Mercedes-Benz G63 vs Mitsubishi Eclipse Cross

What's the difference?

The Mercedes-AMG G 63 isn't for shrinking violets. It's bold, fast, and loud, and in second-generation form massively improved dynamically and technically. It's a lot of money, but there's a lot to love, and here's hoping it stays around for decades to come.

The Mitsubishi Eclipse Cross Plug-in Hybrid EV is an interesting inclusion for the brand, especially as it is typically considered a ‘value player’ in the market.

But with negligible real-world fuel consumption benefits if you drive beyond the limited EV range and a high price premium over the non-PHEV models, it’s important you see if the sums add up for your particular needs.

Primarily going to use the car for running around town? Cool. Think the 50-ish-kay EV range will work for you and make you happy? Amazing. Sold on the look of the car? Hat tipped.

But let me say this - if you are considering the Eclipse Cross PHEV, there are some alternatives you should also have on your list, including the MG HS PHEV, the Hyundai Ioniq PHEV, Kia Niro PHEV, and - the one I’d buy - a Toyota RAV4 Hybrid. For me, plug-in hybrid tech is a bit of a halfway house, in most instances offering too high a price premium for the range you’re getting to drive electric. Heck, a Kona Electric isn’t much more than the top-spec Exceed PHEV, and I’d have that if I wanted a real day-to-day EV experience.

The original (W460) G-Glass, then known as the G-Wagen (or Geländewagen for cross-country vehicle), was launched in 1979 as an ultra-capable off-roader, soon favoured by armies the world over. Arriving here in 1982, its distinctive, slab-sided form remained unchanged over the best part of four decades.

At close to 4.8m nose-to-tail, more than 1.8m across, and a bit over 1.9m tall, the G 63 is now longer (+110mm), wider (+106mm), and fractionally lower overall (-13mm), but still pulls off a convincing impersonation of a bread box.

Merc-AMG confidently quotes a drag coefficient (Cd) of 0.55 for the G 63, which isn't as bad as a brick (around 2.0… I Googled it) although it is in the same league as a heavy truck.

But it's the car's unique, upright stance, complete with pumped wheelarches and old-school flat glass, that sets it apart and draws people in. Looking more like a take-no-prisoners, functional device than a luxury cruiser, I can assure you it attracts as many admiring looks and comments as a low-flying supercar wedge.

The new-gen G 63 features AMG's vertically slatted 'Panamericana' grille, and our test example was fitted with the optional 'Night Package' ($5900) adding a range of dark exterior details including tinted indicator lenses, dark tinted glass, black exterior mirror shells and spare wheel ring, other black trim pieces and painted areas, as well as 22-inch AMG forged alloy rims.

Also worth noting, Merc has retained the G-Class's solid metal door handles, complete with the mechanism's unmistakable 'click-clack' opening and closing sound. Nice touch.

Inside, the biggest change is the upgrade from a conventional dual-gauge instrument cluster and central media stack to a pair of 12.3-inch digital screens, forming a sleek widescreen display, and bringing the G 63 in line with other recent Merc offerings.

Similarly, the gearshift moves from a traditional console-mounted set-up to Merc's 'Direct Select' lever on the steering column (exactly where the indicator stalk is located in 90 per cent of right-hand drive cars).  And the standard flat-bottom, leather-trimmed 'AMG Performance' steering wheel is a racy addition.

Like the exterior door handles, another tip of the hat to the car's heritage is retention of the horizontal grab handle ahead of the front passenger on the dash above the glove box. Nice to have something to hold on to if the going gets rough.

You’re going to be able to tell the PHEV model from its more conventional counterparts by those oversized ‘Plug-in Hybrid EV’ badges on the front doors, and if you want to tell those behind you what you’re driving, there’s also a ‘PHEV’ badge there, too. Wait, wasn’t the plan to do away with the term ‘PHEV’, Mitsubishi? 

But aside from that, the outside features just the different 18-inch alloy wheels (which are the same on all PHEV models, no matter the cost - I think that’s a bit lame, because if I’m spending $7500 on the Exceed I’d like a different wheel design!). Oh, and the Aspire and Exceed get that different lower front splitter, too.

