Summary
Infiniti Q50
The Infiniti Q50 Red Sport sedan really wants you to love it, and this latest version is doing its best to impress the heck out of you with its looks and features.
So much so that you'll take it home... and live with it, forever. And then there's that engine – armed with a formidable twin-turbo petrol V6, the Q50 Red Sport's outpowers all its rivals.
But then there's the BMW 340i which is not that much more expensive... and it's a BMW. And what about the Lexus IS 350? That's more like the Infiniti, but also more popular.
Oh, and don't forget that we when first met the Q50 Red Sport last year we didn't exactly get off on the right foot. The engine's formidable grunt seemed too much for the car to handle. Then there was the jiggly ride, and the steering wasn't great either unless you were in Sport + mode. It's all coming back now...
Perhaps the Q50 Red Sport had changed. This is the new one, and Infiniti had assured us it's a different car now.
Do we give it another chance? Of course, and we do, in a quick 48-hour test. So, has it changed? Is it better? Would we live with it forever?

Lexus IS
One question frequently discussed in the skunkworks of the CarsGuide office is: What exactly does Lexus stand for?
When the brand debuted its original export-market IS sedan in 1999 the messaging was more or less clear: Toyota’s premium sub-brand was here to be a Japanese BMW.
The brand even employed Nobuaki Katayama – chief engineer on the iconic Corolla AE86 program – to again take the reins of its small rear-wheel drive sedan program.
As the years went on though, Lexus changed. Fundamentally geared toward the US market, the second-generation (wild IS F aside) became a bit more sedate and softer around the edges, while the third generation strayed even further from the sedan’s performance-inspired roots, leaning into a plush interior, hybrid drive, and even CVT transmissions.
This brings us to today’s Lexus IS. Essentially a heavy facelift of the third generation (which arrived back in 2013), the brand has “reimagined” its core sedan with a tweaked design and updated technology for 2021.
Is it enough to keep it relevant against its ever-present European rivals and the newly arrived threat from Hyundai’s Genesis G70? I took a signature IS300h hybrid for a week to find out.

Verdict
Infiniti Q507.5/10
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.

Lexus IS7.6/10
Smooth, cosy, quiet, the IS looks and feels better than ever, but without a doubt this hybrid version is a car best suited to cruising the dense metropolis of Chiba at midnight more than it is carving up a bunch of S-bends in the Australian countryside on the weekend.
While that might still limit its appeal for fans of German sports luxury sedans and place it further from the original IS’s ambitions, it does offer an intriguing efficiency and luxury focused alternative, without the compromises brought by rivals with more sporting intent. In a way then, the IS 300h perhaps inadvertently best embodies what Lexus is as a brand.
Design
Infiniti Q507/10
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.
Lexus IS
Look closely and quite a lot has changed. This is really a story of doing a facelift right. Lexus has kept all the great-looking bits of the car that launched in 2013, like its striking side profile and angular accents, while dumping most of its least popular elements like the spidery front light-clusters and busy front splitter, in favour of something more refined and conservative.
It even adds some new flair in the rear three-quarter, with dramatic LED light-clusters working their way into a trendy highlight strip across the boot lid.
These changes all add up for a much tougher, sportier, and nuanced design compared to the outgoing car. One that manages to make an eight-year old design look as contemporary as ever.
I even liked our test car in its plain black shade, although I'm less sure about those conservative-to-a-fault, almost Camry-esque alloy wheels.
On the inside, sadly not a whole lot has changed. The busy design looked dated when this generation of IS launched in 2013, and it still looks dated now.
The visual assault of buttons, toggles, displays, textures, and trims is a lot to take in, and makes the cabin feel smaller than it is.
It probably didn’t help the sensory overload of this car’s interior as I hopped out of the stripped-back interior in the Tesla Model 3 I had the week before.
My less-than-impressed brother, a student of design, described the IS’s interior best when he told me “It’s a bit maximalist, don’t you think?”
If nothing else, at least Lexus hasn’t blatantly imitated anyone else when it comes to its interior, but the brand remains firm on dorky design items like the laptop touchpad, redundant drive-select dial, and odd vacant panels under the climate unit which do it no favours.
A welcome upgrade for the 2021 model year is the new media screen, a highlight piece perched atop the dash. It’s bright, has excellent contrast, and doesn’t seem to fall victim to glare.
The Apple CarPlay support I used was seamless and sharp and made the most of the available real-estate in its widescreen layout.
I somehow didn’t mind that the instrument cluster in this base car is analog. It almost suits the IS’s character better than a digital set-up would. Also offered is a small information display between the dials which I used for monitoring the hybrid drive.
