If you think they do not have anything to do with each other, you are very mistaken, because they do. Although they will probably be very different in appearance when they reach the production lines, they will be very similar from underneath, once they are supposed to share the same platform, B0.
The B0 platform is a simplified version of the B platform, the same one used by Renault Modus and Nissan Tiida/Latio. In other words, both platforms can be built in the same plant with minor differences, so much that they look so similar only a specialist could differ one from the other.
This is why Nissan Livina has been recently presented in Brazil. The South American country already produces Logan and Sandero, badged as Renault vehicles, instead of Dacia. Since Nissan did not have a Brazilian produced car, only a truck, Frontier, it has seized the fact that the B0 platform is already in use in Brazil and have built there its first car. But it will not be the last.
Dacia Duster has been eagerly expected because it anticipates the small SUV that will be produced and probably launched in Brazil. The world premiere must even be in this country, as it has happened with Sandero. This is because Ford has been the first company to present a small SUV in Brazil, called EcoSport. It uses the previous Ford Fiesta platform and sells like hot cakes because it is the only option available in South American countries with that price tag. Renault clearly wants a piece of this market. Apparently, Nissan also does.
Since Duster's production version will be produced in Brazil, Qazana's may be built there as well. It would be something easy and fast to do, offering a car that perfectly fits a market segment that keeps increasing its share. And all this in one of the only car markets of the world that has not been heavily affected by the finantial crisis. Doesn't it sound sweet?
Both cars have different sizes, what may give the impression they do not share the same platform. Duster is 4.25 m long, 1.50 m tall, 1.64 m wide and has a wheelbase of 2.80 m. Qazana, on the other hand, is 4.06 m long, 1.57 m tall, 1.78 m wide and has a wheelbase of 2.53 m. Some means say it will use the new A platform that will be applied to the next generation Micra, but since the current Micra uses the B platform, we keep our bet that Duster and Qazana will have the same platform. We may be wrong, but we don't think we are.
Keep on comparing the two concept cars below. They may be look different, but they will surely be siamese twins.
