A revised Volkswagen Caddy BlueMotion has been revealed ahead of its debut at next month's Frankfurt motor show.

Claimed as the "most fuel-efficient Caddy ever", the updated van is powered by a tweaked version of the 1.6-litre four-cylinder turbo-diesel engine found in the current Caddy Maxi Van 250TDI.

Aided by a retuned engine control unit (ECU), engine stop-start technology, regenerative braking, and low rolling resistance tyres, the efficiency-focused Caddy is also helped by a 27mm reduction in ride height.

New wheel covers and ‘BlueMotion’ badging feature on the exterior, while the interior of passenger-based versions gain new seat upholstery and gloss black-accented air vents. Cruise control and hill hold assist are again standard.

Due to go on sale in Europe in the coming months, the Volkswagen Caddy BlueMotion is to be available exclusively as a short wheelbase model in panel van, kombi van and passenger van configurations priced from 17,720 euros ($26,200).

Volkswagen Australia public relations manager Kurt McGuiness told CarAdvice the model is under consideration for our market.

The 2013 Frankfurt motor show begins on September 10.
