This year marks exactly 50 years since the Lamborghini Miura P400 SV came onto the scene. Although the Miura was already five years old in 1971, the SV version took things to a whole new level with aesthetic and drivetrain upgrades. The Miura SV is the fastest, most powerful, and rarest version of the Italian marque’s first mid-engined supercar.

The Miura SV (V is for veloce, or super-fast) was the last evolution of the successful project codenamed P400. The SV was meant to accompany the S but was so popular that it actually wound up replacing it. Lamborghini says the Miura SV is now the most sought-after of its production cars and that it is the “highest expression of the supercar concept of its time and the best of all the Miura versions produced.”

Production of the Miura SV ceased in early 1973 after just 150 were produced. An exception was made two years later when a final car was built for Formula 1 team owner Walter Wolf. That car is now at Mudetec, Lamborghini’s museum in Sant’Agata Bolognese.
