If there is any part of this car that could be called a quantum leap, it's the interior, which is much more together, more modern, and more fully equipped than any previous Lexus ES interior.

It starts with the standard SmartAccess key fob and push-button engine starting, a first for the ES, and goes from there. The instrument panel and center stack are completely new and much more driver-centered, engaging and involving that previous panels. The main instruments are deeply tunneled, using white LED lighting and the Optitron electroluminescent displays that are part of all Lexus models, with their eye-pleasing startup routine. The standard trip computer monitors a dozen functions. All of the real wood trim is from a matched set that is serial-numbered for future replacement, if necessary. The thick, fat steering wheel is a pleasure to use.

There's more space overall, within a few cubic feet of the original LS 400 V8 rear-drive sedan at 95.4 cubic feet, with more shoulder and leg room built in, and the rear floor is flat and can accommodate large American feet under the seats. There are three interiors to choose from in leather, perforated leather, or cloth, plus optional semi-aniline leather.

The new ES is insulated well. At cruising speeds, it's extremely quiet, in part due to a new acoustic-control laminated windshield.

The driving ambience is superb, with good sightlines, the hooded instruments and crisp graphics, a 10-way power seat and standard tilt/telescope steering wheel. Fit and finish inside are exemplary.
