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 plans Level 4 autonomy by 2021 in a fuel-cell car

SAN FRANCISCO — Silicon Valley startup Aurora announced on Thursday partnerships with Volkswagen AG and Hyundai to develop a self-driving system within their vehicles, the latest tie-up between global automakers and Silicon Valley tech companies. Aurora was founded in 2016 by robotics expert Drew Bagnell, Chris Urmson, who came from Alphabet Inc's Google, and Sterling Anderson, who formerly worked at Tesla. For Hyundai, Aurora's technology will be incorporated into custom-developed models and tested in markets including China. Hyundai said the first model to be used in testing will be its latest generation fuel-cell vehicle, debuting at the CES technology conference in Las Vegas next week. The model name of the car, shown above, will be announced then. Under the alliance, Hyundai plans to commercialize level 4 autonomous vehicles — which can operate without human input or even human oversight under select conditions — in unidentified "pilot smart cities" by 2021. This is the first announcement on a self-driving technology partnership by the South Korean carmaker, which has traditionally shunned tie-ups in favor of developing technology in-house. The strategy has raised investor concerns that it may be left behind in the race for self-driving and electric cars. A company spokeswoman said Hyundai has "various collaborations" under way in self-driving technology and would continue to pursue cooperation. In a statement, Volkswagen said Aurora's self-driving technology can be integrated over time across the automaker's brands and in different product categories, whether self-driving pods, shuttles, delivery vans or self-driving trucks. Aurora and Volkswagen said they had been working together over the past six months to integrate Aurora's sensors, hardware and software into the German carmakers' electric vehicles to develop self-driving ride services in cities. The non-exclusive partnerships mark the first deals for the young Silicon Valley company and show how some carmakers have chosen to partner with technology companies with more experience in artificial intelligence, deep learning and robotics in order to save time and money bringing self-driving cars to market. Within the self-driving car space, Waymo — formerly Google's autonomous program headed by Urmson — is offering something similar. The tech company has been working with Fiat Chrysler since 2016 to outfit its Chrysler Pacifica minivans with autonomous technology.
