Public debut penciled in for Paris.
Audi has unveiled a series of midcycle upgrades for the fourth-generation A6, with the complete range benefiting from subtle styling tweaks, as well as new engines, transmissions and infotainment system. The changes affect the A6, S6, A6 Avant, A6 Allroad and range-topping RS6 Avant. Visual updates are modest in the extreme, with a few sharpened creases, a more rigid grille, refined headlights and redesigned exhaust pipes.
Turn signals receive Audi’s dynamic LED feature, while inside a more advanced infotainment system joins some new color combos. Electronic driver aids have also been updated, including adaptive cruise control with stop & go traffic crawling, enhanced night vision, and optional head-up display. Important changes to the powerplants see all three TFSI and TDI engines becoming EU6 emission compliant. Two “Ultra” models have joined the A6 lineup, featuring aerodynamic enhancements and suspensions with glass fiber-reinforced polymer (GFRP) springs, as part of a series of weight saving measures.
The 1.8-liter TFSI boasts 41.3 mpg, while a 2.0-liter TDI comes with 150 hp and 56 mpg. Both are mated to a newly-developed S tronic transmission. Other engines on offer in the A6 range include an updated 3.0 TDI clean diesel unit with either 218 hp or 272 hp, while a twin-turbo variant delivers 320 hp and 326 hp in the 3.0 TDI competition. The S6/S6 Avant comes with a 4.0-liter TFSI twin-turbo V8 rated at 450 hp, enabling the sedan to hit 62 mph in 4.4 seconds, while the RS6 Avant generates 560 hp and clocks 0-62 mph in just 3.9 seconds en route to a 190 mph top speed. Both sporty models come standard with quattro all-wheel drive. After debuting in Paris next month, the 2015 Audi A6 will go on sale in Europe.
