Lexus RX450H vs Mitsubishi Outlander

What's the difference?

The RX is a little frustrating - it's going after Mercedes and BMW and Audi in a hotly-contested space and falls over in a couple of key areas. The media/sat nav system is hopelessly outdated and the drivetrain fails to deliver a significant performance or fuel benefit (although, given its 2.2 tonnes, perhaps it delivers a miracle).

It does come with a rock-solid, scandal-free reputation, a reputation for spectacular customer service, it has a lovely cabin and it's certainly an individual looker. For plenty of people, that's quite enough.

The Outlander PHEV in GSR spec is a nifty daily driver, quietly appealing and more than capable of heading off-road as long as you drive it well within its AWD limits.

If you reside in the city or suburbs and your daily driving is not too punishing in terms of distance, then this PHEV makes a lot of sense. A hybrid vehicle is a happy-compromise move towards an EV future – and the Outlander PHEV is a big step in the right direction.

There's a lot of RX and there's a lot going on in that creased, folded and teased sheetmetal. It's a unique design, with a huge 'spindle grille', big lights and the fast glass both front and rear.

It positively screeches Lexus DNA and was a polarising force on our driveway for the week. Most weren't sure, but knew for certain it was a Lexus.

Aggressively flared wheelarches like this aren't common on SUVs (although the squared-off ones are). It's right up on stilts, but the 20s you find it rolling on help to reduce its visual bulk.

That wacky rear quarter glass reminds me of the BMW i3's but it's a Lexus SUV signature. It's quite striking. Do I like it? Not really, but that's completely subjective. You can tell, though, it's built tight as a drum.

Inside is a bit calmer, beautifully laid-out and built to last. The materials are almost all top notch, with lovely switchgear and the real leather is really nice.

There is absolutely nothing avant-garde in there (apart from maybe the pinstripe effect on the centre console), it's all terribly comfortable and easy on the eye. But not exciting, though not all Lexuses are.

This particular car is very US-centric and, if I may, a particularly sunny and humid part, so it can't be too wacky.

In terms of exterior dimensions, this PHEV is 4710mm long (with a 2706mm wheelbase), 1862mm wide and 1745mm high.

The Outlander is an inoffensive-looking AWD wagon with an appearance every bit in line with its GSR spec and price-tag without going over the top.

On the outside, this top-shelf GSR incorporates Mitsubishi’s 'Dynamic Shield' design facade, which was divisive in its early years but has since attracted its fair share of fans.

On the inside, this Outlander has black leather-appointed upholstery with silver stitching, the same treatment applied to the soft-touch armrests, centre console top, sections of the dash and elsewhere.

And the big 20-inch machined alloy wheels top off a classy yet relatively subdued overall look.

In the realm of medium-sized city-going SUVs with weekend road-trip inclinations – think Hyundai Santa Fe, Kia Sorento, Kia Sportage and the Outlander’s hybrid rivals like the Nissan X-Trail e-Power, Toyota RAV4, et al – this Mitsubishi AWD more than holds its own because in terms of design none of them are bound to set hearts a-flutter. But they’re all fine. 

There is plenty of room inside this big unit, which is very welcome. Front seat passengers have lots of storage, such as a deep central bin under the armrest, dual cupholders and big door pockets with bottle holders.

Step into the rear and there is a ton of leg and headroom although the transmission tunnel intrudes slightly for the middle passenger. Chuck them out, drop the armrest and you have two more cupholders and each door has pockets and bottle holders.

The boot is pretty big considering the angle of the rear glass. You start with 453 litres (but an expanse of flat floor), which rises to 924 litres with the split-fold seats down. That seems conservative given just how much space you appear to have.

This SUV has a family-friendly and functional interior with a premium feel, even if it does seem somewhat underdone for the price.

But it has all the right elements of a family tourer, in a cosy cabin in which it’s easy enough for driver and passengers to spend a chunk of time on lengthy road trips without complaint. I know, because we did.

