Two Caterhams are coming to iRacing Season 4 2026: the Caterham Academy and the Caterham 420R. Both arrive as a single purchase, and they sit in different license classes. The Academy is a Class D entry with lightweight mechanical grip and pack racing built around clean driving. The 420R steps up to Class C with a higher power-to-weight ratio and more throttle sensitivity. If you have followed the speculation about a Caterham iRacing Season 4 addition, this is the official confirmation from the August 2026 development update.

Caterham Academy: Class D, Mechanical Grip, Pack Racing
The Caterham Academy traces its roots to the Lotus 7 design from the 1950s. In real-world club racing, the Academy class runs identical cars at entry-level competition, which produces close racing decided almost entirely by driver skill rather than car setup. iRacing’s Academy is positioned for the same kind of racing: Class D, lightweight, driven primarily by mechanical grip rather than aerodynamic downforce.
Pack racing in the Academy will rely on slipstream and clean positioning rather than outbraking everyone into corners. The Caterham’s open-wheel layout and minimal bodywork mean drafting plays a genuine role on circuits with long straights, while the mechanical grip bias puts a premium on smooth corner entry and exit. For iRacers used to formula-style cars at the D license level, the Academy offers a different dynamic: less aero, more chassis feel, and racing that happens in a crowd.
Caterham 420R: Class C, More Power, Throttle Discipline
The 420R sits one step above the Academy in both class and intensity. The real-world 420R is a road-legal version of Caterham’s race-bred Seven platform, with a 2.0-liter engine producing around 210 horsepower in a car that weighs under 550 kilograms. That power-to-weight ratio is aggressive, and throttle control out of slower corners will be the primary challenge behind the wheel.
At Class C, the 420R races against a different set of cars on iRacing, and the license requirement means most iRacers will have to work their way up through the Academy before reaching it. That progression ladder is a natural fit for how the two cars are being sold together. You start in the Academy, learn the platform, and advance to the 420R when your license and driving allow it.
One Purchase, Two Cars
iRacing is bundling the Academy and the 420R as a single content purchase. This follows the pattern iRacing has used for other paired cars, like multi-variant content packages where both configurations share a price point. The exact purchase price has not been confirmed ahead of the Season 4 launch.
For iRacers looking at the Academy specifically, this is one of the more accessible entry points into open-wheel sports car racing on iRacing. The D license requirement is achievable for newer members, the car is not technically demanding in the way that a full-aero single-seater is, and the racing style favors racecraft over setup knowledge. If you have raced the existing Caterham Seven content or spent time in D-class oval racing, the Academy should feel accessible from day one.
The Caterham Academy in Real-World Club Racing
The Caterham Academy and 420R have a specific place in British club motorsport. The Academy operates as a one-make series where every competitor runs the same specification car, same tyres, and same setup within the class rules. This is deliberate: the series is designed as a fair introduction to circuit racing, where results come from driving rather than car preparation advantage. The 420R runs in a more open class structure where the car’s performance ceiling is the primary limit rather than a spec ruleset.
Both cars run on real-world circuits across the UK and European calendar. Brands Hatch, Snetterton, Donington Park, and Oulton Park are regular Caterham Motorsport venues. On iRacing, the Academy and 420R will fit into road circuit series using tracks in iRacing’s UK and European road catalog. Brands Hatch and several of the other Caterham venues are already in iRacing’s track library, which sets up a natural fit for any official series using these cars.
How This Differs from Existing Caterham Content
iRacing already has Caterham content in a different context. The Caterham Seven appears in iRacing Arcade, the console spin-off, as free content in the first post-launch update. That is a separate product entirely, and the console Caterham is not the same as these two club-racing cars coming to the main iRacing sim. The Academy and 420R are purpose-built for the competitive license structure and official series environment of the full sim.
The partnership with Caterham Cars for these two cars is described as a formal collaboration, giving iRacing access to the technical specifications for both models. Both cars arrive in the Season 4 2026 build in September.
Where the Caterham Academy Fits on the iRacing Road Ladder
Class D is the entry point for iRacing’s road license structure. The Caterham Academy arriving at Class D puts it alongside the Mazda MX-5 and other D-class road content as one of the accessible starting points for new road license members. The natural progression for a new road racer is to earn a D license through time trials or rookie series, then choose a D-class car that suits their preference. The Academy gives road-focused new members a lightweight, mechanical-grip option rather than the more common front-engine touring car starting point.
At Class C, the 420R sits in a more competitive tier. Moving from the Academy to the 420R within the same car family is a clean progression path, and owning both with one purchase removes the cost barrier to trying both. For iRacers who spend time in D-class and earn their C license, the 420R is already in their content library waiting for them.
