Powertrain & Engine Architecture
The heart of the A4 Avant 2.0 TDI quattro S tronic is the DETA engine, a 2.0-liter inline-four cylinder diesel engine. This engine utilizes a common rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. The DETA engine features a turbocharger with an intercooler, enhancing power output and efficiency. The engine also incorporates a Diesel Particulate Filter (DPF) to reduce harmful emissions, meeting stringent Euro 6 standards. The valvetrain is a Dual Overhead Camshaft (DOHC) design with four valves per cylinder, contributing to efficient gas exchange. The S tronic transmission is a seven-speed dual-clutch transmission. This transmission offers rapid and smooth gear changes, enhancing both performance and fuel economy. It operates by pre-selecting the next gear, allowing for near-instantaneous shifts. The quattro all-wheel-drive system employs a self-locking center differential, distributing torque between the front and rear axles as needed, providing excellent traction in various conditions.
Driving Characteristics
The 190 hp 2.0 TDI with the S tronic transmission delivers a refined and capable driving experience. Acceleration from 0 to 60 mph takes approximately 7 seconds, and the car feels responsive in everyday driving situations. The S tronic transmission contributes to a smooth and seamless power delivery, with minimal turbo lag. Compared to the manual transmission versions, the S tronic offers greater convenience, especially in urban traffic. While not as overtly sporty as higher-output A4 variants (like those with the 2.0 TFSI gasoline engine), the 2.0 TDI provides ample power for highway cruising and overtaking. The quattro all-wheel-drive system inspires confidence in inclement weather, providing enhanced stability and grip. The gear ratios are tuned for a balance between performance and fuel efficiency, with taller gears for relaxed highway driving and shorter gears for quicker acceleration.
Equipment & Trim Levels
The A4 Avant 2.0 TDI 190 hp quattro S tronic typically came well-equipped as standard. Features included automatic climate control, a multi-function steering wheel, power windows and mirrors, and an infotainment system with a color display. Upholstery was typically cloth, with leather options available as an upgrade. Optional extras included navigation, a premium sound system, parking sensors, and advanced driver-assistance systems like adaptive cruise control and lane departure warning. Trim levels varied slightly depending on the market, but generally offered packages that bundled popular options together.
Chassis & Braking
The B9 A4 Avant features an independent multi-link suspension on both the front and rear axles, providing a comfortable and controlled ride. The suspension is tuned to balance handling and comfort, offering a good compromise for everyday driving. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock Braking System (ABS) is standard, enhancing safety and stability during braking. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Audi A4 Avant 2.0 TDI 190 hp quattro S tronic was generally well-received by automotive critics. It was praised for its refined engine, comfortable ride, and sophisticated interior. Fuel economy was a strong point, with combined figures around 52.3 US mpg. Compared to the lower-powered 1.6 TDI variants, the 2.0 TDI offered significantly more performance. However, it was more expensive to purchase and maintain. Compared to the gasoline-powered A4 models, the 2.0 TDI offered better fuel economy but slightly less outright performance. The S tronic transmission was generally favored over the manual transmission for its smoothness and convenience.
Legacy
The DETA engine and S tronic transmission combination proved to be relatively reliable, although like any modern diesel engine, it is susceptible to issues with the DPF and turbocharger if not properly maintained. Regular oil changes and the use of high-quality fuel are crucial for long-term reliability. In the used car market, the A4 Avant 2.0 TDI quattro S tronic remains a popular choice, offering a blend of practicality, performance, and refinement. Its all-wheel-drive system and comfortable interior make it a suitable option for buyers seeking a versatile and capable station wagon.
