Hyundai Tech: Sonatas of Two Different Flavors

Hyundai is expanding its Sonata lineup seemingly with something for everyone. In honoring this South Korean company’s press embargo, I cannot share driving impressions just yet, but I can spill the technical beans. And there are lots of them.
The 2.0T Sonata, as its name suggests, is powered by a turbocharged 2.0-liter engine. Hyundai avoided the GDI moniker that could have legitimately been attached, as this inline-4 also features direct injection of its gasoline. Now I admit there’s nothing particular novel about having a turbo-enhanced direct-injected engine of small displacement do the job of a traditional—and more fuel-consumptive—V-6. But Hyundai engineers have been busy in perfecting this concept in several distinctly innovative ways.
For one, the turbo’s compressor housing is actually part of the engine’s exhaust manifold. What’s more, the casting that integrates these two elements is of austenite stainless steel. It’s quite a technical achievement to use this material, but it’s ideal for this application because of its thermal properties of getting exhaust heat efficiently to the turbo’s compressor. And, of course, having the two components integrated into one only enhances this.
Factoid: It’s both the kinetic energy of exhaust flow as well as the thermal energy of its expanding gases that drive the turbo’s compressor and its attached forced-induction-producing impeller. Hyundai’s integrated design enhances both aspects.
The Sonata’s turbo is a twin-scroll type as well. That is, its porting and vanes are designed to exploit two separate paths of exhaust flow, from cylinders 1 and 4 and from cylinders 2 and 3. This way, pulses during inherent four-stroke operation don’t trip over each other. This twin-scroll idea isn’t unique to Hyundai (the 2.0-liter Buick Regal uses it as well). But the Sonata’s 274 bhp versus the Regal’s 220 suggests the other wizardry involved.
Hyundai engineers figure that optimized forced induction plus direct injection are worth around a 22-percent kick in torque, from 220 to 269 lb.-ft. over a broad rpm range, with the twin scrolls accounting for perhaps half this. There’s lots of synergy involved here as well: Direct injection provides a cooler charge of fuel; optimized intercooling does its magic as well with the forced induction of air. They combine to produce the 2.0T’s 137 bhp/liter, a figure that’s quite amazing in a car in the $24K-$29K range. More details on this and my driving impressions once the embargo has lifted.
The Sonata Hybrid also carries some very neat tech, specifically in its parallel-hybrid drivetrain, lithium-polymer battery pack and optimized thermal management. Hyundai engineers also pointedly used the term “fun to drive” in describing their hybrid design and development.
Its 2.4-liter gasoline engine operates on an Atkinson Cycle; more correctly, like other hybrids, on a innovatively valve-timed simulation of this short-compression/long-expansion concept. A clutch separates this powerplant from a 41-hp electric motor which resides directly ahead of a 6-speed automatic transmission eventually sending twist to the car’s front wheels.
Note the difference between Hyundai’s hybrid layout and those of Toyota Camry, Ford Fusion or Nissan Altima (these three, certainly technical siblings in more ways than one). The Hyundai’s 6-speed automatic is in marked contrast to the other’s CVTs, one claimed benefit being enhanced highway performance. What’s more, as its operation is integrated with the electric motor’s, this automatic has no need for an energy-sapping torque converter.
Unlike these other cars’ nickel/metal hydride battery technology, the Sonata Hybrid’s is lithium-polymer. Newer technology, it offers improvements in everything from power and energy density to weight to volume to cycle life to characteristics of state of charge.
This last one, SOC, for short, is particularly interesting in Hyundai’s optimization of hybrid operation. For reasons of durability, any battery profits from gentle chemical action—not being discharged too deeply, not being charged to its full capacity, with SOC being a measure of this. Typical nickel/metal hydride batteries owe their life-of-the-car longevity to an SOC window as narrow as 15 percent; e.g., operating no less than 50 percent SOC, no more than 65 percent SOC. Hyundai engineers say lithium technology can accept a wider range, say 50 to 75 SOC, with no degradation of battery durability.
What’s more, innovative thermal management stretches this further: In cold weather, for example, the Sonata Hybrid’s SOC window can expand to as wide as 45 percent, from 45 to 90 SOC. One benefit of this is balancing the inherent loss of battery performance concomitant with lower ambient temperatures. Despite these exemplary SOC characteristics, Hyundai engineers expect to confirm battery longevity on the order of 250,000 miles or more.
A last example of Hyundai’s thermal management and efficiency. Compared with other Sonatas, the Hybrid has a larger air intake; this, to handle hybrid powertrain cooling in extremes such as Death Valley at summer’s peak. On the other hand, such a gaping snout is detrimental to aerodynamics. To optimize matters, the Sonata Hybrid has what engineers term an Active Air Flap. As its name suggests, this gizmo automatically adjusts the airflow. It’s wide open at low vehicle speed and high coolant temperature; it closes as speeds increase or coolant temperature drops. Engineers figure there’s a 10-percent reduction in CD with this, all the more impressive when you hear that the car’s inherent drag is an already low 0.25.
My driving impressions of the Sonata Hybrid can appear on October 18 (one day before my birthday—please, no presents).

