Lexus IS350 vs Subaru WRX

What's the difference?

The new-look Lexus IS takes several steps forward over its predecessor - it’s safer, smarter, sharper to look at and still pretty well priced and equipped.

It is feeling its age inside, and the competition has moved on in terms of engines and EV tech. But even so, if I was buying a 2021 Lexus IS, it would have to be the IS350 F Sport, which is just the most fitting version of this car, though the IS300h Luxury does have plenty to like for the money, too.

Over three decades the WRX has matured into a more grown-up, refined performance package.

It’s fast with excellent dynamics, yet comfortable. Safety’s top-shelf, it’s well screwed together and the value equation stacks up. Rear seat headroom could be better and service costs are on the high side for the category. But I just love the way this car puts you in control.

You either get the Lexus look or you don’t, and I think this latest version is possibly more agreeable than the IS in years gone by.

That’s partly because the brand has finally done away with the odd spider-eyes twin-section headlights and daytime running lights - now there are more traditional headlight clusters, which look a lot more resolved than before.

The front end still features a bold ‘spindle’ grille, which gets different treatment depending on the grade, and the front, to my eye, looks better than before but still very much stuck in its ways. 

At the side you’ll notice the giveaway windowline hasn’t changed, despite the chrome trim line having broadened as part of this facelift, but you can tell the haunches have muscled up a bit, with the new IS now 30mm wider overall, and the wheel sizes are 18s or 19s, depending on the grade.

The rear accentuates that width, with an L-shaped lighting signature now spanning the entire re-sculpted boot lid, giving the IS a pretty tidy rear end design.

Overall dimensions for the IS are 4710mm long, making it 30mm longer nose to tail (on an unchanged 2800mm wheelbase), while it now spreads across 1840mm (+30mm) and is 1435mm tall (+5mm).

The exterior changes really are impressive - I think it is a more purposeful but also more pleasant looking car now than it ever has been in this current generation. 

The interior? Well, there’s not a whole lot to talk about in terms of design changes, aside from the repositioned and larger media screen - which sits 150mm closer to the driver because it’s now a touchscreen with the latest smartphone mirroring tech. Otherwise it’s a carryover affair, as you can see from the interior pictures.

For a while there in the mid- to late teens it felt like Subaru was pulling the wraps off a ‘VIZIV’-themed concept car design roughly once every five minutes.

Future-focused SUVs, crossovers and wagons, as well as 2017’s Performance Concept, a muscular four-door that clearly had an influence on the look and feel of this car.

From its sinister headlights and all-business hood scoop to the pumped-up flared guards with black 18-inch alloys filling them, the WRX’s intent is clear.

And at the back the professional-grade theme continues with dual twin exhaust tips, boot lid lip spoiler and what looks like a multi-vane diffuser that’s actually more cosmetic than functional.

That said, a low-key technical design feature is the integration of air outlets on the trailing edges of the front wheel arch flares and the outer edges of the rear bumper.

This is to release air pressure from the wheel arches, forming external vortices to minimise body sway and drift caused by wind turbulence.

Inside, the cabin treatment is a fairly busy mix of sharpish angles and shallow curves, the dash dominated by an 11.6-inch, portrait-oriented multimedia screen with a separate instrument pod for the driver next to it.

The colour palette is mid-grey to black with dark metallic highlights here and there, with alloy covers on all three pedals as well as patches of faux carbon on the doors and steering wheel.

Sports front seats look and feel good and the overall standard of fit and finish is high.

The interior design of the IS, as mentioned, hasn’t changed dramatically, and it is starting to feel old compared to some of its contemporaries.

It’s still a nice place to be, with comfortable front seats with electric adjustment and heating across all grades, and cooling on many variants, too. 

The new 10.3-inch touchscreen media system is a nice unit, and means you can essentially do away with the silly trackpad system that still resides near the gear selector, so you may still end up bumping it accidentally. And the fact the IS now has Apple CarPlay and Android Auto (though neither are wirelessly connectable) does further its appeal on the multimedia front, as does the standard 10-speaker Pioneer stereo - though the 17-speaker Mark Levinson unit is an absolute blinder!

The centre stack below the media screen retains a CD player, and still has the electromagnetic temperature adjustment sliders as well. That part of the design is dating it just as much as the transmission tunnel console area, which looks a bit out of touch by modern standards, though still incorporates a pair of cup holders and a reasonably large centre console bin with soft armrest padding.

The front doors feature trenches with bottle holders as well, while in the rear doors there is still no drink storage - a carryover annoyance from the pre-facelift model. However, the middle seat in the back doubles as an armrest with pop-out cupholders, and there are rear air vents too.

Speaking of that middle seat, you wouldn’t want to sit in it for long, as it has a raised base and uncomfortable backrest, plus there’s a huge transmission tunnel intrusion eating into leg and foot space.

