I'd say that Mr. Ratan Tata had a vision that he was able to do everything what other manufacturers did at a later stage. There are examples like:
1) Safari TCIC
- Small engine with a turbocharger; now everyone doing it. While at the time the car was launched, everyone used to plonk only BIG engines for BIG performance.
2) Sierra Turbo:
Hell, that thing used to do 160 kph in 90's. A proper 5 seater SUV it was at that time and was well suited for urban environment.
Other companies will also launch their crossovers with time. XUV AWD is already one.
4) Indica(V2, Turbo and DICOR):
First diesel and BIG hatchback of India. Tata recognized the possibility way ahead of others.
Hatch+Boot; look when Tata did this and when others.
6) Indigo CS:
World's first compact sedan.
All these cars were a bit ahead of their time IMO
. And their cars always had an everlasting design appeal... err.. I love Aria at heart and I am biased here.
