2018 Audi A6 Complete Review: Power, Tech, Value

The 2018 Audi A6 stands out as a versatile executive sedan that masterfully blends sophisticated luxury, impressive performance, and innovative technology. Updated for the model year with enhanced standard features and boosted power across its engine lineup, this vehicle appeals to business professionals and families seeking refinement without sacrificing capability. Its poised handling, spacious cabin, and premium materials position it as a formidable rival to icons like the BMW 5 Series and Mercedes E-Class.

Key Updates and Model Year Enhancements

For 2018, Audi elevated the A6’s appeal by making advanced features standard across trims. Every model now includes navigation via the upgraded MMI system with a larger display, keyless ignition and entry for effortless access, and improved engine outputs. The 3.0-liter V6 supercharged engine now delivers 340 horsepower and 325 pound-feet of torque in all variants, a boost previously reserved for higher-end models. Premium Plus trims gain LED headlights, while Prestige models add a 360-degree top-view camera for superior parking assistance.

A new Sport trim slots between base Premium and Premium Plus, featuring gloss-black exterior accents and interior trim for a more aggressive aesthetic. The Competition package, available on V6-equipped Premium Plus and Prestige models, introduces sport-tuned suspension, 20-inch wheels with summer tires, red brake calipers, black mirror caps, and a Quattro sport differential for sharper dynamics. Inside, it adds diamond-stitched sport seats, brushed aluminum accents, and a flat-bottom steering wheel with paddle shifters.

Engine Options and Performance Breakdown

The 2018 A6 offers three distinct powertrains, all paired with automatic transmissions for seamless power delivery. The base 2.0-liter turbocharged four-cylinder produces 252 horsepower and 273 lb-ft of torque, mated to a seven-speed dual-clutch automatic in front-wheel-drive models or an eight-speed automatic with Quattro all-wheel drive. It achieves EPA estimates of 25/34 mpg city/highway for FWD and 22/31 mpg for Quattro, balancing efficiency with adequate pep.

The supercharged 3.0T V6 shines with its newfound standard power, propelling the sedan from 0-60 mph in under five seconds while maintaining composure. The range-topping S6’s twin-turbo V8 unleashes 450 horsepower for thrilling acceleration, ideal for enthusiasts craving more intensity. Quattro all-wheel drive, Audi’s hallmark, enhances traction and stability, especially in adverse conditions, though it slightly impacts fuel economy.

Driving Dynamics: Balance of Sport and Serenity

Behind the wheel, the A6 impresses with agile handling and a compliant ride, earning high marks for its segment-leading dynamics. The 3.0T V6 provides effortless surge, complemented by precise steering and a well-calibrated chassis that inspires confidence on twisty roads. Even the base 2.0T feels lively, with the seven-speed S tronic dual-clutch gearbox shifting smoothly.

Comfort remains a priority, particularly on motorways where refinement excels. The suspension absorbs imperfections adeptly, even on larger 19-inch or 20-inch wheels with sport setups. Optional adaptive dampers further refine the experience, though the Sport package’s stiffer tuning prioritizes handling over plushness. Outward visibility aids maneuvering this sizable sedan, and drive modes like Dynamic sharpen throttle response and steering weight.

• Strengths: Responsive engines, Quattro grip, composed high-speed stability.
• Considerations: Less engaging than BMW rivals; sport packages reduce ride comfort.

Interior Luxury and Practicality

The A6’s cabin exudes understated elegance with high-quality materials like attractive wood trim, soft leather, and Alcantara accents in sport models. The design is driver-focused, featuring a classy layout with intuitive controls. Standard heated seats, a reversing camera, matrix LED headlights, cruise control, and smartphone integration via Apple CarPlay and Android Auto set a premium baseline.

Space is generous: front occupants enjoy supportive seats and ample headroom, while rear passengers benefit from plentiful legroom. The 565-liter trunk accommodates luggage easily, though it’s not the class leader. The optional Technology Pack introduces a 10.1-inch MMI touchscreen, 12.3-inch Virtual Cockpit digital gauge cluster, and wireless charging, elevating the tech-forward ambiance.

Build quality is exemplary, justifying the starting price around $50,000 for base models, with loaded Prestige variants exceeding $70,000. Visibility is excellent, aiding urban driving.

Safety and Advanced Driver Assistance

Safety features abound, with standard autonomous emergency braking, lane departure warning, and parking sensors. The 360-degree camera on Prestige trims simplifies tight maneuvers. In front collision tests, the A6 earned an Advanced rating, mitigating impacts effectively at various speeds.

Quattro enhances safety in wet or snowy conditions, and optional adaptive cruise control with traffic jam assist adds highway ease. Overall, it delivers peace of mind befitting a luxury family hauler.

Trims, Pricing, and Value Proposition

Starting at approximately $48,000 for Premium, the A6 scales to $70,000+ for Prestige. The Sport trim offers style upgrades without a steep premium, while the Competition package caters to performance fans. Leasing and company car incentives make it attractive for fleet buyers.

• Premium: Base luxury with nav, keyless entry.
• Premium Plus: LED lights, upgraded audio.
• Prestige: Full tech suite, 360-camera.
• Sport/Competition: Dynamic enhancements.

Depreciation is reasonable for the class, holding value well due to Audi’s reputation.
