The Shelby Cobra 427 is a high-performance sports car developed in the 1960s through a collaboration between American automotive designer Carroll Shelby and British manufacturer AC Cars. It is one of the most recognized classic sports cars and a defining model of the American performance era.

The Cobra 427 features a lightweight roadster body mounted on a reinforced chassis and is powered by a large-displacement 427 cubic inch (7.0-liter) V8 engine. Power is delivered to the rear wheels through a manual transmission. The combination of a powerful engine and relatively low vehicle weight resulted in exceptionally strong acceleration for its time.

The design is characterized by a long hood, short rear deck, and open-top configuration. Produced in limited numbers, the Shelby Cobra 427 has become a highly sought-after collector vehicle and remains an iconic symbol of 1960s American sports car engineering.
