Inside the G90 / Powertrain edition〉 3.5 turbo 48V electric supercharger that enhances the leisurely power performance of the flagship sedan
Genesis G90 LONG WHEEL BASE (long wheelbase) is equipped with a new heart, a 3.5 turbo 48V electric supercharger, further strengthening the dynamism befitting a flagship sedan. Introducing a 3.5-turbo 48V electric supercharger that has been optimized for performance through a 48V battery system.
A leisurely performance powertrain is very important for luxury brands. This is because luxury cars are often large and heavy, so they must have performance appropriate for this. In particular, the flagship sedan requires a higher level of powertrain perfection as it has to overcome these conditions and realize a relaxed and stable driving sensation.

In addition, the rapidly changing external environment for internal combustion engines increases the need for advanced engine technology. This is because powertrain trends are rapidly changing due to strong environmental regulations implemented in major advanced countries.
Recently, instead of high-power engines that are less environmentally friendly, engine technology that considers both performance and efficiency is emerging. Among them, the 48V battery system is a representative technology that meets this condition.
The Genesis G90 long wheelbase is newly equipped with a 3.5 turbo 48V electric supercharger and provides differentiated dynamism and a luxurious experience in every process of occupant movement. The 3.5-turbo 48V electric supercharger is a next-generation powertrain that pursues 8-cylinder engine-level output and improved efficiency through a 48V battery system.
The maximum output of the 3.5 turbo 48V electric supercharger is 415 horsepower (PS), and the maximum torque of 56.0 kgf.m is uniformly realized from 1,300 rpm to 4,500 rpm. Compared to the V8 5.0L GDI of the first generation of the Genesis G90, the torque is improved by up to 35%. What technologies and principles are hidden behind this relaxed performance?
The 48V MHSG is a system that integrates a starter motor and an alternator (generator) and plays various roles in the driving process. Typical examples include the regenerative braking function that recovers kinetic energy wasted during deceleration and the extended ISG (Idle Stop & Go) function that improves efficiency by turning off the engine before the vehicle comes to a complete stop. Unlike general ISG, Extended ISG is a control function that further minimizes fuel consumption and emissions by stopping fuel injection during deceleration as well as at a stop
