Lexus Gx550 vs Mercedes-Benz E220

What's the difference?

The new Lexus GX 550 Sports Luxury looks fantastic and has enough mod cons to satisfy a family but it’s not as luxurious as you’d expect from a premium brand and the fuel economy and driving range will turn off some. But if you’re still interested, there’s a lot here that will make you happy and it’s one of the smoothest 4WDs I’ve driven.

Given Mercedes-Benz's rich heritage with station wagons, it is a bit of a shame Australia’s preference for SUVs has reduced the line-up to just one variant this time around.

I'm glad they've picked the All-Terrain to fly the flag though, and Merc wagon loyalists should appreciate the extra versatility of its dirt road ability - if they're not mourning the loss of the extra two seats in the rear. Like the rest of the current E-Class range, the E 220 d All-Terrain is an excellent product overall.

The new GX 550 looks massive and while it shares the same platform as the Toyota LandCruiser 300 series, it doesn't share all of its bulk. They both stand at 1980mm wide but differ on length (5015mm vs 4980mm) and height (1670mm vs 1950mm), respectively.

The new design is fabulously rugged but each body panel looks meticulously crafted and is just the right size. This just means the proportions look right and your eye sort of glides over the big body rather than stopping on any one feature.

But having said that, there are a lot of nice features to focus on, like the long LED headlights and rear strip light, auto-folding side steps, 22-inch alloy wheels and sharply styled rectangular side mirrors.

The tailgate window can also be opened if you need to pop something into the boot but don't want, or have the space, to open the tailgate itself.

The styling takes a minor nose dive once you hit the cabin, though, because it doesn't look as sumptuous as you'd expect in a premium SUV.

I love the utilitarian and military vibe of the vertical dashboard, chunky air vents and relatively small windscreen. It looks great but some trims are plasticky and the touchpoints, while soft, are not Lexus-plush.

However, the technology looks gorgeous with an integrated 14-inch multimedia display and a 12.3-inch digital instrument cluster. The fixed sunroof with its two settings (clear or opaque) is also a lovely feature.

But on a whole, the GX 550's European rivals outclass it with their flashier cabins.

The All-Terrain styling pack is comprised of tough-looking front and rear bumpers, with unpainted plastic side skirts and wheelarch flares on all corners. This will all be welcomed by anyone who travels regularly on dirt roads, but the All-Terrain bits will also provide a handy disguise from urban parking scrapes.

The double-blade grille, wheels and roof rails are also bespoke to the All-Terrain, and the net result is a distinct personality that should satisfy the majority of previous E-Class Estate buyers previously opting for the AMG styling pack.

Interior trim is based on the regular E-Class Avantgarde package, but with specific rubber studded pedals and All-Terrain branded floor mats to align with the exterior treatment.

In the default suspension setting, the All-Terrain sits 29mm higher than a regular E-Class. Taller tyres make up 14mm of this, while the remaining 15mm is thanks to an elevated 'Air Body Control' air suspension. A further 20mm of lift is available with the All-Terrain drive mode selected, but only at speeds up to 35km/h.
 
The All-Terrain’s 20-inch alloys are a staggered fitment with 245/40 tyres up front and 275/35 at the rear, while taller-sidewalled 245/45R19 at each corner are a no-cost option, and essential if you wish to use snow chains.

Like the Estate available internationally, the All-Terrain rides on the same 2939mm wheelbase as the E-Class sedan but gains an extra 24mm in rear overhang to measure 4947mm overall.

The wagon body, extra kit and all-wheel drivetrain also add an extra 240kg to the kerb weight over the E 220 d sedan, with the All-Terrain tipping the scales at 1920kg.

The cabin of the new GX 550 is fairly practical with plenty of head- and legroom in each row (yep, even the third!). When you first hop in, it can feel a big snug on elbow-room but this feeling quickly dissipates.

Despite a 215mm ground clearance, access is pretty good for the front and middle rows due to the wide door apertures and side-steps. Third row access is a bit awkward for an adult but my eight-year old loved scampering back there this week.

The electric front seats are comfortable with their extra functions and I like the way the massage feature extends to the seat cushion as it limits fatigue on longer journeys. However, you sit on top of them rather sink into them which makes it feel a little trucky at times.

The wide middle row has a bench seat that will be comfortable for kids but an adult might get a sore behind on a long trip. The transmission tunnel also compromises foot room for adults but the seat is wide enough to make use of all three top-tether anchor points (there are ISOFIX mounts too).

It was a little bit of an effort to lift my big booster seat into the back because the GX 550 sits so tall but otherwise, there's plenty of room around a child seat for them not to feel like a sardine.

Individual storage is made up of a glove box that fits an owner's manual, a small shelf in the dashboard and a middle console that doubles as a cool box (mini fridge) and can fit up to four cans or bottles in it.

