2015 Chevy Canyon, GMC Colorado to net up to 27 mpg with 4-cylinder

Before even officially going on sale to customers, the GMC Canyon and Chevrolet Colorado midsize pickup twins are already proving to be a success with dealer orders exceeding original projections. Now, there is even more good news for these siblings, with the fuel economy for their four-cylinder engines netting class-leading numbers and the 3.6-liter V6 getting segment-best payload ratings.
The 2.5-liter four-cylinder in the two trucks makes 200 horsepower and 191 pound-feet of torque, and in rear-wheel drive and six-speed manual trim it has an EPA rating of 19 mpg city, 26 mpg highway and 22 mpg combined. Opting for a two-wheel drive configuration with the six-speed automatic bumps those figures slightly to 20 mpg city, 27 mpg highway and 22 mpg combined. Finally, a four-wheel drive model with the automatic 'box carries a 19/25/21 rating. Those numbers are a tick better here and there compared to what's offered by the optional V6.
The twins' major four-cylinder, midsize pickup rivals are the Toyota Tacoma and Nissan Frontier, but they're both getting somewhat long in the tooth. To compare fuel economy and power, a two-wheel drive Tacoma with its 2.7-liter four-cylinder is rated at 159 hp and 180 lb-ft, and achieves 21/25/22 mpg. The Frontier with its 2.5-liter four-cylinder is good for 152 hp and 171 lb-ft, and carries 19/23/21 mpg figures.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

GM hard at work on Chevy Silverado and GMC Sierra PHEV pickups

Autoweek heard from sources at General Motors and Ford about how each automaker is addressing the dip in EV enthusiasm and sales. At General Motors, AW reports, "plug-in hybrid versions of the Chevrolet Silverado and GMC Sierra are headed to market, in a hurry." The sources gave no timeline for when the trucks might appear. GM CEO Mary Barra told analysts during GM's Q4 2023 earnings call, "Let me be clear, GM remains committed to eliminating tailpipe emissions from our light-duty vehicles by 2035, but in the interim, deploying plug-in technology in strategic segments will deliver some of the environmental benefits of EVs as the nation continues to build its charging infrastructure."  It's too soon to predict how the Chevy Silverado EV and GMC Sierra EV will fare on the market, the Silverado EV Work Truck still the only one available to customers. It might be better for GM if they're not too popular at first, the automaker's cautious EV production ramp-up and recent software setbacks responsible for some still-healthy reservation rolls. Barra said the company plans to build between 200,000 and 300,000 EVs, this year, which would clear that backlog. Heading into the end of February, with the Chevy Bolt out of the picture and additional EV pickup production pushed to 2025, our Spidey senses feel those are optimistic numbers. The Chevy Bolt was the third-best-selling EV in the U.S. last year, at 62,044 units. GM didn't have another vehicle in the top ten. Furthermore, the combined sales of every EV in the top ten after the Bolt — seven models from six manufacturers — is only just over 200,000 units. The Blazer EV and Equinox EV could make it happen, but there's no way Chevy wants to rush those, the Blazer EV still in software purgatory.   The report speaks of collateral damage, GM said to have canceled an electric pickup sized below the Ford Maverick and Hyundai Santa Cruz. Automotive News said it saw the truck in January 2023, describing it as a futuristic two-door with a low roof and a 4.5-foot cargo bed. A new full-size van program supposedly got the axe as well, eliminating the plan to put a new Chevy Express and GMC Savana on a Brightdrop EV chassis. Over at Ford, AW says its sources mentioned another canceled midsizer; Ford's apparently stopped working on an EV pickup sized a bit below the Nissan Frontier.
