Ford and Mercedes join Renault in French emissions investigation

The French government is investigating certain models from Ford, Mercedes-Benz, and Renault because they allegedly produce more nitrogen oxide than the country's pollution rules allow, according to Automotive News, citing a French newspaper. After VW's emissions scandal, French regulators began checking more vehicles for evidence of defeat devices and excessive real-world pollution. According to Automotive News, the Mercedes S350 allegedly showed inconsistent results across these tests, and a Ford C-Max had NOx levels five times over the limit. The Renault Captur crossover, Espace, and an unnamed utility vehicle also had results that were too high. The French testing for this investigation includes an on-road emissions check that's not part of the EU's normal evaluations, which some automakers claim is unfair. "Unofficial on-road testing has varying conditions and can produce significantly different results," a Ford of Europe spokesman told Automotive News. Renault representatives met with French officials on January 18 to explain the situation. The company later submitted a plan to recall 15,800 examples of the diesel Captur, and said it would offer a voluntary software upgrade for about 700,000 other vehicles, according to Automotive News. Representatives from Ford and Mercedes will meet with the government soon, too. Renault's stock price plunged last week after investors heard that French regulators searched three of the automaker's sites as part of the emissions investigation. The stockholders feared an environmental scandal like the one currently embroiling Volkswagen. There's one major difference – as of now, there's no evidence Renault equipped any of the polluting models with defeat devices. Related Video:

2016 German Grand Prix race recap: so-so racing, great questions

We can summarize the 2016 German Grand Prix in one sentence: Mercedes-AMG Petronas driver Lewis Hamilton started second on the grid, passed pole-sitter and teammate Nico Rosberg before the first corner, and dominate to the finish. In fact, Hamilton turned his engine power output down on Lap 3 and still took the checkered flag seven seconds ahead of Red Bull driver Daniel Ricciardo. Ricciardo's teammate Max Verstappen crossed the line another six seconds back. Rosberg fell to fourth at the first corner and couldn't find the pace to reel in the Red Bulls. His questionable pass on Verstappen didn't help when the stewards penalized Rosberg five seconds; the overtake reminded us of Rosberg's move on teammate Hamilton in Austria. That penalty turned into eight seconds when the Mercedes-AMG Petronas stopwatch didn't work in the pits. Ferrari pilots Sebastian Vettel and Kimi Raikkonen finished fifth and sixth. Those six drivers all started in the top six, too. Behind them, on Lap 28 of the 67-lap race the next four drivers were Valtteri Bottas in the Williams, Nico Hulkenberg in the Force India, and Jenson Button and Fernando Alonso in McLarens. Low fuel and old tires put the kibosh on Alonso's pace just four laps from the finish, allowing Force India's Sergio Perez to pass, rounding out the top ten. The issues up for debate during the four-week break are far more interesting than the weekend's race. As bad as Ferrari's day might have been – and we'll get to that – Rosberg probably took the biggest hit, losing the race before the first corner for the second weekend in a row and falling 19 points behind Hamilton. Rosberg won the first four races of the season, then the teammates tripped over one another in Spain. Hamilton's won six of the seven races since Spain, Rosberg's best result in that time is a second-place in Hungary. Hamilton turned his engine down on Lap 3 (!) because he's used his entire season's allotment of five turbochargers and five MGU-Ks. Those early-season gremlins now have him on edge of grid penalties. Unless Hamilton's momentum cools off in August, however, that reliability danger might be the only dent in his armor. Rosberg, who once led the Championship by 43 points, will surely drown in his thoughts – and maybe schnapps – over the summer break. Whatever the Italian word for "meditation" is, there'll be a lot of it at Ferrari during the F1 summer break.

Aston Martin's deal with Mercedes-AMG more than skin-deep

Aston Martin is working on a raft of new models. But it's not going it alone: it has a technical partnership with Mercedes-AMG, the details of which have only been revealed in bits and pieces. If these latest spy shots are anything to go by, however, the arrangement could run deeper than anyone initially let on. Spied undergoing testing at the Nurburgring, this prototype for the upcoming successor to the Aston Martin DB9 is widely expected to be called the DB11 (10 is being used by James Bond's new ride). From the outside it doesn't look different than the previous versions we've seen running around, but this time we can also peer into the cabin, and that's where things start to get interesting. Despite the best arm-waving efforts by the development engineers, our spy photographers managed to snap a couple of shots of the interior. And though it looks far from being ready for production, the components we see appear to have been lifted from the Mercedes S-Class Coupe – particularly the steering wheel, digital instrument cluster, and almost the entire center console. This speaks to a deeper collaboration between the British and German automakers. The 4.0-liter twin-turbo V8 from the Mercedes-AMG GT, C63, and G500 4x42 is already being adapted for use in the next generation of Astons. Related Video:
