TORRANCE, Calif.--(BUSINESS WIRE)--May 22, 2003

Enova Systems, Torrance, California (OTCBB:ENVA), has submitted its first quarter, ended March 31, 2003, results to the U.S. Securities and Exchange Commission, reporting that revenues increased to $1.34 million for the first three months -- a 42% increase over the comparable period in 2002. Revenues from production in the first quarter increased over 113% to approximately $1.0 million from $476,000 in 2002.

The Company's net sales of $1,340,000 for the first quarter ended March 31, 2003, increased $398,000, or 42%, from $941,000 during the same period in 2002. The net loss for the quarter of $743,000 was slightly higher then the loss of $704,000 in the first quarter of 2002. However, without one-time costs of revenue adjustments, the net loss from operations would be approximately $548,000, or approximately 22% lower.

Enova's revenue increases were the result of two primary factors -- new products and new customers worldwide. On the product side, Enova continues its strategy of developing leading edge components for the heavy-duty bus and truck sectors. In the first quarter of 2003, Enova began selling:

-- A high voltage (HV) Panther(TM) 120kW drive system (600Vdc -

900Vdc) -- a derivative of our current 120kW drive system with

double the power rating. Initially, Enova is delivering this

system to customers in Asia. This product line includes the

new Panther(TM) 120HV Control Electronics Unit and the

Panther(TM) HV120kW motor, as well as other high voltage

components such as the HV Safety Disconnect Unit.

-- An enhanced Panther 90kW drive system for dual rear wheel

motor configuration, expanding Enova's potential market

penetration with bus and delivery vehicle manufacturers. This

new system is capable of providing a mid-range, heavy-duty

solution at 180kW of peak power for current and prospective

customers.

-- An 18kW on-board fast charger system designed specifically

for heavy-duty applications. This new component, based on

Enova's proven charger technology, delivers the extra boost

for trucks' and buses' increased power requirements.

Additional information regarding these products and others may be found in Enova's Product Catalog on our website at www.enovasystems.com.

Carl D. Perry, CEO and President, stated: "Enova continues to seek new segments for its product line and augments its product base when profitable new applications arise. As the Company increases its market share in the heavy-duty bus and truck sector, we find new opportunities to enhance our components to fit the needs of our customer base. Each new system is analyzed for its broader appeal and applicability to a variety of customers and vehicle applications. We believe that this strategy of building on proven, successful products will enable Enova to capture greater market share this year and in the future."
