There is confusing info on the HP ratings for the E350 and E450 for the new 2024 MY. Online in many review videos you will hear that the E350 has 255hp and the E450 has 375hp. However in the order guide it says that the E350 is 255hp (ICE), 23hp (ISG) and the E450 is 375hp (ICE), 23hp (ISG). Is the ISG power added to the ICE to be a combined total of 278 and 398 hp respectively? Does anyone know how the ISG rating factors in with the ICE rating for both hp and torque?

Horsepower and torque are rated at their peak RPM, which is far higher up the rev range than the electric motor’s operating window.

The electric motor boosts low RPM power/torque.
