When NVIDIA CEO Jensen Huang took the stage at CES 2026, he brought Mercedes-Benz CEO Ola Källenius along for what turned out to be one of the show’s biggest announcements. After five years and thousands of engineers working together, the two companies revealed their first full-stack autonomous vehicle system, and it’s hitting the road in the 2026 Mercedes-Benz CLA this quarter. This one actually exists, with a price tag and a launch date.
- Mercedes-Benz and NVIDIA spent five years building a complete autonomous driving system called Alpamayo, which launched in Q1 2026.
- The 2026 Mercedes-Benz CLA features NVIDIA’s full AV stack with 27 sensors including 10 cameras, 5 radar units, and 12 ultrasonic sensors for Level 2++ autonomous driving.
- The system costs $3,950 for three years in the U.S. and can handle city streets from point to point, managing traffic lights, lane changes, and complex urban scenarios.
Five Years of Building Something Different
The partnership between Mercedes-Benz and NVIDIA took several thousand people and at least five years of work. Huang described Alpamayo as NVIDIA’s first full-stack effort for autonomous vehicles. Full-stack means everything from the chips inside the car to the AI models making decisions to the safety systems keeping you alive.
According to Huang, “in the case of Mercedes Benz, we built the entire stack together. We’re going to deploy the carbon, operate the stack, and maintain the stack for as long as we shall live.” When you buy a Mercedes E-Class Sedan or the new CLA with this technology, you’re getting a system that will keep improving through over-the-air updates, similar to how your smartphone gets better with software updates.
Safety First, Speed Second
Källenius emphasized that the NVIDIA collaboration revolves around safety, saying “If you’re moving an object that weighs 4,000 pounds, and it’s moving at 50 miles an hour, sorry is not going to cut it. There needs to be a higher level of certainty and safety.” For each control decision, the AI evaluates 10 possible outcomes to ensure safe driving.
The system uses dual AI stacks, one for normal driving and one for safety. The car mostly drives with an end-to-end system that uses AI to read visual sensors and chart a path, but NVIDIA also built a second, safety-oriented stack that uses strict rules to take over when the AI is unsure. Every line of code in the data stack Mercedes built with NVIDIA is safety assessed.
What You’ll Actually Experience Behind the Wheel
Källenius noted he had “a chance with the combined Mercedes and NVIDIA team to drive it through San Francisco,” describing how “it feels that the car is on rails you’re just driving, and it does everything. I drove uninterrupted for more than an hour through pretty heavy traffic.”
One safety driver employed by Mercedes-Benz said the car was driving itself for 90% of the ride through San Francisco, a tricky city to drive in with big hills, frequent red lights and trucks unloading in the middle of streets. The system handled lane changes, worked around double-parked cars, yielded to reversing vehicles, and made unprotected left turns.
The 2025 Mercedes-Benz CLA will be the first production vehicle to ship with NVIDIA’s entire AV stack, including the new Alpamayo reasoning capabilities. The Alpamayo 1 model is a 10-billion-parameter Vision-Language-Action model designed to handle those weird edge cases that usually cause self-driving systems to fail. Older self-driving systems could see the road. Alpamayo can reason about it.
What Mercedes Buyers Need to Know
Mercedes is selling the tech, called MB.DRIVE ASSIST PRO, for $3,950 for three years in the U.S., with monthly and yearly pricing options coming later. Compare that to Tesla’s Full Self-Driving, which costs $8,000 a year or $99 a month, and the Mercedes system starts to look like a bargain.
If Mercedes actually ships a car in Q1 that can have similar capabilities as Tesla’s FSD, based on an open-sourced system that any automaker can buy, it could shake up the industry. NVIDIA works with other automakers including Lucid, JLR, and Uber who have shown interest in the Alpamayo platform.
Why This Time Feels Different
Previous autonomous driving promises have come and gone. Three things make this announcement different: it exists, you can buy it, and it comes from two companies with reputations to protect. Mercedes-Benz has been making cars since 1886. NVIDIA powers most of the AI revolution. Neither company can afford to ship something that doesn’t work.
Real vehicles with real systems are shipping to real customers this quarter. The partnership also shows how the car industry is changing. Traditional automakers realized they can’t build cutting-edge AI systems on their own. Tech companies learned they need automotive expertise to meet safety standards. When you combine Mercedes-Benz’s 130-plus years of car-building knowledge with NVIDIA’s AI capabilities, you get something neither could build alone.
