Key Feature 1
Outstanding motor capability
The best torque density & fuel efficiency in the same segment
Key Feature 2
Improved power performance
Improved fuel efficiency and acceleration functions with increased gear ratio range
Key Feature 3
Optimal installation compatibility
Installation compatibility improvement with optimal layout designs
Motor power density has improved with a permanent magnet synchronous motor (PMSM) type for enhanced installation compatibility. Motor coils with the application of coil winding technology at 90 degrees and the latest bobbin design technology are also applied for better coil space factor. Improved motor cooling performance with ATF cooling for the high-efficient and functioning motor
The 8-speed hybrid AT is the common 8-speed AT with ultra-efficient motor and engine clutch. Torque converters in the common 8-speed AT are replaced with hybrid engine clutch and torsion damper. It brings better fuel efficiency and speed change quality and presents a smooth start and less impact from shifting gears. It improves fuel efficiency by actively engaging EV and HEV modes through the motor.
02
Engine clutch (wet)
It turns on when switching EV↔hybrid mode and connects or disconnects the driving force between engine and transmission.
