Like Old Mechanic says, that sounds wrong. Small cars with CVTs are usually doing 2.5 - 3k at 60 mph.

CVTs are just like any other transmission... the final ratio is what decides your cruising rpms in top gear. Bigger engined cars with CVTs usually have lower cruising rpms than smaller ones, to take advantage of the extra torque.

Honda's CVTs have excellent economy, just as good as their manuals or better in the real world, but the clutch packs are problematic over the long term.
