What's the difference?
BMW has recently launched its fourth-generation (G45) X3 range, which comprises three petrol variants including the entry-level 20 xDrive, mid-grade 30e xDrive PHEV and top-shelf M50 xDrive.
The new trio brings revised powertrains, new exterior and interior styling, increased standard equipment, enhanced technology and an emphasis on the use of sustainable materials.
We recently trialled the five-seater flagship to see if it has the right mix of performance and practicality to maintain the X3’s enduring appeal for Aussie families.
The Audi Q7 has come in for its second facelift as it enters its ninth year of production while the younger Q8 is in for its first refresh.
But these two aren't like the Mitsubishi ASX and Eclipse Cross pair; Audi's MLB underpinnings were cutting edge at their launch 2015 and remain stand-out in the class with advanced suspension and chassis tech, connectivity and refinement.
A host of small visual and performance tweaks aim to make the range-topping SQ7 we're driving even better. But should you make the sensible seven-seat decision or go a little rogue and choose the sloping-roofed SQ8?
This is a highly competent all-rounder, given that it has the comfort and practicality for urban family duties yet with its revered M breeding can produce a level of performance which, in competent hands, could hold its own at a track day where its capabilities could be safely explored.
There are newer options than the current Audi SQ7 and SQ8, including those which use the same platform, but don't write these luxury large SUVs off just yet.
It's a rare thing that a vehicle costing $200,000 has an air of pragmatism about it, but the SQ7 does. Its sensible leather upholstery, decent practicality, towing capability and near-excess of interior space make it a great family wagon.
As a counterpoint, the sharper looking SQ8 has minimal trade-off in comfort and interior room (at least for five) and is the kind of statement piece you'd expect for the price — especially in one of its loud paint colours.
Whichever way you leap, it's true that while the SQ7 and SQ8 are ageing, they are doing so gracefully and remain a superb option in this segment.
Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.
The fourth-gen X3, which has a lighter but stiffer body, shares the same wheelbase as its third-gen predecessor but at 4755mm end-to-end it's 34mm longer and it's 29mm wider.
It’s also 25mm lower, which combined with front and rear track-width increases and adaptive suspension damping to sharpen the handling underlines its sportiness and driver appeal, despite a substantial 2055kg kerb weight.
The new exterior design is characterised by short overhangs, flush door handles, a larger ‘split kidney’ grille, new LED taillights and L-shaped light elements for the LED headlights.
The new interior design is a classy mix of soft-touch materials and high-gloss hard surfaces in tastefully contrasting tones. The seats are upholstered in a new synthetic leather called 'Veganza' ('Espresso Brown' in our example) which according to BMW requires 85 per cent fewer CO2 emissions to produce than genuine leather (which is still available as an extra-cost option).
Combined with subtle use of ‘Magnolia’ fine-wood trim inserts, satin chrome, piano black, blue/red M highlights and slender ambient light-strips, it’s a cabin that exudes opulence.
If you're getting an SQ7, you'll want to tick the 'Black Pack' box because otherwise there are a lot of high-gloss silver details, especially at the rear that don't suit this tall and slightly awkward SUV.
The SQ8 is more convincing, appearing wider on the road with its new 'singleframe' grille design seemingly sucking it even closer to the tarmac like some kind of overgrown Audi RS3.
Both get an attractive new 2D design for the Audi rings and L-shaped grille details. These aid the SQ7's front end which is more muscular and purposeful than before.
The attractive lights have moved higher up the front end for enhanced presence, too. You get Matrix LEDs as standard but these candles are the hardcore HD Matrix items that feature laser light for further even longer light throw at night. They are simply awesome.
Fresh 22-inch alloy wheels and minor changes to badges finish off the exterior treatment for both cars.
The SQ8's bold specification — finished here in 'Sakhir Gold' — sets it apart from other SUVs as the metallic gold paint shimmers in the sunlight. The SQ8 is also available with whopping great 23-inch alloy wheels that you see here.
Inside, both cars share a similar architecture with 10.1-inch touchscreen for the multimedia and an 8.6-inch item below for heating and ventilation settings.
The SQ7 is a great example of a design ageing without dating, its confident horizontal lines and well-proportioned cabin features are as attractive as they were at launch, if less impressive than the related VW Touareg's whopping 15-inch screen or the minimalist Range Rover Sport.
