Southampton Audi The Audi TT Roadster 2.0 TDI quattro Powerful performance, maximum efficiency

The new 2.0 itre four-cylinder diesel delivers dynamic thrust, with a power output of 125 kW (172PS) and 350 Nm of torque. Yet at the same time the TT Roadster consumes on average only around 51.4 mpg (5.5 litres of fuel per 100 km) – a previously unequalled low figure in the sports car segment.

The new common rail injection system is equipped with state-of-the-art piezo injectors. Its eight-hole injectors can achieve up to five separate injection events every combustion cycle.

The 2.0 TDI in the Audi TT Roadster delivers 125 kW (172PS) at 4,200 rpm and sends a full 350 Nm of torque to the crankshaft at engine speeds between 1,750 rpm and 2,500 rpm. Operating quietly and generating little in the way of vibration, this model delivers a hefty amount of power from the lowest engine speeds, and is highly responsive to input from the accelerator pedal.

The superb power build-up of this engine lends it its own unique, fascinating character – that of a muscular, smart sports engine. The Audi TT Roadster 2.0 TDI quattro comfortably leaves its petrol-engined competitors behind in the mid-range spurt. It completes the sprint from zero to 62 mph in just 7.6 seconds and a top speed of 138 mph.
