As well as replicating the edition, the Flash-based format also hosts videos and enables users to book test drives. Future issues of the electronic magazine will use bespoke content filmed by River's new digital division.
The department recently launched electronic projects for American Golf and Co-op Travel Group plans to roll out digital magazines for more of River's clients.
Advertisers will be encouraged to supply rich media copy, including Flash animation and TV adverts, to fit into the magazine's look and feel and encourage better response.
