Towing and hauling
One of the biggest assets of a diesel engine is its ability to lug a load.
A couple of years ago I had a yarn with Dr Wolfgang Warnecke, the chief scientist for Shell’s global mobility fuels division.
Aside from being a Unimog tragic, he also had some interesting things to say about diesel engines.
“As far as thermal efficiency under load is concerned, there’s nothing better than a diesel engine,” he said.
“Light vehicle fuels may change in the future, but in heavy commercial applications nothing comes close to a diesel.” We then spent a lot of time waffling on about Unimogs and hunting. The Y62 Patrol has a decent 7000kg GCM which makes it a walk-up start for tow applications.
However, it would be fair to speculate that, while it will haul a load effortlessly, the Nissan will no doubt drink a lot of juice to do it with peak torque so high in the rev range. The fuel gures quoted in this story are based on a loaded wagon tipping the scales at about 3000kg.