Plus the PHEV has two fuel filler doors - one on each side of the car over the rear wheels. The driver’s side one is the EV charging ports (x2 - detailed below), and the passenger’s side one is for the petrol. Note: while the EV port is push-openable, the petrol cap still requires you to lift a lever in the driver’s footwell. 

It may be categorised a small SUV but at 4545mm long, riding on a 2670mm wheelbase, 1805mm wide and 1685mm tall, it’s big for its boots. The popular Mazda CX-5 is only 5mm longer, and it plays in the midsize SUV segment!

Inside there are some design differences, with a specific gear joystick-style selector, and a different instrument panel.

It is impressive how the brand has managed to shoehorn a petrol engine, two electric motors, a battery pack and more into the car, but there are some practicality implications. Read about them in the next section.

The G-Class has never been a particularly squeezy proposition for passengers or cargo, but an extra 40mm in the wheelbase adds even more breathing space.

Getting in is the first step, and it's a big one. At 183cm tall, in an athletic mood, I could grab the A-pillar and swing up into the driver's seat in one vaguely respectable movement.

But, those side steps aren't just for show, and at the end of a long day provide a handy staging camp between terra firma and the lofty pilot's chair.

Once on-board there's plenty of room up front, with adequate storage including a bin between the seats (now with a double door opening rather than a single hinged lid), a modest glove box, oddments space and two cupholders in the centre console, and bins with space for bottles in the doors.

There's a 12-volt power outlet in the front, second row and cargo area, while there are two USB ports in the centre console bin and a charging USB port in the second row.

In the back I could have donned a dusty Akubra and still had headroom to spare, with generous foot room, and a substantial gap between my knees and the driver's seat (set to my position).

A fold-down armrest incorporates a pair of cupholders (as well as a through-port to the cargo space for long items) and there are map pockets on the front seat backs as well as space for bottles in the doors. Two adjustable air vents in the rear of the front centre console, and another pair in the B-pillars also provide climate-controlled air to those in the rear.

With the rear seats upright boot volume is quoted at 454 litres (VDA); enough to easily swallow our three-piece hard suitcase set (35, 68 and 105 litres) or the CarsGuide pram, or a largest-suitcase-and-pram combo.

There are tie-down shackles in each corner of the floor, usefully bright lighting, a netted storage area on the passenger side (containing five fluorescent emergency vests), and folding the 60/40 split rear seat liberates even more space.

Unfortunately, gaining access to that load space is fraught with compromise. First, the single-piece rear door hinges vertically and opens from right to left. No problem when you've nosed into a shopping centre space, but not so great when you're parking nose-to-tail on the left-hand side of the road.

That means you typically have a small space between you and the car behind to get the door open, and when it is at 90 degrees, you're blocked from unloading things onto the footpath until you've shut the door.

As well as that, the door has a full-size spare (alloy) wheel and tyre attached to it. Good because a full-size spare is welcome, and bad because it makes the already bulky door even heavier.

Those keen on towing things will be pleased to hear the G 63 is rated to haul up to 3.5 tonnes of braked trailer and 750kg unbraked.

Up front, the cabin is a pretty smart place, with nice enough materials and finishes, and a few good storage options. There’s a cubby in front of the shifter, but oddly enough it doesn’t have a wireless charger (there are 2x USB 2.0 ports above) and isn’t quite big enough for a smartphone (even the smaller ones don’t fit there all that easily), and there are cup holders between the seats, a decent covered centre console bin, and door pockets large enough for bottles.

The PHEV models get a different instrument cluster dial for EV driving readout info, but all have the old-school 4.2-inch TFT colour display that lacks the size and usability of some rivals with larger info screens - the MG HS PHEV, for instance, has a 12.3-inch digital display, which shows you a lot more info than this tiny little screen does. Heck, there’s not even a digital speedometer in there - and you only get one if you buy the Exceed model, which has a head-up display (HUD).

