GM CEO Barra says 'we are selling every truck we can build'

DETROIT — General Motors Chief Executive Mary Barra said on Monday the automaker is "selling every truck we can build" and expanding North American truck-building capacity, even as U.S. gasoline prices hit record highs. Barra made her comments during the automaker's annual shareholder meeting. GM is pursuing a two-track strategy: Investing heavily in electric vehicles for North America, China and other markets, and funding those investments by trying to maximize profits from its North American combustion pickup truck and large SUV lineups. Barra said GM is planning higher-priced versions of its Silverado large pickup and its large SUV models. GM and its Detroit rivals Ford Motor Co and Stellantis NV rely heavily on sales of large pickup trucks and SUVs for global profits. High U.S. gasoline prices in the past have undermined consumer demand for relatively inefficient models. Nominal pump prices hit an average of above $5 a gallon for the first time ever last week, the federal government said Friday. GM is ramping up production of EVs. Barra said the Cadillac Lyriq electric sport utility is sold out through 2023. In response to shareholder questions, Barra said the "clear priority" for using cash generated by its operations is to "accelerate our EV plans." She did not rule out share buybacks or other approaches to returning cash to shareholders. GM still expects to increase production this year by 25-30%, despite continuing pressure on semiconductor supplies globally. Barra said GM is working to redesign vehicles to reduce the number of processors required by 95%. Barra serves as GM's board chair and CEO. GM shareholders overwhelmingly rejected a proposal to separate those roles.

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.

2015 Chevrolet Silverado 1500 Custom Sport Quick Spin

Coincidentally, the week we had the 2015 Chevrolet Silverado 1500 Custom Sport a friend asked, "What would you buy if you could only have one vehicle for everything?" After a week's driving and trailer hauling, very close to first choice would be an American pickup. They're all so good now, you can't lose. And as we found in the Chevy you can go anywhere and haul anything, and you pay no penalty for capability until you try to find an open space on the street to park. Nicely equipped versions like the Custom Sport aren't cheap, but if you need a truck and you like the look of this one, it is really good. Driving Notes The cabin is big and inviting, and everything in it is big and inviting. The materials are nice enough to look and feel swanky but not so lavish that you're afraid to get them dirty. The seats are sized for adult male bears but they don't swallow you up. The sunroof is big enough to be an observatory. It's also quiet. The only time it gets mildly unruly is when you call for power and the engine has to downshift a few gears, otherwise you don't hear the exhaust unless you roll down the window. It looks like it was designed with a T-square. I quite like it, the body-colored bumpers toning things down, the 20-inch wheels doing a much better job of filling those ample arches than the standard 17-inchers. The truck is built for people who take their work and all their gadgets with them. The front console has three USB ports, two 12-volt cigarette lighter ports, and a three-prong 110-volt outlet. The giant cubby at the base of the console has an insert to hold a clipboard or a small tablet. The abyss under the center armrest has one more 12V cigarette lighter, two more USB ports, an SD card reader, and another specialized holder for something the size of a small tablet. There's a WiFi hotspot so the streaming never has to stop. The Chevrolet navigation was trouble-free as usual, and you can input destinations on a QWERTY touchscreen keyboard. Every nav system should be so solid. The Silverado has some of the best feature implementations we've encountered in any vehicle. The lane departure warning and park assist systems don't vibrate the steering wheel, they vibrate the seat. The left, right, and middle of the seat bottom will pulse as necessary, an intuitive, peripheral way to deliver a message that doesn't interrupt your primary focus. The rear-view camera is no longer offset, it's centered.
