Range Rover vs Mercedes-Benz Gls450

What's the difference?

The Range Rover Autobiography long wheelbase is an outstanding SUV that is not just beautiful to drive but makes family practicality a priority, too, 

The price is reasonable relative to the competition, the features list is long and complementary servicing offers peace of mind.

If you don’t need the third row, I’d consider the standard wheelbase Autobiography even if it does reduce legroom, there’s still plenty of space.

My son stopped short of giving the Range Rover Autobiography full marks "because there are no massaging seats in the second row".     

The GLS450d impresses as an entry-level grade, as it’s a more family-friendly allrounder than the specialised AMG and Maybach variants. Its combination of a torque-rich diesel 48V hybrid drivetrain, air-cushioned suspension and plush interior are as well suited to luxury urban travel as they are to grand touring, where its heavy towing and generous load-carrying capabilities can shine. Whether it’s worth around $200K drive-away, only those who shop at the top end of town can decide.

This fifth-generation Range Rover debuted in 2021 and despite its smooth, modern styling this SUV retains the familiar traditional Range Rover look with the short squared bonnet, flat roofline and tall windows.  

Let’s talk about the wheelbase, because it has a huge impact on passenger space.

We had the long wheelbase which is 3197mm between the front and rear wheels - that’s 200mm more than the standard wheelbase. 

Just look at those stretched rear doors in the photos - this is a go-anywhere limousine, or go-anywhere daycare centre in my case.

The overall length of the long wheelbase Range Rover is 5252mm. That’s big, but the design of this SUV doesn’t make it appear enormous.

What I don't like are the retractable door handles. They take a while to pop out and they look and feel cheap. Land Rover has used these on its other SUVs and if I had time I’d pen a letter asking the company to please stop. I’m sincerely hoping this review will do the same thing. I await your response JLR.

I think the tail-lights are pure genius. The pencil thin design is such a brave move away from the norm where brands are going over the top with LED lighting, and the simplicity is refreshing.

Inside, a traditional-looking Range Rover cabin awaits you with the flat dashboard, the low window sills contrasted by super modern touches like the displays and fully digital dials.

It’s sumptuous, luxurious, but not over the top. Again some people are looking for bling and gimmicks, but you won’t find them here - and I like that. This interior feels solid and substantial, but plush. 

This is an imposing vehicle in extravagant S-Class tradition, riding on an expansive 3135mm wheelbase and stretching more than 5.2 metres (5215mm) long and more than 2.0 metres (2030mm) wide with a turning circle that's nudging 13 metres.

However, it’s just under 1.8 metres (1798mm) tall, so there’s no clearance issues when accessing multi-storey carparks. And with its side-steps (or ‘running boards’ in nostalgic Benz speak) most adults can step rather than climb aboard, although passengers of shorter stature during our test noted that assist handles on the A and B pillars would be handy.

Central to its sophisticated chassis design is adaptive air suspension, which uses a pneumatic or ‘airbag’ form of springing with adaptive damping to continuously optimise ride comfort and handling response according to road conditions and driving dynamics (see Driving).

The GLS’s styling is clean and uncluttered with tasteful restraint evident in its chrome and satin-chrome highlights, yet it projects a majestic quality with its prominent four-louvre grille and elegantly spoked alloy wheels.

The spacious and sumptuous seven-seat interior is visually pleasing and practical, with a subtle blend of surface treatments, contrasting tones, lots of soft-touch surfaces and exposed stitching. This is combined (thankfully) with physical dials, switches and ‘piano key’ buttons to control numerous interior functions, in preference to distracting touchscreen prompts.

Range Rovers have been a family favourite for decades and they’ve been doing school runs and trips away long before other brands even thought about producing SUVs for families.

So what you’re buying is Land Rover’s decades of knowing how to make a family SUV and you can tell by little things such as, how wide the doors open, how easy it is to get in and out of (even for little kids), the flat floor, the good visibility (thanks to low window sills), and then there’s the space and cabin storage. Stuff other brands seem to be still working out.

The second row seats in the Autobiography have electric sun shades, dual-zone climate control and the window seats are power adjustable and heated.

My eight-year old couldn’t resist playing with his electric sunshade and the seat adjustment, but fortunately the driver has an override switch which let me turn off his 'seat privileges’ as he called it. 

Being the long wheelbase means the rear doors are long and heavy. So while the eight-year old could open them, he had trouble closing them. 

The long wheelbase offers unrivalled legroom in the back and that meant my wife and I could put our own seats back further for our own comfort -even with a baby seat behind us.

Enormous door pockets, a giant centre console storage area, cupholders in all three rows, USB ports, wireless phone charging and in our case an optional domestic power outlet ($130) made this a comfortable, roomy, well equipped cabin.

Sure, the third row isn’t exactly spacious, but I’ve never met one that is. 

The intelligent seat folding system is remarkable. From the boot or side doors you can electronically adjust the second and third rows - either to raise them or lower them so they are flat for storage.

With all seats in place there is 229 litres of cargo space still left in the boot, but with those back seats folded flat you have 713 litres of capacity - and that’s just up to the cargo cover. 

