Is a four wheel drive vehicle required for Death Valley backcountry trips?
It is most definitely recommended! Even though most of the dirt roads will be traversable in two wheel drive, there are portions that are made easier with 4wd traction, and still other areas that will absolutely require all four wheels transmitting power to the ground in order to avoid damage to the terrain and the vehicle. The most demanding portions are not navigable with 2wd at all, requiring a 4×4 equipped with a low-range gearing option. Even the easiest roads may occasionally have a washout from a storm that would be made easier with four wheel drive traction and low range gearing. Most standard four wheel drive BEVs will be able to negotiate the majority of dirt backroads in the Park, often in two wheel drive.
