The popularity of SUVs means that nearly every carmaker has at least one city off-roader in its range. Now Renault has joined the fray and given its smaller Captur a big brother in the form of the Kadjar, the result of the French company's cooperation with Nissan. The Kadjar is a Nissan Qashqai crossover, so it has a lot of the Qashqai's technology in it. That has certain advantages, since the Qashqai's in its second generation, and its technology has been tried and tested.
