Xiaomi dazzles with the SU7 Ultra: the most radical version of the electric saloon from the Chinese manufacturer

Xiaomi, the Chinese manufacturer until recently known only for its consumer electronics products and which has also recently entered the automotive industry with the launch of the SU7, has just unveiled a hyper-sporty version of the latter, which it has named the SU7 Ultra. Xiaomi says that with this prototype, whose series production has not yet been confirmed, the company’s aim is none other than to put on track the fastest four-door vehicle in the world based on a production model.

With the SU7 Ultra, the Chinese manufacturer has gone all out, more than doubling the power of the SU7 Max version to deliver a total of 1139 kW from the three electric motors it integrates. It is therefore no surprise that the SU7 Ultra can accelerate from 0 to 100 km/h in just 1.97 seconds, or from 0 to 200 km/h in 5.96 seconds. Its top speed is also impressive, capable of reaching 350 km/h, as is its braking capability. Xiaomi claims the motors can provide up to 0.6G of regenerative braking force, or up to 2.36G when combined with the disc brakes, allowing it to come to a complete stop in just 25 metres when travelling at 100 km/h.

All the body panels of the SU7 Ultra are made of carbon fibre to reduce weight, which will obviously increase the price of the vehicle if it is ultimately taken into series production. However, thanks to this it is much lighter than any other hypercar with which it can be compared, tipping the scales at a total of 1,900 kg.

As might be expected, the SU7 Ultra is slightly wider and longer than the SU7 Max, as a result of the integration of modified panels to improve the aerodynamics and performance of the vehicle. Xiaomi has also equipped this electric hypercar with a large rear wing that is capable of generating 2,145 kg of downforce.

The SU7 Ultra comes with CATL’s most advanced battery technology

For the time being the Chinese manufacturer has not specified the capacity of the battery pack it fits. What we do know is that this Ultra version of the SU7 uses CATL’s new Qilin II technology, which allows a charge from 0 to 100% in 12 minutes with a charger operating at 897V. This CATL battery pack can also deliver more than 800 kW of power even at 20% charge, which should allow the vehicle to offer outstanding performance on the track, provided Xiaomi’s engineers have also integrated a good cooling system to control the temperature of the cells.

As we have already mentioned, the Chinese manufacturer wants the SU7 Ultra to be the fastest four-door vehicle in the world and, to prove it, it plans to take it to the Nürburgring in October to try to set a new lap record. Currently, at the Nürburgring, in the electric vehicle category this record is held by the Volkswagen ID.R, although if we look only at electric four-door models the fastest is the Porsche Taycan with 7 minutes and 7 seconds.
