Lexus ES vs Infiniti Q50

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 Q50 Red Sport is a premium sedan that's great value, with a cracker of an engine. While Infiniti has improved the ride and steering, it still feels to me that the engine is too powerful for the wheels and chassis to handle. But if you're looking for something of an untamed beast, this car could be for you. Just don't say we didn't warn you.

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 Q50 Red Sport looks cranky from front on, which I like in a car. Yes, the grille is simplistic and gaping, the nose is a bit bulbous, and sure, side on the car looks like a Lexus IS 350, but those rear haunches and the aggro body kit with its front splitter and boot lid spoiler make for an impressive looking four-door sedan.

The update brought restyled front and rear bumpers, those red brake calipers and the dark chrome 20-inch rims and new LED tail-lights.

Inside, the cabin is an asymmetrical paradise (or hell, if you're a bit OCD like me) full of sweeping lines, angles, as well as different textures and materials.

The red stitched quilted leather seats are an addition that came with the update, so is the new steering wheel and the ambient lighting.

The 'Sunstone Red' colour of our test car is also a new hue which looks a bit like Mazda's Soul Red. If red is not you, there are other colours – hope you like blue or white or black or grey because there's 'Iridium Blue', 'Midnight Black', 'Liquid Platinum', 'Graphite Shadow', 'Black Obsidian', 'Majestic White' and 'Pure White'.

The Q50 has similar dimensions to the IS 350: both are 1430mm tall, the Infiniti is 10mm wider at 1820mm,  120mm longer at 4800mm, and has a wheelbase that's 50mm longer at 2850mm.

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 Q50 Red Sport is a five-seat four-door sedan and is vastly more practical than its two-door Q60 Red Sport sister, in that I can actually sit in the back seat. The Q60's coupe styling looks amazing, but the sloping roofline means headroom is so severely limited that it reduces the rear seats to a place to throw your jacket.

True, I'm tall at 191cm, but in the Q50 Red Sport I can sit behind my driving position with legroom to spare and more than enough headroom.

Boot space is good at 500 litres, which is 20 litres more than the luggage capacity of the IS 350.

Storage throughout the cabin is good with two cup holders in the rear centre fold-down armrest, two more up front and bottle holders in all doors. A large centre console storage bin and another big storage area in front of the shifter are great for keeping junk under control and your valuables covered.

Maybe sit down for this next bit. The Q50 Red Sport lists for $79,900. Are you okay? Do you want a moment? Remember, though that only seems like a lot because it's not a Benz or a BMW. Truth is the value is pretty good – better than a German car of the equivalent size and grunt.

Look at the standard features list: 8.0-inch and 7.0-inch stacked touchscreens, the 16-speaker Bose 'Performance Series' stereo system, digital radio, road noise cancellation, sat nav, 360-degree camera, leather seats, power adjustable from sports seats, dual-zone climate control, proximity key, sunroof, auto wipers and adaptive LED headlights.

The 2017 update brought new standard features to the Red Sport including, red stitching on the seats and dash, quilted leather seats, new 19-inch alloy wheels and red brake calipers.

Don't forget that the bang-for-buck factor is strong with the Red Sport, too. In that nose is a twin-turbo V6 that makes almost as much grunt as the BMW M3 for about $100K less. Even the 340i, which Infiniti says is a Red Sport rival, is $10K more. Truth is though, the Lexus IS 350 is the real rival to the Q50 Red Sport.

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.

Inside the Q50 Red Sport's nose is a 3.0-litre twin-turbo V6 petrol engine and it is a beautiful thing. To me this car is piece of technologically sophisticated jewellery that cradles a precious gem that pumps out 298kW/475Nm.

But I have my concerns... you can read about those in the driving section.

Shifting gears is a seven-speed automatic which delivers drive to the rear wheels.

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?

Infiniti says the V6 petrol engine in the Q50 Red Sport should use 9.3L/100km if you're using it on a mix of highways, urban streets and country roads. We only had the Q60 Red Sport for 48 hours and after a couple of days of Sydney city commutes and a trip to the Royal National Park our trip computer was reporting 11.1L/100km.

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.

Perhaps the biggest complaint we had about the previous Q50 Red Sport, which launched in 2016, was that it felt as though the chassis wasn't up to the amount of grunt running through it, and those rear wheels struggled to transfer the oomph to the road without losing traction.

We experienced the same issue again in this new car. I was breaking traction, not just in 'Sport+' and 'Sport' modes, but in 'Standard' and 'Eco', too. That was happening without pushing it hard and with all electronic traction and stability aids on.

If I was 18 I'd declare to the world I'd found my dream car - something that always wants to 'light 'em up' given half a chance. But like that one mate who always gets into trouble on a night out it's only funny when you're young.

A truly great performance car is planted, balanced and able to deliver the grunt to the road effectively. The Nissan R35 GT-R is the perfect example – a brilliant piece of machinery, a weapon of a performance car and with a chassis matched perfectly to its engine.

And that could be the issue with Q50 Red Sport - that engine feels overpowered for the chassis, and wheel and tyre package.

We also felt the previous Q50 Red Sport's ride, with its constantly adapting 'Dynamic Digital Suspension', was overly busy. Infiniti says it has developed the suspension system further and it does feel as though the ride is more comfortable and composed.

Steering was another area that we weren't overly impressed with when we drove the previous car. Infiniti's 'Direct Adaptive Steering' (DAS) system is super sophisticated and was the first in the world not to have any mechanical connection between the steering wheel and the wheels – it's all electronic.

The new Q50 Red Sport uses the upgraded 'DAS 2' and while it feels better than before, it's only in Sport+ mode that it seems most natural and accurate.

The Q50 was given the maximum five-star ANCAP rating in 2014 and the amount of advanced safety equipment which comes standard on the Red Sport is impressive. There's AEB, that works forwards and when you're reversing, forward collision and blind spot warning, lane keeping assistance and moving object detection.

There are two ISOFIX points and two top tether anchor points in the back row, for child seats.

The Q60 Red Sport doesn't come with a spare tyre because the 245/40 R19 tyres are run flats, which means even after a puncture you should be able to keep driving for about 80km. Not ideal in Australia where distances are seriously vast.

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.

The Q50 Red Sport is covered by Infiniti's four year/unlimited kilometre warranty with servicing recommended every 12 months or 15,000km.

Infiniti has a scheduled servicing program which will cost $1283 (in total) for three years.
