Where each one leads
Audi RS 6 Avant
Ahead on none of the like-for-like measures.
Porsche Macan GTS
- On Canada's official test the most frugal 2026 Porsche Macan GTS uses 12.2 l/100 km, the 2026 Audi RS 6 Avant 14.4.
- New Porsche Macan GTS cars registered in Europe in 2022 average 256 g/km of CO₂ on the WLTP test, against 294 for the Audi RS 6 Avant in 2022.
Only measures that do not depend on how many cars were sold: pass and failure rates against cars of the same age, ratings, fuel use and CO₂. How we compare
