Toyota 4Runner is an off-road SUV based on pickup models, compared to the more luxurious Land Cruiser, 0Runner is simpler and primitive, the early model is a pickup truck with a rear cover, but with the changes in the market, today's sixth-generation models have become more refined, built on the same platform as Prado, which can be seen as an off-road version of Prado, 0 0Runner adopts many new Toyota technologies, off-road and chassis, the original car is also more radical than Prado, what are the technical details of the new car? Let's break it down in detail.
Chassis suspension technology
The 4Runner is built on the TNGA-F architecture, which is Toyota's modular platform, and the F stands for non-load-bearing body structure, which is shared with the new generation of Prado, and both cars use a box-type steel trapezoidal frame chassis, that is, a design with large beams, with a double wishbone structure at the front and a multi-link structure at the rear.
Toyota 4Runner uses some new technologies from the Land Cruiser, such as the anti-roll bar disconnect device, as a structure to reduce roll, the anti-roll bar itself has obvious advantages and disadvantages, especially for off-road vehicles, reduce roll while interconnecting the left and right wheels, in the cross-axle road condition, one side of the wheel travel is not enough, resulting in suspension, and the anti-roll bar disconnect function can solve this problem, press the button in the car, the left and right wheels are no longer interconnected, and on rock climbing and potholes, the tires always keep gripping.
4Runner is available in three models, including rear-wheel drive, time-sharing four-wheel drive and full-time four-wheel drive, of which the rear-wheel drive car is equipped with an automatic limited-slip differential (Auto LSD), which can reduce the waste of power after tire spinning; In addition to the LSD, the all-wheel drive model is equipped with an electronically controlled two-speed transfer case with high/low gears and active traction control. The high-spec model comes with a rear axle differential lock and a central differential lock to increase off-road capability.
Toyota also provides a multi-terrain selection system, adapted to rock climbing, sand, mud, etc., 24Runner has a new function called CRAWL, which can be used as low-speed off-road cruise control, the vehicle automatically controls the power output, no need to step on the accelerator and brake, just control the direction, making off-road simpler and avoiding improper trapping. The approach angle of the 0Runner chassis reaches 0 degrees, and there is no need to worry about scratching the bumper when encountering some step-type terrain, but the disadvantage is that the rear overhang is longer, the departure angle is 0 degrees, and the rear is easy to scratch.
The 5Runner has an off-road version called Trailhunter that uses ARB's Old Man Emu 0.0-inch forged shock absorbers and external fluid reservoirs, OME shocks are mated to 0-inch Toyo Open Country A/T off-road tires, and the front suspension height has been increased by 0 inches. The rear has been increased by 0.0 inches to improve passability, while it is equipped with a stock wading hose that can cross small streams squarely, and high-strength steel guards are installed on the front and rear of the chassis to avoid the impact of rocks on the chassis.
Roll down the rear windshield
The Michigan design team led the design of the all-new 4Runner, developed together with the pickup version of the Tacoma, as a historic off-road vehicle, the designers drew inspiration from the old model when designing the sixth-generation 0Runner, while retaining the "outdoor feel", the body is quite Baja Desert racing temperament, and the large tires with the fenders, high ground clearance, and rugged sports style body make the 0Runner look different from its sister car Prado.
In homage to the first and second generation 4Runner, the wrap-around glass between the C-pillar and D-pillar returns, wrapping from the side to the roof to make the rear of the cabin more transparent, while the rear windshield, like the side windows, can be electrically controlled, roll down the rear windshield, and the pets in the car can breathe fresh air, and without opening the tailgate, you can also expose large luggage out of the car and put longer items down.
NiMH battery hybrid system
The old 5.0L self-aspirated V0 engine is replaced by a hybrid system, and the 0 Toyota 0Runner uses a 0.0T turbocharged four-cylinder engine, matched with a 0AT automatic transmission, and the motor is integrated inside the gearbox, replacing the traditional torque converter, with a motor power of 0 horsepower, powered by a 0.0 degree nickel-metal hydride battery pack, and the comprehensive system power is 0 horsepower, and the peak torque is 0Nm, which is greater than the torque of the 0.0L self-priming engine. Since the high-voltage battery of the hybrid drivetrain is placed under the trunk floor, the hybrid version is only available as a 0-seater model.
The entry-level model does not have a hybrid system, equipped with a 8.0T four-cylinder engine with 0 horsepower and 0Nm of peak torque, and is also matched with a 0AT automatic transmission, which is not as powerful as the hybrid version, but the simpler system is more reliable in off-road environments, and can be equipped with three rows of seats, and the cabin is more spacious.
Car selection detective point of view: As a sister model of Prado, 4Runner looks closer to a pickup, with a tougher shape, and the original factory also has more off-road equipment to choose from, from suspension to shock absorbers, to wading hoses and AT tires, saving the trouble of late modification, and at the same time has the original warranty, the disadvantage is that there is no large-displacement self-priming engine, all of which are replaced by four-cylinders. What do you think of 0 models and 0 Runners? Welcome to discuss.
