IIHS says these are the safest cars of 2013

The Insurance Institute for Highway Safety (IIHS) has revealed its annual list of Top Safety Picks, an award that highlights automobiles it says offer "superior crash protection." A new and still more significant award, the Top Safety Pick+ honor, is given to those vehicles that earn good ratings for occupant protection in four out of five areas of measure. And while some 117 vehicles were given the TSP seal of approval for 2013, just 13 passed muster for TSP+.
To be fair, IIHS only evaluated 29 vehicles with its new testing procedures for TSP+ (we'd expect that the number of qualified cars will rise substantially for 2014). Luxury and Near Luxury midsize cars were the first groups evaluated, followed by midsizers in the Moderately Priced Cars category - unsurprisingly, it's only midsize cars that you'll find among the class this year.
Only two luxury sedans made the list of 13 for 2013: the Acura TL and Volvo S60. The other 11 cars on the list included entries from domestic, Japanese and German car makers: Dodge Avenger, Chrysler 200, Ford Fusion, Honda Accord (sedan and coupe), Kia Optima (but not its close kin, the Hyundai Sonata, strangely), Nissan Altima, Subaru Legacy and Outback, Suzuki Kizashi and the Volkswagen Passat all made the grade.

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.
