That's right, pre-release. At the first press conference of Xiaomi Auto, it was originally a technology sharing, but Lei Jun was high-perhaps because of the recent intensification of market competition, and it was necessary to put the car on the market in advance, so that potential owners could keep hundreds of thousands in their pockets - Xiaomi Auto, which was officially unveiled.

And it's also unmanned, self-staged:

Of course, in today's world, the new car launch, who still drives is embarrassed.

But as Xiaomi's first car built in 1003 days with a high profile, this "muscle" is only one of the highlights.

One afternoon13 hot searches, not only the reason for Xiaomi's long-sleeved marketing, but also the highlight of Xiaomi's first car.

A friend who plans to buy a Porsche, a Tesla car, or anyone who has a budget of 300,000 and plans to change his car

Now, you can wait for the "time-keeping meter".

The official positioning of Xiaomi Su7:C-segment high-performance sedan

Xiaomi su7 design has been ** for a long time, and this time it was officially announced that the wind resistance:0.195cd, officially said to be the world's lowest wind resistance among the world's mass-produced cars.

There are 8 air ducts, 17 real air vents, and an electric rear wing that provides 130kg of downforce.

In addition to the low wind resistance, the Xiaomi Su7High performanceMore reflected in the fact that the dual-motor version has a maximum horsepower of 673 horsepower, a peak power of 495kW, and a peak torque of 838Nm.

In this way, it only takes to achieve 000 acceleration2.78s, 0-200km h time10.67s, officially declared"Performance surpasses the Taycan Turbo across the board".

Not only can you run, but you can also brake. The braking distance of 100km h-0 is:33.3m, which is also smaller than the Taycan Turbo.

At the same time, Xiaomi Su7 also supports "wireless degrees of freedom" custom driving mode, which can accurately adjust the power, steering, suspension, front and rear drive distribution ratio, etc., and can support up to 16800 million driving modes.

Also added extraboost modeWhen accelerating and overtaking, press the red button to immediately accelerate the vehicle, providing excess torque output that lasts for 20 seconds.

The chassis is a pure electric chassis developed in the forward direction, and it is equipped with various performance car configurations

And in addition to high performance, the second major feature of the Xiaomi Su7 trailer isLong battery life and ultra-fast charging

The Xiaomi SU7 dual-motor version is equipped with 101kWhBattery pack, CLTC endurance is800km*。

At the same time, it supports super fast charging, charging for 5min, and the range is 220km;It can be charged for 15 minutes and has a range of 510 km.

In addition, Lei Jun said that Xiaomi Su7 also achieves a higher low-temperature endurance retention rate, faster low-temperature charging speed, faster low-temperature air conditioning heating rate, and lower low-temperature power performance attenuation.

In addition to the above electrification-related performance, Xiaomi Su7 also detailed its capabilities in intelligence this time.

Let's start with thatIntelligent driving

Chips are familiar facesNvidia Orin-X, Xiaomi Su7 is equipped with two, with a total computing power of 508TOPS. There are also 27 sensors, including 1 lidar.

Under such a hardware configuration,XiaomiSU7Support intelligent driving with three domains,That is, on top of the basic L2,There are high-speed NOA、Urban NOA and valet parking。

In the actual test, Xiaomi Su7 can avoid large cars in the open section of the evening peak city, bypass vehicles occupying the road, turn left and right without protection, and give way to pedestrians15 kinds of operations, and the official said that the whole process 0 took over.

And whereasValet parkingIn terms of aspects, Xiaomi su7 can not only find a parking space by itself:

You can even park on the side with only 005m mechanical storage location:

In addition, there are more technologies, which Lei Jun said will elaborate in more detail at the official press conference.

Lei Jun said that by the end of 2024, Xiaomi will enter the first camp of the intelligent driving industry.

On the other hand, intelligence is:Smart cockpit, Lei Jun said that this is also the strongest part of Xiaomi.

The hardware is the most advanced at the momentQualcomm 8295Get in the carIt can be realized in the carFive-screen linkage**. These five screens include 161-inch central control screen, 71-inch reversible instrument screen:

56-inch HUD (Head-Up Display):

The other two are on the rear seatsExtended screenFor example, Xiaomi Pad can be directly accessed, and the "one-second car machine" realizes car control:

In addition, some physical buttons are also retained in the car, including:

Lei Jun introduced,The first feature of the Xiaomi Su7 complete set of car machines isThe interactive experience is good

The operation logic is similar to that of a mobile phone, and you can quickly get started without learning. For example, Xiaomi's characteristicsMulti-tasking flexible frameto resize the window:

It also supports mobile phone car machineNon-inductive connectionNavigation and other functions support cross-terminal circulation.

