Mahindra XUV700 vs Audi RS Q8

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 Audi RS Q8 Performance is a lot - of everything. It offers lots of power, lots of performance, lots of space and lots of luxury. But it’s also a lot of money, and at more than $250k it’s not going to be on everyone’s shopping list. It’s a very niche proposition for a small group of buyers. For those select few, those who want a lot of everything and who crave the ultimate of whatever product they’re buying, then the RS Q8 Performance is going to be a very tempting proposition - even if they never set any lap record in it.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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. 

We don’t refer to ‘facelifted’ cars for no reason, the RS Q8 Performance has a number of visual changes.

These include a new Audi ‘singleframe grille’ and new front bumper design, with a new Matt Carbon trim package available to highlight that.

There’s also a new rear bumper design as well as new digital daytime running lights at the front and digital OLED lights at the rear.

The unique forged alloy wheels are another design change, but also bring a functional element. Measuring 23 inches they do a good job of filling out the wheel arches and give the RS Q8 Performance a purposeful stance and good proportions. But they are also 5kg lighter per wheel than the 22-inch rims on the RS Q8, saving unsprung weight to help the ride and handling.

Inside, Audi hasn’t made any dramatic changes to the design, which is fine because the brand does some of the best cabins on the market in terms of look and feel.

What is new is an aluminium inlay and an optional RS interior design package which provides a unique finish to the seats, with contrasting stitching, for an additional $4100.

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.

While it’s easy to get swept up in the power and speed of the RS Q8 Performance, it’s important to remember that it’s an SUV and it needs to offer ‘utility’ as well as ‘sports’. 

With that in mind, the front seat occupants are well looked after with supportive and comfortable sports seats, with a good amount of small item storage spaces. 

The rear seats are surprisingly comfortable, despite the sloping roofline of this ‘coupe-style’ SUV. Audi has cut recesses into the ceiling to create more headroom, so it will be fine for anyone under six-foot tall. Despite there being five seat belts, this is realistically more of a four-seater for adults, although three smaller kids could squeeze across the back.

There’s also a pair of cupholders, two USB-C ports, a 12-volt outlet and your own climate controls for the rear passengers.

As for the boot, again it loses some volume because it’s not a wagon-style SUV, but there’s still a decent, square floor space with a claimed 605 litres of capacity.

So, overall the Q8 obviously isn’t the most practical version of an SUV, but it does well given its focus on style.

Audi updated the Q8 range earlier this year, with refreshed looks after seven years on sale and a plug-in hybrid powertrain to cater for new demand.

A new RS Q8 is coming later in the year, but the RS Q8 Performance has arrived first to make a bigger impact. It naturally gets a performance boost, but there are some other extras beyond more kilowatts.

These include RS ceramic brakes, lightweight 23-inch forged alloy wheels, Pirelli P-Zero tyres, unique aluminium inlays and a special RS layout for the digital instrument display.

Which is good, because the RS Q8 Performance costs nearly $25k more than the ‘standard’ RS Q8, priced from $255,800 plus on-road costs.

Luckily for a car costing a quarter of a million bucks, there’s also plenty of luxuries too, including Nappa leather upholstery, four-zone climate control and a 17-speaker 730-watt Bang & Olufsen sound system, amongst others.

When you compare it to its rivals on performance terms, in particular the Urus and Cayenne Turbo, the $250k asking price doesn’t exactly look ‘cheap’ but it is good value in comparison.

The Audi is a touch pricier than the BMW X6 M Performance at $250,900, but quite a bit more affordable than the Mercedes-AMG GLE63 S Coupe at $268,900.

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.

This is the latest iteration of Audi’s twin-turbo 4.0-litre V8 petrol engine - and it’s a beauty.

While this engine is used in a variety of models, for the RS Q8 Performance Audi has taken power to 471kW with 850Nm of torque, which, as mentioned earlier, makes it the most powerful internal combustion engine Audi has ever offered in a production car.

That’s also a big boost over the previous RS Q8, which managed 441kW/800Nm, and is only just shy of the 485kW/850Nm offered by its ‘cousin’, the Porsche Cayenne Turbo GT.

Audi claims that the RS Q8 Performance will launch 0-100km/h in just 3.6 seconds and keep going to an electronically limited top speed of 250km/h. We tried to test the acceleration time on a closed circuit, but driving into a very strong headwind the big SUV could manage only 4.4 seconds - which is still a very quick time given its size and luxury.

The engine is paired to an eight-speed automatic transmission and Audi’s trademark quattro all-wheel-drive system to help smoothly transmit so much power to the road.

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.

Unfortunately you don’t get the most powerful production engine without some trade-off, and for the RS Q8 Performance that means significant fuel consumption. The official fuel economy rating is a very thirsty 12.2L/100km, but that's the best-case scenario too. If you partake in some spirited driving that unleashes the full potential of the engine will result in a higher rate of premium unleaded being consumed by the big V8. We saw returns in the high teens across our time, but that was largely open road driving, so we’ll reserve final judgement for an extended test drive across more varied conditions.

Thankfully there’s a fairly large 85L fuel tank, so if you can hit the claimed average you can get a theoretical 696km of range.

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.

Obviously the RS Q8 Performance is all about speed, Audi made its intention clear by sending it to the Nurburgring to set a new SUV lap record for an SUV. But the reality is most owners are unlikely to hit the racetrack in the RS Q8, so what’s it like on the road?

In a word? Impressive.

While the engine is undoubtedly the star attraction offering up so much effortless performance, the RS Q8 Performance wouldn’t be so quick around the Nurburgring or as nice to drive on the road without its highly advanced chassis systems.

It has an array of technology to help it handle, it has active air suspension, adaptive dampers, active roll stabilisation and all-wheel steering, which help to make this big SUV handle like a much smaller car.

The suspension does a remarkable job of providing a compliant ride on such large alloy wheels, while also providing responsiveness.

The handling is certainly helped by the all-wheel steering, which gets the rear wheels to turn in the opposite direction to the fronts at low speed (below 50km/h), but in the same direction at high speed (above 80km/h), making the big SUV feels much more direct when changing direction.

As for the overall experience, that’s helped by Audi’s surprising decision to actually remove some of the sound insulation, which allows you to hear the engine even more than you ordinarily would. This really plays to the dynamic nature of the RS Q8 Performance.

The RS Q8 Performance comes stacked with the full suite of active safety features. These include adaptive cruise control, lane change warning, rear cross-traffic alert and surround-view cameras.

ANCAP rated the Q8 as five stars back when it first launched in 2019 and that rating is due to expire at the end of 2025. However, ANCAP states that it only applies to the 3.0-litre Q8 models, not the V8-powered RS variants.

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.

Despite the extra power and fancy new brakes, the RS Q8 Performance costs the same to service as the existing RS Q8.

That means $4690 for Audi’s five-year service plan, and $5720 for the Audi Advantage.

The latter package includes an extra two-year, unlimited kilometre warranty on top of Audi’s five year/unlimited km coverage. It also includes two extra services and two more years of roadside assistance, to keep you covered for seven years total.

That’s good, but it’s still an extra cost when many mainstream brands already offer seven years of coverage as standard.
