Hyundai shows off six custom creations in Vegas

Hyundai rolled in to SEMA this year with an array of six customized vehicles. And while it previewed several members of that lineup in the run up to the tuner expo, it has now brought them all together under one roof – namely that of the Las Vegas Convention Center. The fleet consists of three custom creations based on the Tucson crossover, two on the Genesis Coupe, and one on the Veloster. The Tucson lineup includes one by Bisimoto, another by John Pangilinan, and a third by Rockstar Performance Garage. In typical style, Bisimoto cranked the crossover up past 700 horsepower, thanks to a high-boost turbocharger running on flex fuel. Pangilinan crafted his JP Edition Tuscon for off-road adventure with a pop-up tent on the roof, brush guards, and a lifted suspension. And Rockstar went with a Baja-style off-road competition approach with a massive 6-inch lift kit and 32-inch tires. The Genesis Coupes include one by ARK Performance and another by TJIN. The former is dubbed the Solus edition, adopting a dual focus on performance and luxury with a wide body kit, carbon-fiber trim and a supercharged V6 stroked out to 4.0 liters to produce over 500 horsepower. The TJIN edition also ups the output past 500 horses with a supercharger from Bisimoto, plus a free-flowing exhaust, intercooler, and blow-off valve. KW coilover suspension, custom body kit, and green paint job finish it off. Finally, there's the Veloster Turbo R-Spec done up by Blood Type Racing with a black paint job, red racing stripe, carbon-fiber wide-body kit, and a 1.6-liter turbo four boosted up to – you guessed it – over 500 hp. Check out five of them together (sans the Bisimoto) in the slideshow above, or each of the six in the individual galleries at bottom for a closer look - along with the details in the press release below.

This year's builds feature three of Hyundai's all-new 2016 Tucson crossovers, two high-powered Genesis Coupes, and a Veloster Turbo R-Spec. Hyundai will be showcasing these creations at its SEMA display in Center Hall (booth #24387) at the Las Vegas Convention Center, Nov. 3-6, 2015.

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.

Is Hyundai's conservative new Sonata struggling out of the gate?

"But so far, Sonata sales are up compared with last year even while we're still ramping up to full speed," - Jim Trainor
According to Reuters, the redesigned-for-2015 Hyundai Sonata is not enjoying the same degree of success in the early going as the previous sixth-gen model, which proved to be one of the most important models in the company's history and ushered in the company's so-called "Fluidic Sculpture" design language that we still see today. Citing a recent review from The New York Times that called the car's more conservative styling "bland" and "boring," Reuters also points to analysts who claim the higher price of the new Sonata, as well as smaller rebates and incentives, are hurting sales. Honda and Toyota both offered anywhere from $600 to $800 more on the hoods of their Accord and Camry sedans last month.
