Lexus IS300 vs Toyota Supra

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.

The Toyota GR Supra GT is a superb sports car that’s relatively easy to live with in the city even with the manual gearbox and incredibly fun to drive out where the roads are free from traffic.

Not only is the GT great for the price compared to rivals but it’s the pick of the Supra range.   

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.

Perhaps it’s just me but I think the Supra looks exactly how it should look - like a Hot Wheels car.

Seriously, how good does the back view look? I love the spoiler that angles up like a crazy ski jump and the tail-lights integrated underneath it.

I love the huge rear hunches swollen like they’ve been stung by an enormous wasp. Check out the roof - see how it’s curved? And that bonnet with the vent above the wheel arches, I love the styling of every millimetre of this car.

But my neighbour doesn’t. I pulled up and said, “How good does this look?” And he gave me this stare like I was bonkers.

I don’t know, maybe you and I have the same excellent taste, but if there’s anything I hate it's anything that’s boring.

To me the BMW Z4 ‘twin’ is getting very close to the boring end in the styling department. 

Talking of BMW, the Supra's interior is very BMW from the indicators stalks to the media system and climate control set-up.

It’s a modern and minimalist cabin… if only there wasn’t a cupholder right where my elbow goes. That’s a good place to stop and talk about the Supra GT’s practicality. 

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. 

The good news is that if you’re tall like me (189cm) and mainly legs then you’ll have more than enough legroom and headroom because the footwells are impossibly deep and the seats can be lowered to what feels like ground level.

Actually, you are almost at ground height in this car so the bad news if you’re as tall as me you’ll probably have to crawl out of the car on all fours.

The cabin of the Supra doesn’t do the storage space thing well. Sure there are two cupholders but their location is the same place my elbow frequents while changing gears and resting.

The wireless phone charging area is good and easy to access, but the door pockets are as thin as post box slots so if it’s letters you’re storing there you’re in luck.

If it’s anything thicker than that you’ll be left looking around for a place to put your purse or wallet and end up throwing it in the phone charger space if the passenger seat is taken.

You could always ask your co-pilot to hold onto your things which reminds me to tell you that the Supra is a two-seater only. There are no back seats, and there’s no option to have back seats.

If you’re looking for a sports car with rear seats (although space will be limited) for the same money then there’s the Audi A4 45 TFSI and at an even lower price is the Ford Mustang GT.

If you look over your left shoulder while in the driver’s seat of the Supra GT you’ll see into the boot -  there’s no wall separating the cabin from the cargo area. This is handy for throwing a school bag in as I did for my son on the morning drop off, but also means your items may make an unexpected visit to the cockpit if you stop suddenly.

The boot is large for a sports car at 296 litres (VDA) and it managed to fit our large CarsGuide suitcase with space to spare as you can see in the images.

The Toyota GR Supra GT with the manual gearbox lists for $87,380 and you’ll pay the same price for the same car with the automatic transmission. 

Yes, almost $90K might sound like a lot of money for a Toyota (unless it’s a LandCruiser) but it’s actually a bargain considering the GTS grade above costs $10K more and has the same engine plus pretty much the same features apart from a fancier stereo, head-up display and 19-inch alloys (rather than the 18s on this GT).

Also, if you didn’t know already the Supra is a BMW/Toyota joint venture model aligned with the BMW Z4, and if you want the Beemer version with the same engine as the Supra GT you’ll pay $139,800 for it.

So see, it’s a bargain in comparison.

The standard features list of the GT has pretty much everything you need. There’s a proximity key, LED headlights with adaptive high beam, active cruise control, sat nav, wireless Apple CarPlay and Android Auto, a 10-speaker stereo, wireless phone charger, heated and power adjustable seats, shifting paddles and sports pedals. 

Great features, but let down only by a small 8.8-inch screen for your media and nav. Still, that absolutely shouldn’t be a deal-breaker for you.

