First Test 2004 Lexus RX 330: The Segment Leader Holds Its Ground.
By Brian Vance
For Lexus, 2003 is the year of the SUV: the brand launched its GX 470 (MT January '03), and behind it comes a revised RX, now called the RX 330. This brings Lexus' sport/utility total to three, including the also-revised-for-'03 LX 470. The RX 300 often has been Lexus' best seller since its intro in '99.
Underhood is a new 3.3-liter V6 that ups the RX's output from 220 to 230 horsepower. Torque increases by 20 to 245 lb-ft. Teamed with a new five-speed automatic, the RX does the 0-60 dash in 7.8 seconds, almost a second quicker than its predecessor. Despite the newfound power, fuel mileage has increased from the previous model; EPA ratings are up from 17/23 to 18/24. An optional air suspension provides automatic ride leveling; four selectable height settings allow the driver to tailor ground clearance and handling characteristics.
Redesigned engine mounts, new sound-absorption material, and slippery aerodynamics make this RX nearly as quiet on the road as its ES 300 sedan cousin. For '03, improved safety features include additional airbags and optional road-following adaptive headlights that pivot as the RX turns. Handling has improved, thanks to a stiffer chassis and standard 17-inch wheels (18-inchers are optional).The new RX 330 will be the first Lexus built in North America (Canada), and we expect it to maintain a strong position in the mid-lux sport/utility segment.
Base Price: $35,000 (est)
Price as tested: $41,000 (est)
Vehicle layout: Front engine, AWD,
4-door, 5-pass
Engine: 3.3 L/230-hp V6,
DOHC, 4 valves/cyl
0-60 mph, sec.: 7.6
1/4-mile, sec./mph: 15.9 @ 86.9
Brk, 60-0 mph, ft: 122
600-ft slalom, mph: 57.10
On sale in U.S.: April 2003

USA Today Review of RX330
A peach of a crossover
You could think of the 2004 Lexus RX 330 sport-utility vehicle as a smaller, sportier cousin of the '04 Toyota Sienna minivan. Or you could think of it as distant relative of the Toyota Camry and Lexus ES 300 sedans. Or a luxurious iteration of the Toyota Highlander SUV.
All those models share drivetrains and key portions of their platforms, or underbodies — modified, of course, in size and specifics to suit each.
Those family comparisons would make the Lexus folks grumpy. They'd prefer that you think of the RX 330 as the new, improved, bigger, better, all-singing, all-dancing version of the vehicle that started what's become a rush into pricey, car-based SUVs generally called premium crossover vehicles.
By whatever name or description, the RX represents what automakers seek: the sweet spot where truck utility, minivan handiness and sedan agility converge in a package commanding high-profit prices.
Crossovers are compromises. They don't haul, tow or get through muck as well as good truck-based SUVs. They don't carry as much or as many as conveniently as minivans. And they don't really duplicate the responsive handling of a good sedan. But they come close enough for most folks.
The RX 330 was a peach in the test drive, with one, signal exception. The power assist on the steering faded in vicious, emergency swerves. That made it hard to turn the steering wheel for an instant.
That happened on the mechanically similar Sienna van, too. (Test Drive, March 21.)
Toyota engineers are investigating the problem. We'll assume Toyota will find and fix the flaw. And we'll hope the upgrade will be offered free to those who've already bought Siennas and RXs.
But we're going to move on to another issue: No third seat. "We don't think it needs one," says Mark Templin, Lexus vice president, because there are two other Lexus SUVs with third rows. Of course, the attentive shopper notes that the cheapest of them, GX 470, starts some $9,000 more than the RX price. Potential RX buyers don't want a bigger vehicle, with enough space for a well-designed third row, Templin says. Only one-third of them have kids younger than 18, Lexus studies show, so some logic is at work.
The test drive included a 400-mile ramble, mainly on major highways, through New York, New Jersey, Pennsylvania, Maryland and Virginia, plus another 100 miles in short-hop suburban jaunts.
The theme of the not-so-good things is crispness, or lack of it.
The body leaned a bit much in corners.
Brakes and steering felt slightly numb.
The automatic transmission paused too long between gears, especially on full-throttle downshifts. In those cases the RX first stumbled — almost as if the engine were cutting out momentarily, though that didn't seem to be happening — then lurched ahead when the transmission abruptly slammed into the lower gear.
