Porsche 935 (2019): A Comprehensive Guide

The 2019 Porsche 935, often referred to as the "935/19," is not a direct successor to the original 935 race car of the late 1970s. Instead, it's a modern, track-only homage to that iconic machine, built on the bones of the 991.2 generation 911 GT2 RS. Produced in a limited run of only 77 units, the 935/19 is a collector's item and a performance masterpiece, designed purely for private track days and club racing events.

This guide provides a comprehensive overview of the 2019 Porsche 935, covering its history, reliability, driving experience, and offering valuable buying advice for potential owners.

Generations: The 2019 Homage

Unlike a car with multiple production runs, the 935 (2019) effectively exists as a single, highly exclusive generation:

  • 2019 (935/19): Based on the 991.2 GT2 RS. Key features include:
    • Carbon fiber bodywork styled after the original 935/78 "Moby Dick".
    • 3.8-liter twin-turbo flat-six engine producing 700 horsepower.
    • 7-speed Porsche Doppelkupplung (PDK) transmission.
    • FIA-approved safety cage and racing bucket seat.
    • Exclusively for track use; not street legal.
    • Limited production of 77 units.

Reliability & Common Issues

Given the 935/19's track-focused design and limited production, long-term reliability data is scarce compared to road-going Porsches. However, we can infer potential issues and maintenance requirements based on its GT2 RS underpinnings and the demands of track use:

Engine

The 3.8-liter twin-turbo flat-six is a highly potent engine, but it requires meticulous maintenance, especially under track conditions:

  • Oil Changes: Frequent oil changes with high-quality synthetic oil are crucial. Consider changing the oil more often than the recommended interval, especially after track days.
  • Cooling System: Monitor coolant levels and temperatures closely. The 935/19's extreme performance can put a significant strain on the cooling system. Inspect hoses and connections for leaks regularly. Upgraded cooling solutions may be desirable for very hot climates or frequent track use.
  • Turbochargers: The turbochargers are a key component and potential point of failure. Ensure proper warm-up and cool-down procedures are followed to prolong their lifespan. Listen for any unusual noises or performance degradation, which could indicate turbocharger issues.
  • Fuel System: Use high-octane fuel and ensure the fuel system is properly maintained. Fuel injectors may require cleaning or replacement over time.

Transmission (PDK)

The 7-speed PDK transmission is generally robust, but track use can accelerate wear:

  • Fluid Changes: Follow Porsche's recommended PDK fluid change intervals meticulously. Consider shortening the intervals for track use.
  • Clutch Packs: The PDK's clutch packs can wear out over time, especially with aggressive driving. Monitor for any signs of slippage or jerky shifting.
  • Mechatronics Unit: The mechatronics unit controls the PDK's shifting functions. Problems with this unit can lead to shifting issues.

Chassis & Suspension

The 935/19's track-tuned suspension and chassis components require regular inspection and maintenance:

  • Suspension Components: Check for wear and tear on the suspension bushings, ball joints, and dampers. Consider replacing these components with upgraded track-focused parts as needed.
  • Brakes: The carbon ceramic brakes are incredibly powerful, but the rotors and pads will wear down over time. Monitor brake pad thickness and rotor condition regularly. Be prepared for the high cost of replacing carbon ceramic brake components.
  • Wheels & Tires: Track-focused tires are essential for optimal performance. Choose tires that are appropriate for the track conditions and your driving style. Inspect wheels for damage regularly.

Other Considerations

  • FIA Compliance: Ensure all FIA-approved safety equipment, such as the roll cage, seat, and harnesses, are in good condition and meet current regulations.
  • Data Logging: Utilizing the car's data logging system can help identify potential issues and optimize performance.
  • Professional Maintenance: Given the complexity and performance of the 935/19, it is highly recommended to have it maintained by a qualified Porsche Motorsport technician.

Driving Experience

Driving the 935/19 is an intensely focused and rewarding experience. It's a purebred track machine that demands respect and skill. Here's a breakdown of the driving experience:

Pros:

  • Incredible Performance: The 700 horsepower engine delivers breathtaking acceleration and top speed.
  • Precise Handling: The chassis and suspension are finely tuned for optimal track performance, providing exceptional grip and responsiveness.
  • Powerful Brakes: The carbon ceramic brakes offer phenomenal stopping power and resistance to fade.
  • Exclusivity: Owning one of only 77 935/19s is a unique and prestigious experience.
  • Visceral Experience: The car's raw power, aggressive styling, and track-focused design create an exhilarating and unforgettable driving experience.

Cons:

  • Track-Only: The 935/19 is not street legal and can only be driven on closed tracks.
  • High Running Costs: Maintaining and operating a high-performance track car like the 935/19 is expensive.
  • Demanding to Drive: The car's extreme performance requires a high level of driving skill and experience.
  • Limited Comfort: The interior is spartan and designed for racing, not comfort.
  • Potential for Damage: Track driving always carries the risk of accidents and damage.

Buying Advice

Purchasing a 935/19 requires careful consideration and due diligence. Here's some advice for potential buyers:

What to Look For:

  • Provenance: Verify the car's history and ownership. Look for a well-documented service history and evidence of proper maintenance.
  • Condition: Thoroughly inspect the car for any signs of damage or wear. Pay close attention to the bodywork, engine, transmission, suspension, and brakes.
  • Mileage: Track mileage can be more indicative of wear than total mileage. Consider the types of tracks the car has been driven on and the driving style of the previous owner.
  • Completeness: Ensure that all original parts and accessories are included with the car.

What to Avoid:

  • Cars with Significant Damage: Avoid cars that have been involved in serious accidents or have extensive damage.
  • Cars with Poor Maintenance History: A lack of proper maintenance can lead to significant problems down the road.
  • Modified Cars: Avoid cars that have been heavily modified, unless you are confident in the quality of the modifications.
  • Overpriced Cars: Research the market value of the 935/19 and be wary of cars that are significantly overpriced.

Key Considerations:

  • Inspection: Have the car inspected by a qualified Porsche Motorsport technician before making a purchase.
  • Track Support: Consider the availability of track support and maintenance services in your area.
  • Insurance: Obtain appropriate insurance coverage for a track-only vehicle.
  • Storage: Ensure you have a secure and climate-controlled storage facility for the car.

The 2019 Porsche 935 is a remarkable machine that offers an unparalleled track driving experience. With careful planning and diligent maintenance, it can be a rewarding and cherished addition to any collection.