2012 Hyundai Elantra Launched

At an introductory price of Rs 12.51 lakh (ex-showroom Delhi) for the base petrol version the Elantra isn't just gorgeous to look at, but offers top-of-the line comfort and convenience features, and is a major leap forward compared to its predecessor in almost every department


Hyundai Elantra launched


There and back again. The fourth generation Hyundai Elantra’s entry and early departure from Indian soil a few years ago was unfortunate but as we see it has proved to be a significant reality check for its Korean creator, who once again returns to the D segment battlefield but this time with a more able commander. And we are indeed smitten.


With the launch of its 5th generation Elantra, Hyundai hasn’t just earned more brownie points for its already successful fluidic design language but in a sense proved exactly how lethal an architecture it truly is in the form of this scrumptious looking sedan.



And the surprise doesn’t end there. Starting from the engine options on the new car, to its exhaustive features and premium interior fit and finish, the new Elantra packs in everything you’d expect from such a high-end passenger car and more.

First up are its 1,797cc petrol and 1,582cc diesel engine options, both of which are offered with a choice of manual or automatic transmission. The four cylinder petrol engine is capable of churning out a solid 149.5PS @6,500 rpm and a decent 181Nm of torque @ 4700 rpm.  The diesel unit is incidentally the same CRDi engine fitted into the new Verna that pumps out a decent 128PS @ 4000 rpm and a rather decent 265Nm of torque between 1,900-2,750 rpm.

Hyundai i30: nu al vernieuwd


Met de i30 zette Hyundai in 2007 een belangrijke stap. Het was de eerste Hyundai die in Europa van de band rolde, de eerste met de nieuwe naamgeving (de i-reeks). Na minder dan vijf jaar is de opvolger al klaar, die eerst als vijfdeurs op de markt komt.
Verkocht de eerste generatie i30 dan onder de verwachtingen? Helemaal niet. Jaar na jaar is de verkoop van de compacte middenklasser gestegen, tot 115.000 stuks in 2010. In totaal verkocht Hyundai al 350.000 exemplaren van de i30 tot midden 2011. De nieuwe i30 debuteert volgende week op de autoshow van Frankfurt. De vijfdeurs mag de spits afbijten, later volgen nog een driedeurs en break.
De nieuwe i30 werd in Europa ontworpen, maar zal internationaal verkocht worden. "De auto is ontworpen om de leiders van het C-segment te bekampen", zegt Hyundai. De Volkswagen Golf, Ford Focus, Renault Mégane en Opel Astra mogen dus hun borst nat maken. Een belangrijke troef is alvast het Five Year Triple Care-pakket (vijf jaar fabriekswaarborg, pechbijstand en gratis technische check-ups).
Het gloednieuwe design neemt heel wat kenmerken over van de i40. Hoofddesigner Thomas Bürkle: "De nieuwe generatie i30 is herkenbaar aan het Hyundai-familiegezicht met zeshoekige grille en de koplampen in de vorm van een juweel met onderscheidende dagrijverlichting. In het profiel van de nieuwe i30 loopt een sterke karakterlijn van voorste naar de achterste wielkasten, helemaal tot aan de achterlichten." Hyundai hoopt met deze look "jonge, progressieve kopers" aan te spreken en de uitstraling van het merk te verbeteren.

2012 Hyundai Veloster


To hear John Krafcik tell it, the 2012 Veloster is just another Hyundai. Allow us to rephrase that. According to the company's North American CEO, the searing Vitamin C orange coupe shown here is something we should've seen coming, the predictable end result of the relentless innovators at his Korean employer.