All those would keep an enthusiastic driver from completely enjoying the RX. But none probably would bother the comfort-oriented folks the RX targets.
The RX 330 bristles with spiffy touches and major technology. The former include:
- A center console that slides far forward to increase legroom for a middle rider in the rear seat. No middle rider? Slide the console back to expose a floor tray for the driver's and front passenger's detritus. But don't set thin items, such as coins, on the tray. They slide back under the console when you accelerate. In fact, there's no good coin spot.
- Rear seats that continue to adjust fore and aft, a nice feature continued from the original RX 300, launched in 1998 as a '99 model. When full-forward, to expand rear cargo area a bit, legroom in back is scarce. The seats fold, of course, for maximum cargo room.
- A stubby, rubbery radio antenna atop the roof, where it attracts little attention and doesn't disrupt the flow of the styling. It folds for car washes.
- Roof rack crossbars that can be unlatched and slid from one side. No need to undo a catch on the other side.
The big-tech features:
- Headlights that swivel as the RX corners, for better illumination around the bend. The outside cover stays immobile; the inside bulb pivots. They're available only as part of a high-price package.
- True all-wheel drive that seems to work remarkably well. It splits power 50-50, front-rear normally, and can shift nearly all to either end, as traction needs require. The electronic traction control manages side-to-side wheelspin. Such electronic systems usually falter on steep, slick slopes and in other challenging conditions. You want to go, but the traction control, programmed to limit wheelspin, keeps trying to stop. Toyota appears to have tuned out that vile behavior, also a benefit to the AWD version of the Sienna minivan, which uses the same system.
- Optional adjustable suspension. It drops for easy entry and exit, raises to increase ground clearance, sits midway normally.
If you don't demand a third row, and prefer a cushy feel to the sporty tautness of, say, a BMW X5 — and if you aren't troubled by the power steering issue — you should find RX 330 a comfy charmer.
2004 Lexus RX 330
What is it? Remake of the vehicle that invented the premium, crossover sport-utility vehicle segment, larger and more powerful than its predecessor. RX 330 is a four-door, five-passenger, car-based utility vehicle available with front-wheel drive (FWD) or all-wheel drive (AWD). All are manufactured in Japan until September, when production begins in Canada.
How soon? Launched March 26.
How much? FWD starts at $35,600, including $575 destination charge. AWD starts at $37,000. Typically equipped, about $40,000. Expect to pay full sticker price, Edmunds.com says. Optional headlights that turn slightly as the vehicle does for better illumination around corners are available only as part of $5,455 Performance Package accessories group.
What's the drivetrain? 3.3-liter V-6, 230 horsepower at 5,600 rpm, 242 pounds-feet of torque at 3,600; five-speed automatic transmission.
AWD system splits power 50% front, 50% rear under normal circumstances, shifts power as needed to wheels with the most traction. System has no center differential and relies on traction- and stability-controls to shift power to wheels not spinning. Unlike many such systems, RX 330's (and the similar Toyota Sienna minivan AWD system) is tuned to keep wheels moving instead of stopping them in severe wheelspin.
What's the safety gear? Normal belts and bags plus driver-side knee air bag; front-seat-mounted, side-impact air bags; side-curtain head-protection bags for front and rear; anti-lock brakes with brake assist.
What's the rest? Anti-skid and traction-control systems; automatic, dual-zone climate control; AM/FM/cassette/six-CD stereo; leather-covered steering wheel; power steering, brakes, windows, locks, mirrors, seats; remote-control locks; trip computer; auto on-off headlights; outside mirror defrosters; auto-dimming mirrors; fog lamps; 225/65R-17 tires, alloy wheels with matching spare tire and wheel.
How big? 186.2 inches long, 72.6 inches wide, 66.1 inches tall on a 106.9-inch wheelbase. Weighs 3,860 pounds (FWD) or 4,065 pounds (AWD). Rated to carry 1,385 (FWD) or 1,180 (AWD) pounds, tow 2,000 pounds, or 3,500 pounds with tow package. Cargo space is listed as 38.3 cubic feet behind rear seats, 84.7 with rear seats folded.
How many? 75,000 a year.
Who'll buy? Slightly more women than men, probably married, about 45 years old, probably no kids, or none at home, with average household income of $125,000 to $150,000.
