In the above graph, the N54 has a slight advantage in peak output with regard to horsepower. Since the N54 is a turbocharged engine, the output torque figures show the torque output at a lower engine speed, but it is quite "flat" up to almost 5000 RPM.

In contrast, the diesel has a much higher torque output, but is only available for a short time. After about 2400 RPM, the torque drops off considerably.
