Lexus ES300H vs Toyota Prius

What's the difference?

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.

The Prius can rest its weary head. The Age of the Hybrid has begun. Even though this iconic eco car might have lost its ultimate purpose to more mainstream models in the last few years, it’s still the best execution of Toyota’s hybrid tech on the market and if you can look past its divisive-as-ever looks, it’s comfortable and practical, too.

The brand’s Australian division promises the Prius will stick around in one form or another, so we’re keen to see what its next iteration will look like. Plug-in? Fully electric? Time will tell.

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.

The Prius is the very visage of economic motoring. Derided by big-engine lovers, and adored by the eco-crowd, the fact that the Prius’s wedge-shaped frame is more about function than form tells you everything you need to know about this car.

It blends with Toyota’s latest design language, the face and bodywork containing some subtle nods to other models that would launch after it, like the Corolla, Camry, and C-HR.

What always surprises me about even this top-spec Prius is its dorky ride height. For a car with such a low drag coefficient, it sits so far off the ground! The 17-inch wheels look almost out of alignment with the body in those wheelarches.

Round the back, the Prius’s integrated spoiler and glasshouse bodywork are as divisive as ever, with more extreme pointed light fittings leaning into the effect created by its boxy, rear three-quarter view and mirroring the shape of the LED headlights at the front.

Of course, this car is less about being looked at as it is about its drag coefficient of 0.24 Cd, which is one of the lowest on any production car.

Inside, things again prove divisive, with a minimalist dash, a swoopy gloss highlight piece that frames the central vents and multimedia screen, and an odd, centrally mounted dash cluster, which is a usability faux pas.

In the case of the I-Tech at least there’s a holographic display which can put up useful information to help prevent your eyes from drifting too far from the road. Still, I can’t help but feel like this whole interior ethos is futuristic for the sake of being futuristic, with a little less thought given to how practical it is, compared to the brand’s other models.

The leather-appointed trim across the wheel and soft plastics in the door and dash-topper are appreciated, and there’s attention to detail in the little ‘Prius’ logos on the vents. However, I found the dull multimedia screen to be susceptible to glare during the day, and the big integrated panel in which it sits is made from a tinny gloss plastic, which will easily to get covered in fingerprints and scratches.

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.

If nothing else, all of the Prius’s edgy design gives it plentiful interior space. Toyota granted this generation of Prius a low seating position and tall roof, which combine with the distant dash elements to make for a spacious cockpit for the front two occupants.

The seat design in the top-spec I-Tech is also cushy, reminiscent of the seats in high-spec Camrys, and I had absolutely no trouble finding a comfortable driving position. If there’s one thing to be said for the annoying, centrally mounted instruments, it’s that you don’t need to consider the position of the wheel interfering with their visibility.

The Prius’s total glasshouse grants superb visibility out the front and sides, with large wing-mirrors, too. The only downside is that integrated spoiler at the back, which makes for a distracting view out the rear mirror that I’m sure any owner will quickly become accustomed to.

Soft trims across the doors and centre console, even in the back seat, make the Prius cabin a comfortable place to be, too.

Ergonomics have not been forgotten, with the multimedia screen and climate unit having useful and easy-to-reach physical dials and toggles for all the key functions. Even changing gear is a breeze in the Prius, with its odd little rosebud-shaped shifter simply a flick of the wrist from where your arm sits.

I do wish Toyota had made better use of the large area under the climate unit, however. The front part of the centre console is exclusively for the wireless-charging bay alone, and the rest of the space is constructed from a smoothly contoured gloss-finish plastic panel. It has looks to match the Prius aesthetic, but it’s no good for storing anything other than a single phone. It would have been better to make a large bay here with a rubberised finish.

Thanks to the lack of a physical handbrake in the centre or any other buttons or functions, there are two large bottle holders with variable edges.

A huge centre-console box and large door bins round out the Prius’s front-seat storage options.

