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.

Recharge Wrap-up: Daimler spending big for fuel cells, Ford Go!Drive experiment advances

Ford's Go!Drive experiment is entering its beta phase in London. The project, which is one of the automaker's global smart mobility experiments, uses a mobile app for on-demand carsharing of Ford Focus Electric and Ford Fiesta vehicles. The beta phase involves increasing the number of available vehicles from 20 to 50, and collecting new data from users. The program offers one-way rentals and guaranteed parking, with no membership fees and a cost of 26 cents per minute. Ford hopes to get 2,000 drivers involved in the program.

The company expects cost savings "in the range of hundreds of millions of euros until 2020," while maintaining its workforce of 18,700 employees and adding 150 vocational training positions. The upgrades will allow the plant to become a center for building more efficient engines, hybrid powertrains and fuel cell systems. "Alternative drive systems are an important element of our future mobility," says Mercedes-Benz's Markus Schafer. "Their share of automotive production is set to steadily rise over the next few years, complementing our highly efficient engines within the portfolio. This is what we have laid the groundwork for today." Read more at Reuters, or in the press release below. The Department of Energy is providing $20 million in funding for the development of more efficient high speed industrial motors and drives. Ditching old motors and gearboxes for ones that use integrated power electronics could help decrease the energy consumption of the industrial sector, which currently uses more than 25 percent of the electricity generated in the US. The projects being funded will reduce losses and decrease the size of drive systems used in industries like petroleum refining and natural gas, which could affect the lifecycle efficiency of transportation fuels.

Editors' Picks April 2021 | Honda Accord, Mercedes-Benz E-Class and more

The month of April saw us award Editors' Picks status to a couple mega-luxury vehicles and a couple long-time standbys that recently went through mid-cycle refreshes. We drove plenty of other cars that didn't quite reach the bar for Editors' Picks status — BMW 4 Series, Infiniti QX55 and the Mitsubishi Outlander among others — but the four you'll see below stood out as the best this month. In case you missed our previous couple Editors' Picks posts, hereÂ’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in April that earned the honor of being an EditorsÂ’ Pick. 2021 Aston Martin DBX 2021 Aston Martin DBX View 16 Photos Quick take: With attractive styling and a gorgeous yet functional interior, the V8-powered DBX is a legitimate crossover worthy of the Aston badge. Score: 8 What it competes with: Bentley Bentayga, Lamborghini Urus, Rolls-Royce Cullinan, Mercedes-Maybach GLS 600 Pros: Mega style, fantastic driving dynamics, a true and faithful Aston Martin Cons: Very expensive, only average infotainment From the editors: Editor-in-Chief Greg Migliore — “The DBX captures the spirit of Aston Martin in a modern crossover. That's not an easy thing to do. I expected the DBX might look the part, but lack functionality. Or it would be a decent crossover, but fall short of my idea of an Aston. The DBX did neither. It exceeded my expectations and is an entertaining vehicle to drive. The styling is interesting and evocative, and the AMG-sourced powertrain delivers proper performance. I also loaded it up with groceries and a carseat fits pretty well. Mission accomplished for Aston." In-depth analysis: 2021 Aston Martin DBX First Drive Review | A crossover that makes you forget itÂ’s a crossover   2021 Bentley Flying Spur 2021 Bentley Flying Spur V8 View 20 Photos Quick take: There are technically competitors to the Flying Spur, but nothing matches it stride-for-stride in every category. ItÂ’s the Bentley flagship product now, and it flies the brandÂ’s flag with both gusto and excellence. You can't go wrong whether you spec the W12 or V8 either.
