Adria is perhaps best known for its low-profiles and van conversions, both of which are a common sight on UK roads and campsites. But the manufacturer also makes a fine A-class, in the shape of the Sonic, which has been part of the Slovenian manufacturer’s portfolio since 2010. Also available in Axess and Plus trim levels, Adria waited until last year’s Caravan Salon in Düsseldorf to unveil the revised Sonic models, the island bed I 710 SBC and twin single beds I 710 SL, on test here. Where better to line up against all those highly regarded German A-class motorhomes? 

Indeed, the plucky Slovenian marque – which exports 98 per cent of its total production of motorhomes, caravans and holiday homes – is as accomplished as the German brands when it comes to selling itself in foreign markets. At Adria’s birthday celebrations earlier this year to mark its half-century of leisure-vehicle production, the company laid claim to be the biggest single-branded motorhome manufacturer in Europe.