How thirsty? FWD is rated 20 miles per gallon in town, 26 on the highway. AWD is rated 18/24. Premium fuel (91 octane or higher) is recommended; regular (87 octane) is OK. Test AWD model's trip computer showed a best of 25.6 in highway driving, a worst of 15.6 in suburban jaunts.
Overall: A tauter, crisper driving feel would be welcome, and fix that power steering, for goodness sake, but generally marvelous for those who don't need three-row seating.

NCTD.com Review of RX330 (4 pages total)
Summary
Lexus calls the RX 330 an LUV for "luxury utility vehicle." We'll call it an SUV for "suburban utility vehicle." In many ways, a minivan has more utility, more room inside, more seats, and even, as in the new 2004 Toyota Sienna, four-wheel drive. But the RX 300 has more panache than any minivan, which may be perceived as too suburban.
That said, the RX 330 offers a good ride, a plush, innovative interior, ready power with an 18/24 mpg city/highway EPA mileage rating (4x4), and the confidence that all-wheel drive confers in winter driving, all with more room and, to some eyes, more elan than a simple sedan. Add Lexus quality and reliability and that all-important see-over-the-traffic seat height and it's your move, LUV.

Technologies of new RX330
Bells, Toys, and Whistles
by Jim Kerr
There is something to be said for a very basic vehicle that is easy to diagnose and work on. However, without advances in technology we wouldn't have features that make driving more enjoyable - such as electronic fuel injection, keyless entry systems and fantastic sounding stereo systems. Some technologies available on vehicles are not really necessary, but enhance our safety and enjoyment of the vehicle. I like to call those options "bells, toys and whistles".
One of the newest vehicles on the market has an abundance of these neat features. The Lexus RX 330 is a Luxury SUV and it is often luxury vehicles that are used to introduce new technologies. After the features become well accepted, they tend to migrate down to vehicles that are more economical. Take keyless entry for example. Not long ago this feature was exclusive to luxury vehicles. Now it is commonly found on most new vehicles. With this in mind, some of the options discussed today could be standard equipment on your next vehicle.
Several features found on the RX 330 can also be found on other makes as well. Rain sensing wipers are one of these features. The wiper system uses an infrared sensor mounted on the inside of the windshield near the rear view mirror. When the wipers are turned to delay mode and water hits the windshield, light is refracted differently into the sensor. The electronics inside the sensor turn the wipers on until the windshield is clear and then the wipers stop, waiting for the next drops of rain. This sounds like the ultimate in laziness until you have to drive in light misting rain. Then the benefits of being able to concentrate on driving rather than constantly operating the wiper controls become obvious.
Another neat RX 330 feature is the DVD-based navigation system. Navigation systems are available on many vehicles and I generally don't recommend them unless you have to drive in the U.S. or one of Canada's major cities. The mapping isn't great for many smaller cities, but the RX 330 uses the Nav system for other purposes too. With the added Rear Back-up Camera feature, drivers can see in the Navigation system screen areas behind the vehicle that are normally hidden from viewing in the rear view mirrors. The video camera isn't much bigger than a 35-mm film canister and is mounted above the rear license plate and I found the picture clear even after travelling down muddy and dusty roads.
DVD based rear seat entertainment systems are now available on many vehicles but the Lexus RX 330 has taken it one step further. Place the vehicle in park with the parking brake applied and the front seat Navigation system screen now becomes a second DVD movie screen. You could rent a movie and take the whole family out to your own driveway Drive-In movie!
Automatic levelling headlamps are available on a few vehicles equipped with High Intensity Discharge (HID) headlamps but again the RX 330 improves on the system. Not only do the headlamps automatically level, they turn in the direction the vehicle is moving. Called the Adaptive Front Lighting System (AFS), a central controller calculates the optimum light direction based on vehicle speed and steering angle. Turn left and the left headlamp beam will turn up to 15 degrees to the left. Turn right and the right headlamp beam moves up to 5 degrees to the right. The right moves less than the left because the right headlamp is already aimed several degrees right to help light up the shoulder of the road.
The system goes through a short test cycle when the key is first turned on, so to anyone watching, the RX 330 almost looks alive as the headlamps quickly dip and rotate.
