Maruti Suzuki’s focus on lower vehicle emissions To adopt new technologies to enhance
Fleet emission down by over 11.6% in last five years
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
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
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. This has been possible
through fuel efficiency improvements, reduction of exhaust emissions and development
of alternate fuel products during this period.
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.
Efforts in Alternate Fuel Technology:
Promoting clean fuel, Maruti Suzuki, was the first Company to introduce factory-fitted
CNG cars in India in 2006. It currently offers six dual fuel (CNG+Petrol) models
namely Alto, Alto K-10, Celerio, Wagon R, Eeco and Ertiga. The CNG variants of Alto
K-10 and Celerio were launched in 2014-15. Powered by the acclaimed Intelligent
Gas Port Injection (i-GPi) technology, MSIL’s CNG vehicles deliver the advantage
of best in class fuel efficiency, besides safety, reliability and performance

Future sustainable technologies
Working on future technologies, under the National Electric Mobility Mission Plan
2020 (NEMMP), Maruti Suzuki has demonstrated the Swift Range Extender (REEV). Swift
RE-EV is an electric vehicle with an engine driven generator.
The vehicle functions like a pure Battery Electric Vehicle (BEV) for customers who
commute short distances. Once the battery power is depleted, the on board IC engine
starts functioning and runs the generator for supplying power to the electric motor,
thereby eliminating the “range anxiety” issue generally associated with BEV’s. The
vehicle can be charged at home from a household power outlet.
