Mercedes-AMG's New Super Sedan Revealed: Insane Power, V-8 Noises
Mercedes-Benz's performance division hasn't had great luck straying from the tried-and-true V-8 formula. Its turbo-hybrid four-cylinder C63, while technically brilliant, was
largely panned
for its weight and lack of emotion. It's
currently selling
like whatever the opposite of hotcakes is, and even AMG CEO Michael Schiebe admitted the company '
could have better explained
' the car's powertrain to customers.
That said, AMG isn't taking any more
half measures
when it comes to electrification. On Wednesday, it unveiled the GT XX Concept, a 1,340-horsepower, 223-mph (360 kph) super sedan that previews AMG's first production EV, which is to be revealed next year. If AMG can back up its bold promises, this car should bring a serious fight to the Lucid Air Sapphire and Porsche Taycan Turbo GT, along with a healthy dose of AMG theater.

I previewed the GT XX Concept at a disused power plant in Rottweil, Germany late last month. While it's not a production car—evidenced by GT3 racing seats with five-point harnesses—AMG is adamant that the tech showcased here is production-ready, and will find its way into future models on the AMG Electric Architecture (AMG.EA).
The GT XX's looks won't be for everyone—the front three-quarter view calls to mind a surprised catfish. But from straight on, wearing the legendary C111 supercar's trademark shade of orange, there's no denying it's both imposing and unmistakably Mercedes. AMG claims a drag coefficient of 0.198 as it sits, an impressive feat for a car with wide tires and side-view mirrors. (The Lucid Air is currently the world's most aerodynamic car, at 0.197.)

AMG uses clever aero wheel covers to get to this number. Five carbon-fiber panels move outward and retract electrically as needed for brake cooling or optimal airflow. They don't draw power from the battery—AMG says the electric motors run off kinetic energy from the wheels' forward motion. Mercedes claims these wheels add 'one or two kilos' of weight compared to a standard wheel.
Inside the concept, we find carbon-fiber bucket seats with custom cushioning based on a customer's body scan. The textiles on the seats and interior trim are made from used GT3 race tires—we're told one tire provides enough material for an entire GT XX's hide. Orange trim and backlighting abounds, and in front of the driver, there's a large dual-tablet display and a yoke-style steering wheel with twistable selectors and paddle shifters (we'll get to that later).
Under the skin, the GT XX runs on an 800-volt architecture with a high-tech battery pack that can charge at 850kW over what AMG calls a 'wide range' of the car's charging curve. That's enough, it claims, to add nearly 250 miles (400 km) of range in about five minutes. That power makes its way to all four wheels through two electric drive units (EDUs) containing a total of three axial-flux electric motors: two in the rear and one in front. Total output is a whopping 1,340 horsepower, 106 more than the Lucid Air Sapphire's 1,234 but short of the Xiaomi SU7 Ultra's 1,548.

Those electric motors are tightly integrated into the EDUs, with each having its own planetary gearset and water-cooled inverter. The motors and gearsets themselves are oil-cooled. The rear EDU is the primary source of power, while the front EDU decouples while coasting and during steady-speed cruising for optimal efficiency. AMG claims the GT XX's direct-cooled cylindrical battery cells—a proprietary design whose supplier it wouldn't reveal—improve heat management and make it easier to sustain high-performance driving over, say, a track session.
Of course, this wouldn't be a proper AMG without some theater. Upon seeing the concept for the first time, we heard a V-8 soundtrack roar to life. Mercedes confirmed the car will have a simulated soundtrack, with AMG CEO Michael Schiebe quoting an unnamed executive as calling it 'the best V-8 we have ever developed.' Dual loudspeakers integrated into the headlight housings generate sound, and the housings themselves channel sound around the car. AMG's
promotional clip
and the presence of paddle shifters in the concept would lead us to believe there's a simulated gearbox of some kind, similar to the one in Hyundai's Ioniq 5 N.