Outboard passengers also miss out on toe room, which - for my size 12s - is an issue. And it’s hardly the roomiest second row in this class for knee room and headroom, as my 182cm frame was a touch squished behind my own driving position.

Children will be better catered for in the back, and there are two ISOFIX anchorages and three top-tether attachment points for baby seats.

The boot capacity varies on the model you buy. Choose an IS300 or IS350 and you score 480 litres (VDA) of cargo capacity, while the IS300h has a battery pack that robs it of some boot space, with 450L available. 

At just under 4.7m long, a little over 1.8m wide and close to 1.5m tall, with a roughly 2.7m wheelbase the WRX stands as a ‘big’ small sedan.

At 183cm I’ve got more than enough breathing room in the front, the away slope of the dash enhancing the feeling of space.

For storage, there’s lots, including a centre console box between the seats, two cupholders and some oddments trays in the centre console, door pockets with room for decent size bottles and a medium glove box

And in the back, sitting behind the driver’s seat set to my position, there’s good foot room, ample legroom, but sitting straight I experienced a bonce-to-roof interface in terms of headroom. No adjustable ventilation, either. Thumbs down.

Storage options include door bins with room for bottles, a single map pocket (on the back of the front passenger seat) and two cupholders in the fold down centre armrest.

Power and connectivity runs to a 12V socket in the front as well as USB-A and -C sockets for charging and/or media.

Plus two USB charge ports (again -A and -C) in the back, the latter a model year 2024 spec upgrade.

The WRX’s boot offers 411 litres of storage space, which is enough to accommodate our three-piece luggage set, but remember, the aperture isn’t as accommodating as a hatch or SUV’s. The 60/40 split-folding rear seats improve flexibility, though. 

A space-saver spare sits under the floor and braked trailer towing capacity is a handy 1200kg.

The Subaru WRX RS weighs in at $52,990, before on-road costs, and the RS Sport with CVT auto is a fraction below 55 and a half thousand dollars.

There are some tasty alternatives around that price band, including the Toyota GR Yaris ($51,390), Mazda MX-5 GT RS ($51,640) and Mini Cooper S Clubman Classic ($53,250).

But maybe the most telling competition is closer to home with the less powerful but even purer Subaru BRZ tS ‘2+2’ manual coupe undercutting its WRX RS sibling by more than four grand at $48,690, before on-road costs.

Either way, aside from the standard performance and safety tech we’ll get to shortly, this car boasts an impressive features list including dual-zone climate control air, eight-way power-adjustable and heated sports front seats, heated outboard rear seats, interior ambient lighting, synthetic suede seat trim, built-in sat-nav and an 11.6-inch portrait-oriented multimedia screen (with voice command).

There’s also 10-speaker Harman Kardon audio (with digital radio and 265mm subwoofer), wireless Android Auto and Apple CarPlay, keyless entry and start, a leather-trimmed steering wheel, adaptive cruise control, a sunroof, exterior LED lighting all around, ‘Steering Responsive Headlights’, rear privacy glass and 18-inch alloy wheels. 

Relative to its asking price and closest competitors this WRX RS delivers plenty of bang for the buck when it comes to performance and value.

The engine specs depend on the powertrain you choose. And at a glance there’s no variance between the earlier version of the IS and the 2021 facelift.

That means the IS300 model still runs a 2.0-litre turbocharged petrol motor producing 180kW of power (at 5800rpm) and 350Nm of torque (at 1650-4400rpm). It has an eight-speed automatic transmission, and like all IS models, it is rear-wheel drive (RWD/2WD) - there is no all-wheel drive (AWD/4WD) model here.

Next up the spectrum is the IS300h model, which has a 2.5-litre four-cylinder Atkinson cycle petrol motor teamed to an electric motor and nickel metal hydride battery pack. The petrol engine is good for a 133kW (at 6000rpm) and 221Nm (at 4200-5400rpm), and the electric motor produces 105kW/300Nm - but the combined total maximum power output is 164kW, and Lexus doesn’t provide a maximum torque figure. The 300h model runs a CVT automatic transmission.

The big horsepower offering here is the IS350, which runs a 3.5-litre petrol V6 engine, producing 232kW of power (at 6600rpm) and 380Nm of torque (at 4800-4900rpm). It runs an eight-speed auto.

All models have paddle-shifters, while the two non-hybrid models have seen tweaks to the transmission software that is said to “estimate driver intentions” for better enjoyment. 

The WRX RS is powered by a 2.4-litre, horizontally opposed four-cylinder, turbo-intercooled petrol engine developing 202kW and 350Nm.

Some call it ‘flat’, others a ‘boxer’, but either way it’s the Rex’s mechanical calling card delivering its distinctively raucous, pulsing engine and exhaust sound.

