Maximum Air-Cooled Force

Erbacher Ultimate Turbo


The Erbacher Ultimate Turbo is one of the flagship models of the brand. It represents the powerful turbo interpretation within the 964-based model world, combining classic turbo character with modern technology and Erbacher’s own visual language.

In all communication, the name Erbacher Ultimate Turbo should always be used. If an additional stylistic reference is required, the internal term Bad Boys may be mentioned. However, the primary designation should always remain the official model name.

Technically, the Ultimate Turbo is built around a 4.0-litre twin-turbo engine. At present, a power output of approximately 550 to 600 hp can be referenced. Further performance details such as torque, exact turbo specifications, or final driving data should only be communicated once engine development has been fully completed. It is important to note that while the Ultimate Turbo is already clearly defined as a vehicle concept, the engine itself is still in its final development stage, and this can be communicated accordingly.

Visually, the Ultimate Turbo should be understood as a distinctive, widened turbo interpretation with a clear Erbacher identity. Its design should not rely on any external or foreign model references, but instead stand firmly on its own as the Erbacher Ultimate Turbo. If needed, the internal character reference Bad Boys may be used. On the website, the vehicle should be presented as powerful, iconic, wide, modern, and technically uncompromising.

The interior of the Ultimate Turbo remains fully customisable. Suspension, brakes, gearbox, cooling systems, and additional technical specifications are still being developed internally. The key point is that the Ultimate Turbo should not be positioned as a simple power upgrade, but rather as a complete vehicle concept with its own distinct place within the Erbacher model world.

BODY

The body of the Erbacher Ultimate Turbo is developed to communicate and support its flagship performance status. A stronger stance, wider visual presence, and carefully integrated aerodynamic and cooling-related details give the vehicle a more assertive identity while preserving the core character of the air-cooled platform. Every exterior element is executed with premium craftsmanship and technical intent.

Interior

The interior of the Erbacher Outlaw is a deliberate departure from convention—raw, purposeful, and deeply driver-focused. Every element is stripped back to its essence, celebrating the mechanical honesty of a classic air-cooled driving machine while integrating subtle modern refinements where they matter most. Lightweight materials, exposed surfaces, and minimal insulation create an authentic, unfiltered connection between driver and machine. Hand-finished details, bespoke upholstery, and carefully selected components ensure that, despite its stripped-back nature, the cabin retains a distinct sense of craftsmanship and individuality. Instrumentation remains clear and analog in spirit, complemented by discreet enhancements for usability and precision. Seating is tailored for both control and comfort, designed to support spirited driving without compromising long-distance usability. The result is an interior that feels alive—unpolished in the best possible way—where every sound, vibration, and input is part of the experience. This is not about luxury in the traditional sense, but about purity, character, and an uncompromising connection to the road.
