A very modern and well-known vehicle that continues to prove how efficient it can be. For typical drivers who don’t regularly travel long distances, the Prius delivers an average fuel economy of around 46 mpg. It remains a benchmark for hybrid efficiency.
Still unsure about Korean automakers? The Kia Niro is unlikely to disappoint. Introduced in 2016, it remains popular thanks in part to its fuel efficiency.
