1.98 s to 100 km/h on Xiaomi's terms, 2.79 s to 60 on carwow's clock. 1,548 PS and a certified 7:04.957 at the Nürburgring.
Xiaomi claims the SU7 Ultra reaches 100 km/h (62 mph) in 1.98 seconds claimed, runs the quarter mile in 9.23 s claimed and tops out at 350 km/h (217 mph) claimed (Xiaomi, CarNewsChina). Xiaomi's own footnote says the 1.98 s leaves out the starting time and needs Pirelli Trofeo RS semi-slick tires. Converted to 0-60 mph, that's 1.91 s converted, the figure our race uses.
On a timing rig, carwow measured 2.79 s to 60 recorded (carwow) and ran 9.3 s in the quarter in two drag races recorded, beating a Tesla Model S Plaid and a Ferrari SF90 XX. The number with no asterisk is the lap: the Nürburgring certified 7:04.957 verified for a production SU7 Ultra with Xiaomi's track package on April 1, 2025 (Nürburgring). It's sold only in China, from RMB 529,900 claimed.
Xiaomi sold phones and rice cookers before it sold cars. Lei Jun, its founder, showed the SU7 Ultra prototype on July 19, 2024. The road car went on pre-sale on October 29, 2024 at RMB 814,900, then launched on February 27, 2025 at RMB 529,900, about $72,930 at the time claimed (CnEVPost).
Xiaomi says 10,000 orders, its target for the whole year, came in within two hours claimed (CnEVPost). It's sold only in mainland China. Xiaomi doesn't sell cars in the US and says it will start in Europe in 2027 reported (carwow).

Every figure carries its label. claimed means Xiaomi said it, without a published timed run. recorded means timed on an actual run: an instrumented test, a certified or verified record run, or a maker's own pass on a drag strip's timing system. verified means an official body, here the Nürburgring. reported is press we couldn't trace to a primary source. derived is our math. converted is a 0-100 km/h claim converted to 0-60 mph. Here's how we label numbers.
Each bar fills at the real speed of that car's 0-60 time, from the race's lineup. The SU7 Ultra's 1.91 s is Xiaomi's 0-100 km/h claim converted to 60 mph; the last bar is carwow's timed run.
Two things, by Xiaomi's own footnote: "0-100km/h 加速不包含起步时间，需搭配倍耐力® P ZERO™ TROFEO RS 半热熔轮胎。" It says the time doesn't include the starting time and needs Pirelli's Trofeo RS semi-slicks (Xiaomi). The semi-slicks aren't fitted at the factory. Xiaomi doesn't say how much starting time it leaves out; it works like the one-foot rollout American testers subtract.
Our race needs a 0-60 mph time, so we convert 1.98 s to 60 mph, which is 96.6 km/h: 1.91 s converted. It's a conversion, not a measurement. The one independent number is carwow's 2.79 s recorded, and carwow didn't say which tires or surface it used. No tester has published a trap speed.
The road car's official time is 7:04.957 verified, driven by Vincent Radermecker on April 1, 2025 and announced on June 11. It set the record for electric executive cars, timed with a notary present and the car checked by TÜV Rheinland (Nürburgring). It wasn't a bare showroom car: Xiaomi says it carried the Track Professional package, the carbon dual-duct hood, an aero underbody panel and Ring-approved safety parts (Xiaomi).
The stripped SU7 Ultra Prototype, on slicks with no interior, ran 6:46.874 claimed with David Pittard in October 2024, then 6:22.091 verified the same day as the road car's lap, the fastest official lap of 2025 in any class (Nürburgring). Lei Jun wrote that "this record will be broken again in the near future" (CnEVPost). It was, in its class: a Manthey-kitted Porsche Taycan Turbo GT ran 6:55.533 in May 2026 (Nürburgring).
At home, Xiaomi claims four-door production records at five Chinese circuits, including 2:09.944 claimed at the Shanghai International Circuit on February 13, 2025, with a roll cage fitted, against the Taycan Turbo GT's 2:11.28 (Carscoops), plus 1:41.806 at Zhuzhou, 1:26.741 at Chengdu Tianfu and 1:37.758 at Zhuhai claimed (ifanr).

Standard is aluminum. The RMB 42,000 carbon hood with two ducts deletes the front trunk, and in 2025 owners found the ducts did little. Since March 2026 Xiaomi fits two vanes inside them for free (CarNewsChina).
A V6s motor drives the front wheels. Carbon-ceramic discs sit behind 21-inch wheels, with six-piston fixed calipers in front and four in back, painted yellow.
