Mercedes-Benz CLA-Class vs Lexus ES

What's the difference?

The broadening of the CLA’s scope in this third-gen version puts it a step ahead of key rivals and raises the compact sedan’s prominence in the three-pointed star’s local line-up. Its combination of quality design, performance and efficiency is compelling. And we’ll drive the battery-electric version as soon as it lands.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

There’s no denying the Sport Luxury is imposing, spacious, plush, chock-full of kit, efficient, speedy and pleasingly relaxing up to a point.

But its interior is also dated and true ride comfort can be elusive beyond smooth roads for this top-of-the-line version to make the grade as a proper luxury sedan.  

The ES 300h feels more like an aspirational Toyota than a Lexus for the (wealthier) masses, especially after recent triumphs like the latest NX and RX SUVs. The Camry DNA is difficult to disguise, as the amused strangers who sat in our test car uninvited thinking it was their Camry highlights.

Sure, the hybrid is no Chevy V8, but in many other ways, the Sport Luxury seems like the modern successor to the Holden Caprice experience.

In an impressive feat of aero fine-tuning Mercedes-Benz design and engineering teams have managed to make an already slippery car even more efficient with this new CLA dropping the car’s drag-coefficient from 0.23 to an amazing 0.21.

The sloping, coupe-style profile remains as a CLA signature, complete with frameless doors, flush door handles and aero wheels. 

Hybrid variants sport a conventional radiator grille decorated with a Mercedes-Benz star pattern in chrome and illuminated around its perimeter, while the EVs feature a fully illuminated LED grille display.

And in a move perilously close to branding overkill, the three-pointed star motif is carried into the headlights and tail-lights.

For Latin buffs the interior treatment is minimus extremus, the multi-screen ‘MBUX’ array in the CLA220 we drove dominating the front part of the stripped-back cabin.

From an ergonomic point-of-view, there are no physical controls for ventilation and the only non-digital audio control is on the steering wheel.

But aesthetically, the cabin is clean and simple with touches like ‘floating’ door armrests and a gently rounded front centre console adding to an overall relaxed atmosphere.

Historically, cars like the ES appeal to an older and more conservative demographic, who value imposing, conspicuously-expensive looking sedans offering the luxury of space. This is the Cadillac model and our Lexus embodies it.

Which is why hire company operators snap such vehicles up. Great for airport-hotel-airport runs.

But it’s weird, given how much of Lexus’ design language is in the ES’ elaborate nose and tail treatments, how generically Toyota this looks. Certainly, our test car’s 'Sonic Quartz' white paint job does not help.

Just to reinforce this perception, two strangers were fully sat inside our unlocked test Lexus before they realised it wasn't their actual car parked nearby – a white Camry of course.

How they laughed. But if I had paid over $80K for my ES, I certainly wouldn't be amused.

At just over 4.7 metres long the CLA isn’t a million miles away from full C-Class length and interior space is generous. In fact, there’s an extra 16mm in height and 12mm in width compared to the model this car replaces.

And in terms of storage there are generous bins in the doors with room for bottles and you can place them in one of the two cupholders in the centre console.

There’s the obligatory bin between the seats, a bay here for wireless device charging and a glove box, plus an extra storage bay under the flying buttress-style console.

In the back seat sitting behind the driver’s seat, set for my 183cm position and there’s plenty of footroom as well as acres of legroom and headroom. 

And part of that is the immense panoramic roof which is covered in all kinds of high-tech coatings to make sure all the light comes through but none of the heat.

Then for storage, again you’ve got bins in the doors with room for bottles as well as a pull-down armrest between the seats with three cupholders in it (one espresso-sized) and drive slot in front of them.

There are netted map pockets on the front seatbacks, individual vents which are always welcome and a couple of USB-C charging ports to keep devices charged.

Boot volume is rated at 405 litres (VDA) and the rear seatback folds 40/20/40 to liberate more storage space if required. And there’s a 101L front boot on electric models. 

There’s a hands-free tailgate on the 220 Hybrid. A 1.6- to 1.8-tonne braked trailer towing capacity is handy, but the fact there’s no physical spare tyre isn’t. Your only option in the case of a flat is an inflator and puncture sealant kit. Not good enough.

The ES 300h may look like a gussied-up Camry on the outside, but there’s very little evidence of the Toyota inside the stretched cabin, with Lexus-specific seating, trim and dashboard.

