Full review

One of the major themes of Adria’s new 2020-season range is the introduction of a number of (just) sub-seven-metre motorhomes, with the ‘600’ suffix. These include the latest, more compact A-class Sonic seen here.

This motorhome stands apart from the rest of the Sonic range not only in size but spec level. Adrias usually come in Axess, Plus and Supreme trim, but the larger A-classes are, appropriate to their flagship status, only available as Supremes. Here, though, is an Axess-spec Sonic, which brings the price down to a level that opens up a wider potential audience, including those who perhaps thought that an A-class was out of their reach.

The final part of the model designation – the SL suffix – indicates a single-beds-over-garage floorplan (there are no other Sonic layouts at this size/price level in the UK). In common with others of its ilk, the beds are mounted high, with access via a couple of steps. Bed lengths are very generous, though, at 1.90m on the nearside and a super-sized 2.01m on the offside.

There are also ratcheted supports to raise the head of each bed, so you can comfortably sit up without banging your head on the lockers above. USB ports and reading lights are sited under the cupboards and there’s a small roof vent, as well as the typical central infill cushion between the beds (measuring 1.56m long here).

A concertina screen (rather than a proper door) provides privacy for the rear bedroom, which could be important as there’s also a drop-down double in the cab.

Up front, the Aguti captain’s chairs swivel to make a very comfortable lounge for two or three people, or which can accommodate up to five at a push. It feels spacious, thanks to the A-class cab, while there are pillow-style backrest cushions along the narrow side ection of the L-settee. However, the unusual feature is a flip-up jump seat by the door – which isn’t blocked because this is an extra-wide entrance.

The example photographed was to continental-spec, so lacking the oven/grill of UK-bound models – some of the huge drawer space here will be lost to accommodate that. You’ll still appreciate the high-quality soft-close mechanisms, though, and the push-to-open operation of the stylish concave top cupboards. The L-shaped sink/hob unit frees up useful worktop space and there’s a tall 142-litre fridge/freezer with automatic energy selection alongside. A TV bracket is fitted in the cupboard over the fridge but you won’t be able to watch your favourite show if the chef is hard at work.

There’s more successful space utilisation in the washroom, where an XL-sized shower cubicle has two diagonally opposing drains. Behind the swivel toilet is an opening window but the washbasin is hidden behind a mirror – until it folds down above the toilet.

Of course, one of the key reasons to buy here will be the garage with its generous 1.18m maximum internal headroom. Adria has focused attention on upgrading its garages across the range this year and here you’ll find 12V, 230V and USB sockets, as well as fixed tie-down points, LED strip lights on the back wall and drains in the floor. The Sonic also has nearly 500kg of payload – much more if you uprate the chassis.

Here, then, is an A-class that can be realistically used in 3,500kg form (unlike so many rivals) and also seems well-built and well-priced. It could be an ideal motorhome for your first venture into A-class ownership.
