With the continuous popularization of AI autonomous driving in automobiles, more and more people are beginning to experience autonomous driving. An increasing number of consumers prioritize a Car’s autonomous driving level when selecting a car. This raises the question: “What are Level 2 autonomous cars?” – a query of global interest. Therefore, Ahcarsale presents the 2025 Global Level 2 Autonomous Car List. Let’s explore together!
I. What is Level 2 (L2) Autonomous Driving?
Functional Scope of L2 Autonomous Driving
Must simultaneously achieve lateral control (e.g., Lane Keeping Assist (LKA), automatic steering) and longitudinal control (e.g., Adaptive Cruise Control (ACC), Automatic Emergency Braking (AEB)).
Common function combinations: ACC + LKA + Automatic Parking Assist (APA) + Traffic Sign Recognition (TSR).
Human-Machine Responsibility Division in L2 Autonomous Driving
The system serves only as “driving assistance.” The driver must continuously monitor the road environment and be ready to take over immediately. This fundamentally differs from “autonomous driving” at L3+.
Chinese standards classify L1-L2 as “assisted driving,” while L3-L5 qualify as “autonomous driving.”
Technical Implementation of L2 Autonomous Driving
Relies on multi-sensor fusion (cameras, radar, ultrasonic sensors). Some models include basic high-precision maps.
Hardware costs are low, achieving full coverage across cars priced between ¥100,000 and ¥300,000.
After understanding L2 autonomous driving, many may be interested in definitions for L1-L5 levels. Click to view Ahcarsale’s previous blog: Autonomous Driving Levels Explained.
II. Global L2 Autonomous cars
(I) International Brands
| Brand | Representative Models | Technical Solution/Key Features |
| Tesla | Model 3/S/X | Autopilot/FSD (includes automatic lane change, navigation assist) |
| Audi | A4/A8 | Audi AI (traffic jam assist + adaptive cruise) |
| BMW | 5 Series/X5 | Driving Assistant Professional |
| Mercedes | C-Class/E-Class/S-Class | Drive Pilot (base version) |
| Volvo | S90/XC90 | Pilot Assist (with emergency avoidance) |
| Volkswagen | Tayron | Travel Assist (full-speed cruise + lane centering) |
(II) Chinese Brands (Including New Forces)
| Brand | Representative Models | Technical Solution/Key Features |
| GAC NE | Aion S/LX | ADiGO 2.0 (highway assist + automatic parking) |
| XPeng | G3/P5/P7 | XPILOT 3.0 (NGP highway navigation assist) |
| NIO | ES8/ET5/ET7 | NIO Pilot (automatic emergency braking + road sign recognition) |
| Changan | CS55/CS75/UNI-T | IACC Integrated Adaptive Cruise (China’s first mass-produced L2) |
| Geely | Binrui/Boyue/Xingyue L | G-Pilot (includes automatic parking + traffic jam assist) |
| Great Wall | WEY VV6/Haval H6/F7 | Smart Cruise (curve assist + start-stop following) |
| Hongqi | H9 | First CL2-certified model (outstanding safety measures) |
| Leapmotor | C11 | Leap Pilot 3.0 (supported by 28 perception hardware units) |
Note: CL2 certification was jointly launched by China Automotive Technology and Research Center (CATARC) and SAE. Hongqi H9, GAC Aion LX, and Bestune T99 are the first certified models. Certification covers functional safety, system stability, and collision avoidance capabilities.
III. Technical Advancements & Controversial Cases
Wenjie M5 Smart Driving Edition
Classified as “L2.999,” supports advanced functions like active lane changes and unprotected left turns, but still requires driver supervision.
Tesla Controversy
Although marketed as “Full Self-Driving (FSD),” SAE and MIIT explicitly classify it as L2 because the system cannot independently assume driving responsibility.
IV. Industry Penetration Trends & Purchasing Advice
Market Status
- Since 2020, L2 functionality has become standard in mid-to-high-end models.
- By 2024, penetration exceeded 60% (for models priced above ¥150,000).
- Basic L2 features are now widespread in ¥100,000 economy models (e.g., Changan CS55, Geely Binrui).
Purchasing Considerations
- Prioritize official certification: Choose models certified under CL2 (China) or E-NCAP assisted driving ratings.
- Functional performance gaps: Significant differences exist within L2 systems (e.g., Tesla FSD vs. Haval H6 cruise assist). Test drives are essential.
- Regulatory restrictions: Some functions (e.g., automatic lane changes) are region-locked. Confirm local availability before purchase.
Reiteration of Authoritative Definitions
- SAE J3016 Standard: L2 is “Partial Automation.” The driver is the responsible entity; the system is merely an executor.
- China National Standard GB/T 40429-2021: L0-L2 are collectively termed “Driving Assistance.” Drivers must not remove hands from the wheel or eyes off the road while functions are active.
Recommendation: Always refer to the automaker’s official configuration sheet. Be wary of marketing terms like “L2.5” or “L2+.” Focus on functional availability, clarity of system takeover prompts, and superior safety redundancy design (e.g., dual braking systems).
