The realm of electric vehicles has entered a bold new chapter, particularly evidenced by the highly anticipated launch of the Xiaomi SU7 Ultra track prototype on July 19. This vehicle, the product of an enterprising collaboration between tech giant Xiaomi and battery manufacturer CATL (Contemporary Amperex Technology Co., Limited), is making waves with its unparalleled performance attributesA striking feature of this cutting-edge vehicle is its employment of the second-generation Kirin battery, which is being showcased for the first time globally.

Providing robust high-performance battery capabilities, CATL’s technology enables an astonishing discharge power exceeding 1300 kilowattsIn terms of sheer strength, this vehicle boasts a peak power output of 1548 horsepower, allowing it to rocket from 0 to 100 kilometers per hour in a mere 1.97 seconds, with a top speed that surpasses 350 kilometers per hour

Such statistics don’t just impress; they set a benchmark for engineering excellence within the realm of electric cars, creating an environment ripe for the ultimate test of electric vehicle technology.

Describing the SU7 Ultra as an “ultimate test of electric vehicles” highlights the ambition behind its design—focusing on sustained high-speed energy output coupled with breathtaking accelerationAspiring electric vehicles are challenged by the necessity for so-called "sustained output"—not just an impressive launch but continued power under extreme conditionsThis involves a comprehensive evaluation of vehicle design, battery output capacity, thermal management, motor configuration, and braking control systems.

Historically, electric vehicles have fallen short in high-performance scenarios due to inherent technological limitations associated with battery and motor systems

For instance, once speeds exceed 200 kilometers per hour, motor RPM tends to plateau, while lithium battery systems often default into overheat protection mode when subjected to prolonged high current outputsThis factor has drawn criticism from enthusiasts, who often remark that while electric vehicles may start off powerfully, their performance trails off sharply.

Xiaomi took note of this feedback, and in response, the company unveiled the SU7 Ultra prototype as a means to rectify shortcomings perceived in previous models, particularly in balancing speed with style—a crucial demand from younger, style-conscious driversIn the SU7 Ultra, Xiaomi has assembled an arsenal of advanced technologies designed to bolster performance.

The SU7 Ultra is outfitted with a powerful tri-motor system, comprising two self-developed V8s motors and one V6s motor, culminating in an impressively combined peak power of 1548 horsepower

This configuration decisively addresses the traditional pitfalls associated with electric motors, particularly the rapid torque drop-off experienced at high speedsFurthermore, the vehicle’s design leverages the Kirin battery’s exceptional capabilities, with CATL stepping forward to deliver a track-grade battery package that enhances thermal management, controller systems, and battery performance.

Impressively, the high-performance battery provided by CATL supports a discharge power rating exceeding 1300 kilowattsThis modular pack enables the SU7 Ultra to accelerate from 0 to 100 kilometers per hour in just under two seconds, reaching 200 kilometers per hour in a swift 5.96 seconds—an unprecedented featCoupled with a braking performance that delivers a deceleration rate nearly 2.36 times that of gravity, it offers an exhilarating driving experience characterized not only by speed but also exceptional control.

Industry insiders comment that the partnership between Xiaomi and CATL signifies a remarkable evolution within the electric vehicle ecosystem

Traditionally, battery manufacturers focus on mass-market models, often taking a conservative approach regarding performance developmentsHowever, this new collaboration marks a pivotal departure from that norm, as CATL embraces the opportunity to exhibit its innovative battery capabilities—supporting Xiaomi in their pursuit of performance.

The Kirin battery technology pushes boundaries, enhancing existing high-nickel ternary battery performance while achieving a remarkable charging rate of 5.2CWith a maximum discharge power rating of 1330 kilowatts and peak voltage reaching 897 volts, the density scales up to 3,075 watts per kilogram—even under 20% battery capacity, the SU7 Ultra can still deliver over 800 kilowatts of power.

Innovations within the Kirin battery also extend to thermal management strategies, where cooling solutions are uniquely integrated into the design

For example, the horizontal and vertical beams alongside water cooling plates merge into a singular multifunctional layerThis intricate construction provides flexibility, allowing efficient temperature control and ensuring the reliability of the battery over its life cycle.

The introduction of large-area cooling technology within the battery module facilitates an instantaneous thermal response, with potential heat transference limited under extreme operating conditionsThese pioneering designs culminate in a vehicle that not only matches but surpasses traditional performance metrics seen in gasoline sports cars, unlocking a new wave of exceptionally capable electric vehicles.

With a concerted effort, CATL has founded joint ventures with multiple automotive manufacturers, fostering a new era of collaboration across the industry

This approach—where battery technology and vehicle design become deeply intertwined—is emerging as a powerful trend, signaling a transformative shift within automotive innovation.

The recent swiftness in development cycles showcases a dramatic evolution within China’s electric vehicle landscape, transforming what was once a lengthy process into a streamlined endeavorXiaomi’s commitment as they talk about their racing ambitions reflects their aim to catch up to competitors in a rapidly shifting marketIndeed, the SU7 Ultra prototype signifies a watershed moment, virtually erasing boundaries that once restricted the development of high-performance electric vehicles.

Xiaomi is poised to challenge itself at the Nürburgring in October, confidently declaring its commitment to racing and performance excellence
