ENOVA SYSTEMS REPORTS FIRST QUARTER RESULTS

        Enova Achieves Greater Sales and Introduces New Products in 2003

TORRANCE, CA May 22, 2003 - Enova Systems,  Torrance,  California (Symbol 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 than 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)  PantherTM  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 PantherTM 120HV Control  Electronics Unit and
     the PantherTM 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.

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."
