Mercedes-Benz E-Class vs Lexus LX570

What's the difference?

The Mercedes-AMG E53 Hybrid 4Matic+ is a superb blend of high-tech hybrid muscle and cossetting top-end luxury. Value is competitive, it looks (and feels) the business, despite the conventional sedan configuration it’s surprisingly practical (except for the modest boot), fuel-efficiency is a key benefit and safety is stellar. The ownership proposition is okay for the category but that’s not top of mind when an enticing series of corners ranges into view. It’s an impressive package.

The Lexus is awkwardly big and not very fleet of foot when you're negotiating the commute to work, school or the shops. It slurps fuel at a rate we're not used to seeing these days and it's not the easiest to park, even with all of its cameras and beepers.

The LX is far more at home out on the highway, where it is incredibly comfortable and quiet. One imagines the diesel entry-level model would do it all, but with less consumption. If you must have a V8, the LX 570 without the S might be even more comfortable without the sports dampers.

Either way, it's a lot of car for the suburbs.

At first glance the E53 passes as a flash-looking Mercedes-Benz E-Class running 20-inch rims, especially in the launch car’s rich ‘Patagonia Red’ finish.

But then, there’s something about the AMG sedan’s stance that sets it apart. Which makes sense because the front fenders are wider by 11mm on both sides (compared to the E-Class) to make room for a wider front track (increased by just over 30mm over the previous-generation E53).

Wheelbase has also increased by just over 20mm to almost 3.0m and the car’s more aggressive nose treatment enhances the distinctive look.

There’s the AMG-specific radiator trim with ‘Panamericana’-style vertical slats, the sleek dual-section headlights and a large lower inlet that directs air to an additional front intercooler as well as an external opening for a wheel-arch cooler.

In profile there’s barely a hard edge to be seen, although character lines in the bonnet and along the car’s flanks contribute to a taut surface treatment.

At the rear, horizontally-connected LED tail-lights feature a stylised Mercedes three-pointed star signature, then a rear apron housing a diffuser and twin double tailpipe ‘trims’ and a bootlid spoiler on the left and right round off a beautifully proportioned design.

Climbing inside means a trip to screen city with an upright digital display in front of the driver flanked by a large central screen to the left and an additional panel for the front passenger beyond that. It’s a lot.

But once you’re on top of all the glass surfaces, details like open pore grey ashwood trim on the lower console come into focus, as do the brushed metal accents, beautifully sculpted ‘Performance’ front sports seats (optionally fitted to our launch drive example), racy stainless steel pedal covers and the five spoke AMG performance steering wheel with configurable rotary buttons.

It’s a supremely luxurious and comfortable interior. 

The LX came in for a facelift in 2021, perhaps to differentiate it from its Toyota sibling and, according to the press release, “ its level of urban sophistication.” That kind of tells you where this car is going to spend all of its time, doesn’t it?

There’s the new spindle grille that dominates the nose, with some clever detailing to make it look a bit more sporty and dramatic. Around the car there are modified bumpers, skirts, new wheel designs, all that kind of thing. It does look sportier, but there’s no way to hide the visual bulk of such a big unit.

The interior is largely unchanged and the ruggedness is softened somewhat by semi-anline leather trim and alloy sports pedals. It’s terribly conventional and very usable, but there’s none of the excitement or innovation you'll find in other, more recent Lexus cabins.

At over 4.9m long, close to 2.1m wide and a little under 1.5m tall, with a 2961mm wheelbase, the new E53 is a substantial car and feels it on the inside.

Plenty of breathing space for the driver and front passenger thanks in part to the away slope of the screen-dominated dash.

Generous storage, too, with large door bins including enough space for big bottles, a deep lidded box between the seats (which doubles as a centre armrest), a generous glove box and two cupholders under a sliding top at the front of the centre console. 

Hit the second row, and sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, with enough shoulder space for three adults on short journeys. A trio of up to mid-teenage kids will be fine for a road trip.

Storage is pretty handy as well with hefty door bins and two pop-out cupholders in the fold-down centre armrest. No map pockets on the back of the (optional) Performance front seats, though.

Four-zone climate control means there’s individual temperature control for each side of the back seat, with adjustable vents at the back of the front centre console and trailing edge of the B-pillars. Very civilised.

Power and connectivity runs to three USB-C outlets and a wireless device charging pad in the front.

Thanks to the traction battery under its floor, boot volume is restricted to 370 litres (compared to 540L in the conventional E-Class sedan), although there are bag hooks, tie-down anchors and the 60/40 split-folding rear seat is able to liberate more space.

No spare tyre of any description, just a repair/inflator kit, which might make sense for automotive designers and engineers trying to maximise space and reduce weight, but doesn’t make sense for an owner stranded on the side of the road with an unrepairable puncture.

