System designed to interface with all Worldwide EV and HEV technologies, including Natural Gas

May 23, 2012

TORRANCE, CA, May 23, 2012 - Enova (NYSEAMEX: ENAand AIM: ENVand ENVS), a leading developer of proprietary hybrid electric and all-electric drive systems and drive system components for the emerging green commercial vehicle market, announced today it has begun development of its next generation system, code named ACUMEN™. With the completion of its OMNI™ drive system, the Company is now looking to further optimize its ability to interface with all worldwide EV and HEVsystems, including those powered by natural gas.

Enova previously announced its new OMNI™ drive system which combines the 170kW OMNI™ Inverter with a new 10kW OMNI™ Charger with an entire range of AC Induction and Permanent Magnet motors. The OMNI™, now available, is expected to be a leading technology for the industry for years to come.

While OMNI™ was developed in house, with the ACUMEN™ system, Enova looks to evaluate and utilize technologies that are emerging worldwide. The Company is actively searching for the latest technologies to maintain OEMproven leadership and offer competitive advantages that make real business sense for vehicle manufacturers and fleet operators alike. The ACUMEN™ components are intended to feature a significantly smaller package, improved efficiencies and reduced weight, while achieving close to double the power density of older generation designs and competitors products. The new ACUMEN™-Series system will be power-source agnostic, including natural gas, and will offer increased application flexibility and ease of integration. With all digital control and plug-and-play connectivity, Enova intends to design ACUMEN™ to be compatible with all vehicle drive systems and motors so that it can be configured for HEV, PHEVand EV applications.

As a result of Enova's initiative to develop ACUMEN™ using the industry's most advanced technologies, the Company recently hosted EV France (www.ubifrance.com), a consortium of top French automotive manufacturers including Renault, Peugeot ad Volvo Truck, suppliers, clusters and research laboratories working in the field of hybrid and hybrid electric vehicles, advanced batteries and infrastructure support. Enova met with EV France representatives at its headquarters in Torrance, California to forge research, commercial and partnership opportunities. The group was able to view Enova's technology as well as participate in an on-site ride and drive of Enova's range of drive systems, including the new OMNITMdrive system. France has the second largest auto market in the EU with over 2.2 Million cars sold in 2011. More EVs were sold in France in 2011 than in any other country in Europe. Germany has the largest automotive market in Europe and after France, the second largest EV market. Enova has also met with a similar group from Germany and will continue to mature these opportunities in its expansion into the European markets. In the UK, the third largest EU EV market, Enova already supplies both Smith Electric Vehicles as well as Optare, who just announced the launch of the Solo SR EV's trials in Poundbury. http://www.optare.com/pr_18_05_12.htm

It is believed by Enova that recent reluctance in the industry to deploy large volumes of EVs validates the need for groups to compliment each other's technologies to drive the industry. Mike Staran, Enova's President and CEOsaid "The industry is at a position where we are trying to get enough critical mass to move forward, yet there remains extreme caution and a lack of urgency in regards to larger volume EV deployments. Enova's aggressive approach towards forging worldwide partnerships should further strengthen our ability to control distribution channels and move past the caution that currently exists."