However, if you’re familiar with the latest LS, NX or RX models, much of what you see is now dated, previous-gen tech, and that’s an issue in some key ways.

Let’s start with the SL positives, though.

Quiet and free from rattles, the interior is defined by its first-class fit and finish, and then closely followed by the vast length inside, with ample room up front to stretch out and relax in. The ES’ substantial width adds to the sense of spaciousness.

Ventilation is excellent, exemplary even, with strong and effective climate control all around the car. Great for very hot days.

The front seats provide practically infinite adjustment in most directions, and include a handy thigh-support extender that – like everything else inside – moves electrically.

Comfy and supportive, they do a fine job. Effective heated and vented cushions and backrests are further bonuses.

But let's call out the hard front headrests. They feel cheap. And the ES’ age now shows in other, eyebrow-raising ways for an $80K-plus machine.

The dash is a messy mix of now-dated Lexus styling cues – from the ugly asymmetrical centre console to the single circular instrumentation dial for speed and tachometer.

The original IS 200's analogue watch face theme was cool in '99. Today's iteration looks basic.

Storage seems poorly judged given the vastness of this sedan, provided for by cavities in the sub-sized centre armrest, glove box and door bins. Note that the latter cannot hold bottles.

Then, there’s the ill-conceived touchpad that requires brain-surgery precision when fingered to navigate the main display screen when driving (though now it's also a touchscreen, and not before time); after years of various iterations of this, it remains alien and confounding in the extreme to operate. Rest assured, it's been banished in newer-gen Lexuses.

Also annoying is the infernal ‘please obey all traffic regulations’ voice warning, just like you find in a Yaris; the limited and easily-flummoxed voice-control tech and the dated and low-fi graphics for the needlessly complicated sat-nav system.

We relied on CarPlay because the in-built item endlessly let us down. Chuck them all out.

However, there are upsides to a dated interior, because even though this is a confusing and at-times intimidating button-fest, it’s still preferable to the today's everything-behind-a-touchscreen mania.

Give us physical switches and buttons every time, like the ES. Yes, the Lexus also has them replicated within the central display, but the point is, the driver has a choice.

You shouldn't be shocked to learn that the Sports Luxury impresses most as a sumptuously comfortable back-seat experience.

Rear access is easy, the passengers can adjust the front seat, climate control and audio systems via handily-sited switches (meaning they're replicated thrice in some instances).

Limo luxury amenities include individually-reclinable and heated outboard seats that are downright sumptuous, blinds for all glass (electric for the rear window), a lined centre bin, face-level air vents, two USB ports, a 12V outlet, generously-sized elbow rests on the doors, overhead lighting and door pockets are also included.

This is tailored as an airport/hotel shuttle and very comfortable doing so.

No folding backrest, though, meaning the boot – though not small at 454 litres – lacks the load-through facilities now common in most other sedans, including the Camry.

Under the flat floor is a space-saver spare with the words ‘SPACE MISER MKIII’ emblazoned across it. Classy.

In summary, the ES’ interior is one of two parts – comfortable but dated up front, invitingly lush out back. Perfect for its intended station in life then.

The second-oldest Lexus nameplate after the LS flagship, Australia skipped the fifth-gen version from 2006 to 2012 altogether because it was ousted by the smaller, sportier and more-popular IS series.

However, the latter’s 2021 demise saw the situation flipped, with the ES retaking the mantle as the affordable Lexus sedan torchbearer, while also belatedly replacing the larger GS.

This all coincided more-or-less with a facelift later that year, which brought revised front-end styling, uprated safety, updated multimedia, extra kit and a beefier body, among other changes.

Plus, a (slightly) cheaper non-hybrid ES version returned, dubbed 250. Starting from $61,620 (all prices are before on-road costs), it uses the Camry’s 2.5-litre four-cylinder atmo petrol engine.

However, the 300h hybrid from about $2K more is the better seller, with its electric motor and battery pack assistance. Our test SL flagship kicks off from $78,180, and heaves with standard equipment.

On the safety front, the usual array of driver-assist tech is present, starting with Lexus’ pre-collision system that includes Autonomous Emergency Braking (AEB), blind-spot monitor, adaptive cruise control and lane-keep warning/assist. See the safety section for more.

