The 3.5 Turbo 48V Electric Supercharger Engine is a notable advancement that overcomes the limitations of traditional engines by integrating a 48V battery system for enhanced efficiency, eco-friendliness, and performance. The electrified powertrain system includes a 48V electric supercharger, 48V Integrated Starter Alternator (48V MHSG), a 48V LDC integrated battery system, and a water-cooled large-capacity intercooler. The electric supercharger, working in conjunction with the turbocharger, delivers rapid boost pressure even at low RPMs below 1,750, ensuring smooth output and torque across all ranges. The engine boasts a maximum output of 415 horsepower, 35 horsepower higher than the standard 3.5 turbo engine. Its maximum torque range is the same at 1,300-4,500 RPM, but with an increased torque of 56 kgf·m. The thermal efficiency is improved by up to 8.4% compared to the V8 5.0 GDI.
