Audi A6 2.0 TDI
Driving pleasure and economy, refinement and environmental care: the important four-cylinder TDI version is now also available in combination with the 6-speed manual gearbox.
The 2.0 TDI four-cylinder version with unit injector, one of the most modern engines in its class, made its debut in the executive class as a very talented all-rounder.
Again, the particular strength of this engine is its high output and powerful torque, combined with equally impressive economy. The Audi A6 2.0 TDI is able to easily cover a range of more than 1,100 kilometres on one single tank of diesel.
A maximum output of 103 kW (140 bhp) and peak torque of 320 Nm, available all the way between 1,750 and 2,500 rpm, make this the most powerful and dynamic four-cylinder diesel featured by Audi so far. Performance on the road is correspondingly impressive: the 2.0 TDI with 6-speed manual gearbox accelerates to 100 km/h in just 10.3 seconds and continues on up rapidly to its top speed of 210 km/h.
Two other key strengths of the 2.0 TDI are low fuel consumption - 6.0 litres of diesel fuel per 100 km (overall value) - as well as compliance with the EU4 emissions standard.
And last but certainly not least, the four-cylinder unit gives the new Audi A6 a standard of smoothness and refinement which certainly befits a luxury saloon of this calibre. The balance shaft module with two shafts rotating in opposite directions, for example, helps to reduce engine vibration to an absolute minimum particularly at high engine speeds, with second-order vibrations being reduced by more than 80 percent.
New engine/transmission versions in the Audi A6
The Audi A6 2.4 is now also available with the multitronic continuously variable automatic transmission, a transmission that combines the advantages of manual gearbox and geared automatic. Fortes typical of multitronic are smooth but very dynamic acceleration as well as convenient operation and the efficient transmission of power.
The high standard of operating convenience offered by multitronic exceeds that of a conventional converter-type automatic transmission, while in terms of dynamic performance and economy, multitronic can by all means be compared with a manual gearbox. And if drivers wish to actively choose the appropriate transmission ratio, they are able to do so conveniently by means of paddles on the steering wheel - now providing no less than seven predefined speeds.
Modified for the new Audi A6, the multitronic variator spans an even wider range of gear ratios: the overall ratio between the largest and the smallest gear transmission ratio is now 6.25, virtually ideal for such a transmission. It permits dynamic, sports-style acceleration thanks to the use of lower ratios, but also fully exploits the engine's economy potential by using the highest ratio.
A brand-new multitronic function in the Audi A6 is the starting assist function: a simple press of the brake pedal and the service brake automatically prevents the car from rolling back on a gradient. It is also released automatically as soon as the driver opens the throttle to pull away again.
With a power output of 130 kW (177 bhp) and a maximum torque of 230 Nm between 3,000 and 5,000 rpm, this new model version accelerates from 0 to 100 km/h in 9.2 seconds. It goes on to reach a top speed of 226 km/h and achieves an overall fuel consumption of 9.6 litres of premium grade fuel (95 RON) per 100 kilometres under standard conditions.
The A6 3.2 FSI quattro with 6-speed manual gearbox is also a new addition to the range. quattro permanent four-wheel drive is a typical feature of all high-performance Audi models. It ensures excellent traction and stable cornering, and minimises the effect of propulsive forces on the car's self-steering properties. This is a precondition for a high level of dynamic stability and high cornering speeds.
A Torsen differential in the new Audi A6 - with its longitudinally installed engines - automatically ensures the optimum distribution of power between all four wheels. The name "Torsen" is a contraction of the two terms "torque" and "sensing". The Torsen differential is a self-locking worm gear.
The advantage is that the locking action is only prompted by the driveline. Yet this type of differential accommodates differences in speed when the brakes are applied and when cornering. Normally the power is split 50:50 between the two pairs of wheels, but in extreme cases 75 percent of propulsive power can be diverted to either pair.
With a power output of 188 kW (255 bhp) and a maximum torque of 330 Nm at 3,250, the A6 3.2 FSI quattro accelerates from 0 to 100 km/h in 6.8 seconds and continues on up to a governed top speed of 250 km/h. This model's overall fuel consumption under standard conditions is 10.9 litres of premium grade fuel (98 RON) per 100 kilometres.
