Note: This post is not to bash any brand
There are always two type of manufacturers. One is engineering driven (like many European and American brands) and one is technology driven (Japanese, Koreans etc). There is a third category which has none and hence we won't talk about them.
Tata cars are more or less biased towards the engineering driven side and this is even more evident on their new products like Storme, Tiago, Zest, Bolt etc. These are well engineered products with some touch of technology, normally slightly better built cars are these and they won't have so called impact protection jugaads highlighted like Suzuki TECT etc. They basically have a heavier chassis and normally weigh more.
In other words, Tiago seems to be a well engineered product and I won't be surprised inncase Tiago manages to get even 4 star safety rating. Why so? Involvement of JLR teams in development and their feedback as well as the taut chassis with a good kerb weight, maybe Tiago can prove to be the safest small hatch in our country.
