Lexus introduces the RX 400h hybrid luxury SUV.

officials say the added electric makes the RX 400h hybrid in acceleration than its traditional sibling, the RX 330.

Starting in 2005, Lexus offers the luxury crossover sport-utility with gasoline-electric hybrid

Based on the top-selling Lexus RX the new, 2006 Lexus RX with a V6 engine, three motors and all-wheel drive out reduced smog-forming emissions and qualifies as a Super Ultra Low Vehicle in California.

In addition, a city/highway fuel economy of 28 miles a gallon for the Lexus RX is akin to the average for new compact these days and means the 5-passenger vehicle could more than 450 miles a fill-up.

Actual driving depends on driving habits, conditions, weather and terrain, other things, of course. But on the RX 400h fuel economy is 44 percent higher than the combined government fuel rating for Volvo’s 2005 SUV with a 5-cylinder engine, and 51 higher than the 18.5-mpg fuel economy rating for a BMW X5 SUV with 6-cylinder engine. also 33 percent better the fuel economy rating for a RX 330 with a V6.

The RX 400h won’t be the SUV the best fuel economy in America, however. This belongs to the 2005 Ford Hybrid. which has a combined of 33.5 mpg for a two-wheel-drive model. The Hybrid has a 4-cylinder internal engine.

But the RX 400h is entering the as the best V6-powered SUV in fuel with a government rating of 30 mpg in the and 26 mpg on the highway.

The vehicle’s quick acceleration is likely to attract buyers. to instantaneous torque at startup electric motors, the RX 400h from 0 to 60 miles an hour a half-second faster than its RX 330 sibling, according to Lexus. The performance for the RX 400h is what reports for the 0-to-60-mph performance of its ML500 SUV—with a V8.

And at least one car magazine reported their RX posted a 6.8-second 0-to-60 mph This is the kind of time Mercedes reports for its V6-powered Sport Sedan .

Intriguing of Buyers

The RX 400h will a new era in luxury vehicles, predicted Clements, Lexus group president and general manager.

He the leather-appointed vehicle with conveniences such as standard tailgate and navigation system as as an SUV-like 83.9 cubic of cargo space could to people who have disposable but want to make a statement their social consciousness compromising what they in a vehicle.

The RX hybrid is likely to incremental sales to Lexus our research shows we’ll get who haven’t thought about before, he added.

Still, studies over the years shown that well-to-do typically rank fuel a low priority when they a purchase. And Clements said is going to need time to see how large a market there is for a hybrid SUV.

Starting suggested retail price at is more than $48,000, is far pricier than the more $37,400 MSRP on the top RX 330 with engine. Company officials the hybrid RX 400h includes $6,000 in standard features, as navigation system, that are on the traditional RX. The price also a $4,000 to $5,000 premium for the technology.

Even at that price, early indications were the RX would be in demand. Lexus it had at least 9,000 pre-sold for a vehicle whose total volume to the U.S. is expected to be 24,000.

This is significantly pre-launch volume and activity we have ever had this for any vehicle in our 15-year history, said.

Technology Taken to Level

The hybrid technology in the RX can be thought of as a scaled-up and more version of the Hybrid Synergy system that’s in Toyota’s car, which ranks as the gasoline-electric hybrid in the world sales in excess of 110,000.


The which has a starting manufacturer’s retail price of just $21,000, has been on sale in the since the 2000 model and has attracted a noteworthy clientele, actors Cameron Diaz and diCaprio as well as comedian Crystal. Toyota Motor owns the Toyota and Lexus

But where there’s one main motor for motive power in the mated to a 4-cylinder engine, are two electric motors for motive in the RX 400h, and this larger and vehicle has a V6. Indeed, the RX 400h is the V6-powered hybrid sold by or Lexus in the U.S. Honda selling a V6-powered midsize Hybrid sedan in calendar

Generally speaking, gas-electric maximize the efficiency of onboard sources—in this case, a V6 that’s the same configuration as the V6 in the RX as well as the electric motors.

The of the electric and internal combustion is controlled by electronics in the vehicle. The RX has the latest, fourth-generation control which operates more than the predecessor—used in the Prius—and is to make the transitions of power as as possible.

In the RX 400h, the electric motor up can drive the wheels with or the internal combustion engine With the V6 working, for example, the motor power might engine power when the is passing another on a highway. the engine off, the electric all by itself might move the from a stoplight. The rear motor in the RX 400h kicks in the system detects a need for traction.

The motors derive power from a 288-volt hydride battery pack rests under the rear The battery pack is recharged as the travels, either by energy during braking or by energy by the internal combustion engine. is no need to plug in the electric of the RX 400h.

Note that the RX V6 puts out a maximum 230 horsepower, the RX 400h’s engine puts out horsepower, due primarily to intake and changes. Torque is lower, at 212 lb-ft at 4400 rpm vs. 242 lb-ft at rpm. But when the electric power output is figured in, horsepower rises to a usable

The 0-to-60-mph time is improved in the RX from the RX 330 because torque is immediately in an electric motor. The electric motor in the RX 400h can 247 lb-ft of torque between 0 and rpm.

The only transmission for the RX is a continuously variable unit uses two planetary gears to the power to the wheels and gear the motor speed for increased

Drive It Like Other

Obviously, what’s most to drivers is they don’t to change the way they drive.

The RX looks much like a RX, with dimensions nearly except the overall length is by an inch and height is up by 0.3 inch.

The placement of the hybrid’s battery pack, aft of the driver means there’s a bit different dynamics when the vehicle is at the extremes, but most drivers likely to get to that point.

are likely to notice, however, how it can be to tell that the RX 400h is on. The startup can be subtle, especially if the combustion engine doesn’t on.

There’s a large display in the middle of the that can show, via an automated where the power for the RX 400h is generated and where it’s as the vehicle travels. It’s a graphic to the one in the Prius. There are information screens available one that shows fuel use and economy as the vehicle travels.

Odds and Ends

Besides the two motors that drive the there is a third motor works primarily as the starter to the as well as a generator. The RX 400h not have a traditional starter, or serpentine belt under the

Electrically generated power comes on so quietly, riders hear outside noises they don’t notice in a that derives all its power an internal combustion engine. So engineers updated the RX windshield special acoustic material.

early hybrids, the RX 400h not wear small, low-rolling-resistance Standard tires on the RX 400h are 18-inchers, and while they maximize fuel economy, do provide a stable ride officials said, referring to the that low-rolling-resistance tires known for the grip and traction more traditional tires This was a conscious decision, to between performance and fuel said David Hermance, engineer for environmental engineering at Technical Center USA Inc. We to take the fuel economy

The RX 400h’s all-wheel drive for off-roading. Officials warn the controls won’t let the electric burn out as you try to power up rock or slog through mud. As a the RX 400h had best be thought of as an SUV for off-road travel, such as on dirt paths.

The RX 400h about 300 pounds more the comparable RX 330. The extra comes from the battery electric motors and extra

If properly fitted, the RX can tow up to 3,500 pounds. This is the tow rating that the RX 330 has.
