This is the new Porsche Cayenne Coupe Electric, the fully expected and racier-looking spin-off of the upcoming Cayenne Electric large SUV.

It’s only the second coupe-shaped variant of the German automaker’s largest model across all four generations of Cayenne since 2002, following on from the original Cayenne Coupe which arrived in 2019.

Like the existing petrol-powered Cayenne Coupe which continues on sale, it shares much with its donor model, but the sweeping ‘flyline’ roof – which Porsche gamely compares to the look of a 911 – renders the newcomer 24mm lower overall than the SUV.

In the other dimensions – including a length of 4985mm, wheelbase of 3023mm and almost 2.2 metres of width from mirror to mirror – the Coupe is identical to the Cayenne Electric.

However, that slippery shape improves the aerodynamic form of the Cayenne Coupe Electric, reducing the coefficient of drag down to 0.23 from 0.25Cd. This has a positive effect on range, which we’ll come back to.

Like the SUV, the Cayenne Coupe Electric has active aerodynamics, including cooling-air flaps in the front bumper, extendable vertical side spars which emerge at either edge of the rear bumper and an active spoiler.
