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.

Fastest cars in the world by top speed, 0-60 and quarter mile

A claim for the title of “Fastest Car in the World” might seem easy to settle. ItÂ’s actually anything but: Are we talking production cars, race cars or customized monsters? And what does “fastest” even mean? For years, car publications have tended to define “fastest” in terms of an unbeatable top speed. ThatÂ’s distinct from the “quickest” car in a Usain Bolt-style dash from the starting blocks, as with the familiar 0-60 mph metric. Professionals often focus on track lap times or elapsed time-to-distance, as with a drag racer thatÂ’s first to trip the beam of light at the end of a quarter-mile; or the 1,000-foot trip of nitromethane-powered NHRA Top Fuel and Funny Car dragsters. Something tells us, however, that you're not seeking out an answer of "Brittany Force rewriting the NHRA record books with a 3.659-second pass at a boggling 338.17 mph." For most barroom speed arguments, the focus is firmly on cars you can buy in showrooms, even if many are beyond the financial means of all but the wealthiest buyers and collectors. Here are some of the enduring sources of speed claims, counter-claims, tall tales and taunting dismissals that are the lifeblood of car enthusiasts – now with EVs adding an unexpected twist to these passionate pursuits.   Fastest from the blocks: 0-60 mph Thirty years ago, any car that could clock 60 mph in five seconds or less was considered extremely quick. Today, high-performance, gasoline-powered sedans and SUVs are routinely breaking below 4 seconds. As of today, the 2023 Dodge Challenger SRT Demon 170 crushes all with a 0-60 mph time of just 1.66 seconds. That's simply absurd, but keep in mind the Demon was engineered with the single-minded purpose of going fast in a straight line. It's also important to realize that direct comparisons are difficult, because not all of these times were accomplished with similar conditions (prepped surfaces, adjustments for elevation and so on). The moral here is to take these times with a tiny grain of salt. After the Dodge, the Rimac Nevera comes in with an officially recorded 0-60 mph time of just 1.74 seconds. EVs crowd the quickest list, with the Pininfarina Battista coming in a few hundredths slower (1.79 seconds) than the Nevera and the Lucid Air sapphire (1.89 seconds) right after that. Eventually, you arrive to the Tesla Model S Plaid, which has a claimed 1.99-second 0-60 mph time, though instrumented testing by Car and Driver shows it accomplishes the deed in 2.1 seconds.

Daimler ponders partnerships with Apple, Google

Daimler Chairman Dieter Zetsche is willing to consider joint ventures with tech giants like Apple and Google. Don't expect the automaker's vehicles to become just another platform for their software, though. In an interview with a German magazine, the chairman admits "different types" of partnerships could be possible, according to Reuters. As vehicles become increasingly connected, greater expertise is necessary in creating their software. The changing market is an opportunity for tech companies to enter the auto industry. "Google and Apple want to provide system software for cars and bring this entire ecosystem around Apple and Google into the vehicle," Zetsche said, according to Reuters. "That can be interesting for both sides." Although, he was clear no deals had happened, yet. For automakers, the danger of this cooperation is for a vehicle to be just a physical device that runs the software. "We don't want to become contractors who have no direct content with customers any more and supply hardware to third parties," he said in the interview. Zetsche has been working out how to create this balance for a while. Earlier this year, he said that some partnerships with Silicon Valley firms could be helpful. However, data privacy remains a major concern, especially in the wake of multiple vehicle hacks in recent months. In the chairman's opinion, a Mercedes-Benz shouldn't just protect its occupants physically but also their personal information. Related Video:
