Supplier's note

  1. Three Technical Breakthroughs:

    • Aluminum Block Design: Reduces weight by 20% compared to cast-iron engines, improving vehicle agility.
    • Turbocharged Efficiency: Delivers 15–25% higher torque at low RPMs than naturally aspirated 2.5L engines.
    • Emissions Compliance: EU Stage III certification ensures compatibility with global regulatory standards.

  2. Optimal Version Selection:

    • Base Model: Ideal for daily commuters or light commercial use where cost-effectiveness is prioritized.
    • Advanced Model: Suitable for enthusiasts seeking improved towing capacity or off-road performance.
    • Pro Model: Designed for heavy-duty applications like agricultural machinery or industrial equipment, offering 30% higher torque than baseline models.

With its compact inline-four layout, the Pro version’s enhanced torque enables safe handling of heavy payloads. When paired with its aluminum block, this creates a 20% improvement in power-to-weight ratio compared to competitors, ensuring superior performance in rugged environments.

Note: Performance gains are relative to the Base Model specifications. Actual results may vary based on vehicle configuration and usage.
