The signature burgers side by side
The Whopper carries 10 more calories than the Sonic Cheeseburger With Ketchup & Mayo. Calories use the upper bound where our two nutrition sources disagree.
Sonic is not really competing with Burger King on burgers. It is competing on format and on drinks. The drive-in model — park in a bay, order from a stall, eat in the car — is a different product from a drive-thru, and the drinks menu is the widest in American fast food.
On food the comparison is straightforward and mostly favours Burger King. On everything around the food, Sonic is playing a different game.

Who wins at what?
Burger King is better for
- A stronger and more consistent burger line, led by the Whopper
- Simpler, faster ordering through a conventional drive-thru
- Better price coverage across our tracked sources
Sonic Drive-In is better for
- A drinks and slush menu with combinations no burger chain approaches
- Tater tots, which Burger King does not sell in any form
- The drive-in format itself, which is the whole point of visiting
Tots, not fries
Sonic sells tater tots alongside fries and leans on them heavily. Burger King has no equivalent product. If tots are what you want, this comparison ends there — no amount of price or calorie data changes a menu that does not carry the item.
The drinks menu is the actual differentiator
Sonic markets an extremely large number of drink combinations across slushes, limeades and soft drinks. Burger King's drinks line, which this site tracks at 26 distinct drinks across 74 size variants, is conventional by comparison. For a customer who came for a drink, Sonic wins before the food is considered.
The format is the product
Sonic's drive-in model — park in a numbered bay, order from a stall, eat in the car — is not a slower drive-thru. It is a different way of eating, and for many customers it is the reason for the visit rather than an inconvenience to be tolerated.
Burger King has no equivalent format anywhere in its US estate. A comparison of burger calories cannot capture that, which is why the tables on this page are one input rather than the answer.
Discounted drink periods distort the price comparison
Sonic leans heavily on discounted drink periods, which shifts the effective cost of a visit in a way that published menu prices never capture. Burger King runs app-based promotions instead. Both are real savings, and neither appears in the figures above.
That is a general limitation of cross-chain price comparison, and it argues for treating a difference of a few cents in the table as noise rather than signal.
What our data actually covers for Sonic
Sonic has the most complete calorie coverage of any rival on this site, but far fewer of those items carry a tracked price. That imbalance is why this page leans on the calorie comparison and flags the missing prices rather than quietly filling them in with estimates.

Is Sonic a drive-thru or a drive-in?
Primarily a drive-in: you park in a numbered bay and order from a stall rather than queueing in a lane. Many locations also have a drive-thru, but the drive-in format is the distinctive part of the experience.
