According to Porsche, the big new Panamera - while still wrapped in light layers of pre-reveal camouflage - set the fastest time around the famed Nurburgring racetrack for a production sedan, with a time of seven minutes, 38 seconds.
Powered by a 4.0-litre twin-turbocharged V8 petrol engine, the new Panamera Turbo offers 404kW of power and 770Nm of torque, sent to its all-wheel drive system via an eight-speed dual-clutch (PDK) transmission.
Porsche claims a 0-100km/h time of 3.8 seconds for the Panamera Turbo, which can be improved to 3.6 seconds by ticking the option box for the Sport Chrono package. Top speed is a claimed 306km/h.
Beating the previous sedan record of 7:39 - set only recently by the Alfa Romeo Giulia QV - the new Panamera has also outdone some legendary supercars such as the Lamborghini Murcielago LP640, Ferrari F430 Scuderia and the Lexus LFA.
The 7:38 lap time also makes the new Panamera Turbo 14 seconds quicker around the torturous German circuit than the previous-generation Panamera Turbo S, which set a time of seven minutes 52 seconds back in 2011.
Australians looking to buy the fastest production sedan in the world can order a new Panamera Turbo now, which starts at $376,900 plus on-road costs. Deliveries will commence in the first quarter of 2017.
