Car & Bike Automatic transmission cars available in the Indian market?

How does ABS (Anti Lock Braking system ?) help ?

When you apply brakes normally at high speed, their is a chance that brakes might lock and cause the car to skid and go out of control.
When learning driving an experienced driver will tell you that the best way to apply brakes in this situation is to apply the brakes in quick succession, i.e. to take your foot off the break pedal and put it back on in quick succession thereby jerking the car to a stop and preventing skidding. ABS does that automatically. That is even if you have your foot pinned down on the brake lever it will apply the brakes as if you were switching the brakes on and off in quick succession.

Anti-lock braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better control than a driver could manage.

ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces for many drivers; however, on loose surfaces like gravel or snow-covered pavement, ABS can significantly increase braking distance, although still improving vehicle control.[1][2][3]

Since initial widespread use in production cars, anti-lock braking systems have evolved considerably. Recent versions not only prevent wheel lock under braking, but also electronically control the front-to-rear brake bias. This function, depending on its specific capabilities and implementation, is known as electronic brakeforce distribution (EBD), traction control system, emergency brake assist, or electronic stability control (ESC).

ABS, EBD, ESC/ESP, Airbags are very great safety features which could make a difference between life and death in emergency situation.
However Seatbelts has been proved to be most effective safety feature decreasing fatalities in an head on collision by upto 60% which is also quite high.. so even if the car has all the safety features don't forget to wear seat belts.

your brakes dont lock when braked and you can steer it also

Fiat's Dualogic is also AMT. IINM they are pretty troublesome : https://www.google.com/search?q=fiat dualogic problems site:www.fiatforum.com

What he was saying was that, contrary to popular belief that me and many other 'car noobs' believe in, manual transmission is better for the traffic conditions of India.

If you see the amount people abuse their cars in traffic - lugging their engines, starting from 2nd gear, slipping/riding clutches - an automatic transmission makes the best sense. Yeah you get lower FE. But the engine and clutch work you will need done eventually in a badly driven manual car will not be cheap either.

Damn you just took away my hope

I just thought everyone was a good driver like me.
I do agree that automatics will be a boon for the driver including me. I just hate how hard the clutch feels in my Palio after driving my sister's A-star(manual) for a few days. Not having to do anything will be even more awesome but I still believe that everyone should at least learn on a manual.
I get awesome average when I drive the A-Star while pathetic average when I drive the Palio. Reason is totally my driving. Personally I have started liking small, not so powerful cars as they are easier to keep under speed limits at top gear(read lower RPMs) and easier to maneuver in traffic.
Since I live in Chandigarh where bumper-to-bumper traffic is not that common, manual cars are easier to drive and good for the pocket. In other cities autos will be far better.

P.S. - I don't know why I changed this thread into my driving habits and opinions. Apologies for the OT.

Since this thread is about automatic transmissions, can anyone tell me how the 'automatic' transmission on the upcoming Maruti car works? How is it different from existing auto systems and why is its fuel efficiency not affected?

Just wanted to add to this...seems this AMT Maruti car will have both pure automatic mode 'D' as well as manual gear change (without clutch) is also possible. Can anyone confirm ?
I believe fuel efficiency would be better in manual cluthless mode than pure automatic.

I don't know specifically about AMT but in cars which are automatic and provide manual clutchless mode via paddle shifters, it is actually not fully manual. All it does is provide you with an option to downshift and upshift at will but it still will continue to upshift and downshift without your input in the manual mode as well.

^^ are you sure that 'upshift' is automatic? downshift has to be auto otherwise the vehicle would stall if driver forgets to change gears.

Well from what I have seen from the many car reviews in the last few days, in most of the cars even the upshifts are automatic. The so called manual mode only provides you with an option to downshift or upshift early at will and if you don't then it continues to do so on it's own as it would in the automatic mode.

P.S. - I have shifted to watching the many car channels available on Youtube these days instead of the regular English TV Series. Personal favorite these days is Tuned and The Smoking Tire both presented by Matt Farra.

 

[Criminal]

^^ i thought you'd driven one.

upshift is delayed till redline - that should help clear some doubts, the car will autoshift up/down but only after redlining..

 

[max_demon]

Yes, up shifts should also be automatic, else engine will be red lined every time one forgot to up shift

 

[Criminal]

upshift is delayed till redline ...

Yes, up shifts should also be automatic...

thanks! ok, then it must be delayed/automatic because it didn't happen with me.

Motorbeam put out a review of the Celerio : http://www.motorbeam.com/cars/maruti-celerio/2014-maruti-suzuki-celerio-test-drive-review/

you do however have to keep the pedal depressed at low speeds to prevent stalling in crawling traffic, specifically in first gear

The EZ Drive does make driving very convenient but is very jerky and you can feel the clutch being activated most of the time.

Although there is a creep mode mentioned which should have taken care of the stalling.

Our VBOX runs with both manual and automatic versions of the Maruti Celerio revealed the 0-100 km/hr time to be 15.05 and 15.60 seconds respectively

Doesn't look like there's much of a power loss, so FE shouldn't be hit.

 

[manu1991]

Would it still be jerky if you treat it as a semi manual and keep it on the +/- mode and manually change to neutral when the car is stationary?

 

[Criminal]

^^ don't know about Celerio, but on other similarly equipped cars, you don't need to shift to neutral when stopping momentarily.

 

[manu1991]

Yes I know. But in this case, since the reviews say that it is a bit jerky and ponderous while switching gears, i was wondering whether driving it treating it like a semi manual would eliminate some of these lags.