Will the AMG GT XX make it to production? Some features, like the fluid light paint on the side skirts and the LED light bar on the rear, may not be worth the effort to get past regulators. But if the car's performance hardware is indicative of future AMG production models, the geeks from Affalterbach could put Lucid and Porsche on notice.
As I mentioned in my
brief test drive
of the upcoming Mercedes-Benz GLC, a model that's far closer to production than this one, it's an extremely challenging time to launch any new car, let alone a high-performance exotic. Assuming an AMG EV would be made in Germany, it would face 25% import tariffs in the US, in addition to price hikes on battery parts and supplies. What's more, the Xiaomi SU7 Ultra already matches most of the GT XX's wild specs and is on sale (in China) today.
Beyond the spec sheet, it's refreshing to see an automaker fully commit to a performance EV rather than hedging bets with a
hybrid
that weighs as much as a small house. Here's hoping we get an electric future filled with V-8 noises.

Verstappen hoping upgrades can boost title defence at Red Bull home race
Max Verstappen leads Red Bull into their home Austrian Grand Prix this weekend hoping a major upgrades package can boost his title defence before it is too late. The four-time world champion, who still needs to avoid any on-track problems that could lead to a mandatory race ban, has won four times at the high-speed Red Bull Ring circuit in the Styrian Alps and will be backed by his 'orange army' of fans. But he knows that combination may not be enough. McLaren's championship-leading duo Oscar Piastri and Lando Norris, who collided in Canada, are hoping to return to form after that rare off-day in a forecasted heatwave on a circuit expected to suit their car. Last year's winner George Russell of Mercedes, who took advantage of McLaren's struggles in Montreal to win with aplomb ahead of Verstappen, will arrive with momentum and optimism, if wary of the heat. "We are getting an update for Austria which will be refined for Silverstone," Red Bull's consultant Helmut Marko told Austria's Kleine Zeitung. "But if that doesn't work then it will be difficult for the championship –- as if it is not difficult enough already." Breaking free of team chief Christan Horner's more upbeat approach ahead of the 11th race of the 24-race season, Marko said he expected F1's cost cap and the need to focus on preparation for next year's sweeping regulation changes to curtail development this year. "At some point people will say 'That's it for further development and for two reasons -- time -- the production of new parts takes time –- and the cost cap." He suggested that a key decision to focus entirely on the 2026 car would likely be taken next month. Verstappen, whose Red Bull car has been unable to match McLaren for most of this year, is without a win in three races since the Emilia Romagna Grand Prix in May. He has won twice this season, at the high-speed Imola and Suzuka circuits, but struggled on slower tracks. In the drivers' championship, he trails McLaren's Piastri, by 43 points, and Norris, by 21, and is two penalty points on his licence away from a ban. Two of his current total will expire after this Sunday's race. - Red Bull's weaknesses - Horner conceded that "our weakness at the moment is in the medium-speed type of corner... and in Austria, in the middle sector, there's a bit of it there. We'll see. If it's hot, I expect McLaren to be stronger again. "There's a significant points gap between us and them, but we don't give up on anything and we're not even at the halfway point yet." In last year's race, Verstappen collided with Norris as they fought for the lead, gifting Russell his victory. That tangle, and his "stupid" crash into Piastri in Montreal, may hang heavily for Norris this weekend as he attempts to rebuild his title bid without further mishaps. With Russell confident and Mercedes also boosted by rookie Kimi Antonelli's maiden podium finish in Canada, a closely-fought contest is in prospect involving all the leading teams. "We expect our rivals to be much more competitive in Austria," said Mercedes team chief Toto Wolff. "The track should be a good test of our recent updates." Ferrari go into the weekend with less optimism. "For us, the best thing is to take it race by race, try to maximise," said Charles Leclerc. "It's been a disappointing first part of the season, but we keep pushing. Let's see where that takes us." str/jc

