Cybertruck's Secret Hypercar Aero

The Tesla Cybertruck is strange and for many reasons but mainly the design, it looks rugged and a bit retro but it certainly doesn't look

dynamic but interestingly it is 60 less drag than a normal truck and in fact more slippery in a straight line than a bugatti chiron, something that is designed for maximum speed and this low air resistance is the reason it can outperform most supercars at 60 miles per hour and go over 500 miles on a single charge, as well What

dynamic magic has Tesla used to make this truck? It's so surprisingly slippery that it all starts with this strange, angular stainless steel body that day and night is different from the smooth rounded shapes of normal trucks.

Most pickup trucks use body-on-frame construction where the body mounts to a separate rigid frame that supports the engine. transmission and suspension, and this system is typically used on trucks as it has very high torsional rigidity, meaning you can ride it on two wheels off-road without the chassis twisting; However, the combination of a robust steel frame attached to a separate body is very heavy, which affects performance and handling and affects fuel economy, as a result, most cars today have a unibody design where the body itself is an integral part of the chassis, as the body is designed to be the central load-bearing structure of the car, this solution is much lighter than using a body with a separate heavy steel frame and the cyber truck uses a monocoque for this very reason: lightness while offering more space, and this decision is due to a challenge that normal trucks simply do not face: where exactly to place the Batteries.

A chassis-on-frame design would result in the chassis structure Steel takes up the space where the batteries need to be low on the floor, so the unibody design means the batteries can fit on the floor while the entire body supports the load rather than just the frame. This also allows Tesla to use similar systems to protect the batteries they use in their other cars. It is made up of a very strong aluminum structure that can withstand enormous impacts while maintaining its shape and this is important as things would go wrong very quickly if you were on an off-road vehicle and a rock pierced a battery and that would certainly ruin your fishing trip.

The cyber truck's monocoque is unlike anything we've seen before. It is made of an incredibly strong stainless steel alloy specially developed by Spacex for one of its rockets. Steel is so strong that it can stop bullets from a gun and the blow of a baseball bat. However, this has one major drawback compared to the softer steel or aluminum typically used to create car body panels: it is so strong that it cannot be pressed into shape like typical steel or aluminum, in its Instead Tesla could cut slots in the steel so that the sheets can be bent to form the shape of the body panels and this process explains the cyber truck's origami shape while also explaining why it doesn't have the complex curves it claims. which the f-150 has, but what's incredible is that Tesla has managed to make this body shape more aerodynamically efficient than the smoother shape of a typical pickup truck, so how the hell have they done this for In a car Normal road we don't care about downforce to increase cornering ability, so designers focus on reducing drag and of course this comes with a mountain of benefits, such as improving fuel economy or electric range, while improving straight line speed and reducing wind noise.

Cars tend to suffer from this as they seek to produce some downforce at speed, but while downforce is unnecessary for all but high performance cars, normal cars have to consider it to some extent and this is due to because most cars actually produce lift at high speed. Yes, the shape of the car can start to act like an airplane wing and even if you don't take off at highway speeds it can make the car feel unstable, so cars need to have some element of downforce to reduce this. effect. is a good example of this and is actually complex enough to have its own video, but long story short, Audi had to add a rear wing to prevent it from producing too much lift and becoming unstable at speed.

The cyber truck's clever design allows it to reduce both drag and lift more effectively than any truck on sale to get a little more technical. The main source of aerodynamic drag, especially in pickup trucks, is airflow separation for minimum drag. A car should aim for laminar airflow around the entire body. Look at a McLaren. speed queue to see how engineers try to keep air attached to the entire car to reduce drag. Laminar flow means that the air passing over the car travels in a smooth, regular path and causes minimal interference and friction with the body, in contrast, turbulent air flow is irregular. in its direction and speed, which creates more friction between the air molecules and the car body, when the smooth laminated air flow arrives at a severe angle, it cannot follow the shape of the car and flow along the surface , so the flow separates from the body and becomes turbulent in a normal truck this occurs mainly here and here and this is where most of the resistance occurs and it is for this reason that a racing car like the Low-drag Jaguar E Type has a much smoother roofline with no sharp angles. compared to a normal hardtop e-type, so the straight lines on the cyber truck would actually create a lot of drag, however tesla managed to avoid this, they managed to keep the roof angle low enough for the air to The completely flat, sloped design of the bed also gives the air less opportunity to separate from the body and become turbulent, but here's the really clever thing: Tesla has designed the front A-pillars to create vortices that are directed over the truck bed and push down. separate air and forces it to flow along the body, this design actually decreases the drag coefficient the faster you go as the airflow speed increases and these vortices become more effective at reducing air separation Not only this, the wake turbulence created at the back of the truck is pushed down and better controlled by the air flowing from the inclined platform and this effect is also greater at high speed, but the turbulence at the rear is also greater. it's intentional by design and part of the reason the cyber truck produces so little resistance.

The fascinating aerodynamic tricks of the Cyber ​​Truck is that the rear of the truck is designed to act as a virtual long tail at speed, so going back to the speed tail of the McLaren, this car uses this effect very well, all in the name of minimal resistance to achieve it. At higher top speeds, the shape encourages a really smooth airflow that doesn't split, keeping the pressure difference between the air at the front and rear of the car small. Now, this isn't something you can just bolt onto a truck. They needed access to the rear deck in addition to being able to step over things, so Tesla did something really clever with the airflow: they managed to create a speedtail cone shape, but with the air, they were able to maintain the practical shape of the truck while Al Minimizing drag at high speed, the smooth airflow along the cyber truck's inclined cargo compartment can continue in the same direction even after reaching the abrupt cut-off at the rear, as if the body were extending and continuing to narrow. down, but the arrow at the rear The front is just as impressive, where the cyber truck creates an artificial divider at speed to reduce lift.

The front of the truck has been designed to divert air to either side of the front wheels because turbulent air from the spinning wheels disrupts the airflow further down the car. and causes drag, however, while the nose may appear blunt and featureless, it has been designed so that an area of ​​low-speed, high-pressure air forms in the front of the truck at high speed, this high-pressure area pressure combines with low-pressure air flowing rapidly below. The truck has the effect of reducing lift by sucking the front of the truck down and the good thing is that this effect increases as speed increases so downforce is greatest when it is needed most but that is not all.

The cyber truck has an active self-leveling suspension. and the ride height can be changed to suit driving conditions for better ground clearance. The truck can be raised but can also be lowered to improve cornering ability. At its lowest setting, the Cyber ​​Truck minimizes the amount of air traveling under the body, which also has the effect of reducing lift and minimizing the drag of the truck and all of this work was so Tesla could create a truck that had the strongest possible chassis but without compromising the cyber truck could also be an ideal candidate for the next airless tires. that are in development, however, while they promise to perform similarly to pneumatic flanges, we believe they still have a long way to go.
