Quite accurate at all accounts except for the comment on the bumpy ride of the CX5. I certainly do not think the CX5 is bumpy, even when compared to the Accord. As a matter of fact, the Accord may feel slightly bouncier due to the soft suspension vs. the stiffer CX5 suspension. The CX5 is one of the most stable SUVs I have experienced which rides like a sedan.

One example of an SUV which has a bumpy ride is the Mitsubishi Pajero Sport which rocks like a boat with all the undulations on the highway.

Comfort and spaciousness, it is true the Accord is better due to the softer leather seats and larger space especially the leg room at the rear.

Bouncy is quite similar to bumpy. Though bumpy is usually used to show that the ride is not comfortable.

Although stiffer suspensions will generally produce a bumpier ride when compared to less stiffer (ie. softer) suspensions, it is just a generalisation. If probing into detail, it will depend on the extent of stiffness of the suspension. A suspension that is too stiff will of course be bumpier than one that is moderately stiff. However, moderately stiff suspension will be less bumpier than a soft suspension. A soft suspension will be bouncier (the term bouncier can be used to describe the spring of the suspension) than a stiffer suspension. If the vehicle with a soft suspension is traveling on a road with a lot of bumps, unevenness or undulations, it will bounce up and down more than a vehicle with a stiffer suspension due to the bouncier spring.

Re. which vehicle produces a bumpier ride, the CX-5 with stiffer suspension or the Accord with softer suspension. The definition of "bumpy" is "sudden up and down movements". With the CX5, although the suspension is stiffer(than the Accord), the movements with undulations on the roads although minimal, does not translate to sharp knocks. The vertical movement of the vehicle with the unevenness of the road is rather linear. With the Accord, due to the softer suspension, the vertical movement is more pronounced as the vehicle moves up and down quite a bit more than the CX5 due to the soft comfort-tuned suspension that is on bouncier springs.

It's a fine line to tread to objectively define or categorise on the degree of "bumpiness" of a vehicle in comparison though I would think a bumpy vehicle will bounce more than one that is less bumpy. A bouncy/bumpy vehicle can still be comfortable, in fact more comfortable than a vehicle that is less bumpy. And vice versa. However, a vehicle that is too bouncy (soft suspension) can be less comfortable than a vehicle with a stiffer suspension if it the vertical movements are too much, causing a headache.

In summary, it is subjective whether a vehicle with stiffer or softer suspension is more comfortable, depending on individual's preferences, but the degree of bumpiness(or bounciness) of a vehicle can be objectively defined.
