ARAI has clearly defined the parameters it tests the FE on: windows rolled up, no AC, no stereo, two passengers, city-highway mix etc. I think it's listed somewhere on their website.

all the figures are exact as published in ACI magazine, no typo errors here.

I just went back to the start of the thread and re-read GTO's award-winning review (well if it hasn't won yet it deserves to!) My old dilemma keeps popping back up. (http://www.team-bhp.com/forum/sedans...s-diesel.html) This time kept my mind open and focused on the diesel review as well. And know what? More and more am leaning in that direction! Spoke to a friend who has been through a Scorpio, Swift VDi and now Fortuner and he swears by diesel. And after nearly 20 years of handling manual trannies, am not sure an AT will keep the beast inside me happy!

About a week to go before the promised test drives materialise (I hope). Can't wait to TD the AT Petrol and the Diesel back to back- I guess that's the only way to resolve my dilemma now!

VW Vento petrol/diesel

• 0-60 kmph: 5.09/ 4.80
• 0-100 kmph: 12.18/ 11.30

Acceleration in gear:

• 20-80 3rd gear: 13.40 secs/ 9.24 secs
• 40-100 in 4th gear: 22.61 seconds/ 10.50 seconds

ACI figures for vento automatic petrol from september 2010 issue:

acceleration:

• 0-60: 6.09 seconds
• 0-100: 14.21 seconds

In gear acceleration:

• 20-80: 8.36 seconds
  
• 40-100: 11.04 seconds

No FE figures given for A/T.

In gear acceleration for Petrol Manual from 40-100 is 22.61 seconds and In gear acceleration for Petrol A/T from 40-100 is 11.04 seconds. Does this seem odd??? I think the Petrol Manual figure is too high.

Did the AT change gears?

40-100 (and 30-80) figures for an AT are in 'kick down' mode and they are not 'in gear'. That is the reason they look impressive then manual figures.

Looks very odd. What will be the engine RPM at 50kmph in 4th gear - for Petrol Vento? Any idea - anybody? That can answer the question.

How can we have "40-100 in 4th gear" (for that matter any specific gear) reading, for an AT? Does not make sense to me. Can any body explain?

Hi Chethan,
In the new honda city AT, with the paddle shifters you can be in a specific gear, but speed should be more that the lowest speed allowed for that gear, so testing 40 - 100 in 4th and 20 - 80 in 3rd is possible in the anhc, similarly I guess, the vento too has a manual mode (not paddles) which makes this possible, but not sure.

It is not in 4th gear. The minute you start accelerating hard (while cursing at 40 kmph, probably in 4th) AT is going to downshift.

Thanks!!

In that case - timing should be the same for both AT & MT - Is it not? Unless the gear ratios are different.

Are the gear ratios different?

Even though the manual modes are there in ANHC and Vento, the acceleration figures are recorded in automatic mode.
30-80 and 40-100 are in 'kick down' mode
Even if driven in fully manual mode using paddles/triptronics, the figures will not be the same as manual since automatics are heavier by 60-70 kg and torque converter robs some energy.
Yes, gear ratios are different as well.

So, both can not be directly compared. But still, "40-100 in 4th gear: 22.61 seconds" is very high. Power & Torque development curve would be useful here.

- Is it ABS+EBD or standalone ABS? If it is standalone, is it a 4 channel one?
- 2-Din System - is it a standard 2 DIN size?.

1. All modern ABS units are 4 channel.
2. DIN is a standard. The n in german means 'standard'

+1. Thanks Guna. That clarifies the confusion in my head. Maybe a typo on the post or in ACI.
But as Chethan says, petrol figures are quite high. How do these numbers compare with similar in- gear details for comparable cars - in this instance ANHC?
Hope this is not OT.

Sir, Mahindra Scorpio comes with a 3 channel ABS system without EBD and Brake assist.
