In top-rung Turbo form, the dual-motor powertrain – with launch control activated – puts out a staggering 1140bhp and 1106lb ft of torque.
That equates to a blistering 0-62mph time of 2.5sec and a 0-124mph time of 7.4sec. Speed tops out at 162mph.
This power and speed puts the 2.5-tonne-plus SUV on par with hypercars such as the Bugatti Veyron and Aston Martin Valhalla.
It also surpasses the 1093bhp Taycan Turbo GT as the most powerful Porsche road car ever made, while placing it as the joint-third fastest Porsche alongside the latest 911 Turbo S. It is beaten only by the Taycan Turbo S (2.4sec) and Taycan Turbo GT (2.2sec).
Key to this extreme power is the Cayenne Turbo Electric’s rear motor, which features direct oil cooling – an innovation derived from motorsport that Porsche says ensures “high continuous output and efficiency”.
During normal driving, the Turbo model puts out up to 845bhp, with an extra 174bhp on offer (for 10sec at a time) via a ‘push to pass’ button on the steering wheel.
The entry-level EV is also equipped with a dual-motor drivetrain but with a much lower output of 402bhp – the same as is offered by the Macan 4 Electric.
With that decrease in power, the 0-62mph sprint is extended to 4.8sec and top speed reduced to 143mph.
Towing capacity for both models is rated at 3.5 tonnes.
Energy in both instances is supplied by a 113kWh battery. For the entry-level car, up to 398 miles of range is offered, with up to 387 miles in the Turbo.
That puts the Cayenne Electric above rivals such as the BMW iX and Lotus Eletre and what is expected from the incoming Range Rover Electric.
The PPE platform’s 800V electrical system means charging speeds can reach as much as 390kW via an appropriate DC charger. This means a near-200-mile top-up (10-80% charge) in less than 16 minutes. Up to 600kW of power can be achieved via braking recuperation.
