Mercedes-Benz Concept IAA is a modern silver aero

While we English-speaking folk call it the Frankfurt Motor Show, our German friends call this week's bi-annual confab the Internationale Automobil-Ausstellung, or IAA. At first glance, then, you might think Mercedes-Benz named its Frankfurt concept, the Concept IAA, after the show it'd debut at. But, the Concept IAA isn't named for the show. It's actually an abbreviation for Intelligent Aerodynamic Automobile, and it's very aerodynamic indeed. This four-door coupe can transform, while moving, from its sedan-like design mode to an ultra-sleek, gas-powered fish of a car. This aerodynamic mode has a drag coefficent of just 0.19. That's sleeker than a Tesla Model S, and it ties the rating of the General Motors EV1 electric car. In fact, it's very nearly as aerodynamic as the Volkswagen XL1. The IAA can transform automatically at 80 kilometers per hour (about 50 miles per hour) or via the press of a button. When it enters an aerodynamic mode, eight segments at the back of the car extend out, adding over 15 inches to the overall vehicle length, effectively extending its already tear-dropped-shaped tail. And that's just the most visible aero aid. At the front of the car, flaps in the bumper extend out nearly an inch, while there's a smaller extender in the back bumper. These serve to keep air away from the wheel arches, where turbulence can become an issue. Of course, Mercedes has thought of this, too, fitting "Active Rims" that "alter their cupping from 55 mm to zero," whatever that means. There's even an active aero aid inside the front bumper, where a louver extends backward by 2.3 inches to smooth out the air traveling underneath the car. Outside of its super-slippery mode, the IAA is a relatively handsome four-door coupe, featuring the kind of plunging roofline that wouldn't look out of place on the company's pioneering CLS-Class. The interior is certainly worthy of the CLS, too. It's home to gorgeous white leather and touch-based controls, and in general, looks very luxurious. Mercedes' dogged pursuit of aerodynamics does not mean that the Concept IAA is some gutless ecomobile. Under the skin is a gas-powered, plug-in hybrid system that produces up to 279 horsepower and allows the sleek sedan to hit 155 mph. Its all-electric range is based, of course, on what mode its body is in. It's most impressive in aero mode, where it will cover 41 miles on a single charge. Switch over to design mode, and that figure drops slightly to 38.5 miles.

BMW can't build enough M3 wagons, but the U.S. won't see any

Why, oh why, won’t the automobile companies that supposedly cater to Americans give us a viable touring wagon? Seems that BMW is one manufacturer thatÂ’s aware of the question, but skirts the answer. WhatÂ’s more frustrating is that the German company, and others, have for years been off-handedly tossing out the same refrain: “Maybe weÂ’ll bring a wagon back to the U.S.” Not. All the more irritating then is the news that the Bavarians have increased production in Munich of its M3 Touring longroof version to keep up with demand. The information comes via Bimmer Today, which spoke with BMW M CEO Frank van Meel. He said that the company was surprised by the amount of interest in the M3 Touring since its debut during last year's Goodwood Festival of Speed. In fact, he said, the company had to facilitate a production ramp-up within its Munich facility. Despite that increased production, the backlog of orders means that customers are still on wait lists, he said. Last year, van Peel admitted that demand for M-wagons in the U.S. has been steadily increasing, and exporting a touring example was a concept BMW was "taking into consideration.” Crossovers certainly are this decadeÂ’s version of the wagon, which leaves American enthusiasts will few choices: only expensive versions from Audi, Volvo and Mercedes-Benz and a couple of others. Details that were announced last year — a few months before the wagon went into production for sale in Europe, the U.K. and elsewhere — noted that the M3 Touring was only available in Competition spec with xDrive all-wheel drive and a 3.0-liter twin-turbo inline-six with 503 horsepower and 479 pound-feet of torque. Pricing started at GBP80,550 ($105,000 U.S.) More data on the M3Â’s intro here. Related video:

Renault-Nissan rejig how they manage Daimler partnership, sources say

PARIS — The Renault-Nissan-Mitsubishi alliance is set to scrap a role overseeing ties with Daimler in favor of individual relations with the German group, three sources told Reuters, as they try to better manage a partnership that has not met initial hopes. The shift comes as alliance-level executive Jacques Verdonck, who was in charge of the cooperation with Daimler, retires at the end of the month, the sources familiar with the matter said. France's Renault will instead rely on its head of partnerships, Sandra Gomez, while Nissan will do the same with Catherine Perez. Mitsubishi will also have a person in charge of partnerships, the sources said, adding the bilateral approach was in line with the new "leader-follower" strategy of the alliance. That involves leaning on the strengths of each carmaker in certain areas. Renault and Daimler declined to comment, while Nissan could not immediately be reached for comment. The plan marks another shift following the end of the Carlos Ghosn era at the alliance. The architect of the Franco-Japanese partnership, who also extended the collaboration to Daimler, was arrested on financial misconduct charges in Japan in late 2018, before fleeing to Lebanon in 2019. He denies any wrongdoing. His exit strained already difficult relations between Nissan and Renault, which are now working to get back on track with cost-saving joint production projects among other steps. The partnership with Daimler - which owns high-end brand Mercedes-Benz, contrasting with the more accessible models produced by the others - has also looked in danger of losing steam. Nissan and Renault, both hit by losses, recently sold down their stakes in the German group. Collaborations on Renault's compact Twingo car and Daimler's Smart model are set to end, and some targets for industrial cooperation have been downgraded over the years. But Daimler still has a factory in Mexico with Nissan, and has been exploring the possibility of jointly developing at least one large van model with Renault. An industry shift towards electric vehicles could yet yield other opportunities, one of the sources said. "The collaboration with Daimler is at present made up of Renault-Daimler projects, Nissan-Daimler ones and some between the three," another of the sources said, with yet another saying that the changes reflected a more pragmatic approach.
