Chevrolet has recently confirmed that the U.S. Environmental Protection Agency has given its Certificate of Conformity to the 2016 Colorado Duramax diesel. According to the company, EPA said that there were no issues or any concerns revealed during the evaluation and testing of the Colorado Duramax’s emission control system.
For the two-wheel drive turbo-diesel, EPA estimates that it has a highway fuel economy of 31 mpg and therefore, this makes it the most fuel efficient of pickup trucks in the U.S.
The four-wheel drive meanwhile has a highway fuel economy of 29 mpg. In addition, since the two-wheel drive has a fuel tank that can carry 21 gallons, it can go as far as 651 miles on a full tank.
Director of Chevrolet Truck Marketing Sandor Piszar shares that the Colorado Duramax is truly in a class of its own. Piszar adds that with the Colorado gas model already leading the segment in terms of fuel efficiency, the diesel model is expected to give competitors a run for their money as it allows customers to go where they want with lesser fill-ups.
Chevrolet discloses that the two-wheel drive diesel has an EPA estimated rating of 22 mg city and 25 mpg when combined. The four-wheel drive, on the other hand, carries a 20 mpg city rating and 23 mpg when combined.
Complementing the already efficient fuel economy is its maximum trailering ratings. The four-wheel drive version can pull up to 7,600 pounds or about 3,447 kilograms while the two-wheel model is capable of pulling up to 7,700 pounds or around 3,492 kilograms.
The 2016 Colorado Duramax has the turbo-diesel 2.8L Duramax engine, capable of giving 181 horsepower, or about 133 kW of power. Maximum torque meanwhile is at 500 Nm or 369 lb.-ft. The high performance engine is then partnered with the six-speed Hydra-Matic 6L50 automatic transmission.
Unlike in other models, this particular transmission has a Centrifugal Pendulum Vibration Absorber that is located in the torque converter allowing the car to lessen both the noise in powertrain and the vibration. Adding to all these features is the variable-geometry turbocharger which optimizes the power within the rpm band as well as boosts its efficiency. It also has a balance shaft that allows for smoother driving.
Chevrolet has guaranteed that the diesel engine of the Colorado is B20-capable. There are however two new features that are sure to give drivers more confidence and control. The first is the smart diesel exhaust braking which improves vehicle control.
It also lessens the brake wear since it reduces the need to break when on a downgrade. The second is the integrated trailer brake controller which works in conjunction with the Colorado’s antilock brake system. This combination gives the Colorado a measured brake force thus removing the need for any aftermarket brake controller.
Colorado diesel will be sold starting this fall and customers will have a choice of getting it in either the LT or Z71 Crew Cab models. Both will be available in either the two-wheel or four-wheel drive version. The diesel option is priced $3,730 higher than a 3.6L V-6 engine model with similar equipment.
