2015 GMC Canyon gets the party started [w/video]

The 2014 Detroit Auto Show press days officially kick off tomorrow, but the night before all the madness commences, General Motors drove its new 2015 GMC Canyon pickup truck out for all to see. To refresh your memory, the Canyon is GMC's new midsize pickup - essentially a re-skinned version of the Chevrolet Colorado that debuted at the LA Auto Show in November.
Many of us at Autoblog prefer the look of the larger GMC Sierra to that of its Chevy Silverado kin, and we're having similar feelings about the new Canyon, especially after seeing it in person. It's sort of a pint-sized version of the Sierra, and it looks great. Clean lines are found throughout, and the Canyon's styling is decidedly premium.
At launch, the Canyon will be offered with the same engines as the Colorado - a 2.5-liter inline four-cylinder engine with 193 horsepower and 184 pound-feet of torque on the base end, and a larger 3.6-liter V6 with 302 hp and 270 lb-ft as an option. The Colorado's 2.8-liter diesel inline four-cylinder will be available after launch. Both two- and four-wheel drive configurations will be available, depending on the model.

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.

GM appears to repurpose Saturn Outlook parts on new Acadia

General Motors unveiled the company's refreshed GMC Acadia at the 2012 Chicago Auto Show yesterday, and if you were paying attention, you may have noticed something curious about the vehicle. While the new Acadia looks considerably better than its predecessor, a few components of the design looked more than a little familiar. Upon closer observation, it appears that GM has simply repurposed elements of the now defunct Saturn Outlook crossover on the 2013 Acadia. Both vehicles seem to share the same wrap-around rear glass, back hatch, tail light openings and exaggerated, squared-off fender arches.
While the vehicles are differentiated by badging, tail lamps and a rear valance, there's no denying the similarities toward the vehicle's rear. Up front, both share similar fenders, though adjustments have been made for the varying headlight designs.
That's good news if you just can't imagine life without the Saturn Outlook.
