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.

Mercedes-AMG planning more hardcore A45 hot hatch

The launch of the A45 AMG marked Mercedes-Benz's first real assault on the premium hot hatch segment. And with 355 horsepower from a 2.0-liter turbo four, it is indeed hot. But the latest word has it that Mercedes-AMG is planning an even hotter version. Speaking with Auto Express at the LA Auto Show last week, AMG boss Tobias Moers indicated that his department was toying with the idea of a more hardcore version of the A45. In what Moers referred to as a "street fighter," the A45's engine would be tuned to produce even more power, the cabin stripped out and the rolling stock, brakes and aero upgraded for more serious performance. Think of it, then, as something of a Black Series approach, only it's not expected to carry that name, which has historically been reserved specifically for two-door models. Given AMG's current list of priorities and limited manpower, though, Moers suggests it will be several years – likely towards the end of the model's life cycle – before it may prepare such a model, following a similar formula to the Mini JCW GP and Renaultsport Megane R26.R. Here's hoping an American version based on the CLA could also be in the cards.

'The best Lewis' Hamilton faces resurgent Ferrari in F1

SHANGHAI (Reuters) - Lewis Hamilton has raised his game but whether the Mercedes driver can deny Ferrari a second successive win of the season in China this weekend remains to be seen. On paper, the triple world champion is still the man to beat -- the most successful driver by far in Shanghai with four wins to date. "Lewis is the best Lewis that I've seen in the last four years, both on and off the track," said Mercedes team boss Toto Wolff after the Briton started on pole and finished second to Ferrari's Sebastian Vettel in the Australian season-opener. "He has become a pillar of this team and he proved that in Melbourne." But Vettel is leading the championship, the first time a non-Mercedes driver has done that since he took his fourth title with Red Bull in 2013, and once-dominant Mercedes have a fight on their hands. Mercedes, who have taken both the drivers and constructors' titles for the last three years, have won four of the last five races in China. As Melbourne showed, however, past form may count for little in a season of sweeping rule change. "If you think you are going to cruise to victory in the future, based on a track record of success, you'll be proven wrong very quickly," said Wolff. "Australia was a weekend full of lessons, now we go to China ready and excited for another battle." Ferrari have not started a season with consecutive wins since 2004 at the peak of the Michael Schumacher era, the Italian team taking 15 victories from 18 races that season. Vettel's win in Australia ended a victory drought for Ferrari stretching back to September 2015, and drew rare praise from company chairman Sergio Marchionne, but they must now prove they can be genuine contenders. "You really have to go step by step," said Vettel. "It's good to know that we have a great car but it's just the beginning: new regulations, new generations of cars so there will be a lot of progress." The cars this year are longer and wider, sporting fatter tires and more swept-back bodywork as part of a rules shake-up aimed at making them faster, more spectacular to watch and harder to drive. But overtaking has also become more difficult, with Australia raising concern about the lack of real moves. The long straights and wide sweeps of the Shanghai circuit saw 128 passes last year, more than at any other track, and should provide a more definitive verdict.
