Euro RSCG London's new global TV and cinema campaign to promote the Peugeot 307 HDi focuses on the "smoothness" of its diesel engine. The ad opens with a little girl carefully painting at what looks like a table. She dips her brush in a glass of water beside her and meticulously colours in the picture, before resting her paintbrush in her mouth. The camera then reveals the girl is sitting in the back seat of the Peugeot 307 HDi. The commercial ends with the line: "the new smoother 307 HDi: the surprising diesel."
