The 2022 Mercedes-Benz E450 4MATIC All-Terrain is in a very small and upscale niche: the swanky wagon. It’s got the practicality of an SUV with the luxury and handling of the E-Class sedan.
Base Price: $68,400
As Tested: $83,270
Mileage: 21 mpg city/28 mpg highway/24 mpg combined
The E450 All-Terrain gets a couple of tweaks for 2022: automatic high-beam headlights become standard, and Nautical Blue Metallic is added as an exterior color. The wagon was first introduced for the 2010 model year and was last redesigned for 2017.
It comes in just one trim starting at $68,400. All-wheel drive is standard. Numerous packages and options are available that quickly send the price higher. There’s room for seven passengers thanks to a rear-facing third row.
Its rivals are the Audi A6 Allroad and the Volvo V90 Cross Country. Of course, the Subaru Outback is also a wagon but it’s not considered a luxury vehicle.
The E450 All-Terrain is powered by a turbocharged 3.0-liter inline-six and a mild 48-volt hybrid system with a nine-speed automatic transmission. Total output is 362 horsepower and 369 pound-feet of torque.
The E450 All-Terrain handles a lot like the E-Class sedan. The powerplant is always willing and responsive. Acceleration is snappy from a stop—Mercedes-Benz says it can go from zero to 60 mph in 5.3 seconds—and there’s plenty of smooth power when speeding up for merging and passing. This wagon excels as a cruiser, eating up the miles on a family road trip. Engine, wind and road noise are barely noticeable. You can adjust the air suspension to get a little more ground clearance if your adventures include some light off-roading.
Fuel economy is decent for the class. EPA ratings are 21 mpg city and 28 mpg highway with a combined rating of 24. I got 23 mpg during my week with a mix of city and highway driving. Premium gas is required.
The posh cabin is beautiful with top-notch materials and exemplary fit and finish. There’s plenty of room for passengers and cargo. The latest technology abounds including a huge 12.3-inch touchscreen with the latest MBUX interface that dominates the center stack. The front seats are extremely supportive and comfortable. My tester has the optional massaging seats to pamper the driver and front passenger. The folding, rear-facing third row seats give you the option of hauling more passengers when needed.

The MBUX infotainment system is overwhelming at first with a huge array of menus and will take time to figure out. Once you’re up to speed, the system works well and responds quickly to commands via the touchscreen, touchpad, steering-wheel controls, voice, and gestures.
The E450 All-Terrain has 35 cubic feet of space behind the rear bench, and 64 cubes with it folded. The cabin has numerous bins and cubbies for stashing smaller items. The split-folding 40/20/40 second row makes it easy to haul passengers and cargo. A power liftgate is standard.
