Jeep Grand Cherokee L vs Mercedes-Benz GLC300

What's the difference?

Jeep’s aim with this car is to lift the Grand Cherkee to a more premium level, and that’s about brand equity and badge credibility as much as it is the vehicle itself.

The seven-seat L has stepped up in price, but also in practicality, refinement and equipment, while maintaining serious off-road ability.

Does it have what it takes to tempt people away from, say, the German Big Three? That’s a tough ask, but this Jeep certainly has more of what it takes to make that a real possibility. 

For mine, the entry-level Night Eagle is the pick. Well equipped, heaps of safety and plenty of off-highway prowess.

The GLC300 Coupe isn't quite as great when it comes to being a family car as the regular SUV version of the GLC, and that's purely down to the sloping roofline which not only makes access more difficult to the second row but reduces boot capacity.

That said, the GLC300 Coupe makes a much better family car than a Mercedes-Benz C-Class sedan, or any sedan.

Easy and enjoyable to drive, packed with great features and still practical, the GLC300 Coupe would still cut it as a good family car.

A decade. That’s how long the previous Grand Cherokee was on sale in Australia, Which is ages, but also testament to the quality of that fourth-generation car’s design.

And there are echoes of it in this new model’s exterior. The overall proportions are similar, although the track is increased by 36mm, and the overriding impression is that key elements have been made slimmer and wider for a more contemporary look.

For example, the headlights, LED on all models, are shorter, but longer, while the signature seven-bar Jeep grille has been truncated a little and stands more upright.

Character lines along the side of the car are softer, and the rear follows the same slimline philosophy. But it’s inside where the biggest steps have been taken.

The dash layout and hardware have been transported from the relative Dark Ages to a clean and simple approach dominated by this broad centre console, topped by a sleek media screen.

The screen measures 8.4 inches in the entry-level Night Eagle, stepping up to 10.25 inches in the upper grades.

The latest, configurable, digital instrument cluster enhances the low-key tech vibe, and there’s a sensible mix of on-screen controls and physical dials and buttons. That said, there are a lot of buttons across the lower part of the centre stack and steering wheel.

The rest of the interior is a blend of simple lines and a subtle colour palette, including piano black highlights. It feels more mature and premium than the car it replaces.

Coupe SUVs aren’t for everybody… they’re not even for lots of people. But the design of an SUV with its roof cut down so that it meets the tailgate at an almost sportscar-like angle appeals to more than a few fans. The thing is they don’t just like the look, they love it, and they also probably enjoy how much the styling makes other people cranky.

To my eyes the GLC300 Coupe is the best execution of the bodystyle compared to those of BMW and Audi. There’s an elegance to the GLC300 Coupe and the AMG-line adds a tough look that only enhances the solid, powerful but pretty look.

The GLC Coupe is a mid-sized SUV and this new generation model is a bit bigger the previous one and now measures 31mm longer at 4763mm end to end, it’s 1890mm wide, 1605mm tall and has a wheelbase of 2888mm.

It’s also more aerodynamic than ever. No seriously, it’s drag coefficient is now 0.27 and it looks like a bar of soap - and it's about as slippery as one, too.

More curved surfaces await inside with a dashboard that pours down into the large centre console and it's adorned with a sloping and large portrait-style media screen. 

At night or in tunnels the ambient lighting glows through the air vents and skirts the edges of the door trims, console and dashboard.

It’s a minimalist and high-tech cockpit with modern sports seats up front and a Nappa leather wrapped steering wheel with its twin blade design.  

So, how does the coupe design work for family practicality? Let’s take a look.

When it comes to practicality, thoughtful, family-friendly touches include large door apertures, with the doors themselves opening right out to 64 degrees, as well a second row seat able to move fore and aft to balance passenger and/or cargo space. 

Up front there are big bins in the doors with space for large bottles, a pair of decent size cupholders in the centre console, a two-tiered storage box between the seats that doubles as an armrest, and a covered wireless charging bay in front of the gearshift.

For connectivity and power there are two USB-A and two USB-C ports, as well as an ‘aux in’ socket, and a 12-volt outlet.

Jump into the second row, and sitting behind the driver’s seat set for my 183cm position, I enjoyed heaps of headroom and hectares of legroom, remembering it’s possible to slide the middle seat forward to give third row passenger more room, or increase load space.

