2014 Audi A8: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2014 Audi A8 is the arrival of the long-wheelbase A8 L TDI diesel. The rest of the lineup receives lighter equipment updates rather than a full redesign.
About the 2014 Audi A8
3rd gen / D4 A8 (2011-2017), pre-refresh year just before the 2015 facelift.
Audi positions the A8 as a technology-led flagship sedan that mixes understated design, aluminum-intensive construction, standard quattro all-wheel drive, and a very quiet, carefully finished cabin. Compared with rivals, the A8 leans more driver-focused than showy, especially in standard-wheelbase form, while the long-wheelbase versions push farther into rear-seat comfort. The core appeal is big-sedan luxury with strong road manners, advanced cabin controls, and a broad spread of engines from efficient diesel and supercharged V6 power up to a W12.
The 2014 A8 lineup spans the shorter, more driver-focused 3.0T and 4.0T sedans and long-wheelbase versions built around rear-seat comfort. The new L TDI combines a 240-hp turbo-diesel V6 with all-wheel drive and an EPA-estimated 28 mpg combined. The 420-hp 4.0T is the understated performance model, while the 500-hp L W12 adds massaging front and rear seats and full LED headlights.
What changed, by category
Powertrain
The new long-wheelbase A8 L TDI joins the U.S. lineup with a 240-hp 3.0-liter turbo-diesel V6, an eight-speed automatic transmission, and all-wheel drive. It is rated at 24 mpg city, 36 mpg highway, and 28 mpg combined.
Tech
The regular-wheelbase 3.0T and 4.0T gain a standard advanced key system, power soft-closing doors, hands-free trunk operation, parking sensors, and a rearview camera. On the long-wheelbase L 3.0T and L 4.0T, the rearview camera is no longer standard.
