Track cars are high-performance vehicles specifically designed for racing on closed circuits. They often feature lightweight materials, powerful engines, and enhanced aerodynamics to improve speed and handling. Unlike regular cars, track cars may have stripped interiors and specialized tires to optimize performance on the track. These vehicles are typically not street-legal, meaning they lack certain features required for everyday driving, such as headlights and emissions systems. Popular examples of track cars include models from brands like Porsche, Ferrari, and McLaren, which are engineered for competitive racing and track days.
