The Audi A6 TDI provides power, luxury and efficiency without a hint of compromise. [FIMG=Left]http://www.cleanmpg.com/photos/data/523/14A6TDISline_01_Large.jpg[/FIMG]Bob Winger - CleanMPG - September 1, 2013 The Audi A6 model line, representing class-leading technology, performance and precision, is enhanced for the 2014 Model Year with the addition of the Audi A6 TDI clean diesel model. Performance New for the 2014 Model Year, the Audi A6 TDI achieves an impressive EPA estimated fuel economy of 24/38/29 mpgUS city/highway/combined while at the same time delivering uncompromised performance, design and luxury and easily the best fuel economy among TDI competitors in its segment. The 3.0L V6 clean diesel engine with 8-speed Tiptronic transmission and Quattro all-wheel drive generates a powerful 240 hp and 428 lb-ft torque, seamlessly launching from 0-60 MPH in 5.5 seconds. The A6 employs Audi ultra lightweight technology through aluminum body panels that reduce weight and enhance efficiency. The relatively light chassis provides the A6 driver with excellent ride quality, handling and driving dynamics. Also continuing the brand’s commitment to delivering impressive performance and improved efficiency, the A6 TDI is equipped standard with the convenient and fuel-saving start-stop efficiency system. When the driver presses the brake pedal at stoplights or in other prolonged idle situations, the engine shuts off. When the driver releases the brake pedal, the engine instantaneously starts up again. Exterior The Audi A6 features sharp lines, short overhangs, and distinctive and functional design elements – like the optional LED headlights and standard LED taillights – giving the A6 an undeniable presence on the road.

Technology and driver assistance The Audi A6 is one of Audi’s most innovative and technologically-advanced models on the road, making 2,000 decisions per second to assist the driver.

Other innovative features available in the A6 include Head-Up Display, Night Vision Assistant, and MMI touch with handwriting recognition. Audi connect The award-winning infotainment system Audi connect is standard on the A6 TDI. Audi was the first global auto manufacturer to offer factory-fitted in-vehicle Wi-Fi connectivity for passenger use, enabling the Audi connect system to deliver connectivity to up to eight wireless devices. With Audi connect – offered complementary for six months and available for as little as $15 per month thereafter – the onboard Audi MMI Navigation system is enhanced with Google Earth maps for a true aerial view of the route. Audi connect also features real-time localized weather, news and live fuel prices; Google Voice Local Search for detailed information about travel destinations, such as restaurant or hotel hours, pricing and customer reviews; and the myAudi Destination feature, which allows users to log on to Google Earth from virtually any location in the U.S. and download up to 50 destinations to the vehicle. Audi also offers real-time Sirius XM Traffic information via enhancements to the Audi MMI Navigation plus system (active Sirius XM Traffic subscription required of course).

It may seem like a contradiction for us to be describing these types of performance cars that go from 0 to 60 mph in 5.5 seconds. We typically don’t concern ourselves with acceleration performance here. I would like to think that Audi has managed to produce some exciting vehicles that can provide the exhilarating driving experience that some people demand, but still provide respectable fuel efficiency. That is no small feat of automotive engineering acumen. We are looking forward to putting this vehicle through it’s paces very shortly. ;-) 2014 Audi A6 TDI "Here's looking at you, kid" ... And what a great look too!
