A unique feature of the A6 TDI is the fact that it totes piezo injectors for its third generation common-rail diesel setup. The aforementioned setup includes a common rail system that has one high-pressure pump and one rail per cylinder bank, allowing boost pressure (and, by extension, power output) to increase nearly 30-40 percent more than previous common rail systems.
With Audi's new TDI technology, the number of injection processes per combustion cycles can thus be varied almost at will. The 3.0 V6 TDI engine, for example, has up to five injection processes: in addition to the main injection process, double pilot injection takes place at the lower end of the speed range and single pilot injection in the medium speed range. On top of this, single post-injection takes place up to around 2,500 rpm and at maximum part-load. This reduces emissions and ensures a smoother combustion process.
With the A6 sedan, the V6 3.0 liter TDI engine develops 225 bhp and 450 Nm of torque. 0-100 kph time is just 7.3 seconds and top speed is 243 kmh. Despite higher power output and larger engine displacement, its consumption is still impressive at 12 kms per liter of diesel fuel (based on in-house extra urban driving cycle testing). Audi also leads the way as a luxury automobile with a low operating cost. Oil and filter changes are also significantly reduced all contributing to lesser environmental impact.
The turbocharger built into the TDI engine optimizes the charging of the combustion chambers and makes the most out of the space available in the engine. Two intercoolers that run parallel lower the temperature of the air within the engine to improve efficiency of the engine and lowering the emissions of the car.
With Audi's high performance character, comfort and safety never take a passenger seat. The A6's ESP (Electronic Stability Program) assures you of precise steering and braking especially in adverse driving situations. The Audi chassis design provides comfort and stability when driven dynamically. Two-stage, full-size front air bags and active head restraints compliment its array of already impressive safety features. The A6 sedan comes with Quattro permanent all-wheel drive that results in perfect traction in even in adverse driving conditions.
Functional design and high-quality materials in the interior maximize comfort for the occupants. Luxurious leather upholstery, premium sound system and automatic air conditioning ensure that you travel in style and luxury.
