Audi TDI quattro (1994)
In the first A6, launched in 1994, Audi fitted a further development of the five-cylinder TDI; its power output rose to 103 kW (140 hp), its torque to 290 Nm (213.89 lb-ft). A six-speed transmission was standard, permanent all-wheel drive an option. With a top speed of 208 km/h (129.25 mph) and 9.9 seconds for the sprint from 0 to 100 km/h (62.14 mph), the first TDI quattro raised the bar to a new level. The engine became legendary with the TV commercial which asked the question “Where’s the tank?” It was able to cover distances of up to 1,300 kilometers (808 miles) on one tank of fuel.
