This Boeing Powered Porsche Doesn't Have Wings But It Can Fly
Perhaps what's most insane is that this may not even be the only jet-powered Porsche 928 in existence. Member of the Porsche discussion forum Rennlist picked up on a red turboshaft-powered 928 back in 2008. Is the 928's V8 with its infamous timing belt so bad that it's more practical to swap in a helicopter engine?!
Jokes aside, it's unclear if the two cars are actually different iterations of the same car, or perhaps share the same builder. Besides differing in color, the red car has a single large exhaust port sticking out of the hood whereas the burnt orange example has its hood butchered for two smaller ports. Both cars appear to have spent time in Oregon, so perhaps there is, indeed, a connection. If you know, drop a comment down below.

One of the issues with running aeronautical propulsion in your P-car is that peak horsepower occurs at a ridiculous 28,000-plus rpm — not unlike this gas-turbine Firebird concept car. In this case, a reduction gearbox tamps that down to a more harnessable 5,950 rpm. Reportedly, the T50 Turbofan makes about 300 horsepower in this unusual application. That's perhaps less horsepower than one might expect from such a bodacious power plant, but it's still more than the 231 hp this non-S model 928 had when stock.
According to an Uncommon Classic Cars video that shows the Porsche running and driving, two batteries wired in series provide the 24 volts required get the beast started. The test driver also remarks that the hood-mounted exhaust stacks create an ethereal, wavy distortion in his line of sight. And oh yeah, the operating temperature is north of 1,000 degrees Fahrenheit.
Besides the elephant in the room under the hood, this 928 appears to be in pretty good shape. The paint is nice, it has larger-diameter (but mercifully original-equipment-looking) wheels, and the air conditioning is said to function. If small-block Chevy swaps like this 911 are too passé for you, this 130-decibel-generating 928 is for sale at Duncan Imports and Classics in Virginia. Admittedly, buyers don't seem to be beating down the door. It's been for sale for over a year, and the price has been slashed from $50,000 to a mere $29,747. That's definitely not the least expensive Porsche 928 on the market, but how many others can shoot afterburner flames from the hood?

Richard Hammond drives Porsche Cayenne EV prototype
Richard Hammond drives Porsche Cayenne EV prototype originally appeared on Autoblog. The days when automakers hid their camouflaged prototypes from the public are long gone. Last month, a prototype of the forthcoming electric Porsche Cayenne was entered in the Shelsley Walsh hill climb in the United Kingdom—and set a record. Now Porsche has revealed that the stunt was documented in a film shoot with former Top Gear and The Grand Tour host Richard Hammond. Hammond, who once rolled a Vauxhall Nova hatchback at Shelsley Walsh as part of a Top Gear episode, was given the Cayenne EV prototype for a quick review that was Sunday on the DriveTribe YouTube channel. The video is a little light on details, though, as the Cayenne Electric (as Porsche calls it) isn't scheduled to start deliveries until 2026, likely making it a 2027 model in the United States. One detail Porsche was willing to reveal was a maximum towing capacity of 7,716 pounds—the same as the current internal-combustion Cayenne. Hammond demonstrated that by towing a vintage Lagonda, estimated to weigh about 4,000 pounds with its trailer. Not surprisingly for a Porsche-sanctioned video, the Cayenne Electric prototype didn't seem to have any trouble with this task. Porsche also promises more power than any current Cayenne model, Hammond says in the video. That means it will exceed the 729 horsepower of the Cayenne Turbo E-Hybrid plug-in hybrid. Electric models will also be available with the Porsche Active Ride anti-roll system previously seen in the Taycan and Panamera. For the hill-climb runs, Hammond handed the Cayenne over to Gabriela Jílková, simulator and development driver for the Porsche Formula E team. Jílková covered the 1,000-yard course, which climbs a 16.7% grade, in 31.28 seconds, beating the previous SUV record by more than four seconds. She also covered the first 60 yards in 1.94 seconds, a time normally achievable only with purpose-built single-seaters on slick tires, Porsche claims. The Cayenne prototype ran on summer road tires. Porsche plans to bring the camouflaged prototype to the Goodwood Festival of Speed this month, but the automaker hasn't said when the camo will finally come off. When that time comes, the Cayenne Electric will take its place alongside standard gasoline and plug-in hybrid Cayenne models.