A feature not found on the RX 330 but available on the Lexus LS430 and the new Toyota Sienna is Dynamic laser cruise control. A small transmitter below the front bumper sends out laser beams that are reflected off vehicles ahead. The vehicle-to-vehicle distance is calculated by a computer and if the distance is too short the computer will reduce engine throttle and even apply brakes if necessary.
Some features enhance our safety. Others are for convenience and comfort. Technology keeps on advancing and there are many other interesting features on other vehicles to look at in the future.

TruckWorld.com Review of RX330
Swiveling headlights, rain-sensing windshield wipers, laser-controlled adaptive cruise control, and an air suspension system are just a few of the high-end option features the luxury arm of Toyota has bestowed upon the new Lexus RX330.
Lexus' sleek new SUV is also hundreds of dollars cheaper than the RX300 that it replaces, which is a pleasant surprise in this age of ever-increasing prices.
Still, at $35,025 for the base front-wheel-drive model and $36,425 for the all-wheel-drive version, it's a chunk of change for a mid-size SUV in a market swelling with competition from all fronts.
Does Lexus have the right package to lure buyers to the RX330? The Truckworld.Com staff spent a few hours driving both front- and all-wheel-drive RX330s around the San Antonio, Texas, countryside to figure that out.
One of the first things that captured our SUV-oriented senses was the plethora of electronic wizardry found in and under the RX330's sleek, new body; technology that was designed, according to Lexus, to make it easier and more enjoyable to drive than the RX300, which debuted in 1999.
"Lexus customers expect any new technology to improve the driving experience, not to complicate or frustrate it," says Denny Clements Lexus group vice president and general manager.
The optional swiveling headlights are a good example of that mentality. Called the Adaptive Front Lighting System (AFS), a computer calculates steering angle and vehicle speed to determine the optimum lighting direction.
Then it swivels the headlights independently of each other to provide more light into turns. The left headlight can swivel as much as 15-degrees in a left turn while the right headlight stays centered. Turn right and the right headlight will rotate up to five degrees while its counterpart stays centered.
To further lighting, each headlight has a self-leveling feature that helps them maintain maximum lighting depending on the road conditions.
Pretty cool stuff that hasn't seen the light of day since Preston Tucker used a swiveling third headlight on his car in the late '40s and the French Citroen employed swiveling headlights on the DS model in the '60s.
What Tucker and Citroen didn't have were an on-off switch to disable the feature or a computer to balance and aim the headlights when the optional air suspension system is activated.
The air suspension is part of what Lexus calls the Performance Package option-a $5,455 add-on to the base price of either the front-wheel-drive or all-wheel-drive RXs. (The option, by the way, includes leather-trimmed interior, power tilt/telescoping steering wheel, one-touch moon roof, 18-inch graphite-plated aluminum wheels, 235/55R18 all-seson tires, sequential 5-speed automatic, power rear hatch, High Intensity Discharge (HID) headlights with AFS, and rain-sensing wipers.)
The air suspension has four modes--normal, low, high, and access-and is activated through the sue of air springs/shocks fed by a low-pressure air tank under the floor that's controlled by the vehicle's computer. In the "normal" mode the air supsneion automatically lowers the RX330's ride height by .3-inch when the speedometer hits 62mph. When the vehicle speed drops back below 50mph, the suspension returns back to its normal position. See signs of gravel road or rough ashpahlt, flip the suspension to the "high" position. It raises the all-wheel-drive RX330 by 1.2 inches, but it can only be activated when the vehicle is doing less than 30mph.
Flip the switch to "access" while idling or in Park and the suspension drops the ride height from its normal seven-inches of ground clearance to 5.9 inches. This inch of suspension drop makes it easier to load groceries or slip into those heated leather seats.
Feel a bit racy, slip the suspension into the "low" mode. The air suspension drops the ride height by .6-inch, which is said to improve handling while giving a more "sedan-like" ride.
All this sounds great, but we didn't see any real performance or driving advantages for the average Lexus buyer, other than knowing that its there, that would incline us to pay $1,000 dollars for the air suspension.
What we did find of real value, especially for those driving in the snow belt states, is the Vehicle Stability Control (VSC) that comes standard on all the RX330s. VSC uses sensors on the wheels to monitor front or rear wheel slide and compensates by using engine power and or braking to keep the vehicle on a steady course.
The all-wheel-drive RX330 adds to the control and traction equation with a new all-wheel-drive system that is simpler and lighter than the one used in the now outdated RX300.
