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.

GMC Hummer pickup and SUV previewed in video, set to be revealed in fall

GMC has just provided us with our first good look at the upcoming Hummer EV pickup and SUV. A video was posted online previewing the two models that also happens to feature LeBron James. From clay sculptures to prototypes in various levels of completeness, GM is allowing the world a sneak preview of what’s to come. A couple of the more revealing images come in silhouette photos of both the truck and SUV at the end of the video. The truck has a big four-door crew cab and an exceptionally small bed behind it. The angle from cab to bed is also notable. ItÂ’s not easy to see exactly whatÂ’s going on since itÂ’s shrouded in darkness, but when we saw the Hummer pickup, it was rocking sail panels that resemble the ones on the truck weÂ’re looking at. The truckÂ’s general shape is off-road oriented with squared-off, sharp lines tracing the entire silhouette. Its big, knobby tires and blocky wheels are clear indicators of what GM was aiming for with this electric pickup. As for the SUV, comparisons to the Ford Bronco four-door will be inevitable. If our eyes are picking up the scale of this photo correctly, though, the Hummer SUV appears to be a slightly larger vehicle than the four-door Bronco is. Although, the wheelbase for the SUV is shorter than that of the Hummer truck. ThatÂ’ll help it off-road. Those small bumpers and short overhangs along with the bumper cutouts should be hugely beneficial to approach and departure angles, as well. Hummer EV prototype View 6 Photos GMCÂ’s shots of the Hummer in the studio are equally as revealing. We can see what looks to be an intense front skid plate and two big tow hooks. In addition to the off-road gear, GMC has allowed a look at the frunk. The front “grille” is one piece with the hood of the truck, so the whole assembly pulls up. That makes for what appears to be a very easy-to-load front trunk compared to other EVs that force you to lift items up and over the front of the car. The whole removable roof assembly is exposed in this video, too. We can see the crossbars that the removable panels attach to and also what the truck looks like with the tops removed. The SUV appeared to have removable roof panels from our short glimpse of it in a studio awhile back. Other new details GM mentioned in the video include Adrenaline Mode, Crab Mode and Next-Gen Super Cruise. We donÂ’t know what Adrenaline Mode or Crab Mode do yet, but theyÂ’re certainly off-road modes that GM has designed specifically for this electric Hummer.

Wards names its 2015 10 Best Interiors list

Wards Automotive has named the winners of its 10 Best Interior awards, covering a wide but affordable array of vehicles. Where last year's list contained two six-figure vehicles, including the $372,800 Rolls-Royce Wraith, this year's is, well, a whole lot more reasonable. The publication lists the Mercedes-Benz C400 at $65,000 (which seems off), making it the most expensive vehicle here. That said, we'd argue that the entire C-Class line deserves to make this year's list, owing to its varied and high-quality selection of materials. The other vehicle to break the $60,000 mark, meanwhile, is the $60,675 Ford F-150 King Ranch, which has 327,000 pounds of leather lining its interior. Only one other German car, the BMW i3, and one other pickup truck, the GMC Canyon, managed to make this year's list. Here's the full list of this year's winners: 2014 BMW i3 ($52,550) 2015 Chrysler 300C Platinum ($51,175) 2015 Ford F-150 King Ranch ($60,675) 2015 GMC Canyon SLT ($40,465) 2015 Honda Fit EX-L ($21,590) 2015 Jeep Renegade Limited ($33,205) 2015 Kia Sedona SXL ($43,295) 2016 Mazda6 Grand Touring ($33,395) 2015 Mercedes C400 ($65,000) 2015 Nissan Murano SL ($41,905) See what we mean about the mainstream vehicles? Not only is there a distinct lack of luxury brands, it's the price of some of the vehicles that surprise. The Honda Fit, Jeep Renegade and Mazda6 are very reasonably priced, especially when you compare Wards price with the starting price. The Renegade Limited starts at less than $25,000, the Mazda at less than $22K and the Fit at under $16,000. Head over to Wards for a more detailed explanation of why each vehicle won.