The biggest change inside is the now-touchscreen-enabled 12.3-inch display, boasting a 360-degree view camera, Apple CarPlay, Android Auto, digital radio, a 17-speaker Mark Levinson audio system, CD player (!) and shockingly sub-par satellite navigation.

Beyond that, Sports Luxury buyers also score tri-beam LED headlights with adaptive high beams, an informative 8.0-inch driver display, a heated steering wheel, sunroof, powered heated/vented front seats (with memory setting for the driver), a wireless charger, head-up display, keyless entry/start, powered steering column (including retraction for easier access), active noise-control tech, rear privacy glass with sunshades, a powered boot lid with kick sensor, semi-aniline leather with a choice of walnut trims, tri-zone climate control, powered/reclining/heated outboard rear seats with centre armrest climate and audio controls, 18-inch alloys and performance (but not adaptive, crucially) dampers. More on that later.

All Lexus models also include an ‘Encore’ aftersales subscription program offering myriad offers and services including 'free' car rental.

Everything but the cliché sink, then, but is the 300h SL actually good value for money?

No rival can match the Lexus’ mix of sheer size, hybrid efficiency, spec generosity and aftersales support.

But around that $80K mark, the cheaper yet roomier Skoda Superb and smaller Volvo S60/V60 and VW Arteon 206TSI all feature all-wheel drive, as do the classy Audi A4/A5 quattros, while the rear-drive-biased BMW 3/4 Series, Genesis G70 and Alfa Romeo Giulia are far more focused on character and athleticism. Serious competition all.

And, as we found out, none can be mistaken for a Camry. Image is important at this level.

Hybrid CLAs combine a 1.5-litre, turbo-petrol, four-cylinder internal-combustion engine (ICE) with a 48-volt electric motor integrated into a new eight-speed dual-clutch transmission with drive going to the front wheels in the CLA180 and 200 and all four in the CLA 220 4Matic.

Mercedes-Benz quotes power and torque outputs for the hybrid’s petrol engine and electric motor individually and the powertrain is able to engage both simultaneously so there are overall output figures, as well. 

The pure-electric models are powered by an in-house developed permanently excited synchronous motor driving the rear wheels through a two-speed transmission, with a second 80kW drive unit added to the CLA350’s front axle for extra performance and all-wheel-drive traction. 

Here’s a panel to explain it all.

Doing duty in a cornucopia of Toyota products, the ES 300h’s A25A-FXS engine remains the same as the pre-facelift model, meaning it is a 2487cc (2.5-litre), double overhead cam, 16-valve Atkinson Cycle in-line four-cylinder petrol unit with variable valve timing.

In this application, it makes 131kW of power at 5700rpm and 221Nm of torque between 3600rpm and 5200rpm, and sends that through to the front wheels via an e-Continuously Variable Transmission (CVT) with a sequential shift facility offering artificially stepped 'ratios' for a more-conventional automatic transmission sensation.

A series/parallel full hybrid system, the engine is backed up by a permanent magnet synchronous electric motor, delivering 88kW and 202Nm, and is fed by a tiny 1.6kWh Nickel-metal hydride battery pack.

With only a couple of kilometres of pure-EV driving availability, and only under light throttle or when coasting along, the latter is recharged via the petrol engine as well as recaptured energy from the regenerative braking system. Combined power output is 160kW. No combined torque maximum is stated.

With an impressive power-to-weight ratio of 92kW/tonne, the 1740kg 300h needs 8.9 seconds to reach 100km/h, and maxes out at 180km/h.

To handle all that movement and mass, the steering is an electrically powered rack and pinion set-up, the front suspension consists of MacPherson-style struts and the rear suspension is made up of a multi-link arrangement.

Hybrid CLAs are fitted with a 48-volt, 1.3kWh lithium-ion battery and at urban speeds where less than 20kW is needed, can drive using electric power alone, depending on conditions at speeds up to 100km/h. 

Official combined cycle fuel consumption is quoted at 5.4L/100km for the CLA180 and 200, which equates to a theoretical range of close to 800km, rising to 5.8L/100km for the 220 4Matic for a potential range of around 740km. 

On the roughly 150km launch drive through Melbourne's suburbs and up the Yarra Valley north-east of the city we saw an average of exactly 5.8L/100km in the CLA220.

Electric CLAs are underpinned by a specific new-gen EV platform boasting an 800-volt electric architecture and housing an 58kWh LFP battery in the 200 electric and an 85kWh NMC pack in the 350.

