Maruti Suzuki’s focus on lower vehicle emissions:
To adopt new technologies to enhance fuel efficiency Fleet emission down by over 11.6% in last five years

New Delhi, June 4th, 2015: On the eve of World Environment Day, car market leader Maruti Suzuki India Limited (MSIL) said it would continue its work on bringing down vehicle emissions as a means to promote clean air and delight customers.

Outlining its commitment towards bringing environment friendly products, Mr. Kenichi Ayukawa, Managing Director & CEO, said, “Maruti Suzuki has always been known for class leading fuel efficiency. In the last few years, the Company has worked systematically towards reducing vehicle emissions and achieved new benchmarks. The recent new models, product upgrades and even minor changes have been substantially more fuel efficient than the outgoing ones. With Auto Gear Shift technology the Company is able to offer the convenience of an automatic without the need to emit more.”

He added, “Going forward, we will continue our focus on investing in new technologies and strengthen our capability to bring down emissions per vehicle by enhancing fuel efficiency of our cars.”

Maruti Suzuki’ parent company Suzuki Motor Corporation had showcased three new technologies at the Geneva Motor Show which include a new-generation light weight platform, a new downsized direct-injection turbo petrol engine called BOOSTERJET and the SHVS mild hybrid system. These future technologies will bring down emissions while raising vehicle performance. These technologies could find relevance in India and the Company may explore these options as per customer requirements.

Fleet Emissions down by over 11.6 % in five years

With focussed efforts, Maruti Suzuki has been successful in bringing down the weighted average of CO2 emission by over 11.6 % in last five years.

Kaizens in fuel efficiency

As a focused initiative, Maruti Suzuki engineers worked towards improving fuel efficiency and bringing down emissions per car in 2014-15. The three most fuel efficient cars in India are all from Maruti Suzuki: Celerio, DZire and Ciaz.

Some of the innovations included;
a) Introducing changes in engine hardware to improve thermal efficiency and engine calibration.
b) Optimizing transmission gear ratios for better drive and fuel efficiency.
c) Improved aerodynamic styling and weight reduction initiatives
d) Making compact combustion chamber
e) Enhancing compression ratio on gasoline engine
f) Adopting advanced thermal management system along with low friction engine oil and modified fuel injection system that assist faster warm up to improve engine efficiency of diesel engine.
g) Introducing new generation alternator management to optimize the charging of battery through alternator and hence contribute to better fuel efficiency.
