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.

2019 Hyundai Veloster Turbo Quick Spin Review | Now with actual 'velo'!

Hyundai finally seems to be figuring out driving dynamics. You know, suspensions that don't become flummoxed after hitting a mid-corner heave. Steering that does more than simply exist. A general driving experience that you may actually remember. Indeed, I'm going to remember the 2019 Hyundai Veloster Turbo, the latest Hyundai group car to demonstrate newfound dynamic talents. Fully redesigned, it picks up its predecessor's funky mantle, bringing over its unique three-door count and unusual hatchback rear, but actually satisfies the "velo" bit of its name. The old car was a dud, this one is not. Well, at least in Turbo guise, as no amount of chassis improvements can make the base 147-horsepower version go anywhere with immediacy. The Turbo packs Hyundai's 1.6-liter four-cylinder with 201 horsepower and 195 pound-feet of torque. That's pretty much equal to the Honda Civic Si Coupe, as is its curb weight of 2,899 pounds. Though it doesn't sing the same melodically mechanical song as the Honda's, the Veloster's turbo four-cylinder nevertheless delivers a satisfying punch. It responds and feels like it belongs in a vehicle with sporting intentions. On a mountain road, the new Veloster is capable, poised and legitimately fun. When completing my local mountain road evaluation route, I was compelled to turn around and run it again — the usual indication of a dynamic job well-done. This handling boon also doesn't come at the expense of ride quality. Sure, it's on the firm side, but it's also not crashy or tiresome relative other sporty compact cars. I'd be curious to try it with the Veloster Turbo R-Spec's manual transmission, though, as the regular Turbo's seven-speed dual-clutch automated manual lacks the precision and smarts of VW's DSG and other such transmissions. In Smart or Sport mode, it's not quick enough to respond to throttle or braking inputs, let alone anticipate the need for them. In manual mode, the engine oddly hangs onto revs when upshifting. The tachometer drops down to a lower rev count, but the engine continues to sing for a split-second. It's unusual. Though this transmission performed well enough in a compact crossover like the Kona, a wannabe hot hatch like the Veloster might be asking too much. That, however, is not why the Veloster ultimately left me cold. While it excels on a mountain road, it is merely OK everywhere else. It just isn't alive and involving enough to make mundane drives a joy — much as a Civic Si or VW GTI can.

Hyundai spotted testing Prius-style hybrid

The Toyota Prius has become an automotive icon – maybe less so among actual automotive enthusiasts than with the public at large – to the extent that most anyone on the street would recognize its five-door hatchback form and immediately identify it as a hybrid. Little wonder that Honda tried to emulate it with the second-gen Insight, but while that didn't work out so well for Honda, it looks like Hyundai is preparing to go down the same road with a dedicated hybrid of its own. Our paparazzi on the ground in the Arctic Circle have spotted this protoytpe and tell us what we're looking at is a new Prius-fighter from the Korean automaker. Snapped up high on a transporter truck, you can see the orange high-voltage cables underneath and a label with the letters AE HEV – the latter standing, of course, for Hybrid Electric Vehicle. We wouldn't be surprised if the AE stood for Advanced Experimental or Alternative Energy or something of the sort. Tipped to be based on the same platform as the next-generation Elantra, the new Hyundai hybrid is said to pack a 1.6-liter inline-four working in parallel with an electric motor juiced by a lithium-ion battery pack. It's expected to begin production in the second half of 2016, with a plug-in and possibly other variants to follow a year to a year and a half after its initial launch.
