The All-Terrain gets the same interior as the recently revamped E-Class. As far as interior upgrades go, this one is pretty substantial. The restyle comes with new interior color options, an all-new steering wheel, and dual 12.3-inch displays. One display is mounted directly behind the steering wheel and serves as a digital instrument cluster. The second is neatly housed above a lovely curved piece of interior trim housing four air vents. This particular unit is a touchscreen interface and runs Mercedes's latest MBUX software - perhaps the E-Class's biggest upgrade.
Mercedes also removed some of the clutter found on the pre-facelift model. The only physical buttons are there to operate the climate control, which is a smart move. The touchpad is smaller than it was before and didn't protrude as much. For the first time, it looks as if it were part of the overall interior design rather than an afterthought.
The E 450's interior is classic Mercedes. The satin-finished wood and round air vents look amazing - as opposed to the brushed metal look and square vents on the E 63 sedan we recently drove which looked like an industrial vent factory. What's less convincing is the steering wheel. It's all-new for the facelift, and the tri-spoke design itself looks and feels great, but the piano black is a little cheap and will be a magnet for fingerprints.
As for the rest of the cabin and the seating, Mercedes has pulled off quite the trick in the fact that the E450 All-Terrain is a seven-seater, technically. That's courtesy of a pair of rear-facing jump seats in the trunk that will seldom see use but are a nifty throwback to an era when wagons were popular family runabouts.
In the front of the cabin, the double sunroof is nice and the seats themselves are very comfortable - particularly the multicontour seats equipped to our tester with massage functionality. Front occupants get 37.5 inches of headroom, 41.7 inches of legroom, and 57.8 inches of shoulder room, which is a little tighter than the Volvo V90, but not by much. In the back, the E450 has 38.2 inches of headroom and 36.1 inches of legroom, which is more than enough for most, and there's enough shoulder room to fit three abreast on shorter journeys without complaints.
Those jumpseats we mentioned flip up from the floor when needed and have their own seatbelts. They're small, so only suitable for small children, but they'd have fun back there, especially as they get to look out the rear windscreen.

The E-Class is a sweet spot for Mercedes where a higher price tag justified the ability to offer a multitude of upholstery finishes - 13 of them, in fact. There are five no-cost options - various color combinations of Mercedes' MB-Tex leatherette upholstery including Black, Black/Nut Brown, Black/Macchiato Beige, Neva Grey/Magma Grey, and Magma Grey/Macchiato Beige. Genuine leather costs an additional $1,620 and is available in the same combinations, except for Macchiato Beige/Magma Grey. Nappa leather upholstery retails for $2,990 and is available in Black, Black/Nut Brown, and Macchiato Beige/Magma Grey. For those who want the most luxurious option available, there is only one designo option available. Tack on the $4,900 designo Exclusive Nappa Leather Package and you get Macchiato Beige/Saddle Brown Exclusive Nappa leather, a topstitched Nappa leather dash, a Macchiato Beige headliner in faux suede, and designo floor mats.
As for trim inserts, there are six options. Only the designo Black Piano Lacquer adds anything to the price of the Mercedes-Benz E-Class All-Terrain as a $1,300 option. We'd stay away from it anyway because it highlights smudges so easily. Instead, the no-cost options of Natural Grain Black Ash wood, Brown Ash wood, Natural Grain Brown Ash wood, Burl Walnut, and Natural Grain Grey Ash Wood are much better suited to the atmosphere of the car.
The E-Class All-Terrain offers a class-leading 35 cubic feet of cargo capacity. It easily trumps the Volvo V90's 25.5 cube trunk and the 30 cubes provided by the Audi A6 allroad. The rear seats fold forward and nearly flat, in which case the Mercedes has 64 cubic feet of space for stuff. The only thing the E 450 can't do is tall cargo, which is where it falls short compared to the GLE-Class. That said, the cargo bay is far more practical than a GLE-Class Coupe, and with a lower load-in height, you're less likely to scuff the rear bumper.
Inside the cabin, the door pockets are on the narrow side, but the glovebox is significant, as is the storage space underneath the armrest. Ahead of the infotainment touchpad, a flip-up lid reveals two cupholders and space for a phone or set of house keys, while in the rear, the center seatback folds forward revealing two more cupholders.

The E-Class All-Terrain Wagon boasts the same standard features as the revamped sedan. It boasts all-LED exterior lighting, a power tilt-and-slide glass sunroof, power-adjustable front seats with a memory function, dual-zone climate control, heated front seats, a fold-out rear-facing third-row, keyless go, power liftgate, an illuminated entry system, and 64-color interior ambient lighting. As with all Merc products, the options list is extensive, with items like tri-zone climate control, massaging front seats, seat ventilation, heated armrests, a head-up display, and even soft-close doors. The standard raft of assistance features includes attention assist, blind-spot assist, a rearview camera, rain-sensing wipers, advanced tire pressure monitoring, and Pre-Safe. Most of the advanced driver assists are only available as part of an optional package that gives you semi-autonomous capability and nearly every conceivable assist.
Like the rest of the new Mercedes lineup, the E450 gets two 12.3-inch screens next to each other, one for the driver cluster and one for the infotainment features. You can touch the infotainment screen, control it with the touchpad (though this doesn't have a wrist rest to brace your hand, so it's harder to use it while driving), use the steering wheel touchpad, or yell "Hey, Mercedes," followed by instructions and/or questions.
Other functionality includes the regular AM/FM radio, HD Radio, Bluetooth, and twin USB-C ports, while Apple CarPlay and Android Auto are also included. You have to pay extra for SiriusXM, though. Navigation is standard, but from the options list, augmented video for this is available, which uses the front-facing camera and overlays directional arrows and street names onto the screen so you never miss a turn. The standard audio is nothing to write home about, but a 590-watt, 13-speaker Burmester system can be equipped. In-car Wi-Fi is also available, as is wireless device charging.
As far as actual interaction with the system goes, the screen works quickly and doesn't get hung up. The voice control system in this particular vehicle never seemed to recognize my voice prompts, but we have had better success with it in other models. We're hoping this was a one-time thing.
