Highway, City & Towing
My mixed city/highway was running about 15mpg for the first 500 miles. I was hoping it would improve with time and it apparently has.
On my first road trip of 500+ miles I averaged 26mpg which was great for me since that was was great improvement over my Toyota Sienna and I often travel at 5-10 over the speed limit.
Towing however, is another story. My trailer is near the 3500# limit and it has a frontal area of about 80 sq ft. My 1300 mile road trip over the Sierra mountains to Death Valley and back averaged 14mpg. That might not sound good but my 2008 Toyota Sienna did less than 10mpg under the same circumstances.
Overall I was quite satisfied with the tow performance (factory tow) the engine has good power and the transmission does it's job. With the trailer I have been setting the ACC to 62 mph (55 mph limit in CA) and following the traffic. I suspect the Pacifica is optimized for highway travel with light loads and if I demanded better towing mileage I would be advised to buy a diesel truck.
At this point with about 3000 miles it looks like I will settle out about 23 mpg in mixed driving conditions.