Another feature is:FastFast start-up1.49sExtremely fast start;Upgrades are also fast: Cockpit system upgrade only3 minutes, the whole car upgrade is only required30 minutes

At the same time, the Xiaomi Su7 also has a rich ...Software EcosystemwithHardware ecology

Tablet and mobile phone applications should be on the top, support the mobile phone application pin to the car, and change the native application of the car machine in seconds.

At the same time, there is support for a variety of kindsHardware expansion, Xiaomi calls this set of ecology cariot, such as the one mentioned aboveRear expansion screenIt is one of the expandable hardware, which can be connected and control air conditioning and seats.

Central control screenStorage tableIt also supports hardware expansion, such as adding a keyboard under the center console, or putting a car diffuser in the storage table.

Lei Jun said that as long as it is a Mijia device, it supports password-free connection with the account, and there is no sense to get on the car, and this ecosystem is also open to global ecological developers.

In addition, Xiaomi Su7 also fully supports CarPlay, AirPlay, and the rear expansion screen also supports the use of iPad.

Xiaomi's strong ecological capability is a well-known thing, and since this is an automotive technology conference, the above capabilities are naturally indispensable behind XiaomiSelf-developed automotive technology

This time, we mainly introduced five aspectsMotorsBatteryLarge die castingIntelligent drivingwithSmart cockpitLet's take a look at them one by one.

The first is Xiaomi's "super motor". The Xiaomi Su7 will be carriedSuper Motor v6withSuper Motor V6S

Among them, the super motor V6S has the highest speed21000rpm, officially said that it far exceeds the level of Tesla and Porsche's motors.

In addition, Lei Jun said that although a friend (Huawei) has released the highest speed motor, the maximum torque, maximum power and so on are still not comparable to the super motor V6S.

Xiaomi's motor is also one of the most leading and powerful motors in the industry.

And the super motor V8S has achieved mass production and will be in the futureIn 2025Get in the car

Lei Jun said that the speed increase of the motor must first solve the rotor strength, and Xiaomi's super motor uses ultra-high strengthSilicon steel, the yield strength is 960MPa.

At the same time, Xiaomi has also redesigned the stator and rotor, as well as the SiC electronic control module, with a conversion efficiency of 9985%。

At present, Xiaomi has applied for 155 patents in motors, 60 of which have been authorized.

In addition, Lei Jun also announced that Xiaomi has been pre-researching the next generation of super motors, using laser in-situ curing process to wind carbon fiber, and the rotor speed has been achieved in the laboratory35000rpm

Secondly, in terms of batteries, Xiaomi and CATL have cooperated to launch800V high voltage battery pack

The battery pack is self-developed by XiaomiCTB integrated battery technology(cell to body), the battery pack is integrated into the body to reduce the vertical height of the car and increase the passenger space.

In addition, this battery pack also supports capacity extension, supporting up to 150kWh capacity, and the battery life can be exceeded1200km

According to Lei Jun, this battery is characterized by high efficiencySecurity aspectsIt also has a good performance.

Xiaomi implements "the world's most stringent thermal failure safety standards" for the battery.

Officials said that when the battery is fully charged at 55°C, even if it does not rely on the water cooling system at all, it can ensure that no thermal propagation occurs.

In terms of heat insulation and heat dissipation capabilities, Xiaomi batteries have 17 layers of high-voltage insulation protection, 14 layers of hard-core physical protection, and a double-large cooling area (78m), the side of the cell is also filled with 165 pieces of aerogel insulation material, which can resist up to 1000 high temperatures.

The Xiaomi Su7 will also play a role in the vehicle-cloud collaborative safety warning system, which can detect more than 800 signals per secondThere are also full-stack self-developed onesBattery management softwareIn case of emergency, the current can be cut off within 4 milliseconds.

Not only that, but Xiaomi is also the first of its kindCell inversion technologyThe pressure relief valve is inverted to protect the safety of users in the car.

