2014 Hyundai Tucson gets DI engines, styling tweaks, priced from $21,450*

Despite being overhauled for the 2010 model year, not much attention has been paid to the Hyundai Tucson crossover in recent times. But when its overseas twin, the ix35, received modest updates at this year's Geneva Motor Show, we knew it'd only be a matter of time before the US-spec model was blessed with similar tweaks. So, without further ado, meet the ever-so-slightly enhanced 2014 Tucson.
The most significant mid-cycle change is found under the Tucson's hood, where two new direct-injected four-cylinder powerplants are found. On the base end, there's a brand new 2.0-liter "Nu" inline-four, good for 164 horsepower and 151 pound-feet of torque. These numbers represent a loss of one measly horsepower, but five more foot-pounds of torque. Nothing significant here, and fuel economy is only slightly better - 23/29 miles per gallon city/highway versus the 22/29 rating of the 2013 model. Uplevel Tucson models use a revamped 2.4-liter engine, also featuring direct injection, which produces 182 hp and 177 lb-ft of torque - gains of six hp and nine lb-ft, respectively. That said, fuel economy for the front-wheel-drive, automatic transmission model has actually suffered some - 2013's rating of 21/30/25 mpg (city/highway/combined) has fallen slightly to 21/28/24. Both front- and all-wheel drive are available on all trim levels.
As far as visual enhancements go, the 2014 Tucson now uses projector-beam halogen headlamps up front and LED taillamps out back, and redesigned 17- and 18-inch alloy wheels are fitted, depending on trim level. Inside, two new cabin colors are available - beige and brown - the navigation system has been enhanced with a choice of two touchscreen interfaces, and there are now two-stage reclining rear seats.

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 recalls 205,000 Elantras for possible power steering failure [UPDATE]

UPDATE: Autoblog reached out to Hyundai spokesperson Jim Trainor for more information about this recall. He let us know via email: "Owners will be notified beginning in the second quarter." Also, there have been "no accidents, injuries nor fatalities," as a result of this issue. Hyundai is recalling 204,768 examples of the 2008-2010 Elantra sedan and 2009-2010 Elantra Touring because of possible failure of the electrically assisted power steering. The problem in these vehicles is that the ECU for the power steering can "sense a discrepancy in the steering input signals and, as a result, disable the steering power assist," according to documents submitted to the National Highway Traffic Safety Administration. If this happens, then drivers could suddenly experience a more difficult time driving the Elantras. According to a chronology submitted to NHTSA (that you can read in full as a PDF, here), Hyundai first became aware of this problem in 2010 and issued a TSB for it in 2011. At that time, just 0.25 percent of sedans and 0.36 percent of Touring models were shown to have the fault. However by October 2014, the issue had gotten worse, and 1.3 percent of four-doors and 1.9 percent of the hatchbacks were exhibiting it. The automaker believed that by maintaining manual steering the vehicles were still within the law, but "the industry has increasingly handled similar issues through safety recalls." In most cases, turning the ignition off and then back on rectifies things, but to fix this, Hyundai is updating the power steering control unit on these models. RECALL Subject : Electric Power Steering Assist may be Disabled Report Receipt Date: FEB 23, 2015 NHTSA Campaign Number: 15V100000 Component(s): STEERING Potential Number of Units Affected: 204,768 All Products Associated with this Recall Vehicle Make Model Model Year(s) HYUNDAI ELANTRA 2008-2010 HYUNDAI ELANTRA TOURING 2009-2010 Details Manufacturer: Hyundai Motor America SUMMARY: Hyundai Motor America (Hyundai) is recalling certain model year 2008-2010 Elantra vehicles manufactured June 1, 2008, to April 30, 2010, and 2009-2010 Elantra Touring vehicles manufactured November 1, 2008, to April 30, 2010. The electronic power steering (EPS) electronic control unit (ECU) may sense a discrepancy in the steering input signals and, as a result, disable the steering power assist.
