Guys I really need to know this. Tell me what rpm you get when you go 65mph. Automatic user inputs would be helpful. thanks.

 

[chickmod]

dang, i wish i had a mazda3 to go check this on. i like your signature!

at 110km/h (roughly 65mph), the engine revs at about 3250ish 120km/h will bring it to about 3500.

I have a 3 5-door auto.

Interesting, for me, at 65 mph the RPM gauge reads 3000 when the overdrive takes over from 4th gear. Maybe the HB weighs more, so the engine has to work a little more?

??? As long as the hatch and the sedan have the same rear end and transmission, the cars will be at the same RPM at the same speed as long as they are in the same gear. Weight and how "hard the engine works" has nothing to do with it.

The rear in the Mazda3 is very aggressive, somthing like a 4.21. You should expect the revs to be fairly high at highway speed. Really nothing to worry about.

Then how to explain the rpm difference at the same travelling spd??

110 kph is actually 68.5 mph. It's not the same speed as 65 mph. Therefore, at 110 kph the rpm is slightly higher. Eipromb said roughly 65 mph, not exactly, and 3250ish, not exactly 3250. There's no difference to discuss.

Heh-heh... I'm usually at 65 by the start of third gear, but that's because I redline 1 and 2 in manual.

 

[br3ad-bOi]

LOL @ spence lol how often do u redline ur car

 

[DJ Spencer]

too often.

I like to zip to my destination - but then again, I only drive 4 miles to/from work.

 

[br3ad-bOi]

no worries i redline it a few times too
just to see how fast this car can go heh

 

[Inno]

Is it not good for the car that u redline it that early?
has ur car broke-in yet?

 

[rpc180]

I redline at least once or twice during mid-trip (approx 15-20miles) just to keep the engine in line. Coming up on 5000mi.

The 2.0 AT revs considrably lower than the 2.3 AFAICR.

b/c the 3s has a more aggressive rear end. All of the above examples are the 2.3.

Redlining your car is good for it.

Why do you think the autos have the tiptronic? SO THAT WE CAN RED LINE!!

 

[rsx_r04]

Why do you think the autos have the tiptronic? SO THAT WE CAN RED LINE!!

On the other hand, you can still red line any car with an automatic transmission. :wink:

Step 1: Put foot to floor.

Step 2: Leave it there at all times :twisted:

Yeah u can put to L or 1, or if u dun, then start from 2, redline then release to 3 or D3 or D(with overdrive button cancelled) for the 3rd gear
