You are in the Mazda Protege
What is this discussion about?
Mazda Protege5, Wagon
#4394 of 7874 Sedan and Protege5 Plant Locations...

Both the Protege sedan and Protege5 are built in the Hofu plant. Prior to September 2001, the sedans were built in the Ujina plant. The Ujina plant has been closed as part of Mazda's restructuring. There are two Hofu plants. They build nine models including the Protege, Protege5, Tribute, and Atenza (Mazda 6). The number one plant was built in 1982; the number two plant was built in 1993. January 25th of this year, Mazda celebrated its 5-millionth vehicle produced at the plants which was a Familia Sport 20, a suped-up version of the Protege5. Both the Ujina and Hofu plants are located in Hiroshima, which is why it says Hiroshima as the assembly location.

Wait a sec here....Hofu is quite a distance from Hiroshima. Not that I don't believe you Jerry, but it seems odd to call a plant the "Hofu plant" and have it located a few hundred (est.) kilometres away in Hiroshima.
Ujina by comparison is located very very close to Hiroshima
Anyway, I like your explanation and it sounds completely right. Maybe they use the Hiroshima name to distinguish between Hofu I and Hofu II.

According to the people at Protegetech.com, the manual mode will actually let you exceed the redline. They upshifted at the redline and the transmission didn't respond until 6700 rpm. So, with the manumatic, it looks like you have to shift 200 rpm before the redline to get the tranny to shift right at the redline. Interesting...

The Tiptronic feature in my VW does the same thing. It will let you overshoot redline by 200rpm. Maybe that "give" is designed into the computer or something.

It's not like the engine is going to blow if you exceed redline anyway. You just don't want to run the engine beyond redline for extended periods of time. Anyway, you'll probably just run into valve float up there.
Most cars can handle the occasional mis-shift like the 5->4 shift I did yesterday while trying to hit 5->6. The Miata whined like a baby up to 8k, but it bounced right back.

All of these "sport automatic" transmissions, i.e. DC Autostick, VW/Audi Tiptronic, etc. are really just toys. As long as you still have a torque converter, you still have an automatic transmission -- which is fine if that's what you want or need. None of these transmissions will give you the control of a manual with a clutch - they all intervene in the gear shifting process in some way. I have a friend with a new M3 equipped with the SMGII gearbox. This is a true auto-manual, with a computer operated clutch (no clutch pedal). Maybe I'm a fossil, but I still prefer that third pedal
#4401 of 7874 Thanks for all the responses

I basically just wanted to know whether the sport automatic mode allows full use of peak horsepower by at least getting between 6000 and 6300 RPM. Since it lets the driver beyond redline, this is good to know. However, the sweet spot would probably be between 6000 and 6300 RPM. That is, assuming of course, that the lag between shifts is instantaneous. Otherwise, one would be better off just using the automatic mode.

Purchase my Protege5 yesterday, silver with Sport automatic and leather interior. Invoice is $17000, S-plan price is $16998. And I also use the 2.9% APR financing.
The car is great. Better than the Matrix. (I can hear rattles in the glove box on the Matrix).
Thanks everyone on the board.

Isn't there a rev limiter on the automatic cars? In my 5-spd, the rev limiter kicks in as soon as the needle touches the 6,500rpm mark.
In actuality, shifting at redline is best for maximum performance in our vehicles. Remember, the gears act as torque multipliers. Let's say you shift at 5,500rpm in third gear to put the engine at 4,000rpm in fourth. Sure, you've put the engine at it's torque peak (for a brief second anyways), but what about torque to the wheels? Since the Protege's torque curve is so flat, you will never produce nearly as much torque in fourth gear than you can produce in third gear. The same goes for all gears... The lower gear will always produce more torque than is possible in a higher gear. Therefore, to be putting the maximum amount of power to the ground, shift at redline.
Wanna see a Protege torque curve? Injen Technology ran a dyno on my '99 ES sedan before and after they installed their cold air intake. I have the dyno scanned in on my website:
Believe it or not, my 1.8L puts more power to the ground than most 2.0L's we have seen dynos for. Over at the ProtegeClub forum, the technical gurus were actually not surprised...
