Lexus ES350 vs Mercedes-Benz E-Class

What's the difference?

The ES300h is outstanding in terms of ride comfort, refinement and value. If you’re looking for a true driver’s car then a Lexus RCF is probably a better tree to bark up, but if you’re looking to ferry passengers in a serene, prestigious and fuel-efficient way, then look no further.

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.

If you think all Lexus models look the same, then pop on over to the Audi, BMW or Benz websites and take a peek at their line-ups. Compared to the ranges from those prestige car makers, Lexus models look wildly different from each other.

Opinions on that ‘Spindle Grille’ are as polarising as views on politics or religion. Personally, I like how upfront and brave the grille design is, but what seems odd to me is that it’s almost as if this was the only place on the exterior where designers were allowed to be a bit adventurous. The rear, while cleanly styled is a bit plain. The bottom just doesn’t match the face.

The ES300h’s roofline in side profile is beautiful as it sweeps almost fastback-style to the boot lid. Again, not the most dramatic styling, but it’s still pleasing in the sense that the design flows well together. The same can be said for the fit and finish – the panel gaps are near-perfect.

This perfection continues into the cabin, where the materials and craftsmanship matches German prestige rivals in places (the door handles, leather and digital instrument cluster, for example), only to be let down in other areas which disclose its budget Toyota family connection (the air vents, steering wheel and display screen).

The ES300h’s interior design isn’t going to set everybody’s world on fire, but there will be those who adore its asymmetrical styling with different textured surfaces that fold, swoop and jut up against each other’s space. Have a look at the images, they’re of the Sports Luxury which sits above the Luxury in the two grade line-up.

The differences visually between the grades is minimal. The Luxury has 17-inch alloys, while the Sport Luxury has 18-inch.

New colours for this generation include Glacial Ecru (the sandy hue of our test car in the images) and Radiata Green. Both grades’ interiors come in a variety of colour schemes, including Black, Chateau, and Topaz. Exclusively for the Sport Luxury cabin is Rich Cream, too. The Sports Luxury steering wheel has wood trim.

One of the more peculiar design elements of the ES300h’s cabin design, and there are a few, are the controls for the drive modes and traction control. They sit like horns on the instrument cluster hood, as though these are things the driver will constantly be reaching for, when in reality most people will never touch the traction control button.

A new-generation car means new foundations, and the ES300h is built on the GA-K platform which underpins the Camry. The platform is part of the latest global architecture which Toyota and Lexus are now using to build its vehicles.

The dimensions of the ES300h, if you’re wondering if it will fit in your garage, are just under 5.0m long, 1.9m wide and 1.4m tall.

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 Lexus ES300h is a five-seater sedan, but it’s really designed to sit two comfortably in the back, given there’s a large driveshaft hump in the floor and that the outboard seats are divided by a fold-down control panel/armrest.

Legroom in the second row is ample. I’m 191cm tall, and I had about 20mm of space between my knees and the seat back when it was in my driving position. Headroom gets tight with that sloping roofline, but there’s just enough space thanks to the low hip point of the rear seats.

Cabin storage is excellent. The fold-down armrest for the rear seats has a storage tray and two cup holders, while the large centre console bin has a lid which can open towards the driver and also to the front passenger (I spent way too long marvelling at how it worked). There are two cup holders up front and decent-sized door pockets, too. Those rear doors open wide for easy exit and entry.

Boot space in the ES300h is 454 litres (VDA), beating the 410-litre cargo capacity of the BMW 530e.

As far as power outlets, you’ll find two USB chargers in the centre console storage bin and a Qi wireless charging pad, which is awkwardly situated making it hard to place larger phones onto it.

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.

Priced at $199,900, before on-road costs, the Mercedes-AMG E53 Hybrid 4Matic+ lines up against an interesting mix of internal combustion, hybrid and pure-EV contenders, the most closely aligned on spec and price being the BMW M4 M Competition xDrive ($201,300), Lexus LS500h F Sport ($199,250) and Porsche Taycan 4 Cross Turismo ($197,400).

And as you’d expect for a performance sedan on the cusp of $200K the standard equipment list is long. Aside from the performance and safety tech we’ll get to shortly, the E53 features four-zone automatic climate control, 17-speaker Burmester surround sound audio (including digital radio), Nappa leather trim (including the steering wheel) and the ‘MBUX Superscreen’ display consisting of three screens - 14.4-inch central media, 12.3-inch instrument/info for the driver and 12.3-inch for the front passenger.

