"Five Down. Five to Go": The Mechanics of the NASCAR Postseason

When the official NASCAR social feed drops "Five down. Five to go. 👀💰", the stock car racing world reaches its most pivotal strategic inflection point. In the modern NASCAR Cup Series playoff system, 16 drivers qualify for a 10-race knockout tournament split into four distinct rounds:

Round of 16 (Races 1 – 3): Darlington, Kansas, Bristol. Field narrows from 16 to 12 drivers.
Round of 12 (Races 4 – 6): Texas / Kansas, Talladega Superspeedway, Charlotte Motor Speedway ROVAL. Field cuts from 12 to 8 drivers.
Round of 8 (Races 7 – 9): Las Vegas, Homestead-Miami, Martinsville. Field cuts from 8 to the Championship 4.
Championship 4 (Race 10): Phoenix Raceway. Highest finisher among the 4 finalists claims the Bill France Cup.

The "Five Down" Milestone Race 5 represents the exact mathematical midpoint of the 10-race postseason. At this stage, drivers have navigated the Round of 16 elimination and the opening two races of the Round of 12. Race 6—often hosted at the chaotic Charlotte ROVAL or Talladega—is the immediate elimination cut race where four drivers' championship hopes evaporate.

How NASCAR Playoff Stage Points & Cutlines Function

A driver's position relative to the "Cutline" is determined by two simultaneous pathways: Automatic Advancement by Winning and Net Points Accumulation.

Each standard race awards points in three distinct intervals:

Stage 1: 1st place earns 10 regular points plus 1 Playoff Point; 2nd earns 9; descending down to 10th place earning 1 point.
Stage 2: Identical distribution to Stage 1 (10 down to 1 point, with 1 Playoff Point for the stage winner).
Race Finish: The race winner earns 40 points plus 5 permanent Playoff Points. Second place receives 35 points, 3rd gets 34, down to 36th–40th place receiving 1 single point.

Because up to 20 stage points are awarded prior to the final checkered flag, a driver running 15th who maximized stage points can often outscore a driver who finishes 8th with zero stage points. This creates intense tactical decisions: whether to pit before stage ends for track position, or stay out to bank guaranteed stage points.

The "Win-and-You're-In" Bubble Upset

If a driver entering the elimination race ranked 12th (e.g. 30 points below the cutline) manages to win the race, they steal an automatic transfer spot. As simulated in our Underdog Win Steal preset, this immediately pushes the driver ranked 8th onto the wrong side of the cutline, turning what looked like a comfortable points cushion into instant elimination.

Postseason FAQs

What does "Five down, five to go" mean?

It refers to the completion of the first five races of the 10-race NASCAR Cup Series Playoffs. At this halfway juncture, five races remain: Race 6 (the Round of 12 elimination cutoff), Races 7–9 (Round of 8), and Race 10 (the Phoenix Championship 4 finale).

Do playoff points carry over into the next round?

Yes. Accumulated Playoff Points (earned via stage wins, regular season wins, and regular-season championship placement) carry over and are added to the driver's reset baseline in the Round of 12 and Round of 8. However, they are zeroed out for the Championship 4 at Phoenix, where all four finalists start with an equal 5,000 points.

What is the tiebreaker rule at the cutline?

If two drivers are tied on points for the final advancing spot at the end of an elimination round, the tiebreaker is awarded to the driver with the best single finish in that current three-race round.

How many drivers advance from each playoff round?

16 drivers start the playoffs. Four are cut in the Round of 16 (leaving 12). Four more are cut in the Round of 12 (leaving 8). Four are cut in the Round of 8, leaving 4 finalists who compete directly for the championship title in the season finale.
