Migration to 4-Cylinder Engines Continues with 2010-MY Ordering
The ongoing volatility of gasoline prices has prompted a growing number of fleets to transition to four-cylinder engines.

Early indications are that the migration to four-cylinder engines will continue with 2010-MY ordering. We have already seen glimpses of this trend in the 2010 RFPs submitted to major OEMs.
