Why BMWs are cheaper than Hyundais in Korea

Bloomberg reports shifting tariff regulations have upended the traditional automotive pecking order in Korea. Thanks to cheaper import taxes, foreign brands have seen market share jump from 28 percent to 41 percent over the last two years. BMW, Mercedes-Benz and Audi have all capitalized on the shift, with domestics like Hyundai and Kia suffering at the hands of their German rivals.
Taxes on European imports have fallen from 8 percent in 2011 to just 3.2 percent today. Over the next few years, tariffs will all but be eliminated for most imports, and taxes on US-made vehicles are expected to fall to just 4 percent in 2014. By 2016, that number will be zero. Needless to say, Hyundai and Kia are concerned about the shift.
Hyundai has seen profit fall by 15 percent last quarter, and the company says it is on pace to see the slowest sales growth since 2007. The company's shares have fallen by 12 percent. In order to stem the losses, Hyundai has discounted its midsize sedans and started working on diesel engine options.

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.

The anti-Prius | 2017 Kia Niro Hybrid First Drive

The 2017 Kia Niro is a significant model for the brand. It's the company's first car designed from the get-go to be a hybrid. And as Kia's VP of product planning explains, it's helping lead the company's push to improve fuel economy by 25 percent across the board. So it's kind of funny that almost everything about this car reads as "conventional" or simply "normal." There are exceptions to this. Under the attractive – if not adventurous – skin is some interesting technology. Most of the mechanicals are shared with the upcoming Hyundai Ioniq, including the direct-injected 1.6-liter inline-four and electric motor that send power to the front wheels. The powertrain makes a combined 139 horsepower and 195 pound-feet of torque. Kia also implemented various aerodynamic and weight aids to make the most of the engine and motor. The Niro features air curtains, a rear spoiler, and active air shutters to help achieve a 0.29 coefficient of drag, and the hood, hatch, brake calipers, and some suspension components are all made of aluminum. Plus, when ordered with navigation, the Niro will provide tips on driving more efficiently, and will use topographical information to use electric power in the most efficient manner. The various bits of fuel-maximizing technology mean the Niro manages Prius-like fuel economy ratings of 52 mpg in the city, 49 on the highway, and 50 combined. That's only for the base FE model, though. Moving up to the slightly better-equipped LX and EX models yields a small decrease to 51 city, 46 highway, and 49 overall. If you opt for the Touring model, shown here, because you want all the bells and whistles, be ready to sacrifice more mileage – it only manages 46 city, 40 highway, and 43 overall. Kia says this is due to the increased weight of the standard features, different roof rails that change the aerodynamic profile, and the larger, wider 18-inch wheels and tires that increase the rotational mass and rolling resistance. All of the effort Kia put into making the Niro a highly efficient Prius fighter seems to have been matched by an effort to make the car appear as normal as possible and give it the broadest appeal. So, no polarizing looks like on the latest Prius and Prius Prime. Glancing at it, you'd say the Niro is just another crossover. The greenhouse looks like a scaled-down version of the Sorento's. That's not necessarily a bad thing, since the larger Kia crossover is fairly handsome.
