KFC is reigniting the chicken wars with a new sandwich to take on Popeyes and Chick-fil-A

• KFC is releasing a new crispy chicken sandwich in select cities.
• The sandwich is notably similar to competitors from Popeyes and Chick-fil-A, restarting the chicken sandwich wars.
• McDonald's and Burger King are also known to be working on competing sandwiches.

KFC is reigniting the $4 only one week into 2021 with the introduction of a new sandwich, available in nine US cities starting Thursday.

The fried chicken chain tested the new sandwich in Orlando, Florida last spring, and KFC said that sales were nearly double expectations, so "we knew we had a winner" chief marketing office Andrea Zahumensky said in a statement.

The sandwich, simply called the "KFC Chicken Sandwich," consists of a quarter-pound of white meat on a brioche bun with pickles and the option of spicy sauce or mayo. Beginning Thursday, it is available in Chicago, Kansas City, Louisville, Portland, St. Louis, Sacramento, San Francisco, Seattle, and Tulsa. By the end of February, customers can order the sandwich at any of the 4000 KFC locations across the US for $3.99.

KFC seemingly takes a shot at Chick-fil-A in its statement, saying that the sandwich "will be available seven days a week," while Chick-fil-A is famously closed on Sundays.

McDonald's plans to roll out $4 in late February, and $4 was spotted testing out a chicken sandwich in October. Wendy's also released a new "classic chicken sandwich" in October, replacing the older $4

Yum Brands, which owns KFC along with Taco Bell, Pizza Hut, and other chains, had a relatively good 2020 compared to other restaurant chains, with sales increasing $4 in Q3 compared to 2019. KFC sales declined slightly, which was offset by Taco Bell's gains in a year when the $4 and improved drive-thru performance.
