Mercedes-AMG GT3 opts for big displacement without a turbo

There was a time when there were numerous categories in sports car racing: GT1, GT2 , GT3... but these days they've all been amalgamated into the latter. That's left a GT3 class packed with competitors and possibly more contentious than ever before. What you see here is Mercedes' new challenger, in official form after being leaked earlier today by the French website Le Point. Replacing the SLS AMG GT3 that won its class (among other races) the Nurburgring 24 Hours in 2013 is the new Mercedes-AMG GT3. Set to be revealed at the Geneva Motor Show, it's the racing version of the new Mercedes-AMG GT, and aside from looking the business, it has the makings of a highly competitive entry. As you can see, it sits closer to the track surface than the road-going version, and packs more extreme aero – including a front splitter you could serve dinner off of, little winglets to deflect the air away from the front tires, deep side sills, a massive rear wing and (though we can't see it presently) what promises to be a very large rear diffuser. It's also got more ventilation to feed the engine and cool the brakes, and a stripped-out cabin with full roll cage and a steering device that's long since evolved beyond resembling an actual "wheel." To save weight, Mercedes has redone many of the panels out of carbon fiber, but one of the most intriguing elements is what you'd find under that woven hood: instead of adapting the 4.0-liter twin-turbo V8 from the road-going GT, AMG has slotted in the larger atmospheric 6.3-liter V8 from the outgoing racer – coupled to a six-speed sequential gearbox. With its new GT3 entry, Mercedes surely hopes to take a slice of the customer racing market that Porsche in particular has developed into a successful and profitable business over the years. Racing fans, however, will be more interested to see how this puppy fares at Le Mans, the Nurburgring, the Blancpain sprint and endurance series, the United SportsCar Championship, the FIA World Endurance Championship and countless national series around the world. It'll have tough competition on its hands, though, from the likes of the Porsche 911 RSR, Audi R8 LMS, Bentley Continental GT3, Ferrari 458 Italia GT3, McLaren 650S GT3, Lamborghini Huracan GT3 and countless others that battle for glory on a racetrack somewhere on any given Sunday. World premiere in Geneva for spectacular AMG racing car All-out attack : the new Mercedes-AMG GT3 Affalterbach.

Mansory G63 AMG Sahara Edition substitutes performance for taste

We aren't sure if it's an unwritten rule or not, but it seems like European tuners are wholly incapable of building cars whose aesthetics don't offend people blessed with the gift of sight. Take Mansory, for example. The Swiss tuner has turned its hand to the Mercedes-Benz G-Class, a vehicle that on it's own is not exactly a visual stunner. Functional sure, but not exactly beautiful. But with Mansory wielding the design pen, the result is, well, yeah. It's not great. This is the Mansory G63 AMG Sahara Edition, and surprisingly, its camouflaged paint scheme is one of its least obnoxious qualities. But its grille, headlights, hood scoop, roof-mounted lights and rear spoiler just don't do this Mercedes any favors. And for some reason, the tuning firm has decided to put two different styles of 22-inch alloys. The driver's side isn't horrible, although we can't say the same about passenger-side hoops. The interior treatment is nothing compared to the cabin, though. Falcons. There are falcons in the headrests. No, we don't know why either. The avian theme isn't limited to the headrests, though, as Mansory has added wings to the seats, dash and door panels, all the while continuing on with camouflage color scheme on certain interior surfaces. Of course, if you can live with the design decisions, you'll be getting a ludicrously potent G-Wagen. Mansory has boosted the 5.5-liter, biturbocharged V8 to 828 horsepower while it's actually been limited to 737 pound-feet of torque. We aren't sure what the addition of 292 hp and 177 lb-ft of torque does to the G63's run to 60, although we're betting the Mansory version is a lot quick than the 5.3-second stock time.

Aston Martin reboots its EV offensive with Mercedes-Benz technology

Mercedes-Benz will provide Aston Martin the technology it needs to enter the electric car segment, according to the British firm's top executive. Its first battery-powered model is scheduled to arrive in 2025 at the earliest. As we've previously reported, Mercedes will increase its stake in Aston Martin to 20% by 2023. In exchange, it will grant the company access to its hybrid and electric powertrains. It's a win-win situation: On one hand, Mercedes can leverage the benefits of economies of scale. On the other hand, Aston Martin (which is far smaller) is able to access turn-key technology without spending an exorbitant amount of money on development. Executives are consequently rebooting Aston Martin's on-again, off-again electrification offensive. Its first electric model will be built using Mercedes-Benz-sourced technology when it goes on sale in 2025 or 2026, according to Automotive News Europe. Company boss Tobias Moers (who ran Mercedes-AMG until earlier in 2020) clarified the platform will come from Germany, but there's no word yet on whether the motor and the battery will, too. However, he confirmed plans to resurrect the Lagonda name on an electric-only sub-brand have been canceled. "Lagonda has a different purpose for the future. Electric-driven cars are supposed to be Aston Martins," he said. Hybrids are in the pipeline, too, including a gasoline-electric version of the high-riding DBX. Engineers were previously developing the technology in-house, but the project could end up in the automotive ash heap now that more Mercedes powertrains are in the picture. Moers affirmed he hasn't decided which route to take yet. "We are still working on that [hybrid drivetrain], but now we have alternatives. It's too early to say," he noted. Aston Martin will release the mid-engined Valhalla in 2021, and the plug-in hybrid DBX will begin rolling off the production line in 2023. Several new models will make their debut that year, Moers promised a "product firework," and it's reasonable to assume most will be available with some degree of electrification. He predicted every fourth or fifth car Aston Martin sells in 2024 will be electrified in one way or another. Green blues Aston Martin's path to electrification hasn't been smooth. In 2015, it joined forces with China-based LeEco to build an electric variant of the Rapide, but it was forced to finish the project on its own after its partner canceled the deal due to financial issues.
