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.

Formula One's Valtteri Bottas can turn it up to 11 in Spain

BARCELONA - Valtteri Bottas can add his name to one of Formula One's longest sequences by following up his breakthrough win in Russia with another triumph when the European season starts in Spain this weekend. The Finn, fresh from his first Grand Prix victory with champions Mercedes in Russia, is the man most likely to become the 11th different winner in a row at Barcelona's Circuit de Catalunya. No other track on the calendar has had such a variety of winners over the past decade, an ironic fact given that it is the most familiar to drivers from winter testing and was once famed for its predictability. Last year it was Dutch 18-year-old Max Verstappen who became the sport's youngest winner when he triumphed for Red Bull, on his team debut, after both Mercedes drivers collided at the start. In 2012, it was now-departed Venezuelan Pastor Maldonado -- a one-hit wonder -- who handed Williams a surprise victory that remains their most recent. Ferrari's championship leader Sebastian Vettel and Mercedes rival Lewis Hamilton, 13 points behind the German, will start as favorites and success for either could be an omen given that both went on to take the title last time they won in Spain. But Bottas, who joined Mercedes from Williams in January as replacement for retired 2016 world champion Nico Rosberg, is the best bet to continue the streak of different winners in Spain even if he has yet to finish higher than fourth there. "Getting that first win definitely gives me a lot of confidence that I can do it, even though I always knew I had the ability," he said after Sochi. "And now it's done, I just want to do it again and again." RICCIARDO REVIVAL The only other driver from the leading trio of teams yet to triumph in Barcelona is Verstappen's Australian team mate Daniel Ricciardo, but the Red Bull has lagged Mercedes and Ferrari on pace so far this year. That will surely change, with the flow of upgrades set to speed up now that teams are closer to their factories, and Red Bull have some big chassis modifications in the pipeline with engine improvements still to come. "I hope the upgrade will give us a chance to really fight with Mercedes and Ferrari or at least get us closer," said Ricciardo. The driver of car number 11, Force India's Mexican Sergio Perez, has racked up 14 successive points finishes and he too will have aerodynamic updates on his car.

2015 Brazilian Grand Prix is the same as it ever was

At this point, we hope Nico Rosberg is planning to carry his current qualifying form into the 2016 season and back it up with the same kind of race-day cojones he showed winning the race in Mexico City two weeks ago. The Mercedes-AMG Petronas driver got it right enough again on Saturday afternoon to take his fifth consecutive pole position ahead of teammate Lewis Hamilton by almost a tenth of a second. It's the same one-two from Brazil last year. The bad news for the rest of the field is that the winner in Brazil the last seven years has been one of the two drivers on the front row. Last year it was the Williams duo that lined up behind Mercedes, this year it's Ferrari. Sebastian Vettel plays the stalking horse, securing third in his Ferrari ahead of teammate Kimi Raikkonen in fourth. Williams driver Valtteri Bottas actually qualified in fourth, but he had to serve a three-spot grid penalty for passing under red flags in Free Practice 2, so he started sixth. That promoted Sahara Force India driver Nico Hulkenberg up to fifth. Daniil Kvyat was the quickest representative from Infiniti Red Bull Racing, getting into seventh even with a Renault power unit that's weak on some of the key stretches at the Interlagos track. Felipe Massa had the second Williams in eighth, in front of the second Red Bull driven by Daniel Ricciardo in ninth. Toro Rosso hasn't confirmed its drivers for next year but Max Verstappen keeps making it hard to look elsewhere, taking 10th. Rosberg is working nearly the same trick he pulled last year: drive like a second driver for most of the year, drive like a world champion for the last quarter of a season. He pulled away at the start and covered Hamilton just enough on the run to the first corner to keep Hamilton on the outside. By the end of Turn 1 the German had the lead and didn't give it up for the rest of the race outside of pit stops. Without overwhelming pace to pass and unable to follow closely, Hamilton could do nothing except ask his team for a different strategy to go for the win. When Mercedes told him "No," trying to protect Rosberg's second place in the championship ahead of Vettel, that was the race. Just like last year, Rosberg and Hamilton finished one-two. Vettel, Raikkonen, Bottas, Hulkenberg, and Kvyat drove lonely races to finish in positions three through seven.
