Nissan z 332 horsepower and 270 lb-ft of torque


Can someone give me a simple explanation of why two engines have the same horsepower and different torque?
Horsepower is a product of torque and rotational speed (RPM). So if the engines have different torque curves the horsepower could be different. The equation is: HP = Torque x RPM ÷ 5252

So the genesis makes higher torque at lower RPM compared to the Z.
