Lexus has trademarked the ‘UX’ name in Australia including that for the UX 200, UX 250 and UX 250h variants. The ‘X’ in the name hints at a new SUV to join the luxury brand’s NX, RX and LX models. But what kind of SUV will it be?

AutoGuide thinks that the UX name is a perfect fit for a new seven-seat SUV that is rumored to arrive in American showrooms late this year, likely to be an elongated RX. Such a car will compete with the likes of Acura’s new MDX, the Infiniti QX60 and the Audi Q7.

But Autoevolution argues that the powertrain sizes suggested by the model names are too small for a large seven-seat SUV, and UX could turn out to be a small crossover to slot in below the NX, which is a rival to the BMW X3 and Mercedes-Benz GLC.

The Lexus UX could even share basic underpinnings with the new Toyota C-HR (pictured above) – a striking compact crossover that has the Nissan Juke, Mazda CX-3 and Honda HR-V in its sights – just like how the Lexus NX borrows basic architecture from the Toyota RAV4. Based on the three variant names, the UX could get naturally-aspirated 2.0 and 2.5 litre engines, as well as a hybrid drivetrain.

The SUV market is red hot now, and Lexus would do well to strike it repeatedly while it remains so.
