2006 TOYOTA 4RUNNER Review - Base Price $27,635
Tougher look reflects trail-worthy capability.
Introduction
The Toyota 4Runner has been face lifted for 2006, and now comes with more luxury and convenience equipment than ever before. But it's still the real deal, a traditional sport utility built on a truck chassis, thoroughly capable on truly rugged terrain.
The 4Runner is no car-based crossover station wagon. It's built on a rugged ladder frame with a solid rear axle. While some consider this design dated when compared to the latest SUVs or CUVs, which use unit body construction and independent rear suspensions, the 4Runner's more traditional design offers better recreational capability and long-term durability.
Yet the 4Runner does not ride like a buckboard wagon. Toyota engineers went to great pains to prove that this durable, adventurous configuration need not compromise everyday comfort and convenience. The 4Runner is quite comfortable around town and on the highway, with a nice ride quality, almost luxurious. An optional linked shock-absorber system called X-REAS further improves handling in sweeping, high-speed turns. Active safety features include ABS, EBD, Brake Assist, traction control, and electronic stability control, all standard.
Though the basic design may be relatively traditional, the 4Runner features the latest in off-road electronic technology, including Hill Start Assist and Downhill Assist Control. Having the 4Runner walk you down a steep, muddy incline with both feet off the pedals is an impressive display of technology and engineering. Both full and part-time four-wheel drive is available, but even the full-time system comes with a locking function for when the going gets sloppy. Add that stuff to its highly capable suspension, and the 4Runner will go just about anywhere any other production vehicle will go.
Whether you choose the standard V6 or the newly revised V8, the 4Runner offers responsive performance. The V8 boosts the 4Runner's tow rating to 7,300 pounds. Both engines benefit from a sophisticated variable-valve setup and drive-by-wire throttle, delivering strong, responsive acceleration out on the highway; the V8 was revised for 2005 for vastly improved performance. Both engines also benefit from a five-speed automatic transmission.
The 4Runner is noted for its quality construction, durability and reliability. Look up QDR in the automotive dictionary and you might see a picture of a Toyota 4Runner.
Inside, the 4Runner is roomy and comfortable. An optional third-row seat expands the passenger capacity to seven, but the seat can be folded or removed for cargo space. The optional GPS navigation system includes a rear-mounted video camera that lets the driver back to within an inch of the vehicle behind when parallel parking and can help the driver spot a small child before backing up. The navigation system on 2006 models features voice activation. Bluetooth technology has been added for 2006 as well, and a factory-installed rear-seat DVD entertainment system is now available.
For 2006, the appearance of the 4Runner has been revised. Grille, bumpers, and light clusters are re-styled for '06, as are the overfenders and lower body cladding. New trim provides more visual distinction among the SR5, Sport Edition, and Limited grades. For 2006, the 4Runner benefits from upgraded upholstery and more features.
While it may seem old-school to people who want an all-weather sport touring vehicle, the 4Runner is the hot setup for outdoor enthusiasts for its ability to carry them and their gear down primitive roads, rough two-tracks, serious mud or sand, and rugged terrain. Yet it won't punish its owner in everyday use. It's smooth and quiet and highly sophisticated in terms of technology and features. If your weekend involves driving over rugged terrain, the 4Runner is an excellent choice.
Interior
The Toyota 4Runner cabin is a good place to be in rugged terrain and nasty weather. For starters, it's roomy and comfortable. It's highly functional. The quality of materials and they way they fit together is good, and loaded models are quite luxurious. Overall, the 4Runner cabin looks traditional SUV, in spite of some high-zoot features.
The standard cloth is nice, and the cloth seats in the SR5 and Sport Edition are comfortable, with side bolsters to keep the driver in place when cornering or driving off road. All seats offer adjustable headrests and three-point seatbelts, and the driver's seat adjusts eight ways, manually on the SR5 V6 and powered on all others. The driver and front passenger sit up high, as one expects in an SUV, yet flatter to the floor, as in some low cars like a Ford Mustang. The driver's legs stretch out, rather than down, toward the pedals. It's a feeling we've noticed in some Jeeps, going back quite some years, and it's the side effect of a very practical SUV impulse to pull the ground clearance up as high as possible while keeping the overall profile low for stability.
