Design & Looks

The new CNG version keeps the Brezza’s compact SUV styling – sharp front grille, muscular wheel arches, and the familiar roof‑rack. The big change is the placement of the gas cylinder. Instead of the usual roof‑mounted tank, engineers are fitting a slim, reinforced tank under the floor pan. This means the roof line stays clean and the rear hatch looks unchanged.

Because the tank sits low, the boot space grows by about 30‑40 litres compared with the current CNG Brezza. Owners will notice a flatter floor and more room for groceries or a small suitcase.

Performance & Mileage

The powertrain stays the same: a 1.5‑litre K15B petrol engine paired with a CNG kit that delivers roughly 100 hp and 130 Nm of torque. With the under‑body tank, Maruti claims a real‑world mileage of around 22 km/kg, a slight bump over the roof‑tank version that usually clocks 20‑21 km/kg.

Driving feels smoother too, as the weight of the cylinder is now centred low in the chassis, improving balance and handling on city roads.

Price & Rivals

Pricing has not been officially announced, but industry sources expect the under‑body CNG Brezza to sit a little higher than the current CNG model – roughly ₹8.5‑9 lakh (ex‑showroom). That still keeps it cheaper than rivals like the Hyundai Venue CNG and Tata Nexon CNG.

Key competitors:

  • Hyundai Venue CNG – slightly higher price, less boot space.
  • Tata Nexon CNG – similar price, but heavier and less fuel‑efficient.
