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.

These are 2014's best-selling cars and trucks

Now that 2014 is no more than a set of numbers on spreadsheets, at last, the grist mill gets its first real load to chew on. The number one selling vehicle in America last year was the Ford F-Series, a fact that should surprise you only if your family name is Van Winkle and your naps tend to last 38 years, which is how long the Ford pickup has ruled our buying landscape. Even though series sales were down 1.3 percent, it still racked up 753,851 units. That's 2,065.3 sales per day, every day, all year. The Chevrolet Silverado, up 10.3 percent for the year, was still a daylight second at 529,755 units. The cab-and-bed love continued into third place with the Ram 1500-3500 trucks, gaining 23.6-percent year-on-year to clock 439,789 units. The robust turnout at The Bighorn and Jeep helped Fiat-Chrysler increase its sales by 16 percent, past the two-million mark. Our number one car? The Toyota Camry, staying in first place with a 4.9-percent sales boost to 428,606 sales, trailed again by the Honda Accord at number five with 388,374 sales. Accord sales rose six percent, and if it's any consolation to Honda for coming in second - not that it needs one - it is the only manufacturer to have three vehicles in the top ten. The rest of the list: the Nissan Altima with 335,644 sales (+4.7%), the Honda CR-V with 355,019 (+10.2%), the Toyota Corolla/Matrix combo with 339,498 (+5.9%), the Honda Civic with 325,981 (-3.1%), and the Ford Fusion with 306,860 sales (+2.9%). Total sales for the year were up six percent to 16.5 million vehicles, a volume not seen since 2006, aided by a strong December that was up by 11 percent year-on-year. Ford was the top selling brand overall but sales didn't really budge from 2013, while Subaru rocketed up 21 percent to finish with 513,693 sales. At the precious end, BMW, Audi, Porsche and Land Rover all had record years, and Kelley Blue Book thinks we could be looking at 17 million sales for the next two or three years.

First-edition Detroit muscle raises millions for charity at Barrett-Jackson

Amidst all the classic metal crossing the auction block each year in Scottsdale, AZ, Detroit automakers have a tradition of donating the first examples of their most enticing new muscle cars, with the proceeds of their sales going towards worthwhile charities. This year, Barrett-Jackson handled three noteworthy examples. The highest price among them was the first Ford Shelby GT350R Mustang with the VIN #001, which raised $1 million for the Juvenile Diabetes Research Foundation. General Motors donated the first new Chevy Corvette Z06 Convertible, the first retail example of the droptop supercar garnering $800,000 for the United Way. Along with the Z06, GM also donated the first new 2016 Cadillac CTS-V sedan, which brought in $170,000 for Detroit's College for Creative Studies. Although these were the headline Motown muscle machines furnished by the automakers themselves, they weren't the only vehicles auctioned off for worthy causes. A 1950 GM Futurliner bus donated by collector Ron Pratte led the charge when it brought in $4.65 million for the Armed Forces Foundation. Other lots included a custom Jeep Wrangler donated by SEMA ($85k), a new M5 donated by BMW ($800k), a '79 Oldsmobile Cutlass Hurst ($140k), '39 Cadillac LaSalle C-Hawk ($410k), Jeff Gordon's 1999 NASCAR-spec Chevy Monte Carlo ($500k) and a Victory Cross Country 8-Ball motorcycle ($180k). All told, the charity lots raised over $8.7 million for local and national charities.