Adding to the feeling of quality is that signature Audi smell — a combination of leather and the Sensory Package's perfume, no doubt. The SQ7 keeps a round-bottom steering wheel which remains one of the best in the business, it's just the right size and diameter trimmed with dimpled leather.
Final flourishes include the optional contrast red stitching and seatbelts as well as eye-catching turned aluminium trims.
This would make a great family weekend escape machine, for which BMW quotes a 645kg payload rating. It’s also rated to tow up to 2500kg of braked trailer, which could pose a challenge given the relatively low 100kg tow-ball download limit (TBD is typically around 10 per cent of trailer weight).
BMW also does not publish a GCM figure (how much it can legally carry and tow at the same time) so we can’t confirm if it can carry its maximum payload while towing its maximum trailer weight.
Even so, the M50 has a useful-sized luggage area which offers up to 570 litres (or 0.57 cubic metres) of load volume with the rear seat upright.
This expands to 1700 litres (or 1.7 cubic metres) with the rear seat folded flat, which can be handy for a multitude of tasks like transporting a mountain bike or hauling home flat-pack furniture.
There’s comfortable space for the driver and front passenger, along with useful storage including large bottle-holders and bins in each front door.
The centre console has two small-bottle/cupholders plus wireless phone-charging and a pair of USB ports. There's also a glove box plus another box at the rear of the console with a padded lid that doubles as an elbow rest.
The rear bench seat is surprisingly spacious, given that I’m 186cm tall and when seated behind the driver’s seat in my position I still have about 40mm of knee clearance, which is optimised by the concave shape of the front seat backrests.
The spacious and airy feel is enhanced by the ‘panorama’ glass roof which spans the full length of the seating area and allows generous headroom even for tall people.
However, shoulder room is tight for three adults and the centre passenger’s feet must contend with the transmission tunnel, so even though it would be fine for three kids we’d suggest a limit of two adults for longer trips.
Rear passengers get privacy glass and pull-up roller sunshades, large-bottle holders and bins in each door plus net-type pockets and anchorage points for media devices on each front seat backrest. There are also two small-bottle/cupholders in the fold-down centre armrest.
The rear of the centre console has two USB ports, adjustable air-vents plus controls for zone temperature, airflow preferences and seat-heating.
The bench seat features a 40/20/40 split, which allows the centre backrest to fold forward independent of the two outer backrests to allow long loads like snow skis, home hardware etc to be carried if securely fastened.
A power tailgate provides access to the luggage area, which is equipped with a handy 12-volt accessory socket plus load-anchorage points front and rear, extra storage nooks for small items on either side and a retractable roller-type load cover. Overall, this vehicle offers good practicality for family duties.
The difference between aged and dated is best summed up, though, by the excellent usability of the SQ7's cabin controls.
The separate screen for ventilation, for example, makes it simple to adjust seat or vent temperatures without interrupting the main screen's navigation instruction or other media systems.
When using wireless Apple CarPlay and Android Auto the top screen is entirely devoted to the other software with no remnants of Audi's system. It runs smoothly at all times.
Switching back to Audi's system, and there's a lack of contrast to the dark main screen and navigation. The touch targets are huge, though, and the satisfying click of the haptic feedback is welcome when driving. It seems expensive and natural in a world of feel-free touch operation.
Audi's 12.3-inch digital driver's display remains one of the best in the business. Legible and customisable with bespoke sport modes and the ability to show a full-size map, if you wish.
You can keeping devices charged with a wireless pad or there are two USB-C ports under the cushy centre armrest. A 12-volt socket is also available, and two more charge points are found in the back.
If there's one criticism in the front, it's the fairly limited storage. The door bins are big enough for a 600mL bottle but not much more and beneath the armrest the tray is shallow. The only other storage spots are the two cupholders which are the perfect size for a small take-away coffee.
While on the critiques, the drive mode selector is awkwardly hidden near the passenger below the touchscreen.
The seats are amazingly comfortable with ample support and power adjust for everything, including under-thigh length and bolsters. Several massage programs can be accessed through the menus, too.
Continuing the comfortable seating, the SQ7's second row is capacious with plenty of head, leg and toe room even for those over 180cm.
The bench slides forwards and backwards manually and the backrest is adjustable. A fold-down armrest contains two more small cupholders, and there are two separate climate zones, two vents and heated outboard seats.
