Audi Q8 vs BMW X5 Australia: Which Luxury SUV Should You Buy in 2026?

Choosing between the Audi Q8 and BMW X5 in Australia is not easy. Both are premium German SUVs offering powerful engines, sophisticated technology, luxurious interiors and the kind of road presence that makes them stand out in a crowded car park.

However, despite competing in the same luxury SUV segment, they have noticeably different personalities.

The Audi Q8 prioritises elegant styling, refinement and a sporty, coupé-inspired appearance. The BMW X5 focuses more heavily on driving dynamics, everyday practicality and the latest automotive technology.

There's also an important development for Australian buyers in 2026: BMW is introducing an entirely new fifth-generation X5 in late 2026, bringing more powerful engines, updated styling and a redesigned interior.

That makes this comparison particularly interesting because buyers can consider the established Audi Q8, outgoing BMW X5 stock or the incoming new-generation BMW.

In this comprehensive guide, we'll compare the Audi Q8 and BMW X5 in Australia across pricing, engine performance, fuel consumption, comfort, dimensions, boot space, technology, reliability, servicing costs and towing ability.

By the end, you'll have a clearer idea of which luxury SUV best suits your lifestyle and budget.

Audi Q8 vs BMW X5 Australia: Quick Comparison

Before exploring the details, here's how the Australian-market Audi Q8 compares with the incoming fifth-generation BMW X5.

Prices are indicative Australian manufacturer list prices before on-road costs and optional equipment. The BMW figures refer to the new-generation petrol and diesel models scheduled for late 2026, not the outgoing X5. Specifications can vary by model and equipment.

The first thing we notice is how closely these vehicles compete on price.

However, the BMW offers more engine power in its new-generation models, while the Audi provides a higher maximum braked towing rating.

2026 Audi Q8 vs BMW X5 Price in Australia

Pricing is one of the most important considerations when shopping for a luxury SUV.

Neither vehicle is inexpensive, and adding premium paint, upgraded wheels, interior packages or advanced technology can significantly increase the final drive-away cost.

Audi Q8 Price Australia

The MY26 Audi Q8 range includes three main powertrain choices.

The Q8 50 TDI offers strong diesel torque and long-distance touring ability, while the 55 TFSI provides a smoother petrol-powered alternative.

For buyers interested in electrification, the 60 TFSI e plug-in hybrid combines substantial performance with the ability to drive shorter distances on electricity.

Performance-focused SQ8 and RS Q8 versions sit above the regular range.

BMW X5 Price Australia

BMW's incoming fifth-generation X5 has two confirmed launch variants.

Both are scheduled for Australian introduction during the final quarter of 2026.

For comparison, the outgoing X5 range includes the xDrive30d, xDrive40i and xDrive50e plug-in hybrid, with original list prices beginning around $139,900, $143,900 and $154,900 respectively.

The new X5 plug-in hybrid and fully electric iX5 are planned for 2027.

Which SUV Offers Better Value?

On confirmed new-generation list pricing, the BMW X5 40d costs approximately $500 less than the Audi Q8 50 TDI.

Meanwhile, the petrol BMW X5 40 costs approximately $1,500 more than the Audi Q8 55 TFSI.

Those are relatively minor differences for vehicles costing almost $150,000.

We believe the more important factors are standard equipment, driving characteristics, practicality and the final negotiated drive-away price.

Buyers should also investigate dealership offers on outgoing-generation BMW X5 stock, particularly as the new model approaches Australian showrooms.

Price verdict: Both are closely matched, although the BMW X5 delivers particularly competitive pricing considering the additional power of its new engines.

Audi Q8 vs BMW X5 Exterior Design

Exterior styling is one of the clearest differences between these luxury SUVs.

Audi Q8: Sleek and Sophisticated

The Audi Q8 is designed to look sportier than a conventional large SUV.

Its roofline slopes gently towards the rear, creating a coupé-like silhouette without becoming as dramatic as some dedicated SUV coupés.

Some particularly attractive design elements include:

• Large Audi Singleframe grille
• Matrix LED headlights
• Strong shoulder lines
• Sporty S line exterior detailing
• Wide rear lighting design
• Large alloy wheels
• Low, athletic proportions

The result is a sophisticated SUV that looks expensive without necessarily appearing overly aggressive.

The Q8 is especially attractive for buyers who want the presence of a large SUV but prefer a sportier silhouette.

