Senner Tuning’s team of professionals have created a power upgrade program for the 3.0-litre V6 TDI version Audi A7 Sportback.
The car’s standard output was increased from 245 HP (180 kW) and 500 Nm of torque to 306 HP (225 kW) and 620 Nm of maximum torque, and as a result its top speed has also been dialed up at 280 Km/h (174 mph). 
Apart from increasing performance, Senner Tuning has also fitted the Audi A7 Sportback with a stainless steel exhaust system featuring two 90 mm tailpipes, along with a power converter for the electric gas pedal and a 30 mm lowered suspension.
The Senner Audi A7 sits on 20 inch Varianza T1S black polish rims wrapped in Vredestein Ultrac Sessanta tires (size 275/35R20).
