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.

2016 Hyundai Sonata Hybrid, PHEV gets conservative new look, more range

The plug-in hybrid middle ground between the 2015 Toyota Prius Plug-In (11 miles of EV range) and the 2016 Chevrolet Volt (50 miles) has long been the Ford domain. The Blue Oval has two plug-in hybrids with 20 miles of all-electric range, its 2015 Fusion and C-Max Energi Plug-in Hybrids. Entering this fray later this year will be the 2016 Hyundai Sonata Plug-In Hybrid, which will arrive with 22 miles of EV range and 93 MPGe. Hyundai made that announcement at the Detroit Auto Show this morning, saying that 22 miles is "farther than any other midsize PHEV sedan." Those zero-emission miles will come from a 9.8-kWh lithium polymer battery and a 50-kW electric motor. Once the pack runs out, Hyundai expects the PHEV to get 40 mpg combined (as well as 38 mpg city and 43 mpg highway) thanks to the gas-powered heart of the powertrain: a 154-horsepower, 2.0-liter Nu GDI four-cylinder engine that puts out 140 pound-feet of torque. When combined with the motor, the total system output is 202 horsepower. Hyundai is also showing off a non-plug Sonata Hybrid, which is expected to get a 10-percent fuel economy boost. The current version gets 38 mpg, combined, so that hints at around 42 mpg on the sticker when the car arrives in dealerships. The plugless model has to make due with a 51-hp, 38-kW electric motor that offers 151 pound-feet of torque and a net power rating of 193 horsepower. The two new Sonata Hybrid models have their own, more aerodynamic front and rear fascias as well as "purposefully unique wheels" that help drop the drag coefficient to just 0.24. The PHEV has a unique grille and a charge port on the front driver's side. Both models will arrive in dealerships later this year.

2020 Kia Soul vs. subcompact crossovers: How they compare on paper

At 10 years old, the 2020 Kia Soul has entered its third, and potentially best, generation yet. To get here, it fought off other boxy hatchbacks such as the Scion xB and Nissan Cube. But now it faces all new competition: subcompact crossovers. They offer similar sizes, prices and flexibility as the Soul, but with a veneer of ruggedness. But the Soul is ready with its own rugged trim, the X-Line, plus the return of its powerful turbocharged variant. To see how the Soul stacks up to the fresh competition, we've compiled vital stats on all the tall hatches. Considering the prodigious size of the subcompact crossover segment, we've limited our selection to a few options that are similarly priced and sized to the Soul, and that offer a bit of funky styling. They include the Toyota C-HR, Nissan Kicks, Hyundai Kona and Honda HR-V. There are of course many more options, and you can create your own comparisons using our Compare Cars feature. (You can also check out our Mitsubishi Eclipse Cross comparison that includes a few larger choices). In the meantime, though, check out all the numbers on our selected vehicles in the chart below, followed by analysis after. Performance, fuel economy and drivetrains The crossover segment is diverse when it comes to powertrains, with all different displacements, induction systems and drive wheels. A surprising number of these supposedly rugged and off-road-oriented vehicles (at least more than normal cars) are front-drive only. These include the Nissan Kicks, Toyota C-HR and Kia Soul. But the Kona and HR-V offer all-wheel drive, with the Hyundai offering it on both engine options. Speaking of engine options, only the Kia and Hyundai have two possibilities, either a base 2.0-liter naturally aspirated engine, or a turbocharged 1.6-liter engine. The base engines have identical outputs of 147 horsepower and 132 pound-feet of torque, but the turbo engines differ. The Soul has 201 horsepower to the Hyundai's 175, but both make the same 195 pound-feet of torque. The Kicks, C-HR and HR-V all offer just one engine option, and they're all naturally aspirated. The Nissan's engine is the smallest and least powerful: a 1.6-liter engine making 125 horsepower and 115 pound-feet of torque. The HR-V is next with a 1.8-liter engine making 141 horsepower and 127 pound-feet of torque. The C-HR rounds out the trio at 144 horsepower and 139 pound-feet of torque from a 2.0-liter engine.
