Dimensions and Construction
While specific full dimensions for all 2025 A6 variants (sedan, Allroad, e-tron) might vary slightly, the A6 e-tron is noted to be "pretty much on par with the 2024 A6 gasoline model" in size. The e-tron leverages Audi's Premium Platform Electric (PPE) architecture, characterized by a long wheelbase and short overhangs, contributing to its optimized aerodynamics. The body-color grille on the A6 e-tron subtly signals its electric powertrain, differing from traditional ICE models. Functional air curtains and active cool-air intakes are integrated into the front fascia for aerodynamic efficiency.
The use of advanced materials is consistent across the lineup, emphasizing rigidity and weight optimization. For instance, the presence of an aluminum hood can be confirmed via a simple magnet test, indicating Audi's commitment to lightweight construction where beneficial.
Lighting and Visibility
The A6 e-tron features slim Daytime Running Lights (DRLs) complemented by a black mask that discreetly hides the primary headlight functions. While the IIHS headlight rating for the 2025 models has not been released, previous Audi models have achieved varied ratings. For instance, some earlier Audi A6 iterations received an "Acceptable" or "Marginal" rating for their headlights, highlighting an area where continuous improvement is often sought across the automotive industry to maximize nighttime visibility and safety. Audi's latest lighting innovation allows for customizable Daytime Running Lights with 8 selectable signatures, controlled via MMI® or the myAudi app.

Key Interior Metrics and Features
The A6 offers a spacious cabin, particularly noteworthy for its generous rear-seat area. Standard features include heated seats and tri-zone climate control. For 2025, the A6 Premium Plus trim gains standard ventilated front seats, and rear passengers benefit from four-zone automatic climate control for personalized comfort. The 55 TFSI Prestige trim offers standard contour front seats wrapped in Valcona/Milano leather with massage function, complemented by a leather-wrapped dashboard, armrests, and center console. Dual-pane acoustic glass side windows, also standard for 2025, significantly minimize exterior noise, contributing to a serene ride.
Technologically, the A6 is well-equipped. All 2025 Audi A6 models feature a 10.1-inch touchscreen infotainment display and Audi's Virtual Cockpit digital instrument panel (12.3-inch Audi virtual cockpit plus). The A6 e-tron further enhances the experience with an available augmented-reality head-up display, providing real-time vehicle information directly in the driver's line of sight.
Interior Quality and Noise Levels
While specific independent measurements for cabin noise at 70 mph for the 2025 model year are awaiting wider release, Audi vehicles are generally known for their excellent sound insulation. For context, typical luxury sedans often achieve cabin noise levels around 65-70 dB at highway speeds, which is below the industry average for many vehicle segments. The inclusion of dual-pane acoustic glass in the 2025 A6 lineup further underscores Audi's commitment to a quiet cabin environment.
Infotainment Responsiveness
Audi's MMI infotainment system typically offers intuitive operation and responsive feedback. While precise touchscreen lag times for the 2025 model are subject to independent testing, Audi systems generally aim for near-instantaneous responses, often outperforming segment averages. The latest iteration of Audi's E3 1.2 architecture, which controls all vehicle functions, emphasizes seamless data transfers and responsiveness.

Performance Section: Powertrains and Efficiency
The 2025 Audi A6 offers a compelling range of powertrain options, including updated gasoline engines and the all-new electric e-tron variants. This diverse offering ensures that buyers can select a vehicle that aligns with their performance and efficiency priorities.
Gasoline Powertrain Options
The traditional A6 sedan offers two turbocharged engine choices:
- 2.0-liter TFSI I4: Produces 261 horsepower and 273 lb-ft of torque. This engine is paired with a seven-speed automatic transmission and Audi's Quattro all-wheel-drive system. It provides a smooth and capable driving experience, with 0-60 mph acceleration around 6.1 seconds (45 TFSI Premium).
- 3.0-liter TFSI V6: Generates 335 horsepower and 369 lb-ft of torque. This V6 significantly enhances performance, making highway driving effortless and enabling spirited driving. The 0-60 mph time for the 55 TFSI Prestige is approximately 5.1 seconds.
The A6 Allroad, a luxury wagon variant, exclusively features the 3.0-liter turbocharged V6 engine, offering 335 horsepower and standard Quattro all-wheel drive. Both gasoline engines require premium gasoline.
Electric Powertrain: The A6 e-tron
The 2025 Audi A6 e-tron represents a significant shift, being the first A6 model to forgo an internal combustion engine. It is built on the Premium Platform Electric (PPE) architecture and promises impressive electric performance and range.
- Battery and Range: All U.S. A6 e-trons use a 94.4-kWh battery. The rear-wheel-drive (RWD) A6 e-tron with the Ultra package and 19-inch wheels offers an EPA-estimated range of 392 miles, making it the longest all-electric range in Audi's current lineup. The standard RWD model is anticipated to achieve around 370 miles.
- Charging Capability: The A6 e-tron features an 800-volt architecture, allowing for a peak charging rate of 270 kilowatts. Audi claims a 10-80% recharge can take as little as 21 minutes with a sufficiently potent power source. For Level 2 charging, a 9.6-kW onboard recharger is included.
- Performance: While the A6 e-tron might not offer the immediate "spark" of some high-performance EVs according to some initial reviews, its electric powertrain provides smooth, quiet, and rapid acceleration. Specific horsepower and torque figures for the U.S. market are forthcoming, but the e-tron is positioned as a highly competent electric luxury sedan.
Fuel Economy and Operating Cost
The 2025 Audi A6 gasoline models are expected to maintain similar fuel economy figures to the prior model year, as detailed by the EPA. While specific 2025 EPA estimates are pending, for context, the V6-powered A6 historically returns around 25 mpg combined.
For the A6 Allroad, the EPA-estimated fuel economy is 22 mpg city and 30 mpg highway. Given its 4,486-pound curb weight and all-wheel-drive system, this is considered a decent fuel economy for its class.
For electric models like the A6 e-tron, operating costs are primarily tied to electricity prices. Given its extensive range and fast charging capabilities, the A6 e-tron aims to offer a competitive cost-per-mile for electric vehicle ownership, potentially representing a very efficient choice for those with access to favorable charging rates.
