Yes, and for any 280 drivers here, if you've only ever driven it in "Drive", then put her in 'L' and really give it to her! You'd be pleasently surprised!

Had a lot of fun learning what this beauty of auto trans can do...
Played a lot with going in S or L at differnet speeds (not more than recommended for either of them ::))

When I bought my 280SE it reached 100 in about 14-15 sec (new it would have been 11)  ;D

But after finding my Merc Dok... he tuned it up... and latest test showed 0-100 km:
- on petrol: 9.8 seconds (eating 30 litres at 100km on that throtlle :o)
- on LPG: 14 seconds

That's a serious emprovement. Now it does it in 12 (but tuned for more economical driving 8))

Whoa  ;D

Thats nearly equal to a 350 to 450. :) nearly...

I have some road tests of the 280SE and they say for the 1973 model the 0-100kph is 9.7 seconds and the standing 1/4 mile is 17.3.
The polluted 280SE in 1977 did 0-100 kph in 12.3 secs.
The 1975 280S with carbie did it in 11.6.
I assume the 1973 280 had electronic injection and of course the 1977 one was mechanical, that's one reason the 1973 model was quicker. (Along with the lack of pollution gear.)

Also to Michel, I was told not to just "plant" the foot on takeoff as it puts lots of load on the drivetrain. (I do and it is "spectacular.)
If you load the drivetrain by applying the footbrake, accelerate slightly against the brakes, then at the same time as "dumping the brakes you "plant" the foot, this puts less strain on the drivetrain.

HaHa... yes it's much more impressive to "light up the tyres" at the traffic lights.
I did it often to wear out the old tyres. (They were crap.) Now that I have fitted new tyres, I haven't done it any more. The new tyres have too much grip and I don't want to blow up my diff. (And other associated bits.)

In my opinion, "S" stands for Sport in the 280  ;D

I'll remind you of that when I'm sitting on the side of the road with a "blown" diff, stripped flex plates, broken axles and worn down tyres!!
Let alone the slipping transmission!! .....  :o  ;D

I thought the "S" was for "Second". I could be wrong.

Andrew116

Mercedes states that S is for "Slope"  ::) . Well it sure acts like that on steep roads  ;D

yes, as the other Andrew said here, "S" stands for Slope.

I just said it stands for Sport because of the way it transforms the 280:
High revving (later gear changes), twin cams roaring and much more rapid acceleration  ;D

Hi guys, never mind what Michel says about smoking and spinning tyres-using MY technique, I recorded a 0-100 km/h time of 6.2 seconds. Plus, I have just carried out a fuel consumption test-137 kilometres of reasonably gentle Freeway cruising and 72 kilometres of suburban driving-used exactly 31 litres of 98 rating BP ultimate. My contribution, Styria

Styria, that is pretty good. I think your gleaming beauty must be well tuned and in excellent condition.

I reckon his "Gleaming Beauty" is really a 280SEL with 450SEL and 6.9 badges on the boot lid.
He has been conning us all this time!!!   ;D :D ;D

I timed my 6.9 on Saturday - 11.3 seconds. Thought it was a lot quicker and I'm quite disappointed. I know that the altitude may be factor (Pretoria 1333m above sea level) but surely something is very wrong?

Altitude aside, I reckon something is wrong there, Grant.

My (Euro spec) Dec '79 280SE pulls 100 km/h in 11 seconds (and so does my W108 280SE). (I live about 13 metres above sea level.)

That incredible economy Styria - I did manage 450kms off 75 litres last week - 16.6l/100km's; but your 14.8 is spectacular.
sigh....sitting back contemplating the next purchase..!

This time of year is South Africa hot as hell?

I only ask as I know friends who drag race in the Northern Territory of Australia say due to the hellish conditions you can add 2 seconds to your 1/4 time compared to somewhere normal in Australia, i.e. Melbourne.

I'm not a mechanical genius but I would be looking at your spark plugs, timing, engine compression, timing chain etc.. if you are still in doubt.
I know I get a serious dose of power and performance with my new timing chain

where your tyres squealing much?

I know with my 17"s now I have so much more grip, I can just boot the car and it just goes, no more squealing.

I might do a 0-100 and report back

QuoteIn the rain, i can do about 0 - 180km/h in about 3 seconds - well that's what the speedo says, the car isn't actually moving though 
And 180 to 0?  ;D