Yet to be fair, even now, "innovation" isn't exactly the first thing that comes to mind when we think of Hyundai. But perhaps it should be. After all, this is the same company that's led the way with radical customer relations plans like Hyundai Assurance (income loss payment coverage and buy-back, guaranteed trade-in values, etc.) and brash products like the 2011 Sonata, which passed on cylinders five and six in favor of forced induction – to say nothing of its unique hybrid variant and brave aesthetics. From marketing to product, Hyundai has rather quietly built a solid case for itself as an innovator.

And yet... even though we knew it was coming, we still weren't prepared for the Veloster. Aggressive family sedan styling aside, we haven't seen Hyundai allow its design team to so comprehensively stretch its creative legs as we have in this little four-door coupe. Did we say four-door? Indeed we did. Following hatchback naming conventions of three- and five-door bodystyles, this tangerine bolide is actually a four-door. It's got a conventional, longish driver's side door and a traditional lift-up hatchback. But stroll over to the passenger's side, and things get deeply funky – there's a second aperture behind a subtly shorter front door. We've seen similar setups like this in the past, a rear-hinged demi-door to ease access to a tight back seat, but this isn't a suicide solution. The Veloster employs a normal front-hinged rear door, albeit one with the handle hiding in the gloss black C-pillar.

The Veloster's styling is as idiosyncratic as its door configuration – there's just a lot going on. That's thanks to front lights shaped like Parasaurolophus heads and a gaping lower air intake and fascia whose gloss black elements look like they're trying to push their way out from inside the engine compartment. We could do without the faux hood vents, but presumably these are placeholders for the still-unconfirmed turbo model.

Prominent fender blisters shroud standard 17-inch wheels (18s are optional, including one design with unique body-color spoke inserts), and gloss black A-pillars combined with a tapering fixed quarterlight give the greenhouse a racy 'helmet visor' look. The beltline is high, with visual bulk curbed somewhat by a lilting cutline down by the rocker panel.

The rear end is... stubby. It has the same split-plane glass solution we've seen in other hatchbacks from the Lamborghini Espada to the Toyota Prius. But unlike those cars, the Veloster's vertical pane is larger than normal, and it's arched at the top to improve visibility. There's also a pair of unusual sheetmetal scallops that emanate from the rather globby taillamps and a strangely prominent rounded hatch-pull-cum-logo. Like the nose, there's also a gloss-black lower fascia that terminates neatly in a pair of handsome rounded rectangular exhaust finishers.

Simply put, nothing else on the road looks like the Veloster, and until they start popping up everywhere, you'll collect stares and finger points no matter where you go – even if you don't order yours in one of the Skittles-refugee paint selections. Is it pretty? Absolutely not. Unique? Uh-huh. Avant-garde? Unrelentingly. Its looks won't be for everyone, but we dig it.

Let's be clear – the Veloster is a little slip of a vehicle. At just 166.1 inches long, it's nearly eight inches shorter than a Scion tC, or about 5.5 inches longer than Honda's Lilliputian CR-Z, which doesn't have a back seat. It's also a comparative bantamweight, tipping the scales at as little as 2,584 pounds. That's not only lighter than its Japanese rivals, it's less than a Mini Cooper S (2,668 lbs) – a car that's nearly 20 inches shorter.

Given its light weight, you could be forgiven for expecting a cheap and bare-bones interior, but the Veloster's cabin is anything but. In fact, the level of standard equipment is nothing short of flabbergasting – especially for a car that starts at $18,060 (including $760 delivery).

The heart of the interior is the seven-inch LG touchscreen, which comes standard whether you pony up for navigation or not. The display governs everything from the base six-speaker audio system (which itself includes standard satellite radio, iPod input and Gracenote music identification) to vehicle settings and Bluetooth telephony. What's more, Hyundai has included an RCA cable so you can play videos from your smartphone or hook up a video game console when parked (a 115-volt outlet is optional). You can diddle with personalization settings like wallpaper, color schemes and varying welcome chimes, or opt-in to play fuel economy games that let you see how your performance stacks up against other Veloster drivers. No, we're not kidding.

