Perhaps the most important thing to account for when buying your car is its on-road running costs, namely its fuel efficiency. Petrol isn’t cheap, so most drivers prefer a car that doesn’t simply guzzle gas. For example, the Swift is one of Suzuki’s most fuel-efficient vehicles at 4.6-4.8L per 100km, while the 2021 Jimny sits at around 8.2L over the same distance.
