Kia Optima Sportwagon spied before Geneva

Kia showed off the Sportspace concept at the Geneva Motor Show this year, and we knew at the time that it previewed design elements that would migrate to the Optima sedan. On top of that, it's keeping its hump to transition into the Optima Sportwagon for what we presume will be audiences outside the US. When we asked Kia about the chance of it coming here, a company spokesman responded: "Right now we don't have plans to bring the Optima Sportwagon to the US but we are continuously studying the market and looking for new opportunities. The all-new 2016 Optima midsize sedan is one of our best selling vehicles and at this time we are focused on its launch in the U.S." Now in prototype form, spy photographers caught engineers testing the Sportwagon out on German roads. The roofline declines as it makes its way to the back, a nod to the concept and a sporty profile. Otherwise design matters appear quite toned down compared to the concept, which shouldn't be a surprise. And in spite of commenters who promised Kia their money if the South Korean automaker would produce the Sportspace with all-wheel drive and something like 400 horsepower, what buyers will really be faced with is front-wheel drive and a 2.0-liter turbocharged engine with around 250 horsepower. A plug-in hybrid is said to be on the cards, too. Spy shooters said they saw Volkswagen Passat and Ford Mondeo wagons at the Kia test facility, so you know the benchmarks and have more proof that it's not for us. It's expected to make its production appearance at next year's Geneva Motor Show.

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.

Did Lexus make a BMW? Or did BMW make a Lexus? This and other 2017 surprises

It's that time of year again. The calendar is about to reach its end, Star Trek Cats 2018 is about to take its place, and I'm reflecting about all the cars that graced my driveway this year or summoned me to exotic places. You know, like Stuttgart or Phoenix. In 2017, I drove at least 57, and as I perused the list of them, I started to notice a common refrain: "This car surprised me." Most were pleasant surprises, but there were a few head scratchers and facepalms for good measure. In both cases, it was generally the result of car companies seemingly trying to break out of an existing mold. Nowhere was that more apparent than the pair of Lexuses slathered in Infrared paint: The LS 500 that left me this week and the LC 500 that was my favorite car of 2017. Though Lexus has been trying to shake its crusty, gold-packaged reputation for some time now, its efforts always seemed like an old man choosing Hollister to redo his wardrobe after realizing it hasn't been updated since 1987. I fell in love with the LC, genuinely floored by its near-perfect take on the GT. It's characterful in sound, appearance and tactility. It was at home in the city, in the mountain and on the open road. It was both comfortable and thrilling, and after driving the mechanically related LS 500, I can report that the LC's talents aren't an outlier. The LS 500's turbo V6 may make different noises than the LC's naturally aspirated V8, but it nevertheless invigorates the cabin when the car is placed in Sport+ mode. The steering is truly communicative, body motions are kept in miraculous check, and I absolutely forgot I was in an enormous luxury limo ... and a Lexus one at that. It was everything that the BMW 530e was not. I drove that on the exact same roads and was utterly bored the entire time. Generally doughy, lifeless steering, more distant than Planet 9. And no, the plug-in hybrid powertrain had nothing to do with that. At least it shouldn't. The Porsche Panamera S e-Hybrid I also drove this year proves that, as do the Hyundai Ioniqs, which are surprisingly adept and fun little cars regardless of what powers their wheels (Hyundai + hybrid = fun really blew me away). I would drive that Lexus LS F Sport over the BMW 5 Series any day of the week, which seems like a shocking thing to say in relation to either car. While Lexus is seemingly breaking out of its old crusty mold, BMW seems to be climbing into one.
