Duramax 2.8L Diesel Engine

General Motors has announced that it has incorporated the Duramax 2.8 liter turbo diesel engine in to its 2016 Chevrolet and GMC Canyon trucks.  In addition, General Motors has announced that the EPA has certified the trucks for getting 31 mpg on the highway.  On November 17, Engineering News Record reported that the engine is a four cylinder diesel and generates 181 horsepower and 369 foot pounds of torque.  In addition, two wheel drive vehicles equipped with six speed transmissions will get EPA estimated mileage rates of 22 mpg in the city and 25 mpg in combined driving.  For those interested in four wheel drive vehicles, the mileage rates are 20 mpg in the city, 29 mpg on the highway and 23 mpg in combined driving.

Duramax was created in 1998 as a result of a joint venture between General Motors and Isuzu to manufacture diesel engines.  Specifically, the goal was to manufacture the first high pressure, common rail, direct injection engine.  Prior to the Duramax engine, GM used an engine that was made entirely of iron in a V-8 configuration, was of the indirect injection type, took up 6.5 liter, rated at 215 horsepower and 440 foot pounds of torque.  For the most part, GM began installing 6.6 liter diesel engines in some of the full size pickups back in 2001.  As the demand evolved, so did the engine.  From 2001 until the present, there have been 5 variations until now when the 2.8 liter engine has been introduced into the midsize truck range.
