Audi A6 2.0 TDI Ultra Review: Executive Efficiency, 60 MPG
Discover why the Audi A6 2.0 TDI Ultra excels in efficiency, luxury, and everyday performance for discerning drivers.

Audi A6 2.0 TDI Ultra: Efficiency Meets Executive Luxury
The Audi A6 2.0 TDI Ultra represents a pinnacle of engineering where fuel efficiency does not compromise on performance or refinement. This front-wheel-drive saloon delivers impressive real-world economy figures while wrapping occupants in premium comfort, making it a standout for long-distance travelers and company car drivers alike.
Powertrain and Performance Excellence
At the core of the A6 Ultra is a 2.0-liter TDI diesel engine producing 190 PS (approximately 188 bhp), paired with a seven-speed S tronic dual-clutch automatic transmission. This setup replaces the older Multitronic CVT, offering smoother shifts and better efficiency. Acceleration from 0-62 mph takes 8.2 seconds, with peak torque available across the mid-range revs for strong in-gear pull.
Drivers appreciate the engine’s affable nature; it punches above its weight on motorways, allowing relaxed cruising in top gear with minimal fuel use. Top speed reaches 144 mph, sufficient for most scenarios without excess. The front-wheel-drive configuration keeps weight down, contributing to the model’s eco-credentials without sacrificing usability.
Fuel Economy and Running Costs
Audi’s ‘Ultra’ badge signifies optimized efficiency through lightweight materials like high-strength steel and aluminum, low-rolling-resistance tires, and advanced stop-start technology. Official figures claim 64.2 mpg combined, with CO2 emissions at 114 g/km, placing it in the 23% company car tax band. Real-world tests confirm nearly 60 mpg on motorways and around 45-50 mpg in mixed urban driving.
| Metric | Value | Notes |
|---|---|---|
| Official MPG | 64.2 mpg | Combined cycle |
| Real-World MPG | 45-60 mpg | Motorway/highway focus |
| CO2 Emissions | 114 g/km | Low tax banding |
| 0-62 mph | 8.2 seconds | Adequate for executive class |
| BIK Tax (23% band) | From £80/month | Attractive for fleets |
These numbers translate to low benefit-in-kind (BIK) taxation, starting at £9,072 annually for higher-rate taxpayers, and lease deals under £300 per month for businesses. The subtle tweaks—like a coasting function in the gearbox—enhance frugality without visual compromises such as aero kits.
Design and Exterior Styling
The A6 Ultra avoids eco-car stereotypes with its poised, elegant lines available in trims like S line and Black Edition. The Black Edition variant amplifies presence with gloss black paint, darkened glass, smoked alloy wheels, and minimal chrome accents, creating a menacing yet sophisticated look. Larger wheels up to 20 inches maintain style without penalizing efficiency.
A discreet ‘Ultra’ badge on the tail hints at its green credentials, but the overall design prioritizes Audi’s signature athleticism. This approach appeals to executives who want substance over flashy badges.
Interior Comfort and Technology
Step inside, and the A6 envelops you in luxury. Full leather seats, a 6.5-inch infotainment screen with sat-nav, keyless entry, and parking sensors come standard in S line spec. The cabin’s quiet repose shines on motorways, with supple leather and logical ergonomics fostering relaxation.
- Seating: Supportive front seats with ample rear space for adults.
- Infotainment: Intuitive MMI system, responsive touchscreen.
- Climate: Dual-zone automatic with effective ventilation.
- Storage: Generous boot (530 liters) and practical cubbies.
Options can escalate costs, but the base equipment suffices for most, blending work and leisure seamlessly.
Handling and Ride Quality
While not the most engaging in corners compared to rivals like the BMW 5 Series, the A6 Ultra prioritizes composure. The suspension absorbs motorway undulations effortlessly, delivering a sublime long-haul experience. Front-drive setup provides secure grip, though it feels relaxed rather than sporty on twisty roads.
Steering is precise, and the S tronic gearbox responds promptly, enabling effortless overtakes. For sharper dynamics, quattro models with larger engines exist, but the Ultra excels in serene efficiency.
Practicality for Daily Use
This saloon’s spaciousness suits families or professionals hauling gear. Rear legroom accommodates tall passengers, and the boot swallows weekend luggage with ease. Fuel stops are infrequent, ideal for high-mileage users. Urban maneuverability benefits from sensors and a tight turning circle, despite its size.
Rivals and Market Position
The A6 Ultra competes with efficient executive saloons:
- BMW 520d EfficientDynamics: Similar economy, sportier handling.
- Mercedes E220 CDI BlueEfficiency: Refined but pricier.
- Jaguar XF 2.2D: Stylish alternative with engaging drive.
Starting around £34,365, it undercuts some peers while matching luxury and costs.
Long-Term Ownership Insights
Owners praise reliability, with the Euro 6 engine proving durable. Maintenance follows Audi’s schedule, and resale holds strong due to brand prestige. Fuel and tax savings offset premium fuel prices.
