10 automakers sued over keyless ignitions

Keyless ignition has rapidly proliferated throughout the auto industry to become a fairly normal feature on new cars. It's supposed to offer the convenience of keeping the fob in your pocket and just pressing a button to drive away. However, ten major automakers are now being sued in US District Court over claims that the system is dangerous, Reuters reports. The suit alleges that people are forgetting to shut off the engine, and the lack of an idle timer is the cause for 13 deaths by carbon monoxide poisoning and multiple injuries. The suit currently includes 28 plaintiffs, according to Reuters, but the lawyers are asking for class-action status to potentially add many more. The case goes after a major swath of the industry, including BMW, Daimler, FCA, Ford, General Motors, Honda, Hyundai, Nissan, Toyota, and Volkswagen, plus their related brands like Acura, Infiniti, Mini, and Lexus. In all, over five million vehicles are affected. The assertion here is that people walk away from their vehicle without shutting it off because they believe the engine shuts off automatically. If parked in a garage, carbon monoxide can build up, leading to poisoning. The lawyers claim automakers know this is a problem and also cite 27 complaints to the National Highway Traffic Safety Administration about the issue, according to Reuters. The plaintiffs are asking for an automatic shut-off and damages from the companies. These concerns have come up before, though. Toyota previously faced a lawsuit over a carbon monoxide death after a woman accidentally left her Lexus running. Also earlier this year, GM recalled 64,186 examples of the 2011-2013 Chevrolet Volt because owners weren't shutting them off. The problem resulted in two injuries, and the company released a software update to limit the idling time.

Hyundai Veloster N reveals menacing grille, big wing

Once again, the Hyundai Veloster N has been spotted at the 'Ring. This time, though, the car was sporting considerably less camouflage, giving us our best look yet at the first N car for the United States. The first thing most people will notice is that the top-spec Veloster will feature a massive black grille, just as the outgoing Veloster Turbo had. It does differ from the old one in that the far corners have been brought up higher and squared off to bring it inline with the new "cascade" corporate grille. The greenhouse is more visible now, too. And like the grille, it has been squared off a bit at the rear corners. It appears there's more glass, either due to the roof being raised slightly, or the window sills being dropped. The back of the Veloster N may reveal the most, though. This car gives us our first uninhibited glimpse at the rear wing, and it's a big 'un that closely hugs the bodywork on each end. The triangular shape in the middle suggests it will have a brake light similar to the i30 N. We can also finally see the taillights better. They're more horizontal than the previous car's, and they're also mounted flush to the window seam. Looking closely, we can see that they extend forward, still hugging the rear window, and the edge leads into a arching line created by the side windows. The rear glass is interesting, too, because there's just a single rear pane, rather than the old model's split glass similar to the Honda CR-X, Toyota Prius, and Hyundai Ioniq. The rear bumper also features an aggressive diffuser design in the bottom, and, as with the i30 N, there is a red accent line. We'll probably see another red line at the front. The exhaust has two outlets on each end as well, which is further indication that this is the N model and not a standard Veloster or Veloster Turbo. Since we won't be getting the i30 N in the U.S., we wouldn't be surprised if the Veloster N carried the same turbocharged four-cylinder as that car, which produces 271 horsepower and 260 pound-feet of torque. After all, if the i30 N isn't sold here, there's no reason not to hamstring the Veloster to keep it from cannibalizing sales. Continuing on that line of thinking, it will likely use the same front-wheel-drive system with limited-slip differential and six-speed manual transmission. We also expect to see a full reveal of the Veloster line later this year.

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.
