Power output characteristics
Low-speed torque optimization: Through the HX60 dual-flow turbocharger, the torque reaches 2850 N·m at 1300 rpm, which is 18% higher than the same displacement model.
Fuel economy: Full-load fuel consumption rate is 82 L/h, which is 14% lower than the traditional 700 HP model.
Twin-scroll turbocharger: Using Holset HX60 dual-flow supercharger, the boost pressure is increased to 4.5 bar, and the low-speed torque is increased by 18% compared with M3.
Nano-coated piston: The top surface of the piston is sprayed with CrN-Al2O3 composite ceramic layer, with a temperature resistance limit of 550℃, supporting continuous 12 hours of 100% load operation.
