1.9 TDI 81 kW
Audi revised the design of the 1.9 TDI in 1995. Power output went up to 81 kW (110 hp) and maximum torque to 225 Nm (165.95 lb-ft), reached now at only 1,700 rpm and remaining constant until 3,000 rpm. The key to this was a variable turbine geometry (VTG) exhaust-driven turbocharger. This powerful four-cylinder TDI was installed in the A4 and A6, and also in the A3 that was launched in 1996.
