GM promises to add 20 EVs and fuel-cell cars to lineup, paid for by SUVs

DETROIT — General Motors outlined plans on Monday to add 20 new battery electric and fuel-cell vehicles to its global product lineup by 2023, financed by robust profits from sales of gasoline-fueled trucks and sport utility vehicles in the United States and China. "General Motors believes in an all-electric future," GM global product development chief Mark Reuss said on Monday during a briefing at the company's suburban Detroit technical center. Future generations of GM electric vehicles "will be profitable," Reuss said, but added it was not clear when GM could make all its new vehicle offerings zero-emission electric cars. Regulators in China and some European countries have floated proposals to ban internal combustion engines by 2030 or 2040. "We will continue to make sure our internal combustion engines will get more and more efficient," Reuss said. GM shares were up more than 4 percent in midday New York trading on positive comments from Rod Lache, auto analyst at Deutsche Bank. Automakers, including electric vehicle market leader Tesla, lose money on electric cars because battery costs are still higher than comparable internal combustion engines. The company offered sneak peeks of three EV prototypes: a Buick SUV, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM funds its forays into new technology using a river of cash generated by old-technology vehicles popular with its core customer base in the United States heartland. In comparison, Tesla has burned through an estimated $10 billion in cash and has yet to show a full year profit. GM earned more than 90 percent of its $12.5 billion in pretax profits last year in North America, amid robust demand for its lineup of large sport utility vehicles and pickup trucks. The company's profitable operations in China rely on consumer demand for an expanding lineup of gasoline powered SUVs. GM has previously announced plans to make some of its future electric vehicles capable of driving themselves in robot taxi fleets. The company offered sneak peeks of three electric vehicle prototypes: a Buick brand sport utility vehicle, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM collaborated with Korean battery maker LG Chem to build the Bolt battery system. Company officials did not say what companies would supply batteries for the larger fleet of vehicles promised by 2023. Fuel-cell vehicles will also play a role in GM's future, the company said.

2022 GMC Yukon Review | AT4 and Denali make the strongest case

The total redesign of GM’s full-size SUVs for the last model year transformed every brandÂ’s version for the better, as the switch to an independent rear suspension resulted in the exact improvements weÂ’ve been wanting in terms of ride, handling, interior space and cargo capacity. Now in their second year of this generation, the 2022 GMC Yukon and Yukon XL continue to take advantage of these fantastic changes. Just as always, the GMC versions borrow heavily from their sister SUVs, the Chevrolet Tahoe and Suburban. The main differences lie in the exterior styling, and to a lesser extent, the interior. ThereÂ’s also the matter of price, as the Yukon is positioned in a slightly more premium space than the Chevy version of this truck. Most notable in this regard is the popular, top-of-the-line Denali, which has for the first time has an interior design that's different than other Yukons and every Tahoe. Despite this premium positioning, the Yukon is not prohibitively expensive, and it reasonably competes with other full-size SUVs like the Ford Expedition and Jeep Wagoneer. Which of the GM SUVs you choose is based almost entirely on looks and price, as the available feature set, engine lineup — we suggest the money-saving diesel — and drive options are nearly the same between them. ItÂ’s hard to go wrong, though, because just like last year, GMÂ’s full-size SUVs are our current leaders in the clubhouse as the ones to get. Interior & Technology   |   Passenger & Cargo Space   |   Performance & Fuel Economy What it's like to drive   |   Pricing & Features   |   Crash Ratings & Safety Features What's new for 2022? The most notable change for 2022 is a totally new infotainment system powered by Android Automotive. It brings new software and Google Maps as a native navigation system. Another tech enhancement is GMC swapping in its 12-inch digital instrument cluster (and making it standard) for the analog gauge cluster from last year. Lastly, the AT4 trim is now available with 6.2-liter V8 option. Note that GMC increased pricing for the Yukon mid-way through the 2022 model year. You may see differing prices online as a result, but those on this page are accurate as of May 31, 2022.  What are the Yukon interior and in-car technology like? The YukonÂ’s interior is an odd one, as there are two entirely different interior designs available depending on which trim you choose.

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.
