2018 Audi A8 55 TFSI Quattro – Powerful Luxury Sedan 340 hp, 500 Nm. 2018 Audi A8 55 TFSI Quattro – Drive, Interior and Exterior.
The luxury sedan comes with a three-liter diesel unit in the Audi A8 50 TDI quattro, while the Audi A8 55 TFSI quattro features a V6 gasoline engine. The A8 is the first production model to feature the brand’s new type designation clearly at the rear. The reference value for the double-digit number combination is the power output of the individual model in kilowatts. The numeral combinations increase in increments comprising five designations each, and they represent the hierarchy within both the respective model ranges and the brand’s overall model portfolio. Thus the numeral combination “50” will in future appear on the back of those models which deliver between 210 and 230 kW of power; “55” stands for the power output range between 245 and 275 kW. This new system will allow Audi to standardize the type designations for its worldwide range of automobiles.
