Shares of electric car company Tesla sank more than 6 percent on Wednesday after an Internet video showed flames spewing from one of the company’s vehicles near Seattle.
Shares of Tesla Motors Inc fell US$12.05 to US$180.95 — the stock’s biggest one-day decline since July 16.
The incident happened on Tuesday after 8am as the driver was traveling southbound on state Route 167 through Kent, Washington State Patrol Trooper Chris Webb said. The driver stated that he believed he had struck some metal debris on the freeway, so he exited the highway and the vehicle became disabled.
The driver told authorities he began to smell something burning and then the vehicle caught fire. Firefighters needed several attempts to extinguish the flames because the blaze kept reigniting, Webb said.
A trooper who responded to the scene was unable to locate any objects on the roadway, but Department of Transportation workers did observe some debris near the scene.
Webb said there was too much damage from the fire to see what damage the debris may have caused.
The automobile Web site Jalopnik.com posted photos of the blaze that it says were taken by a reader, along with a video. The video shows the front of the Tesla Model S in flames.
Tesla said the flames were contained to the front of the US$70,000 vehicle due to its design and construction. Company spokeswoman Liz Jarvis-Shean said there were no indications that the fire was caused by anything other than the crash.
“This was not a spontaneous event,” she said. “Every indication we have at this point is that the fire was a result of the collision and the damage sustained through that.”
Shares of Palo Alto, California-based Tesla have risen more than 400 percent since the start of the year. However, investors likely were alarmed, with some selling their shares, out of fear that the fire could be an indication of a flaw in the company’s battery packs.
The company’s battery system and the Model S itself have received rave reviews, including a top crash-test score from the US National Highway Traffic Safety Administration and a tie for the highest auto test score ever recorded by Consumer Reports magazine.
After getting the top crash test score, Tesla touted the Model S as being “the safest car in America.”
The car’s liquid-cooled 85 kilowatt-hour battery, mounted below the passenger compartment floor, uses lithium-ion chemistry similar to batteries that power laptop computers and mobile phones. Millions of such rechargeable batteries were recalled in 2006 and 2007 after it was discovered they could overheat and ignite.
Battery fires broke out in three Chevrolet Volt plug-in hybrid cars after crash-testing two years ago, but officials from General Motors Co and the US government believe the fires were caused by coolant leaking from damaged plastic casing around the batteries.
The New Taiwan dollar is on the verge of overtaking the yuan as Asia’s best carry-trade target given its lower risk of interest-rate and currency volatility. A strategy of borrowing the New Taiwan dollar to invest in higher-yielding alternatives has generated the second-highest return over the past month among Asian currencies behind the yuan, based on the Sharpe ratio that measures risk-adjusted relative returns. The New Taiwan dollar may soon replace its Chinese peer as the region’s favored carry trade tool, analysts say, citing Beijing’s efforts to support the yuan that can create wild swings in borrowing costs. In contrast,
Nvidia Corp’s demand for advanced packaging from Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) remains strong though the kind of technology it needs is changing, Nvidia CEO Jensen Huang (黃仁勳) said yesterday, after he was asked whether the company was cutting orders. Nvidia’s most advanced artificial intelligence (AI) chip, Blackwell, consists of multiple chips glued together using a complex chip-on-wafer-on-substrate (CoWoS) advanced packaging technology offered by TSMC, Nvidia’s main contract chipmaker. “As we move into Blackwell, we will use largely CoWoS-L. Of course, we’re still manufacturing Hopper, and Hopper will use CowoS-S. We will also transition the CoWoS-S capacity to CoWos-L,” Huang said
Nvidia Corp CEO Jensen Huang (黃仁勳) is expected to miss the inauguration of US president-elect Donald Trump on Monday, bucking a trend among high-profile US technology leaders. Huang is visiting East Asia this week, as he typically does around the time of the Lunar New Year, a person familiar with the situation said. He has never previously attended a US presidential inauguration, said the person, who asked not to be identified, because the plans have not been announced. That makes Nvidia an exception among the most valuable technology companies, most of which are sending cofounders or CEOs to the event. That includes
INDUSTRY LEADER: TSMC aims to continue outperforming the industry’s growth and makes 2025 another strong growth year, chairman and CEO C.C. Wei says Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), a major chip supplier to Nvidia Corp and Apple Inc, yesterday said it aims to grow revenue by about 25 percent this year, driven by robust demand for artificial intelligence (AI) chips. That means TSMC would continue to outpace the foundry industry’s 10 percent annual growth this year based on the chipmaker’s estimate. The chipmaker expects revenue from AI-related chips to double this year, extending a three-fold increase last year. The growth would quicken over the next five years at a compound annual growth rate of 45 percent, fueled by strong demand for the high-performance computing
