Green drive at CWG 2010


A small team at Maruti R&D has been preparing for this mega event since last eighteen months. Of course this was not for any medal wining competition. Our given target was to provide a fleet of environment friendly vehicles including hybrid and electric options to CWG 2010. I worked on design & packaging activities of these vehicles with my colleagues.

SX4 was chosen to make it a parallel hybrid electric vehicle (HEV). It means the vehicle can be driven from a petrol engine (1.2L) as well as from an electric motor(50KW) (providing zero emission) and also as combined power source i.e. engine+e-motor.

Such kinds of hybrid vehicles are available in the world from very few manufactures. E.g. Toyota Prius, Honda insight hybrid etc.

Even our parent company Suzuki, Japan has not made any parallel hybrid yet.

This vehicle is very fun to drive because it has pure I/C engine drive, E-drive, boosting with e-motor while combined drive and regenerative braking. Also due to having an AMT(Automatic manual transmission) you don’t need to pull gear shifter and there is no clutch paddle in this vehicle.

Finally the hybrid version of SX4 has achieved 30% more fuel economy than SX4 petrol version car with 1.6L engine.

Maruti Van ‘EECO’ was planed to redesign as an electric variant. As named electric, this vehicle runs from an electric motor taking electric energy from a Li-ion battery. The battery can be charged from household electric socket through an external charger. After full charging the vehicle can be driven 120km continuously. It does not have any combustion engine, so it does not make any pollution at traffic.

Finally a fleet of ten hybrids and three EVs were demonstrated at CWG 2010. It was driven on Delhi roads to transport CWG officials. These cars were widely appreciated by Govt. officials and foreign delegates. But these Hi-tech vehicles will not reach market right now (Not sure about near future also).

Hi Chiru Bhai..long time..

So we are putting our legs into a 'green future' !!

Heard a lot about the Prius..So Maruti Suzuki too is working on the hybrid cars..way to go Chiru bhai..

Go green..

@ Raj

It is difficult to launch currently because it will be very costly at market. The main reason of high cost is its battery. India does not have any high voltage Lithium ion battery manufacturer. To bring this car into market we need domestic battery manufacturer who will be able to develop high volt Li-ion battery. Our domestic battery manufacturers do not have enough fund and skill to develop these batteries. Here we need govt. to support financially. Then only these cars can come to the market. Importing batteries is not at all cost-saving option.
Chiru bhai!
Congratulations on these new developments at Maruti!
I've seen a lot of the Toyota Prius here in the US (the most sold hybrid car here) and some Honda Insight. If I'm not mistaken Ford and Chevrolet too have hybrid cars here in the US.
But this is a good start for India.
I have a question regarding the fuel economy.
Doesn't the better fuel economy come from the fact that a smaller engine is being used (I see that you'll have reduced from a 1.6L to a 1.2L- going from the normal SX4 to the Hybrid). That's one of the reasons why a bike (100 cc) has much better fuel economy than a car.

@Chiru

I saw the report on these cars on TV! We were all super impressed!

Way to go! :)

@ Dion
Yes, you are right that smaller engine gives better fuel economy. The total improvement of FE is contributed by combination of all the hybrid functions.i.e drive purely battery, regenerative braking (charging battery during braking, optimised gear shifting etc.)
Our SX4 hybrid although has a smaller engine, it can clock 0-100Kmph in just 12.3 sec. This is 1.5 sec. faster than original SX4 petrol version.

GM, ford, Nissan, VW all have hybrids. But Prius is the most popular HEV today.
@Chiru bhai,
Great to see that you're working on an exciting project
I'm sure that you'll help Maruti keep its legs into future to ensure a phosphorous future for our country.(sic)

By the way,the discussion between Dion and you seemed to go over my head-total "Mech-talk"!

This a distress call to all TWM folks. This has been the longest duration of inactivity for TWM. So is it that we are all too busy or have all of us hit the writer's block. Let's break the spell of inactivity....HOW?? WHAT SHOULD I WRITE ABOUT?? I have an incomplete draft, shall I post that? May be I will do a recap of the past few days..No mood to write paragraphs.. Connect the dots yourself.. * Kaminey - Movie was good, the ending could have been better..The bong mafia coming with a long gun to the fight scene was really comic..Fahid Kapoor ki acting mast thi..waifey aap log ye movie dekhey kya?? * Books - Finally I read the book Love Story by Erich Segal..Hmmm the story is good but the effect of the classic book has not yet got into me..Meanwhile I am also reading 'The Great Indian Novel' by Shashi Tharoor..I will surely recommend this book..Tharoor has splendidly blended the tales from Mahabharata into the modern Indian history.. *Movies - I watched 'Littl

"Trip Kela" season is back!!

"We had joy,we had fun,we had trip kelas every season but the things we used to plan were seasons out of time" Wow!! Seems like the "Kela" season is in the air again!! Why is it that whenever WE plan something ,something has to go wrong!! On our maiden trip to Goa, I had to back out coz my dad was just outta hospital.So I had to be at home.Before our second trip,we had so much discussion regarding a "reunion" trip to Darjeeling during Convo.What happened was evrybody backing out the last month.Raj said that he has already booked tickets for home.Rathz,supposedly, didn't get any tickets for returning to Kolkatta from Cuttack & there I was in Kol doing nothing.Though finally we did go to Digha & the trip was gud BUT our unbeaten record of "Flop Plans" continued. Now, we are probably gonna add an another feather in the cap.The highly anticipated Goa trip which had created so much ripples across the cyberspace(blog,gmail & orkut)
