INTRODUCTION
The Audi TT Roadster (8J, facelift) 2.0 TDI quattro S tronic, produced from 2010 to 2014, represents a significant iteration of Audi’s iconic sports car. Built on the 8J platform – shared with the Volkswagen Golf Mk5 and Audi A3 – the facelift brought revised styling, improved efficiency, and updated technology. This particular variant combined the practicality of a diesel engine with the all-weather confidence of Audi’s quattro all-wheel-drive system and the convenience of the S tronic dual-clutch transmission. It aimed to broaden the TT Roadster’s appeal beyond the purely performance-focused buyer, offering a more refined and economical driving experience.
Powertrain & Engine Architecture
At the heart of the 2.0 TDI quattro S tronic lies the CFGB engine code, a 1968cc inline-four cylinder diesel engine. This engine utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. A turbocharger with an intercooler further enhances performance, boosting power and torque. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, contributing to its efficient operation. The high compression ratio of 16.5:1 is typical for diesel engines, maximizing energy extraction from the fuel. The S tronic transmission is a six-speed dual-clutch unit, offering rapid and seamless gear changes. This transmission operates with two separate clutches, pre-selecting the next gear for near-instantaneous shifts, enhancing both performance and fuel efficiency.
Driving Characteristics
The 170 horsepower and 350 Nm (258 lb-ft) of torque produced by the 2.0 TDI engine provide a respectable level of performance for a roadster. While not as overtly sporty as the petrol-powered TT models, the diesel offers strong low-end and mid-range grunt, making it well-suited for everyday driving and overtaking maneuvers. The S tronic transmission contributes to a smooth and responsive driving experience. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 7.6 seconds. The quattro all-wheel-drive system provides excellent traction, particularly in adverse weather conditions, enhancing stability and confidence. Compared to the manual transmission versions of the 2.0 TDI, the S tronic offers quicker acceleration and a more effortless driving experience, though some purists might miss the engagement of a manual gearbox. The gear ratios are tuned for a balance between performance and fuel economy, prioritizing usability over outright speed.
Equipment & Trim Levels
The 2.0 TDI quattro S tronic typically came equipped with a generous level of standard features. Interior appointments included sports seats upholstered in a combination of cloth and leather, a leather-wrapped multi-function steering wheel, and aluminum trim accents. Standard equipment also included automatic climate control, a CD stereo system with auxiliary input, and electric windows and mirrors. Optional extras included navigation system, Bose sound system, heated seats, and parking sensors. The TT Roadster’s interior design was known for its minimalist and driver-focused layout, emphasizing a sporty and modern aesthetic.
Chassis & Braking
The TT Roadster’s chassis features an independent McPherson strut suspension at the front and a multi-link suspension at the rear, providing a comfortable yet controlled ride. Stabilizer bars are fitted to both axles to reduce body roll during cornering. Braking duties are handled by ventilated discs at the front and solid discs at the rear, providing ample stopping power. The anti-lock braking system (ABS) is standard, enhancing safety and stability. The weight distribution is well-balanced, contributing to the car’s agile handling characteristics.
Market Reception & Comparison
The Audi TT Roadster 2.0 TDI quattro S tronic was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and all-weather capability. Compared to the 2.0 TFSI petrol models, the TDI offered significantly better fuel economy, making it a more practical choice for drivers covering long distances. However, the petrol engines provided more exhilarating performance and a more engaging driving experience. The 1.8 TFSI models offered a compromise between performance and economy, while the higher-output 2.0 TFSI and 3.2 V6 models catered to those prioritizing outright speed. The TDI’s reliability was generally considered good, although diesel engines can be more susceptible to issues with the particulate filter and fuel injection system.
Legacy
The Audi TT Roadster 2.0 TDI quattro S tronic has proven to be a relatively reliable and durable vehicle. The CFGB engine, while not without its potential issues, is generally considered robust when properly maintained. On the used car market, these models represent a good value proposition, offering a stylish and well-equipped roadster at a reasonable price. The combination of all-wheel drive, automatic transmission, and diesel efficiency continues to appeal to buyers seeking a practical and enjoyable open-top driving experience. Regular maintenance, including timely servicing of the diesel particulate filter, is crucial to ensure the long-term reliability of this powertrain.
