The Lamborghini Countach was first unveiled to the world at the 1971 Geneva Motor Show. After three prototypes and a great deal of development work, the first iteration of the Countach, the LP400, hit the streets in 1974. The Countach featured angular, wedge-shaped styling, accented by use of trapezoidal shapes throughout the design. While the Countach evolved greatly in terms of design over the course of its production, the original Marcello Gandini styling remained evident. The unique scissor doors, a first for a production car, featured throughout all variants. While later designs focused on the addition of spoilers and aerodynamically inspired additions, the initial design featured clean, unfettered lines, making early Countachs very distinguishable from later models. Produced from 1974 until early 1991, the Countach went through five major evolutions: The LP400 (1974-1978), the LP400 S (1978-1982), the LP500 S also known as the LP5000 S (1982-1985), the LP5000 QV (1985-1988), and the 25th Anniversary Edition (1988-1991). Originally powered by Larmborghini's 4L V12, during the course of production, the engine saw various developments that saw it increase in size and power, with the LP500 S using a 4.8L V12, and the LP5000 QV and 25th Anniversary Edition using a 5.2L V12. With nearly two thousand cars produced, the Countach not only cemented Lamborghini's place in Italian automotive royalty, but its unique and futuristic design laid the foundations for all Lamborghinis to come. For 2022, a limited production, modern version of the Countach known as the LPI 800-4 saw a run of 112 examples built.