The roof pod holds a lidar sensor for Xiaomi's driver assistance. A carbon roof comes only with the Track Professional package, and it replaces the glass roof.
A 93.7 kWh CATL Qilin 2.0 pack under the floor runs at 897 V, discharges up to 1,330 kW and charges at up to 5.2C, 10 to 80% in 11 minutes. CLTC range is 630 km.
Two HyperEngine V8s motors drive the rear wheels, each 425 kW and spinning to 27,200 rpm. With the V6s up front, the total is 1,138 kW and 1,770 Nm.
This fixed carbon wing is optional; the standard car has a wing that lifts at speed. The whole car makes up to 285 kg of downforce at 350 km/h, Xiaomi says.
Xiaomi claimed 9.23 s claimed for 400 meters when the car went on pre-sale, with no trap speed (CarNewsChina). carwow ran 9.3 s recorded twice. In the UK in September 2025 it beat a Model S Plaid's 9.5 s after cold tires spoiled its first launch and a later run hit a battery limp mode (autoevolution). In the UAE in January 2026, on a strip still dusted with sand, it beat a Ferrari SF90 XX's 10.2 s and covered the half mile in 14.5 s (Interesting Engineering).
Our race uses 9.20 s at 157 mph estimate, slightly quicker than both, which puts it 0.17 s behind the Lucid Air Sapphire.
Prices are Xiaomi's in China. None of them is sold in the US.
Five seats, the rising wing, an aluminum hood and road tires.
0-100 km/h on optional semi-slicks. Xiaomi gave 0-200 km/h as 6.09 s at launch (CnEVPost) and 5.86 s at the 2024 pre-sale (CarNewsChina).
Bilstein EVO R coilovers, Endless brake pads, forged wheels with road tires and semi-slicks, a carbon roof.
Add-on price reported by CnEVPost. The record car also had the ducted hood and an underbody panel.
Two seats: FIA carbon buckets, six-point harnesses and a half roll cage where the rear seats were.
Build numbers and changes from Xiaomi; price reported by CnEVPost. The cage and seats remove side airbags.
The power cap. In May 2025 a software update, version 1.7.0, held the car to about 900 PS until the owner set a qualifying lap on a Xiaomi-approved track, and added a 60-second wait for launch control. After owners protested, Xiaomi pulled it within days and said: "We appreciate the passionate feedback from our community and will ensure better transparency moving forward" (Carscoops).
The hood. The same month, tests showed the RMB 42,000 carbon hood's two ducts did almost nothing, unlike the prototype's. Xiaomi apologized on May 7, 2025 and offered buyers still waiting a switch to the aluminum hood and owners 20,000 points, worth about RMB 2,000; at least 300 owners asked for full refunds (CarNewsChina). After an earlier case that Xiaomi won on procedural grounds, in May 2026 a Jinan court found "exaggerated" marketing but no fraud and ordered one buyer's RMB 20,000 deposit returned (CarNewsChina). From March 10, 2026, Xiaomi fits two vanes inside the ducts for free (CarNewsChina).
The Chengdu crash. At about 3:16 a.m. on October 13, 2025, an SU7 Ultra crashed in Chengdu and caught fire, and bystanders couldn't open its doors (CnEVPost). The driver died. The forensic report put the impact at 167 km/h on an 80 km/h road and found the crash had cut power to the low-voltage system, which disabled the electronic exterior door releases; the driver died from the fire. Police held the driver fully responsible for drunk driving and speeding in February 2026, and the family disputes that (Gasgoo). A Chinese safety standard requires mechanical exterior door releases on new cars from January 1, 2027.
Sales. Monthly sales peaked at 3,101 in March 2025 and fell below 50 by December reported; Xiaomi disbanded the car's dedicated sales team at the end of January 2026 (CnEVPost). About 15,600 were sold from March through December 2025 derived, and 50 were registered in September 2026 reported (China EV Home).

Reaction split four ways. These are opinions, quoted with links.
"It's a miracle and a new beginning."Xiaomi EV, after the first prototype lap, CnEVPost
Lei Jun predicted the road car's record would fall soon, and Porsche obliged in May 2026.
"This car is fantastically easy to drive."Kevin Williams, InsideEVs
He drove it on a track near Beijing during the Beijing auto show.
"The steering is by far the best I've felt in any Chinese car."Mat Watson, carwow
carwow put the Chinese price at about £55,000 and guessed "more like £80,000" if it reaches the UK.
"Whether it's false advertising or poor communication by Xiaomi, the company should take responsibility for its mistakes rather than shifting the burden to consumers."SU7 Ultra owner group, CarNewsChina
The hood, the power cap and the Chengdu crash all landed in the car's first year, as sales fell to about 50 a month.
