Uh oh. Did Carnegie Mellon University just steal Audi’s Matrix Beam headlight tech?

Nobody likes to be blinded while driving. Whether an oncoming vehicle simply has its brights on, or is just the right height to photonically stab into your irises, the strain on your eyes is annoying and dangerous.

According to Network World, researchers at Carnegie Mellon University (CMU) in Pittsburgh, PA may have a solution.

What the gurus at CMU have developed is an adaptive headlight system that selectively illuminates certain areas of the road, while omitting others. This could allow drivers to use their high beams without fear of distracting oncoming motorists.

“The programmable headlight senses and tracks virtually any number of oncoming drivers, blacking out only the small parts of the headlight beam that would otherwise shine into their eyes,” researchers at CMU’s Robotics Institute said.

The headlamps consist of a Digital Light Processing projector, an Intel i7 quad core processor, and an integrated camera. The array of gadgets splits the light into a million individual beams, each of which is controlled independently by the onboard processor.

The system doesn’t just protect the vision of oncoming traffic; it goes even further to protect the person sitting behind the wheel.

“During snow or rain showers, the headlight improves driver vision by tracking individual flakes and drops in the immediate vicinity of the car and blocking the narrow slivers of headlight beam that would otherwise illuminate the precipitation and reflect back into the driver’s eyes,” the researchers continued.

The assembly is impressive, yes, but CMU isn’t the first to play with adaptive headlights. In fact, Carnegie’s project sounds very similar to a technology that Audi debuted last year.

The German automaker previewed its ‘Matrix Beam’ headlights last February, another system that can dim, divert, and extinguish individual light beams based on environment.

Besides being first to the adaptive headlight party, Audi’s Matrix Beam headlamps also have an advantage in size. CMU’s units are currently larger than standard headlights, which may work for large commercial vehicles, but it would be difficult to implement on commuter cars. Audi’s Matrix Beams, conversely, were easily integrated into the 2013 Audi A8.

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