Are you talking about Hyundai CVVT or CVVD?  It is 2 difference thing.

Honda got no VTEC engine nowadays except Type R.  For Type R, VTEC only on intake valve.

VTEC is no greater tech than Toyota VVT-I.

The best is combination of both found in Porsche VarioCam Plus.  4L NA produces 500hp at 9k RPM

Wait a min. The current L15B7 block still have VTEC heads right? At least the engine cover stll says so :D Normal L15B also have right?

But how is it different from the old iVTEC R18A and K20Z from 2006? iVTEC offers both phase and lift variable right?

I mean CVVT, apologies if I wasn't clear what I'm referring to...

Cos they are following the global tend of turbo charging their cars.

Does turbo charging preclude the use of valve lift? If anything it also contributes to either power or fuel economy... so if power isn't so much of an issue now then better fuel economy should be quite welcome I thought... also Honda still sells many cars without the turbo charging... so I thought having VTEC would still be very useful...

Hyundai CVVT is no difference from Toyota VVT-i. No sure Hyundai uses intake only or intake+exhaust.

CVVD will lengthen or shorten intake or intake/exhaust phase. Theoretically, CVVD and CVVT can be used concurrently.

Part of the reason is their silly Earth Dreams goal to reduce emissions from their car and delivering power output goals with smaller engines.

But hey, the reason why Honda has such a huge fan base is precisely because of their racing heritage.

I think I have seen dual CVVT somewhere on Hyundai cars or is it website... really not sure but that's the faint impression from my memory...

Yeah so I wonder possible to do CVVT, CVVD and variable lift - all three together or not... greater power and better fuel consumption all at once... ha ha... and also better emissions...

I was driving behind the Honda Mobilio and the back says i-VTEC... and I think the Accord and Odyssey also got that i-VTEC label... the Mobilio has a more advanced engine than the Civic???

No need so complicated.

Any 2 will be more than enough.

2020 Hyundai Sonata Hybrid: What to expect from its mpg-boasting solar roof.

source: https://www.greencarreports.com/news/1127957_2020-hyundai-sonata-hybrid-what-to-expect-from-its-mpg-boosting-solar-roof

Those who live in sunny climates—especially warm ones—see the shady spots in a parking lot as the hot commodity. But if more cars gain what the 2020 Hyundai Sonata Hybrid has—a Solar Roof System that can actually boost all-electric miles and gas mileage—frugal drivers might instead start hunting down sun-drenched spots for their potential to boost efficiency. 

Earlier this year, when Hyundai detailed the 2020 Sonata Hybrid and gave some first details regarding the solar roof, it sounded like a game-changer: potentially a couple of miles of extra engine-off distance from six hours out in the sun, and up to 700 “free” miles back per year. 

After four full days with the Sonata Hybrid—the top Limited version that includes the Solar Roof—my takeaway on the feature is that you should temper your enthusiasm, at least somewhat, if you live anywhere outside the Sun Belt. 

The test Sonata Hybrid, which was parked outside the entire time, without direct tree cover, accumulated an indicated 1.240 kwh—via the car’s trip computer readout that keeps a running total. The car had a total cumulative power generation of 7.225 kilowatt-hours, over its 1307 covered miles—with no baseline for where or how long it had been parked or driven prior to mile 1096. 

My experience will probably stand as something close to a worst-case scenario from which to frame the effectiveness of such a system. I had the Sonata Hybrid during a very gloomy, gray spring week—unusually so even for the Pacific Northwest this time of the year. The only sunny time happened to be the afternoon and morning before the Sonata Hybrid was taken back. And in one of those four-hour stretches of bright sun, from about 1 pm to 5 pm, we recovered about 0.200 kwh.

The solar roof is a first for Hyundai, and it has one big advantage over other solar-roof systems previously offered in the U.S.: It’s not just for the accessories. In the Sonata Hybrid, it will translate current either to DC for use by 12-volt accessories, for charging the 12-volt accessory battery, or for charging the hybrid system’s primary battery. 

According to Jerome Gregeois, senior manager for Powertrain and Eco Technologies at Hyundai, it takes a fairly sunny day for the system to produce the system’s rated 205 watts, but every little bit helps because once the system is producing 25 watts, or about 10 percent of what it can deliver, it’s getting meaningful energy into the battery systems.

The Panasonic 180-watt roof used in the Toyota Prius Prime does provide this functionality, but its availability has been limited to Japan; a 200-watt system in the Karma Revero was accessory-only.

