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 were our favorite cars of 2022

Favorite cars is different than best cars. The idea of "best" can speak to value and overall competitiveness in a given vehicle segment. There's lots of objectivity involved and to do a "best" list right, one really must be very thorough and as scientific as possible. This is not that list. This is about our favorites, so objectivity be damned. If we liked a Challenger Hellcat because it made loud noises or a Honda Odyssey because it made for a particularly special family vacation, fair game. These were the cars that most spoke to our collection of editors and the ones that stayed in our minds and hung in our hearts long after they left our driveway. — Senior Editor James Riswick 2022 GMC Hummer EV Senior Editor, Green, John Beltz Snyder: I didn't particularly expect to like the new Hummer. I wasn't a fan of the Hummer H2 or H3, so I wasn't automatically enthusiastic about this electric reboot. Fast EVs aren't hard to come by — and, in fact, may be too easy to come by — so its performance specs weren't enough to win me over. Despite videos to the contrary, pickups aren't my favorite vehicular format. And its excessive size and weight turned me off ... until I finally got behind the wheel.  This thing is wildly entertaining to drive. Watts to Freedom launch control is a neat party trick, sure, but the novelty wears off quickly. The novelty of Crab Walk, however, has staying power. The rear-wheel steering makes this behemoth feel much smaller than it is — the maneuverability is incredible, and useful. The air suspension provides tons of clearance, including a ridiculously high-riding Extract mode. I can't wait for lesser versions of the Hummer to make their way to market. Give me less power (for less money), but keep the off-road tricks onboard, and I'll be a happy camper. Senior Editor, Consumer, Jeremy Korzeniewski: If I could afford to put one of these in my driveway, I would. Sadly, I can't, so I won't (What's that, Janet? I got the lyric wrong?). Still, I love the dumb thing. Thankfully, I have another choice down below. 2022 Porsche 911 GT3 Associate Editor Byron Hurd: Yeah, duh, Porsches are good. But there's good, and then there's GT3. This is the feeling every performance-oriented RWD tuner is trying to replicate. This is hard, precise, surgical and immensely satisfying. To begin to explore this car on a public road is by itself an admission that you believe yourself to be above the rules as they apply to normal drivers.

Autoblog Minute: Ford Ranger, UK Mustang, Hyundai Hybrid

Ford may bring the Ranger back to the US, the UK goes nuts over the Mustang, and the battle of hybrids heats up with spy shots of the Toyota Prius and a new Hyundai. Autoblog's senior editor Greg Migliore reports on the weekly recap edition of Autoblog Minute. Show full video transcript text [00:00:00] Ford may bring the Ranger back to the US, the UK goes nuts over Mustang, and the battle of hybrids heats up with spy shots of Prius and a new Hyundai. I'm Autoblog senior editor Greg Migliore and this is your Autoblog Minute weekly recap. 2011 was the last time we saw Ford's midsize pickup in the US but according to a report from the Detroit News we could see production of the Ranger at the [00:00:30] Dearborn automaker's Michigan Assembly Plant as early as 2018. Ranger could compete with the Chevy Colorado and perhaps revive the compact and midsize pickup market for Ford, but the future of Ranger in the US depends a lot on Ford's ongoing negotiations with the UAW. About 2,000 orders for the 2015 Mustang were placed in the UK, tying up production of the pony car until July 2016. According to details in a press release from Ford UK, [00:01:00] it looks like Brits are a lot like their American cousins, opting for the 5.0 liter V8, with Race Red as the popular color of choice. Photos of the 2016 Toyota Prius leaked generating a lot of buzz over the styling. This fourth generation Prius will have some new competition as spy shots of a new Hyundai also surfaced this week. The car is said to be a hybrid and a bonafide "Prius fighter." Those are the highlights from the week that was. Be sure to check out my full recap this Saturday, [00:01:30] including the latest in FCA rumors for 2016. For Autoblog, I'm Greg Migliore.
