• Idle-free driving can improve fuel economy by approximately 10%.
  An even greater energy conservation effect is expected in urban areas, where car stopping frequency is high.
• Partial subsidy for the purchase of cars equipped with the gidling-stoph system was introduced in FY2003.
• Promotional campaigns for gidling-stoph systems are held in the form of PR events, etc.

Result of the driving experiments by "idling-stop" cars	PR activities
Results of "The Idling-Stop 2002 Caravan Throughout Japan" Nationwide (3719km)...5.8% on average Or 13.4% in city areas [Stop & “idling-stop” implementation time ratio in urban area]	An event for "idling-stop-at-stoplight" experiments is scheduled for October 2005 Idling-free promotional event (Osaka)

• In total travel, the ratio of stopped time is 24% and idling stop is implemented in 52% of the stopped time.
  
• In urban centers, the ratio of stopped time increases to 48% and between such urban centers, the ratio of stopped time decreases to 14%.
  
• Idling stop is implemented in about half of the stopped time.

Reduction of fuel consumption by:
5.8% in total travel
13.4% in urban centers
