Specifications

4.0L Twin-Turbo V8

AMG's hand-built 4.0-litre twin-turbo V8 making 577 hp, retuned for Maybach to prize effortless, refined thrust over raw aggression.

Each engine is assembled by a single master technician at AMG in Affalterbach under the 'one man, one engine' principle.

Built under AMG's 'one man, one engine' philosophy, each carries its builder's signature.
Maybach softens the tune for smoothness rather than the AMG SL’s sharper edge.
