Chevrolet Silverado vs Lexus RX

What's the difference?

With its unique V8 soundtrack, all-terrain capabilities and sumptuous comfort, the ZR2 is a quintessential American muscle truck that's as capable of carting crews and accessing rugged worksites during the week as it is towing boats, horse-floats and caravans or getting muddy on weekends. For either work or play, there's a lot to like here.

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

The Silverado’s extensive remanufacturing to RHD, performed on a purpose-built production line in Melbourne, meets OEM standards of fit and finish.

As the off-road focused 1500 model, the ZR2 has hardware and detailing consistent with its rugged bush-bashing persona, highlighted by aggressively treaded mud-terrain tyres and unique raised suspension with high performance dampers.

Other ZR2 features include a raised bonnet with ZR2 applique, ‘off-road cut’ front bumper, bash plates, black grille with ‘Flow Tie’ (flow-through) bow-tie motif, ‘Performance Red’ chassis-mounted front recovery hooks, concealed dual-outlet exhaust, black fender flares/door handles/bumpers/window surrounds and chrome ZR2 badges.

It has a tough and purposeful look with bluff-fronted styling and an imposing stance. 

An expansive length of almost 6.0 metres (5931mm) and a 14.4-metre turning circle highlight formidable (and at times impractical) dimensions for urban life.

The cabin is spacious and airy with a tasteful blend of contrasting tones and textures combined with many soft-touch surfaces, yellow stitching along seams and splashes of chrome and satin chrome creating a plush look and feel.

The RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

The ZR2’s hefty 2587kg kerb weight and 3300kg GVM results in a 713kg payload, which is modest given a seated crew of five big tradies could use up about two-thirds of that payload capacity before loading any of their gear.

It can also legally tow up to 3500kg of braked trailer on a 50mm ball and up to 4200kg on a 70mm ball. The latter figure is 300kg less than the LTZ due to the specialised off-road suspension.

However, given the ZR2’s 6851kg GCM rating (or how much it can legally carry and tow at the same time), you would be left with a mere 64kg of vehicle payload if you wanted to tow the maximum 4200kg.

That’s barely enough for a driver - and a light one at that. Fact is, few if any owners in real-world use would need to tow 4200kg, but it’s important to be across these legal limits if you’re planning to.

The load tub is protected internally by a spray-on liner and offers almost 1.8 cubic metres of load volume. Its load floor is 1776mm long, 1813mm wide and sits 569mm deep, with 1286mm between the rear-wheel housings. More than wide enough for hauling Aussie or Euro pallets.

There are also 12 load-anchorage points, power assistance for lowering the tailgate and a tub camera to keep an eye on loads when driving. The rear bumper provides surefooted tub access using either the centre step or concave side-steps.

All occupants enjoy luxurious space, particularly rear passengers thanks to easy entry created by the wide-opening doors, a flat floor with no transmission hump for the centre passenger to straddle and palatial head and legroom even for tall people. Combined with ample shoulder room, a full crew can travel in enviable comfort.

Cabin storage for the driver and front passenger includes two bottle holders and a bin in each door. There’s also a large glove box and the centre console has an open tray and two USB ports up front, two bottle holders in the centre and a big box at the back topped by a padded lid that provides comfy elbow support.

Rear passengers get a bottle holder and bin in each door, plus more USB ports and two more pairs of bottle holders in the rear of the centre console and in the bench seat’s fold-down centre armrest.

There’s also storage pockets on both front seat backrests and handy compartments for small items are cleverly concealed within the rear seat’s upper-backrest cushions. Its 60/40-split base cushions can also swing up and be stored vertically if more internal load space is required, or to access ample under-seat storage.

The RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

There are four variants in the RX range, and we’re testing the 450h+ Sports Luxury AWD, which sits just below the flagship and packs in plenty of premium kit for its $123,500, before on-road costs, price tag.

That makes it slightly more affordable than its main PHEV rivals; the BMW X5 xDrive50e (from $125,885 MSRP) and the Volvo XC90 Ultra (from $124,466 MSRP).

The Volvo does offer seven seats to the Lexus’ five, which may matter for larger families, and both rivals also outdo the RX on electric-only driving range - 65km in the RX compared with 77km in the Volvo XC90 and a generous 101km in the BMW X5.

Still, the RX fights back with a seriously stacked features list. Highlights include a panoramic sunroof, 10-way powered front seats with heating and ventilation, electrically folding rear seats (also heated and ventilated in the outboard positions), and a heated, power-adjustable steering wheel. Sound is taken care of by a premium 21-speaker Mark Levinson surround system.

Technology has had a solid upgrade with the 14-inch touchscreen multimedia display, 12.3-inch digital instrument cluster, digital rearview mirror, colour head-up display, live traffic navigation, wireless Apple CarPlay and Android Auto, 4G connectivity, four USB-C ports, one USB-A port and a fast wireless charging pad.

There’s also access to the 'Lexus Connected Services' app, allowing you to remotely lock or unlock the vehicle, pre-set the cabin temperature via three-zone climate control, configure driver profiles and even use your phone as a digital key.