Again, there are generous pockets in the doors with space for large bottles, map pockets on the front seatbacks, a fold-down centre armrest containing two cupholders, and rear seaters have their own ventilation control.

The dual USB-A and USB-C ports are repeated in the back, and there’s a 230-volt AC socket for three-pin plugs.

Access to the third row is helped by a roll and fold function in the second row, and once back there space is generous and the amenities are civilised.

I could sit bolt upright without any head clearance issues, and legroom is good. There are bottle holders on each side, adjustable ventilation in the C-pillars, small storage pockets, and yet more USB outlets. 

And how’s this for a parent’s dream? ‘Fam Cam’ (optional on the Limited and standard on the Summit Reserve) is an adjustable rear seat monitoring camera able to switch between all second and third row positions. No more craning around and taking your eyes off the road to check what’s going on back there.

Even with all seven seats upright, boot space is 487 litres. Fold the 50/50 split third row and that grows to 1328L, and with the second (40/20/40 split) and third rows down you’ve got 2395L, enough room to start a boutique furniture moving business.

The loading height is user friendly, there are multiple tie-down hooks and a 12V outlet, there’s no lip to get over the top of, and a power tailgate, standard on all grades and hands-free on the Summit Reserve, is always welcome.

The Grand Cherokee L is rated to tow a braked trailer up to 2.8 tonnes, although that’s reduced to 2.3 tonnes in the Summit Reserve, partly due to the standard air suspension. And off-roaders rejoice, the spare is a full-size (18-inch) steel rim. 

SUVs are the most practical cars for families because of the better access to the cabin thanks to their large doors and slightly elevated ride height, their big boots with wide and tall hatch openings and their high flat rooflines. They’re essentially raised station wagons.

A coupe-style SUV still has four doors but they are less boxy due to the sloping roofline which falls away quickly to meet the tailgate at a lower point. The effect is a sporty-looking shape but practicality is lost in this exercise of form over function.

The second row doorways aren’t as large as those on the regular SUV. I did a side-by-side test and felt like I had to duck under the sloping roof when getting out of the back seat.

The smaller opening also made it trickier to lift my toddler daughter into her baby seat.

The sidesteps are also surprisingly handy for bigger kids and my eight-year-old used them every time when climbing into the car.

Cabin storage is outstanding with huge door pockets and cupholders in both rows, and while the 545-litre boot in the GLC300 Coupe is 80 litres smaller than the cargo capacity of the regular GLC SUV, it's bigger than the previous version of the Coupe.

As for people space, there’s enough headroom for me at 189cm tall in the back seat and heaps of legroom, even behind my driving position.

I’ve mentioned the lack of climate control in the second row, but also should point out that there are no USB ports back there either.

There are USB ports in the big centre console box upfront and a long cord should be able to make it to the second row. 

There’s a wireless phone charger but it's housed in the bowels of the centre console too, and you’ll need to weave your hand while clasping the phone under the shiny black trapdoor, past the cupholders possibly with drinks in them and almost under the dashboard.

Mercedes-Benz is offering Australia just the GLC300 grade in both the SUV and Coupe body styles.

High-performance AMG variants are out overseas now and will arrive in Australia soon, too.

You can expect to pay more for these AMG beasts - a lot more than the $113,900 list price of the GLC300 Coupe.

Still the GLC300 Coupe does come standard with an AMG Line body kit and 20-inch AMG alloy wheels. LED headlights are also standard, so is the panoramic glass roof, tinted rear glass, proximity unlocking and a power tailgate.

Inside there’s synthetic leather Artico upholstery, sports heated front seats, Nappa leather steering wheel, an 11.9-inch media display with Apple CarPlay and Android Auto, a 12.3-inch digital instrument cluster and a head-up display. There’s also dual-zone climate control and wireless phone charging.

The value is good in terms of features, although the price is slightly higher compared to the rivals such as the BMW X4 xDrive30i ($106,400) and Audi Q5 Sportback 55TFSI ($110,200).

It’s worth pointing out, too, that the GLC300 Coupe is about $10K more than the GLC300 SUV version. Why? The coupe versions of prestige SUVs always tend to be pricier than their regular more boxy SUV siblings. Somebody in marketing will be able to explain why.