A two-tone dashboard houses the instruments. Gauges illuminate orange, set in three deep binnacles that prevent the front-seat passenger from reading them. The fuel gauge uses an inclinometer for accurate readouts when the 4Runner is tilted in the rough.
Automatic climate control is standard on all models, while the Limited comes with his-and-hers dual-zone temperature controls. The fan, airflow and temperature controls, are big and easy to locate; they are long on design and a little awkward at first, but become easy to use with familiarity.
The stereo buttons are easy operate. The Auto down button for the power windows is illuminated but the central lock button is not and can be difficult and awkward to find in the dark, leaving impatient, would-be passengers tapping on your window as you fumble around for the switch, a daily annoyance. A display located just above the climate controls reveals time, ambient temperature, and trip data. A 115-volt AC power outlet is available, a real bonus in the backcountry.
An unusual feature is a pair of small convex mirrors at the rear corners of the interior, designed to help the driver see approaching vehicles when backing out of a parking space. The mirrors work on the same principal as those big convex mirrors mounted at the corners of large parking garages. In the 4Runner, they help the driver detect motion in a busy parking lot. Using them effectively, however, takes some practice, as it's hard to distinguish details. We're guessing most people don't use them.
The rearview video camera works incredibly well. A video camera hidden in the rear bumper projects the image onto the seven-inch navigation screen on the center dash whenever the 4Runner is in reverse. The pictures are sharp, even in complete darkness (with the backup lights on), and cover the area directly behind and a couple of feet on either side of the car. The extreme fish-eye view of the lens makes distances difficult to judge, but skilled drivers quickly learn how to use it to their advantage. When parallel parking the camera allows the driver to easily back to within an inch of the car behind. The camera adds safety by giving the driver an opportunity to see what's immediately behind the 4Runner, whether it's a short metal pole or a child on a tricycle or someone pushing a grocery cart.
The navigation system is among the best, intuitive and relatively easy to use. It features a touch-screen monitor, voice guidance and Bluetooth capability. Toyota says that its route-searching capabilities are more than twice as fast as competitive systems. Map data for the contiguous United States and major cities in Canada is stored on one DVD. The integrated Bluetooth feature provides a hands free communication system using a cellular phone; calls can be dialed by using the navigation screen's keypad, while calls can be received and ended by pushing a button on the steering wheel. The system is integrated into an eight-speaker JBL AM/FM/CD stereo, which is automatically muted when a call is received. The stereo speakers then act as the phone receiver and transmitter.
The ultimate stereo system is a 360-watt JBL Synthesis setup with 10 speakers and controls integrated into the steering wheel. Standard on SR5 and Sport Edition is a six-speaker AM/FM/cassette/CD stereo with MP3 and WMA capability. An all-new universal mini-jack port connects to most portable music players.
New for 2006 is an optional rear-seat DVD entertainment system with a nine-inch screen and wireless headphones, available on all three trim levels.
Getting into the back seats to watch it, however, is a little more challenging than in a sedan. The rear doors provide a relatively narrow opening, and you have to duck your head to get in and out. Once in, however, the second-row bench seat is roomy for two. The seat is raised slightly in the center position, so the middle passenger sits on this uncomfortable hump. Better to fold down the wide center armrest and enjoy its two cup holders and its tray for French fries or whatever. An unusual feature, but perhaps a good idea, is a small trash bag holder for rear passengers. The rear ventilation ducts that bring comfort in the form of warm or cool air are more easily appreciated.