The GSR has comfortable leather seats, a (mostly) user-friendly multimedia system, plenty of charge points (USB-A and USB-C up front and two USBs for second-row passengers), lots of soft-touch surfaces and a reasonable amount of storage space peppered throughout.

Nice touches, such as the heated steering wheel and heated front seats, which also have the massage function, top off what is an impressive interior.

There is wired charging for smartphones with Apple CarPlay or Android Auto, as well as a wireless charging pad. There are also 240V/1500W power outlets.

The 9.0-inch multimedia touchscreen is too small for me (perhaps a case of Old Bloke Eyes?), but it’s better when engaged in Apple CarPlay mode. The 12.3-inch high-resolution digital driver display is simple enough to use, and the 10.8-inch head-up display is a handy feature.

The driver has an eight-way power adjustable seat, so they’re able to dial-in their favourite driving position.

As stated, this Outlander’s seats are comfortable with a reasonable amount of room for everyone, though the third row is a tight fit for anyone other than children.

The second row is a 40/20/40 split configuration, while the third row is 50/50.

In terms of packing space, there is 191 litres in the rear cargo area when all seats are being used, 461 litres when the third row is folded flat, and 1387 litres when the second and third rows are stowed away.

The seven-seat 2024 Mitsubishi Outlander PHEV GSR is the top-shelf variant in a five-model PHEV AWD range and has a price-tag of $73,790, excluding on-road costs. 

Standard features include a 9.0-inch multimedia touchscreen, a 12.3-inch digital driver display, wireless smartphone charging, a nine-speaker BOSE sound system, multi-zone climate control, a leather-trimmed steering wheel, head-up display, heated massage front seats, two-tone leather-appointed seat trim, a panoramic sunroof, a powered tailgate and 20-inch alloy wheels.

Exterior paint options for the GSR are, 'White Diamond', 'Red Diamond', 'Black Diamond' or 'Graphite Grey'.

Note: The Outlander does not have a spare tyre – not even a space-saver.

The Outlander PHEV has few to no rivals in the mid-size SUV segment, certainly none that can offer anything near Mitsubishi’s (conditional) 10-year/unlimited kilometre warranty.

You can choose three different powertrains in the RX - a 3.5-litre V6, a 2.0-litre turbo four-cylinder, or this one, the 3.5-litre V6 with hybrid.

As a series hybrid it can run for short distances on electric only before firing up the V6 to supply charging and motivation.

The 3.5 produces 193kW/335Nm along with the electric motor. That torque figure seems low and it probably is, but that's a function of the weird way of measuring torque from a hybrid unit. The combined power figure, however, is 230kW.

The hybrid system is hooked up to Lexus' CVT auto and sends power to all four wheels. Lexus says the 450h will complete the sprint from 0-100km/h in 7.7 seconds, which isn't bad for a 2210kg SUV.

The Outlander PHEV has a 2.4-litre four-cylinder petrol engine producing 98kW at 5000rpm and 195Nm at 4300rpm, an electric motor on the front and rear axles, and a lithium-ion battery pack with a total capacity of 20kWh.

Combined output (engine and electric motors) is 185kW and 450Nm and this PHEV’s electric-only driving range is listed as 84km on a full charge.

It has a single-speed transmission and drive modes include 'Eco', 'Normal', 'Power', 'Tarmac', 'Gravel', 'Snow' and 'Mud'.

It has three power-use settings: 'EV Mode' for low to medium speeds urban running, 'Series Hybrid Mode' which allows the petrol engine to step in for urgent acceleration or climbing hills and 'Parallel Hybrid Mode' for highway overtaking where the vehicle runs on engine power with electric assistance.

The official combined cycle figure is listed as 5.7L/100km. And, uh, yeah, we didn't get that. I did manage 8.9L/100km over the week, which included a long motorway run from Sydney up to the Blue Mountains (a roughly 160km round trip).