Maximum charge capacity is 320kW for a claimed 10-80 per cent charge time of 22 minutes. 

Claimed energy use for the CLA200 electric is 14.4kWh/100km with a range of 470km while the AWD 350 4Matic sits at 14.9kWh/100km with a range of 663km.

Rated as Euro 6, the ES 300h requires a minimum brew of 95 RON premium unleaded petrol.

But that’s where the bad news stops, because over 626km of all sorts of driving in hot weather with the tri-zone climate control in full workout mode, we averaged an extremely commendable 5.6 litres per 100km. Well done, Lexus.

That’s against the official combined average of 4.8L/100km, which equates to just 109 grams per kilometre of carbon dioxide emissions. Not bad.

With the 50L tank brimmed, expect a real-world range of about 890km – or 1041km using the official average fuel consumption figure.

Either way, the 300h is mighty frugal for a 5.0-metre long and 1.8-tonne luxury machine. But cab and hire companies already knew that from their Camry hybrids, right?

The CLA220 4Matic was the only option available for the drive program, but for the record, claimed 0-100km/h acceleration times for the hybrid models step down in roughly one second increments - 8.8 seconds for the CLA180, 8.0sec for the 200 and 7.1sec for the 220 4Matic.

Switch to pure-electric power and the CLA200 electric hits the same speed in 7.5 seconds, while the 350 4Matic electric smashes the five second barrier at a properly quick 4.9sec.

Mind you, the 350 4Matic electric weighs about 2.1 tonnes while the hybrids tip the scales at roughly 1.7 tonnes.

There’s plenty of performance in the 220 4Matic but power delivery is not always linear with the powertrain taking half a beat to pick up after you’ve applied some throttle. Which could be the interface between the combustion engine and the electric motor or the turbo on the engine.

The sports steering wheel is grippy and chunky in the hands, and while the steering itself is nice and accurate, road feel is modest. 

There are two settings for steering weight - Comfort and Sport. We tried both, and yes, you can feel where the car’s going but it’s not exactly an intimate connection between your hands and the front tyres on the tarmac.

Speaking of which, standard rubber on the CLA220 is 225/40 Bridgestone Turanza 6 on 19-inch rims and despite those relatively large wheels the car copes well with bumps and thumps and the coarse-chip surface of rural B-roads.  

Suspension consists of a newly-developed strut-based three-link set-up at the front and multi-links at the rear with all of the major components in alloy to minimise unsprung weight.

The car remains composed and balanced through corners and the sports seats in the 220 are grippy, supportive and comfortable. We spent a couple of hours straight behind the wheel without a hint of discomfort.

The CLA’s super-slippery shape manifests itself out on the highway with minimal wind noise at 100km/h and even more. The big tyres are also quiet so the cabin environment remains refined and peaceful.

Brakes on the 220 are vented discs on the front, solid rotors on the rear. And during some pretty challenging downhill twisty sections we leant on them quite heavily. Push hard and they will bite but are not overly aggressive.

The lane-keeping, driver-monitoring and other assistance features are all there, present and accounted for. But more than ticking the box, they work very well.

The media system is driven by a high-capacity unity engine which is often used in gaming and the graphics and animations are super-smooth. And the latest iteration of the Mercedes-Benz media system works nicely across the enormous screens.

All models feature a 360-degree overhead view and a reversing camera and the 11.2-metre turning circle is not small but not vast. The car is easy to manoeuvre and park.

In the right conditions, the ES 300h is a big, squishy, comfy drive. At low speeds, for instance, thanks to an airtight cabin that does a great job isolating its pampered occupants from the outside world.

You cannot hear the car on start-up because the electric motor whirrs this Lexus off the line instantly, silently and effortlessly. And aided by all the surround-view cameras, the steering is light and direct enough to make parking a breeze. Automotive Valium to soothe your weary head after a long day.

Likewise, get the ES out on a smooth motorway and that relaxed feeling remains, with the 300h being right at home as it lopes along quietly and steadily. Cocooned in sumptuous leather and walnut, the adaptive cruise control gently rolling with the ebb and flow of traffic, it’s easy to zone out in here.

Find an empty stretch of road and you might also be impressed at how instantaneous the 300h’s throttle response is, leaping into action and piling on the speed without even breaking a sweat. This thing ain't slow!