The optional third-row seat adds an element of flexibility. It's actually two separate seats that fold up to the sides of the cargo compartment, parallel to the rear side windows. These seats are easy to stow, and access from the curbside rear door, via a spring-loaded sliding mechanism on the second seat, isn't too difficult. But even large children, like a healthy 11-year-old, will sit in these rear seats with knees pressed up toward the chest and hair brushing the headliner. And the third-row seats take up cargo space even when folded. Fortunately, it's not too difficult to remove them for maximum cargo volume. But drivers who need to seat seven on a regular basis would be better off with a Sequoia, Highlander or Sienna.
Cargo space is designed well. The second-row seats can be folded down with the headrests in place, though we sometimes found it easier to pull them off before flipping the seat bottoms up and the seatbacks down. The seat folds nearly flat, flatter than a Ford Explorer's, and the seatbacks are reinforced to support heavy loads. The cargo area includes structurally attached steel tie-down hooks in the floor, with additional hooks on the sides. A clever double-decker rear storage shelf helps organize cargo in two levels. Using just one hand, the collapsible shelf can be folded flat or lifted up easily. When deployed, it's rated a sturdy 66 pounds. A large storage box is provided on the right side of the cargo compartment. Storage bins are provided in all four doors, and every seat gets a cup holder.
The rear hatch comes standard with a power rear window that can be operated from the key fob. If it senses a small hand in the way, the window reverses directions and opens. (Don't try this at home.) The hatch itself also has a power opener, which is great when running up with an armload in nasty weather. An electric power-close function sucks the hatch shut and ensures secure sealing without slamming.
An overriding impression when we climbed out of the 4Runner was its quietude. Rugged it may be, but the lack of road, driveline or ambient noise in the cabin is impressive, given its off-road capability. Wind noise is all you'll hear if you turn the stereo off.
Walk-Around
Back when Toyota pickup trucks were sleek and compact, the 4Runner looked like a sleek, compact wagon (with extra ground clearance) based on a Toyota pickup. All that changed when the current-generation 4Runner arrived in 2003, or at least the sleek-and-compact part did. While still clearly related to a Toyota truck, today's 4Runner is big and burly. It only looks small in relation to Toyota's even bigger Sequoia.
Styling changes for 2006 add still more visual muscle. The trapezoidal grille remains, but now it slashes into the bumper below; and one big, bold horizontal crossbar has replaced the two slimmer bars used previously. Foglights, when ordered last year, were contoured to the surface of the bumper; now they are standard, and they hunker down in squared-off foxholes. The more massive and bumpy front bumper sets a chunkier theme that continues through more prominent overfenders and body cladding (making the 2006 model an inch-and-a-half wider than the '05). Headlights and taillights have been more subtly re-shaped, with the teardrop effect of the former slightly exaggerated.
More than ever, the 4Runner looks off-road rugged and ready to hit the dusty trail. Backing up that contention are skid plates for the engine, transfer case and fuel tank, all of which come standard. (Even 2WD models get the engine and fuel tank plates.) A molded-in step adds a functional look to the broad rear bumper.
Visual cues help distinguish among the three trim levels. Bumpers are body-color on all three models. On SR5, however, grille, door handles, and the license-plate trim are chrome, and running boards are painted black. The Sport edition retains the hood scoop and is further distinguished by a smoked-chrome effect in its grille and headlamp trim, and by a graphite-and-black roof rack. Tubular side steps replace the SR5's running boards. The Limited looks almost military with its body-color grille, black roof rack and black running boards (which are illuminated). The standard aluminum-alloy wheels have six spokes on SR5 and Sport Edition; five on Limited, and they grow from 16 inches to 17 to 18 as you move up the line.
4Runner's windshield, side windows, and side mirrors are made of hydrophilic glass and repel water like a waxed car or a window that has been treated with Rain-X. The glass causes water to form large drops, which are quickly shed by gravity or wind. The side mirrors are angled out to increase the driver's field of view. The available moonroof includes a two-stage wind deflector designed to reduce wind noise when traveling above 55 mph.
