Which Car Door Handle Is the Most Practical in the New Energy Era?
When we think about cars, the door handle may seem like a small detail—but it actually plays a crucial role, combining functionality, safety, and aesthetics. In today’s rapidly evolving automotive market, especially in the new energy vehicle (NEV) era, door handle designs have diversified.
Currently, the most common types can be grouped into four categories: Electric Pop-out, Press-to-Release Hidden, Semi-Hidden, and Traditional External Handles. Let’s break them down and see their pros and cons.

⚡ Electric Pop-out Handles
This type became popular with the rise of NEVs. When the owner approaches and unlocks the car, the handle automatically extends; once locked, it retracts. The design first appeared on the Tesla Model S in 2012, and has since been widely adopted by other automakers.
✅ Pros:
Offers a strong sense of ceremony and futuristic tech.
Enhances the vehicle’s aerodynamics by reducing drag.
Studies show four hidden handles can reduce drag coefficient by 0.012 Cd, adding ~5 km of range.
❌ Cons:
In cold climates (e.g., -20°C), handles may freeze and fail, causing major inconvenience.
More complex structure, meaning higher failure rates—reportedly 3x that of traditional handles.
Expensive to repair and may fail during power loss, creating risks during emergencies and rescue situations.
🔘 Press-to-Release Hidden Handles
These handles use a lever mechanism: press one end, and the other pops out for pulling. Like electric pop-outs, they sit flush with the body when not in use, giving the car a sleek look.
✅ Pros:
Maintains a clean, modern exterior.
Offers some aerodynamic benefits.
❌ Cons:
Requires extra steps (press first, then pull), making it less convenient.
Possible pinching hazard if misused.
Complex internals lead to higher repair costs and potential reliability issues.
May cause delays in emergencies if the handle jams.
🔲 Semi-Hidden Handles
A popular modern compromise, semi-hidden handles strike a balance between aesthetics and usability. They remain partly integrated into the body but still allow a traditional pulling motion.
✅ Pros:
Blend style and practicality.
Easy to operate like traditional handles while reducing drag.
Typically support both electronic and mechanical control, ensuring reliability even if the car loses power.
Offer better safety and dependability compared to full hidden designs.
❌ Cons:
In extreme crash or deformation scenarios, opening may still be affected—but performance remains better than fully hidden options.
🛠️ Traditional External Handles
These classic handles remain a trusted standard, especially on internal combustion engine (ICE) cars.
✅ Pros:
Simple structure with high reliability.
Easy to operate—universally intuitive.
Remain functional even if the car loses power or wiring fails.
Low repair costs and excellent long-term durability.
❌ Cons:
Outdated aesthetics—lacks modern flair and tech appeal.
Creates more wind resistance, increasing cabin noise and potentially reducing efficiency.
📜 Policies & Industry Trends
National Standards in Development:
China’s Ministry of Industry and Information Technology (MIIT) is drafting mandatory safety standards for car door handles, covering redundancy, emergency labels, mechanical strength, and anti-pinch functions.Industry Shift:
Once seen as a status symbol for NEVs, hidden handles are now criticized by experts as a “user-unfriendly design” due to safety and practicality issues. Automakers are introducing mechanical redundancies and safety indicators, while giving users more options to balance looks with reliability.
📊 Door Handle Comparison Table
| Type | Aesthetics | Tech Appeal | Aero / Range Gain | Ease of Use | Safety (Power Loss/Rescue) | Reliability / Repair Cost |
|---|---|---|---|---|---|---|
| Electric Pop-out | High | High | Medium (~5–10 km) | Medium | Low | Low / High |
| Press-to-Release | Medium | Medium | Medium | Lower | Medium | Medium |
| Semi-Hidden | Med-High | Med-High | Medium | High | High | Medium |
| Traditional External | Low | Low | Low | High | Very High | Very High / Low Cost |
🏆 Conclusion: The Most Practical Choice
In the NEV era, design and practicality must coexist. While electric pop-out and press-to-release handles look futuristic, their reliability issues raise concerns.
Based on current industry practice, policies, and user experience, the Semi-Hidden Handle (as seen on models like the Xiaomi SU7) stands out. It balances aesthetics, ease of use, and safety, making it the most practical door handle design today.
