Jeep Compass vs Mercedes-Benz Gls450

What's the difference?

The Jeep Compass Trailhawk is a curious beast. On the one hand, it looks pretty cool, and it has a well-executed new interior, featuring one of the best multimedia set-ups in the business. It’s spacious and has a long list of standard comfort and safety gear.

Sadly, that’s where the positives end.

It is way too expensive for what you get, especially when you consider the quality of some of its rivals from mainstream and premium brands.

The driver assist features are badly in need of recalibration and the overall drive experience is a letdown.

If you really want a diesel-powered small SUV, perhaps look at one of the much better diesel models at the smaller end of the medium-SUV segment.

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.

When the second-gen Compass was revealed, it was seen by many as a mini Grand Cherokee. Which isn’t a bad thing. It looks tough enough, but also has a softer edge than something like the Jimny.

As part of the 2021 update, Jeep refreshed the styling with slimmer LED headlights and a new daytime running light signature, a revamped bumper and seven-slot grille, as well as a broader bonnet.

The Trailhawk features variant-specific red and black decals on the bonnet, and a unique grille treatment, as well as the visible skid plates and red tow hooks.

It certainly gives the impression of having some off-road cred, and while some will love the Trailhawk name emblazoned across the bonnet, it’s a bit much for me. The 'Galaxy Blue' premium paint looks too sparkly in direct sunlight and has an almost purple hue.

An example of wishful thinking is the green ‘Diesel’ badge with a leaf next to it on the rear of the vehicle. Save the eco badges for your electrified vehicles, Jeep.

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.

The Compass sits in the small-SUV category but its larger dimensions mean it’s almost big enough to compete with models in the medium-SUV segment.

It’s longer, taller, wider and has a longer wheelbase than other larger small SUVs like the Kia Seltos and Honda HR-V, but isn’t as big as a mid-size Mazda CX-5.

It feels larger inside than other models it shares a platform with – namely the Jeep Renegade and Fiat 500X, that are no longer sold in Australia.

The biggest change ushered in by the update is the interior. Jeep has completely overhauled the cabin to the point that it’s unrecognisable compared to the pre-facelifted model.

The new dash design is much more appealing and the layout is well executed. There’s a mixture of soft-touch materials and plastic panels with red stitching running across the fascia. It’s so much more up-to-date than the old Compass and there’s a robust yet semi-premium look to the cabin.

A new steering wheel is in keeping with Jeep’s new generation of models that includes the Grand Cherokee due in Australia this year. It’s chunky, feels nice to touch and features clear audio, phone and cruise controls.

Jeep has persisted with its quirk of housing the volume and song/station skip buttons on the rear side of the steering wheel spokes. Once you remember which side volume lives (the right), it’s easy to change the levels. But surely it would be better to house them on the front of the wheel, with labels?

Storage wise, the glove box is narrow, as is the central bin, but it’s deep. The doors will hold 600ml bottles and the console houses two decent-sized cupholders with durable rubber lining which is easy to clean and can take a beating. The cupholders are separated by an upright phone holder.

Speaking of durable, that’s clearly the theme Jeep is going for with the Compass Trailhawk interior. It comes standard with rubber mats throughout, including the boot, which is great for protecting the carpet if you fancy a bit of camping.

What isn’t durable, however, is the cheap and tacky indicator stalk that feels like it will snap off every time you touch it.

After spending some time in European cars prior to the Jeep, it’s nice to experience strong air flow from the air conditioning system, especially at the height of a Melbourne summer. It’s also great to see physical buttons for the air con controls.

You can, however, also control the climate via the latest 'Uconnect 5' multimedia system housed in the 10.1-inch touchscreen.

This system is undoubtedly one of the Compass’ strong points. The modern graphics look very cool and the main icons make sense.

Once you dive into the menu there are extensive options but it’s not overwhelming. It’s intuitive and clever. The sat-nav visuals are clear and appealing too.

It’s an excellent set-up and better than systems from a whole host of Jeep’s mainstream rivals.

Apple CarPlay set-up was easy but there is an odd lag when selecting a command on the touchscreen that isn’t there when you use the Jeep system.

Another highlight is the exceptional Alpine nine-speaker audio system that’s part of the Trailhawk Premium package. It’s a belter!

