Porsche, famend for mixing its wealthy heritage with forward-thinking innovation, lately achieved a exceptional feat by setting a brand new car altitude document. In December, a specifically modified 911 Carrera 4S, underneath the expert management of triple Le Mans winner Romain Dumas, conquered Ojos del Salado in northern Chile. This volcano, the very best on this planet, witnessed the 911 reaching an unprecedented altitude of twenty-two,093 toes, a testomony to Porsche’s engineering prowess and adventurous spirit.
This record-setting undertaking, born from a 2019 dialogue between Klaus Zellmer, then President of Porsche North America, and Frank Walliser, Vice President of Car Dynamics, was designed to have a good time the thirtieth anniversary of the 964 Carrera 4. The primary all-wheel-drive 911, the 964 Carrera 4, represented a major milestone in Porsche’s historical past, and this new achievement was a becoming homage.
Two distinctive 911s have been crafted for this problem: ‘Doris’ and ‘Edith’. Each automobiles featured a groundbreaking suspension system initially developed for the 919 Hybrid Le Mans racer. Nonetheless, Edith, the record-setting car, was distinguished by Porsche’s inaugural steer-by-wire system and a major discount in weight by the usage of superior supplies.
In line with Porsche’s philosophy, the core powertrain elements – the twin-turbo 3.0-liter flat-six engine and the seven-speed guide transmission – remained unaltered from the Carrera 4S. The actual innovation lay within the guide management of energy distribution, permitting the motive force to modify between rear-wheel and all-wheel drive. This function, mixed with a bespoke locking differential system, was pivotal in tackling the demanding situations of Ojos del Salado.
The visible dominance of the 34-inch mud-terrain tires on each automobiles was unmistakable. These tires, along with portal axles and a novel gearing association from Tibus, drastically altered the automobiles’ capabilities, remodeling them into one thing far faraway from any normal Porsche mannequin. Regardless of these intensive modifications, the driving expertise retained acquainted components of the Porsche 911. The format of the controls within the Altitude 911s remained typical of the model, though Edith’s cabin was stripped again for its document try, emphasizing performance over consolation.
The ‘Warp Connector’ suspension system, initially meant for the 919 Le Mans racer however by no means used, marked a major departure from normal Porsche setups. This method, that includes interconnected springs and dampers, supplied distinctive stability and responsiveness over tough terrain. The ‘SpaceDrive’ steering system in Edith, devoid of conventional steering suggestions, was engineered to supply precision and management, essential for navigating the difficult volcanic panorama.
The efficiency of those automobiles was a revelation. The distinctive gear ratios and superior suspension programs facilitated an unparalleled driving expertise. The rear-engine format, a defining attribute of the 911, contributed considerably to their stability and traction, even on probably the most difficult off-road programs. The distinction in weight between Doris and Edith grew to become more and more evident in demanding conditions. Edith, benefiting from intensive weight-saving measures, demonstrated superior agility and management, particularly on steep descents the place engine braking was essential.
Following their historic ascent, Doris and Edith are at the moment being transported again to Porsche’s headquarters, destined for a spot of honor within the firm’s museum. Nonetheless adorned with the Chilean dust from their exceptional journey, these automobiles stand as symbols of Porsche’s enduring dedication to innovation and journey. As they take their place within the museum, they won’t solely commemorate a major achievement but in addition encourage future generations to proceed pushing the boundaries of automotive engineering and exploration.
