i swear ford designed it like that. i can even put a skinny or extra wide bottle or can in mine, and adjust the passenger seat bolster to hold it more firmly or more loosely.
that cupholder works wonders. and for water bottles, or gatorade bottles,or any 20 oz bottles, try shoving it down inbetween the pass seat belt buckle and the console. even more perfect.
im kinda anal about spilling stuff though. i spilled a red bull in mine and i pulled the carpet and shampood / powerwashed it. lol.