Hellooo?! I think there’s an echo in here. This is one giant car, with eight seats available for the keen or foolhardy to squeeze themselves into. If you’ve got all eight deployed, the boot space starts at a reasonable 349 litres. Kick out the three in the back row and flip them up to the sides of the boot and you have 710 litres, although that figure is slightly down on what it could be as the seats don’t stow neatly away under the floor.

Getting the third-row passengers out is a bit of a chore, because the middle row needs a hefty shove to move, while folding the third row jump seats is a power-assisted affair. The middle-seat passenger in the third row is hugely unlikely to be comfortable no matter their size, but the headroom is good anywhere you choose to sit, and the second row has heaps of legroom.

Scattered throughout are cupholders - I counted seven - and you get bottle holders in the doors. All three rows should be reasonably comfortable, with vents supplying climate-controlled air to each and everyone, and the middle row has its own set of controls.

When you’re knocking on the door of $170,000, “good value” is relative. You’ll be pleased to hear, however, that the LX 570 S is properly loaded. You get 21-inch wheels, air suspension, comprehensive multi-terrain modes should you feel the need to get out amongst it, terrain cameras (with under-car view), variable steering, auto LED headlights, auto wipers, powered tailgate, reversing sensors, reversing camera, clearance sensors, sat nav, head-up display, power front seats, four-zone climate control, heated front seats, wireless phone charging, around-view cameras, sunroof, heated steering wheel, and heated outboard seats in the middle row.

The 12.3-inch screen is big but it’s the old Lexus system, controlled by the weird mixture of touchpad and four-way rocker switch. It’s never been a satisfactory control method and the system itself is a little cumbersome, lacking Apple CarPlay and Android Auto.

The kids in the back should be sorted, though, with an 11.6-inch HDMI-input screen on the back of each front seat, and a set of supplied headphones so that, once the kids are plugged in, you can enjoy the 19-speaker Mark Levinson stereo in peace.

The E53 is powered by a 3.0-litre, turbo-petrol, in-line six-cylinder engine working in concert with an electric motor housed within the car’s nine-speed (torque-converter) automatic transmission. 

Drive goes to all four wheels via an electro-mechanically controlled clutch distributing power between the front and rear axles.

Engine performance is up by around 10kW compared to the previous E53 thanks to software upgrades, a new twin-scroll turbo with higher boost pressure (1.5 bar vs 1.1 bar) as well as additional front and wheel-arch intercoolers. 

The engine alone produces 330kW/560Nm while the permanently excited synchronous motor chips in with a solid 120kW/480Nm for overall outputs of 450kW/750Nm.

The 5.7-litre petrol V8 is classic Toyota/Lexus, unstressed and unhurried, with 270Kw and 530Nm. All of this is harnessed to an eight-speed automatic and an extremely capable off-road setup that almost nobody who buys this car will ever use.

The LX 570 S will tow up to 3500kg braked and 750kg braked.

The E53’s official combined cycle (urban/extra-urban) fuel figure is 1.7L/100km, a spectacularly frugal number for such a high-performance machine. But it’s worth noting it’s predicated on the drive battery being constantly and completely recharged.

Speaking of which, the 28.6kWh, 400-volt traction battery is housed at the rear of the car under the boot floor. It delivers a claimed EV-only range of up to 100km, although that will diminish dramatically if you decide to push up towards the car’s pure-electric top speed of 140km/h.

Important to note the battery’s 21kWh ‘day-to-day’ capacity, designed to keep charge in reserve for any required ‘high-performance boosts’.

An 11kW AC charger is onboard with regenerative braking also harvesting energy, the car automatically selecting the level of recuperation power in line with traffic conditions.

In pure EV mode you can also manually adjust regen through four levels via the steering wheel-mounted transmission shift paddles. 

Auto stop/start for the engine is standard and 98 RON premium unleaded is recommended, although 95 RON is okay at a pinch.

The E53’s official fuel consumption figure and 50-litre tank capacity translate to a range approaching 3000km! But to bring that down to earth somewhat, on the launch drive program, covering urban and mostly highway running, we saw a (dash indicated) average of 6.4L/100km, which equates to a more realistic, but still lengthy, 780km between fills.

The official combined cycle figure of 14.4L/100km is fairly sobering but the real world is even more so - my time with the LX 570 S yielded an indicated 18.5L/100km, which was not unexpected given I spent a lot of time in urban and suburban driving. I don’t think that figure will come as a surprise to any owner of a 2600kg-plus petrol V8-powered four-wheel drive.

The LX 570 S has twin petrol tanks (93 and 45 litres) for a whopping 138-litre capacity to swallow 95 RON fuel, which, on my figures should deliver 745km between fills.

If you’re lining up for a Mercedes-AMG you want an optimal blend of luxury and performance and the E53 Hybrid 4Matic+ nails that delicate balance.

With 450kW (that’s 612hp!) and 750Nm under your right foot, engaging ‘Race Start’, pushing the accelerator to the floor and letting the car do its thing will result in 0-100km/h acceleration in 3.8 seconds. The fat band of mid-range torque is so satisfying to lean into.