The Range Rover Autobiography has air suspension and this means the SUV can lower itself to an 'Access' height to make it even easier to get in and out.

Although it has a hefty 2655kg kerb weight, our test vehicle’s 3420kg GVM rating provides a useful 765kg of load capacity, which should comfortably absorb the combined weight of up to seven occupants and light luggage. Or with the third row of seating folded, five occupants and heavier luggage.

It’s also rated to tow up to 3500kg of braked trailer and with its sizeable 6920kg GCM (or how much weight it can legally carry and tow at the same time) it can carry its maximum load while towing its maximum trailer weight.

So, that’s commendable practicality, given it would be well suited to owners that need to tow large caravans, boat trailers, horse floats etc in style without having to compromise much (if at all) on either passenger numbers or luggage capacity.

Driver and front passenger space and comfort is exceptional, as you’d expect. Storage includes a large glovebox plus a bottle holder and bin in each door. The front of the centre console has two USB-C ports, wireless phone charging and heated cupholders, while the rear of the console has a large storage box with a third USB-C port and padded lid that doubles as a comfy elbow rest.

Even tall passengers in the second row of seating enjoy spacious comfort, given I’m 186cm and with the driver’s seat set in my position I have ample knee clearance, foot room and head space.

However, the central passenger must contend with a transmission tunnel in the floor and shoulder room would be squeezy for three large adults, which is okay for short trips but a maximum of two would be ideal for longer journeys.

The rear of the centre console also treats second-row passengers to a pair of USB-C ports, adjustable air-vents and a control panel that allows independent climate adjustment.

There’s also a large bin/bottle holder in each door plus storage nets on each front seat backrest. The centre seat backrest folds flat to allow long items (skis etc) to slot between the outer backrests. And it also serves as a fold-down armrest, containing two cupholders and a lidded slimline compartment that’s ideal for hidden phone storage.

The third row is uncommonly spacious, even for tall people, with padded armrests on each side containing cup holders and twin USB-C ports.

The carpeted rear luggage area has four load-anchorage points, a first aid kit and 12v socket. With the third-row seats upright it offers 355 litres of load volume, which increases to 1350 litres with the third row folded and 2400 litres (or 2.4 cubic metres) with both the second and third rows folded.

Our Polar White test vehicle, which is the base grade in the three-tiered GLS range, comes standard with a 3.0-litre inline six-cylinder turbocharged diesel engine with 48V mild hybrid technology, nine-speed automatic transmission, permanent all-wheel drive and active air suspension for a list price of $189,100.

This pricing is higher than comparative entry-level grades offered by the two marques which dominate sales leadership in this segment, comprising the BMW X7 xDrive40d M Sport ($179,500) and Lexus LX500d AWD ($158,700).

The GLS450d’s standard features include 22-inch AMG alloy wheels with Continental 325/40 R22 tyres and a collapsible spare, ‘AMG Line’ body styling enhancements, aluminium-look illuminated side-steps with non-slip rubber studs, multi-beam LED headlights and more.

Step inside the keyless interior and you’ll find ‘Hey Mercedes’ voice activation, fingerprint scanner (which memorises individual comfort settings for up to seven users), panoramic sunroof, heat-insulating dark-tinted rear privacy glass and the ‘Premium Plus Package’ that includes heating/cooling for the front seats, heated rear seats, head-up display, separate front/rear climate control zones, heated cupholders and more.

There’s also a concert hall-like Burmester surround sound system controlled by a central touchscreen with digital radio and Apple CarPlay and Android Auto connectivity, plus wireless phone charging, multifunction Nappa leather sports steering wheel and USB ports front and rear.

Driver assistance includes the ‘Parking Package’ (360-degree camera, active parking assist and transparent bonnet), ‘Mirror Package’ (auto-dipping rear-view mirror and electric folding door mirrors with puddle lamp projection of the brand logo) and ‘Driver Assistance Package’ (blind-spot assist, exit warning, speed sign recognition, lane keeping etc) all included as standard equipment.

Of course, Mercedes-Benz offers numerous extra-cost options including a 3500kg towing package plus interior, exterior, suspension and wheel enhancements (including Nappa leather trim) for those who want their GLS with the lot, which can easily push the list price beyond $200K.

The 4.4-litre twin-turbo petrol V8 is a perfect match for the Range Rover Autobiography.

There’s enormous power at 390kW and a colossal 750Nm of torque, but it’s delivered so smoothly and without sounding like Armageddon is beginning.

You might here the engine referred to as the P530. That signifies it’s petrol and makes about 530 horsepower. 

All that grunt means that despite weighing more than 2.7 tonnes, this SUV can hurl itself from a stand still to 100km/h in 4.8 seconds. 

An eight-speed automatic sends the drive to all four wheels. And making this SUV incredibly capable off-road is an excellent four-wheel drive system with a low range gear, plus a maximum ground clearance (thanks to the adjustable air suspension) of 283mm and a wading depth of up to 900mm.

There is a six-cylinder diesel, but if you decide on that instead of the V8 then it's all over between you and me. That’s how good this V8 is.

