Powertrain & Engine Architecture
The heart of the A8 60 TDI V8 is the CVXB engine, a 4.0-liter turbocharged diesel V8. This engine utilizes a sophisticated diesel commonrail fuel injection system and a bi-turbocharger setup with an intercooler to deliver substantial power and torque. The engine produces 435 horsepower at 3750-4750 rpm and a massive 900 Nm (663.81 lb.-ft.) of torque between 1250-3250 rpm. The high compression ratio of 16:1 contributes to the engine’s efficiency. Crucially, this engine incorporates a 48-volt mild hybrid system. This system features a belt-driven starter-generator (BSG) and a small lithium-ion battery, enabling functions like extended engine-off coasting, regenerative braking, and a smoother start-stop system. The transmission is an eight-speed tiptronic automatic, known for its smooth and responsive shifts. This transmission is specifically tuned to handle the high torque output of the V8 diesel.
Driving Characteristics
The A8 60 TDI V8 offers a remarkably refined driving experience. The abundant torque available from low engine speeds provides effortless acceleration, making it ideal for both city driving and high-speed cruising. The 0-60 mph sprint takes approximately 4.2 seconds, and the electronically limited top speed of 155 mph is easily achievable. The eight-speed tiptronic transmission contributes to this performance with quick and seamless gear changes. Compared to lower-powered A8 variants, such as the 3.0-liter TDI, the 60 TDI V8 delivers a significantly more potent and engaging driving experience. While the 3.0 TDI prioritizes fuel economy, the V8 focuses on providing a luxurious and powerful ride. The quattro all-wheel-drive system ensures excellent traction and stability in all weather conditions.
Equipment & Trim Levels
The A8 60 TDI V8 typically came well-equipped with standard features including leather upholstery, a panoramic sunroof, a premium sound system, and a comprehensive suite of driver-assistance systems. The interior featured Audi’s dual-touchscreen MMI infotainment system, controlling navigation, climate control, and vehicle settings. Optional extras included massaging seats, a rear-seat entertainment system, and various customization options for interior trim and exterior paint. The trim level generally sat at the higher end of the A8 spectrum, often including features like adaptive air suspension and matrix LED headlights as standard.
Chassis & Braking
The A8 60 TDI V8 utilizes an independent multi-link suspension system at both the front and rear, enhanced by adaptive air suspension. This system provides a comfortable ride while also offering adjustable ride height and damping settings. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Additional safety features include ABS, electronic stability control, and optional 4-wheel steering, which enhances maneuverability at low speeds and stability at high speeds.
Market Reception & Comparison
The A8 60 TDI V8 was generally well-received by automotive critics, who praised its powerful engine, refined ride, and luxurious interior. However, some reviewers noted that the diesel engine, while potent, didn’t offer the same level of prestige as a comparable gasoline-powered V8. Compared to other A8 trims, the 60 TDI V8 offered a compelling balance of performance and efficiency. While the 3.0 TDI provided better fuel economy, the V8 delivered significantly more power and a more engaging driving experience. The V8 also offered a more competitive alternative to similar luxury sedans from BMW and Mercedes-Benz.
Legacy
The Audi A8 (D5) 60 TDI V8 represents a high point in diesel-powered luxury sedans. The CVXB engine, while complex, has proven to be relatively reliable when properly maintained. The mild hybrid system adds a layer of efficiency and refinement. On the used car market, these models hold their value well due to their performance and luxurious features. However, potential buyers should be aware of the higher maintenance costs associated with a complex diesel engine and the potential for issues with the emissions control system. Overall, the A8 60 TDI V8 remains a desirable and capable luxury sedan for those seeking a blend of power, efficiency, and sophistication.