The solar roof’s rating is at Standard Test Conditions, using an irradiance of 1000 watts per square meter and a cell temperature of 25 degrees Celsius, among other criteria. Hardware-wise, the roof is split into two actual solar panels—38.9 inches by 25.9 inches each—while a solar DC-DC converter converts voltage to the proper level (12 volts for the accessory battery or 310 volts for the hybrid battery) and charges one battery at a time until both are full. 

There’s another surprise advantage. Hyundai says that the solar roof weighs about 66 pounds, versus about 95 pounds for a panoramic roof that’s increasingly popular for top-of-the-line models. 

When the car is turned off but infotainment or climate control is on, the system can produce enough power to help keep the battery from discharging. 

Behind the scenes, solar panels such as those offered in the Sonata Hybrid also qualify as an “off-cycle credit” for Hyundai—a type of adjustment to its fleet-average emissions and fuel economy. The EPA states that the amount of the credit is “based on the rated power of the solar panels.” In this case that’s 9.0 grams per mile, according to Hyundai. 

One point to keep in mind is that—more than the mix of sun and clouds—your geolocation also has a lot to do with how much you’ll be able to claim from solar. Hyundai says that in West Hollywood, California, based on the toolset available from the NREL website, the energy from the system will add up to 309 kwh annually, or up to 1,236 miles—including a highly ambitious 4.0 miles per kwh assumption for the time the engine is off. 

Based on the map above, from the National Renewable Energy Laboratory, it appears that in Portland, in April, there’s less than half of the potential kwh per area per day than in Los Angeles. The set of solar resources from the NREL are a great starting point for being realistic about how much you might see back from such features. 

But to return and answer an initial question, yes, the solar roof could have boosted our mileage by a fraction of a mile per gallon and, based on napkin math, that fraction adds up.

Green Car Reports will have more in the next couple days on what the Sonata Hybrid was like to drive—and, perhaps more important to readers, whether we were able to approach its impressive fuel economy ratings in real-world driving. The Sonata Hybrid is EPA rated at 45/51 mpg city/highway (47 mpg combined) in its well-equipped SEL and Limited versions, versus 50/54 mpg city/highway (52 mpg combined) in its base Blue form. That’s mostly due to a significant weight difference that puts them in different EPA test classes.

Ultimately in the Sonata Hybrid what really matters is that it’s increasing awareness of solar as a viable supplement, in a car that the mass market will buy (and unlike Hyundai's plug-in hybrids will be offered in this form nationwide). We would guess that there’s a much harsher reality check due for companies like Sono Motors and Lightyear One, both of which claim significant amounts of normal driving in an EV to be recovered through solar. But when stops at the gas station are fewer and farther between, you can’t argue with free miles from the sun.

Hyundai-Kia and Genesis designs have been controversial of late. Will the design language change with his departure? To become more mainstream? Or continue to be controversial but in another direction?

Their design language of late are indeed controversial and much departed from the previous "fluidic sculpture" philosophy. It was probably done in line with the company's strategy to put a firm foot in the European market as a more mature brand focused on avant-garde design and driving, compared to it's (still) existing reputation of a manufacturer of cheap and reliable but plain as vanilla cars.

They seem to put their money where it is worth in the last decade, evidenced by the army of design (Schreyer, Donckerwolke) and engineering (Biermann) chiefs poached from VW Group and BMW respectively.

In a way, the current design has been rather well received in Europe. While the Sonata is not sold there, this Autogefühl review on the exterior and interior seemed pretty positive and the (German) presenter was quite impressed.

 

I do feel that they will carry this design language (Superman shield grille and all) into the next decade...

They have been boldest in design language and carrying that through to production models... and that's cos the designers they employed didn't have to hew to much tradition as the German brands they came from had to... so it was quite a blank canvas for them I would say... but all good things come to an end... hopefully some Korean designer can step up and take the design to the next level - global admiration...

Hyundai Sonata is the 'golden child' of Hyundai. The journey itself has been started since 1985 and continues to be given updates until entering the eighth generation. The taste presented this time looks very sensational combined with an aggressive face and various latest technologies

Check out this guy's 9 posts. All "say like never say" text. Is that a sign that he is some kind of bot?

Before the era of turbocharging, already no more VTEC.

Honda Civic Type R still have VTEC intake valve.

correction should be VTEC valve lift at exhaust valves. Not intake valve