Having lived with the GLC300 Coupe with my family over the past few days I can say the proximity unlocking which works by touching even the back door handles is excellent, the tinted windows are dark and cut out much of the sun's glare, but there’s no climate control in the second row. There are air vents back there, which is good.

I found that on hot days the semi-transparent shade on the glass roof couldn’t stop the cabin from heating up quickly.

All versions of the Grand Cherokee L are powered by a 3.6-litre naturally-aspirated V6 petrol engine producing 210kW at 6400rpm, and 344Nm at 4000rpm, driving all four wheels through an eight-speed auto transmission and a transfer case - single speed on the first two models and two-speed on the Summit Reserve flagship.

The evergreen Pentastar V6 is a naturally-aspirated, all-alloy, quad-cam design featuring dual variable valve timing and sequential-injection.  

If you want more grunt? Yes, there’s a 5.7-litre Hemi V8 available in this new Grand Cherokee. But it’s in the States, not here. There’s no diesel option, either. But as mentioned earlier, a plug-in hybrid, the 4xe (four-by-e) is coming later in 2022. 

The GLC300 Coupe has a 2.0-litre four-cylinder turbo-petrol engine making 190kW of power and 400Nm of torque.

There’s also an overboost function which allows the engine to make an extra 17kW and 200Nm just for a brief moment, but that extra dollop of grunt combined with the regular output provides impressive acceleration (0-100km/h in about 6.3 seconds) for overtaking or moving quickly when you need to.

A smooth nine-speed automatic transmission sends the drive to all-four wheels.

The GLC300 Coupe is all-wheel drive and while there’s a setting for rougher terrain, along with one for comfort, eco and sport, but I’d make sure that it doesn’t get any more adventurous than tame gravel and dirt roads.

Mercedes-Benz refers to the GLC300 Coupe as a mild hybrid and this is because it has a 48-volt system and an integrated starter-generator.

This type of hybrid doesn’t use electric motors, doesn’t drive the wheels and won’t save much fuel, but it will provide efficiencies by supporting the engine and when coasting, plus will reduce petrol consumption to a small degree.

Jeep’s official fuel economy figure for the Grand Cherokee L on the combined cycle is 10.6L/100km, the 3.6-litre V6 emitting 243g/100km of CO2 in the process.

Given the specific on and off-road combination of the launch drive we’ll wait until we can evaluate the car over a longer period to quote an ‘on test’ number.

Worth noting stop-start is standard, and in the name of weight saving, the car’s bonnet and tailgate are aluminium. Still weighs around 2.2 tonnes, though.

The tank holds 104 litres, which using the quoted consumption number, translates to a range of around 980km.

As we mentioned above the GLC300 Coupe's 48-volt mild hybrid system is not the kind of hybrid that will allow you to drive miles on electric power, nor will it dramatically reduce fuel consumption in the way a parallel, series or plug-in hybrid will. But every bit of efficiency helps.

Mercedes-Benz says the GLC300 Coupe will use 7.7L/100km after a combination of open and urban roads. 

We had the GLC300 Coupe for just two days, but in that time my family covered 176km of regular daily usage which took in motorways but mainly suburban duties such as the school run, supermarket dashes, that sort of thing.

In our fuel test we measured 14.48 litres at the fuel pump which works out to be an on-test fuel use figure of 8.2L/100km and not far off the manufacturer’s claim. 

While this fuel consumption isn’t overly high, a plug-in hybrid or even a parallel or series hybrid could return about 5.0L/100km or less.

Mercedes-Benz has dropped plug-in hybrids from its Australian range which is a shame because it would be good to see more efficient options in the GLC range. Of course if you want more efficiency from a Benz of the same size, there is always the fully electric EQB or EQC.

In driving the new Grand Cherokee the first thing you recognise is the Pentastar V6’s characteristic induction sound. That’s not to say it’s overly loud, just familiar.

But in terms of what it delivers, nearly 90 percent of the engine's peak torque is available from 1800 to 6400 rpm, so you’ve got that mid-range pulling power which is as nice on the highway as it is around town, but also good for people that are into towing.

The eight-speed auto is nice and smooth, as well, and even though it’s a conventional torque-converter unit, manual shifts through the steering wheel paddles are quick.

Suspension is multi-link front and rear, with the top-spec Summit Reserve picking up air suspension and active damping. Major components are alloy to reduce unsprung weight but you can certainly feel the scale of this car. 

