The most obvious way to put an automotive electric powertrain into a boat is to find a hull that fits and start adapting. Frauscher took the opposite approach with the 790 Spectre, developing an entirely new hull around the complete drive system from the Porsche Macan Turbo and treating that module as the fixed point from which everything else follows.

The hardware is transplanted largely unchanged. The 100 kWh high-voltage battery, 400 kW rear-axle PSM motor and control electronics are packaged as a single unit within the 7.97-metre hull, in the same way Porsche has structured its own BEV platforms rather than adapting existing architectures. Frauscher built the new hull lighter, shorter and narrower than previous models in the range to suit the Macan module rather than the other way around. The Frauscher x Porsche Fantom, which picked up multiple awards in 2025, had already proved that automotive-grade BEV hardware can handle marine operating conditions. The 790 Spectre advances that by starting the hull design from scratch.

Inside, the cockpit borrows directly from Porsche convention in ways that go beyond decoration. The start button is to the left of the wheel, the steering wheel is trimmed in Porsche leatherette, the driver and front passenger seats carry the Porsche Crest, and the primary readout comes from five round instruments using traditional Porsche graphics. For an owner moving between the Macan and the 790 Spectre, the familiarisation task is minimal by design.

Porsche used boot Düsseldorf to show the 790 Spectre alongside the Macan Turbo Concept Lago, a one-off built to mirror the boat in both finish and material language. Both wear Darkteal Metallic from the Paint to Sample programme, applied to the hull at the Frauscher yard as an 11-layer finish. The Concept Lago pulls marine references into the SUV in return: real wood across both luggage compartments, door trims and floor mats; a compass replacing the Sport Chrono stopwatch; marine-grade seat fabric against Crayon leather bolsters; and matching Darkteal Metallic keys for both products. It is a design study for the personalisation programmes rather than a production vehicle. The 790 Spectre is available to order now.

Also at the show was the Cayenne Electric making its German debut, with the Turbo variant rated at up to 850 kW and a tow capacity of up to 3.5 tonnes. Porsche is making the commercial logic explicit: a fully electric SUV capable of hauling a boat and trailer in the same weight class as the 790 Spectre, completing a purchase that stays entirely within the BEV ecosystem.
