Externally, the Porsche Panamera Signature Edition shares largely the same design language as the 2024 Panamera Executive Long Wheelbase. Notably, the new model comes standard with the Sport Package – resulting in a more motorsport-inspired look for its front bumper.

Under the hood, the Porsche Panamera Signature Edition retains the 2.9-liter twin-turbocharged V6 engine. On paper, this powertrain delivers a maximum output of 353 hp and a peak torque of 500 Nm, enabling a 0-100 km/h acceleration time of approximately 5.2 seconds. Meanwhile, thanks to the standard rear-axle steering system on the Signature Edition, it doesn’t compromise the driver’s driving dynamics—even with the same dimensions as the Executive Long Wheelbase.

Objectively speaking, the all-new Porsche Panamera Executive Long Wheelbase is far more cost-effective than the previous generation. After all, as we mentioned earlier, the new standard features would cost over ¥200,000 if added as options. On top of that, the Panamera Signature Edition shares the underpinnings of the Executive Long Wheelbase, with spatial performance matching the previous-generation Executive Long Wheelbase – which is why the Signature Edition is essentially the all-new Executive Long Wheelbase variant. Ultimately, for young executives considering a large luxury executive grand tourer (GT), the Porsche Panamera Signature Edition is truly a worthwhile choice.