Induction, engine and exhaust sounds combine to produce a suitably gruff soundtrack with the hybrid powertrain operating seamlessly. Hit your preferred track day or tempt legal fate and you can explore the car’s claimed (governed) maximum velocity of 280km/h. 

The nine-speed auto is slick and manual changes using the wheel mounted paddles are rapid.  In normal conditions the AWD system is biased to the rear and an electric rear locking diff helps keep things under control if you decide to get the bit between your teeth on a twisting drive.

A chunky brace links the front suspension strut mounts and the car feels predictable and stable in enthusiastic cornering. Rubber is Michelin Pilot Sport 4S (245/35 fr / 275/30 rr) which grips with satisfying determination but does make its rumbling presence felt on anything approaching a coarse chip surface (despite the car’s standard acoustic glass).

Speed-sensitive power-steering delivers accuracy and good road feel without any jitters, the standard active rear-axle steering playing its part. The ‘turning point’ is 100km/h with the rear wheels subtly turning in the opposite direction to the fronts up to that speed and in the same direction beyond it.

‘AMG Ride Control’ combines steel spring suspension (strut front, multi-link rear) with adaptive adjustable damping for the choice of ‘Comfort’, ‘Sport’ and ‘Sport+’ settings. Comfort is the pick for B-road running on typically uneven surfaces. The optional ‘Performance’ sports front seats are comfortable and grippy in equal measure. 

Braking is by ventilated composite rotors all around, with beefy four-piston fixed calipers up front. An electro-mechanical brake booster is designed to combine electrical recuperation with the hydraulic brake for more frequent and efficient energy harvesting over a longer period of time. The pedal feels firm and progressive with smooth initial bite. 

All around vision is good for a conventional sedan with a quality reversing camera, 360-degree overhead view and front and rear parking sensors helping massively with parking duties. That said, a 12.5m turning circle isn’t tiny.

First, some key figures - the LX 570 S is 5.08 metres long, 1.98 metres wide and 1.87 metres tall, depending on the height you’ve set the air suspension. It is Quite Large. Yes, cars like the Mazda CX-9 are as long and the Hyundai Palisade is nearly as tall, but given the LX’s humble origins, it just feels really, really big, and it looks it, too.

That feeling is not helped by oddly heavy and slow steering. The latter quality is a result of its off-roading abilities, but you can’t help but wonder if the variable-ratio steering couldn’t be made a bit quicker for town use. The S in the 570 S also adds sportier dampers front and rear, which do the ride quality few favours. Smooth roads are fine, of course, but concrete roads induce a weird porpoising movement that some air-suspended Land Rovers get, and it’s not particularly pleasant, although if you don’t use one of those roads, you won’t notice.

It's obviously a tricky machine to park and get around tight inner-city back streets. Our narrow suburban street posed a challenge when turning in and out of our narrow driveway with cars parked either side. And I did wonder about the strength of our driveway, given the heft of the LX.

I'm not going to pretend I enjoyed driving the LX, but it’s not bad to drive. You’re always aware of the sheer size and weight of the thing, though, as well as the conspicuous consumption of the very smooth and very agreeable V8. The engine does its best to shift the huge weight and the transmission is beautifully calibrated.

Once you’re on a motorway, progress is quite regal, too, so trips away in the LX will be supremely comfortable, even if you hit the busted-up dirt roads I accidentally ended up on. 

The LX has 10 airbags, ABS, stability and traction control, forward AEB (with pedestrian detection), auto high-beam, lane-departure warning, blind-spot monitoring, rear cross traffic alert and trailer-sway control.

The LX does not have an ANCAP safety rating. Its LandCruiser twin was last tested in 2011, so that’s not exactly relevant, given the huge rule changes and improvements in safety equipment since then.

The Mercedes-AMG E53 Hybrid 4Matic+ is covered by a five-year/unlimited km warranty with the high-voltage battery covered for eight years/160,000km. Those terms match the key players in the premium and luxury parts of the market.

Mercedes-Benz ‘Road Care’ assistance is included for the duration of the main vehicle warranty. 

Maintenance is recommended every 12 months/25,000km, with service plans offered across three- ($4110), four- ($5410) and five-year ($7570) periods. That’s an average of around $1350 for the first two and $1500 for the last one. That added powertrain complexity obviously has an impact in the workshop.

Lexus offers what I think is a unique four-year/100,000km warranty along with four years' roadside assist.

Capped-price servicing weighs in at $495 per service, almost $3000 over six services, and you'll be back at the dealer every six months or 10,000km before leaving with a loan car. Or the dealer will come and fetch the car from you and then return it freshly cleaned. Nice.

LX owners also get access to Lexus Encore Platinum . This generous program includes Lexus on Demand (you can book another Lexus - such as an LS or an RC F if you’re feeling racy - four times per year at some airports or dealers) and eight valet parking vouchers for some Westfields and Chadstone in Melbourne, all booked through the Encore app. There’s also a bunch of benefits inherited from the standard Encore program.
