Zipcar, World's Leading Car Sharing Service, Races Ahead with New Reservation Technology and Fleet Optimization System

Builds patent-pending technology to create unprecedented solution for managing dynamic network of vehicles and users

CAMBRIDGE, MA, (March 12, 2007) — Zipcar, the world's largest car sharing service, today unveiled the redesign of its web-reservation and patent-pending "Z3D Knowledge Center." As the most ambitious and significant upgrades in the company's history, these enhancements allow Zipcar to strengthen its award-winning membership experience while preparing to scale its service in existing and new markets.

The web-reservation redesign follows Zipcar's "member first" philosophy, and was completed based on member feedback, including 30,000 survey responses, one-on-one meetings, and usability testing at various stages of development. The result is a completely enhanced system that allows members to find and reserve vehicles two to five times faster than the previous version. Members will experience:

• Simple Usability: Targeted search results with one-click reservation option that includes a single reservation confirmation review page featuring vehicle photo, reservation time, reservation cost, location maps, instructions, and applicable policies.
• Intuitive Design: Unique use of Ajax technology allows members real-time interaction with ever-changing vehicle availability resulting in click and drag functionality for changing reservations "thermometer."
• Quick Reservations: Available cars and the estimated costs of a particular reservation are viewable in a single browser window, allowing users to quickly scan available vehicle choices by location, time and price.

The new reservation system is supported by Zipcar's "Z3D Knowledge Center" that hosts all data in real time and synchronizes it with data collected from each end point: interactive telephone systems, vehicles, member service agents, regional employees, and the new web-reservation system. The Knowledge Center then uses patent-pending, unique caching to push the synchronized data out to each end point in the most efficient manner. This upgrade enables Zipcar to better manage, monitor, and maintain its vehicle fleet as well as plan and optimize fleet size and future vehicle locations. Other benefits include:

• Support Global Expansion: "Z3D Knowledge Center" is capable of delivering a world-class online experience for up to one-million Zipcar members and supporting tens of thousands of vehicles, globally.
• Increase Self-Service: Targeted search results are expected to lower reservation abandonment rate and reduce reservation assistance calls.
• Improve fleet yield management: By applying proprietary business rules to the synchronized data, the Z3D knowledge center provides Zipcar with location-specific vehicle deployment needs.

"With this launch, we are now prepared to support tens of thousands of cars and hundreds of thousands of members throughout the world by presenting them with an efficient and intuitive reservation and service experience," said Scott Griffith, CEO of Zipcar, Inc. "The upgrades to our Knowledge Center and backend systems are based on the experience of processing 1.5 million reservations, and we are confident that they will allow us to intelligently manage our growing fleet while providing an easier and faster user experience for our members."
