Mercedes Concept IAA shows its mighty morphing aero aids

Modern supercars are utilizing more active aerodynamic elements that constantly adjust, to make them some of the fastest things on the road. The Mercedes-Benz Concept Intelligent Aerodynamic Automobile is using them too, but the know-how is applied here for ultimate efficiency rather than turning better lap times. In the standard design mode, the four-door luxury coupe looks like a CLS from the near future with styling that's mixed with a little of the F 015 concept. However at the press of a button or upon hitting about 50 miles per hour, the IAA transforms into aero mode to have an insanely low drag coefficent of just 0.19. To achieve the ultra-efficient shape, the rear of the concept stretches over 15 inches to guide air down the tail. Flaps in the bumpers also extend outward, and the wheels adjust to improve the flow around the sides. To trim things out underneath, a portion inside the front bumper moves, as well. Inside, passengers sit in organically shaped leather seats, but occupants have to look at a vast array of purple and blue LED accent lights. The big panoramic roof is a nice touch, though. It would be interesting to watch water tumble over this slippery shape when driving in the rain. To maximize efficiency, Mercedes powers the IAA with a plug-in hybrid that's hooked up to a gasoline engine. The result is 275 horsepower and an electronically limited top speed of 155 miles per hour. On the European testing cycle, the company figures the concept could cover 41 miles solely on electric power in aero mode. Showing the gains of the swoopy transformation, that figure falls to 38.5 miles in design mode.

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:

Ferrari seeks review of Canadian Grand Prix penalty decision

Ferrari has asked for a review of the stewards' decision that cost Sebastian Vettel victory in the Canadian Grand Prix, a team spokesperson said on Monday. Vettel finished first in the race in Montreal on June 9 but lost the win after a five-second time penalty for going off track and returning in what stewards deemed to be an unsafe fashion. Mercedes' Formula One championship leader Lewis Hamilton was declared the winner instead. Significant and relevant new evidence that was not available at the time is required for a team to submit a 'right of review' under article 14 of the governing FIA's International Sporting Code. The spokesperson said Ferrari, who last week dropped a planned protest against the penalty, had formally requested the review but gave no further details "due to the sensitivity of the matter." Stewards will now have sole discretion to determine whether such a significant and relevant new element existed, with their decision final. If the review is deemed admissible, a secondary hearing will be held. Mercedes has won all seven races so far this season, and the last nine in total, with Britain's five-time world champion Hamilton now 29 points clear of Finnish teammate Valtteri Bottas in the standings. Vettel, who was furious with a decision that caused an immediate controversy, is 62 points adrift of Hamilton. Formula One holds its eighth race of the 21 round season in the south of France this weekend at Le Castellet circuit, where the penalty is likely to remain a major talking point. The Williams team requested a right of review last season against a three-place grid penalty handed to Russian driver Sergey Sirotkin, arguing that significant and relevant new elements had emerged. Stewards unanimously rejected the move. Motorsports Ferrari Mercedes-Benz Racing Vehicles F1 Lewis Hamilton Sebastian Vettel
