Rebirth 2004: I can make money by writing.

Monday, October 12.

Sunlight shines through the large windows of the spacious and bright conference room, casting a soft halo over the entire space.

In the large office of Future Automobile Company, the most elite R&D team of the automobile company is gathered - from core designers to process experts, from senior engineers to middle and senior management personnel, everyone is on high alert.

As the chairman, Hao Qiang rarely appears in the automobile company. His appearance itself means that an extremely important strategic decision is about to be announced.

Everyone present knew that this was no ordinary, routine meeting.

The company's large SUV, the ES8, will soon be launched on the market. It is a high-end six- or seven-seater model with a body length of 5.3 meters.

The standard 100-kWh lithium battery has a range of up to 580 kilometers and is priced at 88 yuan.

The high-end version is equipped with a 130-degree battery and is priced at 98 yuan.

The target market of this car is the luxury car consumer group with a budget of one million to two million yuan.

However, Hao Qiang's arrival today was obviously not to discuss the launch of ES8.

Hao Qiang rarely interferes in the affairs of the automobile company. He is responsible for the design of ET3, ES6 and ES7. The subsequent ES8 design is handled by the design team. The current MPV ES9 is also under the charge of the design team. He only gives the final review and approves it if he thinks there is no problem.

The automobile company's three current mass-produced cars are all designed by Hao Qiang himself and are selling very well. However, the ES8 is about to be launched on the market because the chairman is not involved in its design. The design team is a little worried.

The fact that Hao Qiang is an expert in automobile design has been verified by the market, and all R&D personnel in the automobile company admire the chairman's design ability very much.

At this time, Hao Qiang was sitting in a seat in the conference room, taking a sip of tea and slowly opening his laptop.

On the huge screen, a three-dimensional image of a futuristic car appeared.

The exterior design is more avant-garde and cool than the previous ET3, slightly similar to the design style of the rice SU7, but the body size is wider - the width reaches 2030 mm, the length is 5050 mm, and the height is about 1450 mm.

"This looks a bit like the ET0 concept car, right?" a designer couldn't help but ask, with a hint of confusion in his eyes.

"It looks very similar. Does the chairman want to mass-produce it?" another designer asked.

Hao Qiang looked around the room and heard the employees talking. The corners of his mouth curled up slightly, revealing a mysterious smile: "The main purpose of calling everyone to the meeting today is to talk about this car and assign research and development tasks.

Ladies and gentlemen, this is not the ET0 concept car, but the EF1!

A groundbreaking car, a flying car!"

Before he finished speaking, the entire conference room was in an uproar.

Flying cars?!

How could this possibly fly?

No one even saw the flying wings!

No external propellers were seen either.

Whispers rose and fell, and everyone's face was filled with disbelief.

Hao Qiang clicked the mouse again, and the design data of EF1 appeared on the screen:

【Main design features:

...]

Hao Qiang started by talking about the power system. The company is already able to mass-produce super lithium batteries, but has been stuck in not launching them on the market. It is planned to officially launch them in 2013.

High energy density means that the weight of the battery pack is greatly reduced.

According to the work done for a ground endurance of 580 kilometers (W=Fs=MgL), theoretically, the flying distance L in the air is less than one-tenth of the ground distance, and in reality it may only be able to travel 30 to 40 kilometers.

Unless, you replace it with a lithium metal battery and get a few hundred kilowatt-hours of power.

So, what is the practical significance of such a flying car?

This is also the common question of countless people at the scene.

Indeed, from a purely flight performance perspective, the vehicle's flight range is quite limited due to current battery technology.

Such a short flight distance may seem a bit useless at first glance.

What's more, under the current domestic airspace control policy, the use of flying cars is bound to face many restrictions and challenges.

In fact, Hao Qiang’s original intention in designing EF1 was not to create a pure aircraft.

If it's just flying, there's no need for ground flight, and the weight is lighter.

Its core value lies in breaking through the terrain limitations of traditional cars.

Hao Qiang opened the next slide and demonstrated several specific application scenarios:

Imagine that when a vehicle is stuck in mud or a deep pit, the ability to fly briefly can easily get out of trouble;

When off-roading in the wild, you can directly cross the dangerous terrain;

When facing the danger of falling from a high altitude, the flight system can automatically open and land safely;

When the highway is congested, some sections can be flexibly avoided;

Even crossing rivers and streams can be handled calmly.

More importantly, Hao Qiang continued, EF1 is also very useful in daily driving.

Through the coordinated work of the flight system and intelligent suspension, it can maintain extraordinary stability even on bumpy roads.

Imagine that when you accidentally drive into a deep pothole, a traditional car may cause chassis scratches, but the EF1 can easily and smoothly cross it.

If an emergency brake is encountered, the flight system can also assist in braking. It may take less than 20 meters to go from a speed of 100 kilometers per hour to a standstill, and there will be no problem of loss of control during emergency braking.

Therefore, Hao Qiang emphasized that the EF1's flight capability is more like a powerful auxiliary system rather than an aircraft in the traditional sense.

Our goal is to provide practical solutions in specific scenarios.

Of course, he added: "If in the future we have more advanced energy technology and can theoretically fly hundreds of kilometers, then we will build a pure flying car."

After Hao Qiang finished speaking, applause broke out in the conference room.

The attendees finally understood that EF1 was not just a gimmick, but a real innovative breakthrough - it would completely change people's perception of car functions and create a new paradigm for car use.

The chairman’s design is so creative.

Even with airspace control, this flying car will have almost unlimited freedom in the vast wilderness.

There is no need to fly very high, two or three meters is enough.

This height is just right to easily cross various ground obstacles.

Imagine, whether it's dense jungles, rugged mountains, or muddy swamps, this car can handle it with ease.

A flying car like this can go anywhere.

Of course, functional design is ideal.

Instead of adopting a traditional wing design, it innovatively uses a honeycomb structure air outlet system, which requires extremely precise intelligent control.

In other words, there are many carefully designed air outlets on the car body.

Is this wind force sufficient?

You should know that the wind force during a typhoon can easily overturn a vehicle weighing nearly two tons, while the EF1 weighs only 1.3 tons.

Therefore, as long as the lift provided by the propeller is large enough, lift will not be a problem.

Hao Qiang opened the next slide, and the specific position of the propeller was revealed.

Everyone's attention is focused on the front of the car - the location of the traditional fuel vehicle engine.

Four electric motors are prominently mounted on it, each driving a precision-engineered propeller.

The battery pack is cleverly placed at the bottom of the vehicle chassis, which not only ensures a stable center of gravity but also optimizes the aerodynamic performance of the vehicle.

After Hao Qiang explained these details, the participants were already impressed by this innovative design.

But what follows is another practical and acute problem – price.

How much will such a flying car that integrates intelligence and technology sell for?

Price is often the key factor in determining the market prospects of an innovative product.