Likewise, if you must hurry through a tight set of corners, the Lexus will remain composed and in control, without skipping a beat. Even the brakes seem well tuned and nicely modulated – something that many electrified vehicles struggle to achieve. It’s all so nice and easy.

So, what’s the catch?

First of all, while hushed when pussyfooting around, the illusion of posh sophistication is shattered once the accelerator pedal is prodded down hard, with the accompanying engine noise seeming incongruous.

Perhaps it’s because we’ve been lulled into an electric peace, but once the revs are up, no amount of sound-deadening will quell the mechanical roar.

And it's that same Camry hybrid symphony you've probably heard hundreds of times before, in the back of a taxi hurrying to the airport.

Except in the Lexus, it's far-more muffled. Like you're wearing headphones. 

Then there’s the question of bonding. While the ES 300h will do what’s asked of it capably and without complaint, there is nothing to connect car with driver.

By this, we mean that the steering is remote and feels numb at all times, with little to no feedback. Enthusiasts will search for the short way home. This is the anti-Alfa Giulia - technically a rival.

Most people will not care about that, but on the Sport Luxury’s 18-inch wheel and 235/45R18 tyre package – while modest by today’s standards – the ride quality is less than ideal on anything but smooth roads.

The ES can easily cope with small-frequency surface irritations, but seems to lack sufficient suppleness dealing with larger bumps and pot holes.

There’s an underlying and often unyielding firmness that undermines this car’s luxury aspirations. We’d dial back the taut handling for more cushiness if we could. Or fit a decent set of adaptive dampers.

Plus, the Dunlop Sport Maxx tyres aren’t as quiet as we’d expect on some of our coarser bitumen surfaces.

Comfy on smooth roads, fast when you need it to be, fit enough to go exactly where you point it to without losing composure, and wonderfully economical even when driven like it’s been stolen, the 300h has much to offer from a driving point of view.

But you won’t be aching to drive it just for fun’s sake. And you’ll quickly learn which roads are less than perfect in your neck of the woods.

Tested in 2018 under a less-strict regime, the ES delivers a maximum five-star ANCAP crash-test rating result. Back then, it scored especially strongly in Adult, Child and Vulnerable Road User categories, and quite well for Safety Assist tech.

There are 10 airbags in total (offering dual frontal, side chest, side head and front-occupant knee protection). The AEB system works between 10km/h and 180km/h, while the lane-tracing, lane-keep and emergency steering assist systems are operational from 50km/h to 200km/h.

Other driver-assist tech includes rear cross-traffic alert, blind-spot monitoring, adaptive cruise control with full stop/go and road-sign recognition and 'Intersection Assist' with 'Turning Assist'. The latter warns and brakes the car if the driver attempts to turn into oncoming traffic.

These are backed up by adaptive LED headlights with auto high beams, 360-degree view cameras, tyre pressure monitors and 'Lexus Connected Services' that can notify emergency services in an accident and track a stolen ES. An alarm with intrusion sensor is also fitted.

You’ll also find anti-lock brakes with brake-assist and electronic brake-force distribution, stability and traction control systems, three rear-seat child-seat tether anchorages and two ISOFIX latches, fitted to the outboard positions of the back bench.

The CLA is covered by Mercedes-Benz Australia’s five-year/unlimited km warranty with roadside assistance included. On top of that, there’s an eight-year/160,000km warranty on the drive battery in electric models.

That general warranty is in line with Audi, BMW and other premium players, but it’s worth noting an increasing number of brands in the mainstream market are stepping up to longer seven, eight and even 10-year cover.

Hybrid and electric variants have the same 12-month, 25,000km recommended service interval with a five-year schedule for the hybrids equating to an average of $1342 per workshop visit over that period. Reduced mechanical complexity in the EV models lowers that number to $859. But neither is especially cheap in the context of class competitors.

Here is where Lexus really excels nowadays.

Since the beginning of 2021, it caught up with most other manufacturers by offering a five-year, unlimited kilometre warranty with roadside assistance – up from four-years and 100,000km previously. Free towing and loan vehicles are provided for that period, too.

Service intervals are at 12 months or 15,000km, whichever comes first.

The ES offers three years and 45,000km of capped-price servicing, with each one costing $495 – as well as a free loan vehicle and car wash.

Plus, there’s also Lexus’ ‘Encore’ aftersales subscription program offering myriad offers and services.
