2021 L.A. Auto Show roundup | All the reveals, reviews, pictures

The L.A. Auto Show took place this week for the first time since the onset of the pandemic. It was a show packed with news and reveals, which hasn't really been the case with other shows we've seen this year, and Autoblog was on the floor covering every minute of it. Well, Riswick and Stocksdale were, anyway. The rest of us were sitting at home in our sweatpants, but hey, we'll take credit anyway. Let's get to it. Hyundai Seven Concept This is the Hyundai Seven Concept, and it’s meant to act as a preview for an incoming electric SUV for the Ioniq brand. It leans more toward the concept side of the spectrum than a production car, but expect the final SUV to take design cues from the Seven Concept. Kia Concept EV9 The Hyundai Seven counterpart isn't the only big, bold electric SUV at L.A. this year. Kia has its own take, and it's a modernized version of the traditional boxy utility vehicle called the Concept EV9. It also previews one of the next production electric cars for the brand, which should look right at home next to things like the Telluride. 2023 Kia Sportage HEV As promised, the 2023 Kia Sportage HEV has been revealed. The hybrid powertrain makes the compact SUV the most powerful version available, and it goes on sale next year. The engine is a turbocharged 1.6-liter four-cylinder paired with a 44-kW electric motor. Total output is 226 horsepower. The company didn't give a torque number, but it should basically be the same as the Sorento HEV that has the same basic powertrain: 258 pound-feet. Those numbers are a healthy step up from the 187 horsepower of the base 2.5-liter engine. 2022 Range Rover If you noticed how extra smooth and suave the new Range Rover looked during its recent reveal, Autoblog's James Riswick got a design tour that revealed some of the technological secrets to its success. "Less is more" is harder to achieve than it looks. Fisker Ocean Fisker has brought the new Ocean EV to the L.A. Auto Show, with a public preview at Manhattan Beach and a presence at the show itself. You can watch the public show reveal above, and see more shots from the show floor below. Fisker says the Ocean will start at $37,499 before incentives. That entry model would be the Sport trim with a single, 275-horsepower motor driving the front wheels and 250 miles of estimated range. It also has a 0-60 time of 6.9 seconds. 2023 Toyota bZ4X This is the 2023 Toyota bZ4X, due to hit U.S.

2021 Kia K5 fuel economy tops out at 32 mpg combined

In May, the EPA's FuelEconomy.Gov site listed three sets of initial fuel economy figures for the 2021 Kia K5, a move that helped confirm the end of the Optima name. The EPA has fiddled with the data set since then — the site doesn't list an all-wheel drive K5 anymore, for instance — but Kia has done us the favor of providing complete mpg numbers for every K5 trim except the flagship GT. The entry-level K5 LX with front-wheel drive gets 29 miles per gallon in the city, 38 on the highway, and 32 combined. This lines up with a model on the EPA site that's listed with stop/start on the 1.6-liter turbocharged four-cylinder. Most notably, the K5 LX sips a lot less fuel than the entry-level 2020 Kia Optima LX. The Optima LX houses a 2.4-liter four-cylinder with 185 horsepower and 178 pound-feet of torque — five horses up but 12 lb-ft down on the K5 — and gets 24 city, 32 highway, 27 combined. And the K5 only costs $100 more than the Optima. Among the competitive set, the in-house rival Hyundai Sonata in entry-level SE trim gives up one mile per gallon in the city to the LX, otherwise the two are equal. The Sonata SE, though, gets motivated by a 2.5-liter four-cylinder with 191 hp and 181 lb-ft. The Sonata SEL Plus with the same 1.6-liter as the Kia but costing $4,000 more returns 27 city, 36 highway, 31 combined. Outside the fold, the Toyota Camry ultimately evens out the fuel economy score in delivering 28 mpg city, 39 highway, 32 combined. The Honda Accord edges all comers with 30 mpg city, 38 mpg highway, and 33 combined thanks to its continuously variable transmission; the other three shift through eight-speed automatics. The front-wheel drive K5 LXS, EX, and GT-Line all return 27 mpg city, 37 mpg highway, and 31 mpg combined. The figures match a K5 model on the EPA site that omits the stop/start system on the 1.6-liter, but we can't see where Kia has mentioned a stop/start system in its K5 release materials. About 100 pounds difference in curb weight covers all four trims that we have info on so far. This would appear to indicate the lack of the fuel-saving tech on the three trims causing slightly lower fuel economy as opposed to extra luxuries weighing matters down. Only two trims for now come with the option of all-wheel drive, the LXS and GT-Line. When the K5 GT arrives, it will only come with all-wheel drive. Check the box to send power to all the wheels, and both variants deliver 26 mpg city, 34 mpg highway, 29 mpg combined.

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.
