There are a fair few reasons to like the latest RX. For a start, the interior is attractive and comfortable, helped by the absorbent ride and generous standard equipment. CO2 emissions are pretty low for the class as a whole, so your company car tax bill shouldn’t be too horrific. The RX should prove very reliable, too. However, the Audi Q7 remains our favourite luxury SUV by offering a plusher interior, more passenger space and a better infotainment system.
