BEHIND THE NAME.​

Mercedes-Benz racing cars became known as Silver Arrows as far back as 1934. Like so much folklore this famous nickname came about by accident. Back in the days when British racing cars were green, Italian red, and French Blue, the national racing colour of Germany was white. (Howard are you reading this) When the new W25s appeared for their debut [designed by Dr Hans Nibel -- twin cam, supercharged, straight 8, 4 litre, 420 bhp] in the Nurburg-ring paddock before the Eifel Grand Prix, that was indeed the colour of their paintwork. The celebrated Mercedes team manager Alfred Neubauer, presented the brand new cars for their pre-race technical inspection- and was gratified when they were one kilo under the 750 kilogramme maximum weight limit in operation at that time. The story goes that, for some reason, the precision of the Mercedes engineers attracted the suspicion of the Scuderia Ferrari team manager, Nello Ugolini, who was responsible for the factory Alfa Romeos. ( Nothing changes in Formula One really) Watching the W25s going through scrutineering, Ugolini, on an impulse, put his hand inside the cockpit of one of the cars, and pressed down on the brake pedal. There was no resistance: the pedal went straight to the floor……..
Ugolini immediately protested that the inspectors should examine the fluid levels in all the white cars. And his suspicions turned out to be justified.
Neubauer and his crew had no alternative but to top up the fluids and present the cars to the scrutineers once again. This time they weighed in at 752 kilogrammes…….
The W25 cars had been meticulously constructed to meet the weight requirements, and consequently there was nothing that could be removed to save the offending weight.
At the scene Hermann Lang was the chief mechanic on Luigi Fagioli’s car. He can recall the circumstances, although he can’t remember who suggested the solution: remove the paint, exposing the bare metal beneath it. “It could well have come from one of the mechanics because we were all standing around discussing what could be done about the problem,” Lang says. “The cars had been painted very carefully, in order to get an excellent finish, but the bodies were uneven, hand-beaten aluminium. This mean a lot of lead filler had been applied before the paint was sprayed on. And it was probably that, rather than the paint itself which caused the difficulty.”
After the white paint was removed, the cars were given a light coating of silver aluminium paint, and when they were weighed for a third time they were just under the limit, Soon after, it was an unknown press reporter who began to call the cars SILVER ARROWS.

This an extract from a Mercedes publication “The year of the Silver Arrows” to celebrate their success in the FIA World-Sports-Prototype Championships of 1989-90 editor Quentin Spurring.

Hope anyone who didn’t know this story behind Mercedes racing colours enjoyed it. Now you know why all those Mercedes are painted SILVER!!!

I suppose the old paints must have had oodles of lead?? ;)

NASA stopped painting the shuttle fuel tank to save weight.
Paint is heavy stuff.

is that hang on saving or weight saving :D :devil:
 
Mein Gott!

Maybe the story was just "spin" from the Daimler Chrysler PR men.

Everything I have ever read always recites the story abot not painting the race car, solely to get it under the maximum weight. I am merely querying the one kilogram of paint being used on just the bodywork of the vehicle (a relatively small race car) I wonder if the author plucked that figure out of the air?

You supplied a great link and I for one appreciate the effort :bannana:

I can't believe I typed that. So much for spell check buttons.
 
I've got the flu!

Cheers John,
thanks for your kind words. You know me. I just couldn't resist having a dig at Mercedes poor paintwork record in the late 90,s.:eek: Glad that things seem to be improving now. :) I am suffering from a bad dose of flu at the moment so maybe that explains it.;)

Hi grober,
I think we are all to forgiving over the issue of corrosion. Mercedes-Benz have a huge problem which is going to cause terrible damage to their reputation.

I hope your flu soon gets better.

John
 
And yet the W124's go for 10 or 15 years before any rust appears ....... ;)

As opposed to 10 or 15 minutes nowadays .......
 
Howard, you might find that the quality of the steel that cars were made of in those day was a higher grade and coupled with fact that up until about the mid-90's the paints used were solvent based, whereas now the basecoats are water-based to cut voc's (volatile organic compounds).

This is to say that I haven't heard or read this anywhere, it's just a theory of mine.

Plus the paint is much thinner applied now, you will most probably find there is about, (or was when new) 110-130 microns on your car. Whereas on a new car you will only get 90-100 microns. It's all to do with cost-cutting rather than weight-saving.

And getting on the subject of the weight of paint, I know if you were to paint a Boeing 767 200er it takes about 4000 litres, which equates to almost 4 tonnes when dry. Thats why now they don't paint the wings and the underside of the fuselage, which is a saving of about 65-70% on paint costs alone, never mind fuel savings and increased payload.

Cheers, Bill.

Of course we all know the real reason why MB paint their cars silver is because they look best in that colour, I am not bias honest.

I guess you're talking about epoxy type paints there, which set by curing rather than by solvent loss? A kilogramme per litre when dry sounds unbelievably heavy otherwise!

But Boeing say painting the upper and lower half of fuselage and tail plus customer markings only adds 135.6 kg for a 767-300! If you double or treble that to include the wings it would still be an awful lot less than 4 tonnes?!

They are actually a mixture of both, well Acrylics actually, they have a Hardner & Solvent. An EHB Solid can be up to, on average 80% Solids, some, such as Sigma Coatings can be up to unbelievably 100% !!

And a litre of a HB Solid (white) weighs in at about 1.3 kilos. Making it 5.2 tonnes wet, then taking into consideration flash-off and susequent solvent loss of approx 25% leaves you with about 3900 kilos. As I said almost 4 tonnes.

Cheers, Bill.

All I know is, is that I had to do a quote (supply only) for AirZim about 11 years ago on a B737/200er. (that's why I mentioned that aircraft), and that was the spec they gave me, quantity-wise. And I believe they got the spec from Akzo-Nobel, (Sikkens) who are, (or were) the only approved supplier for Boeing. And that was for the whole aircraft.

They subsequently only painted the top fuselage & tail, and they actually sent it to Boeing eventually. Which I have to say I wasn't pleased about, I could have just about retired on the commission on that one!!!! The paint alone, without hardners & solvents was worth 1.2 Million Dollars (Zim) about £80,000.00 at the time.

I think modern Mercedes-Benz should all be a deep metallic gold or brown!! :rolleyes:

We would then simply have to polish the rust :)

Team Philips, the high speed catamaran was also unpainted to save weight. Shame it didn't stop it disintegrating on it's maiden voyage.
