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.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

One year since accident, most of Schumacher's sponsors still on board

It's been almost exactly a year now since Michael Schumacher suffered massive head trauma in a catastrophic skiing accident in Switzerland, and while details on his recovery have remained few and far between, we're sure his progress has been anything but easy. Meanwhile his sponsors have faced a difficult decision of their own: to continue supporting him financially despite getting nothing tangible in return, or cancel their contracts and suffer the blow to their public image as a result. According to Schumacher's longtime manager Sabine Kehm in speaking to news outlets like Italy's La Gazzetta dello Sport, most of the imperiled former F1 driver's personal sponsors have remained by his side. The encouraging news updates on what we reported back in August, that Mercedes-Benz and German investment firm Deutsche Vermogensberatung AG were sticking with the champ through the hard times. Other sponsors, including helmet manufacturer Schuberth and watchmaker Audemars Piguet, are also believed to still be on board. Not all of Schumi's sponsors have stuck around, though. German bottled water brand Rosbacher reportedly broke off its contract with Schumacher back in July. And more recent reports confirm that Gaydoul Group fashion labels Navyboot and Jet Set canceled their sponsorship deal earlier this month. These and other contracts made Schumacher one of the world's highest paid sports figures and the first billionaire athlete in the world. Even in retirement, he was still making more than most active F1 drivers. While we don't know just how much he's pulling in during his recovery, here's hoping that his continued sponsors can find a way to make their support worthwhile – and that the champ makes a full recovery in the near future.
