GM's fullsize SUVs boost highway mileage by nearly 10 percent

We met the redesigned 2015 versions of the Chevrolet Suburban and Tahoe, and the GMC Yukon and Yukon XL at the 2013 LA Auto Show. Improved gas mileage numbers have been announced to go along with the improved exteriors and interiors, with city mileage improving by seven percent and highway mileage going up by nearly ten percent; you'll now get 16 miles per gallon in the city and 23 on the highway.
The only applies to models with the 5.3-liter engine, though, not the premium Yukon Denali and Yukon XL Denali SUVs with the 6.2-liter motor. Still, the 5.3 gets you more power than previously, with 355 horsepower and 383 pound-feet of torque underfoot, on top of the improved fuel economy numbers. The 6.2-liter sticks with official mpg ratings of 15 highway, 21 city. There's a brief press release below with words straight from the horse's mouth.

GMC Terrain Nightfall Edition is murdered-out for the masses

We've lost track of how many special edition Chevrolet Silverado and GMC Sierra pickups there have been over the past few years. But while some special editions can be kitschy, there's nothing overtly bad about the GMC's Nightfall line. We've already seen the blacked-out look on Canyon Nightfall and Sierra All Terrain X pickups, and now, it's being applied to the Terrain. As with the trucks, the Terrain Nightfall's changes are simple: the chrome-heavy finish is replaced with gloss-black accents where applicable. That's what you'll find on the grille surround, the front and rear fascia accents, the license-plate surround, mirror caps, and roof rack. Like Jay Z said, all black everything. Except for the wheels, of course – those have machined faces with black spokes. The grille inserts aren't strictly black either (they're charcoal), and as counterintuitive as it may seem, owners can choose from three body paints in addition to Onyx Black (Summit White, Graphite Gray, and Crimson Red). The Terrain Nightfall Edition will be offered on the SLE-2 and SLT trims, with prices to be announced closer to its fall 2016 on-sale date. GMC Introduces 2017 Terrain Nightfall Edition The News Ahead of its debut at the New York International Auto Show, GMC today introduced the 2017 GMC Terrain Nightfall Edition – a stylized special edition combining blacked-out exterior details and wheels, with popular technologies such as IntelliLink with available 4G LTE connectivity and Wi-Fi hotspot. It joins the Canyon Nightfall Edition and the all-new Sierra All Terrain X as the latest GMC vehicle to offer an exclusive, personalized appearance with the Terrain's premium features and refinement. Product Details The Terrain Nightfall offers an edgy appearance with 18-inch machine-faced aluminum wheels and gloss black spokes, a charcoal grill with a gloss black surround and accents, gloss black front and rear fascia accents, gloss black rear license plate surround trim, gloss black outside mirrors and black luggage rails. Terrain Nightfall Edition will be offered on SLE-2 and SLT models with four exterior color options: Summit White, Onyx Black, Graphite Gray Metallic and Crimson Red Metallic. On Sale Fall 2016 Quotable "Building on its best year ever, Terrain continues to attract new and style-conscious customers to GMC," said Duncan Aldred, vice president of GMC Sales and Marketing.

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.