That last bit is made possible by Blue Link, Hyundai's new embedded telematics system that doesn't require a tethered mobile phone. Like General Motors' OnStar, it's a subscription-based setup with tiered services. The most basic level, Blue Link Assurance ($79/year), bundles features like monthly vehicle reports with an SOS assistance button and automatic crash notification. The next Blue Link package up, Essentials ($179/year), keeps the aforementioned functions but adds services like remote door unlocking, advanced vehicle diagnostics, voice text messaging and location sharing through Facebook(!), along with a brace of safeguards like stolen vehicle slowdown, location and immobilization. There are even parental-minded items like speed alert, curfew alert and "geo-fencing," which will automatically text, email, or call when your little snowflake takes the car to a friend's house that they're not allowed to visit. If you pony up for the full-house Blue Link Guidance package ($279/year), it adds on services like traffic and weather, voice activated point-of-interest searches, restaurant ratings, and so on.

We simply didn't have time on our first drive to test – let alone master – all of Blue Link's capabilities, but what we did use was both self-explanatory and effective. We even called and used the turn-by-turn directions feature with on-screen instruction, and it almost makes the optional navigation system seem superfluous. Blue Link comes standard on all Velosters, and there's a free trial period so you can tinker around and see if you want to become a subscriber.

All of Blue Link's whizbangery would be for naught if the rest of the Veloster's cabin was a hateful place in which to spend time, but it's anything but. Controls are easy-to-reach, the steering wheel tilts and telescopes, gauges are clear, and we like the big, Honda Ridgeline-like grab handles on the doors. Overall, materials and switchgear are class appropriate or better and fit-and-finish is excellent. Our test cars issued nary a squeak or rattle – even over suburban Portland's ubiquitous neighborhood speed bumps. An optional panoramic moonroof floods the interior with light, and the standard all-cloth seats are comfy. (Leatherette accents in the buyer's choice of three colors are bundled with available tech and style packages).

That bonus rear door opens up to an unexpectedly usable rear seat, with plenty of knee and legroom, and enough headroom for sub-six-foot passengers to avoid claustrophobia, though taller friends will likely balk. The split-fold seatback isn't even overly vertical, and the bottom squab doesn't leave you eating your knees. The rear door is admittedly a bit on the smallish side, but it's certainly preferable to an even smaller rear-hinged door, as on the Mazda RX-8 – and not just because you won't get trapped in a parking space between two open doors. Negotiate the trunk's high liftover height, and there's even a surprisingly generous 15.5 cubic-feet of cargo space. How the hell did they cram all that in such a tiny footprint?


If there's an Achilles' heel with the Veloster's cabin, it's over-the-shoulder visibility (when merging onto a one-way street, for example). That plunging roofline and rear door handle arrangement makes for a massive C-pillar, and while the arched vertical glass allows for better-than-expected visibility directly behind, it can't help left or right of center. We recommend the available backup camera, but even that will only help with tight maneuvers like parking.

Omissions? You can't order heated seats, an oversight that Krafcik pledged to us he would fix by the end of the model year, and leather and high-intensity discharge headlamps, once-costly options that are now making their way to the shallow end of the market, aren't available either.

The Veloster's powertrain is no less unique than its exterior, with a 1.6-liter, direct-injected four-cylinder engine and the buyer's choice of a six-speed manual or six-speed dual-clutch transmission, Hyundai's first. We sampled both cogboxes at the Veloster's Portland, Oregon launch, and their gearing makes the most of the Gamma's meager 138 horsepower (at 6,300 rpm) and 123 pound-feet of torque (at 4,850 rpm). Acceleration is best described as adequately entertaining – we're ballparking 0-60 mph at about eight seconds. This is an 'eco-sport' proposition, not an all-out performance car – that's what the Genesis Coupe is for.

2012 Hyundai Veloster engine

We sampled a variety of different Velosters, and the six-speed manual is an able (if undistinguished) partner. However, we noticed some car-to-car variation in terms of clutch operation, none of which were quite as linear in action as we'd like. The self-stirrer is still a fun-to-drive setup and it's a long way from a deal-breaker, but we do wish the left pedal offered a crisper engagement point.

We also tried out Hyundai's new six-speed EcoShift dual-clutch gearbox ($1,250), and found it to be an agreeable piece of kit. Responsive and at least as refined as other DCTs in this end of the market (we're looking at you, Ford), it's easy to keep the engine on boil thanks to wheel-mounted paddleshifters that work even if the gearshift is left in Drive. We wish the paddles were a bit more substantial in size and feel, and that the transmission held gears at redline, but overall, it's hard to complain about the way this gearbox conducts itself, especially considering the gas mileage it generates.

