The Audi A8 L (D4, 4H facelift) 3.0 TFSI quattro tiptronic, produced from 2013 to 2017, represents a sophisticated blend of luxury, performance, and technology within the flagship A8 range. This long-wheelbase (L) variant, built on the Volkswagen Group’s D4 platform (also underpinning the Bentley Continental GT and Porsche Panamera), was specifically designed to appeal to buyers prioritizing rear passenger comfort and a refined driving experience. The 3.0 TFSI engine, a supercharged 3.0-liter V6, offered a compelling alternative to the more expensive and powerful 4.0 TFSI V8, and the tiptronic transmission provided smooth and responsive gear changes.
Powertrain & Engine Architecture
At the heart of this A8 L variant lies the EA837 evo 3.0-liter V6 engine, designated as the CREA engine code. This engine utilizes a Roots-type supercharger in conjunction with direct fuel injection and multi-port manifold injection, delivering a broad torque curve and responsive acceleration. The supercharger provides instant boost at low engine speeds, eliminating turbo lag and contributing to the engine’s smooth power delivery. The engine produces 310 horsepower at 5200-6500 rpm and 440 Nm (324.53 lb-ft) of torque between 2900-4750 rpm. The eight-speed tiptronic automatic transmission, a staple of Audi’s quattro models, features a torque converter and allows for both fully automatic operation and manual gear selection via steering wheel-mounted paddles or the gear selector. The transmission is designed to optimize fuel efficiency and provide seamless shifts.
Driving Characteristics
The 3.0 TFSI-equipped A8 L offers a composed and refined driving experience. While not as overtly sporty as the 4.0 TFSI variant, the 310 hp engine provides ample power for effortless cruising and confident overtaking. The tiptronic transmission contributes to smooth acceleration, and the quattro all-wheel-drive system ensures excellent traction in all weather conditions. The long wheelbase and air suspension contribute to a comfortable ride, effectively isolating passengers from road imperfections. Compared to the 3.0 TDI diesel, the 3.0 TFSI offers quicker acceleration and a more responsive feel, but at the expense of slightly higher fuel consumption. The gear ratios in the tiptronic transmission are tuned for both performance and efficiency, with lower gears providing brisk acceleration and higher gears optimizing fuel economy during highway cruising.
Equipment & Trim Levels
The A8 L 3.0 TFSI quattro tiptronic came generously equipped as standard. Typical features included leather upholstery, heated and ventilated front seats with massage function, a premium sound system, a navigation system with MMI touch response, adaptive cruise control, and a panoramic sunroof. Optional extras included upgraded leather packages, rear-seat entertainment systems, a head-up display, and advanced driver-assistance systems such as night vision and lane keep assist. Trim levels varied slightly by market, but generally offered options for enhanced interior trim materials and exterior styling elements.
Chassis & Braking
The A8 L’s chassis features an independent multi-link suspension at the front and an independent trapezoidal lever suspension at the rear, both incorporating air suspension as standard. This air suspension system allows for adjustable ride height and damping, further enhancing ride comfort and handling. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard safety features. The A8 L’s steering utilizes an electric power steering system, offering precise and responsive control.
Market Reception & Comparison
The A8 L 3.0 TFSI quattro tiptronic was generally well-received by automotive critics. It was praised for its refined driving experience, luxurious interior, and advanced technology. Critics noted that the 3.0 TFSI engine provided a good balance between performance and fuel economy, making it a practical choice for buyers who didn’t require the outright power of the 4.0 TFSI. Compared to the 3.0 TDI, the petrol engine was favored for its smoother operation and quicker response, although the diesel offered superior fuel efficiency. Reliability reports suggest that the EA837 engine is generally robust, although preventative maintenance, particularly regarding the supercharger, is crucial.
Legacy
The Audi A8 L (D4, 4H facelift) 3.0 TFSI quattro tiptronic remains a desirable luxury sedan in the used car market. Its combination of comfort, technology, and performance continues to appeal to buyers seeking a sophisticated and refined driving experience. The EA837 engine, while requiring regular maintenance, has proven to be relatively reliable. However, potential buyers should be aware of the potential for carbon buildup on the intake valves, a common issue with direct-injection engines. Overall, this A8 L variant represents a well-engineered and luxurious vehicle that continues to offer a compelling value proposition in the used car market.
