EPA says it will more closely monitor fuel economy claims from automakers

The unintended acceleration brouhaha at Toyota led to the National Highway Transportation Safety Administration tightening the vise on recall procedures. Likewise, the fuel economy kerfuffle that blew up with Hyundai and Kia's admission of overstated fuel mileage claims could lead to the Environmental Protection Agency policing automaker assertions by performing more audits.
At least, that's what a senior engineer with the government agency said while in Michigan giving a talk, according to a report in Automotive News. What that actually means, however, is still in question. Just ten to 15 percent of new vehicles - something like 150 to 200 cars per year - are rested by the EPA to verify automaker numbers. The EPA's own tests include a "fudge factor" to adjust lab mileage for real-world mileage, and the agency still relies on automakers to submit data for tests that it doesn't have the facilities to perform. How much more auditing can the EPA really expect to do, or perhaps a more relevant question would be how much more accurate could the EPA's audits become?
The price of gasoline, the psychological importance of 40 miles per gallon to a frugal car buyer, an automaker wanting to further justify the price premium of a hybrid, all of these things contribute to fuel economy numbers that insist on creeping upward. Perhaps the senior engineer encapsulated the whole situation best when he said, "Everybody wants a label that tells you exactly what you're going to get, but obviously that's not possible. A good general rule of thumb is that real-world fuel economy is about 20 percent lower than the lab numbers." If the lesson isn't exactly 'buyer beware,' it's at least 'buyer be wary.'

Here are all the EVs with 800V charging available in 2024

As technology advances, electric cars are improving their fast-charging times. That means less time spent waiting at a DC public charger when you’re out on the road. While Level 3 chargers used to provide a maximum of 150 kilowatts of power, 350-kW chargers are become more common, making for super-fast charging Â… if your car is capable of taking advantage of it. So how do automakers improve the charging speed of their EV batteries? Some are turning to higher voltage, specifically 800V charging. What's the difference between 800-volt charging and 400-volt charging? So how does 800V charging improve upon the more common 400V EVs? Put simply, the higher the voltage, the less amperage (current) it requires to charge. In other words, with more voltage, you get more wattage (power, aka charge rate) from the same amperage (current). 800V architecture is also more efficient, with less electrical resistance, so it can use thinner cables and smaller, lighter components while needing less cooling. The tradeoff is that it is more costly, and guess who that cost gets passed on to. While automakers don't break down their pricing to show how much more you're paying for that 800V system, you'll just have to evaluate any potential purchases as a whole, and make your decision based on overall pricing of the vehicle. Thankfully, the 800V EVs on sale now are generally ones we like. Now, 800V charging capability doesn't necessarily mean an EV has 800V vehicle architecture. For instance, the GMC Hummer EV and Chevy Silverado EV operate at 400V, but with their dual battery packs, can switch to 800V when charging by temporarily connecting those packs in series. Currently, there are only a handful of EVs available with 800V charging. But if you are going to find yourself taking longer trips in your EV and using DC fast chargers more often, you might want to consider choosing one with this faster charging capability. With that in mind, these are the EVs available with 800V charging, either on sale now or coming in 2024. 800-volt EVs available in 2024 Audi E-Tron GT Chevrolet Silverado EV Genesis GV60 Genesis Electrified G80 Genesis Electrified GV70 GMC Hummer EV Pickup GMC Hummer EV SUV GMC Sierra EV* Hyundai Ioniq 5 Hyundai Ioniq 6 Kia EV6 Kia EV9 Lotus Eletre* Lotus Emeya* Lucid Air Lucid Gravity* Porsche Macan Electric* Porsche Taycan Ram 1500 REV* Tesla Cybertruck *Coming later in 2024 Green Audi Chevrolet Genesis GMC Hyundai Kia Lotus Porsche Tesla Electric Lucid EV charging

Hyundai Q1 profit triples, as it adjusts production due to chip shortage

  SEOUL — Hyundai Motor Co posted a first-quarter profit that nearly tripled to its highest in four years as people bought its luxury cars, but warned it would have to adjust production again in May because of a chip shortage. Unlike its rivals, the South Korean automaker staved off production halts in the first quarter, thanks to a healthy chip inventory. But the shortage, exacerbated by factors including a fire at a chip factory in Japan and storms in Texas, is now catching up with Hyundai. Hyundai, which has lagged its rivals in the electric vehicle (EV) race, also said on Thursday that it was developing solid-state batteries and planned to mass produce EVs using solid state batteries in 2030. In February, Hyundai launched its Ioniq 5 electric midsize crossover, the first in a planned family of EVs that it hopes will propel it into the third rank of global EV makers by 2025. Hyundai Motor and Kia together aim to sell 1 million EVs in 2025. In the quarter ended March 31, Hyundai was unscathed as people at home and the United States snapped up its high-margin sports-utility vehicles and premium Genesis cars as the coronavirus pandemic dragged on, fueling car ownership. Net profit surged 187% to 1.3 trillion won ($1.16 billion) from 463 billion a year earlier, when business slumped as countries shut down to limit the spread of the coronavirus. This was in line with an average Refinitiv SmartEstimate. Revenue rose 8.2% to 27.4 trillion won. Hyundai is expected to report net profit of 1.4 trillion won for the April-June period, up 536% from the corresponding period a year earlier, Refinitiv SmartEstimate showed. Hyundai affiliate Kia Corp reported operating profit of 1.1 trillion won for January-March, up 142% on the year. Hyundai, which together with Kia is among the world's top 10 automakers by sales, has temporarily paused production three times since the beginning of this month and saved chips for its most popular models. "The condition of semiconductor parts is being a little more prolonged than we expected," said Seo Gang-hyun, an executive vice president at Hyundai. "As the semiconductor procurement condition is rapidly changing, it's difficult to predict production status after May.