Oh, did we mention the fuel economy? A six-speed manual Veloster nets 28 miles per gallon in the city and 40 mpg on the freeway (the DCT rings up 29/38). A manual CR-Z, by comparison, ekes out a three mpg edge in urban driving, but gives it all back on the freeway (31/37). We'll take that tradeoff every day of the week, especially as the Honda is smaller, heavier, adds hybrid complexity and costs thousands more.

2012 Hyundai Veloster shifter

If we had a single drivetrain nit to pick, it's with the sound – or rather a lack thereof. Hyundai is rightfully proud of the how quiet the Veloster is, claiming substantially lower wind and road noise levels than more expensive rivals; a particularly impressive feat of cabin isolation considering its extra door. But what sound that does come through from the engine and exhaust is uninspiring. While the Gamma isn't particularly raucous or coarse, it also isn't sporty. Hopefully Hyundai is leaving a more assertive soundtrack on the table for future variants, namely the aforementioned turbo.

The Veloster may ride atop a chassis derived from parts of the larger Elantra, but it's got its own tidier footprint. Despite being smaller, its wheels-at-the-corner stance not only helps maximize interior space, it lends the Veloster uncommonly neutral handling and commendable ride composure for such a small car. The chassis is rock-solid, thanks in part to lots of high strength steel (65 percent), a stiff rear substructure and dual center roof rails.

Suspension is basic but well tuned, with front MacPherson struts and a rear torsion beam with welded-in 23mm stabilizer bar (read: there will be no swapping in stiffer bars without considerable effort). Portland's roads are in pretty good nick (particularly the twisty bits that roll alongside the Columbia River), so we'll need to wait to get the Veloster back on the lunar surfaces of the Midwest to see how it handles rougher roads.

Despite its quick 14.2:1 steering ratio, with 2.88 turns lock-to-lock, the Veloster's electric power steering isn't quite as kart-like as the Mini Cooper, but it is smartly weighted and accurate, with no need for minor corrections on the freeway. In corners, our tester's optional 18-inch Kumho Solus KH25 all-seasons were quick to take a set and offered forgiving breakaway characteristics.

When it comes time to slow the front-drive fun, the Veloster has progressive-feeling four-wheel disc brakes (front: 11-inch vented / rear: 10.3-inch solid), along with a catalog of electronic bacon-savers (electronic brakeforce distribution, anti-lock, stability and traction control, etc.). And if it all goes pear-shaped, you've got six airbags and the aforementioned Blue Link safety net – provided you don't cheapskate-out after the free trial ends.

From where we sit, the 2012 Veloster stands as proof that, every once in a while, it's just good company policy to let your designers and engineers off the leash to indulge in a niche-model tangent. While the high-volume Sonata may stand as the car that put the world's automakers on notice, it's the Veloster's unbridled creativity – from its iconoclastic design to its in-car tech and gobsmacking value – that should really throw a scare into the competition's boardrooms.

If this is Krafcik's idea of "predictable," well, we can't wait to see what happens when Hyundai finally decides to shake things up.

Hyundai Veloster 2012 в России: стоимость и характеристики машины



Одна из самых горячих премьер на автомобильном рынке – спортивное купе от корейского концерна. Необычный дизайнерский ход, отличные ходовые характеристики Hyundai Veloster сулят ему первые строчки в рейтингах продаж. В центры этот автомобиль поступил в конце прошлого года, в России Hyundai Veloster начнет продаваться с 2012 года.
Первое, на что обращаешь внимание, – внешний облик.  Агрессивная решетка радиатора, мускулистые колесные арки, центрально расположенные выхлопные трубы, светодиодные фары – это не все сюрпризы. Машина примечательно и тем, что со стороны водителя у нее одна дверь, а со стороны пассажира – две: специально для захода на заднее сиденье. К слову, это разработка поможет и безопасности пассажиров.
Вместил в себя Hyundai Veloster 2012 года 6 подушек безопасности, климат-контроль, мультимедийную систему. Самый слабый мотор в комплектации – 1,6-литровый агрегат мощностью 140 сил. Здесь прямой впрыск топлива. Будет и турбоверсия с двигателем в 210 сил.  Коробка передач – и автомат, и механика.
Стоимость Hyundai Veloster – вполне сносная. Приобрести машину можно будет за 17 тысяч долларов. Правда, некоторые источники указывают сумму в 21 тысячу, а где-то и 24 тысячи. В целом модель еще как конкурентная. Ряд технических усовершенствований делает авто к тому же максимально современной.
