“BMW” is hard at work at developing their i7 full-size electric luxury sedan. While we've already seen numerous spy shots of the vehicle being tested, BMW still thought it will be interesting for us to see official photos of its camouflaged prototypes playing around the snow.

In addition to a number of official photos, BMW also released a few details about the their electric flagship sedan. Apparently, the i7 is "the world’s first all-electric luxury sedan", which is a bold claim but is there some truth in BMW's statement?

Its closest competitor, the Mercedes-Benz EQS, is a full-size luxury car, but it's not technically a sedan.} With its sloping fastback-style roofline and rear hatch, the EQS is classified as a liftback. You also have cars like the Porsche Taycan and Audi e-Tron GT, which have traditional sedan trunks, but since these are less than five meters (196.85 inches) long, these are in line with the midsize Mercedes EQE.}

Lastly, the Tesla Model S also has a fastback profile and a rear hatch, which also classifies the Model S as a liftback. So in hindsight, BMW does have some truth to its claim that it's the first all-electric luxury sedan, albeit in the full-size class.}

As for its design, we still can't see through the heavily-camouflaged prototype as much as we would have hoped for. Nevertheless, its upright proportions, long hood, generous wheelbase, and traditional Hofmeister kink at the C-pillar are pretty much evident.

The BMW i7 also has a large grille, though being electric, this will mostly be closed off. And then there are the headlights, which seem to confirm the fact that they will be separate from the LED daytime running lights and are housed in a smoke panel, just like the BMW Concept XM. If you didn't like the XM's face, then sorry, you probably won't like the i7.

The BMW i7 will basically be the electric version of the upcoming 7 Series. The company says that its suspension components, steering and braking systems as well as driving dynamics, and vehicle stability systems "are designed to raise the balance between sportiness and ride comfort so typical of the brand’s luxury sedans to the next level."

As the i7 continues to undergo winter testing at the BMW Group winter test center in Arjeplog, Sweden--which is just a few kilometers from the Arctic Circle--the electric drivetrain, high-voltage battery, power electronics, and charging technology are being tested its limits. The electric drivetrain uses the brand's fifth-generation BMW eDrive technology, which the iX midsize electric crossover SUV already uses.

That's all the new details that we know so far. The i7 has been confirmed by BMW that it will be launched in 2022.
