Lexus RX350H vs Mercedes-Benz Sprinter

What's the difference?

It’s hard to look past the value equation of the RX350h Luxury 2WD when comparing it to almost all its competitors. The pricing is on point, but there are some features missing.

However, there are very few (if any) rivals with a true hybrid powertrain (sorry, mild hybrids do not count), so the RX will capture buyers looking for environmental credentials and efficiency without going full EV.

The drive experience is much better than before and it’s all wrapped up in a very stylish package. The Lexus RX should not be ignored.

Given the original Sprinter was released in 1995, it’s not surprising the current third-generation model feels like it’s benefitted greatly from decades of continuous refinement. Although the list price difference between our test vehicle and its closest Chinese rival is substantial, the 417 MWB Panel Van is hard to fault in terms of driver comfort, safety and all-round competence. It really is very good.

Across its five generations, the RX has held significant visual appeal - especially the still-handsome second-gen version that was the first RX sold Down Under. The first-gen model skipped Australia.

The new model that launched in 2023 is a clear evolution of the car that came before, but it’s been softened and sharpened in the right areas, giving it one of the most appealing designs in its segment.

The proportions and design elements like the squat stance, unique C-pillar treatment, slimline headlights and nicely sloping roofline give it a sporty look.

In fact, I reckon it might be the best looking Lexus available today - not including the jaw-droppingly beautiful LC coupe and convertible, of course.

The interior is modern and feels like an evolution of Lexus’ previous cabin design - but elevated. The gloss black section of the dash helps here.

Levels built into the dash break up the bulk, but the interior is very grey. It could do with a dash of colour.

The synthetic leather seat trim doesn’t look premium. If you want a more expensive feeling RX, you need to pay more for a higher grade.

The 417 MWB Panel Van rides on a 3665mm wheelbase (the shortest of three Sprinter wheelbases) and is almost 6.0 metres long (5932mm), more than 2.0 metres wide (2020mm) and stands almost 2.4 metres tall (2378mm). Its 12.4 metres kerb-to-kerb turning circle is impressively tight for a vehicle of this length.

It rides on simple and rugged MacPherson strut front suspension, with a robust live axle/leaf-spring arrangement under the tail. Steering is via rack and pinion and it has disc brakes all around.

Look beyond the optional silver metallic paint on our example and there’s extensive use of unpainted dark grey plastic on all the external surfaces where hard-working vans are most prone to wear and tear, including the hubcaps, front/rear bumpers, grille, door-handles/mirror shells and along the sides.

Its work-focused exterior styling is nicely integrated, combined with an equally neat and functional interior design that offers a visually-pleasing combination of patterned fabric seat-facings and hard surfaces that blend different shades of grey with splashes of satin chrome and piano black.

We also like the feel and response of mechanical switches (rather than touchscreen prompts) for adjusting settings like cabin temperature, fan speed and media volume.

The RX is a five-seat only proposition in this generation - the previous model had a seven-seat option - so if you need a third row you can look at the Lexus LM people mover or massive LX 4x4 SUV, or at any number of other three-row lux SUVs like the Volvo XC90 or new Mazda CX-90.

That doesn’t mean the cabin isn’t practical. 

Up front the seats offer excellent comfort levels and ample upper body support, but not a lot of hip support.

Lexus has changed up the door handles for the new RX and it can be complicated - initially.

The interior handles bamboozled every new person that got in my press car over the three week loan. But once you realise it’s a simple push of the thumb on the handle’s thumbpad and a gentle push, it all makes sense.

Lexus calls the electrically activated door handles an ‘e-latch’. Is it tech for tech’s sake? Probably. 

I recently reviewed the Lexus LM and commented on how much I like Lexus steering wheels and that’s true of the RX, too.

It has clearly identifiable controls and feels nice in your hands. Thankfully, the cruise control buttons are housed on the wheel too, so no annoying stalk on the wheel.

There’s plenty of space across the front row so you should avoid the awkward driver-passenger elbow bump on the centre armrest.