The Mitsubishi Outlander PHEV GSR has a listed fuel consumption of 1.5L/100km on a combined (urban/extra-urban) cycle but, as with all official fuel figures from any carmaker, you can take it with a hefty grain of salt.

That said, if your daily driving distances are within this PHEV’s electric driving range (84km, as listed) and you’re able to drive in EV mode most of the time, then at the very least you will have chopped your fuel bill.

On this test, dash-indicated fuel consumption was 5.8L/100km; actual fuel consumption, as measured from pump to pump, was 7.7L/100km.

The good news is the Outlander PHEV runs happily on the cheaper 91RON 'standard' fuel.

Our dash-indicated power usage was 20.8kWh/100km. This PHEV gobbled through most of its 20kWh battery capacity quite swiftly on the drive from the vehicle pick-up point in Sydney to our test start-point just over 100km away.

It recouped 10km electric driving range via regenerative braking on a series of long downhills when set to ‘Charge’ driving mode (with the combustion engine generating power to the battery), but I had to cycle through regen modes to optimise that power regain.

The dash-indicated combined driving range (battery and engine) was 748km on a full charge and a full 56-litre tank.

Mitsubishi states that if you’re charging off a standard household power point it will take “approximately” 9.5 hours to fully charge your Outlander – or 6.5 hours if you’re using a home or public charging device.

Things speed up considerably if you use a public rapid recharging station. In that case, Mitsubishi says your Outlander Plug-in Hybrid EV will reach 80 percent battery capacity in 38 minutes.

Right. So this is a salutary lesson about tyre pressures. The first few days the tyres were only pumped up to 200kpa (29psi). That's an easy 100kpa (14psi) short of the required 300 (43psi).

Every time I, or my wife, went around a corner, the big Dunlop Sport Maxx SPs would squeal and squirm and it was most unsatisfactory.

So check your tyres, because the extra 100kpa makes all the difference. Also, the number of service stations it took to find a working pump was unacceptable. Pull your socks up, Sydney.

Anyway.

Correct tyre pressures enacted, the big Lexus turned into a comfortable, competent cruiser. Its motorway performance is super-impressive, purring along the M4 and it's ridiculously poor surface like it was born to it. Which it sort of was.

The hybrid drivetrain allied to the CVT is mostly whisper quiet. It's not the most responsive combination, the initial step-off of the electric motor's torque soon giving way to the rubber band effect of the transmission.

It doesn't feel as swift as the claimed 7.7 seconds and it would be nice if the drive select dial made a genuine difference to the throttle and transmission's response.

In the city, it's a proper wafter, moving about the broken down city streets of Sydney without fuss and a plush ride that's a bit of a surprise given the huge wheels and substantial weight of RX.

It's all very easy and pleasant but the wild looks do not match the experience. Which is not a criticism, just an observation.

As mentioned earlier, hybrids are your best buy at this moment in time, if you want to help save the world from climate-change disaster, avoid range anxiety, and save some money on fuel bills – all without having to sacrifice safety, comfort or features.

And – bonus – the Outlander is quite nice to drive. Not to mention a pretty handy light-duty off-roader. But more about that later.

It has a kerb weight of 2145kg with light but sharp steering and a tight (11.2m) turning circle so it’s an easy vehicle to manoeuvre around busy city and suburban streets.

The teaming of a 2.4-litre four-cylinder petrol engine and two electric motors works seamlessly well. There's always plenty of power on tap and, no matter how energetic your driving becomes, this Outlander remains smooth and quiet.

Throttle response is sharp and there’s plenty of punch off the mark as well as zippiness around town when you need it.

The PHEV’s EV-only driving range is a listed 84km but our test vehicle chewed through most of its battery power on a 110km highway trip through hilly territory.

Regenerative braking regained very little of that used power and the Outlander switched to rely on petrol for the remaining 30km or so of that trip.

