From a Porsche Macan Turbo SUV to an eBoat

18 Feb From a Porsche Macan Turbo SUV to an eBoat

(Oilandgaspress) – Porsche AG, Porsche Engineering, Studio F. A. Porsche, and boat-building company Frauscher have jointly developed the 850 Fantom Air—a sports boat with an electric powertrain that is based on standard components of the Porsche Macan Turbo. The project shows how Porsche Engineering is transferring automotive expertise to other sectors in order to establish innovative powertrain systems there as well.

Porsche AG took the lead in the project, and Philip Ruckert was appointed eBoat Project Manager by the Executive Board of Porsche AG. The technical foundation was laid together with Porsche Engineering. A short time later, the decision was made to integrate the project into the Macan model series and bring it to series production. Porsche Engineering was responsible for the technical implementation of the project content. “Only through close and trust-based cooperation with the individual specialist departments of Porsche AG have we succeeded, in just two years, in implementing a development that is ready for series production,” explains Thomas Warbeck, Specialist Project Manager at Porsche Engineering.

The special feature of the 850 Fantom Air is hidden in the hull: Instead of the usual petrol or diesel engine, this boat has a powerful electric powertrain. As in an all-electric vehicle, the powertrain delivers high torque from a standstill and at the same time makes the boat extremely quiet. The main components of the 800-volt powertrain—including the battery and drive module—originate from the rear-axle drive of the Macan Turbo. The passenger car components have been specifically adapted for marine use, as each sector has individual requirements that must be met by specific solutions. “In the automotive sector, we have built up in-depth know-how in technologically state-of-the-art developments.

The electrical components of the car engine, such as the stator and rotor, were adopted for the boat project unchanged. However, the motor housing has been newly developed. In cars, a gearbox is integrated into the motor casing to reduce the high engine speeds. In the boat, in contrast, the motor runs at a significantly lower speed of 6,000 rpm instead of the more than 16,000 rpm in a vehicle, which is why internal reduction was not required.

“We have developed and tested the new housing specifically to marine standards in terms of material selection and pairings, for example by means of adapted tests for salt spray, corrosion, and leaks,” explains Sebastian Riesbeck, Specialist Project Engineer at Porsche Engineering. The only gearbox in the powertrain is the standard boat Z-drive in front of the propeller, which reduces the speed to around 3,000 rpm.