That’s part of the problem with the way this car’s interface operates. If you want the most detailed information you need to use the touchscreen media system, but that negates the usability of the media functions. On multiple occasions I found myself switching between Apple CarPlay phone calls and searching for that particular driving info screen I found most useful (there are about 15 screens to choose from, and plenty of them are hard to decipher).

It’s a huge disappointment for a customer who might want to see all that detailed information but also listen to a podcast, answer a call, follow their phone’s mapping or just have anything other than the hybrid info come up on the infotainment screen. The screen itself - an 8.0-inch unit, with sat nav integrated into the top spec only - is fine, but small compared to today’s rivals.

In the back seat, there’s a compromise for cabin space. The leg room is good, but the seat has been bumped up to accommodate some of the electrical hardware and the petrol tank, meaning someone my size (182cm/6’0”) will find they’ve got enough room for their legs but not their head, and those even larger will really need to take care getting in and out. While pre-facelift examples of this car had a clever sliding second row seat, that’s gone. It was never a feature in any PHEV version, and undoubtedly the layout of the battery pack has something to do with that. 

The double pane sunroof no doubt eats into the space in the rear to a degree as well, and in the Exceed it likely feels a bit more cramped because of the black headliner. 

While three adults could potentially fit across the back row for very short trips, there are dual ISOFIX and three top-tether points for child seats. The Exceed is the one you want if you’re aiming to treat your rear-seat passengers right: it has heated rear outboard seats, rear directional air vents and two USB ports for charging - the ES and Aspire miss out on all that stuff.  

Boot space is 359L (VDA) for PHEV models, which is a step down from the 405 litres (VDA) for the non-hybrid models. There is extra hardware under the floor, and you don’t get a spare wheel in the PHEV models either - instead there’s a tyre repair kit. For context, we only just managed to fit all three CarsGuide hard suitcases (124L, 95L and 36L) in the boot of the PHEV version, while it was far less of an issue in the non-PHEV.

Oddly, no model comes with a power tailgate. 

The 2022 Eclipse Cross PHEV line-up is expensive compared to the petrol-turbo models.

The ES AWD has a list price (all prices MSRP, before on-road costs) of $46,490, while the mid-spec Aspire costs $49,990 and the top-end Exceed lists at $53,990. 

I know they’re not like-for-like in every instance - the ES and Aspire petrol-turbo models are 2WD, not AWD, for example, and there are some specification differences, too - but the price jump from each respective non-PHEV version is $15,500 (ES), $14,250 (Aspire) and $12,500 (Exceed).

Yikes.

You’d really, really have to want the EV driving experience to justify that additional expenditure, right?

Here’s a rundown of the specifications across the three PHEV grades.

Standard for the $46,490 ES grade are 18-inch alloy wheels, LED daytime running lights, halogen headlights, keyless entry and push-button start, cloth interior trim, manual front seat adjustment, an 8.0-inch touchscreen media system with Apple CarPlay and Android auto, a reversing camera, a four speaker stereo, digital radio and a rear cargo blind.

Step up to the $49,990 Aspire and you score LED headlights and fog lights, a lower body kit, heated front seats, faux-leather and microsuede trim, auto wipers, adaptive cruise control, an eight-speaker stereo, surround view camera, front and rear parking sensors, and an array of safety equipment that we’ll cover off in the safety section.

Choosing the range-topping $53,990 Exceed model nets you leather seat trim, a heated steering wheel, a head-up display - making it the only grade with a digital speedo! - as well as sat nav, a dual pane sunroof, and a black headliner in the cabin.

The G 63's 4.0-litre (M177) all-alloy V8 is closed deck design using direct-injection and a pair of twin-scroll turbos to produce 430kW at 6000rpm and no less than 850Nm from 2500-3500rpm. That's 10kW/90Nm more than the 5.5-litre twin-turbo V8 it replaces!

To improve throttle response and optimise efficiency, the turbos are located inside the engine's 'V', improving air flow and shortening the distance from the exhaust side to the turbos, and in turn, from the turbos to the inlet side.

