The new generations of Lexus LS and Lexus ES will debut in 2018 and 2019 respectively.

The driving tests of the early prototype of the new Lexus sedan have been launched in the U.S. The new model can turn to be the prototype of the next generation of Lexus LS and Lexus ES models. The latter went on sale four years ago.

The new Lexus sedan will get a more exquisite design of body in L-Finesse style. It will also slightly grow in size due to the expanded wheelbase. Toyota New Global Architecture (TNGA) platform, on which the latest generation of Prius is built, will serve as its basis. Modern six-cylinder engine may appear under its hood, CarPark reports.