Under the armrest is a huge central bin that opens on the driver and passenger side. There’s also a big covered storage nook forward of the shifter and another ledge above that, as well as a sizeable glove box. 

The doors have ample storage room for bottles, but the space is almost too wide. My bottle slid around when driving so I had to lay it down.

The centre console houses two big cupholders with adjustable depth in one of them. Clever touches like this and the central bin add to the appeal.

As with the Lexus LM, I am a fan of the new Lexus multimedia set-up. It has an easy-to-navigate menu along the side, easy wireless Apple CarPlay connection, and visually appealing graphics.

It’s a world away from Lexus’ previous system. That frustrating touchpad is, thankfully, in the bin.

I quite like the gear shifter with its unusual gate and even the indicator feels and sounds premium.

Small rear windows make for a rear three quarter blind spot, but visibility is otherwise good.

On a side note, the RX has very strong air conditioning - perfect for an Australian summer.

Jumping into the second row, there’s plenty of space all around and no shortage of head, leg, knee and shoulder room. Although foot room under the front seats is tight.

As with the front seats, the rear row offers comfortable seating. Kids should be happy back there.

There’s only a small transmission tunnel so middle-seat legroom is good. And in great news for passengers, the rear backrests recline. 

Lowering the 40/20/40 split-fold rear seats for more cargo space is done via a lever on the side of the outboard seats, or by a button in the boot area. There are ISOFIX clips on the two outboard seats.

Other amenities in the second row include map pockets, two USB-C ports, knee-level air vents, climate control, and a pull-down armrest with pop-open cupholders.

Open the power tailgate and you’ll find cargo space of 612 litres with all seats in place, or 1678L with the second row stowed.

That’s a decent amount of space but not class leading. The Mercedes-Benz GLE has 630L and the VW Touareg can swallow 810L.

There’s no under-floor storage because that’s where some hybrid hardware is housed. You will find audio speakers, nice carpet, a cargo blind, two 4.0kg hooks and three top tethers. No spare, only a tyre repair kit.

With its 2215kg kerb weight and 4100kg GVM, our test vehicle has a sizeable 1885kg payload rating.

It’s also rated to tow up to 2000kg of braked trailer and with its 6100kg GCM (or how it can legally carry and tow at the same time), that means it can tow its maximum trailer weight while hauling its maximum payload to ensure optimum versatility.

The cargo bay, which offers a cave-like 9.0 cubic metres of load volume and internal lighting front and rear, has internal dimensions of 3316mm length (with bulkhead), 1732mm width and 1719mm height.

So, with 1350mm between the rear wheel-housings, it can comfortably fit two standard 1165mm-square Aussie pallets or up to four 1200 x 800mm Euro pallets, held in place by a choice of 10 floor-mounted load-anchorage points.

The cargo bay is accessed through a single kerbside sliding door with a wide 1260mm opening, or symmetrical rear barn-doors with large handles on each pillar to assist operator access.

The barn-doors also have internal storage bins and open to a full 180-degrees to assist forklift and loading dock access. Thoughtfully, their hinge design also holds the doors firmly open at 180 degrees, to minimise the chance of wind gusts slamming them shut with potential injury to the operator.

There’s also plenty of cabin storage starting with two tiers of bins in each door, with the highest being spacious enough to hold large bottles.

There's also a deep shelf on the passenger side lower dash, a large lidded compartment in the central dash-pad and overhead shelves with lockable storage on the passenger side. Plus, the dash offers a total of eight cup/small-bottle holders.

The base cushion of the two-passenger bench seat is also hinged at the front, which allows it to tilt forward and provide access to a large hidden storage area beneath.

A crew of three can travel in relative comfort (for a commercial van that is) thanks to a central seating position that provides a sturdy hoop-handle for support, sufficient knee clearance from the dash even for tall people, and a reasonably flat and spacious floor area.

The cabin also features the latest next-gen 'MBUX' multimedia system with 10.25-inch touchscreen, which for the first time offers wireless connectivity for Apple CarPlay and Android Auto.