Impressions
The Toyota 4Runner's standard 4.0-liter V6 engine is responsive, and never left us feeling short changed. This engine is packed with the latest technology, including fully variable valve timing, a linkless electronic throttle, and lightweight all-aluminum construction. It's rated at 236 horsepower and 266 pound-feet. (Those figures are down slightly over last year because of revised SAE testing procedures; the engine performs the same as it did in 2005.) The 4WD model attains a credible 17/21 mpg City/Highway EPA rating, while the 2WD V6 is rated 18/21 mpg. Premium fuel is recommended for optimum performance. We heartily recommend this engine for anyone who doesn't plan to do much towing.
The optional 4.7-liter V8, introduced for 2005, represents a huge improvement over the V8 it replaced. We found it delivered strong performance for our 2006 4Runner. It's smooth and tractable and never struggles when thrust is needed. The V8 features variable valve timing with intelligence (VVT-i) and electronic throttle control with intelligence (ETCS-i), turning it into a real performer. It's rated 260 horsepower and 306 pound-feet of torque, and adds about 190 pounds to the weight of the vehicle. EPA fuel-use estimates are 16/20 mpg for the 2WD V8 and 15/19 with 4WD. Toyota recommends premium fuel. Both engines feature a cranking system that keeps the starter engaged until complete combustion is achieved, freeing the driver from holding the key until the engine turns over. This is a feature usually associated with expensive luxury sedans.
Both engines are paired with a sophisticated five-speed automatic transmission. More gears means better response for any given situation along with better efficiency. The transmission is equipped with Artificial Intelligence Shift control, which changes gear-shifting patterns according to driving conditions and driver intent. It works well and seems to understand when you want to cruise and when you want to get with the program, and it shifts smoothly around town.
The 4Runner handles very well for a truck with a live rear axle. We drove all the models over twisting back roads along the Oregon coast and found them easy to drive at a quick clip. We also spent a lot of time in a 2006 Limited 4WD V8 around Los Angeles. The suspension damping is excellent. When the road got bumpy, we could tell our truck had a solid rear axle rather than an independent rear suspension, but the 4Runner still handles more confidently than other live-axle SUVs, such as the Chevy TrailBlazer. Rack-and-pinion steering gives the 4Runner quick response and good steering feel.
The ride on unpaved roads is smooth, which is important on long gravel treks over washboard surfaces. The 4Runner's well-tuned damping and progressive-rate spring bumpers are to thank here. Where the 4Runner really comes into its own, however, is when the terrain gets truly gnarly. There's lots of suspension articulation for climbing over boulders and gullies, and a host of technology for handling steep, slippery grades.
Still, the 4Runner is a truck, not a car. Rather than using unit-body construction like the Toyota Highlander and RAV4, the 4Runner is built on a separate ladder frame that features full-length box-section frame rails. Toyota also steered away from using an independent rear suspension like the one on the ladder-frame Ford Explorer. An independent rear suspension would have offered better ride quality and allowed for a roomier interior, but Toyota said off-road capability was a high priority for the 4Runner and that its live rear axle provides more suspension travel.
A limited-slip differential, optional on many SUVs, is standard on even 2WD 4Runners. We found the two-wheel-drive models impressively capable on rugged terrain; indeed, a 2WD 4Runner is more capable off road than many all-wheel-drive SUVs. For ultimate traction, however, you do need a four-wheel-drive model; and it seems to us that if you don't need four-wheel drive, then perhaps you should not be looking at 4Runners though it is a good highway vehicle.
V6 4WD 4Runners are equipped with Toyota's Multi-Mode shift-on-the-fly system, which incorporates both a two-speed transfer case and a Torsen-type limited-slip center differential. The driver can shift between 2WD, 4WD High, and 4WD Low. The Torsen center differential allows the use of 4WD High in all types of driving conditions, and on all types of roads, from dry to wet to snow-covered. The system gives the 4Runner a sure-footed feel because power is applied to all four wheels. But the center diff can also be locked out for military-truck-grade traction in extreme slop.
