The Best GT3 Championships to Watch as a New Fan

The GT World Challenge Europe (GTWCE) is the logical starting point for most new GT3 fans. Run by SRO Motorsports, it is the flagship European championship and the series most closely associated with the GT3 category globally.

GTWCE runs in two parallel competitions: the Endurance Cup (three long-distance races at Spa-Francorchamps, Paul Ricard, and another European venue) and the Sprint Cup (short sprint rounds across Europe from April to October). Both share the same cars and many of the same teams; some drivers contest only one format, others run both.

The grid size is enormous — Endurance Cup rounds at Spa regularly attract 60 to 70 cars. The manufacturer diversity is unmatched: Ferrari, Porsche, Lamborghini, Mercedes-AMG, BMW, Audi, McLaren, and Aston Martin are all typically represented. The racing is close, the circuits are iconic, and SRO streams everything free on YouTube.

If you watch one GT3 championship, start here.

The IMSA WeatherTech SportsCar Championship's GTD and GTD Pro classes are North America's premier GT3 platform, with a structure distinctly different from European GT3.

IMSA races at circuits that feel specifically American: Daytona International Speedway, Road Atlanta, Laguna Seca, Watkins Glen, Mid-Ohio. The flagship event, the Rolex 24 at Daytona, runs in January — 24 hours of racing at America's most famous circuit, including a banked oval section unique in international GT3.

The GTD Pro class runs professional-only driver lineups, while GTD allows Pro-Am combinations. Both share the grid simultaneously, creating multi-class racing across a full season.

IMSA's broadcast deal with Peacock makes it less accessible internationally than GTWCE, but the racing quality is extremely high. The manufacturer mix is slightly different — Corvette, Lexus, and Lamborghini are particularly strong — giving it a distinct character.

The British GT Championship occupies a different niche from the global series: it is a national championship with a devoted following, intimate paddock access, and racing at circuits that feel distinctly British. Snetterton, Brands Hatch, Silverstone, Spa (for the finale).

British GT has two classes: GT3 and GT4. The GT3 class typically attracts 15 to 25 entries — a smaller grid than GTWCE but with a different atmosphere. Paddock access is often free or low-cost, teams are accessible to fans, and the Pro-Am culture is strong.

For new UK-based fans, British GT is a genuinely excellent entry point. Tickets are affordable, many rounds are held at circuits within reasonable travelling distance of major cities, and the familiarity of teams and drivers builds quickly over a season.

The championship broadcasts on ITV4 in the UK, making it the most accessible televised motorsport in the country after Formula 1.

The Deutsche Tourenwagen Masters (DTM) is Germany's premium motorsport series, and since switching to GT3 machinery in 2021 it has become one of the most visually spectacular championships in the world.

DTM is pure sprint racing: two races per round, each 55 minutes, at circuits including the Nürburgring Grand Prix circuit, the Red Bull Ring, Hockenheim, and Brands Hatch. The format is straightforward and accessible — no endurance complexity, just qualifying and racing.

What distinguishes DTM is its production values. The broadcast, team hospitality, and circuit presentation are top-tier. DTM has always prioritised spectacle, and that culture survived the GT3 transition. There are fireworks on the grid and a festival atmosphere that differs from the more measured SRO events.

DTM uses a reverse grid format for Race 2 of each round: the top ten from Race 1 start in reverse order, guaranteeing overtaking and drama. It is divisive among purists but genuinely entertaining for newer fans.

For most new GT3 fans, the GT World Challenge Europe is the right starting point. The combination of free YouTube access, enormous grids, iconic circuits, and year-round racing makes it the most rewarding championship to follow from scratch.

Start with a single GTWCE Endurance Cup race — the Spa 24 Hours is the ideal introduction, even if you only watch the highlights. Then follow a full Sprint Cup season from the beginning, picking two or three teams to follow through the rounds.

Once you are engaged with GTWCE, branch out. If you are in North America, add IMSA GTD. If you are UK-based, attend a British GT round in person. If you want pure sprint intensity with high production values, sample a DTM weekend.

GT3 is global enough that you will never run out of racing to watch. The priority is to start somewhere, build familiarity, and let the depth reveal itself.
