Another 500e

[Darrell]

Talbir,

I haven't really got an answer so I will let the two of you sort it out.

Try Drag Times or Zero To 60. The US are obsessed with 1/4 mile times so there's plenty of information if you look. Renntech 600E for example with 25% more power/torque posts a 13.5s 1/4 mile in a roadtest. Nitrous 500E with 100bhp boost does a little better with 13.2s. Maybe I expect a little more but even these times only just qualify for a lacing IMO.

If you think you're going to walk into a thread, describe the 500e as nothing great and label everyone who does as wearing rose-tinted specs, then be prepared to justify the label and have a technical debate...and give adequate responses to technical questions rather than non-defined numbers or marketing talk.

Again, technically, please explain how a heavier car, with a longer ratio diff and 22lb ft les torque can post same or better times for 1/4 mile or any other speed/distance ?

Peak torque. You think it defines the nature of an engine? You seem to have forgotten all about aerodynamic drag . The R129 roofline is some 100mm lower than a 500E - the reduced frontal area means even though the drag coefficient is slightly higher, it negates this by a significant margin. Simply the W124 has to work harder the faster it goes.

The 129 also came with a 4-speed or 5-speed gearbox so they're not the same ratios.

Hmmn. Diploma in Aerospace Engineering, Degree in Applied Physics. I used to model vehicle dynamics as part of my job. Owned numerous V8s - three of them Mercedes. Am a Club Official for the MBOC. What exactly do you bring to the discussion apart from unfounded insults?

Funny, but I thought the W201 I still have was a Mercedes? Is ownership a requirement of the forum? If Talbir & I aren't taking this seriously then why are you when you've not made any contribution other than snide remarks?

Talbir, by all means organise something. I am quite happy to donate £100 to charity if a standard 500E laces* a 500SL or SL600 over a 1/4 mile run.

*please define lacing

[Gridlock]

I'm sure there's an Audi forum or 2 who'd be interested in your thoughts on the RS2

The 5 spd for the SL500 didn't come until after 1995 - when production of the 500e had ceased. During the time they were both in production, they both had a 4 spd box which had the same ratios. The only ratio that differed was that of the final drive diff.

Lace = beat....a win is a win is a lacing !

Aerodynamics doesn't come into play until above 70mph - recall previous posts, the discussion on times was 0-100kmh....for which the 500e will nicely lace the 500 and 600 sl.

[swannymere]

So, did we ever find out who has the biggest ****?

[maggot]

Who has.........or who is ? Perhaps a poll would be in order.

Well you're plain wrong on this. The 5-speed was a cost option on the R129.

Actually it's more like 50mph, either way it sounds like you're backing out of this faster than a politician at Question Time . When I stated the V12 was quicker in a straight line over 60mph you laid down the airfield challenge - so which is it?

Could you break a habit and post something of interest for once?

If you're not interested in this discussion - don't get involved .

[500E]

I don't mean to offend anyone, however can someone have arranged a stock 500E, SL500 and SL600 and have them booted from 0-whatever and just see the results?

Very interesting topic however!

[kth286]

yes - aerodynamics come into significance at 50 onwards.

And your helpful post`s are???Talking about ME and getting info from carfolio.
I`m not going to bother any more anyway.

I reached for my precious Technical data passenger cars (October 1993) again. Does anyone else have one of these official MB handbooks with 800 pages of definitive info (perhaps the WIS has replaced it)? Anyway, it says (two up, 4-speed autobox, CATted):

500E: 0-100 kph 6.1 seconds; max speed 250; rear axle ratio 2.82; weight 1700kg

500SL: 0-100 kph 6.5 seconds; max speed 250; rear axle ratio 2.65; weight 1800kg

My guess is that the SL's extra weight would tell against it until its better aerodynamics cut in, so it may well be faster over the quarter mile.

Now, I swear that my 300E twin turbo (1420kg) is distinctly faster than my SL500, and some claim that it is faster than a 500E (including someone who has owned both), but that's another story.

What's half a second between friends driving normally?

There is no 5 spd gearbox from MB that mates to the M119 engine - period ! MBUK will confirm this for you.

MB never offered a 5 spd gearbox on the SL500 / SL600 before 1995 - there is no MB auto 5 spd gearbox in the world that mates directly to an m119 engine.

The only 5spd gearbox cost option was for the SL300/320 - not for the pre-95 SL500 !

Is that so?

You seem to be forgetting that the M119 was fitted in the R129 500s until the '99 facelift - All Model Year '96 - '98 cars come with the 722.6 5 speed as standard .
