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.

Autoblog's guilty pleasure cars

Guilty pleasures are part of life – don't even try to pretend like you don't have one (or two, or six). In the non-automotive space, this could come down to that secret playlist in your iPhone of songs you'll only listen to when you're alone; or think of that one TV show you really do love, but won't admit to your friends. I've got plenty, and so do you. Going back to cars, here's a particularly juicy one for me: several years ago, I had a mad crush on the very last iteration of the Cadillac DTS. Oh yes, the front-wheel-drive, Northstar V8-powered sofa-on-wheels that was the last remaining shred of the elderly-swooning days of Cadillac's past. Every time I had the chance to drive one, I was secretly giddy. Don't hate me, okay? These days, the DTS is gone, but I've still got a mess of other cars that hold a special place in my heart. And in the spirit of camaraderie, I've asked my other Autoblog editors to tell me some of their guilty pleasure cars, as well – Seyth Miersma, as you can see above, has a few choice emotions to share about the Mitsubishi Lancer Evolution. Read on to find out what cars make us secretly happy. Mercedes-Benz SL65 AMG This decadent convertible is the epitome of the guilty pleasure. It's big, powerful, fairly heavy and it's richly appointed inside and out. It's a chocolate eclair with the three-pointed star on the hood. Given my druthers, I'd take the SL65 AMG, which delivers 621 horsepower and 738 pound-feet of torque. That output is borderline absurd for this laid-back convertible. I don't care. You don't need dessert. Sometimes you just crave it. The SL line is about the feel you get on the road. The roof is open. The air, sun and engine sounds all embrace you. It's the same dynamic you could have experienced in a Mercedes a century ago, yet the SL gives you the most modern of luxuries. An Airscarf feature that warms my neck and shoulders through a vent embedded in the seat? Yes, please. Sure, it's an old-guy car. Mr. Burns and Lord Grantham are probably too young and hip for an SL65. I don't care. This is my guilty pleasure. Release the hounds. – Greg Migliore Senior Editor Ford Flex I drove my first Flex in 2009 when my mother let me borrow hers for the summer while I was away at college. The incredibly spacious interior made moving twice that summer a breeze, and the 200-mile trips up north were quite comfortable.

15 vehicles most likely to surpass 200,000 miles

Americans drive a lot. Collectively, we put, on average, more than 13,000 miles on our cars each year according to the U.S. Department of Transportation. Because of this, a vehicle's ability to travel long distances without major problems is a huge consideration when it comes time to purchase a new one. It's also worth remembering that keeping an older car on the road instead of trashing it and buying new can be considered an eco-friendly decision. After all, it takes a lot of resources to build a car. iSeeCars.com, a website that aggregates used car listings from all around the country, recently ran through the numbers on millions of vehicles that are currently on the road to determine which last the longest. Alternatively, you could choose to look at this list as vehicles likely to be driven by owners who travel long distances. Either way, we've laid out the top 15 vehicles most likely to hit or even surpass the 200,000-mile mark. It's important to note that while these are the vehicles that have stood the test of time up until today, we can't guarantee future results if you decide to opt for one of these from a current model year. That said, unless we specifically say so in the text below, we've used pictures of current models for illustrative purposes. Now, with all of that out of the way, scroll on down for the top 15 vehicles most likely to crest 200,000 miles. 15: Toyota Sienna 14: Honda Odyssey The 15th spot and 14th spot on the list of the top 15 vehicles most likely to surpass 200,000 miles are both minivans. Spoiler alert: They will be the only two minivans on the list. According to iSeeCars, 3.2% of both of these family haulers crest the 200,000-mile mark, making them the best bets for families looking to put a ton of miles on their machines. 13: Honda Ridgeline 12: GMC Yukon The next spot on the list is occupied by the Honda Ridgeline pickup truck with 3.7% lasting past 200,000 miles. Unlike any of the other midsize trucks it competes with, the Ridgeline is based on a unibody chassis. Opting for this more car-like structure — as opposed to a traditional body-on-frame layout — allows Honda's hauler to ride and drive more like a car. Up next is the GMC Yukon, also with 3.7% past the 200K mark, and the first, but very much not the last, big traditional SUV you'll see on the list. In fact, get ready to see a whole bunch of 'em, including several from GMC parent General Motors.
