recently hosted a drag strip race against its
rivals to demonstrate a new
and transmission powertrain. In an old airstrip up in Beiseker, Alberta,
, the world’s largest automaker showed off its new 6.6 litre turbodiesel V8 Duramax engine with 360 hp and 650 lb-ft of torque contained in a
with a 6.0-litre V8 pumping 325 hp and 570 lb-ft of torque, while the Dodge Ram had a 5.9 litre turbodiesel engine that produced 325 hp and 610 ft-lbs. of torque. All vehicles were automatics and each hooked to an equipment float holding a 3,200-kg (over three tons) tractor.
The Silverado won the race, followed by the F-250 and the Dodge Ram. While the
extra oomph no doubt played a part in its victory, the writer rightly attributes the win to the Silverado’s new six-speed Allison transmission that kept the pickup in its powerband's sweet spot more often that its rivals with traditional four-speed autos.