Each row gets four drinkholders and two USB-C ports but the front also enjoys a 12-volt socket and wireless charging pad. There's a 220V domestic plug port in the boot for larger appliances, too.

It's sometimes awkward to use the wireless charging pad because it's easy for your phone to slide around on it and it quite often disengaged from charging.

My son enjoyed all of the other amenities in the middle row, like the reading lights, climate control, two USB-C ports and retractable sunblinds and I applaud carmakers when they position rear directional air vents in the pillars and/or roof. It just makes it so much easier to cool down sweaty kids!

The 14-inch multimedia display has clear graphics and a responsive touchscreen. The layout is easy enough to get used to after spending some time with it and the sat nav is simple to use.

I like that the sat nav directions can be pulled into the 12.3-inch digital instrument cluster and head-up display.

There is a Lexus connected services app, which you get a three-year subscription to. It's easy to connect to the wireless Apple CarPlay and there is also wireless Android Auto.

The system also has Bluetooth and digital radio, which is a delight to use through the 21-speaker Mark Levinson sound system.

The cabin is rounded out by the well-shaped boot which has a massive 1063L of capacity when the third-row is folded. That's been more than enough for my family's needs this week and my German Shepherd was pretty comfy back there, too. The powered tailgate has a kick-function and there is a full-size spare wheel underneath the car.

Aside from the All-Terrain’s rugged looks, the greatest departure from E-Class Estate tradition is the omission of the third row of seats, which makes this one a strict five-seater.

One could argue that the Estate’s traditional rearward-facing third row is a bit old school next to the forward-facing setup used by seven-seat SUVs like the GLS, but it's a shame given the third row is still available in other markets.

The All-Terrain does offer a vast cargo area however, with an extra 130 litres (VDA) over the sedan with the seats up to total 670 litres (VDA). Seats down, this extends to 1820 litres (VDA), but it’s worth noting that both wagon figures are marginally smaller than the previous Estate’s 695/1950 measurements.

Facilitating full use of this space is the classic Merc Estate retractable cargo net, and a 670kg payload promises good scope for loading beyond a full passenger count. The air suspension will also automatically maintain a level ride height regardless of load.

As with all current E-Classes, there are bottle holders in each door plus two cupholders front and back and ISOFIX child seat mounts in the outward rear positions.

As per the non-AMG Mercedes passenger car norm, run flat tyres take the place of a spare tyre, but a space saver can be optioned to sit above the boot floor.

The All-Terrain theme follows the same path taken by key rivals Audi and Volvo with the A6 Allroad ($112,855) and V90 Cross Country ($99,900), which leaves BMW’s upcoming 5 Series Touring as the sole option in this segment not to adopt the semi-SUV look.

The $109,900 Mercedes is priced right between the Audi and Volvo, but note that the Audi brings a more powerful V6 to justify its slight premium.

The All-Terrain is available with a V6 internationally, but the 220 d four-cylinder diesel was selected for Australia as it's the closest match for the E 250 d that proved the most popular variant last time around.

Compared with a similarly specified E 220 d sedan (which kicks off at $92,900), Mercedes reckons they're about the same on price, but the All-Terrain throws in the wagon body and all-wheel drive pretty much for free. The All-Terrain also offers a significant value improvement over the previous E 250 d Estate which bowed out at $107,900.

Key inclusions for the All-Terrain over the already opulent E-Class are genuine leather trim, proximity unlocking, widescreen dash instrument that spans two thirds of the cabin, LED 'Multibeam' headlights, underbody protection and 20-inch twinned five-spoke alloys.

All GX 550 grades share the same 3.5L V6 twin turbo-petrol engine which produces up to 260kW of power and 650Nm of torque.

This 4WD has high- and low-gearing, as well as a bunch of driving modes to suit most occasions, like 'Eco', 'Comfort', 'Sport' and 'Sport+'.

The 10-speed automatic transmission shifts through its gears smoothly and it always feels like it's engaged in the right gear. Which isn't always the case for a big SUV!

The Sports Luxury is fitted with a towing hitch and cover but unlike the base Sports grade which has a 3.5-tonne braked towing capacity, this model only has a 3130kg capacity which might not appeal to families with big toys to tow. 

The All-Terrain’s excellent 2.0-litre turbo-diesel engine and nine-speed torque converter auto are carried across from the E 220 d sedan, which produces a decent 143kW/400Nm. Max torque is available from 1600-2800rpm.

The All-Terrain is the only Australian E-Class to pair this engine with the '4Matic' all-wheel drivetrain though, which uses a slightly rear-biased (45/55) torque split in this application.

I didn’t have high hopes for fuel economy because the official combined (urban/extra-urban cycle figure is a hefty 12.3L/100km but after mostly open-road driving, with some urban stuff mixed in, my real-world average came in at 11.8L.100km! This figure is based on my actual km travelled (358km) and litres of fuel used (42.41L).

