From the aerodynamic perspective, the E-Class is one of the slipperiest sedans extant. Its 0.27 coefficient of drag is a benchmark for sedans and helps minimize wind noise and maximize fuel economy.
The E-Class wagon, available only in E350 and E63 AMG versions, will never be mistaken for anything but a wagon. Nonetheless, it is impressively sleek, and some critics find the tear-drop taper of the rear roof more aesthetically pleasing than the trunk deck on the sedans. Certainly, the wagon's added cargo-passenger flexibility is welcome. If the E350 wagon is too stodgy for your taste, there's always the E63 AMG version.
The E63 AMG sedan and wagon look meaner than the other E-Class cars. With their lower body cladding and 18-inch wheels, the E63s look racy and aggressive. As is often the case, the body add-ons add slightly more drag, if you can call a super slippery 0.28 Cd more drag. The aerodynamic aids are for downforce, to improve grip in fast corners. Next Page
