Considering a mid-sized diesel 4×4 SUV as a reliable and robust vehicle? The Mercedes-Benz W164 (ML320 CDI) and the Jeep Grand Cherokee CRD (2007-2009 models) are often on the radar for those seeking a pre-urea diesel engine with a solid reputation. Both SUVs house the OM642 engine, a powerplant known for its longevity and widespread use. Let’s delve into a comparison to help you decide which suits your needs better.
The OM642 engine is indeed a strong contender for reliability. Having been utilized across various Mercedes-Benz platforms for years, it has generally garnered positive feedback. Owners often praise its durability and performance. However, like any engine, it’s not without potential drawbacks. Some reported issues include oil cooler leaks and swirl flap motor problems, which are worth investigating when considering a used model. Despite these potential issues, the OM642 remains a well-regarded diesel engine.
When it comes to 4×4 capabilities, both the Benz W164 ML320 CDI and Jeep Grand Cherokee CRD offer all-wheel drive. However, a key difference lies in the Jeep’s inclusion of a low-range gear selection, enhancing its off-road prowess in more demanding terrains. While the Mercedes-Benz W164 provides capable 4×4 performance for most situations, it lacks the low-range option found in the Jeep. If serious off-roading is a priority, the Jeep might hold an edge.
Moving to electronics and overall complexity, the Mercedes-Benz W164 is generally perceived as being more technologically advanced and feature-rich than the Jeep Grand Cherokee of the same era. This translates to a more luxurious and refined driving experience in the ML320 CDI. However, increased electronics can potentially lead to more complex repairs and potential electrical issues over time. The Jeep, while still electronically sophisticated compared to older models, might present a slightly less complex system to maintain. Owners considering DIY repairs should weigh this factor.
In terms of ride and amenities, the Mercedes-Benz W164 ML320 CDI is expected to offer a more comfortable and luxurious experience compared to the Jeep Grand Cherokee CRD. The Jeep, with its truck-like origins, might provide a stiffer ride and a more utilitarian interior. Conversely, this truck-like nature can be an advantage off-road, and the Jeep also benefits from a significant aftermarket support for off-road modifications. The W164, while capable off-road, leans more towards on-road comfort and luxury.
Ultimately, the choice between a Benz W164 ML320 CDI and a Jeep Grand Cherokee CRD depends on your priorities. If luxury, on-road comfort, and a sophisticated driving experience are paramount, the W164 is a strong contender. If off-road capability, a potentially simpler electronic system, and aftermarket support are higher on your list, the Jeep Grand Cherokee CRD might be more appealing. Both offer the benefits of the reliable OM642 diesel engine, making them solid choices in the mid-sized diesel 4×4 SUV category.
