Frequently Asked Questions

The Mercedes-Benz E-Class edges out the A8 for highway comfort due to its lighter weight, superior fuel economy (31 mpg vs 29 mpg highway), and more nimble handling characteristics. However, the A8's full-size proportions and 38.5 inches of rear legroom provide exceptional space for rear passengers on long trips.
