Minivan market not what it used to be, but margins make up for it

Residual values for last year's minivans are higher than they were in 2000.
Much like the station wagon was the shuttle of Baby Boomer generation, the minivan has been the primary means of transport for Generations X and Y. Just as the boomers abandoned the Country Squire, though, those kids that were toted around in Grand Caravans and Windstars are adults, and they certainly don't want to be seen in the cars their parents drove.

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.

2019 Kia K900 First Drive Review | The Stinger GT grows up

The Kia K900 has been an afterthought in the luxury market almost since it was launched about 4 years ago. Or maybe a never-thought. Through September of this year, Kia sold just 260 examples, which was about 90 fewer than the same time last year. And with sales like that, most of us figured Kia would just let the model quietly disappear into the ether, especially with the launch of the new Genesis luxury brand, and Kia's new halo, the Stinger. Considering the car's yacht-like demeanor and forgettable looks, we wouldn't have missed it. Yet Kia is determined to keep the K900 alive in America, and has introduced a completely redesigned model. Perhaps even more surprising than the fact that the model is back, is that it's actually quite good. Think of it as a bigger, more plush Kia Stinger. That may be hard to believe by just looking at it. While it's certainly better proportioned than its predecessor, with a body that highlights its rear-drive bones, it's boring. It hides its roots well, not getting the onlooker excited or leaving a major impression. There's hardly a sharp crease or bold character line to be seen – a stark contrast to the fierce, outre Stinger. It doesn't even look much like other Kias, which all share a family resemblance in their grilles and athletic stance. The K900 is a lot larger than the Stinger, too. The wheelbase is about 8 inches longer, and overall length is up by nearly a foot. Width and height are greater by roughly 2 and 3 inches respectively. This all puts the K900 in the size territory of full-size luxury flagships, but Kia says it's targeting buyers of midsize luxury sedans such as the Audi A6 and BMW 5 Series with a price of around $60,895 for the base model, and $64,895 for the VIP model. These are close estimates. It's a "more for your money" sort of argument, but there are more direct competitors to the K900 that muddy the water, like the Volvo S90, Lincoln Continental, and Cadillac CT6. On paper, all three seem to be compelling options to the K900 with lower base prices, similar size, and more distinctive styling. But the K900 has a major power advantage with its standard 365-horsepower twin-turbo V6. The S90's standard engine makes just 250 horsepower, and the optional non-hybrid engine just makes 316 horses. To beat the Kia, you have to get the hybrid S90 with 400 horsepower, and a base price of over $64,000.
