The RML P39 Hypercar is an extraordinary evolution of the Porsche 992 Turbo S, reimagined and enhanced by British engineering expertise from RML Group. Built on the foundation of Porsche’s high-performance 992 Turbo S model, the P39 merges over four decades of motorsport and engineering heritage to create a hypercar that redefines power, aerodynamics, and control. Powered by a specially developed twin-turbo flat-six engine, the hypercar offers up to 920 horsepower in sport mode and adjustable power settings tailored to different driving conditions, including a wet mode for safer handling.

Key Insights

  • Engine Performance and Customization: The P39’s twin-turbo flat-six engine output of up to 920 hp represents a seismic leap beyond the standard Porsche 992 Turbo S. Its ability to modulate power levels—including a sporty 920 hp mode, a standard drive mode at 750 hp, and a cautious 600 hp wet mode—illustrates a modern approach to performance where extreme power is balanced with practical driveability and safety according to conditions. This reflects an understanding that hypercars must be adaptable, not just powerful.
  • Advanced Aerodynamics as a Performance Multiplier: The significant increase in downforce—from 432 newtons stock to over 6,500 newtons at 150 mph—dramatically transforms the car’s handling at high speeds. Active aerodynamic elements such as the adjustable rear wing and movable front splitter not only improve grip but also optimize drag reduction and turning dynamics. This level of sophistication in aerodynamics highlights how crucial airflow management is to hypercar performance, especially when pushing the envelope of speed and stability.
  • Bespoke Engineering Approach: RML’s transformation of the 992 Turbo S platform into the P39 exemplifies bespoke engineering, where a production car’s DNA is reimagined with custom parts, advanced materials, and racing-derived technologies. The wholly rebuilt carbon fiber body and redesigned suspension with wider track width are examples of how the company meticulously refines every element, ensuring the final product is not just faster but significantly more dynamic and responsive. This approach contrasts with typical aftermarket tuning by offering greater integration, quality, and exclusivity.
  • Versatility Through Drive Modes and Systems: The incorporation of three drive modes combined with a hydraulic lift system enhances the car’s usability across diverse scenarios, from daily driving to track assaults. This versatility addresses a common limitation of many hypercars which tend to be uncompromisingly track-focused. By balancing performance with comfort and adaptability, the P39 aims to be a rare hybrid—a brutal hypercar that can also manage the demands of real-world driving environments. This forward-thinking design enriches ownership experience and broadens the car’s appeal.
  • Limited Production as a Strategic Choice: Limiting the production run to 39 units elevates the P39 from a high-performance vehicle to a collector’s trophy. This scarcity enhances the vehicle’s exclusivity and desirability, positioning it among the rarefied ranks of bespoke hypercars. Limited numbers also suggest a level of craftsmanship not typically found in mass-produced sports cars, underscoring RML’s dedication to precision and quality rather than volume.
  • RML Group’s Motorsport Heritage Influence: RML’s four decades of motorsport experience underpin the P39 project, which enables the company to incorporate race-proven engineering solutions into a road-legal hypercar. This heritage is evident in the car’s chassis development, aerodynamics, suspension tuning, and powertrain enhancements. Motorsport pedigree not only informs performance but also aids credibility, signaling to prospective owners and enthusiasts that the P39’s capabilities are backed by real-world racing expertise.
  • Redefining Porsche Tuning and Hypercar Boundaries: By pushing the already formidable Porsche 992 Turbo S platform to new extremes, RML challenges conventional perceptions of what Porsche tuning can achieve. The P39 is not simply an upgraded Turbo S; it is a hypercar that redefines limits with its aggressive power, advanced aerodynamic systems, and bespoke design. This sets a bold precedent for future hypercar development—where collaboration, precision engineering, and customization create machines far beyond the sum of their parts.

In conclusion, the RML P39 hypercar exemplifies the pinnacle of performance tuning and bespoke automotive engineering. It deftly combines race-derived technology, advanced aerodynamics, and a flexible powertrain within an exclusive, carbon-fiber supercar framework. Through considered innovation and meticulous craftsmanship, the P39 sets a new standard for Porsche-based hypercars and offers insight into the future direction of ultra-high-performance automotive design.
