Hyundai returns to spark-compression engines with $5 million grant

Ed note: This version adds comment from a Hyundai spokeswoman. Hyundai said Monday it has won a grant worth $4.95 million from the U.S. Department of Energy to support research and development for an advanced, mixed-mode gasoline spark-compression engine, meaning the Korean automaker appears to be back at it in its quest to develop a fuel-efficient, low-emissions gasoline compression engine that can catch the likes of Mazda's Skyactiv-X. Hyundai says the three-year grant will leverage existing work with advanced valve train and previous DOE-funded technologies. Hyundai previously was working on its own HCCI — short for homogeneous charge compression ignition — project, developing a Gasoline Direct-Injection Compression engine with help from Delphi that used supercharging and turbocharging, a high compression ratio and fully variable valve train. But it has never come to fruition, reportedly due in large part to added costs. Hyundai spokeswoman Michele Tinson said the grant will support a new project for the automaker. "It's a departure from the past efforts forging a new direction forward for Hyundai where the fuel and engine combustion modes can be optimized to meet new targets," she said. Tinson said the GDCI project is completing its third round of DOE funding. Hyundai in December said it plans to release 38 environmentally friendly vehicles along with its affiliate Kia, and using a variety of technologies, by 2025. Hyundai alone will account for 18 of them. The aim is to use the spark-compression engines for conventional gasoline-powered vehicles, plug-in hybrids and mild hybrids. "The opportunity to explore mixed-mode engine technology through the DOE's grant signifies Hyundai's commitment to advanced research technology and compression engines," John Juriga, director of powertrain technologies at Hyundai America's Technical Center near Ann Arbor, Mich., said in a statement. "The co-operative research project along with Michigan Technological University and Phillips 66 signifies the importance in developing fuel and engine innovations that work together for optimal vehicle performance and leading fuel economy ratings." Mazda's Skyactiv-X compression-ignition engine uses Spark Controlled Compression Ignition to achieve diesel-like gains in fuel economy — about 20 to 30 percent higher than its current gasoline engines — and lower emissions from regular gasoline. It's said to debut in late 2019. Related Video:

Hyundai's Genesis G90 stretches out back home in Korea

Hyundai is getting serious about competing in the luxury market with the launch of its expanded Genesis line. And in the Far East it calls home, that means stretched limousines. Enter the new EQ900L. The Korean automaker's new luxury flagship stretches the wheelbase of the vehicle we now know as the Genesis G90 – or as the Equus in its previous iteration – by an extra 11.4 inches to give the top executives at Samsung and LG extra room to stretch out while in transit from the office to the Psy concert. The elongated cabin space also allows for first-class reclining rear seats, adjustable in 18 directions and upholstered in semi-aniline leather. A long center console runs the entire length of the cabin loaded with everything from ambient lighting to a Lexicon sound system. The same 5.0-liter Tau V8 still provides motivation, channeling 425 horsepower through an eight-speed automatic transmission to all four of the 19-inch wheels. That may not be enough to keep pace with the V12-powered Mercedes-Maybach S600 we get here, but it comes close to the S500 version sold overseas. Unfortunately for those of us living outside of Korea, the EQ900L is only being offered in its domestic market for the time being, where titans of industry can pick one up for 100 million won – equivalent to $84,000 at current exchange rates.

The greenest cars of 2024: Vehicles that use the least fuel and cost less to operate

All-electric vehicles may make headlines for environmental friendliness and fuel efficiency, but the “greenest” car in America in 2024 has a gasoline engine. According to the American Council for an Energy-Efficient Economy's annual GreenerCars ratings of the most environmentally friendly cars, the latest Toyota Prius Prime SE plug-in hybrid tops the list of greenest cars, although it's something of an anomaly, because battery-electric EVs follow it in spots two to five. Of the top 10 vehicles in the ratings, six are electric and four are hybrids: Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Toyota Prius Prime SE PHEV 71 $32,975 $529 2 Lexus RZ 300e EV 67 $55,150 $651 3 Mini Cooper SE EV 67 $30,900 $747 4 Nissan Leaf EV 66 $28,140 $741 5 Toyota bZ4X EV 66 $43,070 $689 6 Toyota RAV4 Prime PHEV 64 $43,690 $741 7 Hyundai Elantra Blue Gas Hybrid 64 $26,250 $864 8 Hyundai Kona Electric EV 63 $34,050 $695 9 Toyota Camry LE Gas Hybrid 63 $28,855 $907 10 Kia EV6 EV 63 $43,975 $689 11 Toyota Corolla Gas Hybrid 62 $23,500 $944 12 Hyundai Ioniq 5 EV 62 $41,650 $737 *ACEEE analysis using EIA data of annual cost—from gasoline, electricity, or a combination—of driving 15,000 miles The ACEEE also compiled two other vehicle rankings: the so-called “Greener Choices” and the “Meanest List.” The Greener Choices list includes a variety of high-scoring conventional vehicles, and the Meanest List identifies the worst-performing mass-market models. Finishing first in the “greener” list — which the organization says is about cars “available nationwide with among the lowest environmental impacts” — is the Honda Accord Hybrid. As far as the “worst-performing mass market” vehicle, that dubious distinction goes to the $184,000 Mercedes-Benz AMG G63. “ItÂ’s important for automakers to keep expanding affordable EV options rapidly so that the benefits of EVs are available to drivers across a wider spectrum of incomes as we transition away from cars that burn gasoline,” said Peter Huether, ACEEEÂ’s senior transportation research associate and lead researcher for the GreenerCars rankings. “For drivers whose needs are not met by todayÂ’s charging infrastructure, many efficient and affordable hybrid options are available.” Just over half the cars on the 2024 Greenest List start at under $35,000, including four EVs and three gas hybrids.