Practical features include keyless entry and start, rain-sensing wipers, dusk-sensing LED headlights, rear sun-blinds, intelligent seatbelt reminders for the first two rows, a child presence alert and a hands-free powered tailgate. However, due to the plug-in hybrid system there’s no spare tyre, just a tyre repair kit.

Like the LTZ, the ZR2 is powered by a 6.2-litre petrol V8 producing 313kW of power at 5600rpm and 624Nm of torque at 4100rpm. It features cylinder deactivation to optimise fuel economy when full power isn't required.

This is paired with a refined 10-speed torque converter automatic, armed with an auxiliary external oil cooler ideal for heavy towing duties and off-road slogging. It also offers sequential manual shifting using steering wheel-mounted paddles and there are numerous selectable drive modes.

Its dual-range transfer case with push-button control offers the choice of '2WD High', '4WD High', '4WD Low' and '4WD Auto', with the latter being a full-time torque-on-demand system. It’s also equipped with driver-selectable front and rear locking differentials for optimum traction in the rough stuff.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

GMSV claims official combined cycle (urban/extra-urban) fuel consumption of 12.7L/100km and the dash display was showing 15.3 when we stopped to refuel at the completion of our 397km test, which included our usual mix of suburban, city and highway driving of which about half was hauling a variety of payloads.

This compares to our own figure, calculated from fuel bowser and tripmeter readings, which was higher again at 16.8L/100km. That exceeds the usual 2.0-3.0L/100km discrepancy between official and real-world consumption but is still acceptable for a 2.5-tonne pick-up powered by a big petrol V8 in urban use.

So, based on our real-world consumption figure, you could expect a driving range of around 540km from its relatively small 91-litre tank.

The plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

The ZR2’s raised off-road suspension requires more of a climb aboard than the LTZ, but the low-slung removable side-steps fitted to our test vehicle certainly make boarding easier and are an accessory worth considering if most of your driving is on-road.

There are large handles on the truck’s A- and B-pillars to assist entry to the cabin where the driver is treated to multiple power adjustments of seat and steering wheel plus a large left footrest, which together provide a very comfortable driving position.

The ride and handling are outstanding, as the ZR2’s suspension combined with the additional cushioning of its baggy all-terrain tyres is commendably supple over bumps, yet it's surprisingly responsive to steering input without the ponderous feeling expected in a vehicle of this size and weight.

This response is optimised when the ‘Sport’ mode is selected as it sharpens steering, brake pedal feel and suspension tuning for a more engaging drive. It also activates the louder and freer-flowing exhaust setting and modifies the auto’s shift calibration, which allows the V8 to shine with a guttural roar under full throttle that is not only an aural delight but can quickly reach triple-digit speeds with remarkable ease.

By contrast, it can also deliver relaxed and fuel-efficient highway travel thanks to the V8’s auto cylinder deactivation and less than 1500rpm being required to maintain a leisurely 110km/h. Engine, tyre and wind noise are negligible at these speeds.

To test its payload rating we forklifted 475kg into the load tub which combined with our crew of two equalled a total payload of 655kg that was within 60kg of its legal limit.

The rear leaf-springs only compressed abut 35mm under this loading, which left more than enough bump-stop clearance to ensure there was no bottoming out on our test route. The ZR2 performed so effortlessly with this payload it was easy to forget we even had one.

Our only criticism of the driving experience was the tri-fold tonneau cover. When hauling loads, this accessory is designed to fold forward into a flat bundle that leans against the rear of the cabin with two adjustable struts to brace it in place (see photo).

This worked fine during suburban driving up to 80km/h but was not suited to higher speeds, as the increased air pressure made it flex enough to block the rear-view mirror's camera view. So, an alternative tonneau design would be preferable for those needing to do lots of highway travel with uncovered loads.

The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

The RX earned a maximum five-star ANCAP safety rating in 2022, scoring highly across all protection categories: 90 per cent for adult protection, 89 per cent for child protection, 89 per cent for vulnerable road users, and 93 per cent for safety assist systems.

Standard safety gear includes eight airbags (dual front, front side, curtains, front centre, and driver’s knee) plus a comprehensive suite of driver aids. Standout features include emergency call functionality, child detection alert, side exit assist, front and rear collision warnings, park assist and emergency steering assist.

Additional tech covers blind-spot monitoring, driver attention monitoring, tyre pressure monitoring, daytime running lights, LED cornering lights, rear cross-traffic alert, lane departure alert, lane keeping assist, traffic sign recognition, and intelligent seatbelt warnings for the front two rows.

Visibility and parking are enhanced by a 360-degree camera system and front/rear parking sensors, while adaptive cruise control adds comfort on longer drives.

The rear seats have two ISOFIX mounts plus three top tether anchors, accommodating child seats safely. Autonomous emergency braking is active from 5.0 to 80km/h for pedestrians, cyclists, and backover and up to 180 km/h for cars.

Now comes standard with a class benchmark five years/unlimited km manufacturer warranty, plus five years of roadside assist.

Scheduled servicing is every 12 months/12,000km whichever occurs first, but there's no capped-price servicing. Expect a three year service bill of around $2000, which isn't outrageous for a vehicle of this type.

GMSV has an Australian network of 50-plus dealers across most states and territories and all dealerships can provide vehicle servicing.

The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.
