand about downshifting for power and accelation -- but this is another kind of driving. I should be able to get smooth response when I want the engine's best at 2000 rpm, just like at 4000 rpm or 6000 rpm.

My Mazda 5 is an automatic and I notice the acceleration is not as responsive or smooth. I have this hesitation especially a hard throttle like merging on to a highway or passing another vehicle on a single lane highway. This hesitation usually occurs at about 2900-3000 rpm when going from 90kmh to 110kmh. I have read in other forums that the 2.3 L is running too lean on fuel. Anybody with an automatic that experience this.

My theory is that it has something to do with the electronic throttle control software and the lack of torque. I'm guessing that engineers programmed the software to make the throttle input gradual, so there isn't a sudden neck snapping downshift. I also think the lower torque of the 2.3L engine coupled with the weight of the 5 compounds the problem.
I had a Mazda3 and now a Mazda5 (both with the 2.3L and automatic) and both hesitated for just a second when I floor the throttle at speed. However, the sensation is more pronounce in the 5 than it was in the 3. I attribute that the extra weight of the 5 and the lower torque rating of the 5 vs the 3.

Having a problem with your transmission? Or maybe you just have a question. This is the place to discuss it.