Lexus engineers still employ a center differential to split engine power evenly front and rear during normal driving. But when wheel slip does occur, the RX330 uses the VSC system to divert power front/rear, or side-to-side instead of a viscous coupling, which is a bit slower and uneven in operation.
Another safety addition in the RX330 is front air bags supplemented with a knee air bag and side air bags. This combination wraps the front seat occupants in pillows of protection from the knees to the top of the torso.
Our brief driving experience did show that the newest Lexus is very car-like in its ride and handling. The AWD version weighs 4,065 pounds while the FWD model tips the scales at 3,860 pounds. Not a lightweight. Weight, coupled with a independent suspension at all four corners, gives it a soft, car-like ride, with a sharp kick in the rear when negotiating speed bumps or potholes.
Road and wind noise also caught our attention; we felt that even an entry-level Lexus SUV should be a little quieter. Some of the wind noise seems to generate from the roof rails and around the side mirrors. Small item, but one noted.
The saving grace is the seats are excellent as is the sound system and layout of the interior. The center console is easy to access and easy to use. The shift lever for the automatic is well-placed, and heavily notched gates slow down speedy shifts ensuring you'll find the right gear when you're in that sporty mood.
If you need to load the RX 330 with gee-whiz gear, opt for the navigation system ($2,350). It's great for those who are road atlas impaired.
You can also add the rear seat entertainment system, a little $1,840 investment that will keep those in the second row seat happy on long road trips. In fact, at one point we found ourselves engrossed in a Vin Diesel epic, watching the DVD on the roof-mounted flip-down screen and hearing the action through wireless headphones.
Speaking of seats, the RX330 is sans a third-row seat. Instead of following the leads of other "crossover" SUV brands that have mostly very uncomfortable third-row seating, Lexus opted to keep rear storage and second-row comfort maximized. We applaud the move.
We also applaud the smoothness of the 230hp 3.3-liter V6. It delivers better fuel economy than most mid-size SUVs with EPA estimates of 18 city / 24 hwy mpg for the AWD version and 20/25 for the FWD.
It does the on-ramp and passing tasks with relative ease, too, clipping 0-60mph times in the upper seven-second range. Not rabbit fast, not turtle slow. Just smooth and solid. The five-speed automatic is almost seamless, too, adding to a pleasurable driving experience.
In fact, this second generation RX is on the right track in numerous ways. It's four-inch-longer wheelbase and slightly larger body do make it a more comfortable ride than the model it replaces. Consider, too, the long list of options that provide upscale SUV buyers with a vehicle they can tailor to their own needs.
In all, the RX330 delivers what one would expect from an entry-level luxury SUV with the Lexus badge.
TruckWorld.com Review of RX330
Swiveling headlights, rain-sensing windshield wipers, laser-controlled adaptive cruise control, and an air suspension system are just a few of the high-end option features the luxury arm of Toyota has bestowed upon the new Lexus RX330.
Lexus' sleek new SUV is also hundreds of dollars cheaper than the RX300 that it replaces, which is a pleasant surprise in this age of ever-increasing prices.
Still, at $35,025 for the base front-wheel-drive model and $36,425 for the all-wheel-drive version, it's a chunk of change for a mid-size SUV in a market swelling with competition from all fronts.
Does Lexus have the right package to lure buyers to the RX330? The Truckworld.Com staff spent a few hours driving both front- and all-wheel-drive RX330s around the San Antonio, Texas, countryside to figure that out.
One of the first things that captured our SUV-oriented senses was the plethora of electronic wizardry found in and under the RX330's sleek, new body; technology that was designed, according to Lexus, to make it easier and more enjoyable to drive than the RX300, which debuted in 1999.
"Lexus customers expect any new technology to improve the driving experience, not to complicate or frustrate it," says Denny Clements Lexus group vice president and general manager.
The optional swiveling headlights are a good example of that mentality. Called the Adaptive Front Lighting System (AFS), a computer calculates steering angle and vehicle speed to determine the optimum lighting direction.
Then it swivels the headlights independently of each other to provide more light into turns. The left headlight can swivel as much as 15-degrees in a left turn while the right headlight stays centered. Turn right and the right headlight will rotate up to five degrees while its counterpart stays centered.
