BMW X3 vs Audi Q5

What's the difference?

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.

The third-generation Audi Q5 in TDI quattro form is a competent if unremarkable all-rounder that would tick most boxes for private or commercial use. Whether it’s the best buy of the 21 brands and 34 models that compete in Australia’s congested ‘Medium SUVs over $60K’ segment, only a customer can decide after weighing up its many alternatives.

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.

The Q5 TDI quattro rides on a 2823mm wheelbase and is 4717mm long, 1900mm wide and 1662mm tall with an 11.9-metre turning circle, so it’s a comfortable fit for metropolitan car parks. It has sophisticated five-link suspension, four-wheel disc brakes and electric power-assisted steering.

The third-generation Q5 features fresh styling with its prominent grille treatment the most noticeable feature. Overall, the standard S line exterior has an athletic look, which is optimised by our example’s larger 20-inch wheel option which nicely fills the wheel arches.

The interior has an open and airy feel, enhanced by the contrasting dark grey/pearl beige upholstery and panoramic sunroof options.

There are lots of soft-touch surfaces, exposed stitching and satin chrome highlights, plus (unfortunately) piano black surfaces on the dash and console which shine like mirrors when clean but can quickly turn opaque with unsightly fingerprints during everyday use.

Good design can be seen in the prominent ledge created by the dash inlay at the base of the central touchscreen, as you can comfortably rest the base of your palm on it to steady your index finger when using the touchscreen while driving, which is much easier and less distracting than trying to do this without such support.

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 Q5 TDI quattro weighs almost two tonnes (1955kg kerb weight) which when deducted from its 2595kg GVM rating leaves 640kg of load capacity, which for either work or play is ample for up to five adults plus luggage of which up to 75kg can be carried on the roof.

It’s also rated to tow up to 2000kg of braked trailer but Audi does not publish a maximum legal weight for the car and trailer combined (not unusual in this vehicle segment), so we can’t confirm if it can carry its full in-car load capacity when towing its maximum trailer weight.

The expansive ‘Digital Stage’ multimedia screen spans about two-thirds of the dashboard’s width, above a decent sized glove box and another compartment to the right of the driver’s knee for small items.

Driver and front passenger also have access to a bottle-holder and bin in each door plus there’s a 12V socket, two USB-C ports and a wireless phone-charging pad in the centre console, which also provides two cupholders and a storage box with padded lid that doubles as a comfortable elbow rest.

The rear bench seat offers adequate space for tall adults, given I’m 186cm and when seated behind the driver’s seat set in my position I have about 40mm of knee clearance and about the same dimension in head clearance, even with the optional sunroof.

It’s less comfortable in the centre seat obviously, with feet either side of the transmission tunnel and knees together between the front seat backrests. Shoulder room is tight for three adults, which is tolerable for short trips but a maximum of two would be ideal for longer treks.

Rear passengers get a bottle-holder in each door plus elastic net pockets on both front seat backrests. The rear centre seat backrest also folds forward to reveal two cupholders and the rear of the centre console has adjustable air vents and a pair of USB-C ports, plus third-zone climate control adjustment.

The fully carpeted rear luggage area is equipped with another 12V socket plus tidy bag, first-aid kit and four load-anchorage points. The rear section of the load floor is hinged, which when opened reveals a large underfloor storage compartment.

With the rear seat upright, this luggage area offers more than half a cubic metre of load volume. And with the seat folded flat this expands to almost 1.5 cubic metres, with a large flat floor suitable for carrying everything from a mountain bike to flat-pack furniture.

Our test vehicle is the Q5 TDI quattro which comes standard with a turbocharged 2.0-litre four-cylinder diesel engine, seven-speed automatic and all-wheel drive for a list price of $87,600.

That’s around the same spend as a Lexus NX 350H F Sport +Ep1 Hybrid AWD ($87,900) or Mazda CX-60 P50E Azami PHEV ($87,050). The NX and CX-60 are also the strongest-selling model ranges in the ‘Medium SUVs above $60K’ market segment where the Q5 competes.

The Q5 TDI quattro’s standard equipment includes 19-inch alloys with 235/60 R18 tyres but no spare (repair kit only), sporty 'S line' appearance package, matrix LED headlights with configurable signatures, LED tail-lights with dynamic indicators, an electric tailgate with gesture control (wave your foot under the rear bumper to open), heated/auto-dimming exterior mirrors and more.

