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.

Automakers score 8 out of top 20 most-watched ads on YouTube [w/videos]

Who would have ever thought there'd be a day where people are able to skip television commercials only to go to websites to watch them later? Such is the joy of a DVR and YouTube. AdWeek tabulated the 20 most-watched ads on YouTube, and found that nine were car-related including eight coming from automakers.
Volkswagen continued its Star Wars theme with two ads in the top 20, including the highest-ranking car commercial The Bark Side spot at number three with almost 18 million views, which doesn't even have a single car in it. Some of our favorites are from Chrysler with Clint Eastwood in It's Halftime in America and House Arrest with Charlie Sheen for the Fiat 500 Abarth. Chevrolet, Honda, Audi and Toyota were the other automakers in the top 20, but we'd be remiss if we didn't at least mention one of the coolest ads on the list, the Hot Wheels corkscrew jump.
Of all the car videos, only the Fiat ad wasn't played during a Super Bowl. Check out all eight videos - in order - after the jump. Nike took the top spot with its My Time is Now ad that has been seen online more than 20 million times with Pepsi's Uncle Drew posted up in the runner-up; some of the other videos include four Old Spice commercials and an ad in which Snoop Dogg is pedaling Hot Pockets.

Burt Reynolds' movie re-creations fetch $379,500 in Vegas

The recent death of Hollywood legend and automotive enthusiast Burt Reynolds helped drive up the value of four of his former cars from the 1970s and '80s, which sold last weekend at Barrett-Jackson's Las Vegas auction for a combined $379,500. Reynolds, who died Sept. 6 at age 82, had offered three Pontiac Trans Ams — two of them re-creations of the cars he drove in "Smokey and the Bandit" and "Hooper" and the third from 1984 used to promote his United States Football League team, the Tampa Bay Bandits. The fourth was a 1978 Chevrolet R30 pickup truck, styled like the one featured in "Cannonball Run." The "Bandit" re-creation, a 1978 Pontiac Firebird Trans Am that Reynolds ordered to be as "movie-correct" as possible but featuring a custom-built 200-4R automatic transmission, sold for $192,500. The car features a freshly built Pontiac 400 cubic-inch V8 mated to a four-speed automatic and featuring all-new Butler Performance parts and air-conditioning components. Reynolds reportedly said this was his favorite car from his films, and it even came with an authentic movie-correct CB radio and CB antenna. The red retro-rocket "Hooper" '78 Firebird, with a 403 cubic-inch V8 and a three-speed automatic, hammered for $88,000. By comparison, a gold 1978 Trans Am also offered at the Las Vegas auction but not connected to Reynolds fetched $27,500. The 1987 Chevy R30 pickup was a re-creation of the Indy Hauler pace truck seen jumping over a moving freight train in "Cannonball Run." It hammered for $49,500. The fourth car never appeared in any of Reynolds' films but is instead the only surviving example of two Trans Ams used to promote the Tampa Bay Bandits of the now-defunct USFL, having been driven out onto the field by Reynolds and his late friend and co-star, Jerry Reed, during opening day one season. It also sold for $49,500. At the Barrett-Jackson Scottsdale Auction in 2016, Reynolds accompanied a 1977 Trans Am used to promote "Bandit" onto the auction block. That car sold for $550,000.
