Complete Overview of Hyundai’s 2nd-Generation Hybrid System
Hybrid technology is no longer just about fuel efficiency.
Hyundai Motor Company has recently unveiled its second-generation hybrid system, offering not only improved efficiency but also enhanced driving enjoyment, EV-level convenience features, and ride quality.
In this article, we’ll explore the key structural changes, advanced features, and how Hyundai's system compares with its main competitor, Toyota.
1. Structural Evolution of the Hybrid System
Why the P1+P2 Parallel Motor Setup Matters
Hyundai's second-generation hybrid system expands upon the traditional TMED platform by separating the P1 and P2 motors into a parallel configuration.
- P1 motor is directly connected to the engine, handling starting, electricity generation, and regenerative braking.
- P2 motor is connected to the transmission, assisting propulsion or enabling EV driving mode.
This dual-motor setup reduces energy loss and extends pure electric driving range.
It plays a critical role in enhancing energy efficiency, quiet startups, and smooth engine transitions, significantly improving the overall driving experience.
2. Advanced Convenience Features: Stay Mode & V2L
Hybrids That Act Like EVs
One standout feature of this new system is its EV-like smart functionality.
▪ Stay Mode
- Allows the vehicle’s electronics (AC, audio, lights) to function even with the engine off.
- Can operate for up to one hour depending on battery level.
- Navigation-based charging presets allow for automatic battery preparation when Stay Mode is expected.
▪ V2L (Vehicle to Load)
- Supplies external power using the vehicle’s high-voltage battery.
- Supports up to 3.6kW of output.
- Useful for outdoor camping, powering electronics, or emergency use.
- Engine can automatically activate to recharge the battery and maintain power output.
Hybrids are now evolving into “mobile energy hubs”, offering far more than just great fuel economy.
3. A New Era in Ride Quality: e-VMC 2.0 System
Controlling Comfort Through Electric Motors
e-VMC 2.0 (Electrification-Vehicle Motion Control) is one of the system’s highlights.
It uses precise electric motor control to adjust vehicle dynamics, enhancing both comfort and safety.
▪ Key Components
- e-Ride 2.0: Reduces vertical motion when crossing speed bumps.
- e-Handling 2.0: Suppresses body roll during cornering.
- e-EHA 2.0: Enhances stability during sudden steering or evasive maneuvers.
This system delivers a luxury-level ride even in a hybrid SUV, especially noticeable in high-speed or uneven road conditions.
4. Still 6-Speed, and For Good Reason
Why Hyundai Stuck With a 6-Speed Automatic
Hyundai continues to use a 6-speed automatic transmission in its hybrid system.
This is not a cost-saving measure, but rather a deliberate design optimized for hybrid operation and motor synchronization.
- Improves regenerative braking efficiency
- Enhances synchronization with electric motors
- Simplified structure for better serviceability and durability
- Retains the shifting feel of traditional combustion vehicles
Ultimately, the 6-speed automatic bridges the gap between EV and ICE drivetrains, providing the best of both worlds.
5. Case Study: Palisade Hybrid
The First to Showcase Hyundai’s New System
Hyundai’s flagship SUV, the Palisade Hybrid, is the first model to feature the new system.
- 2.5L turbocharged engine + 54kW electric motor
- Total system output: 334 horsepower
- Estimated fuel efficiency improvement: 14–17%
- Equipped with e-VMC 2.0, Stay Mode, and V2L features
This model validates the system’s power, efficiency, and real-world usability. It also serves as a foundation for rollout to other mid- and full-size vehicles.
The most striking aspect is its 334 horsepower output, one of the highest in its class among hybrid SUVs. This positions it as more than just a fuel-saving model—it's an all-around SUV capable of towing, off-roading, and long-distance driving.
Thanks to the combination of instant electric torque and turbo power, Hyundai is clearly targeting outdoor lifestyle and recreational users. With V2L included, the Palisade becomes a “mobile camping hub”.
In short, this isn’t just a system launch—it's a bold statement that Hyundai hybrids can deliver both performance and versatility.
6. Toyota THS vs. Hyundai’s 2nd-Gen Hybrid System
Differences in Architecture, Driving Feel, and Strategy
| Category | Toyota THS | Hyundai 2nd-Gen System |
|---|---|---|
| System Architecture | Power-split (e-CVT) Planetary gearset for electronic power distribution |
Parallel P1+P2 motors with 6-speed automatic Each motor optimized for distinct roles |
| Motor Roles | MG1: starter/generator MG2: propulsion + regeneration |
P1: start/generation P2: propulsion + regeneration (primary driving support) |
| Driving Feel | Efficiency-focused, smooth Some rubber-band feel from e-CVT |
Responsive and engaging Maintains shift sensation for driving enjoyment |
| Convenience Features | Functionally minimal for simplicity | EV-level features: V2L, Stay Mode, e-VMC |
| Strategic Approach | Hybrid as a long-term mainstream drivetrain | Hybrid as a bridge toward full electrification |
Toyota’s THS is widely considered the benchmark for hybrid systems, known for exceptional fuel efficiency and reliability.
However, its power-split structure and e-CVT can result in a somewhat unnatural driving feel.
Hyundai’s 2nd-generation system, by contrast, combines a traditional automatic transmission with dual-motor control, creating a more engaging driving experience while embracing high-end EV-like features.
In short, Toyota offers a refined, efficiency-first hybrid, while
Hyundai delivers an experience-focused hybrid that blends power, practicality, and innovation.
Conclusion: A New Standard Beyond Fuel Economy
Hyundai’s second-generation hybrid system isn’t just about saving fuel.
It’s a full-featured, electrified drivetrain that integrates motor control technology, EV-grade convenience, dynamic driving, and practical use cases.
Starting with the Palisade, this system is expected to expand across various vehicle classes.
For Hyundai, hybrids are not just transitional—they’re complete, well-rounded powertrains in their own right.
