What is the point of comparing engine torque anyway? Power matters. Not only peak power, but the entire power graph. Torque is a meaningless figure for car performance unless you know the RPM, so you can compute the power. Torque is interesting when selecting dimensions inside the gearbox, though.
If you doubt what I say here, think about what the gearbox does to the torque. The power tells you how much torque there is left at the wheels at a given speed, which is what counts. The torque at the engine tells you nothing about how the car will perform.
100 hp at 2000 RPM and 100 hp at 4000 RPM will perform the same way.
100 Nm at 4000 RPM will perform a lot better than 100 Nm at 2000 RPM, since it equals twice as much power.
