Mercedes-Benz Transformer
The IAA concept is a sleek-looking four-door coupe that indicates more or less the design of the next-generation CLS. Even more importantly, it employs a great deal of active aerodynamics to make it run as efficiently as possible in any given situation, making the most of fuel and saving the owner money.
How Does it Work?
Active grille shutters have been used on cars for years now, and they boost efficiency to a degree. When the IAA hits about 50 mph, things on the concept begin to “transform” so that the air flows past it in the best way possible. There are active grille shutters, as well as flaps in the front bumper that move back and toward the sides, directing air to the wheels and wheel arches. The wheels themselves change, transitioning from having five spokes each to becoming flat discs, allowing the air to slide over them better.
There’s a louvre in the front bumper as well, and it slides back about 2.4 inches, directing air more efficiently over the car’s underbody, an area many forget when talking about aerodynamics. One of the most unbelievable transformations is a rear, 15” extension designed to trigger a boat tail effect. It cuts down on turbulence behind the vehicle, causing the air to hug it more.
Fuel Efficiency
When all of these different pieces transform, the Mercedes-Benz IAA’s coefficient of drag goes from 0.25 to an amazing 0.19. That presents a very real advantage that would help the automaker meet or exceed ever-tightening government fuel economy standards. For you as a consumer, it means a distant purchase could incorporate at least some or all of these innovations, which would mean you still will enjoy a powerful vehicle without suffering the unpleasant effects of inefficiency.
Powering the Mercedes-Benz IAA concept is a plug-in hybrid powertrain, which has a peak total system output of 279 horsepower. When in aerodynamic mode, the car can travel up to 41 miles on pure electricity. The top speed of 155 mph is limited electronically.
Digital Design
Even more relevant to modern vehicles is the design of the IAA’s interior, affecting Mercedes-Benz models in only a few short years. In fact, the automaker says a “business” sedan will incorporate elements of the concept’s cabin very soon, which likely will be the next-generation E-Class. The head unit is completely digital, featuring two screens that measure 12.3 inches and sit side-by-side. Real-time graphics are displayed in crisp clarity, bringing to life the kinds of technology that only existed in big-budget movies. The touchscreen is supposed to have a surface that provides fewer distractions for drivers because it’s more user friendly.
The team took a mere ten months to develop the IAA, thanks to Mercedes-Benz using an entirely digital process. Normally, the development process takes about 18 months. According to the automaker, the new approach not only makes it quicker and easier to develop vehicles, it also increases the quality of the final product and should help introduce more diversity into the company’s model lineup
