Lexus Introduces RX 400h, the World's First Luxury Hybrid SUV

Lexus today announced the launch of the all-new 2006 RX 400h, the world's first gas/electric hybrid-powered luxury vehicle, which will go on sale in April 2005. Based on the best-selling RX 330, the RX 400h delivers greater performance, improved fuel efficiency and significantly reduced emissions while sacrificing … nothing.

The first mass production luxury vehicle to feature hybrid technology, the RX 400h incorporates a Hybrid Synergy Drive system that combines the 3.3-liter V6 engine with a high-torque electric drive motor-generator, plus a rear electric drive motor-generator to provide on-road all-wheel drive capability.

With a combined system output of approximately 268 horsepower, and more significantly, 3,500 lb.-ft. of axle torque at launch, the RX 400h delivers rapid acceleration with unexpected fuel efficiency.

At 7.3 seconds, acceleration from zero to 60 mph is about 0.5 seconds quicker than the RX 330 and better than many V8-powered competitors. The RX 400h's estimated EPA combined fuel economy rating of 28 mpg matches the average for new compact sedans and marks a 33 percent improvement over RX 330 AWD.

It also gains a 67 percent edge over RX 330 in city fuel economy. And its estimated EPA city fuel economy rating of 30 mpg exceeds most V8 and many V6-equipped luxury SUVs by over 100 percent.

"The RX 400h will open a new era in luxury vehicles, setting a new benchmark for luxury SUV performance and environmental compatibility," said Denny Clements, Lexus group vice president and general manager.

"It's truly a breakthrough in terms of hybrid technology because, for the first time, it adds an enhanced performance dimension to the widely known hybrid advantages of excellent fuel mileage and low emissions."

The new RX 400h will become the premium model in the RX series, adding numerous standard features that are offered as options on the RX 330. The seamless power delivery of the hybrid powertrain will be another plus for the RX 400h, because it will feel even smoother than conventionally-powered vehicles. The RX 400h will be rated as a Super Ultra Low Emission Vehicle (SULEV) in California (Tier 2 – Bin 3 in other states), one of the most stringent emissions ratings in the industry.

Externally, the RX 400h differs in subtle ways from the RX 330. The RX 400h features a revised grille, a new front fascia with additional air intake, sporty round fog lamps, unique 18-inch alloy wheels and LED tail lamps. Inside, brushed aluminum accents replace wood trim, and a power meter replaces the tachometer. The RX 400h will also include struts with internal rebound springs and linear control valves and feature specific suspension tuning for sportier handling.