However, folding and unfolding the second row is a bit complex and quite heavy work with a strange mix between electric and manual movement to access the third row — a Nissan Pathfinder does this better.
Once back there, the third row is passable for adults providing the second row is slid forward.
There are ISOFIX ports and top tether anchors for both power-deployed third row seats, so you can fit up to five children's seats in an SQ7.
The SQ8's second row is still generous but you do lose a small amount of headroom owing to the sloping roof design.
You also sacrifice some boot space, at 608L with five seats and 1755L with the second row folded. That's still a lot but the spacious SQ7's 793L/1921L figures are even better and 295L with all seven seats up is respectable. Both have sturdy 40/20/40 split-fold rear seats.
As the vehicles are equipped with air suspension, owners can raise or lower the boot floor to make it easier to load bulky objects if needed. A power tailgate is standard on both models.
A retractable luggage cover, netted pocket, boot lights and some underfloor storage complete the boot, however both cars lack a spare tyre of any sort. A tyre inflation kit is included.
Our X3 M50 xDrive test vehicle, finished in new 'Dune Grey Metallic', comes standard with a 3.0-litre turbocharged inline six-cylinder petrol engine incorporating 48-volt mild-hybrid technology, plus an eight-speed automatic and permanent all-wheel drive for a list price of $128,900.
You’d expect a high performance prestige vehicle costing six figures would be packed with desirable standard features and the M50 xDrive delivers, starting with big 21-inch 'M' lightweight alloy wheels shod with wide 285/35R21 tyres.
However, there’s no room for a spare (not even a space-saver) so you get a tyre repair kit instead.
The standard equipment list also includes adaptive LED headlights (with matrix high-beam and blue design detailing), a power tailgate, an ‘Iconic Glow’ illuminated kidney grille with M-specific elements, quad exhaust outlets, a panorama full-length (fixed) glass roof, a choice of six premium metallic paint colours and more. The 'M Sport Pro' visual enhancement package is also included.
Step inside and the driver is treated to a head-up display and an elegantly curved digital dash display, which spans about two-thirds of the cabin's width. It seamlessly incorporates a 12.3-inch driver’s instrument display (made from recycled polyester) and 14.9-inch multimedia display controlled by BMW’s latest 'iDrive System 9' software.
Premium audio is provided by a 15-speaker 750-watt Harman Kardon surround sound system, which includes digital radio and wireless Apple/Android connectivity. There’s also wireless phone charging.
The driver gets a thick leather-rimmed and heated 'M Sport' flat-bottom steering wheel and the driver and front passenger are also treated to sumptuous bucket seats with multiple power adjustments and heating/cooling.
Up to three passengers can share the rear bench seat and indulge in the luxury of three-zone automatic climate control, heating for the outer seating positions, privacy glass, roll-up sunshades, two USB-C ports and lots more.
Audi's range of Q7 and Q8 large SUVs starts at $117,284 for the 45TDI and there's a plug-in hybrid version from $152,284, both before on-road costs. The flagship SQ7 and SQ8 are $174,815 and $178,815, respectively.
The pair is a rare example of a discounted new car, albeit by a slim $585, so you'd expect these behemoths to offer comprehensive standard specification.
Features such as 22-inch alloy wheels, ambient interior lighting, soft close doors, power-adjust heated and ventilated seats, quad-zone climate control, 'Valcona' leather upholstery, a 17-speaker Bang & Olufsen sound system, full-length sunroof, navigation and a head-up display are included.
Naturally, options are available in packs and standalone choices with all vehicles we drove featuring at least one of the expensive box-ticks.
The 'Sensory Pack' seems a logical choice, bundling a 23-speaker, 1920-watt sound system with raising tweeters, 'Dinamica' headlining, massage seats, heated rear seats, Audi's air ioniser and interior perfume, extended leather upholstery and rear sun shades for $14,400.
Another major option is the $10,900 'Dynamic Package' with active roll stabilisation and Quattro Sport rear differential.
Stand-out stand-alone options include HD Matrix LED and Laser headlights combined with customisable OLED rear signatures ($3950) and the black exterior styling packages ($1850, or $2550 for the Plus version).