There’s also digital radio and enhanced functionality including an optional navigation upgrade with seven years of map updates.

Our test vehicle is the 417CDI MWB (Medium Wheelbase) Panel Van with standard roof height, which comes equipped with a 2.0-litre, four-cylinder, turbo-diesel engine and nine-speed automatic transmission for a list price of $86,018.

Our example is fitted with a couple of factory options, including the 'Cargo Pack' ($2265) which comprises a two-passenger bench seat, solid cabin bulkhead with fixed window and side-entrance assist handle, wooden cargo bay load floor and floor-to-roof wall-trim using 5.0mm-thick wood panelling.

It also has optional 'High-Tech Silver' metallic paint ($2534) which combined with the Cargo Pack raises the total price to $90,817.

In addition to the latest model’s upgraded safety (see Safety) and comfort/convenience (see Design) features, our test vehicle comes standard with 16-inch steel wheels and 235/65 R16C tyres plus a full-size spare, keyless start, steering wheel paddles for manual shifting, multi-function leather steering wheel, three USB-C ports and two 12-volt sockets, side marker lights and heated exterior mirrors.

There’s also daytime running lights, a parking package with reversing camera and front/rear parking sensors, traffic sign assist, tyre pressure monitoring and lots more.

Powering the RX350h is a series parallel hybrid system consisting of a naturally aspirated 2.5-litre four-cylinder petrol engine, a front-mounted motor and a nickel-metal hydride battery. 

Lexus doesn’t provide combined torque outputs for the hybrid, but total power for the system is pegged at 184kW.

This drives the front wheels only via a continuously variable transmission (CVT).

The (OM654) 2.0-litre, four-cylinder, turbo-diesel, which meets Euro 6 emissions standards using AdBlue, produces 125kW of power at 3800rpm with peak torque of 400Nm served between 1700-2400rpm. The nine-speed torque converter automatic offers the choice of sequential manual-shifting using the steering wheel-mounted paddles.

The official combined cycle fuel consumption figure for the RX350h 2WD is 5.0 litres per 100 kilometres, with CO2 emissions of 114g/km. You won’t get figures like that in a petrol or diesel competitor.

Over three weeks of mixed city, country, urban and freeway driving, I recorded 6.8L/100km which is not too bad given some of my spirited driving. The trip computer said 7.0L which is close to my figure.

The RX350h takes premium unleaded petrol and has a 65-litre fuel tank, so expect a range of around 950km based on our real-world consumption number.

The dash display was claiming average combined consumption of 9.5L/100km when we stopped to refuel at the completion of our 281km test, of which about one third of that distance was hauling a heavy payload (see Driving).

Our own figure of 11.7 (based on actual fuel bowser and tripmeter figures) was higher but still reasonable economy for a vehicle in this GVM class in mostly urban use.

So, based on our own figures, you could expect a ‘real world’ driving range of around 800km from its 93-litre tank, which has been enlarged from 71 litres as part of the latest upgrades.

The old RX was competent and even nice to drive but not a patch on the likes of the BMW X5. The new-gen RX improves on that in a big way.

It offers solid acceleration from a standing start. Lexus says 8.1sec from 0-100km/h - without giving you chills. The sportiest RX is the 500h Performance hybrid and that covers the same distance in 6.2sec.

The transition from electric power to petrol propulsion is more evident in this model than it was in the LM350h people mover I tested recently - the RX is a little noisier. The CVT doesn’t help this, offering up an uninspiring engine note.

It is, however, a much more fun car to push into tight bends than the previous RX. It remains reasonably flat in corners, and pulls out of tem with ease, but can’t compare to the dynamics of the dearly departed IS sedan.

The 19-inch tyres have large sidewalls and as a result soak up harsh bumps on the road. The non-adaptive suspension is tuned for better dynamism, meaning the ride quality is on the firm side.

The front-wheel drive RX lost traction for a second on a sweeping uphill section of my drive route, but the electronic traction systems otherwise kept the big SUV in check. 