To further lighting, each headlight has a self-leveling feature that helps them maintain maximum lighting depending on the road conditions.

Lexus introduces RX 400h, world's first luxury hybrid SUV
Lexus has issued the following press release:
Lexus introduced what will be the world's first luxury gas-electric hybrid SUV today at a press conference at the North American International Auto Show. The RX 400h will be powered by a V6 Hybrid Synergy Drive system that combines sub-eight second zero-to-sixty acceleration with fuel-efficiency equivalent to the current average for a four-cylinder compact sedan. The RX 400h will also be rated Super Ultra Low Emission Vehicle (SULEV), one of the most stringent emissions rating in the industry.
"The new RX 400h re-defines the midsize luxury SUV market while raising awareness and acceptance of hybrid gas-electric vehicles among luxury car and SUV buyers," said Denny Clements, Lexus group vice president and general manager. "This is truly a breakthrough in terms of hybrid gas-electric powertrains because, for the first time, it adds a new performance dimension to the traditional hybrid advantages of high mileage and low emissions."
Lexus created the car-based, luxury SUV segment with the launch of the innovative RX 300 more than five years ago. For 2004, Lexus made significant enhancements to the luxury content, performance and safety features with the introduction of the RX 330, making this vehicle the perfect match for the new V6 hybrid system.
The RX 400h will be powered by a V6 Hybrid Synergy Drive system that combines sub-eight second zero-to-sixty acceleration with fuel-efficiency equivalent to the current average for a four-cylinder compact sedan. The RX 400h will also be rated Super Ultra Low Emission Vehicle (SULEV), one of the most stringent emissions rating in the industry.
The new RX 400h will become the premium model in the RX series, offering smoother and quieter operation, increased performance, significantly better fuel economy and a host of high technology, safety and comfort features.
Vehicle Dynamic Management
The RX 400h will introduce another industry first called VDM, or Vehicle Dynamic Management. Monitoring a variety of sensors, the system is designed to anticipate the onset of a vehicle skid or slide and then helps correct the situation with a combination of braking and throttle control. The new VDM system is less obtrusive than conventional VSC but ultimately more effective.
More Powerful, Advanced Drivetrain
The 400h hybrid powertrain combines a powerful electric motor with the highly efficient 3.3-liter V6 engine found in the RX 330 to significantly improve low to mid-speed acceleration and overall fuel efficiency. The system is a "full hybrid," meaning that the RX 400h is capable of operating in separate gas or electric modes, as well as a mode that combines power from both.
The RX 400h will develop a peak system output of approximately 270 horsepower and deliver combined fuel economy significantly better than the current average compact sedan rating of 27.6 miles-per-gallon. Zero-to-sixty acceleration will also improve over the current RX 330's sub-8 second time. The RX 400h with optional all-wheel-drive, which features a rear-drive electric motor, will accelerate quicker yet.
The RX 400h uses a regenerative braking system to further boost system efficiency. When the vehicle is coasting or the brakes are applied, the electric motor functions as a generator, capturing kinetic energy that would normally be lost as heat through the brakes and converting it into useable electricity to recharge the batteries.
One of the most remarkable features of the RX 400h is how similar this SUV is to its cousin, the RX 330. The computer-controlled powertrain seamlessly blends power from the V6 gasoline engine, the electric drive motor and the generator. The driver does not feel the vehicle changing operational modes. In fact, the only give-a-way is the absence of the traditional tachometer. In its place, the RX 400h has an illuminated power meter that displays the level of power generated by the gas-electric hybrid powertrain. The driver will also be able to monitor the gas-electric power distribution on the available seven-inch touch panel display screen that comes with the navigation system.
Luxury and Convenience Features
Lexus craftsmanship and attention to even the smallest details continue with the RX 400h. Nearly every feature available in the RX 330 is found in the RX 400h, with the exception of an exclusive RX 400h use of brushed aluminum accents inside that convey a high-tech look and feel to match its capabilities.
"We believe the RX 400h will exceed the expectations of luxury vehicle buyers and establish a premium market for performance-oriented, fuel-efficient gas-electric hybrids," said Clements.
Preliminary Specifications
Powertrain: Engine - 3.3 liter V6
Electric motor(s) - Permanent magnet
Estimated total horsepower - 270
Expected EPA emissions rating - Super Ultra Low Emission Vehicle (SULEV)
Transmission - Electronically-controlled Continuously Variable Transmission (ECVT)
Wheelbase: 106.9 in.
