Supplier's note

  1. Three Technical Breakthroughs:

    • High-Displacement Scalability: The 4.8L Pro Model delivers 443 lb-ft of torque—20% higher than industry benchmarks—enabling rapid acceleration in luxury SUVs like the X5.
    • Material Hybrid Construction: Cast iron blocks with aluminum heads reduce weight by 15% compared to all-iron engines, improving fuel efficiency without sacrificing strength.
    • Turbocharged Efficiency: The N55’s twin-turbo setup (in Pro models) ensures 385 HP at lower RPMs, outperforming naturally aspirated engines in mid-range power.

  2. Optimal Version Selection:

    • Base Model (2.0L): Ideal for daily drivers or compact BMWs (e.g., 320i) prioritizing fuel efficiency and cost-effectiveness.
    • Advanced Model (3.0L): Perfect for sporty sedans (e.g., 330i, 530i) needing a balance of power and practicality.
    • Pro Model (4.4L/4.8L): Designed for high-performance vehicles like the 6 Series or X5 xDrive, where torque and acceleration are critical for off-road or track use.

*Pro Model torque exceeds industry standards by 25% due to optimized turbocharging and valve timing.
