As we can see from the chart above, the 2018 BMW 640i Gran Coupe and the 2018 Audi A8 L have quite a bit in common. Both are set with the same size engine and exactly the same transmission. Drivers will notice that the Audi A8 is slightly more powerful, but the BMW 640i is slightly more efficient. One notable difference is that the BMW 6 Series offers a free maintenance warranty for 36 months or 36,000 miles, whereas the Audi A8 offers it for 12 months or 10,000 miles.

Those who choose the BMW will notice there is slightly more room for the drive and front seat passenger to stretch out their legs. However, rear seat passengers will have more space in the Audi. As noted above, the BMW offers a more convenient, flexible rear seating option that allows for more storage options. In the trunk, drivers will find 16.2 cubic feet in the BMW and 14.2 cubic feet in the Audi. Both vehicles are set standard with cruise control, leather-wrapped steering wheels and heated front seats. The BMW comes out on top with standard AUX ports, in-vehicle assistance service and stolen vehicle tracking, which are not available on the A8.
