Was driving my savana 2500 with the 2.8 duramax and noticed white smoke in the rear view mirror. Pulled over and saw it was coming from under the hood and diesel was leaking out under the engine. Got towed to the dealer as it’s under warranty and they said it’s missing a fuel line clip on the line between the high pressure pump and the fuel rail. Part number 55499116. Anyone else experienced anything like this? The clip is on order arriving today but if it’s the actual fuel line the part is on backorder and it could be weeks..... Apparently it’s not interchangeable with the Colorado/canyon fuel lines and not many vans with the 2.8 out there. Thanks, Shane

Zane: The 2.8L Duramax is an engine that will extend the capability of the Colorado and Canyon to within a stone's throw of the full-size Silverado and Sierra. From the moment you turn the key, there’s no mistaking this as a diesel engine. Noticeably louder than GM’s other gas engine offerings, owners will probably enjoy that their pickup sounds remarkably similar to the bigger 6.6L Duramax V8. In our short drive time we were impressed by the massive amounts of low end torque for a vehicle of this size. 369 lb-ft of torque at only 2,000 rpm goes a long way. However, with only 181-horsepower, the Canyon 4x4 crew cab we drove didn’t feel as quick as its 3.6L gas-powered counterpart. Point the nose of the GMC up a steep hill and the Duramax diesel’s benefits are immediately apparent. Nothing is going to stop this truck once it gets moving and you feel like the hand of God has your back. Acceleration is smooth and linear through the entire engine range. That’s the experience diesel truck buyers want and GM has given it to them. Bolder, louder and purposeful in nature. Oh and did we mention fuel economy? Prepare to be impressed. We saw over 30 mpg on our drive loop. GM executive Mark Reuss confirmed to us that the final EPA number should be very close to our results. That would place the Colorado and Canyon has the most fuel efficient trucks you could buy. No wonder GM is exploring options to increase the number of Colorado and Canyon it can build. John: What struck me first was the great look of the Canyon. Particularly from the front ¾ view. I had just left off-road testing in a 2016 Tacoma and in terms of looks, the Canyon wins hands-down. My tester was a $45,280 SLT Crew Cab with 4WD. Trucks are expensive now, but this one had it all. Premium Bose audio and Nav ($500), Spray in bedliner ($475) and Chrome assist steps ($725). I was impressed that the Canyon had Lane Departure Warning and Forward Collision Alert at no extra charge. That will cost you $500 on a Tacoma. The biggest single adder was the $3,730 Duramax engine. Although that buys a lot of gasoline, the Duramax has benefits beyond fuel economy to its fans. Hills surrounded the venue we were attending, and they were steep. Like Zane, I was immediately impressed by how strong the Canyon I drove felt. I too noted the fuel economy. Over the past 50 miles that it had been driven in rural NY the vehicle had averaged 22.2 MPG and its peak had been 34.5 MPG (according to the truck). Writers at this event were passing up track time in a Corvette to drive the Canyon on-road. It was one of the most popular vehicles at the event. The new Canyon and Colorado Duramax will not disappoint. GM is proud of this new truck, and as Zane’s interview with Mark Reuss proves, GM is looking hard for places to build more. The Canyon Duramax looks, drives, and acts like a winner.

Among the most interesting data is the official horsepower and torque figures for the engines, the estimated cost increase over the other models, and that the engine will only be available in crew cab configurations in LT and Z71 trim. The new engine will come paired to a Hydra-Matic 6L50 automatic six-speed transmission and comes with a special "centrifugal pendulum vibration absorber (CPVA) in the torque converter. Equipped pickups will also come standard with a Z82 trailering package, integrated electronic brake controller, a G80 automatic locking rear differential, and a 3:42 rear axle. The 2016 Chevrolet Colorado and GMC Canyon with the 2.8L Duramax turbo-diesel will go on sale this fall. GM claims it is the cleanest diesel engine ever produced by the company.
