Porsche has taken a significant step forward in the development of its electric vehicles by testing the Cayenne EV virtually using AI and simulations more extensively than ever before. This innovative approach has resulted in several key benefits for the company.
One of the most notable advantages of this virtual testing is the significant reduction in the number of physical prototypes that needed to be built and subsequently destroyed during the testing phase. By utilizing computer simulations and artificial intelligence, Porsche was able to save approximately 120 prototypes from being constructed and then discarded after testing. This not only saves time and resources but also minimizes the environmental impact of the development process.
The electric Cayenne was developed around 20% quicker than previous models, thanks to the extensive use of virtual testing. This accelerated development timeline will allow Porsche to unveil its first electric Cayenne later this year, alongside the combustion model. The Cayenne EV will be built on the same 800-volt Scalable Systems Platform (SSP) as the electric Macan but with a faster development process due to the advanced testing methods.
Porsche’s Deputy Chairman, Michael Steiner, highlighted the success of the virtual testing approach, stating that the company was able to go directly from digital complete vehicle testing to pre-series production. This streamlined process eliminated the need for early prototype construction and allowed engineers to conduct digital test drives and verify the results with real-world test bench tests.
In addition to virtual testing, Porsche also utilized virtual reality to give designers and engineers a preview of how various parts would look and function before they were physically built. The company even tested vehicles virtually on accurate digital replicas of roads and tracks like the Nurburgring Nordschleife.
While technology continues to improve and reduce the need for human intervention in testing, Porsche emphasizes the importance of human oversight in the final stages of development. Sascha Niesen, the vehicle testing boss at the Porsche Development Center in Weissach, emphasized the role of humans in adding the finishing touches to the testing process.
Despite the advancements in virtual testing, there are still some aspects of testing that require physical prototypes, such as charging in extreme temperatures. Engineers need to evaluate how quickly the Cayenne EV can replenish its range in various conditions, which is crucial for ensuring optimal performance.
The Cayenne EV is expected to offer fast-charging capabilities, with a peak charging power rating of 400 kW and a consistent charging curve that can take the battery from 10% to 80% in just 16 minutes. The vehicle will also support wireless charging at up to 11 kW, providing a convenient option for charging without the need for cables or wall boxes.
In conclusion, Porsche’s extensive use of AI and simulations in the development and testing of the electric Cayenne has not only accelerated the development process but also saved resources and minimized the environmental impact. The company’s commitment to innovation and efficiency in the electric vehicle market is evident in the success of the virtual testing approach.
