Diesel Midsize SUVs Ranked by Mileage

Diesel SUVs may not dominate headlines anymore, but for buyers who prioritise long-range efficiency, strong torque, and lower running costs, they still make a lot of sense—especially in India. While some carmakers are stepping away from diesel, brands like Hyundai, Kia, Tata, and Mahindra continue to keep the option alive in the midsize SUV space.

In this article, we rank the diesel midsize SUVs available in India based on ARAI-claimed fuel efficiency, from least to most efficient. Do note, real-world mileage will vary depending on driving style, terrain, and traffic conditions.

Note: ARAI figures for diesel variants of upcoming models like Tata Curvv and Mahindra Thar Roxx are yet to be officially revealed.

3. Kia Seltos

ARAI mileage: Up to 19.40 km/l

The Kia Seltos continues to be a strong contender in the midsize SUV segment, offering a well-rounded package of features, performance, and design. Its diesel engine is tuned more for refinement and drivability rather than outright efficiency, which reflects in its mileage figures.

Mileage (ARAI):

While it sits at the bottom of this list, the Seltos still delivers respectable efficiency, especially considering its feature-loaded nature.

2. Tata Sierra

ARAI mileage: Up to 21.26 km/l

The reborn Tata Sierra brings a blend of retro charm and modern engineering. Positioned between the Curvv and Harrier, it introduces a refined diesel setup with improved torque figures and impressive fuel efficiency.

Mileage (ARAI):

Interestingly, the Sierra’s automatic variant is among the most fuel-efficient diesel automatics in this segment, making it a strong choice for urban buyers who want convenience without compromising economy.

1. Hyundai Creta

ARAI mileage: Up to 21.80 km/l

The Hyundai Creta continues to dominate the segment—not just in sales but also in efficiency. Its lighter construction and well-optimised diesel engine give it a clear edge in fuel economy.

Mileage (ARAI):

The Creta’s combination of excellent mileage, proven reliability, and widespread service network makes it the most efficient diesel midsize SUV currently on sale in India.

Final Take

If your priority is maximum fuel efficiency, the Hyundai Creta leads the pack. The Tata Sierra follows closely, offering a modern alternative with strong automatic efficiency. Meanwhile, the Kia Seltos remains a solid all-rounder, even if it trails slightly in mileage.