BMW X5: Bold and Muscular

The BMW X5 adopts a more traditional premium SUV shape.

Its taller roofline, upright proportions and prominent kidney grille create a muscular appearance.

The new fifth-generation X5 introduces BMW's latest design language, bringing redesigned lighting, distinctive body surfaces and a more contemporary front end.

It looks substantial and purposeful, particularly with M Sport styling.

The X5's traditional shape also has practical benefits, especially when loading bulky luggage.

Design verdict: We prefer the Audi Q8 for its elegant, sporty proportions, while the BMW X5 appeals more to buyers who enjoy a bold and commanding SUV.

Audi Q8 vs BMW X5 Interior Quality and Luxury

Both manufacturers have extensive experience creating premium interiors, but their approaches are different.

Audi Q8 Interior

Inside the Audi Q8, the emphasis is on luxury, clean surfaces and beautifully integrated technology.

The dashboard features Audi's dual-touchscreen MMI system alongside the digital Virtual Cockpit instrument display.

Depending on specification, highlights include:

• Valcona leather upholstery
• Heated front sports seats
• Audi Virtual Cockpit
• Dual central touchscreens
• Ambient interior lighting
• Multi-zone climate control
• Premium Bang & Olufsen audio
• High-quality decorative trim

The Q8 feels especially luxurious during relaxed motorway driving.

Its supportive seats and refined cabin are well suited to Australian touring conditions.

One potential drawback is the reliance on touch-sensitive controls.

Adjusting climate settings on a touchscreen can require more attention than turning a conventional dial.

BMW X5 Interior

The outgoing BMW X5 already has an impressive interior, with its Curved Display, comfortable seats and premium materials.

However, the incoming fifth-generation X5 brings a more substantial technological change.

Its redesigned cabin introduces BMW Panoramic iDrive, featuring an expansive digital interface and information projected across the lower windscreen area.

The new model also offers a large central display and available premium features such as:

• Heated and ventilated front seats
• Massage functionality
• Panoramic glass roof
• Premium audio systems
• Advanced ambient lighting
• Head-up display technology
• Sophisticated voice and digital controls

Australian launch specifications are particularly well equipped, although some individual items remain optional.

The new X5 feels more technology-focused, whereas the Audi offers a more established and traditionally polished luxury environment.

Interior verdict: The Audi Q8 is an excellent choice for refined luxury, but the new BMW X5 has the stronger claim to cutting-edge cabin technology.

Audi Q8 vs BMW X5 Performance

Both vehicles offer powerful six-cylinder engines, automatic transmissions and all-wheel drive.

However, the latest BMW X5 has a noticeable power advantage.

Audi Q8 Engine Options

The Australian Q8 offers the following main powertrains.

The diesel engine is particularly suited to long-distance touring.

Its strong torque delivery makes it comfortable when overtaking, travelling with passengers or towing a substantial trailer.

The petrol engine feels smoother and more responsive at higher engine speeds.

Meanwhile, the plug-in hybrid offers impressive acceleration thanks to the combined output of its petrol engine and electric motor.

New BMW X5 Engine Options

The new-generation BMW X5 arrives with two six-cylinder engines.

Both use 48-volt mild-hybrid technology.

The petrol X5 is especially impressive, delivering 44 kW more than the regular Q8 55 TFSI.

The diesel also produces substantially more torque than the Q8 50 TDI.

In everyday driving, however, both vehicles provide more than enough acceleration for Australian highways.

Which Is Faster?

Among the conventional petrol and diesel versions, the new BMW X5 has the stronger performance figures.

BMW X6 Year Models in Australia: Complete Guide to Every Generation (2008–2026)

The X5 40 xDrive completes the 0–100 km/h sprint in a claimed 5.3 seconds, making it a particularly quick large SUV.

The Audi Q8 60 TFSI e plug-in hybrid is also exceptionally quick, with a claimed time of approximately 5.0 seconds.

However, comparing a plug-in hybrid directly against a conventional petrol SUV is not entirely fair because their powertrain configurations differ.

Performance verdict: The BMW X5 wins for conventional six-cylinder engine performance. The Audi Q8 plug-in hybrid remains a compelling performance alternative.

Audi Q8 vs BMW X5 Fuel Consumption in Australia

Fuel economy matters even when buying an expensive luxury SUV.

Australian owners frequently cover long distances, whether commuting through major cities or travelling between regional centres.

