GTSerien

GTSerien, literally “GT Series” in German, is a term used in German-language motorsport to designate championships featuring Grand Tourer (GT) cars. The label has been used for both historical national championships and current regional or international GT racing where production-based, road-derived cars compete. The series typically runs multiple rounds per season on circuits in the host country, with formats ranging from sprint races to endurance-style events.

Cars competing in GTSerien are usually designed to GT3- or GT4-specifications, or their domestic equivalents, and are governed by balance-of-performance rules or homologation templates to maintain parity between manufacturers and teams. Races often mix professional and amateur drivers, with classifications and formats intended to promote close competition and accessibility for a broader field.

In terms of governance, GTSerien events are generally sanctioned by the national motorsport federation and aligned with FIA GT regulations or regional variants, sometimes under a dedicated organizing body. Notable manifestations include historical national GT championships in German-speaking regions and contemporary events such as the ADAC GT Masters, along with various cross-border GT series in Central Europe. The concept has supported driver development by providing a pathway to higher-level sports-car racing and has influenced marketing strategies for participating manufacturers.
