Road Test: 2013 Audi A6 Avant 3.0 BiTDI quattro

December 17, 2012

Audi A6 Avant 3.0 BiTDI 2013_01For the new Audi A6 Avant, the 3.0-litre, V6 diesel engine is available in three variants. The basic version with 204 hp and 450 Nm provides an enjoyable performance for a big car with an acceleration from zero to 100 km/h taking 7,2 seconds. The next version with 245 hp and 580 Nm makes the A6 a performance wagon with a sprint time of 6,3 seconds. However, this third version makes the Audi A6 Avant to accelerate like a sports car.

The latest addition to the Audi’s line of V6 TDI engines has the same displacement, 2967cc as the other 3.0-litre diesels. The difference is that this new version comes with two turbochargers. The new 3.0 BiTDI, as it could be called, produces 313 horsepower and mighty 650 Newton metres of torque. These would be impressive figures for any engine, but for a 3.0-litre diesel, they are magnificent. With its new BiTDI engine, the Audi A6 Avant can sprint from zero to hundred in 5,3 seconds, while the top speed is limited to 250 km/h. All versions of the new A6 Avant regardless of the engine are equipped with the Audi drive select driving dynamics system, which allows the custom adjustment of the drivetrain, chassis and assistance systems in four modes; comfort, auto, dynamic and individual. An efficiency mode is also available in all models with forced induction.

A new feature, appearing for the first time with this 3.0 BiTDI, is an innovative sound actuator. Integrated in the exhaust system, it enhances the acoustics to a sportier level. The actuator system consists of a speaker which imposes a defined oscillation pattern on the exhaust flow and transforms the typical TDI exhaust note into a more sonorous roar that sounds more like a high-performance petrol engine than a diesel. The sportier sounds are always nice, but when you know that they are created artificially, it takes something away from the enjoyment. Works OK, but maybe we could have done without it.

Depending on the engine, the A6 Avant is available with manual, multitronic or S tronic transmission. This 3.0 BiTDI comes with a new 8-speed tiptronic automatic transmission. The eight-speed transmission improves not only performance, but also the fuel economy as the gears are widely spaced. For example at the eighth gear with the driving speed of 120 km/h, the engine revs are about 1400rpm. Fuel economy is also improved with the use of technologies, like the start-stop system, the energy recuperation and the innovative thermal management system that quickly brings the coolant and motor oil up to their operating temperatures. This makes the powerful diesel quite economical as well. The combined fuel consumption is just 6,4 l/100km and the CO2 emissions are 169 g/km. It might be a bit of a challenge to achieve consumption figures this small, but 3.0 BiTDI still easily beats the 3.0 TFSI and many other petrol engines with similar performance.

The new Audi A6 Avant measures 4.93 meters (16.17 ft) in length and 1.87 meters (6.14 ft) in width. The wheelbase has grown to 2.91 meters (9.55 ft). Although big in size, the new composite construction concept makes the body of the Audi A6 Avant unusually light, but highly rigid. The body of the A6 Avant is roughly 30 kilograms (66.14 lb) lighter than that of the previous model. Depending on the engine, the complete car is as much as 70 kilograms lighter. However, with all its features, this 3.0 BiTDI has a curb weight of almost 2,000 kilograms. If you want a more dynamic look for your new Audi A6, then you should choose the Audi S line sports package. It lowers the body by 30 millimeters (1.18 in) compared with the standard chassis, and includes large wheels, appearance modifications and many special details for the all-black interior.
