This is my first ownership review (Santro 2009 Model), so please bear with me.
Anshuman in Brio's Official Review mentions
"Make no mistake, this is no Santro 1.1L engine, but neither will Brio owners complain of poor torque." &
GTO has included Brio in Enthusiast's Car's List 2013.
1. Why Santro?
It was October 2009 & we had a 2000 model Santro (First model launched in India, even before the ZipPlus/ZipDrive w/o power steering). It had clocked 85,000 KM. Even though its condition was very good, but the car had started to look aged. So, we felt like changing the car. I was in college then, & this car was going to be primarily for my daily commute. So, I wanted a cheap car, that would not eat up my dad's money in maintenance. Past experience with Santro was great & even though the more modern sibling i10 was just 10,000 costlier, I felt like going in for new Santro(GLS) again. Initially my running was just 10KMs daily, so did not consider Diesel/CNG.
This car was ONLY for in-city commuting. For highways, we have Ritz ZXi.
BEFORE CNG(0-12K KMs)
2. What I like about it?- Torquey Engine: Awesome Low,Mid & even High range Torque
- Spacious Feel: Tall boy design, simply love it.
- Reliable
- Maintenance Free
- Easy spare parts availability
- Easy ingress & egress
- Easy maneuverability
- Decent ground clearance: In my daily city commute because of metro construction I many a times have to get down the road on side kachcha lane with bad humps & holes & not even once did I scrape the underbelly.
- Good Top Speed: More than 155 Km/h
3. What I don't like about it?- Low Power: To pull a fully loaded car the engine needs to really worked upon.
- Weird Suspension: I call it weird because neither is the ride quality good, nor is the handling that great.
- Poor FE: Not so great FE, considering the car of this segment.
- Practically No features: Our top model just has front power windows & internally adjustable ORVM. (I am calling these to be features, because Maruti LXi/LDi variants do not provide power windows even in the new cars & Amaze does not have adjustable mirrors in 2 variants.
)
4. Why CNG?
By Feb 2011, I was in job & my daily commuting increased to about 80KMs. The Santro was 16 months "new" to me & had clocked 12,000 KMs. So, I did not feel like changing the car & putting in a couple of lakhs for a Diesel upgrade. The 3 free services were over & the car maintenance was handed over to my trustworthy local mechanic. He advised me to go in for a CNG & ensured me that there would be no issues whatsoever as Santro was the most common car with Aftermarket CNG fitments.
So agreed to get the conversion done with my 3 years extended warranty getting void.
5. About CNG Kit.
I don't remember the brand, but it was not a BRC & not a sequential kit.
Lamda is not installed & a timing advancer device is installed. It costed me 23,500.
AFTER CNG(12K - 60K KMs)
6. What I like now? - Cheapest per KM cost
- Torquey & revv-loving nature intact
- Top-Speed: Even after running 50K KMs on CNG, the car crosses 150Km/h
7. What I don't like now? - Weirder suspension: Even with one person in the rear, the car bounces like a yo-yo.
- Lower Power: With full load in the car & AC on, the engine feels like giving up on me. One time we 6 people had to adjust in the car & I had to really revv it hard to make it moving. On that occasion I found the mileage coming down to 10KM/kg.
- Jerky Petrol Ride: My mechanic says that its the ECU adjusting to the CNG supply, so in petrol mode the ECU does not supply sufficient petrol to the bay. I think maybe its because of a faulty fuel pump? As most of the times the petrol in my car is less than half a tank.
8. Turning points. - Boot Lid rattling solved: Right from the beginning of the car, there was an annoying rattle from the boot lid. Whenever I took up this problem with the Service center, they used to temporarily solve the problem & hand over me the car. The car used to run fine for few thousand KMs & then again the problem used to resurface. Even my local mechanic could not find a fixed permanent solution to the problem. I had somewhat started to somewhat live this problem, but around 40K KM I finally decided to give up & sell off this car.
Told my mechanic to give one last shot. Even though the problem could not be found, but he twisted the boot lid lock a little, & voila the problem was solved. Now the boot closes a bit tight, but NO RATTLES.
- New Wheels:
Just when I was getting over the joy of no rattles in my car, at around 45K KMs, I got my ride a new set of alloys along with Michelin XM2, 155/70 R13. Oh boy, costed me Rs 25,000 but what a change.
The car seems to be infinite times gripper than the stock Goodyear's. Ride has improved, so has high speed stability & to top that my mileage has improved by at least 10%.
With AC mileage has improved from 18KM/Kg to 20KM/Kg.
Without AC mileage has improved from 20KM/kg to 22KM/KG
In CNG, such mileage increase means significantly lesser trips to CNG station.
But as you can see in the pic, the alloy has a top plastic like layer coming off its surface. The dealer says that just an extra paint protection layer, & even if it comes off, the alloy will still look cool.

9. Maintenance - Servicing: Oil & oil filter change at every 5,000KM & Air filter change at every 10,000KM as CNG efficiency starts to deteriorate with filter getting dirty. Each service without air filter costs me around Rs. 1100, & 100 bucks more with the air filter change.
- Parts Changed:
NGK spark plugs at 30K KM.
Brake pads twice at 25K & 50K KM.
Wiper blades at 30K KM.
Radiator flush & coolant change: 50K KM.
Engine bearing at 60K KM : Costed me Rs. 600.
Driver side wheel bearing at 60K KM : Costed me Rs 900.
Asked my mechanic about decarbonisation : He simply refused to do it stating that the oil change at 5K KM has no chance of any carbon in the engine bay.
- Home treatments: I don't like to put a lot of self labor into my car. But once a week my domestic help washes the car with normal water & I clean my air filter every 2500KMs at home.
I try to warm up & cool off my car in Petrol.
10. Future Plans
Touchwood, the car has not been with any accident at all. I had to make an insurance claim once when some stupid street kid hit my front windscreen with a ball & caused a crack in it. I lost my 30% NCB
My friends have tried to talked me into selling this generation old car but I simply find no reason whatsoever to sell this car, which is dirt cheap to run & maintain & has no issues at all.
The only reason which I can think for selling this car is that now I can afford a bigger better car & have got a little bored with this.
But now that I am married, I can give this car to wifey & can buy a bigger car.
I don't feel like upgrading the basic ICE of my car, as it will hardly have any value in re-sale.
But I feel like upgrading the suspension of Santro. Any suggestions on which brand/model to go for a CNG car are most welcome.
Will be soon getting a complete polishing/rubbing of the car done for the first time.
11. My Feelings for this car
A great car for in city daily commuting, especially if only driver+passenger have to travel.
