2013 Hyundai ix35 is a freshened-up Euro-Tucson

In places that aren't the United States, Hyundai calls its Tucson compact crossover the ix35. And as part of its Geneva Motor Show presence, the Korean automaker has debuted this freshened version of the C-segment CUV, showing some minor tweaks to an otherwise attractive package.
The most noticeable changes are found up front, where a revised grille slots in between newly designed headlamps that now feature LED running lights. Around back, the taillamps have also been given the nip/tuck treatment, and it appears some redesigned wheels have been included in this update, as well.
Hyundai has fitted its ix35 with a new, direct-injected version of its 2.0-liter naturally aspirated four-cylinder engine (with undisclosed power figures, natch). And when it comes time to put that power to the road, driver's will be able to use a new selectable electric power steering system similar to what's on the Elantra GT and Santa Fe Sport, with normal, comfort and sport modes.

Hyundai Sonata's slow sales start to trigger more daring redesign

On paper, the latest Hyundai Sonata has been a winner. The sedan sold 216,936 units in 2014, around 13,000 more than the previous year, and the new model posted healthy year-over-year gains in both December and November. However, according to a report from Wards Auto, the Korean brand isn't happy with how the vehicle is doing and is planning a redesign, to be timed with the future refresh. Unveiled at the 2014 New York Auto Show, the latest Sonata has a more refined, almost luxurious air about it, and the sedan ditches the swooping styling from the previous generation. It also comes at a slightly lower base price. But the more mature design is also the problem. Hyundai Motor America CEO Dave Zuchowski told Wards during the 2015 Detroit Auto Show that the new model was "not as distinctive" as its predecessor. Previously, "people would seek us out because we look different. And we don't get that now," he said. While no details on the redesign were divulged, Zuchowski said the company was already at work on the shape. He suggested the changes would debut for the Sonata's refresh, likely in the 2017 or 2018 model years. Autoblog reached out to Hyundai about the possible design change and spokesperson Derek Joyce told us, "Dave was simply referring to our normal mid-cycle refresh where it's typical to make styling tweaks." According to Wards, the latest Sonata isn't conquesting as many buyers from other brands as Hyundai would like. The company reportedly raised incentives to get them to move. So while sales were up, the automaker was disappointed. AutoTrader senior analyst Michelle Krebs confirmed to Autoblog that incentives were high for the Sonata, but that had nothing to do with its design. "The midsize car segment has fallen out of favor with buyers who want utilities so they are carrying very heavy incentives. We expect that trend to continue and then some in 2015," she said. A previous report also claimed that the 2015 Sonata wasn't living up to sales expectations in part due to its more traditional styling. But the company shot down those claims because the sedan was still rolling out the entire range to dealers at the time. Even now, Hyundai is still adding the Sonata Hybrid and Plug-In to the lineup in the coming year.

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.
