To Aseem's post...Aseem always has this opinion about the Esteem being faster than Baleno...however, I feel other wise...
All data is from ACI...so feel free to refute their trustworthiness...however, I believe them Acceleration
Baleno 0-100 : 11.1 Sec 0-60 : 4.92 sec Esteem : 0-100 : 11.49 sec : 0-60 : 5.01 sec Swift : 0-100 : 12.29 sec : 0-60 : 5.22 sec |
Buffetan, you yourself have mentioned that Accent Tornado has more BHP but still Baleno is faster. So facts can be twisted and turned. You have mentioned one magazine and you yourself will acknowledge most other magazines give Esteem to be faster in 0-100. Now you will talk about their credibility, so the debate will go on and on as to who to believe. However we must agree there are quite a few magazines who put Esteem ahead of Baleno. I am qouting Indiacar on 0-100:
Car Name 0-40 0-60 0-100
Maruti Esteem 3.00 secs 5.16 secs 12.27 secs
Maruti Baleno 2.72 secs 5.02 secs 12.77 secs
Distance 0-100kmph
Car Name 0-40 0-60 0-100
Maruti Baleno 15.45 mtr 44.64 mtr 222.03 mtr
Maruti Esteem 17.20 mtr 44.52 mtr 209.21 mtr
Here is a qoute from the road test of another reputed magazine, autocarindia for Esteem:
The 1.3 petrol, although ancient, is one of the finest engines available in India: built largely out of aluminium, it is refined, powerful, and frugal and loves to be revved. In fact, it can accelerate quicker than an old Honda City VTEC! This engine is virtually bombproof, and a sipper, averaging an amazing 10.1 and 16.7kpl in city and on the highway.
What helps both engines along is the excellent gearbox, which is light and precise, although the too-tall gearing affects driveability somewhat. However, the tall gearing makes the car a composed highway cruiser.

Overdrive also rates Esteem 0-100 faster than Baleno. So that makes it three magazines as opposed to your ACI figures. Now that brings me to the second part of what you have mentioned:

As mentioned earlier:

To put it plainly, Esteem is less torquier than Baleno. Therefore you have smartly posted figures that help you prove a point. Baleno being a torquier car will always imply that its torque will peak at a lower RPM band, doesnt mean its faster than Esteem. If you put Accent Viva Crdi on 4 gear and accelerate from 30-100, Baleno will be seeing the exhaust smoke of the CRDI as it has more torque than the Baleno. The torque of Esteem is 105@3000 RPM as opposed to 134@3000 RPM for Baleno. Compared with lower torque and tall gearing, Esteem's acceleration on 3rd and 4th gear is a lot less than Baleno, but how about posting the figures of 0-100 on 2nd gear for both the cars?
Hyundai accent CRDI is 187@2000 RPM so its even more torquier than Baleno, but doesnt make it faster??? just makes it more drivable and increases acceleration figures from 30-100 kmph on 4th gear as opposed to Baleno. So just like Accent CRDI is not faster than Baleno, similarly between 0-100 if revved to the limit, Esteem is faster than Baleno, I am not talking about the drivability here.
Here is something that will clear the concept about torque:
http://www.newton.dep.anl.gov/askasc...9/eng99128.htm Practically speaking, however, a high torque engine will have faster response to the accelerator pedal from a lower RPM. A low torque engine may require the driver to shift into a lower gear to attain higher RPM's before maximal acceleration can occur. Diesels tend to produce pretty much the same torque at all RPMs and will give good throttle response. But, small displacement sports cars like the Honda S2000 require the engine to be revved to very high speeds to produce much power and tend to produce proportionally lower torque and power at low RPMs. To quote a friend of mine who test drove an S2000, you have to drive it like you stole it to make it go fast. Of course, for sports car enthusiasts, this is considered fun.
So agreed third gear acceleration of Esteem is no way near as good as Baleno, but doesnt mean its slower. It has to be revved hard like a sports car. And if its about driveability, than in City conditions, Accent CRDI is more drivable than Baleno due to its awesome torque.
Coming to your last point, about Baleno having 94 bhp as opposed to 85 bhp for Esteem means it has more power. Agreed, it has more power, but it has to tow more weight as opposed to Esteem. The gross weight of Esteem is 860 as opposed to 975 for Baleno, thus the effective power to weigt ratio of Esteem is a ton.
85:860==== 99 BHP per thousand kgs.
94:975==== 96 BHP per thousand kgs.
Finally, I am no advocate of Esteem. I am just stating facts, and not jiggling around with them to prove a point. Take this in the right spirit.
