Performance Worthy of the "Jeep" Name
Born in 1941 as a military vehicle for the U.S. Army, "Jeep" has a long history. Long before European brands' SUVs dominated the market as major players, Jeep identified market needs and was cherished as a special existence. A tough body and four-wheel-drive capability. Its appearance is the very image of today's SUV. This time, the OPENERS editorial team embarked on a long drive in the latest Jeep models, aiming for Hakuba Happo-One in Nagano Prefecture during mid-winter.

SUV = America: An Enduring Image
Considering the Japanese market, recently,BMW'sX SeriesandPorsche'sCayenne,Audi'sQ5, among others, European brands' SUVs have become major players dominating the market. However, the very concept of an SUV was originally an area of expertise for American brands. As you know, many people still instinctively say "A Jeep has arrived" when they see a rugged, so-called four-wheel-drive vehicle.
Even luxury models from top American brands like Cadillac and Lincoln offer SUVs in their lineups, and for American customers, SUVs are an indispensable presence. The fact that almost all automotive brands selling in America, including Japanese manufacturers, have SUVs in their lineups demonstrates how much SUVs are loved in the United States.
The brand that continues to lead this enduring American popularity for SUVs is the aforementioned "Jeep." Starting its history in 1941 as a military vehicle for the U.S. Army, Jeep is recognized today as the world's first four-wheel-drive brand, a synonym for "4WD," even if its post-World War II history is a separate matter.
The "Wrangler," which inherits the DNA of the "Willys," an icon symbolizing ruggedness and a tough image derived from its four-wheel-drive capability, is of course part of the lineup. In addition, with luxurious models represented by the "Grand Cherokee" and the sophisticated, urban-style "Compass", the modern "Jeep" is a manufacturer offering a full lineup of four-wheel-drive vehicles.
Many people might immediately think of the "Cherokee" when they hear "Jeep," but we will proceed with the story, and you will find out what has become of the "Cherokee" later.
The stage for this test drive was Hakuba Happo-One in Nagano Prefecture. First, we set off from Tokyo at the wheel of the "Compass." The route to Hakuba was primarily on expressways.

To Hakuba in the "Compass"
To clearly differentiate itself from its sister model, the "Patriot", which was previously sold as an entry-level model, the "Compass" initially offered only front-wheel-drive models in Japan. However, following the discontinuation of the Patriot, 4WD models have also been added. The engine is a 2.4-liter inline four-cylinder, producing a maximum output of 125 kW (170 PS). The current model uses a 6-speed automatic transmission instead of a CVT. By operating the shift lever left and right while in D-range, manual shifting is possible.
While it's a good size for driving in Japan, it's classified as a compact model in the United States. However, it's still American-sized. Even as a compact, the rear seating is more than adequate, and the cabin offers enough space and comfort for a long drive from Tokyo to Hakuba without any issues.
On the highway, we enjoyed a relaxed cruise. The 125 kW (170 PS) of power is more than sufficient for the 1.8-ton body. While not exactly fast, it has enough power to keep pace with highway traffic. The newly paired 6-speed automatic transmission allows for smooth gear changes and contributes to better fuel economy. The JC08 mode rating is 10.7 km/liter. On the highway section from Takaido, it felt like it was achieving better mileage than the stated figure.
After about three hours of driving, as the scenery turned to snow, we were able to test the true capabilities of the Patriot. The main roads to Hakuba were cleared and dry, but stepping onto a side road revealed patches of slushy snow on the asphalt. As we gained altitude, the weather gradually worsened, and it began to rain. The road surface became slippery, requiring caution. However, the Compass, equipped with studless tires, climbed the inclines steadily without any issues, as long as we avoided sudden maneuvers.
As can be inferred from its engine layout, the Compass is a full-time 4WD based on a front-wheel-drive system. However, it is a Jeep, after all, and it handles all weather conditions without the driver needing to be particularly aware of it. This potential to safely navigate any situation is crucial. On a special snow course isolated from public roads, the traction control system regulated power, suppressing tire slip when accelerating. It demonstrated the ability to overcome ruts with ease.
For this test, we drove with the Compass in full automatic mode, assuming normal usage, and its nimble full-time 4WD performance was more than satisfactory. Especially in situations common on public roads where one side is dry asphalt and the other is packed snow, creating uneven road conditions, the Compass appropriately controlled the drive force, allowing for stable driving without the car swaying left or right. This sense of security is paramount in everyday life. It would be a strong ally in snowy regions.

