2015 Kia Soul EV whirrs in to the Windy City

Earlier this week, we got our first glimpse of the 2015 Kia Soul EV out on the road, completely uncovered. And even before then, executive editor Chris Paukert had the opportunity to drive a camouflaged electric Soul prototype on Kia's home turf in Korea. But now, finally, officially, the electron-happy Soul makes its debut at the Chicago Auto Show.
Powering the Soul EV is an 81-kilowatt electric motor that sends 109 horsepower and 210 pound-feet of torque to the front wheels. That's not immensely powerful, with Kia quoting a 0-60 time of "fewer than 12 seconds," but we're big fans of the instant torque thrust that EVs like the Soul provide. Top speed is electronically limited to approximately 90 miles per hour.
Kia says the Soul EV is good for roughly 80 to 100 miles of driving range.

Kia compact crossover caught completely uncovered, and it's called Seltos

Kia has been teasing a new, global small crossover with some sketches the past couple of weeks. Now we get to see the actual crossover — called the Kia Seltos — completely unveiled well before the actual reveal. It seems to be sized between the Kia Soul and the Kia Sportage. The photos also show that the drawings Kia released were clearly of the production car. Everything looks nearly identical. It also leans on many current design trends such as a black or contrasting-color roof separated by metallic trim, faux metallic skid plates on the bumpers, and a rising window line at the back. The car has more lines and creases than most of Kia's relatively organic designs of late. The headlights and taillights do have lots of nice detailing, though this is probably a high-level model, and those details may be lost on lower trims. We don't get a look at the interior, but if it's as faithful to the teaser images as the exterior, it should look fairly typical for a Kia. It will have a fairly low, horizontal dash with a large screen protruding from the middle. It looks as though a newer widescreen will be available, which we've seen in the Kia Telluride and K900. Considering the size of the Seltos, it would seem plausible for it to share the naturally aspirated 2.0-liter and turbocharged 1.6-liter engines from the Kia Soul and Forte. The naturally aspirated engine makes 147 horsepower and 132 pound-feet of torque, and the turbo engine makes 201 horsepower and 195 pound-feet of torque. As in those other Kias, the 2.0-liter engine would probably get a CVT while the 1.6-liter engine would likely get a dual-clutch transmission. All-wheel drive is also probably on the table, though we'll have to wait to see if it's offered on every trim and powertrain combination. Kia said the reveal will be this summer, so we may be waiting a couple more months for all those details.

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.