The driver is able to adjust the degree of regenerative braking via paddle shifters on the back of the steering wheel: use the left to add more and the right to ease up.

The drive mode options tweak engine, electric motor, transmission and other factors to suit the selected set-up.

Other than that, ride is quite firm, handling is civilised and, overall, this Outlander is rather pleasant on sealed surfaces.

And, as I alluded to earlier, it’s surprisingly comfortable and capable off-road – as long as you stick within the parameters of the kind of 'off-road' terrain an AWD SUV is built to cope with: well-maintained gravel roads and dirt tracks with minor corrugations in dry conditions… or, at worst, rain-puddled blacktop.

The Outlander has satisfactory off-road measures for a city-focussed vehicle: of 18.3 degrees (approach angle), 22.2 degrees (departure), 18 degrees (ramp breakover) and 203mm of ground clearance (unladen). 

It feels nimble in the bush because steering is light and precise, visibility is good all-around, and the vehicle settles well on gravel and dirt tracks at speed, only ever skipping around a bit on rougher sections, due to its firm suspension and road tyres.

You can switch drives modes to either Gravel, Snow or Mud to best suit the terrain on which you’re driving but with the Outlander’s lack of ground clearance, road-biased tyres and 20-inch wheels, this SUV is hamstrung by its city-biased physicality.

But, this is still a handy dirt-road tourer, yielding comfortable and controlled ride and handling, only ever becoming rattled when the road or track surface becomes very chopped up and bumpy.

The Outlander’s 'Super-All Wheel Control' (S-AWC) system deserves a fair amount of credit. This traction control system manages torque application so it is instantaneous, and delivers drive with impressive levels of throttle control and an even-handed management of power.

Worth noting the Outlander did, of course, go through battery capacity at a faster pace off-road than it did when we were on sealed surfaces .

Off-roading, by its very nature, is more difficult and demands more of a vehicle than driving on smooth sealed surfaces does. And, for that reason – and the fact the Outlander is quite low – I’d avoid driving this SUV on terrain more challenging than well-maintained gravel roads and dirt tracks with minor corrugations in dry conditions.

I’ve driven an Outlander PHEV on sand before and it taxes the capacity even faster.

As mentioned earlier, this Outlander does not have a spare tyre. The absence of a spare – even a space-saver – is a disappointment, especially if you’re considering using your PHEV as a touring vehicle. A puncture repair kit is provided.

Payload is listed as 605kg, towing capacity is 750kg for an unbraked trailer and 1600kg braked. GVM is 2750kg and GCM is 4350kg.

The Mitsubishi Outlander has the maximum five-star ANCAP safety rating from testing in 2022.

It has eight airbags (driver and passenger front, driver and passenger front side, driver knees, centre and curtain) , as well as a comprehensive suite of driver-assist tech including AEB (with pedestrian/cyclist/junction assist), adaptive cruise control, blind-spot assist, lane departure warning, lane-keep assist, driver attention monitoring, emergency lane-change warning (with auto braking), traffic sign recognition, front and rear parking sensors as well as an around-view monitor.

There are two ISOFIX child seat anchors and three top-tether points across the second row.

Lexus offers a fence-sitting four year/100,000km warranty with roadside assist thrown into the bargain for the same period. 

Service intervals arrive at 12 month/15,000km and there is, sadly, no capped-price servicing.

Lexus will, however, promise you a car for the day or come and get your car from you and drop it back when the service is done. And it will be washed and vacuumed. The website makes a big deal about that.

The Outlander range is covered by a 10-year/200,000km warranty – as long as servicing is completed on time by an authorised Mitsubishi dealership (otherwise, five years/100,000km) – and 10 years capped price servicing and 12 months roadside assist.

Outlander service intervals are scheduled at 12 months or 15,000km. Service costs can officially range from $349 through to $799 for a 10-year average of $549 per workshop visit.

The battery set-up has an eight-year/160,000km warranty.
