What have we
learned since 2003
• In the case of commercial hybrid electric vehicles:
– Arrive later than planned, but they are here
– More Mild Hybrids than Heavy Hybrids
• In the case of military hybrid electric vehicles:
– Hybrid HMMWV Acquisition Initiative – killed
– RST-V Demo – still a demo
– FTTS / FCS still strong – but:
• Slower timeline than planned
• Under constant scrutiny for applicability and payoff
Key Drivers for
Vehicle Power
• Has to be rooted in a valid requirement
• Has to make business sense
• Has to be flexible
– Commercial viability
– Timeline flex
– Changing requirements
