Call it sibling rivalry, two sides of the same coin, or whatever else that signifies two of a kind. It might not seem like it on the outset with the Datsun Redigo and the Renault Kwid looking so drastically different. But underneath, these are essentially the same car: same engine and gearbox, same platform and even the same suspension and tyres. The Kwid of course is better equipped but the Redigo is cheaper. So, if you wanted to spend less than Rs 5 lakh on the road for a reasonably well specced, citycentric car, which one should you go for?
