The 50 TDI's 3.0-litre turbo-diesel V6 produces 210kW and 600Nm, supported by a 48-volt mild-hybrid system. Power is delivered through an eight-speed tiptronic automatic transmission to Audi's quattro all-wheel-drive system.
With a claimed 0–100km/h time of 6.1 seconds, the Q7 delivers impressive acceleration for a large seven-seat SUV. More important in everyday driving is the generous torque available through the mid-range, giving it an effortless character when overtaking, merging or travelling with passengers and luggage.
Rather than feeling like a large SUV working hard to build speed, the 50 TDI's powertrain feels ideally matched to the Q7's size and grand-touring character.
Verdict: Refined, powerful and effortless, the V6 diesel is an excellent match for the Q7.
Capability is one of the strongest reasons to consider the diesel Q7. The 2024 Audi Q7 50 TDI S line is rated to tow up to 3,500kg braked, alongside a 750kg unbraked capacity.
That opens the door to larger caravans, boats and trailers while the 600Nm of torque, quattro all-wheel drive and substantial footprint provide the foundations for confident towing.
For buyers wanting a prestige SUV that can genuinely combine luxury family transport with demanding recreational duties, this is an important advantage.
Verdict: Outstanding towing capability adds genuine versatility to the Q7's luxury credentials.
For a sizeable seven-seat SUV with a powerful V6, the Q7 50 TDI offers respectable efficiency. Audi quotes combined consumption of approximately 6.8L/100km, although actual consumption will naturally vary with driving conditions, load and towing.
The diesel powertrain is particularly well suited to longer journeys, where its combination of torque and cruising efficiency gives the Q7 excellent touring credentials.
Buyers choosing the 50 TDI are therefore getting more than performance. The drivetrain also makes sense for the type of long-distance driving at which a large luxury SUV excels.
Verdict: Strong touring efficiency complements the diesel's impressive performance and range.
Step inside and the Q7 delivers the polished environment expected from Audi. Its clean dashboard architecture incorporates Audi's dual-touchscreen MMI system alongside the Virtual Cockpit digital instrument display, creating a cabin that feels both sophisticated and technology-focused.
S line specification adds further visual and tactile appeal, while three seating rows provide genuine flexibility for families. The third row is best suited to children or occasional adult use, but having seven seats significantly broadens the Q7's practicality.
Luggage capacity ranges from approximately 295 litres with all three rows in use to 1,908 litres with the rear seating folded, allowing the cabin to adapt easily between passengers and cargo.
Verdict: Beautifully presented, versatile and comfortable, with the flexibility expected from a flagship family SUV.
The Q7 takes a more restrained approach to luxury SUV styling than some of its rivals. Its broad Singleframe grille, distinctive lighting signature and strong proportions give it presence without relying on excessive visual drama.
The S line treatment brings sportier bumpers and exterior detailing, complemented by 21-inch alloy wheels with 285/40 R21 tyres.
At 5,067mm long and 1,970mm wide, the Q7 is undeniably substantial, but its clean surfacing and balanced proportions disguise some of that size. It is an elegant design that suits buyers looking for something sophisticated rather than overt.
Verdict: Understated, sophisticated and appropriately imposing in S line specification.
The 2024 Audi Q7 50 TDI S line offers an extensive suite of safety and driver-assistance technology, including:
The combination is particularly valuable in a vehicle of this size, with the surround-view camera and parking assistance helping make tighter urban environments considerably easier to negotiate.
The Q7 also received a five-star ANCAP rating under the 2019 testing protocols, including 92 per cent for adult occupant protection and 87 per cent for child occupant protection.
Verdict: A comprehensive safety and assistance package that adds confidence to everyday driving.
The Q7's appeal lies in how many roles it can perform without feeling compromised. It offers premium presentation, strong performance, seven-seat practicality, quattro all-wheel drive and serious towing ability in one polished package.
For a used buyer, specification, service history, condition and provenance remain important considerations. A well-kept 50 TDI S line with a strong history represents an attractive opportunity to access a highly capable large luxury SUV.
Prestige servicing and ownership costs should naturally be factored into the decision, but the breadth of capability helps justify the investment.
Verdict: A highly complete luxury SUV that delivers considerable capability for the money.
Final Verdict: Should You Buy the 2024 Audi Q7 50 TDI S line?
The 2024 Audi Q7 50 TDI S line succeeds because it doesn't force buyers to choose between luxury and utility. Its powerful V6 diesel provides effortless performance, the seven-seat cabin makes it genuinely family-friendly, and its 3,500kg braked towing capacity gives it capability well beyond the school run.
It also retains the refinement, technology and understated design that make Audi's larger models so appealing. Buyers considering alternatives such as the BMW X7, Mercedes-Benz GLE or Land Rover Discovery will find the Q7 particularly compelling if diesel performance, towing and everyday versatility are high on the priority list.
For the buyer seeking one prestige SUV capable of doing almost everything, the Q7 50 TDI S line makes an exceptionally strong case.
