The Alfa Romeo 166 is an executive car that was produced by the Italian automaker Alfa Romeo from 1998 to 2008. It was designed to be a competitor to luxury sedans like the BMW 5 Series, Audi A6, and Mercedes-Benz E-Class, and served as a replacement for the Alfa Romeo 164. The 166 was known for its stylish design, sporty handling, and refined interior. It was offered in a variety of engine options, including petrol and diesel units, ranging in power from 155 to 240 horsepower. The 166's design was penned by Walter de Silva, known for his work on other iconic Alfa models like the 156 and the Brera. The 166 featured a sleek, aerodynamic profile with a distinctive grille, flowing lines, and a wide stance.

Inside the cabin, the 166 offered a luxurious and spacious environment with high-quality materials, comfortable seats, and a comprehensive range of features. The 166's interior emphasized driver-centric design with a focus on both comfort and performance. It incorporated a driver-oriented cockpit with a sporty steering wheel, well-placed gauges, and ergonomic controls. The 166 was available with a variety of standard and optional features, including power windows and locks, climate control, leather upholstery, sunroof, navigation system, and a premium sound system. Despite its sleek design and luxurious features, the Alfa Romeo 166 struggled to gain the same level of sales success as its German competitors. This was largely due to a combination of factors, including its relatively high price, perception of reliability issues, and limited availability in some markets. The 166 was discontinued in 2008, paving the way for the Alfa Romeo 159, another stylish and sporty executive sedan.
