A Story of the Silver Arrows …

I’ve recently corresponded with the Mercedes-Benz Museum Archives, and they very kindly sent me copies of their publication “Magical Moments – 120 Years of Motorsport”.



One of Mercedes-Benz early racing successes, the 1914 French Grand Prix.

There is a great cross-section of their motorsports successes from 1894 till now.


As I read through the publication, an interesting story was featured in relation to the 1934 Grand Prix season.


The AIACR, the controlling body of motor sport in the 1930s, introduced new rules for the 1934-37 Grand Prix seasons:

1.
The weight of the car without driver, fuel, oil, water or tires should not exceed 750 kg.
2. A minimum bodywork width of 850 mm at the driving seat.
3. Free choice of fuel.
4. All races must be over a minimum distance of 500 kilometers.

In the story, it recounts the famous legend of the switch from the traditional and official German white on Mercedes-Benz race cars to the colour silver.





Alfred Neubauer, the Mercedes-Benz racing manager of the time, claimed that the day before the June 3rd, 1934 international Eifel race, they weighed their newly introduced W25 Grand Prix race car, and found that it weighed over the 750kg limit, coming in at 752kg.

In a flash of inspiration, he had his technicians work overnight to remove the white paint, exposing the beautiful aluminum bodies of these technically advanced racers, bringing them to exactly 750kg, and they won the race. This sparked the legend of the “Silver Arrows”, as the press was to soon label them.

In the past few years, a few motorsport historians have questioned the credibility of the story.

As I researched my book “Silver Clouds: The 1934 Grand Prix Season”, I have to say that I developed the same doubts.





There are a few facts and insights that I can bring forward:

 1)
In the same year, Auto Union (a merger of Audi, DKW, Horch and Wanderer) presented their rear-engined Grand Prix cars under the same 750kg rules, never in any other colour but silver.

 2)
I find it hard to believe that in the thorough testing their sometimes white-painted W25, that the Mercedes-Benz technicians wouldn’t have weighed the racer well before any actual racing would take place.

 3)
The actual June 3rd, 1934 race was a Formule Libre race, and not under any of the restrictions of the 750kg Formula. In other words, it seems quite implausible that they would work so hard at removing 1kg of paint for an unrestricted race.


With these points, you can still ask, “Why the story then?


Well, for one point, it features the absolute precision of the Mercedes-Benz technicians and engineers, who considered the race machine only, not such frivolous things as the paint.


It also shows the creative quick-thinking of the legendary Mercedes-Benz race team manager Alfred Neubauer, always the clever strategizer.


Yes, it’s a damn good story, true or not …

Mercedes-Benz W25

Until 1934, three automotive companies dominated Grand Prix racing: Alfa Romeo, Bugatti, and Maserati. Each year, these companies produced racecars that were faster and more powerful than those of the previous year.

The Association Internationale des Automobile Clubs Reconnus (AIACR), the controlling body for motor sport in the 1930s, decided to change the requirements for the 1934, 1935, and 1936 Grand Prix seasons. The most important new requirement for the racers was that the maximum weight could not exceed 750 kg, excluding driver, fuel, oil, water, and tires.

The AIACR believed that Grand Prix cars were becoming too fast and reasoned that the change in weight parameters would limit the size of the engines used.

However, the AIACR had not at all taken into consideration the possibility of the manufacturers using new technology and lightweight metallurgy to create yet more powerful, efficient racers.

Mercedes-Benz saw an opportunity to move ahead, promoting their know-how and the sale of their products through Grand Prix racing.

Mercedes-Benz took a traditional approach with the front-engined rear-drive racer, but also took a serious look at using innovative aerodynamics and lightweight materials to give them an advantage. A steel-blocked 3.36-litre straight-8 supercharged engine powered the new Mercedes W25, and it was wrapped in a beautiful aerodynamic aluminum skin, with all-round independent suspension.

In that first year of the new formula, they won the Coppa Acerbo, the Italian Grand Prix and the Spanish Grand Prix. For 1935, they won 9 major races, giving driver Rudolf Caracciola the European Championship.
