- Among the many many aero-enhancing options of the AMG GT XX idea are energetic aero wheels.
- They open and shut relying on driving circumstances, and we may even see them in manufacturing.
- They do not have cables to speak to the automobile, 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 automobile’s drag coefficient.
It is a key difficulty for the GT XX, which might 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 mainly lived there, which is why Mercedes was in a position to obtain a coefficient of drag of simply 0.198. That’s even slipperier than the super-streamlined Volkswagen XL1, probably the most aerodynamic manufacturing automobile ever.
At 186 mph (300 km/h), round 83% of this automobile’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, over and beneath the automobile 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 automobile needs to maintain these louvers closed as a lot as attainable to protect its outstanding aero effectivity. Naturally, it has a very flat underbody—not having one at this degree is mainly malpractice—working with a rear diffuser to create a Venturi impact that helps hold the automobile caught to the street at excessive speeds. Even the aspect skirts are designed to direct the air in a calculated means.

However whereas all of that is cool and every part contributes to the GT XX’s outstanding aero credentials, it isn’t something we haven’t seen earlier than. In reality, there are manufacturing automobiles 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 automobile 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 automobile by any type 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 should 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 clarify that this concept originated as one engineer’s ardour venture that he labored on individually in his personal time after which delivered to the eye of administration. All people cherished the thought, particularly the truth that it had by no means been performed.
There’s only one little snag: determining tips on how to shield the Bluetooth wheels after they’re open when you’re making an attempt to parallel park subsequent to a curb. However, then once more, if Mercedes is definitely doing this for manufacturing, discovering a technique to forestall curb rash isn’t going to be the boss struggle. 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 value) could be justified.
