Hyundai and Rhys Millen reunite, will return to Pikes Peak with new RWD racer, Genesis Coupe

Last September, Hyundai confirmed that it was exiting all of its motorsports programs in North America. That left Rhys Millen Racing without a title sponsor for its Formula Drift and Global RallyCross Championship series challengers. It also looked to have meant the end of a partnership that last year resulted in a record-setting run at Pikes Peak when Rhys Millen established the new benchmark for a run up the Colorado mountain in a production-based race car.
Hyundai clarified that September report by saying it was "reconsidering our continued involvement in Pikes Peak International Hill Climb, having achieved the world record in a Hyundai Genesis Coupe this year." The return is official, with Hyundai saying it is going back to the peak with Millen and two cars, one of them a "purpose-built unlimited class rear-drive," the other being the Hyundai Genesis Coupe-based racer that set last year's record in the time attack two-wheel-drive class.
Hyundai wants to show off the strength of its engineering, so the unlimited car will have something like 900 horsepower and 800 pound-feet of torque while using the production block, cylinder heads, bearings and accessories of its Lambda V6 engine. You can read more about the effort in the press release below, and click the image above for an enlarged view of what's coming.

2015 Hyundai Sonata

Completely redesigning a vehicle competing in a fiercely contested segment requires delicately balancing styling, performance, safety, efficiency, innovation, passenger comfort and pricing, while simultaneously not alienating model loyalists. In other words, it's no simple task.
Automakers generally follow one of two paths. Some take a conservative approach and choose to raise each bar marginally, in an effort to appease all and estrange none. Others strategically take risks and focus on specific attributes in an attempt to shift perception about their vehicle.
With its all-new 2015 Sonata, Hyundai has taken the second approach when overhauling one of its best-selling vehicles. The Korean automaker has executed an impressive number of targeted improvements, yet it's also softened some of its predecessor's qualities in an attempt to demonstrate greater refinement and position its midsize sedan upscale. Whereas the outgoing car successfully aimed to establish itself as a credible contender in the midsize segment, the new model is gunning for customers that might otherwise be seeking entry-level models from luxury automakers.

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.
