Maruti Suzuki Brezza CBG (Compressed Biomethane Gas): A New Green Revolution on Wheels with 25.51 km/kg Efficiency


Maruti Suzuki Brezza CBG

Maruti Suzuki Brezza CBG: In a scenario where Compressed Biogas (CBG) mimics the chemical properties of CNG, minor modifications appear to be required for vehicles that already use CNG. Despite the impending dominance of electric powertrains in the automotive landscape, manufacturers continue to explore alternative, environmentally friendly, and cost-effective fuel options. A notable example is Compressed Biomethane Gas (CBG), which shows great promise. Maruti Suzuki, India’s largest car manufacturer, has taken a step in this direction by introducing its first CBG-powered vehicle at the Bharat Mobility Expo.

Maruti Suzuki Brezza CBG Power And Performance

Maruti Suzuki Brezza CBG

The Maruti Suzuki Brezza CBG engine maintains its prowess with the advanced K-series dual jet, dual VVT petrol engine. In petrol mode, it yields a commanding 103.1 PS of maximum power and 136.8 Nm of peak torque. Transmission options encompass 5MT and 6AT. Transitioning to CNG, the output registers at 87.8 PS and 121.5 Nm, coupled exclusively with a 5-speed manual transmission. The Brezza CNG achieves an impressive mileage of 25.51 km/kg.

With CBG integration, the figures align closely with the CNG counterparts. CBG’s calorific value and chemical composition closely resemble those of CNG, boasting methane content exceeding 90%. With these characteristics, CBG emerges as a viable green fuel alternative to petrol and diesel, promising consistent performance akin to the CNG variant. The Brezza CBG is anticipated to extend its CNG availability to the LXi, VXi, and ZXi trims.

Maruti Suzuki Brezza CBG Features:

At the Bharat Mobility Expo, the showcased Maruti Suzuki Brezza CBG exhibits minimal exterior updates, distinguished by bold fuel-type identification stickers on the side. The retail version will feature standard CBG stickers on the front and rear windshields. The equipment roster mirrors that of the corresponding CNG variants.

To complement the CNG powertrain, certain adjustments have been implemented, ensuring their availability in CBG variants. For instance, Maruti’s CNG vehicles incorporate an intelligent injection system for optimized combustion and a re-engineered suspension to accommodate the gas tank’s weight. Enhanced engine durability and lifespan result from the integration of advanced components. A micro switch facilitates engine shutdown during refueling, and the gas tank features stainless steel pipes and leak-resistant materials. The auto-switch allows seamless transitions between CNG and petrol. Additional features include a fuel level indicator and an NGV receptacle, facilitating safe and swift CNG refueling. These advantages extend to the Brezza CBG variants.

CBG: A Potential Game-Changer in Reducing CNG Import Expenditure

Beyond its application in automobiles, CBG presents a plethora of advantages as a renewable green fuel, sourced from cattle dung, agricultural residue, sewage treatment plant waste, municipal solid waste, and sugarcane press mud. Given India’s substantial livestock and agricultural resources, compressed biogas holds vast potential. Beyond the automotive realm, CBG stands poised to replace CNG in the industrial and commercial sectors, promising a significant reduction in the country’s CNG import dependence.
