Porsche CEO Michael Leiters is drawing a distinction between his company’s sports-car strategy and Tesla’s ($TSLA) dramatic Roadster demonstration, saying Porsche wants to avoid “effects and shows.” Speaking at a Berlin automotive conference on Wednesday, Leiters emphasized engineering and the connection between a driver and a car. His comments followed Tesla’s October 15 presentation, which featured a Roadster prototype performing an airborne rotation using thrusters. Elon Musk (@elonmusk) celebrated the demonstration and has discussed autonomous tricks and a looping track at Tesla’s Texas headquarters. Leiters argued that Porsche’s Mission S concept and the Roadster are aimed at different customers. Tesla describes three Roadster configurations: Performance, Thrust and Rocket. The company says the Rocket version uses cold-gas thrusters and is not approved for public-road use. Musk has pointed to 2028 for production, but firm delivery timing and final pricing remain unresolved. Porsche unveiled Mission S on the same date as Tesla’s event. The mid-engine concept sits above the 911 in the company’s intended lineup and can accommodate hybrid or combustion power. Leiters described prospective customer interest as strong. The rivalry highlights two approaches to a flagship car: an attention-grabbing technology demonstration and a more traditional premium sports-car proposition. Both still face the practical challenge of turning an ambitious concept into a vehicle customers can actually buy.
