The Ford Expedition, the Cadillac Escalade ESV, the Chevrolet Suburban, and the Toyota Sequoia. All four have tanks that can hold more than 26 gallons.

The Expedition has the biggest tank on the market, at 33.5 gallons. So if you wanted to fill up, at the current average gas price you'd drop $127.

If the gas price makes it up to $4.50 (which it really could this summer) it'll also cost at least $100 to fill up the Jeep Grand Cherokee, Audi A8, Mercedes-Benz S550, and the BMW X5.

On the other end of things, for a fill-up on a Toyota Prius to hit $100, gas would have to hit $8.40 a gallon.  The Prius only has an 11.9-gallon tank.

For a Honda Civic fill-up to cost $100, gas would have to hit $7.57.
