For the second year in a row, the Ram 1500 EcoDiesel has taken the top spot at the Canadian Truck King Challenge. 

The EcoDiesel captured the win in the half-ton segment over the 2016 Ford F-150 and Chevy Silverado, successfully defending its title. A new testing process, in which the winner is invited back the following year to defend its title, began just this year at the Canadian Truck King Challenge, and the Ram took advantage.

The overall runner up and winner in the midsize truck category is the 2016 GMC Canyon Diesel.

For commercial vans, the 2016 Ford Transit claimed the win in full size vans while the new 2016 Mercedes-Benz Metris took the overall win in midsize vans.

The 2016 Canadian Truck King Challenge had a total of nine professional automotive journalists gather to evaluate each one of the entered vehicles over a two day period.

And Truck King is no beauty contest. Each half-ton pickup hauled 1,000 lbs. in its bed and towed a 6,000 lb. trailer, while the midsize trucks pulled 4,000 lbs. and also hauled 1,000 lbs. in the bed.

Each van was also tested with 1,000 lbs. of payload through tight city streets, so that they were used exactly as they would be doing a day’s deliveries.

As always, The Canadian Truck King Challenge strives to bring you the best real-world fuel economy numbers for new pickup trucks, and this year is no different. Each truck was attached to a data logger and all of the info is currently being deciphered by our tech wizards. Check back soon for the fuel economy report.
