Which cars have L3 autonomous driving?

[IanDella]

Currently, the only car that can achieve L3 autonomous driving level is the all-new Audi A8. L3 autonomous driving level: The L3 autonomous driving level means that the car's automated system can both perform certain driving tasks and monitor the driving environment under certain conditions, but the driver must be ready to regain control of the vehicle. Autonomous driving is divided into levels, and L3 actually stands for Level-3, which is considered an intermediate level. Equipped with the zFAS computer platform: The Audi A8 is equipped with the zFAS computer platform, which processes real-time information from 12 ultrasonic sensors, along with four 360-degree cameras, four mid-range radars, one long-range radar, and a laser scanner, ensuring safe autonomous driving.

Last month I test drove a Mercedes-Benz S-Class, and its Level 3 autonomous driving feature was incredibly useful on the highway. Driving from the city to the suburbs, after setting the speed, the car controlled the steering and acceleration by itself—I could sip coffee or check navigation occasionally. But don’t get distracted for too long; the system alerts you with sounds and lights when it’s time to take over, like when encountering sudden construction zones. The Honda Legend also supports Level 3 in some parts of Japan, and I’ve seen forum users share how great it is for stop-and-go traffic. The BMW i7 is smooth too, with prompt takeover responses. These are all luxury models with hefty price tags, but they save a lot of effort on long drives. The key is to only use them on clear-weather, obstacle-free highway sections—safety first, always be ready to intervene. Level 3 isn’t widespread yet, mostly limited to high-end models from these brands, but once you’ve tried it, you’ll see how technology transforms driving.

I'm fascinated by Level 3 autonomous driving technology, which enables partial self-driving but requires the driver to take over when the system requests. Supported models include the Mercedes-Benz S-Class and EQS equipped with the Drive Pilot system, available on German highways with speed limited below 60km/h; the BMW i7 and 7 Series' Personal Pilot function operates smoothly on specific road sections; the Honda Legend has been tested for urban L3 applications in Japan. The technology relies on lidar and cameras to monitor the environment in real-time, ensuring stable lane keeping and distance control. Unlike L2, L3 can temporarily relieve monitoring responsibility but requires readiness to respond to alerts. The challenges are strict regulations with approval only in regions like the EU, and high costs for batteries and chips. The future potential is significant if safety standards can be addressed, possibly expanding to more road sections.

L3 vehicle safety is crucial, and usage rules must be strictly followed. I understand that the Mercedes-Benz S-Class supports the L3 driving system taking partial control on highways, but drivers must respond quickly to takeover signals. The Honda Legend has optimized its traffic jam pilot mode, making it suitable for certain roads in Japan. The BMW i7 also features similar functions with responsive performance. Usage is limited to good weather and open highways; otherwise, the system may deactivate or require manual intervention. Safety designs minimize the risk of misoperation to ensure a smooth journey. Currently, L3 models are scarce, available only from high-end brands with limited application scope. It is advisable to study the vehicle manual thoroughly before hitting the road.

Comparison of current L3 vehicles: The Mercedes S-Class's Drive Pilot offers smooth driving, particularly comfortable in straight-line driving with clear system takeover prompts; the Honda Legend excels in congested environments but has speed limitations; the BMW i7 responds faster in curves, providing a more dynamic driving feel. Personally, I found the Mercedes system more user-friendly, while the BMW's high integration makes it better suited for routes with many curves. These vehicles are only available in approved countries like Germany or Japan, with sensor fusion technology at their core ensuring precise vehicle distance control. The key differences lie in Mercedes focusing on comfort, Honda targeting urban use, and BMW emphasizing handling. L3 features are beneficial for long-distance driving by reducing fatigue, but require matching conditions to ensure safety.
