Hyundai spotted testing Prius-style hybrid

The Toyota Prius has become an automotive icon – maybe less so among actual automotive enthusiasts than with the public at large – to the extent that most anyone on the street would recognize its five-door hatchback form and immediately identify it as a hybrid. Little wonder that Honda tried to emulate it with the second-gen Insight, but while that didn't work out so well for Honda, it looks like Hyundai is preparing to go down the same road with a dedicated hybrid of its own. Our paparazzi on the ground in the Arctic Circle have spotted this protoytpe and tell us what we're looking at is a new Prius-fighter from the Korean automaker. Snapped up high on a transporter truck, you can see the orange high-voltage cables underneath and a label with the letters AE HEV – the latter standing, of course, for Hybrid Electric Vehicle. We wouldn't be surprised if the AE stood for Advanced Experimental or Alternative Energy or something of the sort. Tipped to be based on the same platform as the next-generation Elantra, the new Hyundai hybrid is said to pack a 1.6-liter inline-four working in parallel with an electric motor juiced by a lithium-ion battery pack. It's expected to begin production in the second half of 2016, with a plug-in and possibly other variants to follow a year to a year and a half after its initial launch.

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.

Hyundai, Kia recalling 1.2 million vehicles for seized engines

The Basics: Hyundai and Kia are recalling a total of 1,190,160 vehicles because the engine may seize, resulting in a crash. The vehicles affected are the 2013-2014 Sonata and Santa Fe Sport and the 2011-2014 Optima, 2012-2014 Sorento and 2011-2013 Sportage. The Problem: Errors during the machining process can cause a bearing in the engine to prematurely wear. This could cause the part to fail and the engine to seize. This in turn may cause a vehicle to crash. The issue was found due to the high number of warranty repairs for a recurring issue. Injuries/Deaths: There was no information on the websites for the National Highway Traffic Safety Administration, Hyundai, or Kia. We've reached out to the automakers for comment. The Fix: For Hyundai, the automaker will notify owners, and dealers will inspect the engine, replacing the engine short block, as necessary, free of charge. The recall is expected to begin May 19, 2017. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 162. The same goes for Kia, though the recall is expected to begin May 25, 2017. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC147. If You Own One: Wait for the notification letters from Hyundai and Kia. When possible, take your vehicle to your local dealer. If you want more details, contact either automaker at the number above.
