Hyundai recalls 24k Genesis sedans over electrical issue

An electrical problem has prompted Hyundai and the National Highway Traffic Safety Administration to issue a recall for the 2015 Genesis. The problem arises when water leaks into the taillight assembly, which – in a way that would only make sense to an electrician – could cause the incorrect gear to be displayed on the instrument panel or even a delay in switching from Park to Reverse or Drive. Needless to say, if the driver doesn't know into which position the transmission has shifted, that could increase the likelihood of a crash. The issue affects an estimated 24,400 units of the 2015 Genesis in the United States – specifically those manufactured between February 21, 2014, and January 24, 2015. Owners of those vehicles can expect to hear from their local dealer to arrange the installation of additional waterproofing pads to prevent the troublesome moisture from leaking in to the taillights. RECALL Subject : Water may Leak into Rear Combination Lamp Assembly Report Receipt Date: FEB 19, 2015 NHTSA Campaign Number: 15V097000 Component(s): ELECTRICAL SYSTEM , EXTERIOR LIGHTING , POWER TRAIN Potential Number of Units Affected: 24,400 Manufacturer: Hyundai Motor America SUMMARY: Hyundai Motor America (Hyundai) is recalling certain model year 2015 Genesis vehicles manufactured February 21, 2014, to January 24, 2015. Water may leak into the rear combination lamp assemblies and cause an incorrect gear display on the instrument panel or a delay in the engagement of the selected gear when the vehicle is shifted from Park to Reverse or Drive. CONSEQUENCE: If the incorrect gear is being displayed, the vehicle may move in an unintended direction, increasing the risk of a crash. REMEDY: Hyundai will notify owners, and dealers will apply pads to prevent water intrusion into the combination lamp housing, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 128. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Does this Hyundai Intrado concept preview the next Tucson?

The second generation of Hyundai's Fluidic Sculpture design language has arrived a bit early, thanks to these leaked images of the Korean automaker's Intrado Concept. Set to make its big debut at next month's Geneva Motor Show, the three-door crossover is based on a next-generation version of the hydrogen powertrain used in Europe's ix35 Fuel Cell (that'd be a hydrogen Tucson, for anyone who's wondering).
We can see some 2015 Genesis Sedan in the grille, but the sharp, narrow LED headlights are something different. The c-shaped LED taillights also look good, although we're less sure about the odd fairings around the wheel wells. Overall, it's not a terrible design in our minds, but it probably won't be the pretties vehicle to debut in Geneva.
But instead of focusing on the design, let's talk about what impact the Intrado may have on Hyundai. Aside from the hydrogen powertrain, it seems as if the Intrado's design is too conservative to be a pure concept. Instead, and as you may have guessed from our headline, we're thinking this could be a preview of the next-generation Tucson. Considering the Tucson and its cousin the ix35 are the oldest vehicles in Hyundai's lineup (not counting the Sonata, which is getting replaced at the New York show) and it's a vehicle sold worldwide, previewing its replacement on a stage as big as Geneva doesn't strike us as a bad idea.

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.
