Google and Omnicom Group's Goodby, Silverstein & Partners, San Francisco, are working together on one of the agency's largest clients: GM's Saturn division.

The Google/Goodby, Silverstein project for Saturn begins Friday with a test that makes use of Google products and services, including clickable video, Google Earth satellite mapping and geo-targeting of users, writes the New York Times. "Google wants to prove it's an effective way to market. Saturn wants to sell Auras. And we want to show how we can tell good stories in a 21st-century way," Goodby, Silverstein co-chairman Rich Silverstein is quoted as saying.

The Aura campaign is intended to stimulate demand for Aura test-drives - the novel twist: dealerships will deliver the cars to consumers' homes. Google, seeking to expand beyond its core paid-search business, wants to call attention to more elaborate types of online advertising it offers, such as click-to-play video.

For the Saturn project, seemingly typical banner ads - when clicked by online users in cities that have Saturn dealerships - will produce a view of earth and zoom in on the nearest Saturn dealership, the doors of which fly open to show the general manager, who introduces a brief commercial.

Afterward, the manager offers users choices: e.g., viewing a 360-degree look at the car, printing a map with directions and inspecting the Auras engine.
