Mahindra XUV700 vs Mercedes-Benz G63

What's the difference?

The Mahindra XUV700 is a solid, well-rounded family SUV. It has a practical cabin with a usable third row and a punchy turbocharged powertrain. The Indian manufacturer needs to address a few things like interior quality and some ADAS calibration and there’s more work to do when it comes to ride and handling. But overall this seven-seat SUV represents exceptional value for money against some pricier rivals and should be on more consideration lists.

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 XUV700 is a reasonably handsome vehicle in the metal. It has a distinctive look that ensures it is immediately identifiable as a Mahindra. It is a clear evolution of the XUV500 it replaces, but far more coherent. 

It has a typical SUV shape but in profile the bonnet looks short and it has a big glasshouse with a kicked-up window line from the C-pillar back.

Front on the unique headlights surround an appealing six-bar grille with the cool Mahindra badge front and centre.

The rear features stretched and pinched tail-lights and the XUV700 sits up high on the road.

Inside the cabin is neat and the dash has an uncomplicated layout. It’s not the world’s most visually appealing interior but it doesn’t get anything wrong. Although the steering wheel feels a bit cheap.

The lovely dark grey interior is broken up with a light grey upper half and there’s stitching on the seats, dash and steering wheel. There are plenty of piano black inserts but it's not overdone. 

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.

The Mahindra boasts a versatile, practical cabin - not something all mid-size seven-seat SUVs can claim.

This grade has electric ‘smart’ door handles that pop out when the car is unlocked. They’re not super easy to grab and feel a little gimmicky. 

The sunroof has a solid power-operated blind, unlike an increasing number of models that come with a flimsy sheer blind or no blind at all, which is unimaginable in our hot Australian climate. Thank you, Mahindra! 

Another cool feature is the extendable sun-visors that are great at blocking out sun at the front or side, especially on longer drives.

A chunky rear centre headrest impedes rear visibility, but it is easily removed. However the rear outboard headrests are also big and that impacts vision out the large rear side windows.

Great to see Mahindra has retained physical controls for the air conditioning, although if you want to adjust anything digitally, you can via the central screen.

Sitting under that and the air vents are buttons for the reversing camera, hazard lights and other controls, then there’s a wireless phone charger, an extra little slot for your phone and two USB-A ports. No USB-C up front in the XUV700.

There’s decent storage up front with two compact, squarish cupholders in the console, a small central bin with a handy rubber key holder, while the glove box is a decent size and will fit more than just the manual.

Bottle storage in the front doors is excellent. The tall CarsGuide bottle fits easily and there’s extra storage for a bunch of other items. 

The front seats are on the firm side but the side bolstering is good, helping you feel nicely secured. The base makes you feel like you’re sitting on the car rather than in it. There’s not a great deal of adjustability - you can’t extend the under-thigh cushion - but the Mahindra has Mercedes-Benz-style controls on the door.

The multimedia screen houses a lot of functions. If you tap the bottom of the screen the climate controls including seat heating pop up. There are more functions if you tap the top of the screen like sound, camera view and the like.

The multimedia screen homepage has tiles, one says ‘Fun in XUV700’ (for Android Auto, Apple CarPlay and radio) and the other says ‘Fun with XUV700’ (vehicle performance). 

Driver assist functions are accessible via the driver’s instrument display using the steering wheel-mounted controls and you can change the intensity of cruise control and lane keep assist or turn off functions like traffic sign recognition and smart pilot assist. 

There are a few cons up front. The indicator sound is awful and makes it feel cheap. There are some quality issues, like the flimsy panel to the lower right of the steering wheel that’s home to the auto stop-start. It feels like it’s going to fall off. And some of the fabrics don’t quite line up.

The device charger could do with a fan as my phone gets super hot charging on the pad, while the ‘Siri’ talk-to-text function of Apple CarPlay is patchy. 

In the second row, the legroom is decent and while there’s not acres of room I don’t feel cramped sitting behind my 183cm (six-foot) driving position. A tiny transmission tunnel means good centre seat legroom. There’s a lever on the front passenger seat back allowing rear passenger behind to move that seat forward.