Room in the rear seat is excellent, my 182cm tall frame had stellar amounts of space for my legs and head, as the roofline continues through to that raised rear spoiler. The comfy seat trim continues, although the padding in the base is notably not as good as it is in the front.

There are some useful pockets on the backs of the front seats and a drop-down armrest with cupholders for rear passengers, too.

Finally, the awkward rear of the Prius makes for a fantastic boot capacity, one advantage this car still holds over its hybrid Toyota stablemates. Capacity for the I-Tech is a mid-size-SUV rivalling 502-litres (VDA), which easily consumed our CarsGuide test luggage set and is even bigger than the base Prius, at the cost of the space-saver spare wheel. The I-Tech only has a repair kit to go with its larger alloys.

This Toyota Prius in top-spec I-Tech form costs a whopping $45,825 before on-road costs, which is a tall order, especially given the fact that the technical advantage this car once had to help justify its price-tag has been lost to the rest of Toyota’s range.

An equivalent Corolla hybrid, even in top ZR trim, can be had from just $34,695, and even the much larger Camry in its highest hybrid SL trim is more affordable, at a suddenly cheap-looking $42,790. All three Toyotas are sourced from Japan.

Not a good start in the value battle, then, especially since those other Toyotas are not just hybrids, but great cars in their respective segments.

The Prius I-Tech’s most direct rival is the similarly shaped and sized Hyundai Ioniq Premium, which can be yours from $40,390 with competitive equipment. Hyundai is not only hunting Toyota with this car, but flexing its deep pockets by selling the Ioniq in Australia as not just a hybrid, but a PHEV and a full EV, too.

Thankfully, the I-Tech comes with some decent gear, sporting 17-inch alloy wheels, a 7.0-inch multimedia touchscreen with Apple CarPlay and Android Auto connectivity, digital radio, a 4.2-inch digital information display, a holographic head-up display, full LED lighting with auto-levelling, leather-appointed seat trim, auto dimming rear vision mirror, wireless phone charging, 10-speaker audio, and improved interior trims over the base car.

The I-Tech also scores a larger boot capacity and an improved safety suite compared to the base Prius. More on that in later sections of this review.

Is the Prius “good value” then? It's still a no, as all of this equipment can be had in bigger, more mainstream Toyota models, and far more affordable rivals. It’s a shame Toyota hasn’t brought the Prius’s cost down in the five years since this generation launched, because in today’s market it makes less sense than ever.

That said, there is a certain niche audience for this car. One that will always love its little innovations, like the fact that it has one of the lowest drag coefficients on the market, its stellar fuel-consumption number, and its claimed 40 per cent thermal efficiency.

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.

It wouldn’t be a Prius without Toyota’s signature hybrid synergy drive technology. In this most original case it consists of a 1.8-litre four-cylinder petrol engine, which uses the more thermally efficient but less powerful Atkinson combustion cycle, producing 72kW/142Nm, paired to a set of electric motors on the front axle, which can produce up to 53kW/163Nm.

Combined system output is rated by Toyota at 90kW, driving the front wheels only via a continuously variable automatic transmission (CVT). This system is the same one now also employed in the C-HR and Corolla hybrid grades.

The Prius’s electric motors source their power from an older design nickel-metal hydride battery (instead of the more modern lithium-ion setup) located under the boot floor.

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 Prius’ sandpapered hybrid drive, low drag number, weight reductions, and low-rolling-resistance tyres add up for a stellar official/combined fuel-consumption figure of just 3.4L/100km. While its signature hybrid tech might be available on other Toyota’s, it’s here where the Prius still shines, undercutting the others by almost a whole litre every 100km.

But can it live up to that promise in the real world? Over my week of what I would consider to be reasonable ‘combined’ driving conditions; with plenty of traffic, freeways, and suburban driving, the Prius returned a stellar figure of just 4.0L/100km. This is not just one of the lowest figures I have ever achieved on a test car, it is even lower than the Corolla Hybrid that I tested over a three-month period. I couldn’t get that car below 4.9L/100km, despite by best attempts.

