Now 11 seasons in, Formula E has come a long way from its sometimes-chaotic early days and those mid-race pitstops to change cars. Car swaps went away a long time ago, but when the series gets back to racing next month in Jeddah, Saudi Arabia, the mid-race pit stop will be back. Except this time, the cars will be quickly recharged by powerful 600 kW fast chargers.

The new race feature, which Formula E is calling "pit boost," is a 30-second pitstop, during which time the car receives a 600 kW fast charge—more than twice as much power as a Tesla Supercharger—that adds 10 percent (3.85 kWh) to the battery's state of charge. It's mandatory for every car in the race, but a team is only allowed to charge one of its two cars at a time, and only within a specified window of time during the race.

Some people are probably going to be unimpressed with the length of the stops—while they're shorter than you might see at a prototype stop at Le Mans or Daytona, you also won't see mechanics running around changing tires. We're also talking an order of magnitude longer than a current Formula 1 pitstop, which will no doubt be used as ammunition by Formula E's detractors, just as the lap-time comparisons are.

The Cadillac Lyriq was the first of a new breed of General Motors' electric vehicles. Built around a common battery platform (which used to be called Ultium), the midsize SUV has been on sale for about three years now, and for model year 2026, there's a new version available, the first Cadillac EV to wear the V-series badge.

"V-Series captures the spirit of Cadillac, embodying our relentless pursuit of engineering excellence through our racing and production vehicles," said John Roth, vice president of Global Cadillac. "LYRIQ-V takes this commitment a step further in the EV era, pushing our performance pedigree of V-Series to new heights with a powerful, personalized and high-tech driving experience that fits perfectly into our customers' lives," Roth said.

As with other Cadillac V-series cars, you can expect a much higher power output than the base models. In this case, that's a hefty 615 hp (459 kW) and 650 lb-ft (880 Nm)—not quite double the output of the single-motor Lyriq we drove back in 2023. The Lyriq-V uses a pair of motors to achieve that output, powered by the same 102 kWh battery pack as in the normal Lyriq.

Parents, students, teachers, and administrators throughout North America are smarting from what could be the biggest data breach of 2025: an intrusion into the network of a cloud-based service storing detailed data of millions of pupils and school personnel.

The hack, which came to light earlier this month, hit PowerSchool, a Folsom, California firm that provides cloud-based software to some 16,000 K–12 schools worldwide. The schools serve 60 million students and employ an unknown number of teachers. Besides providing software for administration, grades, and other functions, PowerSchool stores personal data for students and teachers, with much of that data including social security numbers, medical information, and home addresses.

On January 7, PowerSchool revealed that it had experienced a network intrusion two weeks earlier that resulted in the “unauthorized exportation of personal information” customers stored in PowerSchool’s Student Information System (SIS) through PowerSource, a customer support portal. Information stolen included individuals’ names, contact information, dates of birth, medical alert information, Social Security Numbers, and unspecified “other related information.”
