2018 CTKC Pickup Truck Fuel Economy Report Has Unexpected Result

2018 CTKC Pickup Truck Fuel Economy Report Has Unexpected Result

Each year the Canadian Truck King Challenge does what we call “real-world” fuel economy testing.  But, what does that really mean?  And how does it differ from what the government does?

Well for starters, the government tests in a laboratory.  New vehicles are mounted on a two-wheel chassis dynamometer which simulates on-road driving to measure fuel consumption.  The computer that controls the test is pre-programmed to take into account the particular characteristics of the test vehicle.

Each vehicle is then taken for a “simulated” drive.  Once the trip is complete it is repeated after the vehicle has been shut-off for eight minutes and both results are recorded.

The Truck King “real-world” method is the polar opposite of this. Each one of our trucks is driven empty on-road, with a trailer behind it and hauling payload; in other words, they are treated exactly how an owner treats them.  We repeat a set loop over and over – but changing up drivers each time, which adds another point to this real-world operation.  The numbers we produce are then a result of these tests. 

All results are measured using a FleetCarma C5 logger. These units plug into the OBD port of the vehicles and obtain both standard and proprietary signals required for energy analysis.

This is the fifth year we have produced the real-world fuel report.

WHAT WE FOUND

In the half-ton category, we had a result we’ve never seen before. The 2018 Toyota Tundra with its 5.7-liter V8 managed to be the most efficient truck in every category. The Nissan Titan is managed to be the second most efficient pickup, while the domestic three all fell within one L/100km of each other.

For the three-quarter ton trucks, the results were mixed. Sadly, our test unit experienced a malfunction and as a results much of the Chevy 2500’s information was not logged. In the empty category, the Chevy 2500 ended up being the most efficient, while the Ram ended with the lowest average fuel economy.
