Mercedes hasn't given up on the (electric) sedan:

Mercedes has only released limited technical details, but it is clear that the EQXX is short and svelte by the brand's standards. There is no word on overall length, but confirmation of a 110.0-inch wheelbase suggests it will be a little longer than the A-class sedan, which has 107.4 inches between its axles and a shorter rear overhang. The ultra-slippery shape is responsible for a claimed drag coefficient of just 0.17.

 

The aero effort contributes to significant efficiency:

The wind-cheating shape plays a large part in Mercedes's claimed powertrain efficiency, with the official release saying the car can travel six miles on just 1.0 kWh of electrical energy, a figure equivalent to a combustion car capable of 202 mpg (which is close to the efficiency that Mercedes describes as "the golden figure of one liter per 100 kilometers"). The comparison is complicated by the fact that, according to Mercedes, the EQXX's driveline is 95 percent efficient. Even the most efficient gasoline engines struggle to do better than 35 percent. This is why the EQXX can put up a big range number without a massive battery pack, Mercedes claiming that EQXX has slightly less than 100 kWh of usable capacity.
