The Cayenne Turbo Electric Breaks a Radical Record: Porsche’s Heaviest Car in History

Its battery alone weighs almost as much as a Porsche 356 SL–and the numbers don’t stop surprising.

Porsche has just rewritten its own rulebook. After debuting yesterday as the most powerful production Porsche ever, the new Cayenne Turbo Electric adds another astonishing title: it is officially the heaviest Porsche ever built, tipping the scales at 5,831 pounds (2,645 kg). For a brand forged under the banner of lightweight engineering, the figure is as shocking as it is revealing of the EV era the industry is entering.

A 113-kWh battery that weighs like a whole classic Porsche

The numbers speak for themselves. The Turbo Electric carries a 113-kWh battery pack weighing 1,322 pounds (600 kg)–a staggering mass comparable to an entire Porsche 356 SL, the lightweight icon that won its class at the 1951 24 Hours of Le Mans. Despite incorporating this colossal energy pack, the Cayenne Turbo Electric still delivers breathtaking performance, with 1,139 hp and 1,106 lb-ft of torque when launch control unleashes its full potential.

Even more surprising is that it outweights the already hefty Cayenne Turbo E-Hybrid Coupe, the previous record holder at 5,721 pounds (2,595 kg). It also surpasses all other electric Porsches, including the Taycan lineup and the second-generation Macan. And while it may be the porkiest model ever to come out of Zuffenhausen, global rivals show just how extreme the segment has become.

Compared to other heavyweight EV SUVs, the Cayenne almost looks modest. Mercedes’ electric G-Class comes in at a colossal 6,801 pounds, the EQS SUV follows closely, and American giants like the Cadillac Escalade IQ push the scale to an unbelievable 9,134 pounds (4,143 kg). Even lighter alternatives such as the Rivian R1S still exceed Porsche’s figure, highlighting how the quest for massive batteries and mega-range is reshaping the market.

Historically, the Cayenne has never been a featherweight. The original 2002 model–developed during Ferdinand Piëch’s era of complex, over-engineered projects–already weighed 5,191 pounds in Turbo S form, thanks to its true off-road hardware: low-range gearbox, locking rear differential and advanced suspension systems. But today’s trend signals something bigger: Porsche is preparing for an even heavier future.

The brand is currently developing a three-row SUV, initially set to be electric-only but now launching first with combustion engines. Once the EV version arrives, its seven-seat configuration will almost certainly push Porsche’s weight record beyond the new Cayenne Turbo Electric. One thing is clear: the battle between performance, luxury and electrification is redefining Porsche’s limits like never before.
