Where each one leads
Alfa Romeo Giulia
Ahead on none of the like-for-like measures.
Volkswagen Passat
- On Canada's official test the most frugal 2022 Volkswagen Passat uses 8.3 l/100 km, the 2026 Alfa Romeo Giulia 8.7.
- New Volkswagen Passat cars registered in Europe in 2022 average 122 g/km of CO₂ on the WLTP test, against 168 for the Alfa Romeo Giulia in 2022.
- Measured by the cars' own fuel meters, the diesel Volkswagen Passat uses 6.0 l/100 km on the road, the Alfa Romeo Giulia 6.4.
- Measured by the cars' own fuel meters, the petrol Volkswagen Passat uses 7.3 l/100 km on the road, the Alfa Romeo Giulia 9.8.
Too close to call: MOT pass rate against cars of the same age; dutch odometer readings judged illogical.
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
