Which luxury brand became a Mercedes-Benz sub-brand in 2015?

The luxury brand that became a Mercedes-Benz sub-brand in 2015 was Maybach.

Maybach began as a German engineering company founded in 1909 by Wilhelm Maybach and his son Karl. Daimler-Benz acquired the company in 1960, and the name later returned as a standalone ultra-luxury automobile brand in 2002. That revival struggled commercially and ended as a separate marque after 2013.

Daimler revived the name again in a new form: Mercedes-Maybach. The company announced the sub-brand in November 2014, and the first Mercedes-Maybach S-Class models arrived in 2015. They were positioned above the regular Mercedes-Benz S-Class, emphasizing rear-seat comfort, elaborate materials and chauffeur-oriented luxury.

Maybach is sometimes mistaken for AMG because both names identify Mercedes-related premium divisions. Their roles differ: Mercedes-AMG focuses mainly on high-performance vehicles, while Mercedes-Maybach represents exceptional luxury and refinement. The Maybach name now appears on selected S-Class, GLS and other flagship models.