Toto Wolff Defends F1 Superiority, Slams Balance of Performance in Le Mans
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. While several F1 teams, such as Alpine and Ferrari, have fielded cars in the World Endurance Championship, Mercedes team principal Toto Wolff has explained why the German manufacturer has stayed away from the iconic Hypercar class of the 24 Hours of Le Mans. Mercedes parted ways with the Le Mans race after a major accident in 1999, where the car flipped dangerously after taking off at high speed due to aerodynamic problems. Currently, the team's presence is limited to the GT3 class. While Wolff acknowledged the glory of Le Mans, he revealed his bias towards F1, considering it is the top tier of motorsports. Despite declaring that all other forms of racing come second to F1, he addressed the possibility of returning to Le Mans on the Bloomberg Hot Pursuit podcast. He said: Toto Wolff, Executive Director of Mercedes AMG Petronas F1 Team on a scooter prior to the F1 Grand Prix of Saudi Arabia at Jeddah Corniche Circuit on April 20, 2025 in Jeddah, Saudi Arabia. Toto Wolff, Executive Director of Mercedes AMG Petronas F1 Team on a scooter prior to the F1 Grand Prix of Saudi Arabia at Jeddah Corniche Circuit on April 20, 2025 in Jeddah, Saudi Arabia."Le Mans... I'm a racer. The Le Mans 24 Hours is one of the greatest races in the world. "Formula 1, for me - obviously I'm biased - is the best there is. It's the best drivers, the quickest cars, the greatest tracks. But if I had to say what's next? Le Mans 24 Hours and the Indy 500. And then, for insiders, the Nürburgring 24 Hours. That, for me, is the top of the top. "What it is for me today is, we are concentrating on the main platform, and that is Formula 1. It's what we want to do. It captures 99% of the audience. Everything else comes second." Wolff then explained the hurdle that was preventing Mercedes from racing in Le Mans - the Balance of Power (BoP) rule, which prioritizes fairness in competition by ensuring all cars are as equal as possible within a class. He added: "As Mercedes, it's something that we've done in the past, but we weren't particularly... that wasn't our happiest place. "And then there's the little caveat to all this: at Mercedes, we are racing people. We don't like BoPs - we don't like Balance of Performance. We don't like somebody assessing your power, your energy consumption, your weight, your driver skill... "You spend so much time and money and effort developing the quickest car, and then you're being given 10 kilogrammes of ballast. I don't want that. I just want to build the quickest car." Wolff reckoned that a budget cap, like the one in F1, makes more sense to have a level playing field. He explained: "Formula 1 has shown how it should be done. Give us a cost cap. Do more of that - give everybody a cost cap. You cannot spend more than - whatever you said - 30-40 million. And within this 30-40 million, you can do what you want. I mean, there are still regulations, but nobody needs to bluff in pre-season testing or qualifying. It's pure racing. "If that were to happen, then Le Mans would absolutely be something we would look at. But at the moment, with BoP - having some officials judge whether you're too quick, adding 10 kilogrammes to your car or taking it out of someone else's the next day - that's not for us at the moment."

Mercedes-AMG's Wild New EV Packs 1,341 HP and Super Fast Charging
Mercedes-AMG is entering the world of high-horsepower electric vehicles and it's starting with a wild concept, the AMG GT XX. This four-door fully electric superlative on wheels is said to have a mind-bending 1,341 horsepower, a 223-mph top speed, and the ability to add 250 miles of range in just 5 minutes thanks to mega-fast charging speeds. It's just too bad that, from the front, it kinda looks like a fish. Design focused on aerodynamics The overall design is certainly … polarizing. But there are still a lot of cool details worth calling out. The wheels have electronically controlled moving blades that can open and close to maximize range or cooling as needed. All told, the overall shape is slippery enough to give the GT XX a drag coefficient of just 0.19 — a staggering number in terms of aerodynamic design.
