Lexus IS300H vs BMW 330e

What's the difference?

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.

The 330e M Sport is an excellent car, but it could be a much better hybrid.

In Australia, where driving distances can be vast, a car that's as comfortable and easy to live with as this one is welcome. But for the electric range to dissipate so quickly, and not recoup again at a fast enough rate without plugging into a charger, is disappointing.

There are other plug-in hybrids, even among the more affordable mainstream brands, which can return charge to the battery incredibly quickly and effectively on the go.

If you are looking to make the step into a hybrid, then perhaps consider a fully electric car. There isn't a battery electric 3 Series on the market in Australia (yet), but BMW does sell the iX1 small SUV for less money than a 330e or the iX3 for a tad more.

Both are pure electric SUVs and have a range of between 400-500km. You'll never need petrol again, which makes a hybrid seem outdated.

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.

Once upon a time sedans were all we drove, well mainly. Then SUVs became the style of car most people wanted. In fact, three out of four new cars sold in Australia today are SUVs.

So, I commend you on your choice of not just doing what everybody else does, and you'll be rewarded with better driving dynamics, and ownership of an iconic BMW - the four door, 3 Series.

And even though this is a plug-in hybrid version of the 3 Series it's identical in styling to the petrol variants. Only the light blue border around the BMW roundel is the indication that it's an electric vehicle. That and the charging flap near the left front wheel.

The M Sport pack adds some very sexy features such as the M Sport aerodynamic body kit, the door sills and M Sport seats, but the M Sport Pro Pack our car came with adds a black gloss grille, boot lid spoiler and the snazzy seat belts.

The cabin's double screens are impressive but I miss analogue gauges and found the digital instrument cluster overly busy and led more by cool design than functionality.

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.

People will tell you SUVs are more practical than sedans... and they're right, but not in as many ways as they probably think.

The cabins of sedans and SUVs of the same size are close in terms of space, but the 330e comes with excellent storage - better than many SUVs I've tested, featuring enormous door pockets, and a deep centre console storage bin.

There are four cupholders, too. Two in the fold down armrest in the back and another two up front.

There's also wireless charging up front, plus USB ports for the back passengers. The second row also has its own climate control and directional air vents.

Legroom is excellent in the back and I can sit behind my driving position with plenty of room to spare. Headroom is also excellent thanks to the tall roofline of the 3 Series.

Where a sedan isn't as practical as an SUV is its ride height, which makes getting in and out of the latter easier (although the 330e's doors open very wide) and its boot opening.

SUVs have hatch-like openings and that offers a wider and taller aperture for carrying cargo.

The 330's boot was still big enough to fit our two largest CarsGuide suitcases (see the video), but the location of the battery means cargo capacity has been reduced from 480 litres in a petrol 330i to 375 litres in this 330e.

The BMW 330e M Sport lists for $97,400, which is $4000 more than its 330i petrol twin.

The M Sport part of the name is there because the 330e comes standard with the M Sport pack. And that gives you a tough body kit, M Sport suspension, M Sport seats and aluminium trim, as well as M Sport door sills.

The car we tested and the one you can see in the video and images also comes with the 'M Sport Pro Package'. It costs $2800 and adds a boot-lid spoiler, glossy black grille and tail pipes, and M Sport seat belts, among other goodness.

This car also had the optional 'Visibility Package' fitted. It costs $4800 and adds a sunroof and adaptive LED headlights.

There's no direct rival for the 330e in Australia now. Mercedes Benz used to have a C300e, a plug-in version of its C-Class, but retired it locally some time ago.

The standard features of the 330e M Sport are identical to the 330i M Sport.

So, along with that M Sport pack also coming standard on the 330e is a head-up display, a 12.3-inch digital instrument panel, a 14.9-inch media screen with sat nav, Apple CarPlay and Android Auto, three zone-climate control, wireless phone charging, digital radio and power adjustable front seats.

Is it good value? There's a stack of equipment, tech, beautiful M Sport additions and it all feels superbly high quality. But knowing you can have a 330i for less means you're paying more just for the hybrid system. So, let's talk about that...

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.

