Test Driver Ratings & Comments

Acceleration commentsThe Mariner's undramatic acceleration isn't anything to write home about. There's no technique required to equal these numbers. Power braking a hybrid hardly seems appropriate and doesn't make it any quicker anyway.
Braking ratingAverage
Braking commentsThe Mariner's brake pedal is a quandary. At first it feels like there's an almost magnetic resistance to the pedal, which always feels like it will go to the floor with enough effort. It takes some time to get used to during normal driving and never really inspires confidence. But once adjusted, its effectiveness is OK. During brake testing the pedal actually reaches a hard engagement point somewhere just above the floor, which is the ABS-activation point. Overall, it's weird, but it works.
Handling ratingPoor
Handling commentsThe Mariner Hybrid lacks roll stiffness, grip and high-speed suspension damping, which makes it laughably sloppy during instrumented testing. It never does anything really dangerous, but it's clearly not designed for limit driving. Its 3,714-pound curb weight doesn't help matters any.
