Mercedes-Benz 300 SLR

The Mercedes-Benz 300 SLR was a special racing car made in the 1950s. It was built for sports racing and took part in the 1955 World Sportscar Championship. The car was known as the "SL-R," which stands for "sport, light, racing," and later became called "SLR." It was based on another racing car called the W 196 R but had a slightly bigger engine.

The 300 SLR had a powerful 3-litre engine that could produce 302 horsepower. Unlike its track-only cousin, the 300 SLR was changed to have two seats instead of one, and it got headlights so it could race on roads too. Famous racing driver Stirling Moss said it was "The greatest sports racing car ever built."

Only nine of these cars were made, and two of them were special closed cars called the "Uhlenhaut Coupé." These cars looked like normal cars on the outside but were built for racing. After a big accident at Le Mans ended Mercedes-Benz's racing, these special cars were put away. One of them became the personal car of a Mercedes-Benz engineer and was the fastest road car in the world at the time.

In 2022, one of these rare cars was sold for €135 million, making it the most expensive car to ever be sold. It was sold at an auction held at the Mercedes-Benz Museum.

History

Name

The Mercedes-Benz 300 SLR was not related to the 1952 W194 Le Mans racer or the 1954 300SL Gullwing road car. Instead, it was based on the successful 2.5-litre straight-eight-powered 1954–1955 Mercedes-Benz W196 Formula One car. Engineers made the engine bigger, up to 3.0 litres, for racing. They called it "SL-R" for Sport Leicht-Rennen (meaning Sport Light-Racing).

Racing record

In the 1955 World Sportscar Championship, Mercedes skipped some early races but still competed in others. Juan Manuel Fangio, driving for Mercedes, won the 1955 Argentine Grand Prix. Later, Stirling Moss won the 1955 Mille Miglia in a 300 SLR, setting a very fast record time.

Sadly, a big accident happened during the 1955 24 Hours of Le Mans. A Mercedes car lost control and crashed, causing many problems. After this, Mercedes stopped racing for a while.

The 300 SLR did well in other races, winning several events and helping Mercedes win the championship that year.

Uhlenhaut Coupé

Mercedes made two special road versions of the 300 SLR called Uhlenhaut Coupé. These cars were very fast, with one said to be the fastest road car of its time. One of these cars was kept by Mercedes and shown in its museum in Bad Cannstatt. The other was sold for a huge amount of money in 2022.

Technical description

The 300 SLR was a special racing car with its engine placed just behind the front wheels to balance the weight better. It had a very light body made from a special metal, which helped it stay light and fast.

Its engine was powerful and made to run on regular fuel. The car used special brakes and suspension to handle high speeds, and it even had a large rear spoiler to help slow it down during races.