Xiaomi has applied for 132 patents in batteries, authorized 65, and also has its own factory.

In addition, in terms of battery thermal management, Xiaomi has also released two technologies.

One isXiaomi's high-efficiency dual-mode heat pump technology: -20 degrees Celsius, the heat pump still draws heat from the cold air;The other isXiaomi pioneered the three-heat source step-by-step energy gathering technologyIt can gradually gather the waste heat produced by the electric drive, the heat energy of the compressor and heater, and transfer it to the cockpit.

Lei Jun said that Xiaomi SU7 should be the "king of winter tram endurance".

The integrated die-casting rear floor of Xiaomi Su7 has achieved a breakthrough in both materials and die-casting equipment.

The first is custom-madeAll-in-one die-casting machine, maximum clamping force9100t, which is higher than Tesla's just-completed 9000t integrated die-casting machine.

At the same time, Xiaomi has also developed a large die-casting equipment cluster system, including an integrated die-casting machine, assembly production line, mold pouring system, etc., including 60 devices, which can accurately control 433 process parameters.

In addition, in terms of materials, Xiaomi has launched a combination of strength, toughness and stabilityXiaomi Titan

As a result, the integrated die-casting floor has 840 fewer welds, a 17% weight reduction and a service life of more than 2 million kilometers.

The algorithm of Xiaomi's intelligent driving system adopts BEV+Transformer + occupation network, integrates into the large model, and makes three technological innovations in perception at the same time.

One isZoom BEVtechnology that dynamically adjusts the sensing range.

This can make the parking recognition more accurate, with a minimum accuracy of 005m。

The urban scene can be seen wider, up to 160m:

The second isSuper-resolution occupancy network technology

Xiaomi has added a super-resolution vector algorithm to the occupied network, which directly simulates all visible objects seen on the road surface into three-dimensional objects with continuous curved surfaces, improving the recognition accuracy and precisionLess than 01m

The third isRoad model technologyIt can generate road topology in real time, and the official effect is comparable to that of a high-definition map, and it can also judge the road surface conditions in real time like a person. For example, if the road ahead is being repaired, it can also accurately generate intelligent guidance lines for smooth detours.

The support behind the ecology of software and hardware mainly comes from Xiaomi's self-developmentSurging os

Because this part of the conference is mainly to introduce various software and hardware expansions and operations, I will briefly mention the surging OS here.

Its architecture is as follows:

There are two key words,FusionwithEmbedded

On the one hand, Xiaomi Surging OS has integrated the on-board OS into the large embedded system base;On the other hand, this embedded system base is also a management system for the control of various hardware devices.

Specifically, you can refer to what we have interpreted before, so I won't repeat it here.

The above is the core information of the first press conference of Xiaomi Auto.

To sum up, after three years of building a car, Xiaomi finally handed over the volume:

In terms of appearance, it is competitive;

Technologically advanced, competitive;

In terms of product and user experience, it is competitive;

The only thing that hangs in the balance, only remainsPricing:, whether it is competitive.

At today's press conference, Lei Jun has clearly vetoed it90 thousand914.990,000**, which was revealed to the public clearly and secretly before, is basically heading towards the 300,000 file.

In fact, as a C-class sedan, the pure electric and intelligent technologies have been full, and it is also equipped with luxury car configurations such as air suspension, and almost all of them are rushing to 300,000.

But the reason why Xiaomi is Xiaomi, or why Xiaomi has become the Xiaomi that has attracted much attention today, is that it has met the expectations of the outside world again and again, detonated the needs of users, and "always believe that good things are about to happen".

So it may be true that as Lei Jun said, how much is the price of Xiaomi's first car, and I am still thinking about it, and there is no conclusion.

Perhaps in the end, it will also take into account factors such as cost, production capacity and high-end brand building, and will not choose "cost-effective" pricing.

This speculation will need to be confirmed at the listing conference in a few months, but it seems to have been "confirmed" at other levels.

Because today's Xiaomi car created 13 hot searches in the afternoon, but in the end, it almost did not bring changes in stock prices, and even fell slightly in the end.

This contrast is worth paying attention to. The reason behind the contrast is worth thinking about.

Slightly interestingly, after the name of Xiaomi Su7 was repeatedly mentioned by Lei Jun, Xiaomisu7seems to have become very certain:

are you ok？
