Audi Q8 45TDI (2025) Review – Can diesel still cut it in an electric world?

We get behind the wheel of a striking 45TDI quattro Black Edition finished in a rare Sakhir Gold Metallic to see if the turbodiesel still has a place in a luxury car.
We Like: Simple big diesel engine, handles exceptionally well for a large SUV.

Audi Q8 45TDI Summary
- The 3.0-litre V6 turbodiesel engine is a standout, offering excellent power and torque for a nimble and responsive driving experience while remaining surprisingly fuel-efficient.
- The Q8 has a “ludicrous” price tag, especially with optional extras, making it prohibitively expensive.
- While the interior design is starting to look dated with its multi-screen fascia, it is user-friendly and offers a high level of luxury, build quality, and practicality, with ample luggage and passenger space.
- The body control is exceptional, and the quattro all-wheel drive system provides great security, though the ride quality is slightly compromised and firm due to the large 22-inch wheels, with 20-inch wheels probably being ideal.
What’s the Audi Q8 like to live with?

Living with the Audi Q8 is, in many ways, an exercise in contradictions. It is an exceptionally well-built and luxurious vehicle, yet its price tag is simply staggering. Its asking price, as tested, is a ludicrous R2.284 million (including options); most consumers will do a double-take, especially when you consider that a more sensible price point of around R1.5 million would make it a far more compelling proposition.
For this kind of money, you are firmly in the territory of established rivals such as the BMW X6 and the Mercedes-Benz GLE Coupe. Both models offer stiff competition in terms of tech and luxury features, plus performance, forcing potential buyers to seriously consider whether the Q8 is worth the money.
However, beyond the price, the daily experience is one of pure premium motoring. The build quality is excellent, with every panel and surface feeling well-constructed. The unique Sakhir Gold Metallic colour is not for the shy, but it’s a great conversation starter; Its sandy hue makes it look like an SANDF vehicle.
The practicality is surprising for a coupe-styled premium SUV. The sloping roofline doesn’t compromise rear headroom as much as one would expect, and there’s plenty of space to load things. The luggage capacity of 605 litres is more than sufficient for holiday trips or a family’s worth of shopping. In essence, the Q8 is an easy and comfortable car to live with, provided you can look past the initial sticker shock.
Audi Q8 Performance and Efficiency

The heart of the 45TDI quattro Black Edition is its magnificent 3.0-litre V6 turbodiesel. In a world obsessed with electrification, it’s a refreshing reminder of what a great diesel engine can produce. The colossal 600 Nm of torque that the 45TDI delivers defines the driving experience. The Audi Q8 is a sizeable SUV, but the effortless surge of torque from low down in the rev range makes it feel nimble and responsive. It’s the kind of power that lets you overtake on the highway with a mere flex of your right foot.
The big turbodiesel feels completely uncomplicated, delivering a seamless blend of power and efficiency without the complexities and weight penalties of a petrol-electric hybrid system. The 8-speed tiptronic transmission is a perfect partner, shifting smoothly and intelligently to keep the engine in its power band.

The performance is nothing short of glowing, with a claimed 0-100 kph time of just 7 seconds. In the real world, our testing data suggested it was even quicker; it dispatched the benchmark sprint in 6.74 sec.
This kind of acceleration is more than what most people will ever need, but not at the cost of fuel efficiency. Audi claims a combined fuel consumption of 7.8 L/100 km, and the test unit indicated an average return of 8.5 L/100 km at the end of its tenure in our fleet. Suffice it to say that the turbodiesel powertrain is remarkably frugal for a vehicle of this size, offering over 1 000 km per fill-up.
Features and Practicality of the Audi Q8

As for the interior, the Audi Q8 is starting to show its age. The multi-screen fascia layout, which was once considered cutting-edge, now feels a generation behind some rivals with their single, seamless screens.
However, this dated feel has a significant silver lining. It means there are still physical buttons to access often-used functions such as climate control, volume, and the seat heaters. This makes operating the car an intuitive experience, avoiding the need to dive into complex touchscreen menus for simple tasks.

The build quality is excellent, and the whole cabin exudes a sense of solid, Teutonic luxury. The Valcona leather with S embossing and rhombus stitching pattern is a highlight – it feels supple and premium to the touch. The front seats are electrically adjustable with a memory function, while the included seat ventilation and massage function ensure maximum comfort on long journeys.
Other notable features include the digital OLED rear lights (which do a light show when you press the key fob to unlock the Q8), a head-up display, and the comprehensive suite of driver assistance systems, including adaptive cruise control and blind-spot assist.
As previously mentioned, the load bay’s luggage capacity is ample at (a claimed) 605 litres, and with the seats folded down, this expands to a van-like 1 755 litres, making the Audi highly practical indeed.
Ride and Handling

The ride quality of this particular Audi Q8 is slightly compromised, primarily due to the stunning 22-inch wheels. While they look fantastic and perfectly fill the arches, giving the car a powerful stance, they are arguably a size or two too big.
The large wheels’ low-profile tyres have insufficient sidewall depth to absorb imperfections in the road, resulting in a ride that can be a bit firm over rough surfaces. A set of 20-inch wheels, shod with plumper rubber, would undoubtedly provide a softer, more compliant ride that would be ideal for daily driving.

Still, the 45TDI quattro Black Edition handles exceptionally well for a large SUV. The quattro all-wheel drive system provides immense grip and security in all weather conditions, and the steering is precise and well-weighted. It’s not a sportscar, but the Q8 feels surprisingly agile and stable when tackling twisty roads.
The tiptronic automatic transmission and the powerful turbodiesel engine work together seamlessly, allowing the driver to feel connected to the road. The Q8 45TDI quattro manages to balance its luxurious nature with a dynamic and engaging driving experience.

Audi Price and After-sales Support
The Audi Q8 45TDI quattro Black Edition is listed at R2 011 700 (August 2025). That is quite steep as is, but when you add R272 300 worth of optional extras, the final price – R2 284 000 – is astronomical.
When you compare the Q8 with its BMW X6 xDrive30d M Sport and Mercedes-Benz GLE450d coupe 4Matic AMG Line rivals, it becomes clear the Q8 is an expensive proposition and not the default choice.

Verdict

This Audi Q8 is easily one of the most enjoyable vehicles we’ve driven all year. The potent and efficient diesel engine is a triumph that proves the oil-burner is not yet a relic of the past, and the car’s well-built, user-friendly interior makes it a joy to use daily. The unique Sakhir Gold Metallic colour is a definite conversation starter, and the car as a whole is a true luxury SUV with a dynamic character and genuine practicality. The only real issue, and it’s a significant one, is the astronomical price tag. If you can justify the cost, you’re getting a well-rounded, well-engineered, and deeply satisfying vehicle.
