2014 Audi A8 L 3.0 TDI Diesel (3.0L 6-cyl. Turbo Diesel AWD 8-Speed Automatic)

Driven On 8/15/2013

Ratings Summary

The Audi A8 L 3.0 TDI delivers the high levels of performance and comfort expected of a flagship luxury sedan, and enjoys the unique position of being the most fuel efficient, without any significant drawbacks. It is generously appointed, with a long list of cutting-edge options to please a wide range of tastes.
A
Performance With potent acceleration, competent braking and athletic handling, it's easy to forget that this diesel-powered A8 L is also economical. The A8 is so confidence-inspiring, it borders on sporty, yet it delivers appropriate levels of luxury.
Acceleration
B
The 3.0-liter turbodiesel makes 240 hp and 406 lb-ft of torque and gets the A8 L TDI to 60 mph in 6.3 seconds. Shifts from the 8-speed automatic are almost seamless. No diesel clatter, but not a pleasant engine note.
Braking
A
Needing only 109 feet to stop from 60 mph, the A8 's brakes instill the kind of confidence you find in some sports cars. The pedal remains predicatable in all conditions.
Steering
A
From feather-light to sporty-firm, the driver-selectable steering is precise and responsive. The A8's electric steering instills confidence and is one of the best systems available. null
Handling
A
The no-cost option summer tires supply impressive grip, with exceptional handling up to its high limits. All-wheel-drive makes it even more surefooted in the curves.
Driveability
A
Despite its large size and luxurious ride quality, the A8 is as composed and responsive as a much smaller car. Auto start/stop is quick to react, but its shudder can be jarring.
A
Comfort The standard A8 is already incredibly comfortable, with a quiet and calm cabin, well-shaped seats and a smooth ride quality. The A8 L's added rear seat space and optional indulgences make it very competitive with other luxury flagships.
Seating Comfort
A
The optional 22-way adjustable front seats with ventilation and massage should be comfortable for anybody in any condition. All seats are supportive and appropriately cushioned. Heated seats are standard.
Ride Comfort
A
The vast majority of road imperfections are easily smoothed over in comfort mode without feeling floaty or disconnected. Even after several hours, there's little driver fatigue.
Quietness
A
Wind noise is nearly absent and road noise is just barely detectable. The A8 L is one of the quietest cars available with no hint of diesel clatter.
A
Interior Cabin space and amenities are excellent with a modern and austere design that is sure to please more discerning passengers. Points are deducted for the infotainment system's complexity and the trunk that is smaller than rivals'.
Ergonomics
A
Like similarly complex systems, Audi's infotainment controller and button-rich dash take some getting used to. Voice commands and finger-tip "drawing" pad are very good.
Ingress/Egress
A
All doors are generously sized for easy access and require very little crouching. Larger rear doors sometimes problematic in tight side-by-side parking stalls, however.
Space/Room
A
The L's added 5 in. of wheelbase is noticeable inside. Rear passengers enjoy more legroom than the already spacious front seats. There's enough room for 5 adults to be comfortable.
Visibility
A
Optional top-view camera and blindspot monitors enhance the standard adaptive headlights, rearview camera and parking sensors. Rear visibility low due to high trunk lid.
Cargo/Storage
B
Trunk capacity of 13.2 cu-ft is smaller than rivals, but big enough for a few golf bags. There are plenty of interior storage pockets and bins, though none are particularly large.

A
Value Like other luxury sedans, the A8 L TDI makes use of top-notch materials and quality craftsmanship. The fuel efficient diesel engine could save you hundreds per year over gasoline-powered cars.
Build Quality (vs. $)
A
Audi's reputation for high quality is as solid as any other luxury brand's. The A8 L should meet or exceed the typical flagship sedan shopper's high expectations.
Features(vs. $)
A
The A8 L's list of standard features includes navigation, heated seats, leather, rearview camera, parking sensors, four-zone climate control and everything else you'd expect at this level.
Cost
A
The A8 L TDI's $82,500 MSRP is a relative bargain among luxury sedans undercutting the Mercedes S350 by about $10,000. It represents a steal among the other fuel-efficient rivals and has the MPG to back it up. null
MPG
A
EPA estimated 24 city/36 hwy and 28 mpg combined make the A8 L TDI the most efficient car in the segment, confirmed by the 28 mpg average on our evaluation loop. Range is 800+ mi.
Warranty
B
Basic and Powertrain warranties stand at 4 years/50,000 miles. These are average terms, but not outstanding.
Ownership
B
Roadside assistance is covered for 4 years/unlimited miles and only the first scheduled maintenance visit is free. You may purchase additional maintenance terms.
A
Fun To Drive The A8 L TDI is a luxurious tourer and technological marvel all in one beautifully understated package. Driver and passengers alike will find it very satisfying.
Driving Experience
A
With selectable comfort and dynamic drive settings that actually work as intended, the A8 L is equally adept and gratifying at shuttling VIPs as it is on twisting roads.
Personality
A
Subtle aggression lurking beneath a taut, austere exterior, the A8 is modern and sophisticated. High levels of performance and functionality make it one of the best luxury sedans.