A final note on the IS’s design. The fit and finish is quality, inside and out. It leaves you with an impression that this is an immaculately built vehicle, one that should be a must for all luxury cars, and always a strong point for Lexus.
Practicality
Infiniti Q508/10
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.
Lexus IS
Well, the IS is a sedan, so it doesn’t quite have that high-riding appeal of an SUV, and for this update it has even leaned further into its low-slung proportions with a roofline that descends a further 15mm and a boot lid which is 31mm lower overall.
As with the previous car, the interior is quite closed-in thanks to that busy dash design and large centre console. Rather than feeling claustrophobic though, it is best described as cosy, with lots of plush finishes throughout the doors and centre stack befitting a luxury nameplate.
Adjustability is great for the front two occupants and there are two large bottle holders between the seats, a large but shallow console box under the armrest, bottle holders with adjoining bins in the doors, and a smallish glove box.
That’s about where storage ends though, with no extra trays or bins in front of the oddly placed shifter, just an awkwardly finished plastic panel where it feels like a little tray or storage cutaway should be.
The touchpad for operating the media screen joins an unnecessary drive-select cluster in eating up centre console space where there could be more storage.
The rear seat is quite limited on space despite being lavishly trimmed. I fit behind my own (182cm/6'0") driving position with little knee or headroom to spare.
Again, it’s cosy and very comfortable, but if you're taller or wider than me you may run into issues.
The centre rear seat is all but useless for adults, with the IS’s rear-drive architecture necessitating a huge transmission tunnel that almost comes as high as the seat base itself.
Storage is limited to pockets on the back of the front seats, small bins in the doors that double as handholds, and a drop-down armrest with two bottle holders.
There are no power outlets for rear passengers, but there are dual adjustable air vents.
Boot space is 450L which is a little small for the class. It’s impressive the hybrid only managed to lose 30 litres compared to petrol-only IS variants, though, so best to count your blessings.
The largest CarsGuide travel case easily fit in the wide but short available space.
Price and features
Infiniti Q508/10
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.
Lexus IS
To be precise the variant we’re looking at here is the IS 300h Luxury. It’s the base IS trim with the hybrid powertrain and it wears a before on-road costs (MSRP) of $64,500.
Base car or not, the new IS is very well specified. Now standard are 18-inch alloys (up from 17s), full LED headlight clusters, eight-way power adjustable front seats, dual-zone climate control, 10-speaker audio system, and importantly a brilliant new 10.3-inch multimedia screen with widescreen Apple CarPlay, Android Auto, built-in navigation, and DAB+ digital radio support.
Keyless entry and push-start ignition also continue to be offered, as well as a leather-look interior trim which in our car was in a rather contrasting 'Ochre' colour option.
Our IS 300h was also fitted with the creatively named ‘Enhancement Pack 1’ which adds an openable moonroof for $2000. The significantly more expensive ‘Enhancement Pack 2’ ($5500) adds the moonroof alongside 19-inch alloys, upgraded LED headlights, interior ornamentation, scuff plates, a panoramic reversing camera, 17-speaker premium audio, ‘leather-accented’ interior trim, ventilated front seats, and an electric rear sunshade.
These packs are seemingly largely unnecessary but are also very cheap for a brand at the premium end of the market.
Lexus has made pretty much all of its high-end active safety equipment standard on this base ‘Luxury’ for 2021, alongside some previously unavailable tech which we’ll take a look at in the safety section of this review.
At this price the Lexus IS 300h goes into battle against the Mercedes-Benz C 200 ($66,900), BMW 320i ($70,900), Audi A4 35 TFSI ($55,900), and the ever-looming threat of Hyundai’s Genesis, which offers its similarly-sized G70 in base form at $59,300.
Some of these base-spec rivals are cheaper, some are more expensive, but did you notice none of them are hybrids?
Access to Toyota’s affordable and popular hybrid drive is a real point of difference for the Lexus brand, and we expect it’s a key drawcard for the loyal customer base. More on that later.
Under the bonnet
Infiniti Q508/10
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.
Lexus IS
The IS 300h does stand out from the luxury sedan crowd by offering a hybrid drivetrain at a reasonable price. Some rivals offer plug-in options further up the price scale cementing them as a niche option, but the beauty of this Lexus is its very mild $3000 price jump over the base petrol car.
The base car’s 2.0-litre turbo is dumped in favour of a 2.5-litre non-turbo Atkinson-cycle four-cylinder hybrid set-up similar to the one proving popular in the Toyota Camry and RAV4.
The petrol engine produces 133kW/221Nm on its own, and the electric motor produces 105kW/300Nm. Toyota says the “combined system output” of this is 164kW.
Either way, that's less than the base 2.0 turbo. The 300h also swaps out an eight-speed torque converter automatic in favour of a continuously variable transmission. Rare in a rear-wheel drive car.
