Sierra 3500 HD Crowned 2015 Canadian Truck King
The 2015 GMC Sierra 3500 HD outscored all other HD trucks in the annual Canadian Truck King Challenge.
Sierra was pitted against the Ford 350 and Ram 3500 in a gruelling two-day test held in London, Ontario that measured toughness, fuel economy, towing ability and overall comfort.
For the first test, the trucks were first equipped with a fifth-wheel hitch and required to tow a 15,000lb RV trailer over a 300-km route. Next, the fifth-wheel was removed and each truck was loaded with a 3,000lb payload of roofing shingles and driven another 200-km test track. The trucks were even raced down a quarter mile drag strip.
After all was said and done the Sierra 3500 was praised for its road-manners, do-it-all capability, and combination of interior amenities and smart-shifting Allison 1000 six-speed automatic transmission.
Other Highlights Include:
- 397 horsepower (296 kW) at 3,000 rpm
- 765 lb.-ft. of torque (1,037 Nm) at 1,600 rpm
- High-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions
- Exhaust brake system that enables controlled vehicle slowdown on downhill grades without actuating the brakes
- Selective catalytic reduction after-treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance.
- Best-in-class maximum payload of 3,508 kilograms (7,374 lbs)
- Best-in-class conventional towing capacity of 8,890 kilograms (19,600 lbs)
