Although Uyttenhoven didn't provide any more details about the CT's possible replacement, the LF-SA concept from the 2015 Geneva motor show could provide some clues as to the look of a new sub-NX crossover.
Launched in 2011, the CT shares its platform and hybrid drivetrain with the previous-generation Toyota Prius.

Lexus has a good record with its SUV models. According to Uyttenhoven, Lexus sold 652,000 cars globally in 2015. Almost half of those were crossovers, with sales split fairly evenly between the NX and larger RX. This year, the company is projecting that it will find new homes for about 200,000 RX models and 170,000 NX SUVs.
Last year, the brand sold around 10,000 CT hatchbacks in Europe. That's a drop in the ocean, with roughly 750,000 vehicles sold in the market segment that includes the Audi A3, BMW 1 Series and Mercedes-Benz A-Class.
In Australia, just 720 CT hybrids were sold throughout 2015. Accounting for 4.1 per cent of the luxury-small-car segment, the CT trailed the market-leading Audi A3 (5443), Mercedes-Benz A-Class (3629) and BMW 1 Series (2307).
