Xiaomi, the world’s second largest smartphone maker, just lately launched its electrical sportscar, the Xiaomi SU7 sedan. Now, the corporate has simply introduced it is going to quickly try a quick lap on the Nürburgring Nordschleife utilizing a devoted SU7 track-ready prototype.

Xiaomi’s founder and CEO, Lei Jun 雷军, as we speak (July nineteenth) held the corporate’s annual presentation to point out off new merchandise. Throughout the first ~70 minutes, Lei Jun instructed the story of the inception and improvement of Xiaomi’s first auto, the SU7 EV, which was launched in late March 2024.

The story included Lei Jun’s strategy of personally driving over 180 different auto fashions through the improvement strategy of the SU7. He additionally obtained a racing licence and spent lots of time on racetracks, as did round 100 different members of Xiaomi’s automobile engineering staff. This enabled them to shortly develop their experience in automobile dealing with and efficiency, and iteratively apply enhancements to the SU7 throughout its improvement.

The 4-door sports activities sedan, which begins from RMB 215,900 (€27,270 or $29,700) is already an in a single day success, promoting at a charge of over 11,400 models per 30 days.

After additionally spending time presenting Xiaomi’s new smartphones and different client merchandise, in the direction of the tip of the present, Lei Jun introduced “yet one more factor.”

He revealed that the corporate has been engaged on a prototype track-focused variant of the SU7, known as the “Extremely.”

The Extremely has already been largely designed, constructed, and undergone observe testing, however its parameters and dynamics are being additional developed and improved.

As soon as the SU7 Extremely observe prototype has set a benchmark Nürburgring Nordschleife lap time, deliberate for someday in October 2024, Xiaomi will finalise the design and specs of a road-legal retail model of the Extremely. It will go on sale someday in 2025.

What are a number of the efficiency specs of the observe prototype Xiaomi SU7 Extremely?

It has a complete of 1,548 horsepower, from 3 electrical motors. In depth use of carbon fibre has allowed Xiaomi to maintain the automobile weight right down to 1,900 kg — spectacular for a robust 4-door BEV. For context, the Tesla Mannequin S Plaid weighs 2,162 kg, and the newest Porsche Taycan Turbo GT weighs 2,234 kg. Each have considerably much less energy than the SU7.

On the similar time, the SU7 Extremely prototype’s racecar aerodynamics give it an enormous downforce of two,145 kg at excessive pace, which ought to make for some spectacular grip via high-speed corners.

The facility-to-weight ratio provides the automobile spectacular acceleration, with 0 to 100 km/h taking simply 1.97 seconds (sooner than the Tesla or the Porsche). Equally spectacular, 200 km/h comes up in simply 5.96 seconds! High pace is over 350 km/h (>218 mph).

We have now mentioned Porsche’s EV lap instances, and Tesla’s lap instances, on the ‘ring beforehand, so if you’re not acquainted with this iconic race observe (and why it’s broadly used for automobile improvement), take a look at these articles. What lap time will the Xiaomi SU7 Extremely prototype do on the Nürburgring Nordschleife?

A lot will rely upon how highly effective the SU7 Extremely’s cooling techniques are, and thus how a lot of the lap distance these unbelievable headline 1,436 horsepower can be found for. Each the Tesla, and even the newest Porsche, are thermally restricted on a single lap of the ring, when pushed to their most energy. Because of this, when known as upon for ~7 minutes (and ~20 km) of this demanding observe, the powertrain cooling (for some mixture of motors, inverters, and battery pack) can get overwhelmed and the automobile compensates by decreasing the system energy output.

In the event you watch the Porsche Taycan Turbo GT lap, for instance, you may see a number of locations (notably at Kesselchen and Dottinger Hohe) the place the automobile’s 10 second “enhance mode” is requested however unavailable as a result of automobile already being at its thermal limits. That is regular stuff — there’s at all times a steadiness in mechanical techniques between energy output and thermal limits (in addition to interacting with different components like effectivity and reliability).

On the finish of the day, the Taycan and the Mannequin S Plaid are designed primarily as highway automobiles, and solely a really small fraction of householders will ever push them to ranges that bump up in opposition to the cooling functionality that the engineers lastly settled on.

Lap instances additionally rely loads on the selection of tires. Producers of highway automobiles, like Porsche, often take the sincere and clear resolution of saying official ‘ring lap instances that are run on the identical tires that are provided on the market to regular clients of the showroom automobile. Musk made the rookie mistake of hinting about lap instances which have been in the end solely achievable on race compound tires, which have been thus by no means achieved through the formally sanctioned lap time on avenue tires.

Xiaomi might be not aspiring to promote this actual track-special prototype model to common clients as a road-going automotive. It subsequently might in principle run with race-biased rubber (like Trofeo R or Pilot Sport Cup 2 R) and declare that’s legit as a result of this can be a race automotive. In that case, a time of beneath 7 minutes ought to be nicely inside attain. That is as a lot due to the light-weighting and downforce as anything.

With a road-biased sport tire (like P-Zero, or Pilot Sport Cup 2), which is much less sticky and extra lengthy lasting, round or simply over 7 minutes would already be spectacular.

As talked about above, as soon as the staff has discovered setup with the prototype for the October lap time efforts, Xiaomi will transfer on to designing, manufacturing, and promoting a road-legal model (which is able to probably need to have barely much less aggressive aero) to fulfill highway security (particularly pedestrian security) laws. They will even probably run this on street-biased rubber.

If the ultimate road-going model of the SU7 Extremely can get anyplace near the lap time of the Porsche Taycan GT, that will likely be a exceptional achievement for the primary automotive Xiaomi has ever made. You too can guess that the corporate will worth it to undercut the Taycan!

We must wait and see.

Twist of Destiny

Lei Jun recounted that the corporate’s journey to launching its first automobile began on January 15, 2021. Why this date?

In 2014, Lei was named businessman of the yr by Forbes, and in 2019 acquired a nationwide award for “Excellent Builder of Socialism with Chinese language Traits.” (This isn’t unusual — for instance, BYD’s chairman Wang Chuanfu has additionally acquired this nationwide recognition.)

The US authorities — which has been famously hostile to Socialism and labour actions for the reason that late nineteenth century, and significantly hostile to China — determined to answer that award by banning Xiaomi from getting funding from throughout the US, and in the end, from doing enterprise within the US, as reported by the Wall Avenue Journal at the moment.

This restriction was put in place on January 14, 2021, proper on the finish of the Trump administration, and thereafter saved in place by the Biden administration. It was this hostile transfer by the US authorities which triggered Xiaomi to discover new areas of enterprise — by aiming to make an car — and to maintain its staff employed.

This, and different attention-grabbing particulars, are recounted in as we speak’s presentation, which you’ll watch on Xiaomi’s web site. The lengths the corporate went to with a view to study through the improvement course of are noteworthy, and go a protracted method to explaining how a client electronics firm was in a position to make its first ever auto such an instantaneous success story.