The new digital instrument cluster has clear dials but changing the screen layout is fiddly. The Compass also lacks a head-up display.

The front seats with red embossed Trailhawk across the front look good, but the cushion feels like it’s elevating you in the seat. It’s not a problem with the power adjustment, it’s just the way the cushioning is designed. Thigh support is limited but upper body bolstering is good.

Visibility is impacted by the narrow rear windscreen and the tiny rear windows behind the C-pillar, that are pointless.

Rear occupants have access to lower air vents, a USB-A and USB-C port, 230-volt AC plug and a 12-volt DC plug. There are two map pockets, rubber floor mats and 600ml bottles will just fit in the door.

Space wise, there’s plenty of leg and toe room in the rear, and just enough headroom for this six-footer to avoid scraping the headliner.

Getting in and out of the front and rear seats is easy thanks to the Compass’ ride height.

The rear seats are flat and firm and the 60/40 split-fold seats have a fold-down central armrest with two cupholders.

When you open the power tailgate, the boot doesn’t look particularly big, but at 438 litres (1251L with rear seats folded), it’s five litres more than the Kia Seltos GT-Line and eight more than the Haval Jolion.

A full-size spare wheel lives under the boot floor and the cargo area features metal tie-down hooks and a small storage tray.

The cargo blind is useful but there’s nowhere to stow it when it’s not in use. And you have to lower the rear seats when you want to put it back in place.

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.

As mentioned, the Compass Trailhawk is now the only remaining small SUV in Australia offered with a diesel engine. Well, from a mainstream brand at least. The BMW X1 is the only premium small SUV offering with a diesel donk.

The Jeep uses a 2.0-litre four-cylinder turbo-diesel delivering 125kW at 3750rpm and 350Nm at 1750rpm. It is paired with a nine-speed automatic transmission and comes with four-wheel drive as standard.

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.

Jeep’s official combined cycle fuel use figure for the Trailhawk is 6.9 litres per 100 kilometres. After a week of mixed but mostly urban driving, we recorded a much higher figure of 11.2L/100km.

The Compass has a 60-litre tank. Combined CO2 emissions are rated at 181g/km.

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.

Jeep claims the Trailhawk has some off-road ability, but we didn’t get a chance to test that. Most driving was around town, freeways and city fringe.

The first thing I noticed when I got behind the wheel was the awkward position of the accelerator pedal. It could be the wheel arch intruding into the footwell, but the right side of my right foot constantly brushed the carpeted panel. It’s annoying and a clear design flaw.

Another flaw is the idle-stop system. When you park, the idle stop kicks in and cuts the engine off. But if you want to properly turn the engine off and get out of the car, you have to do something to wake up the engine, then turn off the ignition. Another annoyance.

The diesel engine is responsive enough, but it lags on take-off and it’s not as torquey as expected. Accelerating hard doesn’t reward the driver with instant response, and momentum is blunted by steep ascents.

It does come alive around 3000rpm which seems to be a sweet spot.

The nine-speed auto can sometimes hold gears and the brakes are on the spongey side.

The Trailhawk feels like a heavy vehicle on the road. Much heavier than its 1621kg tare weight would suggest. As a result, it lumbers along and makes for sloppy handling.

It moves around the road too much and there is quite a lot of body roll in corners. It’s slow to respond coming out of corners, too.

The steering feels lazy and it’s weighted on the heavy side. It doesn’t make for an engaging steer.

Ride comfort around town is well sorted. For the most part, it absorbs speed bumps and crumby urban streets, without offering a truly comfortable ride.

Overall ride quality diminishes at higher speeds. It’s busy and jittery and never feels settled.

Needless to say, this is not the small SUV to buy for navigating city traffic or to take for a fun drive on your favourite twisty country road.

A brief section of unsealed road highlighted the excellent traction of the Trailhawk.

The 225/60 R17 Falken Wild Peak tyres produce a bit of tyre noise on coarse chip roads but otherwise the cabin is fairly well insulated from outside noise.

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 Compass comes with a five-year or 100,000km warranty and five years of free roadside assistance. Every time you service your vehicle at a Jeep dealer, another year will be added to the roadside assist program.

The servicing schedule is every year or 20,000km for a diesel Jeep, whichever comes first.

Jeep offers a capped-price servicing scheme for the first five years. The Compass Trailhawk costs $399 for each of these services.

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.
