History:

The Audi V8 (Typ 4C) is a full-size, four-door luxury sedan, built by Audi in Germany from 1988 to 1993 as the company’s flagship model. It was the first Audi car to use a V8 engine, and also the first Audi to combine a quattro system with an automatic transmission. Early cars used 3.6-liter V8s, while later cars featured a 4.2-liter version of the engine. The Audi V8 was replaced by the Audi A8 in 1994, although the A8 was not sold in North America until 1996. The Audi V8 competition model won two consecutive Deutsche Tourenwagen Meisterschaft titles in 1990 and 1991, with the championship winners being Hans-Joachim Stuck and Frank Biela respectively. Audi was the first company to win back-to-back DTM titles.

Engines:

Both available engines used a fully electronic Bosch Motronic engine control unit (ECU), with selective cylinder bank knock control, dual-body throttle valve, lambda mixture control via air volume metering intake and exhaust gas temperature sensor, and unleaded gasoline required. Fuel was routed to the combustion chambers via eight electronic fuel injectors located in the intake manifold, fed by two common fuel rails (one per cylinder bank), and were sequentially “ pulled ” or activated in accordance with engine firing order. While the 3.6 V8 was able to use 95 RON (91 AKI) fuel, for the 4.2 V8 the more expensive 98 RON (93 AKI) unleaded “SuperPlus” was required to achieve the stated horsepower. [15] The use of 95 RON in the 4.2 V8 resulted in lower power output, as well as increased fuel consumption.

When the Audi V8 was originally launched, the only offering was the 3.6-liter engine, which displaced 3,562 cubic centimeters (217.4 cubic inches). This V8 engine complied with the DIN standard with a maximum engine power of 184 kilowatts (250 PS; 247 hp) at 5,800 revolutions per minute (rpm), and generated a torque rotational force of 340 newton meters (251 lbf⋅ft) at 4000 rpm. In August 1991, Audi introduced a 4.2-liter engine, displacing 4,172 cubic centimeters (254.6 cubic inches), to complete the choice of the existing 3.6-liter V8. This shared many components of the 3.6 V8, and the 4.2 unit was identical to the optional V8 used in the Audi S4 (aka Ur-S4), sharing the same rated outputs and the same ABH ID code. Like the 3.6 V8 model, the existing four-speed automatic transmission remained available. However, a new six-speed manual replaced the five-speed manual. This powertrain is identified by chrome ” V8 ” badges on the radiator grille and on the trunk lid, where in some cars also the badge “4.2 quattro ” is present.
