Abhishek Sharma scored 63 off of 23 balls, Heinrich Klaasen scored 80, not out of 34, and opener Travis Head scored 62 off of 24 balls.
They enabled the Sunrisers to surpass the previous IPL record of 263-5 set by Royal Challengers Bangalore in 2013.
Mumbai attempted to pursue the highest-scoring Twenty20 match in history with some reasonable success, but ultimately finished on 246-5.
In addition, the Sunrisers’ score was the highest in a T20 franchise tournament and the fourth-highest of any men’s T20.
Nepal currently holds the men’s T20 record after defeating Mongolia 314-3 in the previous season. In 2019, Afghanistan defeated Ireland 278-3, and the Czech Republic defeated Hungary 278-4.
In the Australian Big Bash in 2022, the Melbourne Stars defeated the Hobart Hurricanes 273-2 to set the previous record in a franchise competition.
After Mayank Agarwal was out for eleven, Australia international Head was dropped for five and quickly raced to an eighteen-ball fifty while putting up 68 in 23 balls with Abhishek.
