Two years ago, General Motors announced the redesigned version of the GMC Canyon and the Chevrolet Colorado. After two years, the midsize pickups are getting a diesel option as well.

Previously, the two vehicles were available in the V6 model, but now they will get a Duramax Diesel engine as well.

The 2016 Chevrolet Colorado and GMC Canyon will be available to buyers starting from this fall. The new engine will be a 2.8 liter Duramax turbocharged engine that produces 181hp at 3,400 rpm. The pickups will be equipped with a six-speed automatic gearbox, which is the only choice. Their maximum trailering has been upped to 7,700 pounds for 2WD trucks and 7,600 pounds for 4WD trucks.

The price of the two pickups with diesel engine is higher than the V6 gasoline model. The Chevrolet Colorado costs $33,520 for the entry model, while the GMC Canyon starts at $34,875. Both trucks come with a standard trailering package which features automatic locking rear differential, 3.42 rear axle ratio, seven-pin connector and much more.

General Motors is yet to share the fuel numbers, but the wide assumption is that the Duramax diesel engine will make both pickups more fuel efficient. At the moment, the trucks can go 27 miles per gallon on the highway and the diesel engine is expected to up that number to 30 miles per gallon. The Duramax diesel engine can run up to 20% biodiesel. Some added features are the centrifugal pendulum vibration damper.

The list of features for the Duramax diesel engine includes: oiling circuit, including a dedicated feed for turbocharge, which increases pressure at the turbo resulting in faster oil delivery, 16.5:1 compression ratio, iron cylinder block, forged steel crankshaft, connecting rods, piston-cooling oil jets, laminated steel oil pan contributing to better rigidity and quietness of the engine, common rail direct injection fuel system, balance shaft for better smoothness (the balance shaft also drives the oil pump).

Apart from changing the engine of the vehicles, everything else stays the same. There are some new tech features such as Apple CarPlay, which is a new interface mirroring the iPhone’s functionality. Next year, the Android Auto is expected to make its way to the vehicles. Another tech feature by Apple is the Siri Eyes Free, which is a feature that integrates the voice controls of the iPhone with the pickup. Text message support is also available.
