Lexus ES250 vs Mercedes-Benz S600

What's the difference?

Since day one Lexus has aimed to prise buyers away from the limpet-like grip of traditional luxury car players. Conventional marketing wisdom says consumers buy brands, with the actual product a secondary consideration. 

The updated ES has the value, efficiency, safety, and driving refinement to again challenge the establishment. Amazingly, the ownership package, specifically the warranty, is starting to lag the market. 

But for open-minded premium buyers this product is worth a look before following a well-worn brand path. And if it was my money, the ES 300h Luxury with Enhancement Pack is the range sweet spot for value and performance.

The 2018 Mercedes-Benz S-Class remains a technological tour de force, a luxury sedan to be reckoned with - one that has safety, technology, comfort, finesse and performance all rolled into a stylish package. 

It's hard to see why you'd need anything more than the S 350 d, which is now much more attractively priced. It'd be my pick, but I'd have to get the Energizing Comfort Control package, and probably the AMG styling pack, too. And even then it would cost less than its predecessor.

From shy wallflower to life of the party, the Lexus ES was given a comprehensive design makeover for its seventh generation.

A dramatic, angular exterior incorporates signature elements of the Lexus brand's distinctive design language including an unmissable ‘spindle grille’, but is still clearly recognisable as a conventional 'three-box’ sedan.

The jagged headlights now feature ‘tri-beam’ LEDs on F Sport and Sports Luxury grades, adding an extra air of purpose to an already bold face. And the grille on Luxury and Sports Luxury models is now made up of multiple L-shaped elements, mirrored across the top and bottom sections, then finished in gunmetal grey for a close to 3D effect.

The ES is offered in 10 colours - ‘Sonic Iridium’, ‘Sonic Chrome’, ‘Sonic Quartz’, ‘Onyx’, ‘Graphite Black’, ‘Titanium’, ‘Glacial Ecru’, ‘Radiata Green’, ‘Vermillion’ and ‘Deep Blue’ with two other shades reserved for the F Sport only - ‘White Nova’ and ‘Cobalt Mica.’

Inside, the dash is a mix of simple sweeping surfaces contrasted by a flurry of activity around the centre stack and instrument cluster.

Located roughly 10cm closer to the driver, the new multimedia screen is a 12.3-inch unit with touch functionality, a welcome alternative to the laggy and inaccurate Lexus ‘Remote Touch’ trackpad set-up. Remote Touch remains, but my advice is to ignore it and use the touchscreen.

The instruments sit in a deeply hooded binnacle with buttons and dials on and around it. Not the sleekest design in the segment and passable only from an ergonomic point-of-view, but the overall feel is suitably premium.

I swear it has been facelifted, and the changes are bigger than they might appear. There is no doubt that the S-Class shape is largely unchanged, but the German company has kept the modifications minimal in the scheme of things.

That doesn’t mean those changes are unnecessary, though. The new headlights, for example, are standard on every model, and are constructed with 84 LEDs (including three for the daytime running lights), and of course they’re adaptive with automated high-beam - meaning they’ll shield other road users from the glare of the lights at night. And the lights themselves will throw a main beam up to 650 metres, according to the company. 

Other things are slightly more cosmetic, like the revised three-bar grille treatment, new front and rear bumper designs that feature broader sculpted sections to widen the stance of the car, and there are new LED tail-lights as well.

The smallest set of wheels used to consist of 18-inch rims, but now the base car rolls on 19s, while the rest of the expansive range sits on 20s. 

The inside has seen some changes, too, but the appearance of things in the cabin isn’t the focal point - its the usability of the technology that's the big change. 

Oh, but I should tell you there are now 64 ambient lighting colours to choose from, which is up from seven, and now you can also set the lighting in three different zones - so theoretically you can have blue, orange and green areas of the cockpit, if you’re gross.

An overall length just under 5.0m long shows how much the ES and its competitors have crept up in size over recent generations. The Merc C-Class is more a mid-size car than the compact sedan it once was, and at nearly 1.9m wide and standing a bit over 1.4m tall the ES more than matches it for space.

There's plenty of room up front, the car feeling open and spacious from behind the wheel, thanks in part to the low sweep of the dash. And the rear is just as commodious.

Sitting behind the driver's seat set for my 183cm (6'0”) position I enjoyed good leg and toe room, with more than enough headroom, despite inclusion of a tilt and slide glass sunroof on all models.

