The Audi A6 Avant isn’t necessarily the most awesome model that the German automaker offers, but it is one of just a handful of luxury wagons available on the market. However, when Audi introduced the new 3.0 Biturbo engine with 313 horsepower and 479 pound-feet of torque, which affords it a 5.3-second 0-to-100 km/h (62 mph) sprint and a 155 mph top speed, we couldn’t help but take notice.
Apparently, Senner Tuning took notice too, as it just introduced a tuning package for the A6 Avant 3.0 TDI Biturbo that takes the A6 Avant to a new level. The tuner installed its Stage 2 tuning kit for the 3.0 TDI Biturbo engine, a sport air filter and a power convertor for the drive-by-wire system to help boost its output to 374 horsepower and 572 pound-feet of torque. Though Senner did not disclose the performance numbers of this retuned A6 Avant, we estimate it at 5 seconds to 100 km/h (62 mph) and a top speed of 180 mph.
With this boost in power, Senner also chose to increase its adhesion to the road. It started off by installing a KW Street Comfort coil-over kit that drops the A6’s ride height by 30 to 55 mm (1.18 to 2.16 inches). Senner also gives buyers the choice of two 9.5-by-20-inch wheels — Varianza T1S or Sword SC1 — with high-gloss black on the faces and high-gloss anodized beads. The rims are wrapped in 255/35R20 Vredestein Ultrac Sessanta rubber.
Other than the custom wheels and the lowering kit, the A6 ’s exterior remains unchanged, making this the perfect sleeper kit for any owner.
