The original model: a technical revolution
The Mercedes W 125 was developed in 1937 to dominate European Grand Prix circuits in the 750 kg racing formula. This revolutionary car was powered by a supercharged 5.66-liter V12 engine producing nearly 646 horsepower—a phenomenal output for the time. Its innovative tubular chassis and aerodynamic bodywork made it a formidable machine.
The W 125 set numerous speed records and won several Grand Prix races during the 1937 season, notably thanks to legendary drivers such as Rudolf Caracciola and Hermann Lang. Its advanced technical design, with its hydraulic brakes and independent suspension, had a lasting influence on the development of the racing car.
This machine represented the pinnacle of German automotive technology in the 1930s, combining raw power and technical refinement in an approach that foreshadowed future Formula 1 cars.
Mercedes-Benz in the 1930s
In the 1930s, Mercedes-Benz experienced a technical golden age driven by its visionary engineers. The brand with the star invested heavily in motor racing, viewing the racetrack as a laboratory for innovation to develop technologies that would then benefit its production models.
The "Silver Arrows" era marked the height of this philosophy, with considerable budgets allocated to the development of revolutionary racing cars. Mercedes-Benz competed directly with Auto Union in a frantic technological race that pushed the boundaries of automotive engineering. This heyday definitively established Mercedes-Benz's reputation for performance and technical innovation, a legacy that continues to this day in both its road and competition models.
The Silver Arrows: A Legend Born by Chance
The story of Mercedes's famous "Silver Arrows" begins with a technical stroke of fate . During practice for the 1934 Eifel Grand Prix, Mercedes engineers discovered that their car exceeded the permitted weight limit by just a few kilograms. In an emergency, they decided to completely sand down the traditional German white paint to lighten the machine.
This makeshift solution reveals the raw aluminum bodywork, creating that distinctive silver hue. Not only did this modification comply with regulations, but it also resulted in one of the most iconic liveries in motor racing history. Driver Manfred von Brauchitsch won the race, launching the legend of the "Silberpfeile."
The Mercedes W 125 continued this aesthetic tradition in 1937, but this time by deliberate choice. This silver color had become the symbol of German technical dominance on European circuits. Ironically, what began as an emergency solution became the most recognizable visual identity in motorsport at the time, still inspiring the liveries of Mercedes racing cars today.
This anecdote perfectly illustrates how innovation can be born from constraint, a philosophy that characterized the pioneering spirit of car manufacturers in the 1930s .

Frequently Asked Questions
How to understand the scales of miniatures?
Scale indicates the reduction ratio between the real car and the miniature. For example, at 1:43 scale, each centimeter on the miniature corresponds to 43 centimeters on the real vehicle.
Concretely, a 1/18 scale Ferrari model is approximately 25-30 cm long, while in 1/43 scale it measures approximately 10 cm.
What scales are available?
Our model cars are mainly offered in 1/43, 1/24, 1/18 and 1/87 (HO) scales. The scale is always indicated in the product sheet.
The smaller the second number, the larger the model car (e.g. 1/18 is larger than 1/43).
