Porsche has revealed the Cayenne Turbo Electric, and while yesterday’s headlines focused on its colossal power output, another stat is arguably even more staggering: this is the heaviest production Porsche ever made. At 2645kg, the fully electric Turbo variant outweighs every model the brand has produced, including hybrids, SUVs, and even the company’s existing EVs.
Yet despite carrying more mass than any Porsche before it, the Cayenne Turbo Electric has another surprise: it’s quicker in a straight line off the mark than the legendary 918 Spyder.
Heavier than any Porsche in history
The previous heavyweight champ was the Cayenne Turbo E-Hybrid Coupe, which tipped the scales at 2595kg. Even that combustion-assisted SUV was heavier than all Porsche EVs to date, including the Taycan range and the electric Macan. The new Cayenne adds another 50kg and a lot of that comes down to the enormous 113kWh battery pack, which alone weighs around 600kg.
More power than any Porsche, too
With launch control engaged, the Cayenne Turbo Electric delivers an astonishing 1139hp and 1500Nm making it the most powerful production Porsche ever.
And while you’d expect something weighing nearly 2.6 tonnes to need a geological timeframe to get moving, the reality is the opposite.

Quicker on launch than a 918 spyder
To make the point, Porsche staged a drag race between the Cayenne Turbo Electric and the 918 Spyder. In the short sprint, the electric SUV is actually faster: it reaches 100km/h in 2.5 seconds, one-tenth ahead of the hybrid hypercar and on par with the current 911 Turbo S.
Beyond 200km/h the tables turn, with the 918 regaining its lead, but Porsche’s message is clear — instant electric torque delivers brutal acceleration, even when the vehicle is carrying supertanker levels of mass.
The promo video (jump to 11.25mins in the above clip) pairs Mark Webber with Formula E development driver Gabriela Jílková, the run theatrically ending in a draw. But the real headline is simple: Porsche’s heaviest car ever can out-drag one of its most iconic halo cars.

Not the quickest Porsche, though
In pure 0–100km/h terms, the Cayenne Turbo Electric isn’t the brand’s quickest. That honour belongs to the Taycan Turbo GT with the Weissach Package, which clocks a 2.2-second sprint.
But as a demonstration of what electric drivetrains can do, and how far the Cayenne nameplate has evolved, Porsche’s fattest model proving quicker off the line than a 918 Spyder might be the most surreal performance milestone yet.
