Next Hyundai Elantra GT hatchback previewed by i30 teaser

The Elantra GT hatchback looked a bit neglected after its sedan sibling was introduced last year. That said, the Elantra hatchbacks have historically been released after the sedan, and usually had significant differences between the two body styles. Based on this latest teaser from Hyundai, the hatchback will continue its unique streak. The teaser is officially for the European i30, but the i30 and Elantra hatchbacks have been the same vehicles since the late 2000s. There's also no sign of the American version being dropped or deviating from its European twin, so it seems a safe bet that this newest i30 will come here with the Elantra name. Hyundai does make it clear that this car was made with Europe in mind though, since both the press release and video tout the fact that all of the styling and development work was done in Europe. Peter Schreyer, lead designer for the Hyundai group, says this car is "the next step to how Hyundai design should be." So look for key design elements like the "cascading grille" to appear in future Hyundai vehicles. Speaking of design elements, we can actually spot a decent amount of them in the teaser image and video. The grille extends down the front of the bumper in a similar fashion to the sedan. Overall, the shape of the car looks more formal and upright than the steeply raked design of the current model. In addition, the sheet metal appears to be much less busy, with far fewer swoops and lines. The car will be fully revealed on September 7 just before the Paris Motor Show. Related Video:

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.

2016 Hyundai Elantra spied uncovered

The next-generation Hyundai Elantra has been speculated on and teased throughout this year. In March we got a leaked photo of a South Korean-market Elantra, the question being if this is was actually the new car and if we'd get in the US. Then we got officially sanctioned sketches of the exterior and the interior. Now Korean site Auto Tribune has leaked photos of the next Korean-market Avante, which is our Elantra, and they actually line up with the automaker sketches. According to Google Translate, the pictures were taken at a Hyundai factory in South Korea by a contractor. If this is the real deal, Fluidic Sculpture has given way to a grille that might want to at least send a "Thank You" note to Audi. Flanking that are smoother lines and a more subtle treatment of the front end, with sleek, pulled-back headlights decorated with a lengthy LED signature above boomerang inlets in the bumper. The sides have been flattened out, losing some of dimensionality of the current car to go more mature. The rear end looks similar to the current sedan, but wider, with long taillights featuring three LED elements. Inside, a three-spoke steering wheel veers toward the plain, and the current continuous waterfall center console gives way to a two-section instrument panel that has an eight-inch infotainment screen at the top, above HVAC controls. At the base there's an open cubby that doesn't look to have a cover, and the gear selector lever incline appears reduced. The overall impression is less engaging to the eye than now. Auto Tribune says a 1.6 liter GDI is under hood, which puts out 175 horsepower and 196 pound-feet of torque in the 2016 Tucson. We'll see the real car at the LA Auto Show later this year.