Audi Q8 Fuel Economy

Official combined fuel consumption figures for the Australian Q8 are approximately:

The diesel is the most straightforward choice for buyers regularly travelling long distances.

The petrol engine uses more fuel but provides a smooth and refined driving experience.

The plug-in hybrid can achieve very low petrol consumption when regularly charged and used for shorter journeys.

However, its official fuel consumption figure includes a specific test cycle with electric driving. It should not be interpreted as the typical consumption of a vehicle driven with a depleted battery.

BMW X5 Fuel Economy

For the outgoing X5 generation, official combined figures include:

The incoming X5 40 petrol has a provisional combined consumption range of approximately 8.6–9.3 L/100 km, depending on specification.

A directly comparable final Australian combined figure for the new 40d diesel should be confirmed before purchase.

Which Uses Less Fuel?

Comparing outgoing-generation engines, the Audi Q8 diesel has a lower claimed consumption figure than the BMW X5 xDrive30d.

However, the incoming BMW generation introduces different engines and mild-hybrid systems, so the comparison will change.

Real-world economy will depend on:

• Driving style
• Vehicle weight and accessories
• Urban versus highway driving
• Traffic conditions
• Tyre pressure
• Air-conditioning use
• Towing and passenger loads

For drivers covering 20,000 kilometres or more annually, we would give serious consideration to a diesel version of either SUV.

For short daily commutes with convenient home charging, a plug-in hybrid may offer better fuel savings.

Audi Q8 vs BMW X5 Dimensions and Size

Both are large SUVs, but their dimensions influence practicality, manoeuvrability and passenger comfort.

The BMW is marginally longer and wider, although the differences are unlikely to be noticeable when driving.

Its biggest dimensional advantage is height.

The taller body provides a more traditional SUV seating environment and helps accommodate a generous cargo area.

The Audi Q8 is lower, contributing to its sportier appearance.

Which SUV Is Easier to Park?

Neither vehicle is particularly compact.

Both measure nearly five metres long and approximately two metres wide before including mirrors.

That makes underground shopping-centre car parks and narrow suburban driveways worth considering.

A surround-view camera system can make a meaningful difference when navigating tight spaces.

Although the Q8 sits lower, there is little difference in their overall parking footprint.

For buyers living in central Sydney, Melbourne or Brisbane, we recommend physically checking driveway and garage dimensions before deciding.

Audi Q8 vs BMW X5 Boot Space

Boot capacity is an important consideration for families and long-distance travellers.

The regular Audi Q8 provides approximately 605 litres of luggage capacity, expanding to around 1,755 litres with its rear seats folded.

The new BMW X5 offers approximately 655 litres, expanding to 1,850 litres.

That gives the BMW a 50-litre advantage with the rear seats upright.

The X5 also benefits from its more upright rear body design, which can make loading large suitcases, prams and other bulky items easier.

What About Plug-in Hybrid Boot Space?

Hybrid batteries can affect cargo capacity.

The Audi Q8 60 TFSI e offers approximately 439 litres, noticeably less than conventional Q8 versions.

The outgoing BMW X5 xDrive50e provides approximately 500 litres.

Specifications for the incoming new-generation X5 plug-in hybrid should be checked when that model launches.

For families with young children, the difference between 439 litres and more than 650 litres may be more important than a small difference in acceleration.

Boot space verdict: The BMW X5 wins for practicality and luggage capacity.

Audi Q8 vs BMW X5 Rear Seat Comfort

Both luxury SUVs comfortably accommodate four adults, with a fifth seating position available in the middle of the rear bench.

The Audi Q8 has a spacious cabin despite its sloping roofline.

Most adults should find adequate headroom and legroom, making it suitable for family road trips.

The BMW X5 provides a more upright seating position and an airier cabin impression.

The new generation's longer wheelbase also helps create generous interior proportions.

For families with child seats, both SUVs have the width and interior space expected of large luxury vehicles.

However, the ease of securing child seats can vary depending on seat design and the specific restraint.

We recommend testing your own child seats before purchase.

Can the Audi Q8 or BMW X5 Have Seven Seats?

The Audi Q8 is a five-seat SUV.

Some versions of the outgoing BMW X5 could be configured with an optional third row, depending on market and model specification.

The new-generation X5's initial Australian launch models are five-seaters.

Buyers who specifically require seven seats should check vehicle availability rather than assume every X5 offers that option.