The consensus: nobody disputes that a phone company built a sedan quick enough to own a Nürburgring class record for a year, at a fraction of a Taycan's price. The arguments are about what you actually get: a 0-100 claim that needs semi-slicks, a quarter mile nobody has timed under 9.3 s, a record set with track options fitted, and a run of controversies that arrived as sales collapsed.

Xiaomi's footnote says the time requires Pirelli P Zero Trofeo RS semi-slicks, which the car isn't delivered on, and leaves out the starting time.
Order the RMB 42,000 carbon hood with two ducts and the front trunk is deleted.
The emblem is 24-karat gold set on carbon fiber.
The road car's 7:04.957 and the prototype's 6:22.091 were both driven on April 1, 2025, then announced two weeks apart in June.
No car of any kind posted a faster official Nordschleife time in 2025 than the SU7 Ultra Prototype's 6:22.091. A Ford F-150 Lightning SuperTruck was next at 6:43.482.
For a few days in May 2025, owners had to post a qualifying lap on an approved track before the car would give them more than about 900 PS.
In October 2026 racer Tomáš Vavřinec took a standard SU7 Ultra on its factory Pirellis to 323 km/h on the Hradec Králové airfield, a Czech record for a production car recorded.
The pack can deliver 1,330 kW, about 190 kW more than the three motors' combined 1,138 kW.
Xiaomi took pre-orders at RMB 814,900 in October 2024, then launched at RMB 529,900 four months later. The higher price returned for the two-seat Nürburgring edition.
In our quarter-mile model the SU7 Ultra finishes 14th of 21, using our 9.20 s estimate. The car just quicker and the car just slower:
Xiaomi claims 1.98 seconds from 0 to 100 km/h (62 mph), which converts to about 1.91 seconds to 60 mph. Xiaomi's footnote says the time excludes the starting time and needs Pirelli Trofeo RS semi-slick tires. The only independent timing we found, from carwow, was 2.79 seconds to 60 mph.
Xiaomi claimed 9.23 seconds for 400 meters when the production car went on pre-sale in October 2024, without a trap speed. carwow recorded 9.3 seconds in two separate drag races, one in the UK in 2025 and one in the UAE in 2026. Our race uses an estimate of 9.20 seconds at 157 mph.
The Nürburgring certified 7:04.957 for a production SU7 Ultra with Xiaomi's track package, driven by Vincent Radermecker on April 1, 2025, a record for electric executive cars. The Yangwang U9 Xtreme's 6:59.157 in 2025 was quicker but counts in a different class; within the electric executive class, a Porsche Taycan Turbo GT with a Manthey kit took the record with 6:55.533 in May 2026. The stripped SU7 Ultra Prototype lapped in 6:46.874 in 2024 and 6:22.091 in 2025.
Xiaomi claims 1,548 PS, or 1,138 kW, which is about 1,526 hp, with 1,770 Nm of torque. Two V8s motors of 425 kW each drive the rear wheels and a V6s motor drives the front. The 93.7 kWh battery can discharge at up to 1,330 kW.
It costs from RMB 529,900 in China, about $73,000 at launch in February 2025. The Nürburgring Limited Edition costs RMB 814,900. Xiaomi doesn't sell cars in the US and hasn't announced plans to; it says it will start selling cars in Europe in 2027.
In May 2025 owners found that Xiaomi's RMB 42,000 carbon hood with two air ducts didn't channel air the way its marketing suggested. Xiaomi apologized on May 7, 2025 and offered points or a switch to the standard hood. Chinese courts have ruled both ways, and since March 2026 Xiaomi has fitted free aero vanes inside the ducts.
Labels. Claimed: Xiaomi or Lei Jun said it, without a published timed run. Recorded: timed on an actual run: an instrumented test, a certified or verified record run, or a maker's own pass on a drag strip's timing system. Verified: an official body, here the Nürburgring, which times laps with a notary present and has TÜV Rheinland inspect the car. Reported: press reporting we couldn't trace to a primary source. Converted: a 0-100 km/h claim converted to 0-60 mph. Derived: our math. Estimate: modeled for our race because no published figure exists. Both are explained in the methodology guide. The race's 0-60 converts Xiaomi's 0-100 km/h claim; its 9.20 s at 157 mph is our estimate, since nobody has published a trap speed. Sources disagree in three places: Xiaomi's 0-200 km/h time appears as 5.86, 5.96 and 6.09 s; record dates at Chengdu and Zhuhai differ between Chinese press and Wikipedia; and December 2025 sales appear as 45 and 49. Compare it with every other car in the all-cars guide.
