The Xiaomi-developed HyperEngine V8s has a maximum speed of 27,200 rpm, a maximum horsepower of 578, and a peak torque of 635 Nm, making it the most powerful motor produced by the Beijing-based company. Moreover, the Xiaomi SU7 Ultra is equipped with a CATL’s Qilin 2.0 high-power battery dedicated to racing, with a maximum output of 1330 kW. Even at 20% SoC, the battery can discharge 880 kW of power.
Interestingly, CATL’s Qilin batteries have iron phosphate (LFP) chemistry. SU7 Ultra will have 897V charging and support a 5.2C charge rate, meaning the car can be recharged in less than 12 minutes.
In terms of braking, it is equipped with AP Racing high-performance brake calipers specifically for racing, featuring six-piston forged fixed calipers at the front and rear, and racing brake pads capable of withstanding working temperatures of over 800 degrees.
Additionally, the Xiaomi SU7 Ultra uses motor reverse for brake energy recovery, providing a maximum of 0.6G braking force recovery. Under full braking conditions, it can provide a deceleration of more than 2.36G, with a 0-100 km/h braking distance of only 25 meters.
The SU7 Ultra can accelerate from 0 to 100 km/h in just 1.97 seconds and 0 to 200 km/h in just 5.97 seconds, reaching a top speed of 300 km/h in just 15 seconds. The maximum speed is reported to be 350 km/h and the vehicle weighs just under 1,900 kg.
The Xiaomi SU7 Ultra’s design is notably different from the standard SU7, featuring a massive carbon fiber rear wing to generate up to 2,145 kg of downforce. The rest of the car has also been modified for more aerodynamic structure, including the addition of two huge front vents and enlarging of the front-splitter and side skirts.
The car’s dimensions are 5260/2064/1406 mm, with a wheelbase of 3000m. The SU7 Ultra is notably wider and longer, due to its performance body-kit, than the standard SU7, while featuring the same wheelbase.
Nürburgring
Xiaomi aims to set a new record for in the four-door electric sedan class at Nürburgring. Currently, the fastest electric car around the Nürburgring is the Volkswagen ID.R with a lap time of 6:05.336 minutes. The fastest four door electric car around Nürburgring is the Porsche Taycan Turbo GT with a lap time of 7:07.55 minutes. The company aims to break the lap record at the legendary Nürburgring Nordschleife track in October.
Xiaomi currently only sells the standard Xiaomi SU7 in China, with their second retail model undergoing road tests. Chinese performance focused EVs are currently comprised of the 1247 hp Zeekr 001 FR and BYD’s 1287 hp YangWang U9. It’s unknown if the Xiaomi SU7 Ultra will ever be road certified, but with its 1578 hp and max speed of 350 km/h, it completely outshines the aforementioned models as the world’s fastest 4-door car.
BUGATTI TOURBILLON -1800HpCome on, if you are comparing a prototype, then add to the comparison all the prototypes and competitors that were already in the announcement.
The SU7 looks like a knock off version of McLaren with Tesla doors.
Better than both of those because this is a 4 door hypercar with 15000hp and does 0-100 in 1.9 seconds.
Can you design a car?
The ID R is half the weight, but it should beat the Taycan time.
