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 is also likely to attract Thanks to instantaneous torque at from electric motors, the RX goes from 0 to 60 miles an about a half-second faster its non-hybrid RX 330 sibling, according to The 7.3-second performance for the RX 400h is Mercedes-Benz reports for the 0-to-60-mph of its 2005 ML500 SUV—with a V8.

And at least one car enthusiast magazine their RX 400h posted a 0-to-60 mph time. This is the of time that Mercedes for its V6-powered C320 Sport .

Intriguing Group of Buyers

The RX will open a new era in luxury predicted Denny Clements, group vice president and manager.

He said the leather-appointed with modern conveniences as standard power-operating tailgate and system as well as an SUV-like cubic feet of cargo could appeal to people who disposable income but want to a statement about their consciousness without compromising they need in a vehicle.

The RX is likely to bring incremental to Lexus because our research we’ll get people who haven’t about Lexus before, he

Still, automotive studies the years have shown well-to-do buyers typically fuel economy a low priority they make a purchase. And said Lexus is going to time to see just how large a there is for a luxury hybrid

Starting manufacturer’s suggested price at introduction is more $48,000, which is far pricier the more than $37,400 on the top RX 330 with gasoline-only engine. officials said the hybrid RX includes some $6,000 in features, such as navigation that are options on the traditional RX. The also includes a $4,000 to premium for the hybrid 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.

on the outside are so mild they’re noticed by observers. The changes a revised grille and fog lamps, diode taillights, new badging and wheels.

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. (Remember, the RX 400h can go a certain on electric power only.) So a might need to check the ready light is on in the instrument after turning the key. indicates the vehicle is ready to go.

bother to look for a tachometer. don’t really provide information in hybrids, where is mixed and matched among So, the RX 400h has a power meter in the cluster instead.

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.

Lexus didn’t remove any features from the hybrid of RX. Indeed, a couple are updated. For the RX 400h has a new, more stability control system to prevent skids, and curtain have a new sensor that the bags if it detects a possible not just if the vehicle is struck in a crash.

Odds and Ends

the two electric motors that the wheels, there is a third that works primarily as the to the engine as well as a generator. The RX does not have a traditional alternator or serpentine belt the hood.

Electrically generated typically comes on so quietly, could hear outside that they don’t in a vehicle that derives all its from an internal combustion So Lexus engineers updated the RX with special acoustic

Unlike early hybrids, the RX does not wear small, tires. Standard tires on the RX are P235/55R 18-inchers, and while don’t maximize fuel they do provide a stable experience, officials said, to the fact that low-rolling-resistance aren’t known for the grip and that more traditional have. This was a conscious to pick between performance and economy, said David executive engineer for environmental at Toyota Technical Center USA We chose to take the fuel penalty.

The RX 400h’s all-wheel isn’t for off-roading. Officials the electronic controls won’t let the motors burn out as you try to power up ledges or slog through As a result, the RX 400h had best be of as an SUV for light off-road travel, as on non-rigorous dirt paths.

The RX 400h weighs about 300 more than the comparable RX The extra weight comes the battery pack, electric and extra reinforcing.

The gearshift has the usual Park, Reverse and gears, but there’s no indent for or second gear. Instead, the can be shifted to B for regenerative braking, allows the driver to choose to assign braking energy to the pack. But a driver also can let the electronics take care of the activities, which occurs the shifter is left in Drive.

If fitted, the RX 400h can tow up to 3,500 This is the same tow rating the RX 330 has.

The hybrid system, includes battery and control is warranted for eight years/100,000 whichever comes first. is in addition to the overall vehicle of four years/50,000 miles and a warranty on the V6 that’s good for six miles.