Efficiency
Infiniti Q507/10
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.
Lexus IS
As you might hope this hybrid IS has an astoundingly low official/combined fuel consumption rating of 5.1L/100km.
I was pleased to find that after a week of mainly urban driving conditions, our IS was returning a figure of 6.9L/100km. Not bad at all, especially for a class where fuel consumption can get a little out of hand with turbocharged engines or V6s.
Of course, using the hybrid system to your advantage over the long term will get this number much lower, as I discovered on my long-term test of the Toyota Corolla hybrid which essentially uses a smaller version of the same system.
Certainly, if fuel consumption is a high concern, you’re better off with this car than the top-spec V6 (IS 350) which will easily see consumption enter double digits.
Lexus recommends a minimum RON rating of 95 for the IS 300h, and the fuel tank is 66 litres regardless of variant, giving the hybrid an impressive theoretical range of around 1000km.
Driving
Infiniti Q507/10
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.
Lexus IS
There is no doubt the IS 300h is capable. You can feel it through the car’s solid rear-drive underpinnings, silky smooth steering, and reactive chassis.
What this car doesn’t offer is excitement in quite the same sense as many of its rivals. That’s down to this hybrid’s drivetrain. It just doesn’t have that powerful follow-through in the same way turbocharged BMWs or Audis or Mercedes do.
If it’s that 'sports luxury' experience you’re seeking better off looking to the base 2.0-litre turbo or the V6 and their eight-speed automatics.
The 300h does offer something a bit different. The gentle refined efficiency of Toyota’s signature hybrid system in a luxury rear-drive package that’s smaller than this car’s ES bigger brother.
While it may feel capable thanks to the lighter suspension components and altered track that the brand has committed to for this update, the hybrid drive matches this car’s softer character brought about by its gentle suspension tune and light steering.
This is an easy car to drive around a city, it filters out bumps nicely, while offering near silence in the cabin and breezy steering for every day scenarios like manoeuvring in tight parking lots.
The CVT auto and instantaneous torque available from the electric motor make it best at traffic speeds, being both reactive and predictable, with silent acceleration when inching forward at the lights or cruising along at 50km/h.
As you might expect though, the wheezy Atkinson cycle engine and CVT conspire for a noisy and less than engaging experience under heavy acceleration.
It’s not as though you’re rewarded with particular vigour either, with this combination being a bit sluggish when a lot is asked of it.
It loses its reactivity and refinement at higher speeds or in the corners on country roads as the transmission elastically tries to keep up with the demands of the driver.
Still, few luxury sedans are quite as purpose-built for the toils of a city, and if you want to get drawn into this car’s hybrid drive antics, it’s easy to make a game out of saving fuel by trying to rely on its low-speed electric motor capability.
Really then, it leans into its urban luxury appeal. A luxury sedan for the streets of Tokyo. An ideal car in this class for the urban environment.
If you don’t care for the thrill of a turbocharger or frequently seek to explore the twists of your nearest B-road, you could do worse than the comfort and ambiance the 300h offers.
Safety
Infiniti Q508/10
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.
Lexus IS
A full active safety suite is now standard across the IS range, including freeway-speed auto emergency braking with pedestrian detection (works during the day and at night) and cyclist detection (works during the day only), and a new intersection braking feature, lane keep assist with lane departure warning, blind spot monitoring, rear cross traffic alert with reverse auto braking, traffic sign recognition, adaptive cruise control, and auto high-beam assist.
There is also an auto SOS function, as recently added to the Toyota Yaris Cross, which automatically triggers if an airbag is deployed. On the topic of airbags, every IS has a thorough suite of 10 (dual front, dual side, quad head, dual front knee).
This all adds up with the standard array of stability, brake, and traction controls for a maximum five-star ANCAP safety rating, although the IS was last assessed way back in 2016.
The IS is built in Japan.
Ownership
Infiniti Q507/10
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.
Lexus IS
Lexus gets slightly ahead of the luxury pack with an extra year of warranty. While BMW and Audi still sit on three, Lexus offers four, but it is limited to 100,000km and is still outdone by Mercedes-Benz and Korean newcomer, Genesis, offering five-year/unlimited kilometre promises.
The IS has capped price servicing fixed at $495 for the first three years of ownership with roadside assist, and the brand will even pick up and drop off your car, or offer a free loan car during every 12 month or 15,000km service.
It’s worth noting that German rivals offer pre-paid service packages out to five years, and Genesis is trying to make a splash with free servicing.
Lexus does offer a luxury ownership program dubbed ‘Encore’ which includes invites to experiences and certain partnerships with restaurants and the like to keep potential owners enticed.