Not only that, entry to and egress from the rear is a breeze thanks to a large aperture and wide opening doors. And while the back seat is best for two, three adults across is do-able without too much pain and suffering for short to medium journeys.

Connectivity and power options are plentiful with twin USB ports and a 12-volt socket front and rear. And storage starts with two cupholders in the front centre console, and another pair in the fold-down rear centre armrest.

If the remote touch system was (deservedly) given the boot, there would be room for extra oddments space in the front console.

The front door pockets are adequate rather than large (smaller bottles only), the glove box is modest, but the storage box (with padded armrest lid) between the front seats is more generous.

There are adjustable air vents for rear passengers, which you'd expect in this category, but are always a plus none-the-less.

The rear door pockets are okay, except the opening is relatively slim so bottles are a struggle, but there are map pockets on the back of both front seats as another bottle option.

Important to note that while boot space is decent at 454 litres (VDA) the rear seat doesn't fold. At all. A lockable ski port door sits behind the rear armrest, but the lack of a split-folding back seat is a significant practicality compromise.

A reasonably high loading lip into the boot isn't great, either, but there are tie-down hooks to help secure loose loads.

The Lexus ES is a no-tow zone and a space-saver spare is your only flat tyre option.

If you’re buying a Mercedes-Benz S-Class there’s a good chance you’re more interested in the back seat than the front: you could be buying it for a business, or you could like to be driven around - and there are definitely worse places you could be.

We would suggest, though, that the best place you could be if that’s your caper is in the back of a long-wheelbase S-Class model, which has extra legroom. 

And if you happen to be in a LWB model with the 'Business Class Package', you’ll enjoy two individual rear seats rather than a three-seat bench, folding tables for your bento box or laptop, and an ‘executive seat’ on the passenger side that features a foot rest and allows you to slide the front seat forward to liberate more room. Deluxe. 

No matter if you are in one of the stretched models demarcated as such by the ‘L’ suffix or not, you will enjoy excellent seat comfort and good head- and shoulder-room. Legroom in the regular models isn’t as plentiful as you might expect: much more affordable cars like the Hyundai Sonata give the S-Class a run for its money in that regard.

There are good storage options for odds and ends, with the back seat featuring a fold-down armrest with pop-out cupholders and a storage box, as well as map pockets - and the boot space varies depending on the model, but the S 350 d has a 510-litre cargo capacity (VDA). All four doors have bottle holsters, and a bit of extra room besides. Of course there are rear-seat air-vents, and if you’re kids are lucky enough to ride around in a S-Class, the two ISOFIX/three top-tether points will be welcome.

Up front there are two cupholders between the seats, and a new wireless phone charger in the centre console (Qi compatible phones only). There are two USB ports as standard in most models, while models with the rear seat entertainment package fitted get rear USBs. 

The huge screen that runs across two-thirds of the dashboard has seen the noticeable join marker removed for this update, with the monitors being upgraded to a higher resolution and the graphics have been reworked, too. The codpiece-style controller of the Comand media interface remains, and while it still isn’t as simple as other controllers, it is reasonably easy to get used to. 

So … what about Beyonce? 

She comes in as part of the Energizing Comfort Control system, which is standard in some models and a $1400 option in those that don’t have it fitted. 

Essentially it allows you to choose between different set moods: 'Joy', 'Freshness', 'Vitality', 'Warmth', 'Comfort' and 'Training', the latter of which offers three different stretching/exercise programs that last for 10 minutes to stop fatigue. The instructions are given by voice over the sound system.

Each of the moods will adjust the temperature and ventilation (the Freshness setting offers ‘gusts’ of fresh air as if you’re at the beach!), ambient lighting, air fragrance and intensity, and the massage function for the seats. And the music bit - there are predefined songs the system can cue up to suit the mood, or it can identify songs on a hard-drive or USB that suit the programs by analysing the tempo of the tune. Amazing, right?

The new steering wheel looks a lot sportier than the one in the pre-update car, and it has finally done away with the awkward cruise control stalk in favour of steering wheel buttons for the adaptive cruise control system.

If you can call a car that starts near two-hundred grand good value, then you have much more money than I do. But there is no escaping it: the new S-Class 2018 range is better value than before.

