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.

Price comparisons use the tracked RANGES, not their midpoints. Where two ranges overlap the table says so rather than naming a winner, because at some pairs of restaurants either chain can be the cheaper one. A direction is claimed only where the ranges do not overlap at all, and the figure shown is then the gap between the nearest bounds, which is a minimum rather than an estimate. Calories use the upper bound where our sources disagree, so nothing is understated. See how we source prices and calories.
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.
Burger King vs Sonic Drive-In FAQs
Does Burger King sell tater tots?
No. Burger King sells French fries and onion rings; it does not carry tater tots in the US. Sonic sells tots in three sizes and treats them as a core side.
Is Sonic more expensive than Burger King?
Our price coverage for Sonic is thinner than for Burger King, so the table below shows fewer priced rows. Where both are tracked the comparison is shown; where a price is missing it is marked as not tracked rather than estimated.
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.
Does Burger King have a drinks menu comparable to Sonic's?
No. Sonic markets an extremely large number of drink combinations across slushes and limeades. Burger King's drinks line is conventional by comparison, at 26 distinct drinks across 74 size variants in our dataset.
What is Sonic Happy Hour, and does Burger King have anything like it?
Sonic runs a long-standing afternoon window with drinks at a reduced price, and it is a core part of why people go. Burger King has no scheduled equivalent; its discounting runs through app offers instead, which are personalised and appear without a fixed timetable. Our <a href="/burger-king-coupons">coupons page</a> explains how those work and why a printed coupon list would be out of date almost immediately.
Tots or fries: how do the sides compare?
Tater tots are Sonic’s signature side and Burger King does not sell them at all, so this is a straight availability question rather than a quality one. Burger King counters with onion rings, which Sonic also carries. Our <a href="/burger-king-sides-menu">sides page</a> lists every Burger King side with a price range and calorie figure.
Which is cheaper, Burger King or Sonic?
Sonic tends to look cheaper on drinks, especially during its afternoon window, and closer to level on food. Because both chains are franchised and price independently, a national verdict is less useful than checking your own two restaurants. The full tracked Burger King range is on the <a href="/burger-king-prices-by-location">prices by location page</a>.
How do the burgers compare?
Burger King has the stronger burger case: flame-grilling is a real process difference and the Whopper is a more substantial sandwich than Sonic’s equivalents. Sonic’s burgers are competent rather than the reason anyone drives there. The drinks and the format are what pull Sonic’s customers in, which is unusual among burger chains.
Does Sonic serve breakfast for longer?
Sonic serves its breakfast items all day, which Burger King does not. Burger King’s morning menu stops at roughly 10:30 am and the changeover is firm. If you are comparing the two for a late-morning or afternoon breakfast order, that difference decides it outright. See our <a href="/burger-king-breakfast-menu">breakfast page</a> for the Burger King side and its cut-off.
Why is Sonic’s ice talked about so much?
Sonic uses small pellet ice, which chills a drink faster and is widely preferred for chewing. It sounds trivial and it is genuinely part of why customers pick Sonic for a drinks run. Burger King uses conventional ice. It is a small thing that a comparison page should not pretend is not a factor, because for a certain customer it is the whole factor.
Which chain has wider coverage?
Burger King is more evenly national. Sonic is denser in the South and Midwest and thinner in the Northeast, so for many readers the practical choice is made by which one is nearby rather than by anything on the menu. Where both are available, the drive-in format is a more meaningful difference than any single item.
