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.

Hyundai CVVD engine brings another dimension to valve timing

A new technology from Hyundai Motor Group places another marker on the march to more efficient internal combustion engines. Called Continuously Variable Valve Duration, the innovation permits two options for how long the intake valves remain open during the combustion cycle. The feature adds a third take on valve chicanery, atop variable valve timing that changes when valves open, and variable valve lift that changes how far valves open. Hyundai says the feature returns a 4% improvement in performance, a 5% increase in fuel economy, and lowers emissions by 12%. Hyundai applied for two patents on the valvetrain process in South Korea in 2011 and again in 2015. The altered valve duration in this latest iteration is made possible by two movable arms inside the camshaft. Each arm is anchored at its base to a pin at the center of the camshaft, while the end of each arm extends toward the edge of the camshaft. Changing the position of the pin in the center of the camshaft changes the angle of the arms relative to one another, which moves the camshaft along its mounting rod. Voila, a new intake cam profile that either lengthens or shortens valve overlap.   During low-speed spells at low load, CVVD opens the intake valve from the middle to the end of compression stroke. The weaker detonation isn't a factor at low load, and the reduced friction during compression improves fuel economy. During heavy engine loads, the intake valve closes at the beginning of the compression stroke to maximize the amount of air mixed for detonation, boosting torque. Four additional features enhance the benefits of CVVD. A more powerful direct injection system increases fuel spray pressure from 250 bar to 350 bar. Hyundai doesn't go into details on its Integrated Thermal Management System, but says the ITMS "quickly heats or cools the engine to the optimal temperature." Low-friction components lower overall engine friction by 34 percent. And a low-pressure exhaust gas recirculation layout diverts low-pressure exhaust gas from the traditional EGR route to the turbocharger compressor under high load for better fuel efficiency.   The first engine to boast the new tech is the Smartstream G1.6 T-GDi four-cylinder, which produces 180 horsepower and 195 pound-feet of torque. It will appear in the 2020 Hyundai Sonata Turbo going on sale in South Korea later this year.

Are old airbags killers?

Takata airbags may not be the only ones with some very serious problems. A new report from TheDetroitBureau.com claims that the National Highway Traffic Safety Administration has opened its second investigation into bad airbag inflators, and this time, they aren't from Takata. The focus of this latest case is on the airbag inflators in some 500,000 older Chrysler Town and Country minivans and Kia Optima sedans, all of which come from ARC Automotive. While the Takata case looks at problems stemming from the engineering and production process, the ARC investigation focuses on the age of the inflators. As TDB explains, airbag inflators are essentially what the military refers to as shaped charges, sort of like Claymores (for fans of the Call of Duty series). In combat, they blow up in a specific direction, protecting those behind the explosion, although in the case of airbags, the explosion "[creates] a precise rush of hot gases" that inflate the bags. NHTSA's worry is that with the increased average age of today's vehicles, years and years of being bounced, jolted, and shaken about and exposed to often-radical temperature changes have altered the nature of the explosives in these vehicles, causing too big of an explosion. "It may be a reasonable assumption that as these things age they deteriorate." – Analyst George Peterson "It may be a reasonable assumption that as these things age they deteriorate," analyst George Peterson told TheDetroitBureau.com. NHTSA boss Mark Rosekind backed up aging angle. "Cars are lasting on the road a lot longer than ever before," Rosekind told TDB, adding that seals could start breaking down. "Is aging now an issue? That's part of the investigation going on." NHTSA has only identified two "incidents" so far, although according to Center for Auto Safety Director Clarence Ditlow, there's genuine concern that there could be additional unidentified cases. "Could we have missed more? That could be the case," Ditlow told TDB, citing the misidentified deaths in the Takata investigation. Ditlow was quick to point out that, even in older vehicles, airbags are much more likely to protect than harm. "No one is saying you should disable your airbags," the safety advocate told TDB. "You're far more likely to be helped than hurt by one if they go off." At least one automaker, meanwhile, has already been advised of the investigation by NHTSA and is checking its airbags.
