Honda’s Civic Engine Is The Most Efficient Non-Hybrid Inline-Four In Current Production

The Toyota Corolla and Hyundai Elantra are both remarkably fuel-efficient, but one small sedan beats them both when it comes to delivering the best MPG performance from a non-hybrid four-cylinder engine on the road today. That sedan is the Honda Civic, and in particular, models running the standard-kit two-liter inline four-cylinder. This engine’s roots trace back to the original launch of the K-Series in 2001, and is well known as one of the most reliable engines in an affordable car today.
