Has anyone else heard about the 408 bhp M5 specials that were produced by Motorsport?

The story goes that the factory produced 2 or 3 cars (circa 1993 model) with breathed on motors for the likes of the touring car drivers and Paul Roesche.

I spoke to someone in Motorsport a few years back who confirmed this but would not divulge the specification or provide chassis no's.

Then a friend of mine who unfortunately is no longer with us heard that one of these cars was purchased by a wealthy guy who lived on the south coast and for enjoyment drove sight seeing coaches across Europe.

I tried to track him down but this came to nought, I even contacted the service departments of the main dealers in the area to see if this car had ever received servicing/repairs by them but this showed no result. It was said at the time that he used to have the car serviced in Munich but that seems a hell of a long way to go!

It would certainly be a nice power to weight ratio, I believe it was acheived by trick cams better breathing and a boyesen exhaust.

if any one is interested in a 4.0 liter block I have one. It has a 4.0 stamped on it. It comes with a statement from bmw that these have been produced but were supposed to be discarded and not taken home...
I had contact with one of the former engine guys from this time. He told me that around 100 blocks and 200 heads were produced but they never managed to get the heat problem solved for a "normal" street car.
Please contact me if you are interested.
I can ship worldwide.

Hi all.

Barely read the topic to the end. :)
Thank you for a lot of interesting information about this unicorn.

4.0 cylinder blocks were mentioned here. Several cars with this abbreviation got into Russia. All parts (block, pistons, crankshaft) were measured, they met 3.8 standards.

Wrote through an electronic translator, translation heresy is possible. :)

@magno - @fatih.aloglu -
A said, I agree these are interesting cars. However, there are
no indications or facts pointing towards the 400/408 bhp
subject cars. On the contrary, as these cars all
seem to be exhibition, photo, demo cars, it is unlikely that
there is any connection to the 400/408 bhp cars that were
,given, (except for the official Dubai car) to
BMW celebrities and ,/// M GmbH courtesy contacts’.

It also seems from the files that the a.m. cars had been
researched and investigated before. Again, fantastic vehicles
but no ,400/408 bhp cars‘ connection.
If you wish, I suggest we discuss these cars under a new
heading or in the pm/communication/message function.

As for GD64079 and just for the record > this car was
recently auctioned on BaT and subsequently moved from it’s previous owner in the U.K. to the US, to a new
owner and to join the considerable number of
E34 M5/M5touring cars ,over there’ already.

@M5Touringreg
I have a copy of an interesting dcoument that maybe you could look at for me relating to this car.
Could you let me have your email address as I cannot send a PM until I have got to 45 posts.
Many thanks

Have you studied all the 34 pages of this 'thread' incl the inputs made by Signore J.M. Graziadei ?
(btw > he is the owner of the E34 M5touring assembled/prepared at the Garching facilities of the M-GmbH for the 'Motorshow Bologna' in 1992(!)) -

I will have to get the engine number from the car when I am next back at the garage.

BMW grouparchiv confirms that BMW E34 M5 VIN GD64079 with
production date 25.10.1993 was released/delivered to BMW Italia spa
in Palazzolo/Verona on Nov. 15th, 1993.
Engine-/gearbox numbers will not be communicated, however, if
provided for, will be confirmed to match with the original numbers (or not).

From what I understand, the Dubai car had a special exhaust but that would not pass EU tests
so the 408bhp cars in europe ran the standard exhaust.
-
So GD64079 has the standard S38B38-engine exhaust system fitted ?
How about the engine-/gearbox-number ?? What is the present mileage ?
Also, a nice picture of the engine bay would be much appreciated to see.
 
#325 · (Edited)
GD64079 was built on 1993-10-25 as a -presentation vehicle- for the Motor Show Bologna’ 1993.
It is an 1994 modell year car (VIN GD64000 > GD64334) and thus NOT a modell year 1995 car.

Motor Show Memorial Attilio Bettega Bologna (ITA) 4/12 > 12/12/1993.
The Bologna Motor Show (known as the "Salone internazionale dell'auto e della moto di Bologna" in Italian) is an auto show
scheduled to be held annually in December, in Bologna, Italy.

The 1993 Formula One Indoor Trophy took place on December 4–5 at the Bologna Motor Show. The winner was Rubens Barrichello in a Jordan-Hart.

In Oct 1993 and until 06/94 the 5-speed gearbox and the brakes 315x28 VA, 300x20 HA were used in the assembly at the Garching facilities.
The 6-speed gearbox and the compound brakes package 345x32 VA, 328x20 HA became available as of 06/94 with the beginning of the
model year 95 assembly.
With the introduction of the modell year 1995 E34 M5 sedan/touring,
a face-lift package in accordance with the model year 1995 ‘face-lift’ specifications of the E34 M5 3.8 sedan/touring was offered by the M-GmbH
to all previous owners of an E34 M5 3.8. The price for the package was DEM 26.000 and the car had to be turned in to Garching for the
rebuilt. The rebuilt took appr. 2 weeks and an equially valued M-car was provided to the customer by the M GmbH during the waiting time.

The wide kidney front (as being used in the normal production for the E34 M60/V8-model cars) was available to all customers
as an extra-pay option already from the start of the production of E34 3.8 M5/M5touring.