Length: 186.6 in.
Width: 72.6 in.
Height: 66.1 in.

Toyota's new hybrids
by Jim Kerr
Hybrid Synergy Drive. We first heard about this automotive hybrid powertrain design with the introduction of the 2004 Toyota Prius. The original Prius, launched in 1998 was also a hybrid, but the development of the second generation Prius included many advancements in hybrid technology and a powertrain concept well beyond the context of a single model line.
Just this past week at Detroit's North American International Auto Show, only hours after the Prius was named 2004 North American Car of the Year, Toyota demonstrated their commitment to producing ecologically compatible, comfortable, practical and fun to drive hybrid vehicles by announcing future Hybrid developments.
Toyota's 2005 Highlander will be the second Toyota vehicle and the world's first seven-passenger hybrid SUV to receive their Hybrid Synergy Drive powertrain. This mid size Sport Utility will be powered by a 3.3 litre V6 gasoline engine along with a larger capacity battery than the Prius that will deliver nearly double the power to an all new high speed electric motor. This new electric motor will operate at twice the speed of the Prius's 10,000 rpm electric motor and deliver more than twice the power.
Add the gasoline and electric motor together and the Highlander's horsepower is projected to be around 270 ponies. That power will move the Highlander from a stop to 60 mph in less than eight seconds yet still give fuel economy similar to a compact sedan. Driving range is estimated to be more than 1000 kilometres on a single tank of fuel. This hybrid will also meet the Super Ultra Low Emission Vehicle (SULEV) rating, the toughest in the industry.
Lexus will also receive a hybrid. The RX 400h is a luxury SUV to be built on the RX330 platform and like the Highlander will be powered by a 3.3 litre V6 engine and electric motor. These vehicles are "full hybrid" which means that they are capable of operating either in gasoline or electric mode as well as a combined power mode.
Drivers will notice the absence of the traditional tachometer. In its place, the RX 400h has an illuminated power meter that displays the level of power generated by the gasoline/electric hybrid powertrain. Gasoline/electric power distribution can be monitored on the standard 18 cm touch panel display screen, similar to the current Prius.
Optional all wheel drive systems will use an additional rear drive electric motor, providing even quicker acceleration. The additional motor also boosts system efficiency with its regenerative braking system. When the vehicle is coasting or the brakes are applied, the electric motor becomes a generator, storing energy in the battery that would normally be lost as heat in the brake rotors. I find it interesting that unlike conventional 4wd vehicles, this hybrid system not only improves acceleration even on good traction surfaces but is more efficient too!
Truck owners don't need to feel left out. Toyota used the Detroit auto show to unveil a concept vehicle - the FTX pickup truck. This concept is a preview of the capability of the next generation 2006 full size Tundra pickup. Peak under the hood of the FTX concept and you would find a large displacement V8 hybrid gasoline-electric engine with torque and power to haul those large loads yet deliver the fuel economy of a V6. While the next Tundra will not be a hybrid at the start of production, Jim Press, TMS executive vice president and COO says an optional hybrid powertrain "is under serious consideration down the line".
Even though Toyota was already planning future hybrid vehicles, the interest by drivers has (pleasantly) surprised them. The original Prius production plan for 2004 calendar year was 36,000 units.
Although the 2004 Prius just arrived at dealers in October, Toyota Motor Sales in the U.S. has already announced a 31 percent increase in production to 47,000 units annually of its all-new, second-generation Prius gas-electric hybrid sedan to help meet the vehicle's heavy demand in the market.
Toyota is working on fuel cell technology too, but hybrid technology is something we can build today and reap most of the benefits of green vehicles right now. Expect other manufacturers to increase their hybrid vehicle offerings too. Toyota has already announced licensing agreements with Nissan for use of the Hybrid Synergy Drive technology and it is rumoured that one of the "big three" will with Toyota too. It looks like there may be a lot of hybrids on our roads sooner than we thought.

The RX had some problems with the programming of the trans for some drivers in '03. It was not a mechanical problem. The dealers can reprogram the trans.
My wifes '04 RX330 has the drive by wire accelerator and it took some getting used to. My new 4R has the same system but the V8 has different programming for the trans.
