Honda to expand two-motor hybrid vehicle lineup

Xiaomi has recently “pre-launched” the Xiaomi SU7 electric car. This completes its venture into the EV scene. The company is moving further beyond producing just smartphones and AIoT devices.

On paper, the Xiaomi SU7 is positioned as a “full-size high-performance eco-technology sedan.” It aims to push the limits performance, ecosystem, and mobile smart space.

To ensure that this EV offering is indeed ready to redefine the automotive industry, Xiaomi has worked on five core technologies that serve as the foundation of the Xiaomi SU7, working on a “bottom-up” approach by consulting key sectors and investing over US$ 1.4 million (CN ¥ 10 million) to develop these cores.

The result is the highly-anticipated Xiaomi SU7 in its flesh. So far, here’s what we need to know about the upcoming EV from the Chinese consumer electronics giant.

E-motor

The Xiaomi SU7 boasts of three Independently-developed motors: the HyperEngine V6, HyperEngine V6s, and HyperEngine V8s.

These e-motors feature a bi-directional Full Oil Cooling Technology and an S-shaped oil circuit design for cooling and better heat dissipation.

In terms of performance, these motors help the vehicle achieve record-breaking numbers when it comes to e-motors, as measured in rpm, output, and peak torque.

Specifically, the HyperEngine V8s logged a maximum rotational speed of 27,200 rpm, 425kW output, and 635Nm peak torque.

The HyperEngine V8s is in development and set to be mass-produced and implemented in Xiaomi EVs by 2025.

Battery

The battery inside the Xiaomi SU7 likewise has a self-developed CTB Integrated Battery Technology through Inverted Cell Technology.

Xiaomi claims a 77.8% battery integration efficiency and 24.4% overall performance improvement with this battery, leading to a maximum capacity of 150 kWh and about 1,200-kilometer range on one full recharge.

To ensure stability throughout travel, a 14-layer robust physical protection system safety design and dual-side water cooling solution have been employed.

Xiaomi Die-Casting

Xiaomi SU7

For its die-casting, Xiaomi came up with the Xiaomi T9100 cluster and proprietary casting alloy material called Xiaomi Titans Metal.

This material is a high-strength, high-resilience, heat-treated die-casting material that was a product of Xiaomi’s research and development.

The application of the T9100 cluster allows the Xiaomi EV’s rear underbody to integrate 72 components into one, reducing welded joints by 840 and decreasing the overall car weight by 17%.

When the car gets mass produced, the innovation will reduce the production hours by 45%.

Xiaomi Pilot Autonomous Driving

Not to be outdone in intelligent software, Xiaomi will employ three key technologies for autonomous driving. These are:  Adaptive BEV Technology, Road-Mapping Foundational Model, and Super-Res Occupancy Network Technology.

The first technology focuses on perception algorithms based on scenarios. It is aided by an expanded recognition range for better visibility in urban, high-speed, and parking situations.

The Road-Mapping Foundational Model revolutionizes traditional methods of perceiving road conditions. This helps drivers recognize them in real-time to switch to a more reasonable driving trajectory. All the while navigating smoothly in complex intersections based on interaction and driver habits.

Lastly, the Super-Res Occupancy Network Technology achieves unlimited categories of recognition for irregular obstacles. Compared to traditional networks that interpret obstacles as blocks, the vector algorithm for this will simulate all visible objects as continuous curved surfaces. This improves the recognition accuracy to as low as 0.1m.

For parking, Xiaomi has also developed the world’s first End-to-End Sensing and Decision-Making AI model for automated parking that puts premium on real-time observation and dynamic adjustment when parking in difficult scenarios.

These software advancements are complemented by an equally-innovative set of hardware that consists of NVIDIA Orin high-performance chips, one LiDAR, 11 HD cameras, three millimeter-wave radars, and 12 ultrasonic radars.

Smart Cabin

To cap off the five cores, the Xiaomi EV Smart Cabin adopts a human-centric interaction architecture. That’s represented by its 16.1-inch 3K central console, a 56-inch HUD head-up display, 7.1-inch rotating dashboard, and two backseat extension mounts for two tablet devices.

This Smart Cabin system is equipped with an in-car Snapdragon 8295 chip. It has a computing power enough to link all five different screens. That should provide the ultimate interactive experience.
