New Mercedes GLS vs BMW X7: verdict
Our verdict
While similar in size and virtually identical in practicality terms, these cars far from equal when it comes to the final reckoning.
The GLS is reasonably refined and loaded with kit – with particularly impressive safety equipment as standard – but its inconsistent interior quality and unsettled ride disappoint. It simply doesn’t live up to its billing as Mercedes’ flagship SUV.
The X7, meanwhile, totally delivers in every area, and then some. Outstanding inside and phenomenally relaxing on the road, it would be the clear winner even if it cost the same as the GLS. As it is, with financial factors so far in its favour, the big, brash and divisively designed X7 claims victory without breaking a sweat.
