I'm having trouble understanding what you want to know. I get that english
is not your first language, and that's okay. But you have to ask your
If the car has a clutch, then it has a 5spd transmission. 5th gear is a
direct drive 1:1 ratio, not overdrive. It will do 70 mph (115 kph) @ about
3,000 rpm. It will hold this setting for hours on end if you want it to. In
my car, the speedo and the tach both point straight up at about 85 mph (140
kph) and a little over 3500 rpm.
sorry for my english
i can try to do an example
in my fiat punto 1200 cc the top speed is in 4th
in 5th you can economize fuel.
in my current e30 318i top speed is in 5th gear
i know in 328ci e46 top speed was in 4th as the fiat punto
i won't buy a car who has the top speed in 4th gear.
i hope it's most clear
excuse me again and thank you
Top Speed on my E36 is 128 mph, but I can't say that it comes in 4th or 5th.
I always assumed it was in 5th, but your question makes me wonder if 4th can
go that fast too, of if Top Speed comes in 4th, and 5th can't go that fast.
Thinking logically, 4th would get to Red Line before it gets to Top Speed,
but I can't answer your question with facts. Sorry.
What I do know is that 5th is not an overdrive gear, it is direct drive (1:1
ratio). Most -- but not BMWs -- transmissions have 4th as 1:1, and 5th is
something in the range of 0.80:1 - which is overdrive. My logic says that
overdrive would cause speed loss at top speed, and if this is true, then BMW
should give Top Speed in the 5th on a 5-spd transmission.
The gearing ratio mostly affects acceleration, not top speed. A 5th gear
overdrive will still allow you to reach a faster speed than is possible in
4th, but the acceleration will not be as swift. The overdrive simply allows
you to drive at a faster speed at more comfortable, lower revs.
thank you for your interesting.
i can try to do another example
with the punto i have 90kph and the rpm counter at the same inclination of
the tachymetre ex. 3000rpm
when io put the 5th at 90 kph the rpm counter comes down to 2000rpm
i've seen the reviews of 328ci e46 and 530i e60 and both cars has this
behavior the 328 in 5th and the 530 in 6th.
now i found the review of 530 i
.....V 1.000:1- VI 0.851:1
top speed in each gear .... V 246.7 kpm - VI 238.3 kph
now the 323ci has V 1.000:1 i'm ok