The interior has power-adjustable and heated leather-appointed seating, three-zone climate control, a leather-rimmed steering wheel with paddle-shifters and multifunction controls, colour ambient lighting, matt brushed aluminium inlays, 360-degree camera view, speed sign recognition, eight-speaker audio system, inductive phone charger with adaptive cooling, combined 11.9-inch OLED driver instrument display and 14.5-inch OLED colour multimedia screen with wireless Apple/Android connectivity and more.

Our test vehicle is enhanced with numerous options including Navarra Blue metallic paint ($2000) plus the ‘Premium Package’ comprising head-up display, Bang & Olufsen 3D premium sound system, colour interior ambient lighting with dynamic interaction light, USB interfaces with higher charging capacity and acoustic glazing for the front door windows ($5400).

It’s also equipped with the ‘Style Package’ that bundles 20-inch Audi Sport alloy wheels (wearing 255/45 R20 tyres on our example) with a black exterior package and privacy glass ($4900).

On top of these extras there’s an optional panoramic sunroof with tinted glass and electric tilting/opening/retractable sunshade ($3500) plus 'natural brown walnut trunk' dash inlays ($600) and a pearl beige upholstery package which is a no-cost option (NCO).

So, when you add the combined cost of all these goodies ($16,400) our test vehicle’s list price crosses into six-figure territory at $104,000.

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 turbocharged 2.0-litre four-cylinder diesel engine meets tough Euro 6 emission standards using AdBlue and produces 150kW of power between 3800-4200rpm, with 400Nm of torque on tap between 1750-3250rpm.

It’s paired with Audi’s latest hybrid diesel-electric technology which can add up to 18kW of power and 230Nm of torque to these figures, while also allowing short periods of pure electric driving for low-speed manoeuvring and parking.

The seven-speed torque converter automatic offers the choice of sequential manual gear-changing using the steering wheel paddle-shifters, along with selectable drive modes to optimise Audi’s iconic ‘quattro’ all-wheel drive technology.

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.

Audi claims official combined average consumption of 5.9-6.8L/100km and the dash display was claiming 6.5 at the completion of our 364km test, which comprised our usual mix of suburban, city and highway driving with up to five adult occupants and light luggage.

Our own figure, calculated from fuel bowser and tripmeter readings, was 9.1L/100km which is still within the usual 2.3L/100km discrepancy between official and real-world figures. So, based on our test figure, you could expect a realistic driving range of around 700km from its 65-litre diesel tank.

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.

There’s a comfortable and spacious driving position as you’d expect, with ample seat and steering wheel adjustments combined with a large left footrest to enhance support.

It exhibits solid build quality and good driving dynamics, from its nicely weighted steering to its supple ride quality that optimises the Q5’s sprung weight to flatten the bumps.

Acceleration from the turbo-diesel engine comes in a smooth surge that benefits from the extra input of the electric hybrid system, which combined can deliver more than 600Nm of torque. However, at times we detected a slight delay in response when accelerating hard from standing starts or low speeds.

The automatic transmission shifts sweetly between its seven ratios and the all-wheel drive transmission delivers reassuring traction.

We also trialled the different drive modes, with ‘Dynamic’ providing the most energetic response, particularly when using the paddles in manual-shift mode. However, we spent most of our test in the ‘Balanced’ default setting, as it provides the best compromise between ride comfort and performance for everyday use.

Comes with a fresh five-star ANCAP rating (tested 2025) and comprehensive passive and active safety features including nine airbags, AEB, active front assist, blind-spot monitoring, exit warning, rear cross-traffic alert, front park assist, speed sign recognition, a 360-degree camera view including kerb view function and more. The rear seat has ISOFIX child seat anchorages for the two outer seating positions and top tethers for all three.

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.

The standard warranty is five years/unlimited km, which is shorter than rivals like Kia's EV5 with seven years. Scheduled servicing is every 12 months/15,000km whichever occurs first. Audi offers an upfront five-year service plan that covers the first five scheduled services up to five years/75,000km for $3520, or an average of $704 per service. This plan includes five years of roadside assistance.
