When the first Toyota
4Runner sport utility vehicle (SUV) was launched back in 1984, it was a
revolutionary new vehicle based on the mechanics of the
four-wheel-drive Toyota pickup truck. The 4Runner combined the
versatility and go-anywhere ability of four-wheel-drive with the
comfort and utility found in passenger cars.
Twenty-five years, four generations and more than 1.5 million
sales later, the 4Runner continues to evolve while remaining close to
its roots. The all-new fifth-generation 4Runner is even more rugged and
athletic, and packed with more power and better mileage. A completely
redesigned interior and unique cargo area make the newest 4Runner
smarter, more comfortable, and more versatile than ever.
More rugged than the Highlander and more versatile than the FJ
Cruiser, the 4Runner combines the toughness and durability of
body-on-frame construction with multi-use design that excels at a wide
variety of tasks.
The
2010 Toyota 4Runner is taller, wider and longer and is
available in a variety of configurations. It will be offered in three
models, top-of-the-line Limited, a well-equipped SR5, plus a Trail
grade for those who require maximum off-road capability.
Drivetrain configurations include rear wheel 4x2, part-time 4x4
and full-time multi-mode 4x4 with a locking center differential. All
4x4 models are equipped with a 4.0-liter V6 mated to a five-speed ECT-i
automatic transmission. The 4x2 models will be equipped with either a
2.7-liter four-cylinder engine mated to a four-speed ECT automatic or
the 4.0-liter V6 with the five-speed ECT-i automatic. Optional
third-row seats allow for up to seven-person capacity.
Exterior Styling
The design strategy for the new 4Runner emphasizes a more rugged,
powerful stance. Large diameter wheels and tires were added to not only
improve off-road performance, but also enhance the 4Runner's
truck-based characteristics. In addition to its styling emphasis on
ruggedness and outdoor adventure, the new design utilizes a combination
of Toyota's classic boxy form and progressive styling.
All 4Runner grades feature rugged new bumpers and wider shoulders,
with newly designed head- lamp and tail-light systems, which offer a
newly-minted, technical design quality and better nighttime
performance. The front ends square fender flares meld with a muscular
profile that links with a beefy and square rear bumper and back door.
Aluminum alloy wheels are 17-inches in diameter on SR5 and Trail
grades and 20-inches on the Limited, and include a full size spare.
New Engine Choices

The 2010 4Runner is powered by a new 4.0-liter V6, which now
generates 270 horsepower and 278 lb-ft of torque. Through the use of
advanced engine management that includes dual independent Variable
Valve Timing with intelligence (VVT-i), the new 4.0-liter engine offers
the best of both worlds, adding more power while improving efficiency.
For 2010, the new V6 engine produces 34 horsepower more than the prior
V6, and 10 horsepower more than the optional V8 of the previous
generation.
Additional mileage improvements have come from careful attention
to wind flow, reducing aerodynamic drag to a Cd of 0.365. EPA-estimated
mileage improves from 16 city and 21 highway to 17 city/23 highway for
the 4x2, and from 16 city and 20 highway to 17 city/22 highway for 4x4
models. Both achieve an EPA-estimated 19 mpg combined, an improvement
of more than five percent. With the new 4.0-liter engine, maximum
towing capacity is 5,000 pounds.
In addition to the upgraded V6 engine, a proven 2.7-liter
four-cylinder engine with VVT-i is available on the 4x2 SR5 model. The
gutsy DOHC, 16-valve 2.7 makes 157 horsepower and 178 lb-ft of torque.
Mated to a four-speed automatic transmission with 2.80:1 first gear and
0.753 overdrive 4th, the 2.7 delivers 18 city/23 highway mpg.
4x4 Capability Designed-In
To build on its tradition of rugged body-on-frame construction,
the newest 4Runner shares the same platform as the FJ Cruiser.
Extensive frame and body reinforcements have been added, using
high-tensile materials to add strength without adding weight. SR5 and
Trail 4x4 models have a two-speed lever-operated, part-time system with
neutral position, while the 4Runner Limited is equipped with full-time,
four-wheel-drive with a locking center differential and employs a
three-mode, center console-mounted switch. The new 4Runner is also
equipped with a stronger rear differential over the previous model,
thanks to a gear ring that has increased in size from 7.87 to 8.18
inches.
To enhance grip, the A-TRAC system is now standard equipment on
all 4x4 models. The system can distribute driving force to any one
wheel in contact with the ground, making terrain irregularities and
slippery patches transparent to the driver. An electronic-locking rear
differential is standard on the Trail grade. Axles house 3.73 gears, or
4.56:1 with the 2.7-liter engine and the differential housings have
improved seals for better resistance to mud and water.
An array of advanced features, formerly only available in the Land
Cruiser, further boosts off-highway capabilities. The Trail grade
offers Toyota's Kinetic Dynamic Suspension System (KDSS) as an option.
KDSS radically improves terrain-following ability by disconnecting
stabilizer bars to allow for more axle travel, and better suspension
articulation in slow, difficult terrain.
