Do let us know what exactly a small car buyer desires!

If you were to choose between an i20 diesel (airbags, ABS, but poor braking distance) and Swift diesel (no airbags, ABS, decent braking distance), would you actually put your money on the Swift diesel?
Under certain driving conditions, like in a ghat section, even if you slow down quickly because of good brakes, you can still have an accident because the other guy might have been slow to react. That's when the airbags help.
Having a car that has good handling (high speed manners, sharp chassis etc) can also help avoid accidents.

Also in case of the i20 it is a know -ve that the diesel has the worst braking distance in the range, and the petols are better. It may be due to the engine weight up front being higher for the Diesel engine and the resultant weight distribution effect on all four wheel.

Diesel engined cars don't have engine braking apparently. Do a Google search for "Engine braking diesel". Quoting from Wikipedia -
Quote:
Diesel engines do not technically have engine braking in the above sense. The reason is that unlike petrol engines, diesel engines vary fuel flow to control power rather than throttling air intake and maintaining a constant fuel ratio as petrol engines do. As they do not maintain a throttle vacuum, they are not subject to the same engine braking effects as petrol engines are. |

Surprising since i have found the i20 to have lesser turbo lag than the polo 1.2D. |
The gearing ratio also affects the acceleration figures - not just the turbolag. For example - Linea diesel takes around 15 secs to hit 100 kmph from standstill. Now although Punto 90 HP is lighter and has Linea's engine, it takes 16.2 seconds to hit 100 kph.
ROUND NO. 2 - HANDLING
Having a strong performance only helps in a straight line. However, if for some reason you want to race your hatch on a track, you will need a car that handles well too. A car that handles well naturally enhances driving pleasure on our highways.
To get the ranking of best handling hatchbacks, I have used Team-BHP reviews on handling for each hatchback.
Guidelines For Better Ranking In Handling:
- Good high speed stability on highways. Should not feel nervous at high speeds.
- No bodyroll during cornering
- All FWD cars understeer, but good ones delay the onset of understeer allowing you to push harder on ghat or hilly roads.
- Good grip levels.
The ranking of hatchback with best to not-so-great handling characteristics - the one in the top gets 36 points and the one at the bottom get 1 points - looks like this:

Comments:
- Most tall boys have poor handling characteristics. There are a few exceptions like the Ritz though.
- Maruti A-Star and Chevrolet Spark surprise.
The ranking of cars with the best mix of performance & handling:

When we compare the Nano with the Jazz and everything else in between, we find out how good the A-star really is when it comes to performance & handling. Although the A-star costs just Rs. 4 - 5 lacs, it beats the pants out of majority of cars when it comes to these two parameters.
Now if we had just compared A-star with other entry level cars like Nano, Alto, Santro, Spark etc, it would have topped the list yes - but you wouldn't have known how good it really is when compared to the next car in the list. In this type of comparison, the more the merrier.
All one has to do is "blank out" Polo, Punto and all other hatches that one is not interested in buying from the final table. Just look only at the relative rankings/points of the cars one is interested to buy.
Tata Nano is at the bottom of the list and that seems to be unfair - but really - performance & handling are not exactly the USP of the car. It's real strengths (Practicality, price, running costs, looks etc) will show up in the rankings - even with the presence of Polo, Figo, Swift etc in the comparo.
