Yahoo Autos Porsche Built A 911 With Portal Axles To Go Where Unimogs Can't Reach
No car has ever driven at higher altitude than this 992-generation Porsche 911 Carrera 4S with portal axles. On Saturday the Porsche crew, led by racing driver Romain Dumas, reached the highest peak of the west ridge of the Ojos del Salado volcano in Chile, after doing an exploratory run up to 19,000 feet in 2022. That’s the tallest active volcano in the world, for anyone keeping track, stacking up at just over 22,000 feet above sea level. The new 911 C4S still has its stock 3-liter turbo flat-six engine and 7-speed manual transmission.
Racing driver Romain Dumas has conquered basically every discipline of motorsport where he’s driven. He’s got wins in the 24 Hours of Le Mans, Pikes Peak Hillclimb, 12 Hours of Sebring, 24 Hours of Nurburgring. He’s won an FIA rally championship. He’s placed at the Dakar rally. He owns the electric lap record at the Nurburgring. The guy’s done it all, so now I guess he’s set his sights on breaking more records.

The lead car received a very special additional piece of technology – steer by wire – developed and provided by Schaeffler Group. The system called Space Drive was capable of meeting the unique and extreme demands of the volcano and the terrain, offering precision and detailed feedback to allow Romain Dumas to place the car precisely where he needed it – often while ascending precarious and near-vertical slopes.
22,000 feet is a massive height. For context, the highest paved road in the world is the Karkoram highway between China and Pakistan, at roughly 16,000 feet. Pikes Peak in Colorado is just 14,115 feet by comparison. I’ve had altitude sickness at the top of Pikes Peak, so I can’t fathom climbing another 8,000 feet above that. The team took two weeks to reach the summit, as they would only climb a little each day to slowly acclimate to the increased altitude. Two doctors went along for the ride to keep track of the team’s health. That’s probably for the best.