The starting point in the range is entry-grade S 350 d, which is $195,900 plus on-road costs. 

Standard kit for that model includes 19-inch alloy wheels, leather trim, heated and cooled front seats, nappa leather-wrapped steering wheel, those great new headlights and the new ambient lighting system, a panoramic sunroof, head-up display, dark brown 'Eucalyptus' trim, auto-dimming rear-view and side mirrors, a wireless phone charging system, keyless entry and push-button start. The entire S-Class range now gets auto-closing doors and an electric boot lid, too.

The media system in the S 350 d includes sat nav with traffic monitoring, a 13-speaker Burmester sound system, digital TV, DAB+ digital radio, Apple CarPlay and Android Auto, and the 'Comand Online' system with internet capability.

Next up the model range is the S 400d L (at $222,500), and the S 450 L ($227,500) - both of which are specified identically. Over the base model car they feature the extended wheelbase, as well as electronically adjustable rear seats with memory function, side window blinds, a rear blind, rear climate control, and 20-inch wheels. 

The S 560 sees the price head north to $270,000 (for the short-wheelbase model, which loses the abovementioned stuff in the L models), or $295,000 for the S 560 L. It adds the following nice features: nappa leather, brown burr walnut trim, a wood/leather steering wheel, 'Energizing Comfort Control', different (five-spoke design) 20-inch wheels, laminated glass and an anti-theft protection package. The S 560 L has luxury rear head restraints - they’re more like pillows, honestly - an individual rear-seat entertainment system and two wireless headsets.

The top of the regular S-Class model range is the Mercedes-AMG S 63 L, which is a princely $375,000. It builds on the kit offered in the models below, and pushes the sports luxury aspect further, with a full AMG body kit, 20-inch AMG wheels, AMG specific drive programs, AMG brakes, an uprated exhaust, sports steering and retuned suspension. Inside there are model-specific elements, special wood trim, front seats with active bolstering, and heated and ventilated rear seats.  

If you’re shopping at this end of the market, then you’ll likely also be tossing up between a BMW 7 Series, or maybe a Bentley Flying Spur. An all-new Lexus LS will arrive in April 2018, and the all-new Audi A8 isn’t far away, either.

The ES 250 is powered by an all-alloy, 2.5-litre, naturally aspirated (A25A-FKS) four-cylinder engine featuring DVVT (Dual Variable Valve Timing) - electrically actuated on the intake side, and hydraulically on the exhaust side. It also uses a combination of direct and multi-point fuel-injection (D-4S).

Maximum power is a handy 152kW at 6600rpm and peak torque of 243Nm is available between 4000-5000rpm, with drive going to the front wheels via an eight-speed automatic transmission.

The 300h features a modified (A25A-FXS) version of the same engine using the Atkinson combustion cycle which plays with valve timing to effectively shorten the intake stroke and lengthen the expansion stroke.

The down-side of this set-up is a loss of low-end power, while the up-side is improved fuel efficiency. Which makes it perfect for a hybrid application where an electric motor can make up for the low-end shortfall.

Here, the result is a combined output of 160kW, with the petrol engine producing its peak power (131kW) at 5700rpm.

The 300h's motor is a permanent magnet synchronous type producing 88kW/202Nm, and the battery is a 204-cell nickel-metal hydride type with a capacity of 244.8 volts.

Drive again goes to the front wheels, this time via a continuously variable transmission (CVT).

The big news for the majority of S-Class buyers is the new engine in the S 350d, which is a 2.9-litre in-line six-cylinder turbo-diesel with 210kW of power and 600Nm of torque. It has a nine-speed automatic and is rear-wheel drive (RWD).

That same diesel engine is wicked up in the S 400d L, with that model churning out 250kW and 700Nm, and remains rear-drive with a nine-speed auto.

The petrol model range is opened by the S 450 L with a 3.0-litre six-cylinder twin-turbo mill producing 270kW/520Nm. Again, nine-speed auto, RWD.

The S 560 and S 560L run the same 4.0-litre twin-turbo V8 petrol with 345kW of power and 700Nm of torque. Nine-speed auto, rear-drive - naturally!

The AMG-fettled S 63 has a thumping twin-turbo 4.0-litre V8 petrol engine with 450kW and 900Nm, with a nine-speed MCT multi-clutch auto and - you guessed it - RWD.

