Drivers who speed when their car haven run in

mostly wat spd at wat rpm all depends on the gear ratios, a high gear ratio mean better acceleration which means a high rpm but low top spd, and vice versa(o...

What are the consequences?I saw a few whom i assume that their car have not run in yet cos it's new from the car plate i saw.

casshern SG

speeding is okay but u cannot rev ur engine beyond 3k RPM.

but wat's ur defination of speeding anway? if you light footed u can hit 100km/h in about 2200 RPM

scotts07 SG

but i thought on the day when i bought my car,the SE told me that we cannot exceed 80km/h?regardless the rpm.

kentheman SG

read ur manual..some car goes by speed, some car goes by rpm…

alberteinstein SG

manual zoon anot? my manual say anyhow ride, as long as dun push the engine too hard and also dun drive at the same gear same speed for extended time.
nvr talk about rpm and speed. i tot engine nature all is the same, so should use rpm best gauge. 80km/h is just that normal car, 6th gear at 3k rpm should give you about 80km/h. Please correct me if i m wrong.

For normal cars, I think 5th gear at 2-2.5k rpm will give 80km/h at steady speed already.

the best way to clock the first 1000km or ard that is to go KL and drive ard to shop and relax…then when u abt to go back u should have clocked 1000km already…

Lambo SG

haha later happily drive ur brand new car there come back window kena smashed n rims kn stolen i laugh Laughing u know those pple Mad

wbucket SG

Wah!!! Shocked Didn't know new rio have 6 gear? These spec sounds like Mazda6. Usually normal cars, 5th gear 3krpm would be about 100km/h.

zerocool85 SG

hmm..

i got post thread b4.. about how many rpm @ 100km/h

my old camry 5spd auto.. 100km/h @ 2000rpm
my new mazda6 4spd auto 100km/h @ 2700-2800rpm

i think 5 speed cars.. 3krpm will be 140km/h already ba.. i think also depend on car's capacity

alberteinstein SG

my mistake. 5th gear max in my rio. u ppl rite, 5th gear at 2k is abt 80km/h. 3k rpm give abt 100km/h. what car gives 140km/h at 3k rpm?? Shocked

alberteinstein SG

my friend also looking for a new car. I just got mine without much knowledge, so got a rio(like the design and price). So after getting it, got some thoughts about it. The max torque say at 4700rpm. does this mean that the car is most efficient at 4700rpm(efficient as in least waste of energy)? So am i rite to say a car with low max torque(like jazz at 2700rpm) is more fc friendly than a car with higher max torque rpm? then what about power?

eh camry got 5 spd auto meh? be it old model or current model i thought it has always been a 4 spd auto Rolling Eyes

Another cannot make it SE...

The rpm is more important in engine internal wear, not speed... speed will affect other parts like axles, tyres etc..

If he say 80 kmh max, disregard the rpm, then why not u drag 1st gear till 80 and just drive on first gear at redline lor.

Anyway saw one article on the web (dunno if true) that engine should be rammed early on (first 20 km) for piston ring to sit properly. This fella claim that if you baby the engine, the piston ring won't seal completely and you will have poorer performance/FC and more leaks.

Theoretically, it makes some sense, but not sure if its proven.

ceecookie SG

tried and tested...we did it with our car when it was very new....on the way to KL we just maintain 100-120km/h...then we relax there and shop...then when it was time to go back...the car had already clocked abt 1000km/h...so we speeded back....heh heh..did 170km/h....total mileage was ard 1500km/h together.....the serviced the car....

park at safe place and carparks to prevent thief....

zerocool85 SG

my old camry leh.. really...

3k rpm 140
4k rpm 160
5k rpm 180
5.5-6 215-220..

and my old model is 5 speed leh.. i got count the shifts...

zgim80 SG

So jus how much would it affect FC(or anything else) if a car is run in the 'baby method'? or has anyone tried reving e car hard for e 1st few times?

seow SG

Can rev, but must be slow and steady.

ditzy SG

Shiok hor, the new mazda6 got 6 gears. I also like it. Laughing

AF1 SG

camry 2.2? that's really weird.. if ur old camry does have 5 spds then how come the present camry only 4 spd? a case of technological degeneration Rolling Eyes from what i observe, the situation might be when u hit the 4th gear, after a sec or two when the car has a constant rate of acceleration, the rpm will drop 500rpm or so thus moving into overdrive mode and that might lead you to think that the car has shifted to 5th gear. this is just pure observation when I drive.
