Fuel gauges aren't perfectly linear and the low-fuel light comes on with a few gallons still in the tank, so plan your stop before the last eighth.
At 23.8 gallons, the A8's largest tank ranks second of the seven 2016 sedans compared here. The Porsche Panamera carries the most (26.4 gal) and the Lincoln MKS the least (19.0 gal).
Other 2016 sedans of a similar size, one model per brand.
