Very poor fuel economy
By R. Cardiff on
2007 Buick Lucerne CXL V6 4dr Sedan (3.8L 6cyl 4A)
As a long time Park Ave owner, I was spoiled. This Lucerne is no Park Ave! Window sticker showed 28 mpg highway and I have not gotten close to that, 26.3 is best I have gotten and mostly 24 to 25 mpg. On the '04 Park Ave (on the same trips) I would get 31 to 32 mpg. Same engine they say but Buick says they changed the gear ratio and I ask why and get no answer. I find it difficult to get in and out of and the head room is poor. My next car will not be a Buick Lucerne, unless they improve on the fuel economy.
It rides great and is quiet.
Improve the fuel economy and be honest about why this '07 CXL is so low in mpg.
