Q. Between Baleno having BS VI and Tata Nexon BS IV, should I wait for Tata Nexon BS VI If Yes when it is expected? At present I am continuing Alto 2004 Model registration extended by 5Year due above reason sharp and valuable suggestion would be quite appreciable.

BSVI of nexon might get launched in mid of 2020 but I will suggest you to go with BSIV model because after BS6 price of cars will increase with 10-15% cost and Tata Nexon BSIV is a superbly designed and refined engine its a very good and value for money compact SUV, It better than Baleno in everything. Performance, Power, features, design, build quality, comfort with best suspension in the segment, an amazing ground clearance of 209mm with hill assist, and the safest car in India with 5 star NCAP safety rating. Go for Tata Nexon you will not regret XZ+ variant is best option and if low on budget XM variant is best.

Doesnt really matter whether its BS4 or BS6.Go for the right car.
