Consumer Reports no longer recommends Honda Civic

Consumer Reports annual Car Reliability Survey is out, and yes, there are some big surprises. First and foremost? The venerable publication no longer recommends the Honda Civic. In fact, aside from the walking-dead CR-Z and limited-release Clarity fuel-cell car, the Civic is the only Honda to miss out on CR's prestigious nod. At the opposite end there's a surprise as well – Toyota and Lexus remain the most reliable brands on the market, but Buick cracked the top three. That's up from seventh last year, and the first time for an American brand to stand on the Consumer Reports podium. Mazda's entire lineup earned Recommended checks as well. Consumer Reports dinged the Civic for its "infuriating" touch-screen radio, lack of driver lumbar adjustability, the limited selection of cars on dealer lots fitted with Honda's popular Sensing system, and the company's decision to offer LaneWatch instead of a full-tilt blind-spot monitoring system. Its score? A lowly 58. The Civic isn't the only surprise drop from CR's Recommended ranks. The Audi A3, Ford F-150, Subaru WRX/STI, and Volkswagen Jetta, GTI, and Passat all lost the Consumer Reports' checkmark. On the flipside, a number of popular vehicles graduated to the Recommended ranks, including the BMW X5, Chevrolet Camaro, Corvette, and Cruze, Hyundai Santa Fe, Porsche Macan, and Tesla Model S. Perhaps the biggest surprise is the hilariously recall-prone Ford Escape getting a Recommended check – considering the popularity of Ford's small crossover, this is likely a coup for the brand, as it puts the Escape on a level playing field with the Recommended Toyota RAV4, Honda CR-V, and Nissan Rogue. While Ford is probably happy to see CR promote the Escape, the list wasn't as kind for every brand. For example, of the entire Fiat Chrysler Automobiles catalog, the ancient Chrysler 300 was the only car to score a check – there wasn't a single Dodge, Fiat, Jeep, Maserati, or Ram on the list. That hurts. FCA isn't alone at the low end, either. GMC, Jaguar Land Rover, Mini, and Mitsubishi don't have a vehicle on CR's list between them, while brands like Mercedes-Benz, Volvo, Nissan, Lincoln, Infiniti, and Cadillac only have a few models each.

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.

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.