And the housings on the twin-scroll turbos are divided into two parallel flow channels connecting with separate ducts in the exhaust manifold, allowing fine management of the exhaust gas coming in and pressure going out. Result is more torque and even better response times.

Drive goes to all four wheels via a new 'AMG Speedshift' nine-speed, dual-clutch auto (replacing the previous seven-speed auto transmission) with paddle shifters and a multiple downshift function which will go to the lowest ratio possible as you keep squeezing the shift paddle.

The 'AMG Performance 4Matic' all wheel drive system is front/rear biased 40/60 (50/50 in the previous model), although if you want to head off-highway the G 63 still features three 100 per cent diff locks and low-range off-road gear reduction.

The plug-in hybrid version runs a non-turbocharged 2.4-litre Atkinson cycle petrol engine producing just 94kW and 199Nm.

Meagre outputs, but the petrol unit is backed by two electric motors - the front motor has outputs of 60kW/137Nm, while the rear motor produces 70kW/195Nm. It’s all controlled by a single-speed transmission.

There is no ‘combined power output’ figure, but there is a 13.8kWh lithium-ion battery pack as part of the equation as well.

The engine can power the battery pack in series hybrid driving mode, so if you want to top up the batteries before you get to a city, you can. And there is regenerative braking, of course. More on recharging in the next section.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 13.1L/100km, with the 4.0-litre, twin-turbo V8 emitting 299g/km of CO2 in the process.

Despite the fact cylinder management tech means the engine will run on four cylinders under light load, and start-stop (with 'glide mode') is standard, we managed 16.7L/100km (measured at the bowser) over a mix of city, suburban and freeway running. To be expected for such a big bus, especially one that constantly tempts you into squeezing the throttle just to hear the exhaust bellow.

Minimum fuel requirement is 98 RON premium unleaded, and you'll need 100 litres of it to fill the tank.

The Eclipse Cross PHEV has an official combined cycle fuel consumption figure of 1.9L/100km. That’s astounding, really, but you need to realise that the test calculation is only for the first 100 kays - there’s a really good chance your real-world consumption will be a lot higher, as you can only deplete the battery charge once before calling on the engine (and your petrol tank) to juice it back up.

Electric driving range is stated at 55km based on NEDC cycle testing, while the WLTP rating is a more realistic 45km. In our testing we fell between the two during our “fully charged” 100km run, in which the electric charge initially ran for 50km. But, over the 100km run, the dashboard info screen said the car used “82 per cent” electric driving, while somehow also showing 3.9L/100km for petrol consumption.

I did the numbers at the fuel filler, and the actual return was 4.5L/100km. That’s okay, but not nearly as spectacular as you might hope, and I’ve seen very close in a RAV4 hybrid - which in most instances is cheaper than the Eclipse Cross despite being bigger and, frankly, a lot better.

I also ran the car for a further 100 kays without plugging in, just to see what the ‘worst case scenario’ might be - and it wasn’t too bad, with the fuel consumption jumping to a real-world return of 5.5L/100km. But again, that’s worse than you’ll likely get with a RAV4…

When it comes to charging/recharging, there is available AC charging using a Type 2 plug that can fully recharge the battery in as little as 3.5 hours, according to the brand. DC fast charging with a CHAdeMO plug should fill from zero to 80 per cent in 25 minutes. Maximum charge input is 3.6kW.

Like me, you’ll want to do the maths to see what is going to be the most economical way to run your car - aside from just plugging it in at the office and hoping nobody notices.

A standard 10-amp household plug - which should take about seven hours to replenish the batteries - could cost as little as $1.88 to get back your circa-50km EV range - that’s based on overnight charging, off-peak, on an average 13.6c/kWh electricity price. Of course, if you’re considering a PHEV, you might have a solar array and the electricity could well be free. Good for you.

But remember, there’s more to it than just the electricity costs - you need to also consider the additional purchase budget required just to get into the PHEV model over a regular Eclipse Cross. 

