The 3.0 TDI represents the very latest technology. The Audi bestseller in the large model series is now even cleaner and satisfies the requirements of the Euro 6 emissions standard. Performance has also increased. Output is 200 kW (272 hp), the maximum torque of 580 Nm (427.8 lb-ft) is available between 1,250 and 3,250 rpm.
The updated Audi A7 Sportback, in which the new V6 diesel is being used for the first time, accelerates with quattro all-wheel drive from 0 to 100 km/h (62.1 mph) in 5.7 seconds on its way to an electronically limited top speed of 250 km/h (155.3 mph). Fuel consumption is just 5.2 liters of fuel per 100 km (45.2 US mpg) on average, which corresponds to 136 grams of CO2 per km (218.9 g/mile). The new 3.0 TDI is thus 13 percent more efficient than the previous model.
In the ultra model, the new V6 diesel is even more efficient and delivers new best marks. With 160 kW (218 hp) and 400 Nm (295 lb-ft) of torque, it accelerates in 7.3 seconds from zero to 100 km/h (62.1 mph) and reaches a top speed of 239 km/h (148.5 mph). It consumes just 4.7 liters of fuel per 100 kilometers (50.0 US mpg), a CO2 equivalent of 122 grams per kilometer (196.3 g/mi).
The new 3.0 TDI, which works with ignition pressures of up to 180 bar, has taken over the key dimensions of the two previous generations: the bore of 83.0 millimeters (3.3 in) and the stroke of 91.4 millimeters (3.6 in) for a displacement of 2,967 cc. The cylinder banks arranged at 90 degrees to one another; a balance shift spins in the cylinder crankcase. The cylinder crankcase is made of high-strength, yet lightweight vermicular graphite cast iron. Intensive detail work has shaved some weight from it. The entire engine weighs 192 kilograms (423.3 lb).
