In an interview with Automotive News, Fukuichi said that sedans are 'too formal and needs to be more dynamic'.
“Unless we can really offer a sedan experience you cannot have with an SUV or crossover, I think the sedan may not be able to survive if it does not evolve. At a certain point of time, the traditional, square, three-box sedan will go away,” he said.
He then went on to add that SUVs have improved a lot recently and are now as comfortable as sedans and handle just as well.
Also in the article, Fukuichi also hinted that there's a possibility that Lexus might create a Lexus wagon or a model with a shooting brake bodystyle if they had enough resources.
