iRacing Week 13 is live, and it opens up Season 4 content before championship standings start to matter. If you have been waiting to put laps on the new Caterham Academy 420R, line up in the Caterham Academy series, or take the Aston Martin Valkyrie AMR-LMH out for a real session, this is the window. No points are on the line during Week 13, which makes it the lowest-pressure opportunity you will get all season to learn new machinery, shake down setups, and decide what belongs on your Season 4 schedule before the results count.

What iRacing Week 13 Means for Season 4
Week 13 is the transition period between iRacing seasons. Series still run their full schedule, but no championship points are awarded and Season 4 content becomes available to drive for the first time. For drivers, that combination means real seat time in new cars before race results start touching your rating and your standing in official series. You get the chance to actually run the cars, find a setup baseline, and understand what each piece of hardware needs before any of it costs you points. The transition does not last long. Season 4 officially begins soon, and the pressure changes the moment that standings clock starts ticking. Use the time now.
The Caterham Academy 420R is the center of attention for open-wheel drivers this season. It anchors the new Caterham Academy series, which is structured around clean, disciplined racing rather than the attrition that comes with faster, more powerful machinery. The series is designed as a deliberate skills-development ladder, not a free-for-all. If building a proper open-wheel foundation in iRacing is the goal for Season 4, the Academy series deserves serious consideration. Multiple session types are available right now, before a single result touches your rating, which gives you a meaningful head start going into the first official week. The learning curve is real with any new car, and Week 13 is exactly the right time to climb it.
The Aston Martin Valkyrie AMR-LMH Makes Its iRacing Debut
For drivers who want the prototype end of the spectrum, the Aston Martin Valkyrie AMR-LMH arrives in Season 4 and is available to run right now. The car is built using real factory engineering data from Aston Martin’s WEC program, which means the behavior you learn in iRacing reflects how the actual car operates at the limit. That connection to real-world telemetry is the entire premise of the partnership, and it shows in how the car responds under load and over curbs. Week 13 gives you both ranked and unranked sessions to start working through the Valkyrie before your finishing positions count toward anything real. If GTP-class racing is where you are headed in Season 4, the time to figure that car out is now, not in the first race of an official series.
iRacing’s Shiny New Shakedown and iTested series are set up specifically for this window. Both are Week 13 series designed to put drivers in new-content cars with structured sessions and no full competitive stakes attached. Whether you are committing your whole Season 4 to the Valkyrie AMR-LMH, the Caterham 420R, or you are still figuring out your schedule, a handful of iRacing Week 13 sessions will give you more useful information than any spec sheet ever will. Check the official schedule to see which series match your time zone and skill level. Season 4 is close, and this is the last clean opportunity to get comfortable before the results start to matter.
