Nissan Gravite CNG vs Maruti Suzuki Ertiga S-CNG: Performance and pricing comparison

CNG-powered family cars continue to gain popularity as buyers look for lower running costs without moving to EVs. Nissan has entered the space with the Gravite CNG, using a dealer-installed twin-cylinder retrofit kit that keeps its 7-seat layout usable. Maruti Suzuki, meanwhile, continues with its factory-fitted Ertiga S-CNG, a model that already has a strong presence among family and fleet buyers. While both target economic commuting, they approach the segment from very different ends of the market.

Nissan Gravite CNG vs Maruti Suzuki Ertiga S-CNG: Space and practicality

The Ertiga is the bigger vehicle in this comparison, measuring 4,395 mm in length with a 2,740 mm wheelbase. That translates into a roomier cabin, especially for third-row passengers.

The Gravite is more compact at 3,987 mm long and rides on a 2,636 mm wheelbase. This, in principle, restricts the amount of legroom available inside the cabin.