The 330e M Sport has a 2.0-litre petrol engine and an electric motor. The engine makes 135kW while the motor produces up to 80kW, for a combined dollop of 215kW. Total torque is more than sufficient at 420Nm.

Acceleration to 100km/h from zero feels as quick as the 5.8 seconds BMW claims and that's also about a tenth of a second brisker than the 330i.

The 'XtraBoost' function combines the total output of both the engine and motor briefly providing that great acceleration.

An eight-speed automatic shifts gears smoothly with the drive going to the rear wheels.

I like all this very much - the responsive engine, the fantastic transmission, the extra oomph from the motor and the way it all works together seamlessly. It's just a shame it's not as efficient as some other new plug-in hybrids.

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.

The 330e M Sport is a plug-in hybrid which must be connected to an external power source regularly to charge its 12kWh battery.

The charging flap is located on the left side of the car near the front passenger door, which worked well for me as I could steer the 330e into my driveway and connect to a powerpoint on the wall using the charging cable provided.

It took me about six hours to charge the battery to 100 per cent from zero and that gives you a maximum 57km of electric driving range.

During my four days with the 330e Sydney's summer temperatures were hitting 34-degeres Celsius and with the climate control keeping the cabin at a hospitable 18C electric range was seriously cut short to about 40km.

I drove the 330e in hybrid mode nearly all the time - this is a hybrid after all. But there is a 'Sport' mode for more grunt and a 'Battery Hold' mode to save the charge for later.

I started with a full charge and a full tank of petrol, and for four days I lived with the 330e as I do with all my test cars.

I didn't aim to get the best fuel economy ever, nor was I wasteful with fuel. My wife and I, plus our two kids, just used it as our family car, doing trips to the beach, endless laps of the supermarket car park looking for a space, a birthday party, the lot.

I drove 154.7km over those four days and charged it on the second day after the battery was drained completely before driving another 70km or so over the next couple of days.

When I filled up after this it needed 7.74 litres to reach full again - it's a small 41 litre tank.

That converts to average fuel consumption of 5.0L/100km, which is bang on double the 2.5L/100km BMW says you should get.

I don't doubt you could get 2.5L/100km, but you'd have to be doing short trips and charging almost every time you weren't driving. And not use the climate control on an icy blast setting.

I've tested other plug-in hybrids that achieved much better mileage and that's because their on-board charging capabilities were excellent.

Some were even able to use the petrol engine to power the motor in reverse and therefore act as a generator to recharge the batteries fully.

The 330e M Sport doesn't do a good job of charging its battery while on the go. Sport mode does recoup charge to the battery, but again, if you're doing a long motorway trip that charge evaporates fast.

I don't think this type of plug-in hybrid is suited well to our country where we don't blink an eye at travelling 100km for Christmas lunch and then drive back again.

Also think about if you ever go on a trip away and don't have access to a power point or public charger. It's happened to me.

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.

The 330e M Sport is outstanding to drive. The driving position is superb, the steering is effortless and accurate, handling is excellent and the ride is beautifully comfortable.

Brake pedal feel is surprisingly good for a hybrid - some have a wooden sensation.

The transition from electric motor to petrol engine is also remarkably smooth.

Acceleration in Sport mode is sudden, with the engine and motor combining their mumbo to move you. There is a 'fake' or synthesised exhaust note in Sport mode, but it sounds convincing.

Speaking of sounds at lower speeds, in fully electric mode the 330e emits a warning tone to alert pedestrians of your presence. It's quite loud in car parks and does actually make people turn around looking for a UFO.

The 3 Series was awarded the maximum five-star ANCAP rating when it was tested in 2019. The 330e comes standard with AEB, lane keeping assistance, blind-spot warning and rear cross-traffic alert.

There are excellent cameras front and rear and LED headlights, too.

Adaptive cruise control is also standard on the 330e M Sport.

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.

The 330e M sport is covered by BMW's five-year/unlimited kilometre warranty. The hybrid battery is covered by a six-year/100,000km warranty.

BMW offers a five-year/80,000km service package for the 3 Series for $2150.

Service intervals are condition-based, and the car will let you know when it's time for a check-up.
