What's New for 2005
"The base engine is enhanced this year with electronic throttle control, and a new four-speed automatic transmission is available. An air filtration system is now standard on all Foresters. Also new this year is the 2.5 XS L.L. Bean Edition, which includes a myriad of interior and exterior trim enhancements, rugged cargo area trim and a self-leveling rear suspension."
I cannot see anything other than what is listed as a reason for improvement in fuel economy of the 2005 model vs 2004.
Are you saying that the gear ratios have changed and curb weight reduced? And the 2005 model is more "slippery" than the 2004?
Just asking, as I really don't know.
Thanks.
