The Mercedes-Benz Silver Arrow race car made history 90 years ago

The white Mercedes-Benz W 25 was too heavy, so it lost the paint and won the race

Mercedes-Benz has a rich history of legendary cars on and off the track. The Mercedes-Benz 300 SL Gullwing may be the German brand’s most famous road car ever. The single-seat Mercedes-Benz W 25, also called the Silver Arrow, was the first of many race-winning cars with the same name. Even today, Mercedes Formula 1 cars are called “Silver Arrows,” but the original 1934 Silver Arrow set the standard for the Mercedes-Benz racers that followed. It’s been 90 years since this race car made its debut at the Eifel Race at the Nürburgring on June 3. Let’s take a look back.

Why the Mercedes-Benz Silver Arrow race car matters today

The W 25 wasn’t supposed to be silver. Actually, as was the case for most German racing cars, the W 25 was painted white. At the mandatory weigh-in before its first competition at the 1934 Eifel Race at the Nürburgring on June 3, 1934, however, the car was one kilogram heavier than the 750-kilogram limit. According to Mercedes-Benz lore, the night before the race, the team ground the paint of the W 25’s aluminum skin. When the car rolled to the starting line, it was the correct weight.

Spectators expecting a white race car were surprised to see the color change. However, the Silver Arrow nickname stuck when Manfred von Brauchitsch set a new track record with an average speed of 122.5 kilometers per hour to win the race in its initial competitive outing.

Even today, the W 25’s mechanicals sound impressive. The original Silver Arrow had a supercharged 3.4-liter in-line eight-cylinder M 25 A engine that produced 354 horsepower at 5,800 rpm. With the M 25 A engine, the W 25 had a maximum top speed of up to 300 kilometers per hour (186 mph). The car’s hood also had quick-release fasteners to facilitate access for any necessary work or adjustments during races. Then, as now, quick pit stops could be the difference between winning and losing a race.

The W 25 Silver Arrow is on display at the Mercedes-Benz Museum in Stuttgart, Germany. The W 25 and other silver race cars are in a room fittingly named “Silver Arrows—Races and Records.”

For those old enough to remember Skynet from the Terminator franchise, we are one step closer to seeing artificial intelligence coming online and taking over the world. At least, that's the conspiracy theorist side of things. Of course, if you are a bit younger, another movie called iRobot showed us that AI can lead us into a new understanding of what it means to be human (after some dramatic Will Smith-inspired action ensues).

So it should not be surprising that a new press release from Mercedes-Benz revealing they have begun adding ChatGPT via Microsoft Azure OpenAI Service to over 900,000 vehicles is somewhat polarizing.

Mercedes-Benz gives the GLS a slightly updated design and new tech for 2024
The mid-cycle refresh also includes more power for the base GLS trims

Sneak a peek at the 2024 Mercedes-Benz GLS and you might notice that the large SUV looks slightly different. Mercedes’ largest SUV is getting a mid-cycle refresh for 2024, bringing an updated look, more powerful engines, new tech, and more features for the SUV. The changes may be slight, but they’re there and they're coming after similar changes to the GLC and CLA.
Fans of the old GLS shouldn’t worry about the 2024’s updated exterior design, as the minor changes mostly affect the front end. The large SUV’s front grille has been updated with new horizontal slats, and there’s new black trim that surrounds the grille to showcase its size. The four louvers in the grille are finished in “Silver Shadow,” which is a fancy way of saying dark chrome in Mercedes. Some slight changes have been made to the front bumper, and new taillights are the only changes that Mercedes has made at the back.

Mercedes just integrated TikTok into its in-car entertainment system (really)
The third-party app will displayed on the 2024 E-Class’ enormous and high-tech Superscreen

Mercedes-Benz is consistently at the forefront of innovation. Depending on who you ask, Mercedes-Benz was the first to introduce the modern automobile, to place brakes on all four wheels of a car, and come out with crumple zones for safety. Not sexy, but definitely innovative stuff. Mercedes just gave the world the first glimpse at the 2024 E-Class, and the midsize sedan is an absolute powerhouse on the tech front. The automaker's best seller arrives with a new Superscreen system and native third-party access to popular entertainment apps like Angry Birds, Zoom, Vilvadi web browser, Webex by Cisco, and TikTok.

While GOP leaders in red states are trying to ban TikTok in the United States, claiming that the app provides the Chinese government with sensitive information, Mercedes-Benz has pulled a hold-my-non-alcoholic-beer moment by bringing the app to the new E-Class with its new MB.OS operating system. Obviously, Mercedes doesn’t want you to access TikTok while driving, because recording how you’re going to steal a Hyundai or Kia, which is something you probably learned on TikTok, from behind the wheel of your Mercedes E-Class just isn’t safe. Owners will be able to access TikTok, and other apps, through the infotainment system when the car is parked. Since the E-Class’ dashboard has two screens, your passenger can join in on all the fun that TikTok offers.
