Porsche has been spotted testing a top-tier 911 Safari over the past year, but this isn’t that vehicle. What you’re looking at is a purpose-built 911 off-roader built to take on the tallest volcano in the world, Chile’s Ojos del Salado, which peaks at 22,615 feet.

Porsche built two of the sturdy 911s, both based on the Carrera 4S. They were led by a team led by endurance racer and adventurer Romain Dumas to explore the limits of the 911. Dumas and his team reached a height of 19,708 feet, which is impressive given the thin air, temperatures as low as -22. degrees F, and a total absence of roads.

The highest value a vehicle has reached on the volcano is 21,961.94 feet, set by a pair of Mercedes-Benz Unimogs in 2020. That figure is an altitude record for the climb achieved by a wheeled vehicle.

The task of making a lowered sports car like the 911 that could handle the rocky and icy terrain of the volcano’s slopes was Michael Rösler, chief engineer of the 911.

The car’s engine, a 3.0-liter 6-cylinder twin-turbo with a nominal power of 443 hp, was already able to cope well with thin air, which is about half the density of air at sea level. Consequently, the main focus was on modifications designed to handle the rough terrain.

The key modification was the portal axles, which increased ground clearance to nearly 14 inches and required widened wheel arches to be fitted. The 911’s 7-speed manual transmission remains, but has been fitted with lower gear ratios to allow for precise and gentle throttle inputs at low speeds. The new ratios also work well with the large off-road tires that have been fitted, according to Porsche.

Porsche also installed a device called Warp-Connecter. Adapted from motorsports, the device allows constant wheel loads even when the frame undergoes extreme movements and, as a result, improves traction. Differential locks and a Steer-by-Wire system have also been added.

For safety reasons, the cars were equipped with roll-bars, carbon fiber bucket seats, harnesses and a winch. An underbody protection was also installed, made of aramid fiber, to allow it to slide over the rocks.

While Porsche doesn’t plan to put such a robust 911 into production, the automaker is expected to launch a more capable version in the near future. Prototypes spotted in the wild featured higher ground clearance and a fixed rear wing.
