I guarantee that the 69BHP is high in the RPM range. It could produce 100lb-ft from 2000rpm-3500rpm and still have a 69BHP peak.

Remember, diesels have a very linear low end, and drop off quickly at high rpm. You just have to drive it differently.

The 1.9L TDI from the mk4 volkswagens had a peak hp of 90, but produced a peak torque of 155lb-ft.