The all-alloy unit features direct-injection and dual variable valve timing, its relatively flat design lowering the car’s centre of gravity significantly. 

And as mentioned earlier, in this case it’s connected to a six-speed manual gearbox driving all four wheels via a centre viscous limited slip differential able to distribute drive between the front and rear axles on demand. But you can have a CVT auto if you really want one in the RS Sport. 

There’s still no diesel model, no plug-in hybrid and no full electric (EV) model - which means that while Lexus was at the forefront of electrification with its so-called “self-charging” hybrids, it is falling behind the times. You can get plug-in versions of the BMW 3 Series and Mercedes C-Class, and the Tesla Model 3 plays in this space in full-electric guise.

As for the fuel-sipping hero of this trio of powertrains, the IS300h is said to use 5.1 litres per 100 kilometres on the combined cycle fuel test. In reality, our test car’s dashboard showed 6.1L/100km across a mix of driving.

The IS300 with its turbocharged 2.0L engine is next best for fuel use, claiming 8.2L/100km. On our short launch drive of that model, we saw 9.6L/100km on the dashboard.

And the full-fat IS350 V6 petrol claims consumption of 9.5L/100km, while on test we saw 13.4L/100km.

The emissions for the three models are 191g/km (IS300), 217g/km (IS350) and 116g/km (IS300h). All three are Euro 6B compliant. 

Fuel tank capacity is 66 litres for all models, meaning your mileage range for the hybrid model could be considerably longer.

Subaru’s official combined cycle fuel-economy figure for the WRX RS is 9.9L/100km, which is moderate for a performance sedan like this. And it emits 225g/km of CO2 in the process.

Over a week covering mainly urban and suburban driving, with some enthusiastic sessions and a hint of freeway running thrown in, we recorded an average of 10.6L/100km, which isn’t outrageous.

Worth noting the minimum fuel requirement is the pricier 95 RON premium unleaded and you’ll need 63 litres of it to fill the tank which translates to a theoretical range of around 635km and roughly 595km using our real-world number.

With the engine at the front and drive to the back, it has the ingredients for a pure driver’s car, and Lexus made a bit of a big deal about the new-look IS being more focused thanks to chassis adjustments and track width improvements - and it does feel a pretty nimble and tied-down car in the twisty stuff. 

It is competent at stitching together a series of corners, and the F Sport models are particularly adept. The adaptive suspension in those models includes both anti-dive and anti-squat tech, which is designed to make the car feel solid and flat on the road - and it does, thankfully without feeling twitchy or uncomfortable, with good suspension compliance even in the most aggressive Sport S+ drive mode.

The 19-inch wheels on F Sport models are fitted with Dunlop SP Sport Maxx rubber (235/40 front, 265/35 rear) and there’s plenty of tarmac tenacity.

The grip from Luxury-spec models on 18s could be better, with those Bridgestone Turanza tyres (235/45 all around) proving not quite the most enthralling. 

Indeed, the IS300h Luxury I drove felt very different in character to the F Sport IS300 and 350 models. It was surprising how much more of a plush-focused model the Luxury grade feels, and likewise it wasn’t as impressive in dynamic driving due to the tyre grip and less-enthusiastic drive mode system. The non-adaptive suspension is a touch more jittery too, and while it’s not to the point of discomfort, you might expect better for a car on 18s.  

Across all models the steering is accurate and direct enough, with predictable response and decent feel to the driver’s hands for this electric power steering setup. The F Sport models have even further retuned steering for “an even sportier drive experience”, though I found at times it could feel a little numb for rapid changes of direction. 

As for engines, the IS350 is still the pick. It has the best zest, and feels the most fitting powertrain for this model. It sounds good, too. The auto transmission is pretty clever, there's easily enough pulling power, and it's probably going to be the last of the non-turbo V6s in Lexus's line-up when this cars life-cycle is up.

The IS300's turbo engine was the most disappointing, lacking some urge and constantly feeling bogged down by turbo lag, transmission confusion, or both. It felt underdone in enthusiastic driving, though in dull day-to-day commuting circumstances it came across as more acceptable, though the remapped transmission software was far less impressive in this application than in the IS350.

The IS300h was a lovely, quiet and refined experience all around. It’s the one you should go for if you don’t really care about all that go-fast stuff. The powertrain is proven, it accelerates with nice linear delivery, and at times it’s so hushed I found myself looking down at the instrument cluster to see if the car was in EV mode or if it was using the petrol engine. 

In driving the first Subaru Impreza WRX when it launched here in the early 1990s, the first attempt to control its surging, decidedly non-linear acceleration felt like pulling back on the reins of a bolting horse.

Subaru was in the thick of its commitment to the World Rally Championship (WRX stands for ‘World Rally eXperimental’) and the Japanese maker had a red hot product on its hands.

Fast forward to the 2024 version and the turbo torque still arrives with something of a rush but this is an infinitely more refined performance sedan than its relatively raw ancestor.