It’s 5.2 metres long and weighs roughly 2.2 tonnes, so you’re guiding this sizeable machine along the road. It’s not an involving drive, we’re not in sports car territory here. But it feels stable and predictable in cornering, and body control is well buttoned-down.

The electrically-assisted steering’s weight is nice from parking speeds right up to freeway velocity, but road feel through the wheel is relatively modest.

In terms of the seating position, you do feel as though you’re sitting up and on, rather than down and in the front seats. But when it comes to support, after hours behind the wheel, including off road, the front chairs remained comfortable.

This is a big vehicle, that will often have a boat, van, or something else substantial hitched to the back of it, and the brakes are suitably specified.

Big discs are ventilated all around, clamped by two piston calipers at the front and singles at the rear, and on the off-road section of the launch drive we were by necessity leaning on the brakes for long periods of time.

You could occasionally smell that they were working hard, but the pedal remained firm all day, without a hint of fade.

Speaking of off-highway performance, as part of its development program Jeep tested this new Grand Cherokee in remote parts of Australia, with more than 60,000 km under the wheels of various prototypes. Likely a big help in setting up the local spec. 

And that spec is, four-wheel drive in all models, as well as a single-speed transfer case in the Night Eagle and Limited, with the latter also featuring the ‘Selec-Terrain’ traction management system, controlling torque split (up to 100 per cent of drive to either axle), as well as the brake calibration, steering, suspension, throttle, transmission, transfer case, traction control, stability control, and ABS settings.

The Summit Reserve boasts a two-speed transfer case, with low-range reduction, as well as traction management and air suspension with electronic adaptive damping.

The air suspension incorporates five height settings - Normal, Off-road 1 (40mm lift), Off-road 2 (60mm lift), Park (46mm lower), and when in sport, Aero (21mm lower).

In typical Jeep fashion we attacked challenging fire and forestry trails on the launch drive and a couple of things emerged.

First, on street-focused tyres this car does incredibly well off-highway. And second, the ‘Quadra-Trac II’ 4x4 system with low-range capability in the Summit Reserve, combined with the crawl control function, makes a significant difference. You find yourself feeling that bit more composed and confident tackling very rough sections.

Also in the Summit Reserve, a low-set, forward facing camera allows you to see what’s actually happening at the front wheel via the central media screen, and in the Off-road 2 setting the car feels like it’s up on stilts and able to tackle anything in its way.

And for those that really want to get amongst it, the body clearance data is below.

There’s a lot to like here but the short version is the GLC300 Coupe has a comfortable ride, but good handling, with a responsive engine, although rear visibility through the small back window is poor.

If we drill down a bit further I can tell you that excellent cameras around the car will help you check to make sure kids aren’t running around behind you and that forward and side visibility through the window is good.

An important takeaway is that the GLC300 Coupe is easy to drive with light steering and an engine that’s mild and controlled in its power delivery.

The gear shifter is mounted on the steering column, in the same way an indicator lever is. So putting the car into Drive, Reverse and Park is so easy and means you don’t have to take your hands off the steering wheel. 

As a family car I liked the good body control and composed ride. We have a small toddler that we can sometimes only get to sleep by taking her for a drive and we found that she could nod off and not be woken by potholes and speed bumps or too much leaning in the corners. 

The GLC was given the maximum five star ANCAP rating in 2022. There’s AEB, active lane keeping assistance and active blind spot warning and nine airbags including a centre airbag.

As mentioned above I especially liked the surround-view camera systems - which let you look right around the car - good for driveway safety and kids.

For child seats you’ll find two ISOFIX mounts and three top tether anchor points in the second row.

I was also impressed to see a space-saver spare wheel under the boot floor and not just a puncture repair kit. 

Jeep covers the Grand Cherokee with a five-year/100,000km warranty, which is behind the five-year unlimited kays cover which is pretty much standard in the mainstream market now.

But you do receive 12 months complimentary roadside assistance, which is renewed for another year every time you service your vehicle at an authorised Jeep dealer.

Service is recommended every 12 months or 12,000km, and capped price servicing is available for $399 annually for the first five years. Not bad for a car of this scale and complexity.

The GLC300 is covered by Mercedes-Benz's five-year, unlimited-kilometre warranty. 

Services are annually or every 25,000km. And you can buy a three-year service plan for about $3000.
