In December, Le Mans legend Romain Dumas was on the wheel of the extremely modified Porsche 911 Carrera 4S that broke the altitude record for wheeled automobiles. But Dumas isn’t the one connection this record-setting 911 has to the legendary 24-hour enduro. Its trick suspension was initially meant for Le Mans.
While a lot of this Carrera’s drivetrain is unmodified, its suspension has been completely redone, geared up with a system Porsche calls the Warp Connector. Originally created for the Le Mans-winning 919 Hybrid, it was shelved early on in that automobile’s growth and unused till this venture.
It’s not like the suspension system in some other Porsche.
How It Works
Instead of letting every nook function independently, the Warp Connector suspension goes in the wrong way, interconnecting all 4 corners for optimum traction. The entrance axle and rear axle are every related transversely to their very own centrally mounted springs and dampers. For the entrance axle, that spring and damper setup is positioned beneath the hood, simply in entrance of the windshield cowl. For the rear axle, the spring and damper might be discovered on the rear of the cabin, the place you’d usually discover the parcel shelf.
Above, a 3D diagram of the Warp Connector suspension supplied by Porsche.
The “connector” within the Warp Connector is the ultimate piece of the puzzle. It’s a stable bar that connects every axle longitudinally by way of a sequence of pivot factors. The bar creates a form of twist rigidity between the entrance and rear, so if one axle articulates a sure manner, the bar enacts a power onto the opposite axle, coaxing it to articulate in the wrong way.
This means any upward power going right into a wheel — say, one tire driving over a giant rock — is translated into downwards power to the opposite three wheels. The reverse wheel receives its downward power by way of the centralized spring and damper, whereas the alternative axle receives its downward forces by way of the Warp Connector bar. The system’s interconnected nature means all 4 corners are performing on one another always, pushing one another to remain related to the floor under. The result’s a 911 that may preserve its stability over massive rocks, dips, and undulations. Here’s an indication of the system in motion:
Engineers have been hesitant to assemble a full-size prototype with such a drastically completely different suspension setup. So they constructed a scale mannequin first.
“[The suspension’s] inventor came with the idea to build an RC model car with exactly the same system,” says Sven Schaarschmidt, chassis engineer for the record-setting automobile. “It looked a bit different than in the real car, but the working principle was exactly the same thing. We were able to play with the car on a desk, moving the wheels and looking at all the connections. It gave us an idea if it could really work in a big car.”
One query stays: If the Warp Connector works so nicely on this 911, why was it dropped from the 919 venture?
“The problem was that [the 919 engineers] had a number of other issues to solve with the car,” Schaarschmidt informed Motor1. “To make it easier to analyze all the issues, They wanted to simplify the car and remove the system. Then the car was working so well that they saw no reason to bring it back.”
Porsche received’t say whether or not it plans to do extra with the Warp Connector idea, although contemplating simply how a lot area it takes up within the record-setting 911, viable manufacturing functions are seemingly few and much between. Still, it’s a formidable little bit of engineering that’s value highlighting. It helped obtain a world document, in spite of everything.
If we needed to guess, the Warp Connector’s reappearance would seemingly are available a motorsport software, seeing as that’s the place it originated, anyway. Race automobiles don’t want to fret about occupying a bit of further cabin or cupboard space, making it an interesting selection for competitors use. But that’s simply hypothesis on our finish.