You can also tick off the box on Android Auto, Apple CarPlay and Bluetooth connectivity, plus the power front seats (with memory) are heated.

There’s also a head-up display, panoramic sliding sunroof, ambient lighting, keyless entry and start, built-in nav, a 360-degree virtual top-down camera view, LED exterior lighting and 20-inch alloy rims. 

There’s more, but you get the idea. This car is loaded with included features that help it match or better its diverse competitive set.

There are four optional AMG packages available - The ‘Night Package’ ($3000) which includes aero-influenced body elements, special rims and more. The ‘Carbon Fibre Package’ ($6000), featuring a range of carbon bits including the exterior mirror caps, bootlid spoiler and interior pieces like the centre console and steering wheel. A ‘Performance Seat Package’ ($5000), which unsurprisingly focuses on racier front seats with integrated headrests. And the ‘Energizing Package Plus’ ($5300) adds ‘multicontour’ front seats that are heated (as are the centre console lid and door armrests) and individual fragrance for the interior, as well as ionisation of the cabin air.

As mentioned at the start of this review, in Australia the Lexus ES is only available with one powertrain variant – a petrol-electric hybrid.

This combines a 2.5-litre four-cylinder petrol engine making 131kW and 221Nm, with an electric motor that has an output of 88kW and 202Nm. The 244.8V nickel-metal hydride battery has been moved from under the boot floor in the previous generation car to under the rear seats, so it no longer eats into the cargo space.

The ES300h isn’t a plug-in hybrid, so battery recharging is done through regenerative braking.

A continuously variable transmission means seamless and smooth low-speed driving using just the motor, but under heavy acceleration the engine activates and you’ll hear that drone associated with CVTs.

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.

This is the point of a hybrid, right? To save fuel? The electric motor can power the car at low speeds around car parks or in bumper-to-bumper traffic, and I found that after 104km of both urban and open road usage my fuel economy in the Sport Luxury was 5.4L/100km.

Lexus’ official combined fuel economy figure for both the Luxury and Sports Luxury is 4.6L/100km.

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.

Two words: quiet and comfortable. Well that’s three words, but that sums up the ES300h on the road. Yes, rivals may have intelligent adaptive air suspension and leather made from free range cows, and they are supremely tranquil and sumptuous places, but challenging them is this ES300h.

Even with its regular shock absorbers and steel-spring suspension, the ride was outstanding for its comfort and composure on the worst roads Sydney could throw at it over the week we tested the car.

Front and rear seats were supportive and comfortable over long distances, too. From a driver’s perspective the experience was serene – this was an easy and relaxing car to pilot.

I’m not a huge fan of petrol-electric hybrid powertrains, but it suits the seamless personality of the ES perfectly, adding to the smoothness of the ride as it slipped silently through traffic.

Just don’t expect the ES300h to be rewarding from a dynamic driving perspective. The steering was heavy and a little numb, and while the handling was good, I felt disconnected from the road. And whenever I needed to move quickly the combustion engine would splutter to life and the CVT would begin to drone.

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.

The Mercedes-AMG E53 Hybrid 4Matic+ hasn’t been assessed by ANCAP or Euro NCAP, but that doesn’t mean it comes up short in terms of crash-avoidance and passive safety tech.

It features a comprehensive suite of ‘Advanced Driver Assistance Systems’ (ADAS) features including ‘Active Brake Assist’ (Merc-speak for AEB), adaptive cruise control, blind-spot monitoring, lane-change and lane-keeping assist, front and rear cross-traffic alert, traffic sign recognition, driver attention monitoring, adaptive high-beam, ‘Park Assist’ (including front and rear parking sensors) and tyre pressure monitoring.

And if an impact is unavoidable the airbag count runs to 11 - dual front, front and rear side, full-length side curtains, driver and front passenger knee and a front centre bag.

As the name implies, ‘Auto Emergency Call’ will contact emergency services after a collision and there’s even the obligatory Mercedes first aid kit and high-vis vests. 

There are three top tethers for child seats or baby capsules across the rear seat with ISOFIX anchors on the two outer rear positions.

The ES300h is covered by Lexus’ four-year/100,000km warranty. Servicing is recommended every 15,000km or 12 months. There is no capped-price servicing scheme.

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.