Subaru doesn’t quote a 0-100km/h figure but expect it to come up in the high five-second bracket and with maximum torque available all the way from 2000–5200rpm (and peak power taking over at 5600rpm) there’s always plenty or urgent acceleration available.

And that pulsing engine noise and percussive exhaust beat is still there in a no less distinctive and entertaining way. Our test car was fitted with the newly optional STi-branded exhaust ($2497, fitted) which adds to the aural impact. 

The gearshift isn’t ‘click-clack’ direct but it’s smooth and positive and the clutch is perfectly weighted. Such a pleasure to swap through the ratios, with a bit of old school heel and toe action thrown in for downshifts. Love it.

Subaru says the ‘Global Platform’ underpinning the WRX features a “full inner-frame construction” making it “14 per cent better in terms of front lateral flexing rigidity and 28 per cent stiffer torsionally” than its predecessor.

Suspension is strut front, double wishbone rear, which is a relatively sophisticated configuration allowing the WRX RS to combine impressive ride quality with excellent dynamic response.

The 245/40 Dunlop SP Sport Maxx rubber grips hard and steadfastly refuses to squeal or squirm in ‘press-on’ cornering, the AWD system defaulting to a nominal 45/55 front/rear torque split to deliver an initial rear-drive attitude with active torque vectoring helping to keep any pesky understeer in check. 

Push even harder and the system seamlessly adjusts the balance. And to top it off, the steering is great; accurate with good road feel.

Despite an alloy bonnet and front guards (even the fuel flap is resin) the WRX RS weighs in at 1482kg. That’s solid without qualifying as chonky, and it still feels nimble, responsive and balanced, helped in no small part by the boxer engine lowering the car’s overall centre of gravity.

The WRX has copped some criticism in the past about its braking performance under intense pressure. And while we didn’t hammer the RS around a race circuit we did repeatedly apply full-force to the centre pedal without any noticeable reduction in effectiveness. 

For the record, the system uses ventilated discs all around (290mm fr / 316mm rr) with dual-piston front calipers up front and singles at the rear. In everyday use the pedal is agreeably progressive.

Under the heading of general, mainly ergonomic, observations, the driver display may not be full digital but the 4.2-inch multi-information display in the centre of the instrument cluster delivers a healthy amount of relevant information clearly and simply.

At 11.2 metres the turning circle is okay, while vision for parking, supported by a high-def reversing camera is good. And applying the manual park brake is another reminder of the physical nature of this car.

The WRX is “unrated” by ANCAP (it’s maximum five-star rating timed out in 2022) but for the 2024 model year the RS manual picks up Subaru’s ‘EyeSight’ active (crash-avoidance) safety suite including features like AEB, adaptive cruise and more assists, warnings and alerts than you could poke a crash test dummy at.

Specifically, ‘Emergency Lane Keep Assist’, lane centring, ‘Lane Departure Prevention’, ‘Lane Departure Warning’, ‘Lane Sway Warning’, ‘Lead Vehicle Start Alert’, driver monitoring, rear cross-traffic alert, ‘Pre-collision Braking System’, ‘Pre-collision Brake Assist’, ‘Brake Light Recognition’, ‘Speed Sign Recognition’ and tyre pressure monitoring.

If an impact is unavoidable, there are seven airbags onboard, including full-length side curtains and a front centre bag to minimise head clash injuries in a side-on crash.

There are three top tether points and two ISOFIX anchors for child seats/baby capsules across the rear seat. 

On paper, Lexus’s ownership offer isn’t quite as enticing as some other luxury car brands - but it has a strong reputation for blissful ownership.

The Lexus Australia warranty period is four years/100,000km, which is better for duration than Audi and BMW (both three years/unlimited km) but not as accommodating as Mercedes-Benz or Genesis, each of which offer five-year/unlimited km warranty.

The company has a three-year capped price servicing plan, with maintenance every 12 months or 15,000km. The first three visits cost $495 each. That’s okay - but Lexus doesn’t offer free servicing like Genesis, and nor does it offer prepaid service plans - for three to five years for a C-Class, and five years for Audi A4/A5, for instance.

There is complimentary roadside assistance for the first three years, too.

That said, the company has its Encore ownership benefits program that allows a number of experiences and deals, and the service team will collect your car and return it, leaving you with a loan car if you need it.

Subaru covers the WRX with a five-year, unlimited kilometre warranty, which is still the norm in the mainstream market, although more than a few brands are stepping up to seven years.

The main service interval is 12 months/15,000km, also on par with the market and (five-year/75,000km) capped-price servicing is available.

Average is just under $535 per workshop visit, which is on the high side but maybe to be expected for a highly-tuned car like this.

That said, Roadside Assist is complimentary for 12 months, which is a nice sweetener.
