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.

Korea's sport compact | 2017 Hyundai Elantra Sport First Drive

When we drove the then all-new 2017 Hyundai Elantra earlier this year, we came away impressed but slightly bored. There is nothing fundamentally flawed with the compact sedan, but there also is nothing about the car that gets our blood pumping. The new Elantra is an affordable and reasonably well-equipped people mover. It's an improvement over its predecessor, but the driving experience leaves us indifferent. Hyundai was aware of this from the outset. The product plan includes the Sport model you see here, intended to inject some life into what is otherwise a rather milquetoast car. On paper, everything looks good and all of the right boxes are checked, including more power and a tighter suspension. Hyundai was clear that this is far more than just an appearance package like the previous generation's Sport trim. As such, the new Elantra Sport is fitted with a 201-horsepower, 1.6-liter turbocharged engine mated to either a six-speed manual or a seven-speed dual clutch automatic. A revised suspension replaces the standard torsion-beam rear axle with a fully independent multi-link rear setup, paired with bigger brakes, wheels, and tires. Other accoutrements, like sport seats and a flat-bottomed steering wheel, are also included. Check, check, check. The Elantra Sport with a manual transmission starts at $21,650 before destination and, sitting just below the top-of-the-range Limited model, comes very well equipped for the price. Heated leather seats are standard, as are HID headlights, keyless entry and ignition, and a seven-inch touchscreen display with Apple CarPlay and Android Auto. That's a lot of equipment for a car in this size and price range. The only option on both the manual and paddle-shifted DCT model (that one starts at $22,750) is the $2,400 Premium Package. It adds an extra inch to the display, navigation, an eight-speaker Infinity sound system, Hyundai's Blue Link connectivity, a sunroof, blind-spot monitoring, rear cross-traffic alert, dual automatic climate control with an auto defogger, and an auto-dimming rearview mirror with HomeLink and a compass. Lots of checks in lots of boxes at a reasonable price point and a long warranty has been Hyundai's modus operandi for a while now, and that's fine for most of its models. It's the case with the non-Sport Elantra, which is packed with features but otherwise makes us shrug. The Sport may not be a revolution, but it is a lot of fun to drive.

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.