Headroom is also decent without being ample. There’s about an inch between my head and the roofliner.

The window line is low enough for small children to see out but not so low you feel like you’re sitting on the car. 

The rear seating row is comfortable enough but the backrests - which recline - are flat. 

You’ll find rear knee-level air vents, one USB-C port (the only ‘C’ port in the car) and a pair of map pockets, a phone slot under the vents, a centre armrest with two cupholders and loads of door storage for big bottles and more.

For child seats, the two outboard seats have ISOFIX anchors and there are two top tethers as well.

Access to the third row is much easier than I expected for a mid-size seven seater. The passenger-side single outboard seat tumbles flat then up, leaving plenty of space to get into the rear. There’s even a grab handle to assist.

Headroom isn’t great back there for me, but again, I am six-foot tall. A kid will be fine. There’s a surprising amount of legroom and toeroom. 

Third-row occupants have access to cupholders and air vents on both sides, a fan speed dial, speakers and a 12-volt outlet that is also accessible from the boot when the seats are lowered.

The fact the curtain airbags cover the third row is a big tick. Overall, a solid third-row experience.

There’s a handy plastic lever on the rear of the seats to lower and raise the third row easily. They don’t quite fold flat into the boot floor so they sit up a little, but don’t intrude on boot space.

It looks like there is a cargo cover option but it wasn’t fitted to this example of the car. There are lots of hooks in the boot to hold bags, but note there is no power tailgate - it’s a manual operation in the Mahindra. 

You also get a temporary spare wheel housed externally on the underside of the car.

One thing I can’t tell you unfortunately is the boot volume. Mahindra doesn’t provide those figures. I can say that when all three rows are in place, there is not much room behind the third row. Just enough for three backpacks or a few bags of shopping in a row. When the third row is lowered, there’s ample luggage space.

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.

Okay, you're laying down a quarter of a million bucks ($247,329 before on-road costs) and it's fair to expect some serious tech and standard equipment to keep you feeling warm and fuzzy after you're finished impressing friends and family with the G 63's howling acceleration.

For a start, there's a bunch of leading-edge safety tech on-board (detailed in the safety section below), and as expected that substantial cost-of-entry brings an extensive list of luxury features.

We've touched on the twin 12.3-inch 'Widescreen Cockpit', and available media includes digital radio and TV tuner, internet connectivity and 3D nav (with dynamic route guidance), as well as smartphone integration with Apple CarPlay and Android Auto.

Audio is a thumping 15-speaker, and 590-watt Burmester surround sound system, and the ambient lighting set-up offers a choice of 64 colours.

Also included are 'Multibeam' LED headlights, 'AMG Ride Control' adaptive damping, a 'Parking Package' with 'Active Parking Assist' and 360 camera, a sliding glass sunroof (with tilt function), the selectable AMG sports exhaust system, keyless entry and start, the AMG Performance steering wheel (trimmed in nappa leather), and 21-inch AMG '5-Twin spoke' alloy wheels.

Then there are the three 100 per cent differential locks (plus an 'off-road information centre'), electronically adjustable front seats (ventilated front and heated front and outer rear), steering column and mirrors (with memory function), three-zone climate control, nappa leather upholstery, a leather-finished dashboard with open-pore ash wood trim, a 'Dinamica' microfibre roof liner, and an AMG-specific IWC design analogue clock. Plus, the 'Dynamic Select' system enables a choice of pre-set driving profiles or individual settings.

The optional 'Exclusive Interior Plus Package' ($10,300) fitted to 'our' car adds deluxe nappa hide on the dashboard, door centre panels and grab handle, as well as a diamond quilted treatment on the seat centres, a black 'Dinamica' roof liner, velour floor mats (with edging in nappa leather), a frameless interior mirror and air vents in 'Silvershadow'.

On top of that the test vehicle was optioned with the 'Night Package' ($5900) detailed in the Design section, and Designo 'diamond white bright' paint ($5900) for a manufacturer's recommended list price (MRLP) of $269,429.

