Polyphony Digital dropped a pair of Online Time Trials that demand absolute commitment, high aero precision, and zero hesitation on the brakes. Both events offer up to 2,000,000 Credits for Gold, running a two-week window from September 24 through October 8.
If you plan to bank 4M credits without binning your rig into the barriers, here is the technical breakdown, track nuances, and setup advice you need before turning a lap.

Challenge 1: Road Atlanta in Modern Gr.1 Hypercars
Wringing out top-tier LMDh machinery—the Porsche 963 and the BMW M Hybrid V8—around Road Atlanta on Racing Mediums requires balancing high downforce against chassis instability.
The Danger Zones
- The Esses (Turns 2–4): Downhill, blind compression. The aero is working overtime here, but because you are running Medium rubber rather than Softs, any sudden mid-corner weight transfer will snap the rear. Smooth steering inputs and minimal micro-corrections are required.
- Turn 10A Braking: You are approaching at over 200 mph before shedding speed into a tight downhill chicane. Consistent threshold braking is everything; missing your brake release by 5 meters compromises the entire run onto the bridge.
- Turn 12 Commitment: A blind plunge under the bridge toward the main straight. You have to commit to throttle before you can see the exit curb. Touch the grass on corner exit at high throttle, and the lap is immediately invalidated.
Challenge 2: Red Bull X2019 at Sainte-Croix B Reverse
To mark Round 3 of the Gran Turismo World Series in Singapore, this trial pairs the Adrian Newey-designed Red Bull X2019 Competition with the sweeping, technical Sainte-Croix Layout B in Reverse.
The Danger Zones
- High-G Aero Transitions: On Racing Softs, the X2019 generates absurd aerodynamic grip. The car responds instantly, meaning lazy hands will induce snap oversteer. You need precise steering lock control.
- Sightline Adjustments: Running Layout B backwards completely changes your reference boards. Sweeping bridge sections invite excessive entry speed, making it easy to overdrive the front tires and scrub momentum.
- Trail-Braking Windows: Because the downforce bleeds off quickly as speed drops, heavy initial brake pressure followed by a rapid bleed-off is crucial to rotate the platform into Sainte-Croix’s 90-degree sector links.
Wheel Base Settings Reference
Dialing in a responsive, linear force feedback baseline is critical to catch rear snaps over Road Atlanta’s crests and manage the X2019’s high aero load.
