Autocar understands that the ES will come to the UK as the replacement for the GS, which is to be discontinued this month.
The ES has been around since the Lexus brand's inception in 1989, but the seventh-generation model will be the first sold here. The car is 4.8 metres long, the same as the GS, and will serve as a rival to the BMW 5 Series.
The single image posted online today follows the confirmation of the new model earlier this month, when Lexus released a preview image of the car's nose and large front grille.
The ES's angular body panels and sharp lighting features mimic styling applied to the larger LS.
More details on the car are expected at Beijing show next week. The image was only accompanied by the words: "Engaging design, athletic performance, and renowned refinement transform Lexus’s most popular saloon."
