What Makes the GPT Different?
High Expectations
Drivers are held to a strict standard of racecraft and courtesy. Both are required to be successful here.
Schedule Flexibility
Thanks to the league's unique ELO-MMR rating system, drivers can be competitive without needing to make every race.
Dynamic Events
The GPT schedule is carefully crafted to challenge drivers in dynamic ways throughout the season, including Major championship events that represent the stiffest challenges but with greater rewards.
One Car
For series that offer multiple makes, drivers select a car and stick with it for the season, as they would in real life; no changing depending on the BoP of the week!
League Characteristics
Minimum Qualifications
Entry Requirements:
- Minimum iRating of 1,200
- Safety rating of B-3.0 or higher
Note: Drivers who are referred to the league by an existing member can be exempted from this requirement.
Because the GPT is a league for highly skilled drivers, most members have an iRating of over 3,000 and are accustomed to top split pace. The minimum requirements demonstrate that drivers possess sufficient experience to be likely to enjoy the competition the GPT offers.
In 2026 the GPT introduced a two-class structure, where drivers over 2,500 iRating or equivalent skill participate in the Platinum class, while drivers between 1,200 and 2,500 participate in the Gold class.
League Schedule
The league strives to create schedules that appeal to the largest number of members. Each season the schedule is reviewed to optimize participation.
Current Schedule:
- Main series events: Monday nights
- Sessions open: 8:00 PM Eastern
- Qualifying begins: 9:00 PM Eastern
- Season length: 7-12 races per season
Arrive and Drive Program: The GPT also offers an Arrive and Drive program that challenges drivers with surprise combinations of cars and tracks.
League Rating System
The GPT uses an innovative ELO-style ranking system developed by data scientists at Stanford. Similar to iRating, the system evaluates each driver according to their actual results and strength of field in previous events to rank drivers based on probability of success, with a bias towards more recent performances.
Overall Ranking, according to GPT Rating, is the measure by which drivers can qualify for the major events each year, and is the primary way of evaluating who the best drivers in the league are. The system is perpetual (it persists across seasons), just like iRating.
This system allows flexibility in participation while still ensuring a fair and competitive experience.
Season Points Championship
In May 2024, The Grand Prix Tour decided to also track a more traditional points-based championship for each calendar season, which rewards those drivers who consistently attend GPT events.
The total points pool is dynamic to the type of event, with three main Event Types:
Regular Events
Top 20 Score Points
Major Championships
Top 30 Score Points
50% more points!
Drop Race: Drivers will usually have two drop races per season.
