Overview

The 2015 Chase for the Sprint Cup was the playoff system used by NASCAR to determine its premier series champion. It marked the 11th season of the post-season format, which evolved significantly from its original 2004 version to include elimination-style rounds.

Contested over 10 races, the Chase began on October 17 at Chicagoland Speedway and concluded on November 22 at Homestead-Miami Speedway. A total of 16 drivers qualified based on wins and points, with eliminations after each three-race round narrowing the field to four title contenders.

Kyle Busch won the 2015 Sprint Cup title, becoming the first driver to claim the championship after missing races due to injury—specifically, he missed the first 11 races after a February crash at Daytona.
The Chase Grid reset standings after the regular season, awarding 2,000 points plus 3 bonus points per win to each playoff-eligible driver.
Drivers were eliminated after the Round of 16, Round of 12, and Round of 8, leaving only four eligible to win the title at Homestead.
Jimmie Johnson won the final race at Homestead, but Kyle Busch finished third and secured the championship by 78 points over Martin Truex Jr.
The 2015 format introduced a win-and-in rule, meaning any race win during the Chase automatically advanced a driver to the next round, regardless of points.

How It Works

The 2015 Chase used a tiered elimination structure designed to increase drama and reward performance under pressure. Each round tested consistency, strategy, and resilience, with only the top performers advancing.

Win-and-In Rule: A victory in any Chase race guaranteed advancement to the next round. This incentivized aggressive racing and reduced reliance on points.
Round of 16: The first round included 16 drivers. After three races, the bottom four in points were eliminated, leaving 12.
Round of 12: The second round narrowed the field to eight. Drivers reset to equal points, with wins or highest finishes determining survival.
Round of 8: The third round culled the field to four. Only those four could win the title at Homestead, regardless of their season-long consistency.
Championship 4: The final four drivers entered Homestead with identical points. The highest finisher among them won the title, making the race outcome decisive.
Points Reset: After each round, remaining drivers had their points reset with incremental bonuses for wins and stage finishes, keeping competition tight.
