The Frauscher × Porsche 850 Fantom Air uses the Macan Turbo’s 100 kWh battery and motor, delivering 536 hp on water with bespoke marine engineering.

The new Frauscher × Porsche 850 Fantom Air is an electric speedboat that borrows its powertrain from Porsche’s upcoming all‑electric Macan Turbo SUV [4]. The collaboration repurposes the SUV’s 100 kWh lithium‑ion pack and permanent‑magnet motor for marine use, creating a 536‑horsepower vessel that promises high‑speed performance on water.

**Key takeaways**  
- The boat shares the Macan Turbo’s 100 kWh battery and motor architecture [4]  
- Power output on water is rated at 536 hp (400 kW) with a capped 6,000 rpm propeller drive [4]  
- Engineers added a steel‑cable damping frame to protect the battery from wave impact [4]  
- Charging required a software workaround to satisfy the vehicle’s parking‑brake logic [4]  
- The project is a joint effort between Porsche and Austrian boat builder Frauscher, known for electric vessels since 1955 [3]

## Marine adaptation of a road‑ready powertrain  

Porsche’s electric Macan Turbo, slated for 2026, uses a 100 kWh pack and a permanently excited synchronous motor that spins up to 16,000 rpm on land [1]. For the 850 Fantom Air, Frauscher engineers retained the motor’s stator and rotor but built a new housing to limit rotation to 6,000 rpm, then routed power through a standard Z‑drive that reduces shaft speed to a more suitable 3,000 rpm for a boat propeller [4]. This modification preserves the high‑power density of the automotive motor while preventing the excessive rpm that would be unsuitable for marine propulsion.

To address the harsh marine environment, the battery is mounted in a load‑bearing frame with steel‑cable damping, a “high‑tech hammock” that mitigates the constant pounding of waves and protects the pack from damage [4]. Because the original Macan’s control software expects a parking brake signal before allowing charge, Frauscher’s engineers created a “rest‑bus simulation” that tricks the system into thinking the boat is parked, enabling the 800‑volt architecture to accept charging on the dock [4].

## Why it matters  

The 850 Fantom Air demonstrates how high‑performance electric automotive technology can be translated to marine applications, offering a quiet, high‑power alternative to traditional gasoline‑powered speedboats. By leveraging Porsche’s upcoming EV platform, Frauscher accelerates the development timeline and showcases the versatility of the Macan Turbo’s battery and motor system [3][4]. The project also highlights the engineering challenges of adapting land‑based EV components for water, such as rpm reduction, battery protection, and software integration. As electric propulsion gains traction in the boating sector, the Fantom Air may set a benchmark for future high‑performance electric vessels.