But around town in urban areas, there is very little to complain about behind the wheel of the RX350h.

Large handles on the doors and overhead shelves assist climbing aboard and there’s enough adjustment in the well-bolstered seat and leather-rimmed steering wheel to find a comfortable position.

Driver views from all angles are excellent thanks to well-designed mirrors along with cameras supported by active aids like blind-spot monitoring etc.

The cabin, with its high roof relative to seat height, has a spacious and airy feel and all controls are reasonably intuitive and easy to reach.

Unladen ride quality is surprisingly supple for a vehicle with a 6.0-tonne-plus GCM rating, combined with excellent steering feel that strikes a fine balance between minimal turning effort at low speeds (for loading etc) and firm handling response at higher speeds.

The drivetrain is also energetic, pulling strongly and cleanly from 1000rpm even though its maximum torque is tapped higher in the 1700-2400rpm zone. The automatic transmission has admirable refinement, with near-seamless shifting between its nine ratios.

The Sprinter is also impressively quiet at speeds up to 80km/h. Tyre and wind noise (the latter mainly around the large door mirrors) naturally increase at highway speeds, but remain far from intrusive. And with the engine requiring less than 2000rpm to maintain 110km/h, it’s well-suited to highway work.

To test its load-carrying ability, we forklifted 1.3 tonnes into the cargo bay which with driver equalled a payload of 1.4 tonnes. That's still almost half a tonne less than its limit.

Not surprisingly, it handled this load with ease, as handling and braking were largely unaffected and the ride quality became smoother thanks to such a big increase in sprung weight. Even so, the rear springs only compressed about 30mm.

It easily conquered our 13 per cent gradient, 2.0km-long set climb at 60km/h with this load onboard, as the auto downshifted to fourth gear to tap maximum torque when hauling this load to the summit.

Engine-braking on the way down, in a manually-selected second gear, wasn’t as robust but not unexpected given a 2.0-litre engine trying to restrain 1.4 tonnes of payload on a steep descent. Even so, the quartet of disc brakes efficiently kept speeds in check.

Overall, it was an impressive performance. However, we did note that the speed sign recognition function was not working for the duration of our test. And some welcome enhancements would be a driver’s left footrest and a fold-down inboard armrest for the driver’s seat, as fitted to its smaller Vito sibling.

ANCAP ratings do not apply to Heavy Commercial vehicles. Even so, in addition to the Sprinter’s existing long menu of passive and active safety features, the latest range adds significant enhancements as standard equipment including thorax-protecting airbags for driver and passenger, lane-keeping assist, traffic sign assist, rain-sensing wipers, tyre pressure monitoring and a parking package with reversing camera and front/rear sensors.

Also new is ‘Moving Off Information Assist’ which utilises a camera mounted in the grille plus six ultrasonic sensors to monitor an area 3.7 metres in front of the steered direction of the vehicle and 0.5 metres to the side.

This automatically activates at start-up and remains active up to 10km/h. So, if a road user is detected in the monitored area, the driver is alerted by audible and visual signals.

The latest range also introduces ‘Sideguard Assist’ which provides extended detection in the blind-spot on the passenger side. It activates when the vehicle is stationary and at low speeds, providing an extra set of eyes during parking, low-speed manoeuvring and traffic congestion.

The RX350h is covered by a five-year, unlimited-kilometre warranty, and the servicing schedule is every 12 months or 15,000km.

There’s a capped-price servicing plan lasting five years and it will cost $695 per service. That's significantly less than some rivals like the Mercedes GLE.

The RX is covered by the 'Lexus Encore' loyalty program and includes complimentary service loan cars, fuel offers as well as discounts and other offers with Lexus partners.

Warranty is five years/250,000km whichever occurs first and includes a roadside assist support package.

Scheduled servicing is every 12 months/40,000km. Pay-as-you-go capped-pricing for the first five scheduled services totals $5905, or a pricey average of $1181 per year. Service plans are also available.