If seven seats are essential, the Audi Q7 or BMW X7 may be more suitable alternatives.

Audi Q8 vs BMW X5 Ride Comfort

Luxury SUVs need to deliver more than impressive specifications.

Ride comfort becomes particularly important on Australia's mixture of smooth motorways, ageing suburban roads and rough regional highways.

Audi Q8 Ride Quality

The Q8 places considerable emphasis on refinement.

Adaptive air suspension contributes to its comfortable driving character, while the quattro drivetrain provides confident traction.

At highway speeds, the Q8 is well suited to relaxed cruising.

Its cabin is designed to isolate occupants from road imperfections and unwanted noise.

Large optional alloy wheels can still affect ride quality, particularly over potholes and uneven surfaces.

BMW X5 Ride Quality

The BMW X5 traditionally combines comfortable suspension with a more engaging driving experience.

The incoming generation continues this approach with adaptive suspension technology and sophisticated electronic chassis systems.

It feels intended to satisfy drivers who want a luxury SUV that remains composed through winding roads.

The trade-off is that sportier suspension settings and larger wheels can make certain road surfaces feel firmer.

Which Is More Comfortable?

We would favour the Audi Q8 for buyers prioritising relaxed, refined highway travel.

The BMW X5 is likely to appeal more strongly to people who appreciate responsive handling.

However, comfort is subjective, and a direct test drive on the same roads is essential.

Audi Q8 vs BMW X5 Driving Experience

A luxury SUV weighing well over two tonnes will never behave exactly like a sports sedan.

Nevertheless, both Audi and BMW have invested heavily in managing their vehicles' weight and improving handling.

Audi Q8 Driving Dynamics

The Q8 offers a stable, reassuring driving experience.

Its quattro all-wheel-drive system provides strong traction, especially during wet weather and on demanding road surfaces.

The steering is precise enough for everyday driving, and the suspension balances comfort with body control.

Its personality is more relaxed than aggressively sporty.

For extended highway journeys, that can be a significant advantage.

BMW X5 Driving Dynamics

BMW has long positioned the X5 as a luxury SUV with engaging handling.

The new generation continues this philosophy with powerful engines, a sophisticated chassis and rear-biased xDrive all-wheel drive.

It should appeal to drivers who enjoy steering response, controlled cornering and strong acceleration.

On winding regional roads, these characteristics can make the BMW particularly rewarding.

Driving verdict: The BMW X5 is our choice for enthusiastic drivers, while the Audi Q8 is particularly appealing for relaxed touring.

Audi Q8 vs BMW X5 Technology and Infotainment

Technology is a major selling point in this segment.

Both vehicles provide extensive digital functionality, but the incoming BMW X5 introduces a noticeably newer interface.

Audi Q8 Technology

The Q8 features Audi's established MMI infotainment system.

Depending on equipment, features include:

• Digital instrument display
• Satellite navigation
• Smartphone integration
• Premium sound system
• Voice control
• Multi-zone climate settings
• Parking cameras
• Driver assistance features

The dual-touchscreen dashboard looks sophisticated and creates a clean, modern appearance.

However, some buyers may prefer more physical controls.

BMW X5 Technology

The new BMW X5 introduces its Panoramic iDrive system, combining a large central touchscreen with information displayed along the lower windscreen.

This approach allows drivers to view important information without relying solely on a traditional instrument cluster.

Other available technologies include advanced parking assistance, premium audio and connected vehicle functions.

BMW's updated interior is a significant technological step beyond the outgoing X5 generation.

Technology verdict: The new BMW X5 takes the lead for its newer digital architecture, although the Audi Q8's system remains capable and luxurious.

Audi Q8 vs BMW X5 Safety Features

Both vehicles are equipped with modern active and passive safety technology.

Depending on variant and specification, equipment can include:

• Autonomous emergency braking
• Adaptive cruise control
• Lane departure warning
• Lane-keeping assistance
• Blind-spot monitoring
• Rear cross-traffic assistance
• Parking sensors
• Surround-view cameras
• Multiple airbags

The Audi Q8 has an established safety record, while the incoming BMW X5 introduces updated driver assistance technology.

However, safety ratings should not be assumed to transfer automatically between generations or drivetrain variants.

At the time of this comparison, the new-generation X5 does not yet have a published ANCAP assessment.

Australian buyers should check the current applicable ANCAP rating, its assessment date and the precise vehicle specification.

