Where each one leads
Cadillac XTS
- On Canada's official test the most frugal 2019 Cadillac XTS uses 11.0 l/100 km, the 2026 Porsche Panamera 11.4.
Porsche Panamera
- Against cars of the same year, the Porsche Panamera comes out better in New York safety inspections (fails 71% less often than average) than the Cadillac XTS (fails 42% more often than average).
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
