The Alfa Romeo 166 is a large executive car produced by the Italian automaker Alfa Romeo from 1998 to 2008. It was the successor to the Alfa Romeo 164, and was positioned as a rival to the BMW 5 Series, Mercedes-Benz E-Class, and Audi A6. The 166 was designed by Walter de Silva, and featured a distinctive Italian styling that combined elegance with a sporty feel. It was offered in a range of body styles, including a four-door sedan and a five-door station wagon, known as the Sportwagon. The 166 was praised for its stylish design, comfortable interior, and enjoyable driving dynamics. It was also equipped with a range of innovative features for its time, including a multi-link rear suspension, a powerful V6 engine, and an optional Q2 electronic limited-slip differential.

Powering the 166 was a range of petrol and diesel engines, with displacements ranging from 2.0 liters to 3.2 liters. The 2.0 TB model featured a turbocharged 2.0-liter four-cylinder engine that produced 155 horsepower and 184 lb-ft of torque, providing a balance between performance and fuel economy. The 166 was also available with a 3.0-liter V6 engine that generated 220 horsepower, offering a more powerful driving experience. The 166 was known for its smooth and refined ride, thanks in part to its independent suspension system. The car's handling was also praised, with precise steering and good body control. Despite its elegant design, the 166 possessed a surprising level of practicality, offering ample passenger and cargo space. While the 166 achieved a level of success, it ultimately faced challenges in the competitive European luxury car market. Despite its strengths, it was arguably overshadowed by its German rivals in terms of reliability and long-term durability.
