Hybrid Luxury Driving Performance - Lexus RX 400h Hybrid Overview

Hybrid Luxury
Driving Performance
While hybrid vehicles have become known for "exceptional fuel economy, "
for the RX 400h, Lexus engineers had the goal of creating a new type of hybrid
that delivered the highest levels of "luxury driving performance. " The result was
the first hybrid that delivers the acceleration of a powerful gasoline V8 engine.
In fact, the "400" in RX 400h stands for the power output of the 3.3 L engine
and hybrid battery which, when combined, approximate the power of a
4.0 liter V8 engine.
The RX 400h versus the competition
The RX 400h can deliver smooth V8-like acceleration in performance driving
conditions or it can deliver economy in economy driving conditions, while complying
with very clean Super Ultra Low Emission Vehicle (SULEV) tailpipe emissions
standards. You can choose performance driving by simply pressing on the
accelerator. Choosing to maximize economy driving with the RX 400h, or other
vehicles, involves many factors. Please see "Ten tips for improving fuel economy" on
page 7 of this booklet for details. Comparing the ratings of the RX 400h with V8-
powered luxury SUVs highlights the versatile capabilities of the Lexus hybrid system.