Hyundai's official fuel economy figure for the ES 250, on the ADR 81/02 - urban, extra-urban cycle, is 6.6L/100km for the Luxury and 6.8L/100km for the F-Sport, the 2.5-litre four emitting 150 and 156g/km of C02 (respectively) in the process.

The official combined cycle fuel economy figure for the ES 350h, is just 4.8L/100km, the hybrid powertrain emitting only 109g/km of C02.

While the launch program didn't allow us to capture real-world (at the bowser) figures we did see a dash-indicated average of 5.5L/100km in the 300h, which is brilliant for a car in this class, weighing in at 1.7 tonnes.

You'll need 60 litres of 95RON premium unleaded to fill ES 250's tank and 50 litres to brim the ES 300h. Using Lexus figures that equates to a range of a little less than 900km in the 250 and just over 1000km in the 350h (900km using our dash-indicated number).

To further sweeten the fuel economy equation Lexus provides an Ampol/Caltex five-cents-per-litre discount as a permanent offer via the Lexus app. Nice.

The diesel models are - unsurprisingly - the most frugal in the range, with the entry-level S 350 d using a claimed 5.4 litres per 100km across a range of disciplines.

The S 400 d L - which uses a higher-output version of the same diesel drivetrain as the model above - uses only a minuscule amount more: its claim is 5.5L/100km. 

The most frugal of the petrols is the S 450 L, with its six-pot petrol twin-turbo using a claimed 8.4L/100km.

Every model has stop-start - including the AMG - and the V8 petrols also feature cylinder deactivation when in 'Eco' mode.

That cylinder deactivation system helps the S 560 achieve an incredibly low claimed consumption of 8.5L/100km. So does the longer, slightly heavier S 560 L.

The higher-out Mercedes-AMG S 63 L uses 9.0L/100km, according to its claim. Amazing for the outputs of the engine.

The first thing you notice behind the wheel of this ES is how extraordinarily quiet it is. Sound absorption materials are stuffed all around the body. Even the engine cover has been designed to keep the decibels down.

And ‘Active Noise Control’ (ANC) uses the audio system to generate “noise-cancelling waves” to suppress mechanical clatter from the engine and transmission. The car is eerily EV-like in it's pin-drop interior tranquility.

We focused on the ES 300h for the launch drive, and Lexus claims 0-100km/h 8.9sec for this version of the car. It feels every bit that quick, but the engine ‘noise’ and exhaust note are like the humming of a distant bee hive. With thanks to Daryl Kerrigan, how's the serenity?

Around town the ES is composed and supple, absorbing pock-marked urban irregularities with ease, and on the freeway it feels like a hovercraft.

Lexus makes a lot of noise about the torsional stiffness of the ‘Global Architecture-K’ (GA-K) platform sitting under the ES, and it's clearly more than hot air. Through twisting B-roads it remains balanced and predictable.

Even in non-F-Sport variants the car points nicely and will steer accurately on the throttle through constant radius corners, with only modest body roll. The ES doesn't feel like a front-wheel drive car, with neutral handling up to an impressively high limit.

Luxury and Sports Luxury grades are offered with three drive modes - ‘Normal’, ‘Eco’ and ‘Sport’, tweaking engine and transmission settings for economy or a more spirited drive.

ES 300h F Sport variants add three more modes - ‘Sport S’, ‘Sport S+’ and ‘Custom’, further revising engine, steering, suspension and transmission characteristics.

Despite all the tuning options, road feel is not the ES's strongest suit. Dialing in sportier modes will add steering weight but no matter what the setting, the connection between the front wheels and the driver's hands is less than intimate.

The CVT auto suffers some of that disconnect between road speed and revs, the engine moving up and down the rev range in search of the power/efficiency sweet spot. But wheel-mounted paddles allow for manual shifting through pre-set ‘ratio’ points, and that option works nicely if you prefer to take the reins.

And when it comes to slowing down the ‘Auto Glide Control’ (ACG) system smooths out regenerative braking when you're coasting to a stop.

The conventional brakes are ventilated (305mm) discs at the front and a solid (281mm) rotor set-up at the rear. Pedal feel is progressive and outright stopping power is strong.

Random notes: The front seats are great. Super-comfortable yet neatly bolstered for secure location. The F Sport's chairs, even more so. The new multimedia touchscreen is a winner. It looks good and menu navigation is agreeably straight forward. And the digital instrument cluster is similarly clean and clear.

