@3000rpm

Not to contradict, but clarify, "most petrol engines are there best at 3000 rpm".

Diesel engines prefer 2000 rpm for best economy. Which is 75 mph and 44 mpg on mine.

I didn't say it was for best economy, it's the best economy/speed compromise. I get better economy at 2000 rpm but I'm not going anywhere with those revs . I know diesels tend to rev lower and have power in different places across the range so I suppose I was only referring to petrol engines with that statement, I don't know much about petrol engines or diesel engines so I will have to assume you're right . If I bust 3000 rpm my car drinks fuel twice as fast anyway, 80mph == not bad fuel economy 81mph == no fuel economy!

And a C200 is doing about 67mph at 3,000rpm ???

Is that a 2.3 190E ?

Might depend on whether you have a 4 speed or 5 speed gearbox.

Checked out the 3000rpm speed at 96mph indicated. Got 28mpg on a run from the east coast to Bristol, tho' not at that speed!

C200 Kompressor (Twin pulse) auto.

3000 = 83

 

[amdxp]

Okay, I got my answer, the 190E is a 5 speed manual .....

Well, I post another questionm that is ---

say to MOD my C180, is it better to go for Kleemann Supercharged or change to (used) C220 engine ?

I think from what I've checked, the C220 could be cheaper in cost. Also what about the fuel consumption ?

 

[Fudger]

Just tried this out.

3000 = 95mph.

Petrol not diesel though!

 

[markovich]

3000 rpm on old bessie is 68 mph 4sp auto

6500 rpm in 3rd 95 mph still going well

6500 rpm in top according to my speedo 135 mph ?

dont know if its true but its sure fast for a old timer

 

[smartbrabus]

3000rpm in 6th = 70mph

6th is quite tall for a 599cc engine...

 

[Kinky]

I'm with Markovich on this one ....

68mph @ 3000rpm with a 4sp auto.

My`02 C220cdi manual just hit a ton @ 3000rpm.

 

[PJH]

280E [4] 3,000rpm = 74mph
Older cars (like mine) have got dots on the speedo . .. ... to indicate max speeds in lower gears, so no need to red line it yourselves. (But it's fun)

 

[frog1520]

More data:

C180 (W202 manual) 70mph @ 3000 rpm in 5th
S320 (W140 auto) 85mph @ 3000 rpm

6500 rpm in top according to my speedo 135 mph ?

you will find that it may not reach 6500rpm in top
it might peak at say 5000rpm as the engine isn't powerful enough to reach that rpm in it's top gear. (or at least I think that's the theory behind it)

I couldn't quite get my C230K to max rpm in 5th, it was only a few hundred off though.

What speed were you doing at that point Graham ?

 

[GrahamC230K]

What speed were you doing at that point Graham ?

About 146mph indicated by the speedo, and saw 143mph on the GPS.

Suitable stretch of Autobahn of course. I was actually catching traffic up rapidly, but had to keep my foot planted as I had been cruising as high as 120-130 for numerous stretches, but oppertunites to totally max out were not too frequent. I guess I wasn't aided by the weight of my brother and I and a literally full boot including two spare wheels!

3000rpm = 135mph........in the Lotus

 

[uumode]

3000rpm = 135mph........in the Lotus

Now that is massively impressive.
WOW