Let's cut to the chase. The G 63's pure grunt overpowers its challenging aero profile to thrust this boom box on wheels from 0-100km/h in a claimed 4.5 seconds. And believe it or not, despite its greater length and width, it has enough power to punch a 240km/h hole in the air (maximum velocity is limited to 220km/h if you choose not to opt for the 'AMG Driver's Package').

The new electronic architecture brings with it the latest version of Merc's 'Dynamic Select' system with five driving modes adjusting the engine, transmission, suspension, steering and assistance systems right up to maximum attack Sport+ mode.

All 850Nm of peak torque is available between 2500-3500rpm and pinning the throttle anywhere in that band feels like lining up a runway and preparing to rotate for take-off.

The two-stage exhaust flap arrangement allows you to turn the noise up from growl to roar even at modest around town speeds, and the nine-speed transmission is sharp and positive, with the multiple downshift function (in manual mode) hilariously good fun.

The racy AMG sports seats are as grippy as they are comfortable, and the fat 295/40 Goodyear Eagle F1 rubber, wrapped around the optional 22-inch forged alloys, does a good job of keeping all that mass and momentum in control as the high riding G 63 careens around corners.

And speaking of mass, the job of hauling it from warp speed to rest sits with big ventilated discs all around (cross-drilled 400mm front/370mm rear), clamped by monster six piston calipers at the front and single piston at the back. They're progressive and reassuringly powerful.

So, the performance is as dramatic as ever, but when I think of previous Merc-AMG G-Class offerings, two main shortcomings come to mind... steering and ride.

The steering was like a laggy mouse, with a few beats separating input at the wheel from response at the front treads. And the damping came up short, with a bouncy ride par for the course.

Still sitting on a ladder-type frame, the new G's suspension was developed by Mercedes-Benz and Mercedes-AMG. And finally, it has a decent double-wishbone independent front-end, with a rigid axle at the rear and coil springs all around. Plus, a strut tower brace, Merc-AMG calls it a 'suspension bridge', now connects the front strut towers, increasing torsional rigidity.

Ride comfort, especially in the most compliant 'Ride Control' suspension setting and riding on the big 22s, is massively better. It's no limo. You'll still feel jittering over higher frequency imperfections. But it's way, way ahead of the first-gen version.

The steering system changes from a recirculating ball to rack and pinion, and is now variable ratio with electro-mechanical rather than purely hydraulic assistance. And it's also much improved. We're not talking about a Lotus Elise-style connection with the road, but the steering is clearly more predictable and responsive.

One thing that hasn't changed is an ocean liner-worthy, 13.6m turning circle. You'll need to plan ahead for U-turns and reverse parks, but enough parking cameras (including surround view) to please Cecil B DeMille are on hand to help.

It's like a whole new world with a familiar cover wrapped around a markedly improved package. But (there must be a but) visibility is still compromised by thick window and door pillars, and despite the new dash layout ergonomic efficiency is patchy, with some switches and knobs located in relatively awkward positions.

As mentioned earlier the G 63 features three 100 per cent diff locks and low-range off-road gear reduction. But forget breakover angles and wading depths. This 4x4 seeing off-road action is as likely as an Abbott 2.0 prime ministership.

Suffice it to say, this car wears the 'Schöckl' badge at the base of its B-pillar. And in case you were wondering, Schöckl is a 1445m mountain in Graz, the Austrian city where the G-Class is built (and big Arnie Schwarzenegger was born!).

In the second-gen G-Class's development, prototypes covered roughly 2000km over a five kay trail including gradients of up to 60 per cent and lateral inclines up to 40 per cent. So, despite its irrelevance, the off-highway box is ticked.

If you’re after that electric car thrill of near-silent, almost mind-blowing acceleration, the Eclipse Cross mightn’t be the right car for you

But if swift progress and the buzz you get from taking off from the traffic lights without any hesitation at all is more your thing, it could be great for you. And if you’re not quite ready to go “full EV”, then it’s probably something you’re considering.

The EV driving mode is the best driving mode in this car. You can run it just on the petrol engine to ensure you save your battery range, and you might choose to do that when you’re driving on the freeway and know you’re approaching an urban area where the EV goodness will be better used. Or you could have it so it's using battery and petrol power, and that’s where you’ll get maximum combined performance.

