recently hosted a drag strip race against its Ford
rivals to demonstrate a new diesel
and transmission powertrain. In an old airstrip up in Beiseker, Alberta, Canada
, 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 Chevrolet
Silverado. The Ford truck
was an F-250
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 Chevy's
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.
