BARCELONA – Move over, 911 Turbo S and electric Taycan Turbo GT.

With 850kW (1,140hp), the Cayenne Turbo Electric is the most powerful production car in Porsche’s history and it will leave almost any petrol-powered sports car in the dust – even with a boat hitched to the tow hook.

Despite being also the heaviest Porsche at 2.7 tonnes, the behemoth is quick, vaulting from 0 to 100kmh in 2.5 seconds. That matches the V12-powered Lamborghini Revuelto and is more than enough to knock the wind out of unsuspecting passengers.

Beyond sharing the name, the Cayenne Turbo Electric and the base 325kW (436hp) Cayenne Electric are barely related to the engine-powered Cayenne models which debuted in 2018.

Sitting on a dedicated electric vehicle (EV) platform, the new versions are offered in parallel to the existing petrol and hybrid Cayenne models, which use a different architecture.

The pair of Porsche EVs also perform well in terms of charging speed and range.

The battery capacity of both versions is identical at 113kWh. The Turbo Electric has 537km of range, while the non-Turbo can manage 5km more.

In the Singapore context, most drivers will not need to plug in more than three times a month, although it is unlikely that they will be maximising the Porsche’s 400kW charging capacity because most chargers here are a lot slower.

Between repeatedly verifying Porsche’s performance claims and pushing both versions through the serpentine roads outside Barcelona, I find that the test cars’ energy consumption rates and operating ranges are, predictably, nowhere near the claimed figures.

Actually, the handling of the electric Cayenne, in both Turbo and non-Turbo forms, is almost otherworldly. Whether it i...
