GM Will Launch a More Powerful V-8 Engine In 2027
Most of the time, when car companies announce major investments, the money goes toward electrification. But not today. General Motors is spending $888 million at its Tonawanda site in Buffalo, New York, to develop a sixth-generation V-8 engine. It's the largest single investment the company has ever made in an engine plant, a stark departure from an otherwise EV-focused auto industry. In return for the investment, New York will offer as much as $16.96 million in tax credits.
GM plans to deploy the new engine in full-size trucks and SUVs starting in 2027 and promises more power. While it hasn't provided specific figures, the current 5.3-liter V-8 produces 355 hp and 383 lb-ft (519 Nm) of torque. The larger 6.2-liter V-8 delivers 420 hp and 460 lb-ft (623 Nm), and the supercharged

The added power won't come at the expense of efficiency. GM says it can reduce fuel consumption and emissions through 'new combustion and thermal management innovations' aimed at developing a cleaner V-8. It hasn't confirmed whether any form of electrification will be involved, so the engine may remain purely gasoline-powered.
Tonawanda will be the second engine plant to produce the new V-8. In early 2023, GM announced a
$579 million investment
at its Flint Engine Operations in Michigan to assemble the sixth-generation engine and machine its block, crank, and head. At the same time, GM committed $12 million to its Rochester Operations facility in New York for intake manifolds and fuel rails, and another $47 million to Defiance Operations in Ohio for block castings.
By launching a new V-8 in 2027, GM signals its intention to keep the eight-cylinder engine alive in its largest vehicles well into the 2030s. Still, the company maintains its pledge to go all-electric by the middle of the next decade. It's a goal first announced in 2019 and reaffirmed as recently as October 2024. However, GM has left the door open for gas-powered vehicles beyond 2035, with CEO Mary Barra noting that the company wants to "be responsive to where the customer is."
Looks like America wants V-8s.

My favorite travel charger doubles as an AirTag. It just dropped to the lowest price yet
Last fall, I ditched the AirTag I previously used in my suitcase for this nifty travel charger and item finder combo from Twelve South. Since then, it has come in handy for several trips, offering peace of mind on top of its USB-C charging capabilities. This accessory couldn't have gone on sale at a better time either. CNN Underscored is kicking off its Summer Travel Week, and now Amazon has dropped prices lower than ever on both versions of the Twelve South PlugBug. Twelve South PlugBug 2-Port 50W USB-C Charger With Find My Equal parts AirTag and wall charger, this 2-in-1 device can track your luggage on the way to a destination, then power up your iPhone or MacBook once you arrive. It features a 50W output and a pair of USB-C ports and is now down to its lowest Amazon price yet. Twelve South PlugBug 4-Port 120W USB-C Charger With Find My Not as steep of a discount as the two-port version, this 120W charger packs the same Find My technology into a more capable wall adapter that's better suited for refueling all your gadgets at once. This is the model I use, though I think most will find the 50W alternative is a better value. Back in November, Twelve South launched its newest models of the PlugBug. These new editions are geared toward travel, with a suite of features that make them perfect for stowing in your carry-on or checked luggage. The most essential of which is the bundled modules that let you switch between a US-style wall adapter and plugs to use internationally. In the box, there are travel adapters for use here in America, as well as in Canada, Australia, Europe, the United Kingdom and Korea. Alongside being able to use these chargers just about anywhere in the world, Twelve South also added Find My tracking. Find My is the same technology that you'll find in Apple's beloved AirTags, meaning that this wall adapter pulls double duty as an item finder. So, instead of having to buy a separate accessory to track your checked bag, you can monitor the suitcase's location thanks to the travel charger you're already packing. All that earns it a spot on my list of the best portable tech. CNN Underscored has a team of writers and editors with years of experience testing, researching and recommending products, and they ensure each article is carefully edited and products are properly vetted. We consult top experts when relevant to ensure we are testing each product accurately, recommending only the best products and considering the pros and cons of each item. Senior deals editor Rikka Altland has personally reviewed tech for years and in the consumer electronics world for nearly a decade. Through almost that entire tenure, Twelve South has won her over time and time again with its inventive and useful gadgets. She recently put the company's AirFly Pro 2 to the test.

Apollo's John Zito Sees AI Boom Powering Private Credit Growth
Rapid-fire advancements in artificial intelligence make even predicting what next month will look like a challenge. That uncertainty is an opening for private credit, which has the adaptability needed to fund the fast-growing industry, according to John Zito at Apollo Global Management Inc. 'Being able to underwrite a 15- to 20-year loan, with flexible terms, with a hyperscaler, grid provider or power company — that doesn't get talked about enough in private credit,' Zito said during a panel at Moody's Credit Frontiers 2025 conference Tuesday in New York City.

The McDonald's Snack Wrap is returning next month
McDonald's is bringing back a long-requested, cult favorite food item: the Snack Wrap. 'It's back,' the company said in a two-word statement Tuesday, echoing the words of another Chicago symbol, Michael Jordan, in his NBA comeback fax. The wrap will return to McDonald's menus on July 10 as the company struggles to turnaround a sluggish start to the year. It's a simple formula: Chicken, lettuce, cheese and a tortilla. The fast food giant removed Snack Wraps from its lineup in 2016 after franchisees reportedly complained they were too complicated to make. However, some locations continued to serve the wraps until 2020 when McDonald's eliminated the item completely. The opening in the snack wrap market allowed competition to jump in, such as Wendy's grilled chicken ranch wrap in 2023 (at the time, its global chief marketing officer told CNN the chain 'didn't want to mess around with a McBland snack wrap dupe.') But fans never forgot the original Snack Wrap. A petition to bring the item back to menus has almost 19,000 signatures, with fans signing on as recently as two months ago. 'To my beloved McDonald's Snack Wrap… you were the ideal snack, the perfect meal on the go, the comfort food I didn't know I needed until you were gone. McDonald's, why did you take away such perfection?' one petitioner commented. A rush of fans clamoring to get their hands on a returning favorite could provide a much-needed boost for McDonald's. In May, the restaurant chain reported a sales decline for the second straight quarter – its worst loss since Covid – as customers pulled back spending on purchases like eating out as they feel shaky about the economy. So McDonald's is going all out with the Snack Wrap hype. The company posted a more than 350-word X post, allegedly penned by a social media manager who 'made 486 decks on 'reasons why to bring back the Snack Wrap.'' Regardless if the post is entirely true, it did underscore how dedicated the fanbase is toward the Snack Wrap. 'Your endless comments, tweets, and posts were the fuel i needed to keep on going,' the post said. 'you created a movement.' CNN's Jordan Valinsky contributed to this report.
