Hyundai beefs up HB20 R-Spec in Brazil

If you've been following the news from the Sao Paulo Motor Show, you'll likely have seen not only a series of new concept cars, but also a whole mess of production vehicles you never knew existed because they were developed specifically for the Latin American market. One of them is the Hyundai HB20.
Hyundai Brasil makes the HB20 in Sao Paulo for local consumption in three forms: there's the HB20 hatchback, HB20S sedan and HB20X crossover. It's the former which it has transformed into the R-Spec concept you see here.
Decked out in matte blue, the HB20 R-Spec concept packs an aggressively upgraded aero kit, extra cooling ducts, 17-inch alloys, LED headlights and an interior with leather trim and striped seats. Even if we don't know what's under the hood, it all looks pretty convincing, and makes us wish Hyundai would offer it Stateside as part of the Accent family with which it shares its underpinnings.

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.

Hyundai bets big on crossovers sporting diesel, electric, hydrogen powertrains by 2020

Hyundai announced a very aggressive crossover strategy for the next couple of years, with a total of eight vehicles launched between now and 2020. One of those is the already revealed sub-compact Hyundai Kona. The other seven crossovers range in size and fuel types, and Miles Johnson at Hyundai confirmed to us that all of them will be coming to the U.S. The first to launch is the aforementioned Kona, coming in early 2018. Also coming early that year is an unnamed hydrogen fuel cell vehicle. This hydrogen crossover will likely be sized and styled similarly to the FE Fuel Cell Concept shown at this year's Geneva show. A previous report about the production version stated that it would have a range of about 360 miles. Later that year will be two unnamed crossovers without any indication of size. They will also be joined by an electric crossover. In 2019, Hyundai has three crossovers planned for release. Early in the year will be a diesel-powered crossover. Hyundai gives no indication of what segment it would compete in, but so far we've only seen diesels in compact crossovers such as the Chevy Equinox diesel and upcoming Mazda CX-5 diesel. Mid-year will welcome a midsize crossover, and the year will be capped off with an A-segment crossover. Johnson also confirmed that this A-segment crossover will be smaller than the Kona. It could be an outright replacement for the Hyundai Accent hatchback, which did not return to the U.S. with the new sedan. Though we don't have much information regarding the unnamed and unspecified crossovers in the plan, Johnson did confirm that some of the crossovers in this rollout will include redesigned versions of existing offerings. This may include a new Santa Fe and Santa Fe Sport, or whatever the Santa Fe Sport will become. The company has previously stated that the Santa Fe Sport will be resized and probably renamed, and the regular Santa Fe would be larger the next time around. These changes would also make room for another small to midsize crossover.