4Runners with the V8 and 4WD come with what Toyota calls a full-time system, but it operates much less like a car or crossover-style all-wheel-drive than it does Toyota's own part-time system with the 2WD mode removed. A Torsen center differential distributes torque 40 percent front / 60 percent rear under most conditions and changes the ratio as needed based on steering input and wheel slip. It automatically shifts to 29/71 front/rear during steering maneuvers to enhance tracking through the curve. If the rear wheels should spin, however, the center differential can shift the ratio to 53/47 to control the slippage. And again, it can be locked out completely when the going gets extreme.
All 4WD 4Runners come with Toyota's Downhill Assist Control (DAC) system, which controls the speed when creeping down steep, slimy grades. Shift into 4WD Low, check to make sure DAC is activated, pull to the edge of the nearest precipice, take your feet off the pedals, and steer your way slowly down the trail. Once you make the leap of faith that comes with allowing the machinery to do the work for you, Downhill Assist works very well and is easy to manage. The antilock brakes make a noisy "dunk, dunk, dunk" sound as the system lowers the 4Runner safely down the slippery slope. Gently touch the gas or brake pedals to slow or speed your progress, then take your feet off the pedals again, and the system comes back on: "dunk, dunk, dunk, dunk." DAC helps keep the 4Runner pointed in the direction you steer it, using ABS to curb the tendency for the vehicle to get sideways on steep descents. The system will work continuously for three minutes (because the brakes will heat up with prolonged use), but Toyota officials say it only needs the shortest of breaks to continue. Three minutes is usually more than enough time to get to the bottom of the sort of extreme descent we're contemplating here.
All 4Runners, 2WD and 4WD, come with Hill-start Assist Control (HAC), which is designed to prevent the vehicle from rolling backward or slipping sideways when starting off on a steep ascent. The system uses the brakes to stop an individual wheel or all wheels, whatever it takes to keep 4Runner running forward.
The optional rear air suspension offers improved ride and performance when towing or hauling heavy loads. The air suspension automatically adjusts the ride height according to vehicle load. The driver can also manually raise the rear suspension when driving off road to increase the ground clearance and improve the rear departure angle. This latter feature is useful in the extreme conditions, but most owners will never go there.
X-REAS improves handling dynamics on the road with no compromise in off-road articulation or travel. X-REAS reduces the tendency of the vehicle to bob up and down in corners and improves handling by damping body pitch and roll. A simple system, it links the shock absorbers diagonally through hydraulic lines (e.g., the front left shock is linked to the rear right shock). A central control damper helps keep the system in balance.
Anti-lock brakes (ABS) with Brake Assist and electronic brake-force distribution (EBD) come standard on all 4Runners. The four-channel ABS prevents the wheels from locking under severe braking, improving driver control. The 4Runner's ABS uses an off-road algorithm to improve stopping performance in slippery conditions, a great feature. EBD automatically balances the braking force front-to-rear for shorter stopping distances. Brake Assist helps a driver who may not be pressing the brake pedal hard enough during an emergency stopping situation by maximizing braking power regardless of the force on the pedal.
Overall, we found that 4Runner's brakes worked well. They felt a bit sensitive on the V8 models, and were a little challenging to modulate for limo-smooth stops, but owners will quickly adjust to this.
The 4Runner's fuel tank was specifically designed for off-road use. The tank is plastic, offering better protection against corrosion, rust-through and connection leaks. Yet the plastic tank is armored by a steel case for protection against debris kicked up by the tires, or against the rocks off-highway enthusiasts might encounter.
Summary
The Toyota 4Runner is a highly capable trail vehicle. It will get you over the rocks and through the muck, but it won't make you regret its durable construction when you're cruising the Interstate. It's smooth and quiet on the road and there's plenty of room for family and friends. The V6 is our first choice for its power and efficiency, but the V8 delivers excellent response and is the proper choice for towing. If you want serious recreational capability with quality, durability and reliability, the 4Runner is an excellent choice. On the other hand, if you rarely venture onto unimproved trails, then you'll find the Toyota Highlander and car-based SUVs smoother and more comfortable.
