avgasporten

Avgasporten is a term used in some Nordic and European motorsport circles to describe a niche form of competition that centers on exhaust performance and emissions management within a racing context. The name combines avgas, referring to aviation gasoline, with sporten, the Swedish word for sport, reflecting an approach that links high-speed driving with fuel and exhaust considerations. There is no single global governing body for avgasporten; most activities are organized by regional motoring clubs and track operators that apply general safety and environmental requirements.

Events typically take place on closed race tracks or controlled airfields, featuring timed runs and head-to-head heats. Vehicles range from purpose-built race cars to modified street cars that conform to a set of technical rules governing exhaust components, noise levels, and fuel usage. Scoring often includes speed and lap time, as well as measured exhaust output, fuel efficiency, and compliance with noise limits.

Equipment and safety requirements emphasize standard race gear and data-logging systems to document performance and emissions. Teams may use fixed or modular exhaust configurations within the allowed limits, with inspections and seals used to ensure fairness and safety.

History and reception: the movement emerged in parts of Northern and Central Europe during the 2000s as interest in sustainable or responsible motorsport grew. Critics argue that emissions considerations can conflict with peak performance, while supporters view avgasporten as a venue to promote cleaner technologies and innovation within racing.
