In a public confrontation reflecting the deep contrast in engineering philosophies between automotive giants, Michael Leiters, CEO of Porsche, leveled sharp criticism at Tesla and its CEO Elon Musk, describing the stunts of the "flying" Roadster as mere "effects and shows" that Porsche completely avoids. These statements came during a technical conference held in Berlin, where Leiters emphasized that his company prefers to focus on tangible technical innovation rather than pursuing media sensationalism.
Clash of Philosophies: Innovation vs. Spectacle
This criticism coincided with the unveiling of the flagship cars of both companies on the same day. While Tesla showcased its "Roadster" jumping in the air and spinning using compressed air bursts, Porsche unveiled the "Mission S" model, a mid-engine supercar aimed at redefining high performance away from the noise of visual shows. Leiters explained that the two cars do not target the same class of customers, noting that Porsche strives to build cars that deliver genuine engineering innovation that can be driven on the roads.
Technical Details of Tesla's Flying Car
Tesla revealed three versions of the new "Roadster," each relying on different propulsion technologies aimed at achieving unprecedented acceleration figures:
- Performance Class: Utilizes underside suction fans to increase traction and achieve 0 to 60 mph acceleration in under 1.6 seconds.
- Thrust Class: Adds cold-gas thrusters at the rear, reducing the acceleration time to under 0.9 seconds.
- Rocket Class: A track-only version equipped with thrusters all around the car, currently not authorized for public road driving.
Why Does This Trend Spark Technical Debate?
The real challenge in Tesla's "flying" car lies in the laws of physics governing the operation of cold-gas thrusters. Technically, these thrusters act like a massive tank of compressed air; the "Rocket" version carries about 400 liters of air at a pressure of up to 10,000 psi, which weighs about 200 kilograms of gas.
Despite the immense power produced by these thrusters, their efficiency remains time-limited; the tanks empty completely within a few seconds of intensive use, while compressor recharging takes between six to seven hours. This technology also raises concerns regarding massive noise levels that could cause hearing damage to those surrounding the car when the thrusters are activated.
What Changes Practically for Users?
While Tesla bets on attracting audiences through features that seem inspired by science fiction movies, Porsche returns to its roots in the ultra-exclusive car category. The "Mission S" may be available with a hybrid powertrain or an internal combustion engine, directly targeting competition with Ferrari. This division illustrates that the supercar market is heading in two directions: Tesla's path, which integrates aerospace technologies with electric vehicles, and Porsche's path, which focuses on refining traditional and hybrid mechanical engineering to achieve the highest degrees of practical performance.
