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.

Weekly Recap: Chevy and Alfa plot comeback strategies

Chevrolet and Alfa Romeo were two of the 20th Century's most iconic automotive brands. Chevy embodied America's post-war power and confidence. Alfa was the definition of the stylish Italian sports car. They reached halcyon heights in the 1950s and '60s, before declining precipitously amid new competition, changing consumer tastes, and uneven corporate management. Both say 2015 is the start of something better, and this week Chevy and Alfa laid out ambitious plans and showcased new cars that they hope will make them more relevant this year, and in the coming years. Each brand sits at its own crossroads, and their paths forward are as different as the Chevy Cruze and the Alfa Romeo Giulia. Chevy is still a sales beast, as evidenced by its volume of 4.8 million vehicles sold around the world last year. Chevy executives are fond of saying one of their cars is sold every seven seconds, which illustrates the strength and reach of a car brand that is the fourth largest in the world. "Make no mistake about it, we are a brand for the people," said General Motors North America president Alan Batey. But he wants consumers to want to buy a Chevy for its design and technology, not simply because it's affordable. That starts with all Chevys now featuring a distinctive a family look, with sporty cues from the Corvette or strong lines that riff on the Silverado pickup. "We want people to fall in lust with our cars," said Mike Pevovar, executive design director for Chevy passenger cars. "That initial emotional attraction has to be right on the exterior, and that's where form comes into play." Chevy is also loading up its cars, like the freshly unveiled 2016 Chevy Cruze, with technology to appeal to a younger crowd that prizes connectivity. The Cruze will offer Apple CarPlay and Android Auto with its MyLink infotainment system, and OnStar with 4G LTE and wifi. Seeking out younger buyers is also sound business practice: Millennials now outnumber Baby Boomers as the largest single age group in the United States. Younger buyers also can improve a brand's image, which is another area where Chevy would like to improve. Chevy ranks 82nd on Interbrand's Best Global Brand's list, behind 11 other automakers. Apple is No. 1. "We need our own variation of the Genius Bar," Batey said. 2016 Alfa Romeo Giulia View 3 Photos Meanwhile, Alfa is in different shape.

Recharge Wrap-Up: LAPD gets Zero MMX, Chevy's new inverter, Hyundai Tucson's new powertrains

Some police in Los Angeles will be riding Zero MMX electric motorcycles on duty. The LAPD is adding the fully electric police/military all-terrain bikes to its patrol fleet. According to Officer Steve Carbajal of the department's off-road unit, "It costs less than 50 cents to charge compared to using gallons of gas, maintenance is simple, and the community appreciates how quiet they are." The electric bikes, with their lack of noise and a headlight the rider can turn off, also have the benefit of stealth, giving the officers what Carbajal calls "an added tactical advantage." The MMX also has swappable batteries, is designed for quick ignition and has power reserve capabilities so the rider won't be caught with a dead battery while chasing down a perp.

Drivers of classic cars in Detroit were able to fill up their tanks at gas prices corresponding to their model year, thanks to a promotion by Hagerty Insurance for National Collector Car Appreciation Day on July 11. That meant prices from 21 to 90 cents a gallon, as the cars that showed up ranged from the years 1929 to 1989. That's about as affordable as charging your EV. Head over to Autoweek for more details and some photos from the event. The next-generation Chevrolet Volt will likely benefit from a new inverter being developed by General Motors. GM is about two-thirds of the way through the development of the new inverter, which should be ready in January 2016. The inverter, which has a peak output of 55 kilowatts a continuous output of 33 kilowatts, will be adaptable for use in other GM vehicles. Chevrolet is working to reduce the Volt's production costs by $10,000 per vehicle, which should make it more affordable, and the new inverter could help reach that goal should it make its way into the car.

"We are covering the waterfront on all alternative fuel strategies, from standard hybrid, to plug-in, battery-electric, and fuel cell," says Hyundai's US Chief Dave Zuchowski.
