If you weren’t already taking Chinese automakers seriously, today is a good day to start. If comments made by Xiaomi’s boss are true, the smartphone maker’s new electric sedan has just annihilated the Porsche Taycan’s Nurburgring lap record.

Not broken, not smashed. Annihilated. CEO Lei Jun told his Weibo followers the hardcore 1,527 hp (1,548 PS) SU7 Ultra lapped the Nordschleife in 6:46.874, according to Reuters. If true, that would make it more than 20 seconds faster than a Taycan Turbo GT with the Weissach Pack that includes a rear-seat-delete. One of those lapped the Ring in 7:07.55 last year to become the fastest four-door car.

Even Rimac’s quad-motor Nevera hypercar, the fastest production EV at the track, could only manage 7:05.20. And although Rimac now has a more extreme version with improved aero that should take a good chunk out of that time, it’s going to look lame if it can’t topple the SU7.

Other famous track-ready two-door cars the Ultra beats include the 2023 Porsche 911 GT3 RS (6:49.33), 2020 Mercedes-AMG GT Black Series (6:48.05) and Pagani Zonda R (6:47.50).

Xiaomi is expected to reveal the Ultra in full later today when we’ll get confirmation of the Ring time and more details about the car’s powertrain, chassis, and aero features. The automaker revealed a concept version of the Ultra in July that generated up to 2,145 kg (4,729 lbs) of downforce and weighed just 1,900 kg (4,189 lbs), making it roughly 465 kg (1,025 lbs) lighter than a Porsche Taycan Turbo GT.

A triple-motor setup fired the concept to 62 mph (100 km/h) in 1.97 seconds, to 124 mph (200 km/h) in 5.97 seconds, and past the 186 mph (300 km/h) mark in 15 seconds. How much of that concept package is present on the production car we should know before the day is out.