The Luxurious "Grand Cherokee"
Following its recent minor facelift, the "Grand Cherokee" now features a more aggressive front fascia. The lineup includes the "Laredo" with a 210 kW (286 PS) 3.6-liter V6 engine, the "Limited" with standard luxury equipment, and the "Summit" powered by the traditional 5.7-liter V8 engine. The Summit offers powerful acceleration thanks to its 259 kW (352 PS), and above that reigns the "SRT8" with a 6.4-liter V8 engine producing 344 kW (468 PS).
The SRT8 is a special model within the Grand Cherokee range, boasting performance that could be described as sports car-like. Jeep and Chrysler position the "SRT" series as their flagship. This is comparable to models like AMG for Mercedes, and in North America, the SRT designation alone often garners envious glances.
The Grand Cherokee is equipped with the Selec-Terrain system, which integrates 12 vehicle management systems, including the accelerator, transmission, transfer case, traction control, and stability control, allowing anyone to easily unleash its exceptional off-road capability. The rotary dial located below the shift lever offers five modes: Sand, Mud, Auto, Snow, and Rock. Normally, selecting "Auto" is sufficient, as the Grand Cherokee will automatically deliver optimal performance regardless of the weather conditions.
In Snow mode, power output is reduced to minimize slip and generate stable traction. When we tried Mud mode, it allowed for a controlled amount of slip, enabling drifts, where the vehicle slides sideways. Incidentally, Mud mode is used for navigating muddy terrain, while Rock mode is for slowly traversing rocky or rough ground.
Unlike the compact Compass, the Grand Cherokee's ride is characterized by a sense of heft. It delivers stable traction in any situation, sometimes quietly, sometimes powerfully propelling its large body forward.
The capability of the Selec-Terrain system is truly remarkable. With this one vehicle, it feels like you could drive anywhere in your daily life. It can start moving effortlessly even on ice-covered roads where it's difficult for people to walk.
The interior also maintains a luxurious impression, offering a first-class finish as a luxury car. Thanks to the heated seats, heated steering wheel, and the premium audio system from Harman Kardon, we were able to drive comfortably on the harsh, cold roads of Hakuba. It's easy to understand why many North American celebrities choose the Grand Cherokee.

The "Wrangler": A Direct Descendant of Jeep's Tradition
The "Wrangler" is the antithesis of the luxurious Grand Cherokee. The lineup includes the 2-door model, a direct descendant of the "Willys," and the 4-door model called the "Wrangler Unlimited." As its wild appearance, with easily removable doors and roof, suggests, it's safe to say there is no tougher civilian 4x4 available.
It employs the traditional robust ladder frame and features rigid suspension on both the front and rear. The engine is a 3.6-liter V6 producing 209 kW (284 PS), paired with a 5-speed automatic transmission. It utilizes the "Command-Trac," the only part-time 4WD system in the current Jeep lineup. Only the Wrangler series is equipped with a locking differential.
In extremely low-speed situations like rocky terrain, the 4x4 low range is selected, while for slippery surfaces such as snow-covered roads or sandy terrain, the 4x4 high range is chosen. The switch from low to high range can be made while driving, as long as the speed is below 88 km/h. In 4WD mode, the torque distribution between the front and rear is fixed at a 50:50 ratio.
Accustomed to monocoque bodies, this direct ride feel might seem a bit harsh, but it's not impractical for daily use. The view from the high seating position is unique, and it's easy to gauge the four corners of the vehicle. This driving position and body design are invaluable when navigating off-road. The ample ground clearance and high grip levels make it a top contender globally, alongside the Land Rover Defender.
Even if it's unfamiliar to us, it's said that professional adventurers choose the Wrangler when venturing into uncharted territories. It's reliable in situations where life is on the line. While it now includes modern comforts like air conditioning, power steering, and power windows, it fundamentally offers genuine off-road performance, embodying "The Jeep" itself.
Even when driven onto a special course on a rutted snowy surface, the Wrangler's off-road capability, which seemed unfazed by the adverse conditions, was truly exceptional. Even large ruts that would cause ordinary cars to get stuck could be cleared by carefully and steadily advancing.
With rough accelerator inputs, the traction control system intervenes effectively, preventing any loss of grip. The word "unwavering trust" is truly fitting for the Wrangler.

The New Cherokee Also Unveiled Early
The new Cherokee, which breaks away from the heavy-duty image brought by its previously square body, will be launched in Japan this spring. Deliveries began in North America last fall, and it has reportedly received excellent reviews. The new model adopts a front-wheel-drive platform with the code name "KL," and its more urban-styled interior and exterior design signify the arrival of a new era.
The North American model offers a 2.4-liter inline-4 engine and a 3.2-liter V6 engine, paired with a 9-speed automatic transmission. While details for the Japanese specifications have not yet been revealed, Jeep's official website has launched a teaser site, which includes images suggesting the presence of a Selec-Terrain system (system name in Japan not yet disclosed) inherited from the "Grand Cherokee."
We had the opportunity to closely examine the actual vehicle displayed at this test drive event. Its aggressive exterior design, reminiscent of a bird of prey, seems to represent a complete 180-degree shift from Jeep's previous image. Even with such a significant design change, it is certain that the traditional off-road capability befitting the "Jeep" name has been inherited. We eagerly await its official debut.
