Shares in South Korean chipmaker SK Hynix tumble on US tariffs
SEOUL (Reuters) -Shares in South Korean chipmaker SK Hynix fell 3.1% in early Thursday trade, after President Donald Trump said the U.S. will impose a tariff of about 100% on chips. SK Hynix supplies Nvidia with chips called high-bandwidth memory used in artificial intelligence chipsets. Trump said on Wednesday the United States will impose a tariff of about 100% on semiconductors imported from countries not producing in the U.S. or planning to do so. But it would not apply to companies that had made a commitment to manufacture in the U.S. or were in the process of doing so. South Korea's trade envoy said on Thursday that SK Hynix and rival Samsung Electronics would not be subject to a 100% U.S. tariff on chips.

Chevy Just Set An Insane EV Range Record—In A Big Truck
Chevy Just Set An Insane EV Range Record—In A Big Truck originally appeared on Autoblog. No hardware or software changes were required to set a new record It's been a record-breaking month for Chevrolet. Already, the company set a new record for American cars at the Nürburgring with the Corvette ZR1 and ZR1X. Its latest record won't be as exciting for gearheads, as it involves the longest range on a full charge for an EV, but it's another stellar technical achievement. 300 miles is generally accepted as the psychological mark of a useful EV range, but Lucid far surpassed this by hitting 749 miles in the Air sedan last month—a record at the time. Chevy has now crushed that figure, and even more impressively, it pulled off the feat with a heavy, full-size pickup, not an aerodynamic 1,000 Miles On A Full Charge The record-breaking achievement came behind the wheel of a 2026 Chevrolet Silverado EV Max Range Work Truck, which went 1,059.2 miles on a full charge, breaking Lucid's 749-mile record. This truck is rated by the EPA for a 493 mile range, so how was it able to more than double that figure? GM says the record attempt began with a casual conversation between GM engineers late last year. They started guessing what sort of range they could achieve if the pickup could be optimized for range and efficiency. 'Getting this kind of range on a full charge doesn't happen by accident,' said Kurt Kelty, VP, battery, propulsion, and sustainability. 'It takes deep integration across battery chemistry, drive unit efficiency, software and vehicle engineering—and that's exactly what the team delivered. This achievement is a great example of how far our EV technology has come, and the kind of innovation we're building on every day at GM.'Real-World Test Sees Staggering Results The GM team performed the record-breaking test on public roads in southeastern Michigan, close to GM's Milford Proving Ground. The team optimized every feasible aspect of the truck, but left the hardware and software as is. While it's technically possible for owners of the truck to put some of these optimizing measures in place, combining them all will be just about impossible in normal driving. These were the measures taken by the team: When conditions allowed, drivers averaged 20 to 25 mph, and hard braking was minimized No passengers were in the truck for most of the test Windshield wiper arms were set to the lowest possible position, reducing drag The highest acceptable tire pressure was used, resulting in lower rolling resistance The wheel alignment was optimized and the spare tire was removed The climate control wasn't used at all For smoother airflow, an accessory tonneau cover was added The test occurred in warmer summer conditions None of these measures are particularly groundbreaking, but the cumulative effect clearly made all the difference. The various engineers who drove the truck did so in one-hour shifts, allowing them to incorporate the project into their normal work schedules. 'If we drove it downhill the whole time, sure, we'd get insane mileage,' said Jon Doremus, propulsion calibration engineering manager. 'But that's not what this was about. We wanted this to be real, on public roads.' The test suggests that by incorporating just a few of these measures, owners of this Chevy pickup should easily be able to squeeze over 500 miles of range from it, a commendable effort. The EPA rating of the Chevy is already better than all other rivals, including the Rivian R1T, Tesla Cybertruck, and Ford F-150 Just Set An Insane EV Range Record—In A Big Truck first appeared on Autoblog on Aug 6, 2025 This story was originally reported by Autoblog on Aug 6, 2025, where it first appeared.

South Korea trade envoy says Samsung, SK Hynix will not be subject to 100% US tariffs on chips
SEOUL (Reuters) -South Korea's top trade envoy Yeo Han-koo said on Thursday that chipmakers Samsung Electronics and SK Hynix will not be subject to 100% U.S. tariffs on chips. Yeo said on radio that among various countries South Korea will face the most favourable U.S. tariff rates on chips under the trade deal between Washington and Seoul.
