2.5 TDI 88 kW


At the 1989 IAA Frankfurt Motor Show, Audi exhibited a milestone in automotive technology: a 2.5-liter five-cylinder direct injection turbocharged diesel with fully electronic engine management – the first of its kind in the world, and the first TDI. It had a distributor-type fuel injection pump that could build up a maximum pressure of 900 bar. The power output of this five-cylinder TDI was initially 88 kW (120 hp), and its maximum torque 265 Nm (195.45 lb-ft). From 1994 on, after further development work on the injection pump and exhaust gas recirculation, the engine’s output went up to 103 kW (140 hp). In this form it was installed in the A6, with an 85 kW (115 hp) version as an alternative.
