The Lamborghini Miura: A Comprehensive Guide

The Lamborghini Miura, produced between 1966 and 1973, isn't just a car; it's a legend. It's widely considered the first true supercar, setting a new standard for performance, design, and sheer visual drama. Born from the maverick vision of Ferruccio Lamborghini and brought to life by the genius of engineer Gian Paolo Dallara and designer Marcello Gandini at Bertone, the Miura challenged Ferrari's dominance and firmly established Lamborghini as a force to be reckoned with. It occupies a unique position as a mid-engine, two-seat sports car, designed primarily for high performance driving.

Generations and Evolution

While often discussed as a singular model, the Miura evolved significantly throughout its production run. Key iterations include:

  • P400 (1966-1969): The original Miura. Characterized by its stunning Bertone design, transversely mounted 3.9L V12 engine producing 350 bhp, and a top speed of around 170 mph. Early models had some teething issues with handling and stability at high speeds.
  • P400S (1968-1971): An improved version of the P400. Power was increased to 370 bhp. Interior refinements included power windows and available leather upholstery. Brakes were also improved. Handling was slightly improved but still retained some inherent challenges.
  • P400SV (1971-1973): The ultimate Miura. Distinguishable by its wider rear track, lack of "eyelashes" around the headlights (although some retained them), and a more powerful 385 bhp engine. The engine also featured separate lubrication for the engine and gearbox, addressing a major weakness of earlier models. The SV is generally considered the most desirable and refined Miura.
  • Jota (1970): Technically not a generation but a one-off experimental version developed by Bob Wallace, Lamborghini's test driver. It featured extensive weight reduction, a significantly more powerful engine (estimated at over 440 bhp), and a revised suspension. The Jota was unfortunately destroyed in an accident, but it inspired several Miura SVs to be modified to "Jota" specifications.

Reliability & Common Issues

Owning a Miura requires dedication and a deep understanding of its engineering. They are complex machines that demand meticulous maintenance. Here are some key areas of concern:

  • Engine Lubrication (P400 & P400S): The original Miuras shared the engine and gearbox lubrication. This was a significant design flaw, as metal shavings from the gearbox could contaminate the engine oil, leading to premature wear and failure. This is THE primary issue with early cars. Conversions to separate lubrication are highly recommended and greatly increase reliability.
  • Cooling System: The Miura's cooling system can struggle, especially in hot climates. Overheating is a common issue. Regular maintenance and upgrading the radiator are essential. Check for signs of leaks and corrosion.
  • Braking System: While the brakes were improved over time, they are still rudimentary by modern standards. Inspect brake lines, calipers, and rotors for wear and corrosion. Consider upgrades for improved stopping power if you plan on driving the car frequently.
  • Electrical System: Italian cars of this era are notorious for their unreliable electrical systems. Check for corrosion, loose connections, and faulty wiring. Consider a comprehensive rewire if necessary.
  • Rust: Check thoroughly for rust, especially around the wheel arches, sills, and undercarriage. The Miura wasn't known for its robust corrosion protection.
  • Chassis: Inspect the chassis for signs of damage or repair. Accident damage can significantly affect the car's value and handling.
  • Originality: Many Miuras have been modified over the years. Ensuring originality is crucial for maintaining its value. Verify the engine number, chassis number, and other key components. Seek expert advice when verifying authenticity.
  • Gearbox Early models suffer from relatively weak synchros, and can be difficult to shift smoothly even when in good condition. The later SV with split sump helped improve this, and is considered a much better gearbox.

Driving Experience

Driving a Miura is an unforgettable experience. It's a visceral and engaging machine that demands your full attention. However, it's not for the faint of heart.

Pros:

  • Stunning Design: The Miura is arguably one of the most beautiful cars ever made. Its design is timeless and instantly recognizable.
  • Exhilarating Performance: The V12 engine delivers exhilarating performance, with a thrilling soundtrack.
  • Rarity and Exclusivity: The Miura is a rare and highly sought-after car, making it a true collector's item.
  • Engaging Driving Experience: The lack of modern driver aids creates a raw and engaging driving experience that connects you directly to the machine.

Cons:

  • Challenging Handling: The Miura's handling can be unpredictable, especially at high speeds. It requires skill and experience to drive safely. Early models are especially prone to lift-off oversteer.
  • Demanding Maintenance: The Miura requires frequent and meticulous maintenance, which can be expensive.
  • Uncomfortable Interior: The interior is cramped and lacks modern amenities.
  • Reliability Issues: As mentioned above, the Miura is prone to various mechanical and electrical issues.

Buying Advice

Buying a Miura is a significant investment. Here's some advice to help you make an informed decision:

  • Year to Look For: The P400SV (1971-1973) is generally considered the most desirable and refined Miura, offering the best performance and reliability. The separated lubrication system is a huge advantage.
  • Years to Avoid (Potentially): The P400 (1966-1969), while historically significant, suffers from the most significant reliability issues, particularly the shared engine and gearbox lubrication. These are still fantastic cars, but budget for a split sump conversion.
  • Condition is Key: Prioritize condition over originality. A well-maintained Miura is worth more than a neglected one, even if it's slightly less original.
  • Expert Inspection: Before making a purchase, have the car thoroughly inspected by a Lamborghini specialist. They can identify potential problems and assess the car's overall condition.
  • Verify Authenticity: Ensure the car is authentic and that all key components match the factory specifications. Check the engine number, chassis number, and other identifying marks.
  • Check Service History: Review the car's service history to see how well it has been maintained. Look for evidence of regular maintenance and repairs.
  • Drive It: If possible, take the car for a test drive to assess its handling, performance, and overall condition.
  • Budget Accordingly: Factor in the cost of ongoing maintenance and repairs when budgeting for a Miura. These cars are expensive to maintain.
  • Consider Jota Conversions: While not factory originals, well-executed Jota conversions can offer a significant performance upgrade. Be sure to research the quality of the conversion work.

The Lamborghini Miura is a true automotive icon. Owning one is a privilege and a responsibility. With careful research, expert advice, and a healthy dose of dedication, you can experience the thrill of owning one of the greatest supercars ever made.
