If you cover 20,000+ km/year mainly on motorways, a modern diesel often saves money (4-5 l vs 6-7 l per 100 km). Check if diesel bans apply in your city. For short urban commutes under 15,000 km/year: petrol or mild hybrid.
›Is a hybrid worth it for commuters?
Full hybrid (e.g. Toyota Corolla): saves 20-30% in city traffic. Mild hybrid: 10-15%. The premium pays off in 3-4 years for heavy city use. For pure motorway commuters the hybrid benefit is smaller.
›Most reliable commuter brands?
Toyota and Mazda consistently top reliability surveys. Hyundai/Kia have improved a lot recently. VW Group (VW, Skoda) sits solidly in the middle field.
›Used or new as a commuter car?
A 2-3 year old used car with low mileage (under 40,000 km) is often the best choice: biggest depreciation already absorbed, still near-new quality.
