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.

2020 Ford Escape hybrids vs other crossover fuel sippers: How they compare on paper

Along with a new generation of Escape, Ford also reintroduced the world to the 2020 Ford Escape Hybrid. And if that weren't enough, Ford is adding a plug-in hybrid version. This is a sign of the times: people are more crossover crazy than ever, but are also seeking ways to use less fuel, whether it's for environmental or purely money-motivated reasons. The Ford hybrids aren't the only fuel-efficient compact crossovers on the market. They will be going head-to-head with conventional hybrids including the 2019 Kia Niro, 2019 Nissan Rogue Hybrid and 2019 Toyota RAV4 Hybrid. There are other plug-in hybrids including the 2019 Subaru Crosstrek PHEV, 2019 Mitsubishi Outlander PHEV and the plug-in version of the 2019 Kia Niro. There are even a couple diesels in the form of the 2019 Chevy Equinox and 2019 GMC Terrain. So we've rounded up the details on all these crossovers to see who leads and lags in criteria such as power, fuel efficiency, space and price. Check out all their details below. 2019 Subaru Crosstrek Hybrid View 68 Photos How do their engines and fuel economy compare? Conventional Hybrids and Diesels Let's face it, if you're buying one of these crossovers, one of the things that matters most to you is just how frugal with fuel they are. We'll start off with the conventional hybrids and diesels, and the clear victor is the Kia Niro, which in base FE trim, manages to hit 50 mpg combined. This is thanks to it sharing its powertrain with the Hyundai Ioniq, the Hyundai equivalent of the Toyota Prius. Buyers should take note that only the FE returns such high fuel economy. The LX and EX drop to 49 mpg, and the S Touring and Touring get 43. Even then, the least efficient Niro is the most efficient of the normal hybrids and diesels. It is nearly the least powerful, though, with 139 horsepower. Just behind it is the Toyota RAV4 Hybrid. It delivers 40 mpg combined, and it has an ace up its sleeve: it comes standard with all-wheel drive. Every other vehicle in this powertrain group has front drive standard, and the Niro isn't available with all-wheel drive at all. If that weren't enough, the RAV4 Hybrid also boasts the most power at 219 horses. While we can't say anything about Escape Hybrid fuel economy, we do know that it will make 198 horsepower, which is close to the class-leading RAV4. The least powerful of these is the Equinox and Terrain, and they return the worst fuel economy at 32 mpg.

GM struggles to sell small cars, plans to lay off 2,084 employees at two plants

Due to low demand for some of its vehicles, General Motors plans to cut 2,084 jobs at its assembly plants in Lordstown, OH and Lansing, MI. At the same time, the automaker also announced plans to invest approximately $900 million in three of its facilities – the Toledo Transmission Operations in Ohio, Bedford Casting Operations in Indiana, and Lansing Grand River in Michigan - for future products. GM will discontinue the third shift at both the Lansing Grand River plant and the Lordstown, OH plant. The Cadillac ATS, Cadillac CTS, and Chevrolet Camaro are made at the automaker's plant in Michigan, which currently has 2,700 employees. The move to eliminate the third shift affects 810 hourly workers, as well as 29 salaried employees, starting on January 16th. The plant in Lordstown, OH currently has 4,500 employees and makes the Chevrolet Cruze sedan. The plan to discontinue the third shift will affect 43 salaried workers and 1,202 hourly employees and will start on January 23rd. As Fortune points out, sales of the Cruze are down 20 percent through October, while sales of the Cadillac ATS and CTS were down 17 percent through the same period of time. In addition to cutting the third shift at both assembly plants, the automaker plans to invest a total of $900 million between three of its facilities for unnamed future products. GM's Toledo Transmission Operations will receive $667.6 million, the Lansing Grand River Assembly plant will receive $211 million, and the automaker's Bedford Casting Operations will get $37 million. Last year, GM cut roughly 500 jobs from its Orion Township factory due to slow sales of the Chevrolet Sonic and Buick Verano, with surging crossover and SUV sales as the most likely culprit. With GM posting much healthier sales figures for the Chevrolet Equinox and Cadillac XT5 compared to the ATS, CTS, and Cruze, it looks like compact SUVs are to blame for this year's layoffs as well.
