Trak map of Michelin Raceway Road Atlanta

Track Layout and Specifications

Road Atlanta is a permanent road course that blends high-speed straights with technical corners and elevation changes.

Track Specs:

  • Length: 2.54 miles (4.09 km)
  • Turns: 12
  • Surface: Asphalt
  • Elevation: Significant elevation changes throughout the lap

The track’s layout creates a constant flow, where each corner sets up the next. Drivers must think several turns ahead to maintain momentum.

Signature Sections and Notorious Turns

Road Atlanta’s reputation comes from several key sections that challenge even the most experienced drivers.

Turn 1

A fast, downhill right-hander immediately after the start/finish straight.

  • Blind entry at high speed
  • Requires full commitment
  • Minimal margin for error

Drivers crest the hill and turn in without full visibility, making it one of the most intimidating corners in North America.

The Esses (Turns 3–5)

A high-speed sequence that defines the rhythm of the track.

  • Fast left-right transitions
  • Requires precise steering inputs
  • Critical for maintaining lap time

Mistakes here disrupt momentum through multiple sections.

Back Straight

One of the fastest sections of the circuit.

  • Allows top speeds for prototypes
  • Key overtaking zone
  • Leads into heavy braking

This straight highlights the performance differences between classes.

Turn 10A and 10B (The Chicane)

A tight braking zone at the end of the back straight.

  • Heavy braking from high speed
  • Prime overtaking opportunity
  • High risk of mistakes

Drivers must slow the car dramatically before navigating the chicane.

Turn 12

The final corner leading onto the front straight.

  • Fast, sweeping right-hander
  • Requires precise throttle control
  • Critical for lap time

A strong exit here sets up overtaking opportunities into Turn 1.

Why Road Atlanta Is Infamous

Road Atlanta has earned its reputation through a combination of speed, elevation, and unforgiving design.

1. Elevation Changes

The track rises and falls dramatically.

  • Blind crests challenge visibility
  • Downhill braking zones test control
  • Constant weight transfer affects grip

Drivers must adapt continuously throughout the lap.

2. High-Speed Commitment

Many corners require full confidence.

  • Turn 1 demands bravery
  • The Esses reward precision
  • Turn 12 tests throttle control

Hesitation often results in lost time or errors.

3. Limited Runoff Areas

Unlike modern circuits, Road Atlanta offers little room for recovery.

  • Grass and barriers are close to the racing line
  • Mistakes are punished immediately
  • Precision is essential

4. Multi-Class Traffic at Speed

With multiple classes on track, traffic becomes a major factor.

  • Prototypes approach GT cars at high speeds
  • Timing overtakes is critical
  • Drivers must maintain awareness

This creates constant decision-making throughout the race.

Race Classes Competing

Road Atlanta features a full IMSA® field, delivering some of the most dynamic multi-class racing in the world.

Current Classes:

  • GTP (Grand Touring Prototype) The fastest cars, featuring hybrid systems and advanced aerodynamics.

  • LMP2 (Le Mans Prototype 2) Highly competitive prototype class with strong performance.

  • GTD Pro (Grand Touring Daytona Pro) Professional GT entries from manufacturers like Porsche®, Corvette, and Ferrari®.

  • GTD (Grand Touring Daytona) Mixed driver class featuring both professionals and amateurs.

This multi-class format ensures constant interaction across the field.

Race Duration and Event Schedule

Strategy and Race Dynamics

Endurance racing at Road Atlanta requires careful planning.

Key Factors:

  • Tire Management: High-speed corners increase wear
  • Fuel Strategy: Efficient pit stops are critical
  • Driver Rotation: Multiple drivers share responsibilities

Teams must balance speed with long-term strategy.

A Unique Atmosphere

Road Atlanta offers a distinct fan experience.

  • Natural viewing areas across the circuit

As the race transitions into night, the atmosphere changes dramatically, adding another layer of challenge.

Team Strategy

Michelin Raceway Road Atlanta stands as one of the most complete circuits in North American racing.

It is defined by:

  • Speed
