INTRODUCTION
The Audi A3 Sedan (8Y) 35 TDI S tronic, launched in 2020, is a front-wheel-drive compact sedan powered by a 2.0-liter turbocharged diesel engine. It represents a significant update to the A3 line, incorporating Audi’s latest design language and technology. This variant was specifically designed to appeal to European markets where diesel engines remain popular due to their fuel efficiency and torque characteristics. In the US market, the A3 Sedan is typically offered with gasoline engines, making the 35 TDI a primarily European specification. The ‘35 TDI’ designation indicates a mid-range diesel offering, positioned above the entry-level petrol models and below the more potent 40 TDI.
Powertrain & Engine Architecture
At the heart of the A3 35 TDI S tronic lies the DSRB 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 engine benefits from a turbocharger with an intercooler, boosting power and torque output. The engine produces 150 horsepower at 3000-4200 rpm and 360 Nm (265.52 lb-ft) of torque between 1600-2750 rpm. The S tronic transmission is a seven-speed dual-clutch transmission (DCT) known for its quick and smooth gear changes. This transmission offers both automatic and manual shifting modes, providing drivers with flexibility. The DCT contributes to improved fuel efficiency compared to traditional automatic transmissions.
Driving Characteristics
The 35 TDI S tronic offers a comfortable and refined driving experience. The engine delivers ample torque from low engine speeds, providing strong acceleration in everyday driving situations. While not a performance-oriented variant, the 8.4-second 0-62 mph acceleration is respectable for its class. The S tronic transmission shifts quickly and seamlessly, enhancing the overall driving experience. The gear ratios are tuned for fuel efficiency, with higher gears prioritizing economy during cruising. Compared to the more powerful 40 TDI, the 35 TDI feels less urgent in acceleration, but offers a more relaxed and economical driving experience. Manual versions of the A3 35 TDI offer a more engaging driving experience, but the S tronic provides convenience and efficiency for daily commutes.
Equipment & Trim Levels
The A3 35 TDI S tronic typically comes well-equipped as standard. Features include Audi’s MMI infotainment system with a touchscreen display, automatic climate control, and a suite of driver-assistance systems such as lane departure warning and automatic emergency braking. Interior upholstery is typically cloth, with leather options available as upgrades. Trim levels vary by market, but common options include upgraded alloy wheels, a panoramic sunroof, and a premium sound system. The digital cockpit, Audi’s virtual instrument cluster, is often available as an optional extra, providing customizable displays for the driver.
Chassis & Braking
The A3 35 TDI S tronic utilizes an independent McPherson strut suspension at the front and a multi-link suspension at the rear. This setup provides a good balance between ride comfort and handling. The front brakes are ventilated discs, while the rear brakes are solid discs. ABS (Anti-lock Braking System) is standard, along with electronic stability control. The suspension is tuned to prioritize comfort, but still offers decent body control during cornering. Stabilizer bars are fitted to both the front and rear axles to reduce body roll.
Market Reception & Comparison
The A3 35 TDI S tronic was generally well-received by automotive critics for its fuel efficiency, comfortable ride, and refined interior. It was often praised as a practical and economical choice for those seeking a compact executive sedan. Compared to the petrol-powered A3 variants, the 35 TDI offered significantly better fuel economy. However, some critics noted that the diesel engine could be slightly noisy compared to the smoother petrol engines. Against competitors like the BMW 1 Series and Mercedes-Benz A-Class, the A3 35 TDI S tronic held its own, offering a compelling combination of features and value.
Legacy
The Audi A3 8Y 35 TDI S tronic, while not a high-performance variant, represents a well-engineered and reliable compact sedan. The DSRB engine is known for its durability, and the S tronic transmission, while requiring regular maintenance, is generally robust. On the used car market, these models are sought after for their fuel efficiency and practicality. Regular servicing, including oil changes and timing belt replacements (where applicable), is crucial for maintaining the long-term reliability of this powertrain. As diesel technology evolves, the 35 TDI S tronic remains a relevant and capable option for those seeking an economical and comfortable compact sedan.
