While Alfa Romeo was establishing itself as one of the premier sporty-car makers of Europe, the company was also quietly perfecting its take on the sedan. This fact was evidenced in 1998 by the introduction of the 166, the successor to the 164. Penned by Walter de Silva, the 166's svelte lines were to become the cornerstone for the look of future Alfa Romeo cars. The face resembled that of the popular 156, highlighted by the trademark triangular grille adorned with the Alfa Romeo logo. Despite being categorized in the highly-competitive E segment, which included the likes of the luxurious Mercedes-Benz E-Class and BMW 5 Series, the 166 stayed true to its sporting nature.
