Honda Motor Co., Ltd. has detailed its next-generation technologies at its recent Automotive Technology Workshop. The preview focused on platforms for electrified models scheduled for release in the second half of the 2020s. This initiative supports Honda’s 2050 goals for carbon neutrality and zero traffic fatalities. The company aims to enhance EV and HEV competitiveness.
Highlights
- Next-Gen HEV Platform: A new mid-size hybrid platform, launching from 2027, reduces weight by 90 kg and uses a modular design for over 60% parts commonality.
- Large-Size Hybrid System: A new V6 hybrid system for North America targets over 30% fuel efficiency and 10% acceleration improvement compared to current ICE models.
- Super-ONE Compact EV: A new compact EV, launching in 2026, will feature a “Boost Mode” and a simulated 7-speed transmission to merge EV and ICE driving dynamics.
Next-Generation Mid-Size HEV Platform
Honda is advancing its hybrid system and HEV platform. New models will begin adopting this architecture from 2027.
The platform merges high rigidity with lightweight construction. It also features a modular architecture to increase parts commonality.
Honda’s goal is to enhance driving stability and performance, reinforcing the “joy of driving” concept even in electrified models.
Rigidity, Weight, and Driving Dynamics
The company established a new approach to body rigidity management.
By optimizing rigidity, body weight is reduced. This method also controls the load on each tire during cornering to improve roadholding.
This platform weighs 90 kg (198 lbs.) less than the current version. This is achieved through revised body structures and new engineering methods.
Honda plans to apply this lightweight, high-rigidity approach to its future EV platforms as well.
Modular Architecture and Efficiency
The modular design separates commonized modules, like the engine room, from unique modules, such as the rear cabin.
This strategy will increase new model development efficiency.
Honda targets over 60% parts commonality across models using this platform, enabling efficient production and cost control.
Advanced Vehicle Control
New vehicle control technologies are being adopted. This includes a Motion Management System using insights from Honda’s robotics development.
A new pitch control technology will be added to the existing Agile Handling Assist system to improve vehicle control under all road conditions.
Next-Generation Large-Size Hybrid System
Honda identifies HEV models as a core product group for the transition period before full EV popularization.
The North American market shows solid demand for large-size HEVs in the D-segment and larger.
Honda is developing a new system for these vehicles, focusing on power, towing capacity, and environmental performance for a late 2020s launch.
Engine and Performance Targets
The system includes a newly developed V6 engine compliant with stringent environmental regulations. It also uses new, low-cost, high-efficiency drive units and battery packs.
Key performance targets for these large HEVs, compared to current ICE models in the same segment, include:
- Fuel Efficiency: Improvement of more than 30%.
- Acceleration: Full-throttle performance improvement of more than 10%.
These goals will be met by combining the V6 engine’s efficiency with new energy management controls that optimize drive modes.
Super-ONE Prototype Compact EV Dynamics
The production model based on the Super-ONE Prototype will launch first in Japan in 2026. Subsequent launches are planned for the U.K. and other Asian markets.
The vehicle’s concept is defined as “e: Dash BOOSTER.”
Lightweight Platform and Handling
The EV uses a lightweight platform derived from the Honda N Series. It features a dedicated chassis with a widened tread and fenders.
Heavy components are consolidated, and a thin battery is placed at the center of the underbody.
This achieves a low center of gravity and makes it one of the lightest A-segment EVs, ensuring high responsiveness and stable handling.
Boost Mode and Simulated Transmission
The production model will feature an exclusive “Boost Mode.”
This mode increases power output while synchronizing a simulated 7-speed transmission and an Active Sound Control system.
The result generates a powerful engine sound and a sharp gearshift feel, simulating an ICE vehicle with a multi-gear transmission.
The system calculates simulated engine speed and gear position in real time based on driver input and vehicle behavior.
It even simulates the “kickdown” shock during acceleration and “fuel cut” behavior, integrating traditional ICE driving sensations into the EV.