Audi Q8 vs BMW X5 Towing Capacity Australia

Towing is particularly relevant for Australian SUV buyers.

Whether you're towing a caravan, boat or horse float, maximum towing capacity can influence which vehicle is suitable.

The new-generation BMW X5's launch models have a lower rated maximum braked towing capacity than the conventional Audi Q8 models.

This is an important distinction because buyers familiar with the outgoing X5 might expect the same 3,500 kg rating to continue.

Which Is Better for Towing a Caravan?

The Audi Q8 50 TDI is a strong candidate thanks to its 600 Nm of torque and 3,500 kg maximum braked towing rating.

The new BMW X5 40d provides an impressive 670 Nm but has a 3,000 kg rated towing limit in its launch specification.

For heavier caravans, that difference could be decisive.

Nevertheless, maximum towing capacity is only one part of the equation.

Buyers must also check:

• Gross vehicle mass (GVM)
• Gross combination mass (GCM)
• Tow-ball download
• Payload remaining after passengers and luggage
• Trailer weight distribution
• Applicable licence and towing requirements

A vehicle rated to tow 3,500 kg cannot necessarily carry a full passenger and luggage load while towing at its maximum rating.

Towing verdict: The Audi Q8 has the advantage over the new-generation BMW X5 launch models for maximum braked towing capacity.

Audi Q8 vs BMW X5 Reliability

Reliability is one of the most frequently discussed topics when comparing expensive European SUVs.

Both Audi and BMW manufacture sophisticated vehicles containing complex electronics, turbocharged engines, advanced transmissions and driver assistance systems.

That technology provides impressive performance and comfort, but repairs outside warranty can be expensive.

Is the Audi Q8 Reliable?

The Q8 uses established Volkswagen Group engine and drivetrain technology.

Its V6 petrol and diesel engines are capable of delivering strong performance and substantial mileage when correctly maintained.

However, owners should be aware of potential long-term maintenance costs involving:

• Air suspension components
• Electronic modules and sensors
• Cooling system components
• Diesel emissions-control systems
• High-voltage hybrid components on PHEV models
• Complex infotainment equipment

These are potential areas of maintenance or repair, not defects that every Q8 will experience.

A complete service history is particularly important when purchasing a used example.

Is the BMW X5 Reliable?

The outgoing BMW X5 has several established powertrains, including well-regarded turbocharged inline-six engines.

However, ownership costs can increase with age and mileage.

Potential repair expenses may involve:

• Cooling system components
• Suspension systems
• Electronic control modules
• Diesel emissions equipment
• Air-conditioning components
• Plug-in hybrid systems
• Advanced infotainment electronics

As with the Audi, preventive maintenance can reduce the risk of more expensive problems.

The incoming fifth-generation X5 is too new to support a meaningful long-term reliability comparison.

Which Is More Reliable?

We wouldn't declare either the Audi Q8 or BMW X5 the outright reliability winner.

Both are complex premium vehicles, and actual reliability depends on the engine, production year, maintenance history and individual vehicle.

For buyers planning to own either SUV beyond the factory warranty, we recommend allowing for potentially substantial maintenance expenses.

Audi Q8 vs BMW X5 Maintenance and Servicing Costs

Servicing costs can have a significant effect on long-term ownership.

Both SUVs require high-quality components and specialist maintenance.

Audi Q8 Servicing

The Audi Q8 generally follows scheduled servicing intervals of around 12 months or 15,000 kilometres, depending on the vehicle's service requirements.

Audi Australia offers service packages that can help owners plan maintenance expenditure.

Additional expenses may include brake components, tyres, wheel alignment and repairs not covered by warranty.

BMW X5 Servicing

BMW uses a condition-based servicing system on many models.

This monitors factors such as vehicle usage and maintenance requirements rather than relying entirely on a fixed distance interval.

BMW also offers servicing packages for eligible vehicles.

Service pricing for the new-generation X5 should be confirmed with an Australian dealer.

Which Is Cheaper to Maintain?

There is no guaranteed winner.

Audi Q7 vs BMW X5 Australia: Which Luxury SUV Makes More Sense?

Costs can vary substantially depending on engine type, mileage, driving conditions and service inclusions.

Both vehicles benefit from a five-year, unlimited-kilometre new-car warranty in Australia.

However, normal wear items and maintenance are generally separate from warranty coverage.

We recommend comparing five-year servicing quotes for the exact variants being considered.