The GLS450d comes standard with a 3.0-litre turbocharged inline six-cylinder diesel producing 270kW of power at 4000rpm and 750Nm of torque between 1350-2800rpm.

This is paired with a 48V mild-hybrid system comprising a 48-volt battery (charged by regenerative braking) and an integrated starter-generator which provides both seamless engine stop-start and up to 15kW/200Nm of extra power and torque during acceleration.

A nine-speed torque converter automatic provides the choice of manual shifting using the steering wheel-mounted paddles, along with several selectable drive modes.

The active all-wheel-drive system continuously adjusts the engine’s torque delivery between front and rear axles (and individual wheels as needed) to maintain optimum traction and handling.

Now, you’re going to use a lot of fuel. But that’s okay because this will probably be your last petrol car and the next one will be electric so let’s go out with a bang - last drinks at the petrol bar! Land Rover says you’ll use 11.8L/100km.

After a week of punishing my Range Rover with school drop offs, shopping centre car parks, hilly suburbs, motorways and rural roads the petrol pump told me we’d used 19.8L/100km.

I’m not shocked by that consumption. This is a 2.7 tonne all-wheel drive twin-turbo V8 SUV that was almost always ferrying around four people with a pram, garden supplies and shopping in bumper to bumper traffic. A real world fuel test. 

There is that six-cylinder diesel and a hybrid version of the Range Rover, but this V8 engine suits the character of the SUV perfectly - anything else and it’s like eating reduced fat ice cream.

Mercedes-Benz claims official combined consumption of 7.8L/100km and the dash display was showing 9.0 when we stopped to refuel at the completion of our 368km test, which included the usual mix of suburban, city and highway driving with up to five passengers at times and light luggage.

Our own figure, calculated from fuel bowser and tripmeter readings, was close at 9.5 which is outstanding sub-10L/100km economy for such a substantial vehicle in mostly metropolitan use. Therefore, based on our own consumption figure, you could expect a real-world driving range of around 950km from its 90-litre diesel tank.

Driving the V8-powered, long-wheelbase, 2.7-tonne, Range Rover Autobiography is a lot easier than it sounds. Really, it’s the Range Rover’s height above sea level which will strike you first.

You’ll lord it over other cars. The length doesn’t come into it - even for parking because the visibility is so good, the steering is so light and the engine is civilised and smooth.  

This is truly an easy and enjoyable SUV to drive, with power and performance whenever you need it. 

There are several drive modes from a 'Dynamic' sporty one, which makes the engine more responsive and suspension firmer, to off-road settings.

Most of the time I left the Range Rover in 'Comfort' mode for the softest ride, but with 530 horsepower lurking in the background ready to jump out and eat up hills and overtaking.

The front seats are wide, comfortable and supportive even after hours of driving. 

It’s an enjoyable vehicle to drive, with multiple power adjustments for the seat and steering wheel combined with a large left footrest which provide supreme driver comfort and support.

The powerful and responsive turbocharged six-cylinder diesel and nine-speed auto are well suited to this application. The engine’s ample torque provides spirited acceleration from standing starts, taking only six seconds to reach triple-digit speeds.

This drivetrain would be well suited to heavy towing duties, given the 48V mild-hybrid system can contribute an extra 200Nm (in addition to the engine’s 750Nm), which raises the total theoretical torque output to almost 1000Nm.

The active air suspension provides a wonderfully cushioned ride that floats over bumpy roads, while maintaining excellent handling response and surprising agility. These commendable chassis dynamics, combined with the powerful and responsive drivetrain, makes the vehicle feel smaller and lighter than its dimensions and kerb weight would suggest.

Overall, it’s difficult to fault from a driver’s perspective, with the only exception being the voice activation function. This is often triggered by words or phrases other than ‘Hey Mercedes’ resulting in regular interruption of conversations. This needs some fine tuning.

The GLS does not have an ANCAP rating as it’s yet to be tested, but comes standard with a suite of passive and active safety features including nine airbags, auto emergency braking (AEB) with pedestrian detection and junction assist, blind-spot monitoring, traffic sign recognition, head-up display, rear cross-traffic alert, lane-keeping, adaptive cruise control with ‘distance assist’ (autonomously brakes/accelerates in heavy traffic), front/rear parking sensors, 360-degree camera and more.

There’s also two ISOFIX and three top-tether child seat anchorages in the second row, plus two more of each in the third.

The warranty is good with five-years and unlimited kilometre coverage.

There’s also five years roadside assistance and a complimentary five-year/130,000km service plan.

Yep, that's complimentary, as in free servicing for five years. I didn’t believe it myself and called Land Rover to check and was told that it does indeed mean free-of-charge.

The GLS comes with a five-years/unlimited km warranty (better than BMW and Lexus) and five years of roadside assistance. Scheduled servicing is every 12 months/25,000km whichever occurs first.

Mercedes-Benz offers capped-price pre-paid servicing packages with three, four or five-year terms. For example, the total upfront cost of the minimum three-year term is $4090, or an average of $1363 per service.
