2020 Hyundai Sonata shows fresh shape among competitors

The Hyundai Sonata received a refresh for the 2018 model year, but it seems that version won't be around for long, because a 2020 Hyundai Sonata midsize family sedan has been spied testing. The new car was spotted in Las Vegas testing alongside the competition. This new Sonata also appears to be a complete redesign, since nothing appears to be shared with the current model. Up front, the new Sonata looks much wider than the current model. Part of this is due to the headlights being moved to sit inline with the top of the grille, as opposed to slightly above on the current model. And while we can't see it clearly, the grille will likely have a similar shape to that of the current model and other Hyundais. The fenders also wrap around the top of the car more, further contributing to the car's wide stance. The profile of this new Sonata is different, too. It's a bit more traditional in how the engine compartment area doesn't blend into windshield as much. The current Sonata blends the engine, passenger and trunk compartments more. There's also a curve to the bottom of the greenhouse on the new car that lends the car a more graceful, less upright appearance. There is still a fastback look to the rear of the Sonata, but it's stretched out more, again helping the car look less upright. This is the first time we've seen the next-generation Hyundai Sonata, but it does look as though it's pretty far in development. What we can see of it appears to be production ready. As such, we probably won't have long to wait to see the car revealed. It will probably show up sometime next year in time for the 2020 model year. Related Video:

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.

Average new-car fuel economy figures continue record pace

Manufacturers are making more efficient cars and trucks; we've known that to be true for some time. Nearly every new car has some sort of trick to eke a few extra miles out of every gallon of fuel. Whether that be turbocharging, active aerodynamics or hybrid technology/electrified powertrains, the fact is that our vehicles are more efficient than ever before.
Thanks to a recent study by TrueCar, we've got fresh quantitative data to support the above statements. For the fourth month in a row, we've seen an improvement in national fleet fuel economy. We Americans are 0.7 miles per gallon more efficient than we were last month, and our cars are 1.6-mpg better than at this time last year. That said, we're still down on 2013's high, which was set back in January at 24.5 mpg.
Not only does this reflect the improved technologies in our vehicles, but it demonstrates a changing mindset among consumers, who are purchasing more efficient vehicles despite the relative stabilization of fuel prices. Every fuel-efficient model sold drives its manufacturers fleet average up.
