Lightweight design: H1 platform modular design, featuring integrated wiring harness, integrated engine cooling/oil cooling module, and cast aluminum flywheel housing.

Excellent NVH performance: Vibration-damping and noise-reducing oil pan further reduces vibration and noise, being 1–3 dB(A) lower than competing products.

Powerful performance: High-tumble intake technology achieves a comprehensive breakthrough in power, with a peak torque of 1950 N·m.

Aesthetic upgrade: Family-style design, with smoother and more aesthetic gas and electrical routing.
