Regulators consider adding more carmakers to Takata recall

Volkswagen's diesel emissions scandal has been getting a lot of press recently, but the Takata airbag inflator affair could be grabbing headlines again soon. According to Bloomberg, the National Highway Traffic Safety Administration is contemplating an expansion to the campaign that could add seven automakers to the 12 already affected. They are Jaguar Land Rover, Mercedes-Benz, Spartan Motors, Suzuki, Tesla, Volvo Trucks, and VW Group. To be clear, there's no recall for any of these automakers, yet. The government is simply asking for a full list of vehicles that each of them have with Takata-supplied inflators containing ammonium nitrate propellant. The agency is concerned this substance could play a roll in the ruptures. "NHTSA is considering not only whether to issue an administrative order that would coordinate the remedy programs associated with the current Takata recalls, but also whether such an order should include expansion of the current recalls," the letters say. All seven can be viewed, here. From a report supplied by Takata, the government already knows that the company supplied 887,055 inflators with ammonium-nitrate propellant to VW and 184,926 of them to Tesla. In an incident during the summer, a side airbag allegedly burst in a 2015 VW Tiguan. In early September, NHTSA put out a revised report that there were 23.4 million inflators to be replaced in 19.2 million vehicles in the US. An earlier accounting from the agency had about 34 million of the parts in 30 million cars. High humidity is still believed to be among the biggest risk factors for the ruptures. Although, if ammonium nitrate also gets the blame, some already recalled models might need to be repaired again. Related Video:

Mercedes spotted testing hardcore AMG GT at the 'Ring

Mercedes has showcased its new AMG GT in both base and S trims, it's rolled out the GT3 racing version and the Formula One safety car. But we're only beginning to see the extent of the variants that the German automaker is expected to spin off of its new sportscar. And here is the latest. Spied undergoing testing at the Nurburgring is what appears to be an even more performance-focused version of the Mercedes-AMG GT. It seems to be packing an upgraded aero kit – complete with front splitter and rear wing – as well as larger rolling stock. You can bet there's an even more potent version underhood of the 4.0-liter twin-turbo V8 that's already producing over 500 hp in the existing model. Whether Affalterbach deems it worthy of the Black Series label or not is another question, but what's clear is that AMG is gunning for the Porsche 911 GT3 with the performance model you see here – however disguised it may be from our prying eyes.

Rain prolongs the Championship battle | 2016 Brazilian Grand Prix recap

Rain and an old-school circuit are the antidotes to Formula 1's constricting technical regulations and Tilke tracks. At Brazil's Autodromo Jose Carlos Pace – otherwise known as Interlagos – rain Saturday night and on race day washed away everyone's careful plans, except for those of the man at the front of the pack. Lewis Hamilton put his Mercedes-AMG Petronas ahead of the field throughout the weekend. On Sunday, a storm-delayed start behind the Safety Car assured Hamilton of a clean path to the lead and a clear track. The Briton didn't waste it, pulling out a gap on teammate Nico Rosberg behind, and Rosberg appeared to have no interest in going hard after Hamilton. Safety Cars and red flags kept resetting the gap to zero, though. After the Mercedes-AMG GT S led the first seven laps, it emerged again on Lap 13 for another six laps when Marcus Ericsson crashed his Sauber. Seconds after racing resumed, Kimi Raikkonen aquaplaned his Ferrari into the wall on the front straight. That caused the first red flag, leading to another eight-lap Safety Car interval, then a second red flag stoppage due to conditions on Lap 28, then three more Safety Car laps, and then, finally, racing again. Hamilton never surrendered his lead. The Briton changed tires once during a stoppage, and drove fast enough to cover the full race distance despite the intermissions. Afterward, he said "it was a very easy race." Rosberg had it harder, defending against the preternatural Max Verstappen in third. Barring misfortune it's already clear the Red Bull pilot has at least one Driver's Championship in his career future. In Brazil the young Dutchman drove like he's worthy of the hardware right now. After Verstappen passed Rosberg for second on Lap 34, the Red Bull driver pitted for intermediate tires on Lap 44 – a huge gamble in the conditions – coming back out in fifth. That tire wager failed, giving Rosberg a safe position in second when Verstappen had to pit for extreme wets on Lap 54 of 71. The teenager re-emerged in 16th. Over the race's final 17 laps Verstappen passed 13 drivers at six different places on track. He ran it close-but-clean a couple of times, especially when getting around Sebastian Vettel and Sergio Perez, but he was simply untouchable. Not only did the Dutchman score an amazing third place, he put in what could be the drive of the season.
