Hyundai recalls 10k Genesis Coupes for detached driveshafts

Hyundai has issued a recall for 10,800 examples of the Genesis Coupe. The problem with vehicles affected rests with the differential, which may have been misaligned with the crossmember of the rear suspension. In such a case, the bolts securing the differential may loosen, and could lead to the driveshaft disconnecting entirely, resulting in the complete loss of propulsion. The recall specifically affects certain models manufactured between December 28, 2011, and April 6, 2015. The problem is only with those units fitted with the six-speed manual transmission and not the eight-speed automatic. To address the problem, owners will be asked to bring their Genesis Coupes in to their local dealer to "verify the proper assembly of the differential." The Genesis Coupe was first introduced in its home market back in 2008, and arrived in North America the following year as a 2010 model. The most recent revision happened in 2013 – the model year with which this recall begins. A completely new model is expected to arrive soon as part of the new Genesis luxury sub-brand's lineup.

In the affected vehicles, if the differential and the suspension rear crossmember were not properly aligned during vehicle assembly, the bolts that secure the differential may loosen. CONSEQUENCE: If the rear differential loosens from its mounting position, the driveshaft may disconnect from the differential, resulting in a loss of propulsion and an increased risk of a crash. REMEDY: Hyundai will notify owners, and dealers will verify the proper assembly of the differential, free of charge. The recall is expected to begin on January 11, 2016. Owners may contact Hyundai's customer service at 1-855-671-3059. Hyundai's number for this recall is 135. 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.

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.

2017 Hyundai Ioniq takes three-pronged approach to electrification

The Geneva Motor Show may be dominated by super/hypercars, but there is some more sensible metal on display. And one of the most reasonable cars might be the trifecta of Hyundai Ioniq models. This three-prong approach to electrification is a very aggressive move for Hyundai. A hybrid wouldn't be a big deal. Nor would a plug-in-electric model. But launching both of those vehicles alongside a pure EV is a very bold decision. In fact, if the full Ioniq range were to launch in the United States – which still isn't a certainty – Hyundai would be one of the only brands to offer all three branches of electrification in the same showroom. The hybrid model outguns the 121-system-horsepower Toyota Prius. Thanks to its 1.6-liter Kappa four-cylinder, 43-hp electric motor, and 1.56-kWh battery pack, there's a total of 139 hp and up to 195 pound-feet of torque. The plug-in model makes some changes to that formula, significantly increasing the size of the battery pack to a larger 8.9 kWh and increasing the power of the electric motor to an even 60 hp. Hyundai hasn't said if system output has been changed, but we do know the PHV will cover 31 miles on pure electricity. View 14 Photos As we covered in our original post, the EV Ioniq is something of an unknown quantity. Hyundai's lips loosened slightly in Geneva, though, revealing that the electric motor will produce up to 218 lb-ft of torque. That's in addition to 118 horsepower and an estimated range of 155 miles. And not that EV drivers are known speed demons, but Hyundai claims its newest EV will hit 103 miles per hour. This estimated range and torque output best America's two most notable EVs, the Ford Focus Electric and Nissan Leaf, although it's fair to point out that this duo is relatively long in the tooth. While it seems plausible that Hyundai will at least offer part of the Ioniq range in America, at this point it's just too early to be certain of anything.