That puts the G 63 in the same price and equipment ballpark as the supercharged V8 Range Rover Autobiography ($268,900), twin-turbo V8 Porsche Cayenne Turbo ($239,400), and its Mercedes-AMG GLS 63 sibling ($221,729), powered by a version of the 5.5-litre twin-turbo V8 used in the first-gen G 63.

An impressive trio of alternatives, but in reality the idiosyncratic G 63 doesn't have any direct competitors, and for those who give in to the pull of its powerful tractor beams value-for-money becomes a uniquely personal concept.

The XUV700 is powered by what Mahindra calls its ‘mStallion’ 2.0-litre, four-cylinder, turbo-petrol engine delivering 149kW of power and 380Nm of torque. These are solid outputs and the only petrol-powered mainstream rivals that come close to those figures are the Kia Sportage/Hyundai Tucson mechanical twins, with their 1.6-litre turbo punching out 169kW/350Nm.

The Mahindra’s engine is paired with a six-speed automatic transmission driving the front wheels only, so no all-wheel-drive option here.

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 XUV700 is only available with that petrol engine so no fuel-saving hybrid or plug-in hybrid options for now.

It’s also on the thirsty side with an official combined (urban/extra-urban) cycle fuel use figure of 8.3 litres per 100 kilometres. That’s more than petrol versions of the Mitsubishi Outlander and Nissan X-Trail.

After a week of mixed but mostly urban driving, the trip computer showed an average of 8.5L/100km, but my own calculation based on real-world use at the fuel pump came out at 11L, so a bit of a discrepancy there.

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.

On the road the Mahindra has some clear pros and cons. Overall, it’s a more polished performer than you might expect.

The turbocharged engine sounds good when pushed and is a punchy unit, delivering linear acceleration and getting to speed quickly, mostly without fuss. The 235/60R18 MRF Wanderer tyres have a tendency to chirp when accelerating hard and the XUV700 would benefit from higher quality rubber.

The six-speed auto transmission works well with the engine, delivering smooth shifts but it can hold gears on downhill runs.

Ride quality is a mixed bag. Those tyres have a high sidewall but you’ll feel bumps like road and bridge joins, while speed bumps aren't so smooth, either. The ride is on the firmer side but it’s no dealbreaker. 

It’s a little top-heavy when cornering, so there is lateral movement in the car. A good reminder this is a family SUV, not a hot hatch.

Steering is overly light and a bit too sharp for this sort of vehicle. There’s nothing wrong with dull or slower steering in a family car because it’s less responsive if you accidentally turn the wheel when distracted by shenanigans in the back seat.

The brakes are also quite sensitive. Just a tap of the foot and you’re coming to a full stop.

A bit of road and wind noise creeps into the cabin, so it’s not the most hushed interior, but it’s not too dramatic.

Other points include a decent turning circle, making it more nimble than you might think in tight parking spots, and poor-quality, low-definition lane watch camera display. Also the remote lock and unlock is temperamental. You need to double check it’s locked.

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.

The second-gen G 63 hasn't been assessed by ANCAP or Euro NCAP but its new electronic architecture brings the car up to speed on active safety tech, now incorporating 'Distronic' cruise control with 'Active Distance Assist', 'Active Brake Assist', AEB (forward and reverse), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Adaptive High-Beam Assist', tyre pressure monitoring, and 'Traffic Sign Assist'. Plus, the 'Pre-Safe' system prepares the vehicle and occupants in the face of an inevitable collision.

And once that impact has occurred, you're protected by nine airbags, including rear seat airbags, full-length curtains and a driver's knee bag.

There are three top tether points for child restraints/seats across the back seat, with ISOFIX anchors in the two outer positions.

Mahindra covers the XUV700 with a seven-year or 150,000km warranty which is generous but doesn’t match Kia’s seven-year, unlimited-kilometre term. It also includes seven years of free roadside assistance.

The servicing schedule has a few quirks. There’s a free service at 1500km or one month of ownership, then the next service is at 12 months or 10,000km, whichever occurs first. After that the term is every 12 months or 15,000km, so it’s a little confusing.

There’s four years of capped-price servicing that averages out to about $445 per service. That’s roughly $100 more on average per service than a petrol Mitsubishi Outlander.

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.
