As of 2015, there are approximately 20 models that have been produced by Lamborghini. These models range from the 1964 350GT to the 2015 Huracán.
The 135 350GT model was produced between 1964 and 1966. It featured a V12 engine and a top speed of 158 miles per hour. That top speed was later tamed in 1966 by the 400GT 2+2, which was also built off of a V12 but only reached 155 miles per hour. The Miura was also introduced in 1966, and production lasted until 1972, longer than any of the models prior. This model helped propel Lamborghini into motor sports after the vehicle's potential was discovered in a racing environment.
Lamborghini introduced many different models during the late 60s and 80s, such as the Espada, Islero, Jarama, Urraco and Silhouette. Out of all of the models to come out during that period, none are as iconic as the 1974 Countach. This model received numerous face lifts and performance increases over its 16-year lifespan, which ended in 1990. Its top speed of 191 miles per hour made it the fastest Lamborghini developed up to that point.
Lamborghini has continued to move in the direction of performance and has introduced many other models between the 90's and 2015. A few worth noting are the Diablo, Murciélago, Gallardo, Aventador, and Sesto Elemento.
