Porsche Taycan Turbo GT gets Manthey kit and beats Xiaomi SU7 Ultra record
The Porsche Taycan Turbo GT with Weissach Package set a new Nürburgring Nordschleife lap time of 6 min 55.533 sec with a new Manthey Kit, beating the previous electric luxury saloon record held by the Xiaomi SU7 Ultra by more than nine seconds.
Porsche and Manthey developed the first Manthey Kit for the Taycan Turbo GT. The package was created for the Taycan Turbo GT with Weissach Package and Porsche says it will be available from June as a retrofit option.
The run took place on the 20.832 km Nürburgring Nordschleife. Porsche development driver Lars Kern recorded a time of 6 min 55.533 sec, 12 seconds quicker than his previous lap in the standard Taycan Turbo GT with Weissach Package. According to the Nürburgring, the record was confirmed with official timing and under notarial supervision.
The Xiaomi SU7 Ultra set a time of 7 min 04.957 sec in 2025 in the same Electric Executive Car class. Porsche’s new result is more than nine seconds quicker.
This is a class record, not a blanket claim
The category matters. Porsche is not simply claiming the title of the world’s fastest electric car. This is a record for electric executive cars. Official Nürburgring records sit within defined classes, and every result depends on production status, equipment and classification.
The Manthey package is not a styling exercise. Porsche says downforce at 200 km/h rose from 95 kg to 310 kg. At the new top speed of 310 km/h, the Taycan Turbo GT with Manthey Kit produces around 740 kg of downforce in its track setting.
The package includes a large new rear wing, an optimised front diffuser, a more effective rear diffuser, underbody aerodynamic parts and carbon aerodynamic covers for the rear wheels. The car also gets lighter 21 inch forged wheels, wider track tyres, larger brake discs and recalibrated Porsche Active Ride, all wheel drive and steering systems.
More than a bigger wing
Unlike earlier Manthey packages, Porsche also changed the powertrain this time. Updates to the high voltage battery, control unit and inverters raised maximum current from 1100 amps to 1300 amps. Output climbed to 600 kW, while Attack Mode briefly provides up to 730 kW. With Launch Control, torque rises to 1270 Nm.
That makes the story bigger than one Nürburgring number. In the development of electric performance cars, raw power alone no longer settles the argument. A fast lap now comes from battery thermal management, inverter strategy, software, tyres and aerodynamics working as one system. The Manthey Taycan shows how electric car tuning is moving away from simple add on parts and towards deeper engineering.
Xiaomi’s SU7 Ultra record was awkward for Porsche. A Chinese technology company, with its first major production car, managed to attack territory that European performance brands have long treated as their own. Porsche’s reply did not arrive as a cheap show of force. It came as a factory backed partner package aimed at serious track users with serious budgets.
That does not make the Taycan a direct mass market rival to Xiaomi. It does, however, send a clear message. Porsche does not intend to hand the electric performance car record table to Chinese manufacturers without a fight.
