The ES is built on what Lexus refers to as the K (G-AK) platform, which is a rebranded version of the Toyota New Generation Architecture that underpins most new Toyotas. The ES is built on the longer wheelbase once shared with the now-discontinued Avalon.

The new ES is fronted by the latest iteration of the Lexus “Spindle” grille, with the rest of the car resembling a cross between the previous-generation ES and the previous LS super- luxury sedan. The cabin is fronted by a dashboard featuring a small gauge pod containing a  speedometer surrounded by a tachometer and flanked on one side by a fuel readout and the other side by a temperature indicator. The top centre of the dash is dominated by a large info screen, which is controlled but an infuriating touch-pad that is too distracting to be used in a car. The cabin style on the luxury themed models, is both elegant and visually calming. The cabin design of the F Sport trims is carefully assembled but is not overtly luxurious compared with the sumptuous cabins of the non-sporting models. While the front seating position seems tighter than it is in the related Camry, there is abundant legroom up front and in the rear, and the seats are very comfortable.

The ES is available is a mind-bending number of variants including 2.5L hybrid and V6 engines combined with front-wheel drive a normally-aspirated 2.5L four that sends power to all four wheels. Generally, price bumps to move from one trim to another, are in excess or far in excess of the value of the additional content.

Predicted reliability is above average. Servicing costs are low for the luxury segment.
