What is the widest car?

The widest car title is often contested and depends on how you define "widest" (e.g., including mirrors, excluding mirrors). However, a strong contender for the title of widest production car is the Mercedes-Maybach S-Class, with a width that often exceeds 80 inches (over 2 meters) depending on the exact specifications and optional equipment. Some modified or custom cars might be wider, but they wouldn't be mass-produced.