But running the car in the default, EV-prioritised mode means you will make the best of this powertrain's strengths, because - for the fifty odd kays you’ll get out of the battery - it’s pretty good.

It’s also impressive the way this powertrain dips between petrol engine, battery pack or both at higher speeds. When the battery range had depleted on my test drive, the engine kicked in almost imperceptibly, working to power the car and also generate more electricity for the battery pack. It then dipped out of petrol, back to battery, and so on and so forth, multiple times during my drive. 

The best thing about the way it did so was that it was smooth. There is barely any vibration from the petrol engine, the transmission doesn’t have any gears to fumble with, and overall the refinement is really good.

There are drive modes - Eco, Normal, Snow, Gravel and Tarmac - and in my test I kept to Normal. I did fiddle with the regenerative braking reactiveness, though, using the paddleshifters to dial up or down the aggressiveness of the energy recoup system. It doesn’t feel as aggressive as some pure electric cars, but thankfully it has a decent pedal feel and progression when you apply the brakes yourself. 

The steering is light and lacks feel, and doesn’t offer that much engagement or involvement. That might matter to you if you’re like me. I wish it was more fun. But at least it’s easy to park.

While the suspension is fine and comfortable on the highway, it can feel wooden and the ride is quite lumpy at low speeds. It never really feels all that well resolved for urban driving, which is a bit of a downer considering that’s likely where a car like this will spend most of its time

The tune of the suspension - being a bit firm at lower pace - surprisingly doesn’t have any payoff when it comes to cornering, as it lacks a bit of body control, shifting its weight side to side. 

All in all it is a decent plug-in hybrid offering – and will be perfectly suitable to someone who wants some EV driving as a part of their lifestyle. It’s just a matter of doing the maths as to whether it will work for you.

All Mitsubishi Eclipse Cross models have been awarded a five-star ANCAP crash test safety rating based on 2017 testing for the pre-facelift model. 

The range has increasing levels of safety technology the more you spend, but all variants have forward autonomous emergency braking (AEB) with forward collision warning (operates between 5km/h and 80km/h) and the AEB includes pedestrian detection (between 15km/h and 140km/h). 

Standard on all grades is a reversing camera, rear parking sensors, seven airbags (dual front, driver’s knee, front side, side curtain for both rows), active Yaw control, stability control, and anti-lock brakes (ABS) with brake force distribution. Lane departure warning is standard too.

Spend up on the Aspire for adaptive cruise control, blind-spot monitoring, rear cross-traffic alert, and front parking sensors. From Aspire up to Exceed, there’s the addition of the brand’s Ultrasonic Misacceleration Mitigation System, which can dull throttle response to prevent potential low speed collisions.

No speed sign recognition is available, and therefore no smart cruise control either. Plus there is no lane centring system fitted either, and nor is there a driver attention monitoring system, so it’s falling behind on the tech front.

The Mitsubishi Eclipse Cross is built in Japan.

Mercedes-Benz (and by extension Mercedes-AMG) offers a three-year/unlimited km warranty with 24 hour 'Road Care' emergency roadside assistance provide for three years.

Servicing is recommended every 12 months/20,000km and a capped price servicing plan is available at Silver and Platinum levels for up to five years/100,000km.

There’s a huge 10 year/200,000 kilometre warranty on offer - but it’s valid if you maintain your car with Mitsubishi’s dedicated dealer service network over the 10 years/200,000km timeline, or else you get a five-year/100,000km plan.

But while the rest of the car will be covered by that decade-long warranty if you service it with Mitsubishi, the battery is only covered for eight years/160,000km, no matter where you have the car serviced.

Maintenance is due every 12 months/15,000km. But just a note - the more complex powertrain means higher service costs than the regular turbo-petrol versions. The annual fees are: $299, $399, $299, $399, $299, $799, $299, $799, $399, $799; so an average cost of $339 for the first five years, or $558.90 per visit over 10 years/150,000kn. 

Included for customers who service their car with the brand is four years of roadside assist.
