Toyota 4Runner, 2010
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 Toyota 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 Toyota 4Runner continues to evolve while remaining close to its roots. The all-new fifth-generation Toyota 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 Toyota 4Runner smarter, more comfortable, and more versatile than ever.
Exterior Styling
The design strategy for the new Toyota 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 Toyota 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 Toyota 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.
The Trail grade is designed to maximize off-road performance with a superior approach and departure angles, high ground clearance, and an array of functional upgrades for the most demanding active outdoor enthusiast. It can be distinguished by a unique hood scoop, unique 17-inch wheels, black outer mirrors, front and rear bumper guards and dark smoke treatment on the head and tail lamps.
The Limited and SR5 grades add to the muscular design with special touches that provide a premium appearance. The front end includes a chrome-plated front grille insert, fog lamp bezel and front bumper molding. Front and rear overfenders and side skirts are color-keyed. Chrome plating is also found on the side molding, roof rack and rear bumper.
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 Toyota 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 Toyota 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 Toyota 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.
On-Road Driving Dynamics
The new Toyota 4Runner may be a truck-based SUV, but it offers the kind of drivability and riding comfort more often associated with car-based platforms.
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 Toyota 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.
The 2010 4Runner now offers the new Safety Connect™ telematics system. Available by subscription, with or without the optional navigation system, Safety Connect offers four safety and security features: Automatic Collision Notification, Stolen Vehicle Location, Emergency Assistance Button (SOS), and Roadside Assistance.
Safety Connect is standard, factory-installed hardware on the Toyota 4Runner Limited and available via an active subscription. An included one year trial subscription will be offered on equipped new vehicle purchases.
A rear-view monitor system is standard on Limited and Trail grades and optional on the SR5. The system displays in the rear-view mirror, helping to keep track of hard-to-see objects to the rear of the vehicle. A rear clearance sonar system is standard on SR5 models.
