A Comprehensive Car Comparison by MCT Motorsport

For Australian buyers wanting a premium family SUV with strong highway touring ability, refined diesel power and prestige badge appeal, the 2024 Audi Q7 50 TDI S line and 2024 Mercedes-Benz GLE300 d are two standout options. Both deliver luxury interiors, advanced safety technology and strong long-distance comfort, but they approach the segment differently. The Audi Q7 focuses on practicality, seven-seat flexibility and understated sophistication, while the Mercedes-Benz GLE300 d leans into plush comfort, style and brand presence. If you are deciding between these two luxury diesel SUVs, this comparison breaks down the key differences.

Performance & Driving Experience

Audi Q7 50 TDI S line

9.2/10

The Q7’s 3.0-litre V6 diesel gives it effortless performance. With strong torque delivery and refined acceleration, it feels relaxed in urban traffic and highly capable on open roads. It is especially impressive when fully loaded with passengers or luggage.
Audi’s quattro all-wheel-drive system adds confidence in wet weather and gravel conditions, while adaptive suspension keeps the large SUV composed through corners.

Mercedes-Benz GLE300 d

8.8/10

The GLE300 d uses a smaller four-cylinder diesel, but it remains smooth and efficient. It delivers enough punch for daily driving and comfortable touring, though it does not feel as muscular or effortless as the Audi under heavy acceleration.
The GLE prioritises comfort over sporty dynamics, making it ideal for buyers wanting a soft, luxurious driving experience.

Interior & Comfort

Audi Q7 50 TDI S line

9.3/10

The Audi Q7 cabin feels sleek, premium and well engineered. Triple-screen digital displays, quality materials and clean design lines create a sophisticated atmosphere. Seating comfort is excellent, and the third row adds genuine practicality for families.
Road noise suppression is strong, and long-distance touring comfort is a major highlight.

Mercedes-Benz GLE300 d

9.5/10

Mercedes-Benz excels in cabin ambience. The GLE feels plush, elegant and highly luxurious, with sweeping dual screens, ambient lighting and premium trim finishes. Front-seat comfort is outstanding, and suspension tuning adds to the relaxed experience.
Rear-seat space is generous, though standard seven-seat practicality can favour the Audi depending on specification.

Technology & Safety

Audi Q7 50 TDI S line

9.2/10

Audi equips the Q7 with a strong suite of features including digital cockpit displays, smartphone connectivity, quality navigation and advanced safety systems. Parking cameras and driver aids make the large SUV easier to manage.
The infotainment system is polished, though it can take time to learn.

Mercedes-Benz GLE300 d

9.4/10

The GLE impresses with its MBUX infotainment system, voice controls and premium digital presentation. It feels especially modern and user-friendly. Safety systems are comprehensive, with advanced driver assistance features available across the range.
Mercedes has a slight edge for interface quality and wow factor.

Running Costs & Ownership

Audi Q7 50 TDI S line

8.5/10

The Q7 offers strong diesel efficiency for its size, though servicing and tyres can be expensive. The larger V6 engine may also carry higher running costs than smaller rivals.
Audi resale values remain solid in Australia, particularly for desirable diesel SUV models.

Mercedes-Benz GLE300 d

8.6/10

The smaller diesel engine can offer slightly lower fuel costs, and Mercedes servicing plans can help with budgeting. Insurance and maintenance still sit firmly in prestige territory.
Strong badge appeal also supports resale demand.

Practicality & Family Use

Audi Q7 50 TDI S line

9.6/10

This is one of the Audi’s strongest categories. Standard seven-seat flexibility, a large cargo area and easy access make the Q7 highly usable for families. It suits school runs, airport duties and interstate trips with ease.

Mercedes-Benz GLE300 d

8.7/10

The GLE offers generous cabin space and a large boot, but five-seat layouts in many variants mean it is not as flexible as the Audi. If seven seats are essential, buyers should check exact specification.

Design & Road Presence

Audi Q7 50 TDI S line

8.9/10

The Q7 is clean, modern and understated. S line styling adds sharper bumpers, larger wheels and extra visual presence without being flashy.

Mercedes-Benz GLE300 d

9.3/10

The GLE has stronger showroom presence, with a bold grille, elegant proportions and unmistakable Mercedes-Benz styling. It looks expensive and sophisticated from every angle.

Value for Money

Audi Q7 50 TDI S line

9.0/10

The Q7 offers V6 diesel performance, seven seats and premium technology at a competitive price point for the segment. For many buyers, it represents excellent value.

Mercedes-Benz GLE300 d

8.7/10

The GLE commands a higher asking price, but it returns strong luxury appeal, premium comfort and brand prestige. Buyers paying extra are buying the experience as much as the specification.

Our Verdict

50 TDI S Line 9.1/10

300 d 9/10

Two Excellent Luxury SUVs With Different Priorities

The 2024 Audi Q7 50 TDI S line is the smarter all-round choice for many Australian buyers. Its V6 diesel performance, seven-seat practicality and balanced value make it an outstanding family luxury SUV.

The 2024 Mercedes-Benz GLE300 d counters with superior cabin ambience, comfort and prestige appeal. It feels more indulgent and refined, particularly for buyers prioritising front-seat luxury.

If practicality and value matter most, the Audi stands out. If comfort and brand experience lead the decision, the Mercedes-Benz is hard to overlook.
