IRVINE, Calif., June 20 /PRNewswire-FirstCall/ -- Quantum Fuel Systems Technologies Worldwide, Inc. (Nasdaq: QTWW), a leader in the development and production of advanced propulsion systems, energy storage technologies, and alternative fuel vehicles, is set to join the Russell 3000 Index and the Russell Global Index when Russell Investments reconstitutes its indexes on June 27, 2008, according to a preliminary list of additions posted June 13, 2008 on http://www.russell.com.

Annual reconstitution of Russell's U.S. indices captures the 4,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization. Membership in the Russell 3000, which remains in place for one year, means automatic inclusion in the large-cap Russell 1000(R) Index or small-cap Russell 2000(R) Index as well as the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes.

Alan P. Niedzwiecki, President and CEO of Quantum, commented: 'Being included in the Russell 3000 Index is a great opportunity to increase our visibility within the investment community and supports our viability as a premier provider of advanced energy technologies and solutions.' He went on to say, 'We believe we are on the leading edge of a new automotive age as we move to the electrification of the automobile. As worldwide demand and other pressures on oil, such as an over reliance by developing countries, continues to rise, and as people seek cleaner and more renewable power sources, demand for our hybrid propulsion systems and other alternatives such as Quantum's fuel cell systems technology, will continue to increase.'

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. An industry-leading $4.4 trillion in assets currently are benchmarked to them. These investment tools originated from Russell's multi-manager investment business in the early 1980s when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers.

The Russell 3000 also serves as the U.S. component to the Russell Global Index, which Russell launched last year.