The rivals? Well, clearly the BMW Z4 which is way more expensive, but also there is the Nissan Z which costs between $70-$80K and is also a hoot to drive.

Add the Ford Mustang GT to your research list, as well. It’s not as agile as the Supra but it’s quick, fun and sounds better to my ears. 

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. 

You’re looking at a Supra that could be the peak of its model evolution because since the generation’s arrival in 2019 Toyota has increased the power of the 3.0-litre turbo-petrol in-line six-cylinder from 250kW to 285kW (torque remains the same at 500Nm) and introduced a six-speed manual. 

This 3.0-litre six-cylinder turbo-petrol is the only engine you can have with the Supra, there are no four cylinders or V8s - now there’s an idea. 

Toyota says the 0-100km/h time for the GR Supra with the manual gearbox is 4.4 seconds and 4.1 seconds for the automatic which comes with a ‘launch control’ feature.

Of course, all Supras are rear-wheel drive.

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.

Toyota says the 3.0-litre six-cylinder straight-six turbo-petrol engine in the Supra GT paired with the six speed manual gearbox should use 8.9L/100km after a combination of open and urban roads.

I did a week’s worth of city commuting and then a couple of hundred kilometres on country roads, but no motorways and the trip computer told me I was averaging 10.3L/100km.

Not bad for a big engine in a car tuned for performance, driven by a big kid who feels like he’s playing with somebody else’s toys.  

Premium 95 RON fuel is recommended, although 'standard' 91 is acceptable. A 52-litre fuel tank translates to a theoretical range of around 580km, dropping to approximately 500km 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. 

Ah, but what about living daily with a manual? As a car enthusiast most of the cars I’ve owned have been manuals and I’ve rarely cursed them because I love to drive.

But there were times when they were a pain, such as in traffic, or in traffic on steep streets and in traffic in shopping centres. Did I mention in traffic, also?

But on the nice roads with bends and dips, hills and sweeping corners, hairpins and twisty parts in places without traffic, then all is forgiven. 

And so it goes with the manual version of the Supra. 

Making life easier in the Supra GT is a clutch pedal without much travel so you don’t feel as though you’re at the gym doing a one-sided leg press.

I found the shifts themselves, while short, to be less than smooth. At first, I thought that the clunky changes might have been because the gearbox hadn’t been run in yet, but the odometer was saying 7500km, so this could just be the nature of the gearbox and after a few days I became used to it.

The rev-matching feature of this gearbox is a nice touch, especially on those sporty drives when you change into a gear and you’re thrown straight back into the power band again.

Superb balance, great steering with a nose which points exactly where you want it to and that magnificently smooth turbo-petrol in-line six posting all its meaty grunt to the rear wheels just behind your shoulders makes for a sports car that’s fun, talented and quick.

Good brakes (348mm ventilated rotors with four piston calipers at the front and 330mm discs with single piston calipers at the rear) and grippy Michelin Pilot Supersport tyres (255/40 fr - 275/40 rr) complete a great package. 

A ride that’s still comfortable over bad Sydney roads and surprisingly good visibility made the Supra easy to live with in the city, from parking to school drop offs.

Yes, used it each day for the school run with my older child and the grocery shopping. 

The GR Supra GT has not been crash tested by ANCAP, but its BMW Z4 twin scored a maximum five stars when it was tested by the European equivalent Euro NCAP.

Still, the Supra has seven airbags, there’s AEB with pedestrian and cyclist detection, lane keeping assistance and blind spot warning, plus front and rear parking sensors. There are seven airbags on board.

There’s no spare wheel, but there is a tyre inflation kit which should get you out of trouble.

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.

Toyota covers the GR Supra GT with its five-year, unlimited kilometre warranty. Servicing is required every 12 months or 15,000km and is capped at $415 per service.

The warranty is the industry standard in terms of time and kilometre length, and the capped service prices are very reasonable - a lot more affordable than a car with a prestige badge on the bonnet, too.
