2023 GMC Canyon with ZR2-style off-road suspension caught in spy photos

GMC appears to be testing its redesigned 2023 Canyon pickup with an updated suspension lifted from the ZR2 variant of its Colorado twin. This heavily camouflaged prototype packs what look like Multimatic's DSSV dampers disguised with a black vinyl wrap.  Rumors have pointed to a GMC variant of the Colorado ZR2 since the midsize pickup adopted the AT4 branding for its off-road variant. GM appears to be ready to adopt the formula for GMC's more-upscale pickup as it has for the Silverado. The latter, which has now been officially confirmed, has been spied on the road with its own DSSV shocks disguised in the same fashion as those seen here. This prototype is riding high – even for an AT4 – and sports a set of knobby Goodyear Wrangler all-terrain tires. We can tell that this is a Canyon rather than another Colorado thanks to the GMC-style fog lamp design, which differs from the Colorado prototypes we've already seen testing. Like the Colorado, the redesigned Canyon is expected to be offered with just one engine: a 2.7-liter turbocharged four-cylinder lifted from the Silverado and Sierra pickups.  Look for the Canyon to debut alongside its Chevy twin sometime in the next year or two as either a 2023 or 2024 model.  Related video: This content is hosted by a third party.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Chevy Express 1500, GMC Savana 1500 get the axe

Fans of truck-based, light-duty vans can officially pour one out for the Chevrolet Express 1500 and GMC Savana 1500, as General Motors has officially put its long-serving big/little rigs out to pasture. Things aren't quite as sad as they sound, though. The heavier-duty 2500 and 3500 vans will soldier on, in order to duke it out with the largest members of Ram ProMaster, Ford Transit and Mercedes-Benz Sprinter families.
The move does seem to make a lot of sense. According to GM, customers only purchase the 1500-spec Chevrolet 23 percent of the time, while the GMC captures a mere 7 percent of the Savana family's sales. With numbers like that, it's no shock that GM thinks it can shift some of its buyers into its van family's more capable variants. "We knew we could move a lot of our 1500 customers into 2500-series territory," said GM's Joe Langhauser, the product manager for the company's full-size vans.
It's not just simple sales figures dictating the move, though. The 1500 line is taking up some valuable factory space that will be better spent on an eagerly anticipated new product.
