Challenger 3057 Graphite Edition

A motorhome with generous space, but at an appealing price

Published on 05/02/2026


We tested the Challenger 3057 Graphite Edition, the flagship model from the French manufacturer. It is a generously sized motorhome, guaranteeing ample interior space, yet it comes to market at a price that is not particularly high when compared with the various models crowding the A-class motorhome category. It measures almost seven and a half metres in length, offers four homologated travel seats and three sleeping places, which increase to five with the optional front drop-down bed. This makes the Challenger 3057 Graphite Edition an appealing choice for two people who want to travel in comfort, but who also occasionally enjoy having one or two guests on board. There is no shortage of garage space, while on board there is a comfortable rear sleeping area and an equally comfortable living area with a face-to-face dinette.
