A good move indeed. However, i feel the step should have been taken long back. IMO Grande should be relaunched with decent interiors, and a new engine (may be a detuned Safari one), to hit the markets hard.
I somewhat agree with you SUMO OR NO SUMO until TATA replace VICTA completely with GRANDE and position it against BOLERO, changing names won't help matters for TATA.But for some reason people percieve that changing name would enhance its sales figure,perhaps they believe in this phrase a little bit more than you and me:"PERCEPTION IS FINAL REALITY".
True. Sumo was a very popular and legendary brand name in the automotive sector of India and no doubt, that it will be thoroughly missed. Here is one my favourite TV Commercials of Sumo which used to air long back.