For a true rival comparison, my week-long test of the Ioniq hybrid in 2019 had the Korean managing a fuel number of 4.6L/100km.

You need not worry about kWh energy consumption for the Prius, as its hybrid system’s software manages the state of battery charge on the fly. It will simply run the engine to charge the battery if levels drop too low, although it always feels good to make the most of the motor’s regenerative braking to keep the battery topped up.

It’s clear that the Prius is still the king of hybrid, then. At least for the time being. All Prius models have 43-litre fuel capacities and are able to consume base-grade 91RON unleaded.

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.

The Prius was responsible for popularising Toyota’s Hybrid Synergy Drive, and fittingly, it still feels like the best execution of the technology on the market. That instantly available torque from the electric motor is sleek, quiet, and easy. It feels as though the Prius can make more extended use of purely electric drive than not only its rivals, but all other Toyota and Lexus hybrid products.

Despite its awkward exterior looks, the ride and handling of the Prius are excellent, thanks to its robust TNGA-C underpinnings (in fact, the Prius was the car to debut this platform for Toyota). It tilts into corners nicely, despite a frumpy ride height, and deals with bumps in its stride. This is a comfortable car, and the Lexus influence here is undeniable. The steering characteristics are also smooth and responsive. I wouldn’t go so far as to say the Prius is fun to drive, but it is certainly comfortable and compliant.

What the Prius lacks is the lower, firmer, and more aggressive ride and handling characteristics of its Hyundai Ioniq rival, perhaps a telling insight into the trajectory of each brand.

These characteristics add up to an around-town driving experience that really is a breeze. It’s quiet in the cabin and at times genuinely hard to tell whether the car is using its electric motors or the engine. When it comes to bursts of acceleration, the Prius might surprise you. Using both the motor and engine in tandem, I found that the Prius can sprint from the line with an alarming urgency, more so than its Corolla sibling. With the same tech behind the accelerator pedal, it’s hard to imagine why.

Once the electric motor has reached its strictly defined limit, though, the engine breaks in with a vengeance, and this car does have an anaemic follow-through when the electric components fall to the wayside. As in other applications of this drivetrain, the 1.8-litre Atkinson-cycle petrol engine can be thrashy and noisy when a lot is asked of it.

Of course, driving in such a sporty manner is hardly the point of the Prius, and where it really excels is in that day-to-day traffic grind, where the hybrid system works largely in the background to maximise the time spent with the engine off. The best part? While you can really fall into the hybrid system’s addictive fuel-saving displays, which really encourage hypermiling, this is a set-and-forget system. You can drive the Prius like any other car, and it will be trim on fuel consumption anyway. It’s not like I was trying awfully hard to attain my weekly figure of 4.0L/100km, so I’m sure it can do better over the long term.

The Prius wears a maximum five-star ANCAP safety rating to the 2016 standards, although even in today’s market it has a great active-safety suite.

Standard modern active features on all Prius models include freeway-speed auto emergency braking with pedestrian and daytime cyclist detection, lane-keep assist with lane-departure warning, adaptive cruise control, traffic-sign recognition, and auto-high beams. Our top-spec I-Tech adds blind-spot monitoring and rear cross traffic alert, for an overall excellent suite.

All Prius varaints are also equipped with seven airbags consisting of the standard front, side, and head, as well as a driver’s knee airbag, and the standard array of electronic stability and brake controls are also present.

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.

Toyota’s range-wide warranty currently stands at five years or unlimited kilometres, which is really the accepted industry standard and matches its key Ioniq rival.

Annoyingly, however, the Prius needs to adhere to six-monthly or 10,000km service intervals. Said intervals are capped to $165 per visit for the first six visits under Toyota’s “service advantage” program, after which time you fall back to Toyota genuine servicing with significant price hikes to $221.97, and $425.47 for the next two services covering four years or 80,000km.

A year of roadside assist is included, after which time you will need to subscribe to Toyota’s program, from $89 a year.

While Toyota’s offering is on par with many, it’s hardly the cheapest or most comprehensive we’ve seen.
