This huge change in the dynamics of the diesel-powered small car segment has completely changed the list of ten most fuel-efficient diesel-powered cars in India, which is now as follows:

Hyundai Aura

Another mass-market carmaker that stuck to its diesel plans in the BS6 era is Tata, and the Altroz happens to be its most affordable and efficient diesel car on sale.

The hatchback derivative of the Hyundai Aura, the Grand i10 Nios might be smaller and lighter than the former but is surprisingly less efficient.

The Kia Sonet has created a lot of ripples in the Sub-four metre compact and has given its competition some sleepless nights with its high demand among Indian car buyers.

The Honda WR-V might not have been as successful as its competitors in the sub-four metre compact SUV/crossover segment. However, this jazzier version of the Honda Jazz gets substantial revisions to its styling on the outside and an added versatility of an optional diesel engine.

The oil burner is the same 1.5-litre diesel engine which is there in the City and Amaze as well. Available with only a 6-speed manual gearbox, this engine in the WR-V makes 100 PS of power and 200 Nm of torque, and ensures a fuel economy of 23.7 kmpl.