While I’m surprised by the fuel usage result, I wouldn’t say this car has good fuel economy compared to its diesel-powered counterparts but it’s not terrible!

The GX 550 has a relatively small fuel tank compared to its Toyota cousins at 80L and based on the combined fuel cycle, you’ll get a theoretical driving range of up to 650km.

Not all that great. Not for a big family mover and not if you’re typically driving in the city, where fuel usage will be a lot higher.

The GX 550 only accepts premium unleaded petrol (95 RON), too.

The All-Terrain’s extra 240kg and no doubt less slippery body add 1.6L/100km to the E 220 d sedan official combined fuel consumption figure, but the wagon’s 5.7L/100km claim is still very impressive for a taller body nudging two tonnes. 

At this rate, the E-Class All-Terrain has a theoretical range of 1157km from its 66-litre fuel tank.

Oh my goodness the Sports Luxury is a masterclass on 4WD refinement! You never feel the bulk or weight of this massive SUV when you’re driving it. The power delivery is effortless and there’s lots of grunt available when you hit hills.

The handling is also very good with responsive steering and enough road feedback as a driver to make you feel comfortable with what the car is doing. There is some roll in corners but it can tackle more corners at speed than I thought it would. 

The high driving position makes me feel like I can see a long way ahead yet while visibility is mostly good, it can be compromised when you have the side window shades and the third row headrests up. Which is why I love the digital rear view mirror.

Overall, ride comfort is good with forgiving suspension and low cabin noise, even at higher speeds. It’s pretty easy to chat with all rows and there’s not a lot of engine noise which adds to the refinement. I do like hearing a V6 rumble but that’s just a personal preference. 

I was a little worried about hitting my local Westfield car park but this is a nimble SUV to manoeuvre and parking it is a breeze with the 360-degree camera system and parking sensors. 

Climbing aboard the All-Terrain, there’s a sense you're seated higher than its 29mm static ride height lift suggests. It's probably mostly psychological, and borne from the All-Terrain styling treatment, but something SUV fans will probably appreciate.

Otherwise it's mainly W213-generation E-Class from the driver's seat, which is a very good thing.

However, the extra 240kg of Estate body and All-Terrain spec over a regular E 220 d sedan is just enough to put a dent in the 2.0-litre diesel's performance. Mercedes claims an 8.0sec 0-100km/h figure, which is still more than enough to keep up with traffic, but just not as spritely as the sedan’s 7.3sec figure.

The combination of airbag suspension and the All-Terrain’s slightly taller tyre sidewalls help the wagon ride commendably well. There's no disguising the large-diameter 20-inch wheels over sharp potholes, but the experience is generally even better than we recall from any other existing E-Class.

The steering also feels slightly heavier, as though the level of assistance has been tuned for a touch more weight to add to the All-Terrain’s semi-SUV aura. If our perception is correct, it only adds to the sense of substance from the driver’s seat.

Its overall composure is maintained on dirt too, with the All-Terrain’s Victorian launch route offering a good dose of gravel and muddy unsealed roads. The all-wheel drive system keeps you pointing where you want and enables clean acceleration from the greasiest of corners. All of this highlights the All-Terrain’s potential as a ski field chaser.

We also detoured via some moderate fire trails, which gave us the chance to try the All-Terrain driving mode that lifts the suspension an extra 20mm and slackens the stability control and ABS to better suit low grip scenarios.

At speeds above 35km/h it reverts to Comfort mode, but will return to All-Terrain settings if you slow down again. In Sport mode or above 125km/h, the suspension lowers 15mm below normal to reduce aerodynamic drag. Even at full height it won’t challenge a GLE for clearance, but it’s significantly more capable than regular E-Class models.

Like all versions of the current E-Class, the All-Terrain carries the maximum five star ANCAP and EuroNCAP safety ratings. A brilliantly integrated suite of active and passive safety features represents the forefront of occupant and pedestrian protection, which goes well beyond its AEB, nine-airbag count, 360-degree parking cameras, rear cross-traffic alerts, and a pedestrian-protecting active bonnet.

These systems work in harmony to enable semi-autonomous driving, which is perhaps the greatest technical advancement of cars since we stopped riding horses.

Lexus offers the GX 550 with a five-year/unlimited km warranty, which is fairly standard compared to its Euro rivals.

You get five years capped-priced servicing which costs $5950 but the servicing schedule is a bit of a bear at every six months or 10,000km, whichever occurs first.

The E220 d All-Terrain is covered by Mercedes’ three-year, unlimited kilometre warranty, with service intervals pegged at either 12 months or a generous 25,000km.

Mercedes is yet to confirm capped service pricing for Australia, but we don’t expect the All-Terrain to stray too far from the $556, $1112 and $1112 figures applied to the E220 d sedan’s first three services.
