- Among the many many aero-enhancing options of the AMG GT XX idea are energetic aero wheels.
- They open and shut relying on driving situations, and we might even see them in manufacturing.
- They do not have cables to speak to the automotive, and as an alternative use Bluetooth to know when to open and shut.
The Mercedes-AMG GT XX idea is brimming with cutting-edge EV tech that push the envelope by way of efficiency and charging. But it surely additionally has some fairly novel options, like its energetic aero wheels that open and near both permit for brake cooling or enhance the automotive’s drag coefficient.
It is a key situation for the GT XXwhich may go over 223 mph (360 km/h). At that pace, the air turns into your largest enemy. This idea didn’t simply go to the wind tunnel; it principally lived there, which is why Mercedes was capable of obtain a coefficient of drag of simply 0.198. That’s even slipperier than the super-streamlined Volkswagen XL1, probably the most aerodynamic manufacturing automotive ever.
At 186 mph (300 km/h), round 83% of this automotive’s oomph is used to beat air resistance. To handle this, the AMG can shift whether or not to make use of the air for cooling or let it cross by way of, over and underneath the automotive as effectively as attainable. It makes use of powered louvers within the entrance of the automobile which have a variety of movement, providing extra than simply open and closed positions.
The automotive needs to maintain these louvers closed as a lot as attainable to protect its exceptional aero effectivity. Naturally, it has a totally flat underbody—not having one at this degree is principally malpractice—working with a rear diffuser to create a Venturi impact that helps maintain the automotive caught to the highway at excessive speeds. Even the facet skirts are designed to direct the air in a calculated method.

However whereas all of that is cool and every little thing contributes to the GT XX’s exceptional aero credentialsit isn’t something we haven’t seen earlier than. Actually, there are manufacturing vehicles with extra superior and excessive energetic aero than this idea, however none have energetic aero components on the wheels. The research options flaps on the wheels that open and near both cool the brakes or make the automotive extra slippery.
They’re linked to a central hub that Mercedes says will get its energy from the rotation of the wheel and isn’t linked to the automotive by way of any form of cables. It as an alternative makes use of a Bluetooth connection, which is a really novel use of wi-fi connectivity. Bluetooth-enabled wheels are usually not one thing I ever anticipated to jot down about.
After I requested Mercedes-AMG CEO Michael Schiebe if these wheels would hit manufacturing, he smirked and mentioned that the probability was “not low.” Cue each journalist on the spherical desk beginning to giggle whereas placing this down of their notes.
Schiebe went on to elucidate that this concept originated as one engineer’s ardour undertaking that he labored on individually in his personal time after which dropped at the eye of administration. All people liked the concept, particularly the truth that it had by no means been achieved.
There’s only one little snag: determining the way to defend the Bluetooth wheels after they’re open when you’re attempting to parallel park subsequent to a curb. However, then once more, if Mercedes is definitely doing this for manufacturing, discovering a approach to forestall curb rash isn’t going to be the boss combat. The deciding issue will finally be whether or not these energetic wheels really present a profit for cooling and/or aero, and if the additional complication (and price) might be justified.