Toyota's Crawl Control (CRAWL) feature is standard on the Trail
grade. CRAWL is an adjustable electro-mechanical system that can be
tuned to match the terrain by selecting any of five speed levels. The
system maintains an appropriate speed that keeps the vehicle under
control and minimizes the load on drivetrain and suspension components.
The CRAWL feature helps make traversing difficult terrain easier and
safer. With the transfer case shifted into low range, Crawl Control
regulates engine speed and output (along with braking force), to propel
the vehicle forward or in reverse at one of the five low-speed
settings. This allows the driver to maintain focus while steering over
very rough level ground or steep grades, without having to also
modulate the throttle, or brake, pedals.
The Trail grade also features a Multi-Terrain Select system which
allows the 4x4 operator to dial in wheel slip control to match the
terrain. In loose terrain such as mud and sand, more-than-normal wheel
slip is permitted, allowing wheel-spin to work in the vehicle's favor.
On bumpy moguls, or solid rock, wheel slip is minimized and the system
acts more like a limited slip. The Mogul setting is for any extremely
uneven terrain, such as V-ditches, slopes, and ridges, uphill or down.
All 4Runner 4x4 models are standard-equipped with Downhill Assist
Control (DAC), which is designed to augment the low-speed ascending
ability of low-range by holding the vehicle to a target speed with no
driver intervention. All V6 4Runner models come standard with
Hill-start Assist Control (HAC), which provides additional control for
off-road driving by helping to keep the vehicle stationary while
starting on a steep incline or slippery surface.
On-Road Driving Dynamics
The new 4Runner may be a truck-based SUV, but it offers the kind
of drivability and riding comfort more often associated with car-based
platforms.
Coil springs over gas shocks are used at all four corners for a
comfortable ride and controlled handling. A double-wishbone independent
front suspension, combined with new, variable-flow rack and pinion
steering, makes for precise control on demanding roadways. The
four-link rear suspension minimizes rear axle hop and assures a smooth
ride for back seat passengers.
The Limited grade comes standard with an X-REAS suspension system
that further improves performance, comfort and control. X-REAS
automatically adjusts the damping force of shocks when driving over
bumpy surfaces, or when cornering. The system uses a center control
absorber to cross-link shocks on opposite corners of the vehicle,
substantially reducing pitch and yaw by offsetting opposing inputs.
With X-REAS the new 4Runner corners flatter, smoother, and handles
choppy pavement more easily.
Every Safety Precaution Considered
On-road vehicle dynamics are further enhanced by a suite of
high-performance, state-of-the-art safety systems. Standard on 4Runner
is Toyota's Star Safety System?, which includes Vehicle Stability
Control (VSC) with traction control (TRAC), an Anti-Lock Brake System
with Electronic Brake-force Distribution (EBD) and Brake Assist.
Vehicle Stability Control (VSC) helps to ensure stability by
compensating for oversteer or understeer. The system uses selective
braking and modulated engine output to keep the vehicle in line with
the driver's intended course. On 4x2 vehicles, the Auto LSD (Limited
Slip Differential) system allows for better traction on slippery
sections of roadway.
The four-wheel ABS with EBD provides the 4Runner anti-lock
stopping control with optimal brake proportioning, whether the vehicle
is loaded or unloaded. Hill-start Assist Control (HAC), standard on all
4x4 models and the 4x2 V6, suppresses backward roll when switching from
brake to accelerator. All 2010 4Runners have active headrests for
driver and passenger, three-point seat belts for all seats, an
energy-absorbing body structure and an energy-absorbing hood to help
protect pedestrians.
A system of eight standard airbags includes front, side-mounted
and knee airbags for the driver and front passenger, and side curtain
airbags for the second and third row.
Everyday Convenience and Utility
The all-new 4Runner has been thoughtfully equipped with features
and systems to create a comfortable travel space, allowing for
convenient operation in everyday use.
The larger interior has been completely redesigned with comfort
and utility in mind. The front seats have a greater range of
adjustment, both vertically and front to rear.
A bright, highly visible dash houses speedometer, tachometer,
voltage, fuel and temp gauges, plus a combination meter that offers
multiple functions. An Eco-Driving feedback system allows the driver to
manage fuel consumption in real time. Within easy reach of the driver
is an overhead console that organizes the off-road control switches
into one location. Features like a compass indicator and outside
temperature display add functionality in outdoor settings.
A manual climate control air conditioning system is standard on
SR5 and Trail grades. An automatic dual zone climate control air
conditioning system is standard on the Limited. The system features
driver and passenger independent temperature controls, providing
separate comfort levels.
Cargo-Carrying Versatility
The cargo area has been re-engineered to be more versatile than any SUV on the market.
More cargo space is available due to the fold-flat second-row rear
seats, which do not require removal of the headrest for rearrangement.
For models with three rows of seats, the third row seats are split
50/50, and they readily fold flat to allow the seatback to become the
floor of the luggage compartment. They can be folded from the side, or
at the rear, using separate one-touch mechanisms. With this new
arrangement, more cargo space is available without removing seats, and
longer items can be conveniently stored.
