Perennial "wild" "off-road old cannon" put
Non-bearing body, time-sharing four-wheel drive, nitrogen suspension,
Put a few locks and the like on your mouth,
But for a broader audience of hardcore off-road culture,
The brand pedigree of the off-road vehicle is also important.
In terms of life, the Wrangler deserves it,
It has long been a classic within a classic
The classics accumulated over the past 80 years have lasted for a long time. Even in the context of today's era of fierce collision between new energy and traditional power, the appearance of the fourth generation (JL) Wrangler 4xe in the off-road kingdom has sparked electric sparks, and for many years it has been sympathetic to land Rover Defenders on the sidelines.
The core of the evolution of the Wrangler 4xe is undoubtedly the "heart" under the cover, on the basis of the fourth generation of Wrangler gasoline engine, the 4xe version respectively increased P1, P2 motor, of which P1 motor for vehicle power supply system, engine start, maintenance of compressors, water pumps, etc. Normal work, and the vehicle start-up stage to give additional power to make up, so compared to other brands BSG light mix system, 4xe strength is that the P1 motor power is very high, the maximum power is 33 kilowatts, the maximum output torque is 53 NG meters.
The P2 motor is positioned in the gearbox, connected to the fuel powertrain through a binary clutch to achieve a true hybrid mode, while in order to cope with the harsh off-road conditions, the P2 motor has a maximum power of 100 kW and a maximum output torque of 250 Nm, which is close to the mainstream 1.5T engine performance. For this reason, such a motor makes the Wrangler 4xe can only choose the second generation ZF 8AT based, because the third or fourth generation ZF 8AT due to the shorter length, the P2 motor volume has a strict limit, so the 4xe can only choose the 2nd generation ZF 8AT, and integrate a multi-disc clutch at the end of the transmission in the form of a transfer case.
With the help of a 2.0T turbocharged engine and two electric motors, the 4xe version finally achieved a maximum power of 276 kW and a maximum torque of 637 Nm, and in order to match the extra output of the motor, the Wrangler 4xe Sahara version of dana front and rear axle models were upgraded from the fuel version of the M186/200 to the same M210/220 as the Robin Hood version. In addition, the speed ratio changes from 3.45 to 3.73, resulting in a stronger low-speed torque amplification.
Under the road performance, ZF 8AT has a gear ratio of up to 4.7, combined with the power output of 250 Nm brought by the motor P2 motor, which makes the starting posture idle and the overall acceleration ability is fierce. Compared to the gasoline version, the driver even has the illusion of driving a performance motorhome. Until the middle section accelerates, the engine officially intervenes, the 4xe returns to the true color of the gasoline engine, the 8AT gearbox exceeds the broad transmission ratio range of 7.03, which greatly improves the performance of the Wrangler NVH At the same time, the mid-section re-acceleration force is thicker than the previous generation of V6 power, so after entering the plateau, the turbocharged engine plus the motor fit, the 4xe highway performance comprehensively surpasses the previous generation of self-priming V6 is an inevitable result.
Whether it is a 4xe rupees or a Sahara model, the fuel tank volume is not much smaller than the gasoline version, and the 65L total volume makes the road endurance more robust than the gasoline version, but the difficult low-speed off-road process, the ternary lithium battery pack with a total capacity of 17 kWh, will not support the pure electric power output for too long. In this kind of car use scenario, the driver needs to turn on the E-SAVE mode to maintain the battery power, otherwise when the power is exhausted, there is no long-distance energy recovery, and the motor will not be able to give overall power support.
In highway mode, there is no need to worry about the battery level is at a low level, through the forced energy recovery button located in the center console, encountering downhill road conditions, the drag feeling of the whole vehicle brought by strong recovery can bring a comfortable braking experience, that is, reduce the burden of the long-distance downhill braking system, the charging process is also quite efficient, and the charge has been fully prepared for the next driving.
Wrangler evolved to the fourth generation, the power system electrification progress has been obvious, the new 8.4-inch Uconnect in-vehicle information system in the car is also of great benefit to driving help, in addition to car navigation, mobile phone mapping, interconnection and other entertainment functions, the system can timely monitor the operation of key components, such as transmission oil temperature, transfer case oil temperature, four-wheel drive status and vehicle inclination status, etc., can be obtained in the system details, while the 4xe model to increase the hybrid page, Monitors battery charge and discharge status.
Based on the newly developed vehicle electrical architecture system, the Wrangler 4xe series is equipped with adaptive cruise, full-speed collision warning, parksense, Parkview and many other active and passive practical equipment, it can be said that this generation of Wranglers is completely goodbye to the steel straight man style.
In the context of increasingly stringent emission regulations, the development of hard-core SUVs is destined to be not optimistic. However, under the spur of the policy, the Wrangler has clearly defined the direction, outputting stronger performance with smaller displacement, and laying a strong foundation for the transformation of Jeep's hard-core off-road culture.
