RENAULT has failed to make a big impression on the Australian market and is using a diesel strategy to make incremental gains in its market share. The latest vehicle to get a diesel engine is the Scenic mini-people-mover, which seats five people in great comfort and provides them with plenty of useful and innovative interior features. The common-rail turbo-diesel itself is both more potent and economical, but is let down by the sluggish four-speed auto. Nevertheless, the Scenic dCi is a packaging marvel and deserves to be considered by Australian families concerned about the environment and their own back pockets.