The as-tested price for the tow pack-equipped ($1500) 'Daytona Grey' car we spent most time in was rather high at $209,215 before on-road costs — that's over $30K worth of extras.
According to BMW, the M50 xDrive features the most powerful inline six-cylinder petrol engine fitted to an M Performance model.
This 3.0-litre unit clearly benefits from BMW’s twin-scroll turbocharging technology, which combined with variable valve timing and an extra 13kW/200Nm from the 48V mild-hybrid technology produces a stomping 293kW of power at 5500rpm and 580Nm of torque at 1900rpm.
It also has a ‘boost’ function, which provides an extra burst of power for short periods when maximum acceleration is required when overtaking etc.
It’s activated by the left paddle-shifter on the steering wheel and automatically optimises transmission/chassis settings to suit. There’s also a drive mode selector, with ‘Sport’ offering the most responsive and engaging experience.
The eight-speed torque converter automatic is a refined and efficient transmission well suited to this full-time all-wheel drive application. Rapid-fire manual shifting is also available using the steering wheel paddles.
The SQ7 and SQ8 both use a 4.0-litre twin-turbo 'hot vee' V8 petrol after the diesel SQ7 was abandoned in mid-2022.
It is the same engine you'll find in just about every application of this MLB platform, including the Porsche Cayenne, Bentley Bentayga and Lamborghini Urus — though it makes more power elsewhere.
In Audi's two medium-sporty SUVs it produces 373kW at 5500rpm and 770Nm between 2000-4000rpm.
In practice, it's a swelling, punchy engine without much top-end sparkle — though 4.1 seconds to 100km/h is nothing to scoff at.
The V8 also produces a rather splendid soundtrack, striking the right balance between Detroit burble and motorsport bark for this application.
An eight-speed torque converter auto transmission has been retuned for improved shift logic and it remains buttery smooth. It's pleasing enough just manoeuvring slowly around a car park, where you can feel just well calibrated the long travel throttle and transmission logic are.
BMW claims an official average combined consumption of 8.2L/100km but the dash display was showing 9.9 at the completion of our 210km test, which included a mix of suburban, city and highway travel.
Our own figure, calculated from fuel bowser and tripmeter readings, came in slightly higher again at 10.5L/100km, which given our test vehicle’s two-tonne-plus weight and performance capabilities is still reasonable economy.
So, based on our figures, you could expect a realistic driving range of around 600km from its 65-litre tank, which prefers premium 98 RON petrol.
With 2340kg to heave around, not even the 48-volt mild hybrid system can save the SQ7's fuel consumption — it's a thirsty beast.
The rated ADR combined cycle (urban, extra-urban) figure is 11.8L/100km and indulging in the ample performance resulted in 16.5L/100km on the trip computer. The SQ8 was much the same.
The SQ7 is certified to tow up to 3500kg (braked), equal to a Toyota LandCruiser or Nissan Patrol.
A fairly large 85L tank gives the SQ7 a theoretical driving range of around 720km from a fill-up. Naturally, 98 octane unleaded is required.
First, the fun stuff. It certainly feels like ‘the ultimate driving machine’ when you slide behind the chunky leather-rimmed flat-bottom steering wheel and hold it in your hands.
The driver’s seat offers not only powered adjustment of backrest and base-cushion rake, but also four-way lumbar support and side-bolsters that can tighten their embrace of your upper torso to contend with high cornering loads.
There’s also manual extension of the base-cushion length for greater thigh support and a big left footrest to brace against, so you could not ask for a more accommodating and purposeful driving position.
The steering is perfectly weighted and the quartet of enormous disc brakes provide ample bite with superb pedal feel. Combined with its adaptive suspension and wide grippy tyres, the X3 is a family car that’s also invigorating to drive, particularly when you select the ‘Sport’ mode.
The enhanced engine response and sharper steering that result (even the instrument panel display changes) make any twisting mountain road an engaging experience, enhanced by an intoxicating exhaust note that only a BMW M six can deliver.
The turbocharged engine offers an unyielding surge of acceleration from well below peak torque at 1900rpm to maximum power at 5500rpm, making BMW’s claim of 0-100km/h in a scant 4.6 seconds sound credible.
You can also manually change gears using the steering wheel paddles, but we found the gearing and shift calibrations so good that we preferred to leave it in auto mode.
