You are spot on that vehicle weight
alone doesn't have a direct correlation with safety. There are vehicles that weigh less than one ton which have a 5* Euro-NCAP rating. Then there are vehicles that weigh two tons or more which would get a 0* if tested by Euro-NCAP.
And yes, it's quite possible to reduce the weight of non-chassis components alone, and this wouldn't affect safety at all. The Japanese are the masters at weight reduction, no doubt!
The Nissan Micra is already a case study when it comes to reducing weight. It's based on the contemporary, safe Renault-Nissan alliance's V platform. Nissan engineers went to great lengths to reduce the weight of each and every component in the car without affecting safety. The end result - they were able to easily achieve a 4-star rating on the Euro-NCAP for a 915 kg car that's larger in size than its weight suggests.
Here is my concern. If Nissan already did so much to reduce the weight of the Micra, then how could they reduce the weight of the non-safety critical components alone by such a great extent (~ 125 kg or so)? Of course, getting rid of many features, using thinner seats, smaller wheels and tyres, single wiper, omitting the glovebox lid, rear wash-wipe and NVH package etc. can indeed reduce the weight without affecting safety.
But they have already done many of those things on the Micra Active. Yet, it weighs 900 kg when compared to 915 kg for the original Micra. One can safely assume the 15 kg weight difference is solely due to the omission of features and using thinner seats etc. So one can conclude that the Micra Active is as safe as the Micra/Pulse.
Could one say the same of the Go which should weigh around 125 kg less? The Go does have even less features than the Micra Active and has more cost cutting, such as the missing glovebox lid, insulation etc. but can these alone add up to
that much of a difference in weight?
Again, it's possible to reduce the weight of each and every non-safety critical component. But how much more can they do on a car that has already gone through the brilliance of Japanese weight reduction techniques? It's also possible that they could use extremely light but strong components as in sports cars (such as composites, carbon fibre, suitable alloys etc.) to reduce the weight further without affecting safety. But it would push up costs to stratospheric levels and would they do this on a basic, low-cost car?
That's two crucial unanswered questions. The third is NCAP safety rating. Since the Datsun Go would not be sold in Europe, it wouldn't go through Euro-NCAP. But what about ASEAN-NCAP or Latin-NCAP which use older, somewhat less stringent Euro-NCAP standards? Will Nissan/Datsun get an ASEAN-NCAP rating for the Go, as India does not even have an NCAP or equivalent?
Please understand that these are
only my concerns, as stated in the previous comment. In
NO WAY am I suggesting that the Datsun Go is an unsafe car, not at all! In fact, I think the
Datsun Go would be safer than the cars it would be competing against, as it's based on the contemporary, 4-star Euro-NCAP achieving Nissan Micra platform as opposed to much older platforms for its competitors.
I merely wanted to know if the Go is going to be
as safe as the Micra/Pulse/Micra Active. If Nissan/Datsun can prove through independent NCAP testing that it is just as safe (or comes very close), then it would be a fantastic achievement indeed!

Thus, I would risk seating in the front row (have enough experience of Ambassador Taxis in Kolkata) than in the last cramped row of a seven seater. |
Ah! Those old Ambys - it's indeed an experience to be seated as the front middle passenger on those, either comfortably as a child, or uncomfortably as an adult, with both arms stretched out wide on the front seat back behind the driver and the other front passenger.
Only then could the poor chap (who is already seated at an awkward angle) use the gear lever and steering comfortably.
Yes, the third row on many vehicles is a joke. It's usually highly uncomfortable for anyone other than kids, but at least it's safe there, with proper three-point seatbelts.

M800 (yes, it's still on sale in BSIII cities) or Alto800? There is no way this car is going to be priced in the range of the M800. It's not fair to expect a modern (but basic) car based on the (relatively) large, thoroughly contemporary Nissan Micra platform with a 1.2 lit. engine to be priced close to a smaller, three decades old car with an 800cc engine (which has the honor of having brought modern motoring to India and having put the country on wheels, literally).
If you meant Alto800, I kind of agree. The Micra Active already competes against cars like the Wagon R and i10 on price, despite being from a sub-segment above. So the Datsun Go should logically compete on price against the Alto800, Alto k10 and Eon, even though it's clearly larger than all three.