Some pictures and comments (swedish):
M5Portal.com - M5 Individual utställningsbil - Bologna 1994

So far so good, it now remains to find proof if this car indeed is one of the few ‘rumoured’ (one confirmed) and
mysterious 400/408 bhp factory cars. There are indeed ‘signs’ in favour, the research continous.........

That's really interesting. Is there any documentation for which cars this was done on?
I'm curious for my touring, BL01676, the build sheet data does not list the M60 front end, but it has had it in every picture i've seen (prior to coming to the US). I know it is very likely it was just 'updated' at some point, but would be interesting to know if it was done at Garching.

Hi again.
Apparently I got a bit 'carried away and exited' last night :eek
I will now do some home-work, check the actual facts, my files and some archives and revert with my findings/thoughts.:nerd

Meanwhile, have you already checked the engine / gear box numbers ?
If so, what are they ?
 
#323 · (Edited)
-
Of course it was a 'special order car' built and prepared for the 'Bologna motorshow'. The built sheet shows it as well as the M60-V8-front option, no doubt.
-
Do you know, what was the date of the 'Bologna motorshow' for which this car was 'prepared' for??
Do you have confirmed information that this car was indeed fitted with the 6-speed-gearbox and the compound-brake-package AFTER the 'Bologna motorshow' ?
Do you have any connections/contacts with people who were involved in BMW motorsport-teams, racing in Italy in those days and
are located in the U.K.?? If so, you might find some answers there.

Hi

It could be a tuned version as it was supplied to Italy with a very high spec (probably the highest spec m5 if you look at the options list) at around the time that the alleged Gabanelli car was around. It was sent back to M to be upgraded with big brakes, 6 speed gearbox and diff. It is burgundy red colour which fits in with the description of one of the tuned cars.

I'm just trying to see who knows what about the car.

I haven't driven it hard yet as I need to check valve clearances and recomission the car after a long time in storage so can't comment on whether it's quicker than a standard m5.

Hi again.
A 'burgundy red coloured' car is indeed being referred to as being one
of the 'mysterious' 400/408 bhp cars. I happen to have some information to whom such a car was given
by the M-GmbH before it was sold on...... however, no VIN confirmation was ever given.

As for the high rate of specifications and options this is obviously not
unusual for a car prepared for an 'international motor show'.

If not a regular modell year 95 car already, the M60-front option note in the vehicle spec list seems to indicate it was NOT, then it
surely was a 'pre-series-95-modell-year' to be presented at the
'Bologna-motor-show' to introduce the E34 M5 3.8 'face-lift' 95 modell year car and as such it was very likely equipped with the
6-speed gearbox and the compound brakes BEFORE the Bologna motorshow.
Whatever, a VERY interesting find and perhaps........who knows.....
Good luck with your research.

No, I said the car had been stored for 10 years. Whether I owned the car or not during this time is surely irrelevant as to my enquiry as to if it may be a 400 bhp variant.

However, I own the car GD64079 and am trying to establish its history. It probably isn't one of the tuned versions, but, as it seems that some remain unaccounted for, it would be good to try to establish if this one is or isn't one of them.

Fair enough. My apologies for assuming this car runs in Sweden,
apparently I mixed it up with another 'motorshow' E34 M5, sorry.:wink
Congratulations to your ownership and good luck with the digging for
history details. However, what is it that makes you think it could be one the 'mysterious'
factory 400/408 bhp factory E34 M5 ??
-
I believe it went back to garching after the show where it was upgraded with the
factory large brakes and 6 speed box to add to the already massive spec.
What is it that makes you believe this car was 'upgraded' in the Garching facilities for some reason ??
Is GD64079 not a regular modell year 95 'face-lift' modell car ??
 
#315 · (Edited)
Does anyone have any information on the 1993 bologna motorshow car?

Could this be one of the 400 bhp cars? I believe it went back to garching after the show where it was upgraded with the factory large brakes and 6 speed box to add to the already massive spec.

The E34 M5 built-date 1993-10-25 for the Bologna motorshow (1994??), colour: 'Zyclamrot-met.' (FE 68-300A BASF) is running in
Sweden and NOT assumed to be one of the legendary factory 400/408 bhp cars.:frown

I am NOT a drag racer....but:
1000hp M5 - AT&T Yahoo Search Results
http://search.yahoo.com/yhs/search?p=1000hp+M5&ei=UTF-8&hspart=att&hsimp=yhs-att_001&type=sbc_dsl


It seems to me that the S38 is an extremely strong engine, and if you really want to create big numbers, you just need to blow in it, even at a fairly mild boost, maybe an easy centrifugal supercharger. (Old hat, but so's the car).

On the other hand, my abused but very greatly loved 180k mile stock engined S38B36 gets my heavy beast around VIR racetrack very damned well, and it can outrun many race spec BMW's, beats US spec E36 M3s, and even sticks with SOME stock E46 M3s, depending on tires and, well, driver, although I'm only counting instructors.

Yes, unfortunately, a freaking Subaru or Camaro beats it in a drag race, but hey, I don't drag race....;)


Wish I had a B38, though....... ~300whp would be nice.

BigDog, thanks for your message and clarification. I am browsing the different post sections and had posted a question as to the "desirability" or "collectability" of my Dinan prepped 540M-sport with that question being should I track the car or hang onto it. Both you and PorscheH6 have answered my question and those answers leave me with no questions in my mind. Cheers and see you at the track.