Smooth. It wasn’t even because I’d chosen the Energizing Comfort Control mood to elicit that vibe. It’s smooth - and so it should be.

Whether it’s the near-silent new six-cylinder diesel, which hauls the near two-tonne sedan along with less fuss than a medical centre receptionist dealing with a room full of coughing patients. There is no fuss. You just hand over control to the engine, and trust it will get you where you need to be.

The V8 petrol in the S 560 also has a bit of a silent killer vibe to it. There’s perhaps not as much noise as a V8 fan might want, but the mumbo is there, and in both cars the gearshifts are sublimely timed and super smooth.

Admittedly, the stiff-sided run-flat tyres on both the 19- and 20-inch wheels can exhibit a slight terseness over sharp edges, but when it comes to rolling over pockmarked surfaces or rougher country backroads, the ride offered up by the air suspension with variable dampers is superb. Put it in Sport mode and it stiffens up to the degree you’d expect, but Comfort is no doubt the best place to be.

The steering is super light but accurate, meaning it’s easier than you’d think to pilot this behemoth of a sedan through corners. The grip on offer is excellent, too, even if traction can be an issue - I had a full couple of seconds of strobe light action from the traction control light when I buried the throttle in the S 560. 

I didn’t get a chance to drive the six-cylinder petrol S 450 L, or the S 400 d L. And, I’m really sad to report, there was no opportunity to drive the AMG S 63 L, either. 

But the overall feeling of the updated range is that it remains a deluxe and delightful limousine - whether you have the good fortune of being in the driver’s seat or not.

Easily one of the safest cars, if not the safest car, on the road today if technology is anything to go by. Well, we can’t go by a crash test score, because the S-Class hasn’t been crashed by EuroNCAP or ANCAP. So I can’t really give it a 10/10 for safety…

But when the standard safety kit list is as lengthy as the S-Class’s, it seems a safe bet. Items fitted include a 360-degree camera system, parking sensors front and rear, auto emergency braking, active blind-spot monitoring, active lane-keeping assist, adaptive cruise control with active steering assist, drowsiness detection, crosswind assist, and pedestrian detection with evasive steering assist (which allows you to turn the wheel harder to avoid impact with a pedestrian).

Plus there are other items like the company’s Pre-Safe crash detection system which can flash the car’s hazard lights at other road users, and tighten the occupant’s seatbelt in anticipation of being hit. And if that happens, there are eight airbags (dual front, front side, rear side, curtain).

From the time it arrived in the Australian market just over 30 years ago Lexus has made the ownership experience a key differentiator for the brand.

Its focus on post-purchase benefits and ease of servicing shook the established luxury players out of their button-backed leather lounge slumber and into a new aftersales mindset.

That said, the Lexus standard four-year/100,000km warranty is some way off luxury newcomer, Genesis, as well as traditional heavyweights Jaguar and Mercedes-Benz, all at five years/unlimited km.

Yes, Audi, BMW and others are at three years/unlimited km, but the game has moved on for them, too. Plus, the mainstream market standard is now five years/unlimited km, with some at seven, even 10 years.

On the other hand, the ‘Lexus Encore Privileges’ program provides 24-hour roadside assistance for the duration of the warranty, as well as, “dining, hotel partnership and luxury lifestyle experience offers exclusive to owners of new Lexus vehicles.”

The Lexus Enform smartphone app also offers access to everything from real-time advice on events and the weather to nav destinations (restaurants, businesses, etc), and more.

Service is scheduled every 12 months/15,000km (whichever comes first), and the first three (capped price) services for the ES are $495 each.

A Lexus loan car is provided while your pride and joy is in the workshop, or a pick-up and return option (from home or office) is available. You'll also receive a complimentary wash and interior vacuum.

Mercedes-Benz offers a standard three-year/unlimited kilometre warranty.

Servicing is due every 12 months or 25,000km on all engines except AMG drivetrains, which require servicing every year or 20,000km. 

Mercedes-Benz has a (pricey!) capped-price servicing plan. The standard diesel and petrol models in the S-Class range cost $596 for the first service, and $1192 for the second and third visits. The costs for the sole AMG model is $736 for the first service, then the second and third visits are $1472 per.