However, the X3 M50 has two distinct personalities, as in more relaxed drive modes it’s just as happy serving as practical family transport during the week for grocery shopping, daily school runs and other common tasks.
It’s also a comfortable tourer for family getaways, with long gearing that requires only 1500rpm to cruise at 100km/h where low engine, tyre and wind noise allow highway conversations at lounge room levels.
Our drive loop started in South-East Sydney where the SQ7's burbly V8 and air suspension fitted right in, easily soaking up the worst of the concrete expansion joints and sharp-edged potholes.
It is a joy to waft around in the refined SQ7 with its remarkably good vision out the front and back (with 360-degree cameras to help elsewhere). Standard rear-wheel steer allows the back tyres to rotate up to 5.0 degrees, giving the 5072mm long SQ7 a better turning circle (12.5m) than a Q3 small SUV.
Its driven home further by the excellent drive mode customisation. Along with the standard programs, you can set an 'Individual' mode up with various selections for the suspension, steering, powertrain response and exhaust noise.
Following the SQ7, our time in the SQ8 took in some more twisting roads and the combination of 23-inch alloys with firmer suspension settings meant that, even in 'Comfort', 'Auto' or 'Balanced' drive modes, the coupe-styled model had a busier ride.
Both SQ7 and SQ8 featured 'Sport' adaptive air suspension, sitting 15mm lower than normal with the ability to drop the ride height up to 40mm in 'Dynamic' mode or raise it 50mm in lift mode to get out of sticky situations.
Audi chose not to specify the Dynamic pack on the SQ8, though, and the difference is noticeable compared to the SQ7. The coupe SUV rolls a little more in hard cornering and doesn't engage the rear end in quite the same way.
Back in the SQ7, turn in may feel a little less sharp owing to the taller height but the active roll stabilisation and Quattro electronically-controlled limited-slip differential splitting power between the two rear wheels makes for a more confident vehicle with better punch out of corners.
Grip is prodigious and the SQ7 is always in control with 285/35R22 Bridgestone Turanza T005 tyres.
A 2.4-turn lock-to-lock steering system is well-judged, remaining light in Comfort but adding enough weight and precision in Dynamic.
The brakes — 400mm front rotors clamped by six-piston calipers with optional ceramics — are reassuring and feel Autobahn ready.
The Audi SQ7 with Dynamic Pack is like an Olympic swimmer that's put on some kilos and had a few kids but can still gap his teenage son in a 50-metre freestyle race.
This is perhaps the perfect expression of Audi's 'S' models USPs, being totally normal when pottering despite huge reserves of talent.
No ANCAP rating as yet but this X3 comes with a long menu of standard safety features including multiple airbags, AEB with pedestrian/cyclist/junction detection, front collision warning with brake intervention, lane-keeping, active cruise control, head-up display with speed sign recognition, front and rear cross-traffic alert, tyre pressure monitoring and lots more.
There are also ISOFIX and top tethers for the two outer rear seating positions.
The Audi SQ7 is currently unrated by local ANCAP safety authority but Euro NCAP awarded a Q7 50TDI a maximum five stars in 2019.
It features eight airbags, adaptive cruise control, lane-keep assist, blind-spot monitoring, rear cross-traffic alert, surround-view monitor and exit-warning system to stop occupants dooring cyclists.
The adaptive cruise control is smooth and natural, although we found the lane-keep and lane-trace programs to be a little overbearing. Both can be easily disabled by holding the button at the end of the indicator stalk for about five seconds.
It comes standard with a five-year, unlimited km warranty.
Scheduled servicing is determined by BMW’s vehicle monitoring system which advises when a service is needed, typically around 12 months/15,000km.
A capped-price servicing package covering five years/80,000km (whichever occurs first) totals $2475, or an average of $495 per service.
Audi recommends SQ7 and SQ8 owners bring their car in for a service every 12 months or 15,000km.
Service pricing is not cheap, with a five-year package costing $4600 for either model. For reference a basic service plan for a BMW X5 costs $3450 for five years.
Audi has moved to a five-year, unlimited kilometre warranty with owners able to extend that (for a fee) up to nine years with Audi Advantage. An extra two years of warranty and scheduled servicing costs $4360 for the SQ7 and $4160 for SQ8.
Additionally, customers get access to Audi's loyalty programs with event invitations, ambassador experiences and discounts offers from select partner companies.