Audi Q8 vs BMW X5 Insurance Costs in Australia

Insurance is another expense worth investigating before purchasing a luxury SUV.

Both vehicles are expensive to repair, particularly when replacement parts involve advanced lighting, cameras, sensors or specialist bodywork.

Comprehensive insurance premiums depend on factors including:

• Driver age and driving history
• Residential postcode
• Annual kilometres
• Vehicle variant
• Agreed versus market value
• Insurance excess
• Parking arrangements
• Claims history

Higher-performance models generally cost more to insure.

However, it is impossible to say that the Audi Q8 always costs more or less to insure than the BMW X5.

The most useful approach is to obtain comprehensive insurance quotes for both vehicles using identical driver information and cover conditions.

Audi Q8 vs BMW X5 Resale Value

Depreciation is often one of the largest ownership costs for premium vehicles.

A luxury SUV can lose a substantial amount of its original purchase value during the first several years.

Both Audi and BMW have recognised names in the Australian premium market.

However, retained value depends heavily on specification, market demand, mileage and condition.

Audi Q8 Resale Considerations

The Q8's distinctive styling and luxurious interior may appeal strongly to buyers seeking something different from a conventional SUV.

However, its higher original price and more specialised body style can influence the used-car market.

BMW X5 Resale Considerations

The X5 has an established position in Australia's luxury SUV segment.

Its practical body design and broad engine selection appeal to a wide range of customers.

Nevertheless, the arrival of a new generation can affect demand and prices for outgoing models.

Buyers purchasing runout X5 stock should consider both the initial discount and likely future depreciation.

Resale verdict: The BMW X5 has broad appeal, but neither model has a guaranteed resale advantage. The actual purchase price and ownership period matter more than the badge alone.

Audi Q8 or BMW X5 for Australian Roads?

Australia presents some unusual challenges for luxury SUVs.

Drivers may spend one day travelling through heavy metropolitan traffic and the next covering several hundred kilometres on regional highways.

Best for City Driving

Both vehicles offer excellent visibility aids, automatic transmissions and comfortable seating.

Their size is the biggest drawback in congested urban areas.

The Q8's lower roofline may appeal to buyers who prefer a sportier vehicle, while the X5's more upright design provides a commanding driving position.

Best for Highway Touring

The Audi Q8 makes an excellent long-distance cruiser.

Its comfortable suspension, refined cabin and strong diesel engine create a relaxed touring experience.

The BMW X5 also performs exceptionally well on highways, with the added benefit of a more engaging chassis.

Best for Country Roads

The X5's handling-focused character makes it particularly appealing on winding regional roads.

However, tyre selection and suspension settings can influence comfort on coarse-chip surfaces.

Best for Light Off-Road Driving

Both have sophisticated all-wheel-drive systems suitable for additional traction on gravel roads and slippery surfaces.

However, neither should be confused with a dedicated heavy-duty off-road vehicle.

Low-profile tyres, expensive wheels and limited underbody protection can become disadvantages on rough tracks.

For demanding off-road travel, a purpose-built 4WD may be more appropriate.

Audi Q8 vs BMW X5 Plug-in Hybrid

Electrification is becoming increasingly important for Australian luxury car buyers.

The Audi Q8 60 TFSI e and BMW X5 xDrive50e offer a combination of petrol and electric driving.

However, availability differs between generations.

Audi Q8 60 TFSI e

The Audi Q8 plug-in hybrid produces a combined 360 kW and 700 Nm.

It offers a claimed electric-only driving range of approximately 74 kilometres under the WLTP test cycle.

That could cover many daily commutes without using much petrol, provided the battery is regularly charged.

Its biggest compromises are additional vehicle weight and reduced luggage capacity.

BMW X5 xDrive50e

The outgoing X5 xDrive50e produces a combined 360 kW and 700 Nm and offers up to 94 kilometres of claimed electric range.

The new-generation X5 plug-in hybrid is planned for 2027, with BMW quoting up to 102 kilometres of WLTP electric range for the forthcoming model.

Those figures refer to different vehicle generations and should not be treated as current showroom alternatives until the new model becomes available.

Which Plug-in Hybrid Is Better?

The outgoing BMW X5 xDrive50e offers greater claimed electric range and more luggage capacity than the Q8 plug-in hybrid.

However, the Audi has a higher maximum rated braked towing capacity.

The right choice depends on whether electric commuting, cargo space, towing or purchase timing matters most.
