Full review

The old Sprinter had plenty of appeal but it had its flaws. The brand-new Mercedes is a big step forward and could challenge the Volkswagen Crafter for top-of-the-class honours. And now there’s a new version of the Grand Canyon S, Hymer’s sole Merc-based campervan offering in a Fiat Ducato-dominated line-up.

The layout is carried over – and it’s the European favourite of a transverse rear double bed, half-dinette lounge with swivel cab seats and central bathroom and galley. Neat and interesting details like the folding dining table and optional elevating roof (turning this into a practical four-berth) are continued, too.

As before, the slimmer Mercedes bodyshell means that Hymer has had to add an exterior pod on the nearside to give enough length for the bed. The resulting double measures 1.95m by 1.35m and the mattress sits on cup springs for added comfort. The roof bed is ‘maxi-sized’ too.

Being a Merc, you get assistance systems such as Crosswind Assist, Hill Start Assist and ESP, as well as a tilt and reach-adjustable steering column and multi-function steering wheel. A seven-speed automatic gearbox is offered, as are an engine upgrade from 143 to 163 or 190bhp, adaptive cruise control, LED headlights, electric closing of the side door, Mercedes’ new MBUX multi-media system, and even four-wheel drive with increased ground clearance (as seen here).

If you’re planning a real adventure in your camper, the 4x4 is a dream come true. There’s plenty to admire from Hymer, too – touch-operated LED lights, large soft-close drawers, a generous (90-litre) fridge and fabric-lined side walls for noise insulation are all standard. You can then enhance the interior with leather, a 19in TV, a lithium leisure battery, 6kW heating powered by either gas or diesel and even outdoor chairs and table with their own storage location. It’s a typically thorough Hymer approach that can be tailored to your needs.