Stock Movers: Tesla, Tractor Supply, Core Scientific
Listen for comprehensive cross-platform coverage of the US market close as heard on Bloomberg Television, Bloomberg Radio, and YouTube with Romaine Bostick, Sonali Basak, Tim Stenovec and Emily Graffeo On this episode of Stock Movers - Tesla (TSLA) shares fell after Elon Musk announced he's forming a new political party, digging deeper into a pursuit that's been a drag on his most valuable business. The CEO announced over the weekend that he'll take on Republicans and Democrats with the 'America Party,' focusing on House and Senate seats for the next 12 months. After that, backing a candidate for president isn't out of the question, Musk wrote on X. Tesla's stock slid 7.4% as of 11 a.m. Monday in New York, wiping out $16.7 billion from his net worth, according to the Bloomberg Billionaires Index. If that drop were to hold, it would be the biggest decline for the shares since Musk's initial falling out with Donald Trump over the president's tax bill in early June. The stock has declined 28% this year as the CEO's politicking has hurt Tesla's standing with car buyers. -Tractor Supply Co. (TSCO) gains as much as 2.6%, rising to the highest intraday level since April, after adjusted sales observed by Bloomberg Second Measure rose 4.3% in the second fiscal quarter. The data draws from a sample of credit and debit card purchases made by US consumers. Analysts currently estimate revenue for the quarter of $4.4 billion, up 3.6% YoY. Bloomberg Second Measure observed sales have achieved high correlation with the company's reported revenue growth during the past five years. - CoreWeave (CRWV) is dropping $9 billion on the data-center operator Core Scientific Inc. in an effort to gain more direct control over the physical assets powering the artificial-intelligence boom. In buying Core Scientific (CORZ) in an all-stock deal, CoreWeave will inherit more than a gigawatt of data-center capacity across the US — much of which is already contracted out to serve its clients in training, deploying and using AI models. CoreWeave said Monday that controlling more of its supply chain will eliminate lease expenses, reduce costs including those associated with financing projects and 'future-proof' its revenue growth.

What Is An E-CVT And How Is It Different From A CVT?
The term "CVT", short for Continuously Variable Transmission, already confuses plenty of drivers, so naturally, automakers had to go and add a new twist. Enter the e-CVT or electronic-Continuously Variable Transmission. You've seen it in hybrid specs and maybe even heard it buzzing away under the hood of a Toyota Prius or a Honda Accord Hybrid. But here's the catch: it's not really a CVT in the traditional sense at all. A conventional CVT, uses belts or pulleys to offer an infinite number of gear ratios between low and high. The idea is smooth, efficient power delivery without any hard shifts. You rev up, and the car just, well, goes. No gear hunting, no shift shock, just a seamless ride. There are plenty of cars making use of it, and even some you may not know came with a CVT. An e-CVT, though, doesn't have pulleys or belts at all. It's an entirely different beast that lives mostly in hybrids, and instead of shifting physical gears with hardware, it blends the output of electric motors and a gas engine through software and planetary gears. Sounds fake? It isn't. But it's definitely different. Read more: These Are The Worst Transmission Recalls Of The Last 5 Years The biggest difference between a traditional CVT and an e-CVT is how they go about their job. Regular CVTs mechanically change the gear ratio using pulleys that expand and contract with a belt running between them. That's how they keep the engine in its ideal power band, balanced for fuel efficiency and smooth acceleration. Think of it like a very smart, infinitely variable bicycle gear. e-CVTs don't do any of that. Instead, they use a planetary gearset paired with two electric motors and an internal combustion engine. The system constantly analyses speed, driver input, engine power to select an optimal gear ratio for the conditions. The result is a setup with no belts or chains, thus greatly improving durability and reliability while being lightweight, although the system does require additional cooling. In Toyota's hybrid systems, for example, the internal combustion engine and electric motor work through a Power Split Device that determines where the power goes and when. It's Toyota's version of the e-CVT. If the e-CVT isn't even a CVT in the traditional sense, why does it act like one? The answer comes down to driving feel. Both deliver seamless acceleration and keep the engine at an optimal rev range to either improve efficiency or more power under load. To the average driver, it still feels like a CVT because that dreaded rubber band effect is still there since there are no traditional shift points of a conventional gearbox. So the revs may sound disconnected from road speed. But here's the kicker; because e-CVTs rely on electric motors and computer control, they're often more responsive than pulley-based CVTs. They're more fuel efficient, quicker accelerating, and better at mimicking the feel of a conventional transmission when they need to, with the possibility of built-in sequential shifting function. So the next time you hear someone dismiss an e-CVT as just another buzzkill transmission, you'll know better. It's not just a CVT, it's a whole different drivetrain game. Want more like this?
