Audi Q7 TDI or VW Touareg TDI — Which One is Better?

Which Diesel SUV to Buy – Audi Q7 TDI vs. VW Touareg TDI Comparison

Like the Mercedes Benz GLE and BMW’s X5, the Audi Q7 and Volkswagen Touareg are not always far from contradistinction—and for good reasons. The Audi Q7 and Volkswagen Touareg are pretty similar as they were developed side by side and also share the Volkswagen Group MLB platform and chassis.

Both vehicles belong to the midsize SUV class and are powered by Audi-developed diesel engines. The units are very advanced, with a plethora of hi-tech features; however, an Audi Q7 repair manual can help you understand what’s happening inside the engine and even help you with a DIY repair.

The Audi Q7 was the first SUV offering from Audi, initially introduced in 2006. Apart from its elegant style and exquisite interior, the seven-seater luxury SUV features cutting-edge technology.

On the other hand, Volkswagen introduced the Touareg in 2002, a midsize luxury SUV that features a five-seater configuration with an abundance of standard driver assistance features. It also has a high-end interior and offers a comfortable ride.

To determine which is the best buy between the 2021 Audi Q7 45 TDI and 2021 Volkswagen Touareg 170 TDI, we’ll examine different areas and specs and see how they compare to each other before giving a verdict.

Here we go!

Performance and Handling

Although both SUVs have identical engines and eight-speed automatic transmissions, the Q7 is slightly quicker, accelerating from 0-100km/h (0-62 mph) in 7.3 seconds. Meanwhile, the VW Touareg does the same in 7.5 seconds.

Getting off-road, the Q7 performs well against muddy dips and other off-roading conditions but struggles to crawl over rocks. The Touareg also performed just fine off-road, but you would be better with the limited edition Adventure variant if you want to take it off the beaten paths on a regular basis. It is fitted with extra off-road settings and several other features focused on exceptional off-road performance.

Both SUVs were designed to be fashionable and practical. While the Q7 can haul around 7,700 pounds with the optional tow package, the Touareg can tow about 7,716 pounds as standard.

Luxury and Convenience

The Q7 has a minimalistic yet luxurious cabin. The seven-seater SUV features a pleasant and nicely finished interior, eight-way power-adjustable heated front seat, and a power-folding third-row. The seats are pretty comfortable and offer adequate support and adjustability. The Q7 also includes a panoramic sunroof and a new 12.3″ infotainment system with an optional head-up display. With the Audi Q7, you should expect nothing less than luxury and advanced technology.

The Touareg is a robust SUV with excellent interior comfort as well as a luxurious feel. The cabin features a huge 15″ touchscreen infotainment on the center stack and an optional panoramic sunroof. Although the interior material in the Touareg doesn’t quite bring that premium feel like the Q7, the gigantic infotainment system provides the cabin with a magnificent outlook.

Furthermore, the Audi Q7 features an adaptive air suspension, allowing it to remain comfortable regardless of the road conditions. On the other hand, the 170TDI is the only Touareg to feature steel springs rather than air suspension in the lineup.


The 2021 Q7 still retained the upgrades from the previous year, which brought about remarkable changes, including the powerful turbocharged engine. Overall, the Q7 featured a flawless interior as well and exceptional build quality. The latest Touareg has also undergone significant upgrades in all the right areas, giving it a modernized look—it’s pretty much a tie here (or a question of personal taste).

Fuel Economy

The 170TDI has a better fuel economy with an average fuel consumption rating of 6.8L/100km (7.6L/100km city and 6.3L/100km highway). On the other hand, the Q7 has an average fuel consumption of 7L/100km (8L/100km city and 6.5L/100Kk highway).

The VW slightly has the edge here.

Maintenance and Reliability

The recommended oil change and filter replacement interval for the 2021 Audi Q7 with conventional oil is after 3,000 – 5,000 miles. For synthetic oil, the replacement should be between 7,500 – 10,000 miles. The same applies to the Volkswagen Touareg. However, if you regularly drive in a dusty environment or pull heavy loads, you might need to switch to the “severe driving” interval schedule.

Although both vehicles are decently reliable,   gave the Touareg a 3/5 reliability rating while the Q7 only managed to score 2.5/5.


Despite having a similar powertrain, the Q7 takes the lead on the road while the Touareg is at the forefront off-road. Both perform well in normal settings and have almost the same towing/hauling capacity.

Both SUVs feature a luxurious interior, and the Q7 makes up for its lack of storage space with its third-row seat. Although the Touareg has better fuel economy, it features steel springs rather than air suspensions. The result is that the Q7 has a smoother ride over uneven roads.

Of course, there are trade-offs here—you’ll just have to weigh your options and decide what matters most for you. The Q7 45 TDI is an excellent choice if you want to carry more passengers, provided you don’t mind paying a premium. However, the adaptive air suspension will more than make up for it.

On the other hand, if you are looking for more storage space, you can opt for the less expensive Touareg. Overall, you can never go wrong with either of the two, as they both have a history of exceptional performance.
