A compact, easy to drive horsebox, with a gross maximum weight of 3,500kg, meaning it can be driven by anyone with a standard car licence.

The Sonic is powered by a powerful HDI diesel engine which complies with the latest emission standards, giving effortless performance and outstanding economy.

The Sonic has the added benefit of a tack and changing area that is totally separate from the horses. This incorporates two saddle racks, two bridle racks and two coat hooks. There is also additional storage over the cab.
