Mercedes to launch ‘Car-to-X’ vehicle-to-vehicle communication tech

Mercedes-Benz Car-to-XCars are getting chatty. The U.S. Department of Transportation, National Highway Traffic Safety Administration, and the University of Michigan are currently testing “vehicle-to-vehicle” (V2V) technology, which allows cars to sense each other and the environment and, hopefully, anticipate crashes.

Mercedes-Benz is getting in on the action too. The company announced that it will put its own V2V system, called Car-to-X in the hands of drivers by the end of the year.

Like the V2V systems being tested in Michigan, Car-to-X is intended as an early warning system that can identify hazards and warn the driver, potentially giving them enough time to prevent a crash.

Initially, Car-to-X won’t be fully integrated with a Mercedes’ hardware. It will work through a smartphone app called Digital DriveStyle, which receives data and feeds it to the car’s onboard displays.

This may sound like an aftermarket job, and that’s because it is: By packaging Car-to-X in this way, Mercedes says owners will be able to retrofit any car they want with the system.

Once it’s synced, Car-to-X will scan the airwaves for warnings from emergency services and reports on bad weather. Since Mercedes cars already come equipped with a variety of sensors, they can also transmit and receive information on road conditions.

This is where the “talking” aspect comes in: As a car approaches an obstacle, such as a crash or a patch of bad weather, it will receive warnings from other cars that have recently passed through the area, and then pass the message on. It’s like a robotic version of crowd-sourcing.

However, drivers have to manually activate the notifications by pressing a button. This should cut down on distracted driving, but it won’t help drivers in urgent situations, such as wrong-way driving or when they are rapidly approaching an obstacle.

The system is also limited by how many cars are part of the network. For now, only Mercedes vehicles will be able to talk to each other with Car-to-X, although Mercedes would also like to equip emergency maintenance vehicles with the system to enhance its effectiveness.

These flaws don’t worry Mercedes, which considers Car-to-X a work in progress and a stepping stone to future technologies.

“With Car-to-X communication we have made a base technology ready for the market which in the future will enable a new generation of driver assistance systems to be developed,” said Prof. Dr. Thomas Weber, the Daimler AG board member in charge of Mercedes cars.

“Through the intelligent fusion of sensor data, we are able to obtain an extremely precise picture of the vehicles surrounding including areas further away from the vehicle – which also helps us with the further development of our autonomous driving functions.”

Mercedes-Benz G580 first drive: old-school off-roader goes electric
2025 Mercedes-Benz G580 from three quarter view.

American car buyers mostly know Mercedes-Benz as a luxury brand. But for decades, the automaker has also produced the tough, rugged G-Class (also known as the Geländewagen or G-Wagen), an SUV not afraid to get its leather upholstery muddy. And now, this iconic Mercedes is going electric.

The 2025 Mercedes-Benz G580 with EQ Technology — the final name of the SUV previously known as the EQG — isn’t the first electric off-roader. The Rivian R1S and R1T and GMC Hummer EV have proven that electric powertrains and off-roading are a great combination. But the electric G-Wagen is different because it’s based on an internal-combustion model — and a very traditional one at that.

Honda believes hydrogen semi trucks will make the case for fuel cells
Honda hydrogen fuel-cell semi truck.

Honda remains committed to hydrogen fuel-cell vehicles, but the market for those vehicles remains limited. So Honda is looking at other uses for fuel cells -- including commercial trucks.

To show how that could work, Honda converted a semi truck to fuel-cell power, replacing its diesel engine with three fuel-cell modules. Together, the three modules produce a combined 321 horsepower, and can propel the truck to a top speed of 70 mph. There's enough onboard hydrogen storage capacity for a 400-mile range with a full load, Honda claims.

Mercedes-Benz G580 vs Rivian R2: Is the much cheaper Rivian actually better?
2025 Mercedes-Benz G580 from three quarter view.

Mercedes-Benz has finally taken the wraps off of the new "Mercedes-Benz G580 with EQ Technology." Yeah, it's a mouthful, but it's basically a new electric G-Wagon. It looks a lot like the G-Wagon you know and love, but with an electric powertrain and a battery. It's not the only electric SUV out there, however, and there are some great ones -- like the Rivian R2.

Both the Mercedes G580 and the Rivian R2 have a lot going for them, but they also approach the electric SUV slightly differently. Is one better than the other? I put the two head-to-head to find out.

The approach that the two vehicles take to design is quite different -- and you might like one better than the other.
