Audi A8 Available With Two New TDI Engines in Australia

The A8, Audi’s most technologically advanced car ever built, is proving popular with Australian customers. That’s why the German carmaker’s Australian division has launched a pair of frugal TDI diesel engines. Joining the existing 4.2-liter FSI naturally aspirated V8 will be a six-cylinder 3.0 TDI and the V8 4.2-liter turbocharged oil burner.

The new 3.0 TDI is equipped as standard with a start-stop system that cuts the engine when the luxury sedan top at a traffic light or an intersection and the driver keeps the brake depressed. In the standard Australian driving cycle, the new system alone reduces fuel consumption by 0.4 litres/100 km and reduces emissions by around 8 grams of CO2/km. The V6 diesel accelerates the new Audi A8 from zero to 100 km/h (62 mph) in 6.6 seconds and on to a governed top speed of 250 km/h (155 mph).

The 4.2-liter TDI offers even better acceleration, pushing the large executive car to a 100 km/h (62 mph) in 5.5 seconds, but top speed is still electronically limited to 250 km/h (155 mph). Thanks to a revised ECU map, standard diesel consumption has dropped to only 7.6 litres/100 km, while CO2 emissions have been reduced to 199 grams per kilometer. This is 1.8 litres/100 km or 19 percent less than its predecessor. The official press release from Audi Australia states that “the Audi A8 4.2 TDI is the only V8 diesel engine in the luxury class with CO2 emissions below 200 g/km.”

“The new Audi A8 is the sportiest sedan in the segment. Now with the introduction of these two cutting-edge TDI engines, we have added a new chapter in Audi’s efficiency story and proved without doubt that the A8 is the pinnacle of the Audi range and the leader in its class,” said Audi Australia’s managing director, Uwe Hagen.
