As a new member i would like to say you guys have a great forum. I have definitely decided to purchase a new 2010 Fusion SEL but am unsure as to whether it be a 2.5 I4 or 3.0 V6. Aside from the obvious differences of fuel savings vs extra power, can anyone comment on real world experiences between the two powertrains? I test drove both and found the 2.5 more than sufficient with acceleration but noisier than the 3.0. The 3.0 seemed silky smooth and very quiet with awesome power. Also of concern is fuel economy, as a highway commuter in rush hour traffic i'm aware of the posted mileage ratings but these are usually better than real life. Also, I would like to compare the predicted durability ie. the I4 working harder to produce same results as the V6. Sorry for the long winded post but would appreciate any input.
