The V-8 is thirsty for city driving. The extra power would be nice for highway & mountain driving, though. see full Mercury Grand Marquis review

We got the V6 for the supposed fuel-economy benefits. The car rarely breaks 20mpg (with a one-time high of 23), and last in-town average is about 14 mpg. see full Cadillac SRX review

Mileage is acceptable but nothing more. Around 20 MPG on the highway and 15-16 around town. see full Cadillac SRX review
