Developing a large and fully electric sedan didn’t seem like a problem for BMW’s chassis engineers. The i7 weighs nearly 2.7 tons, yet delivers excellent handling. Motivation comes from a pair of electric motors producing either 536 horsepower or 650 horsepower depending on the model. A comprehensive suite of advanced technologies is part of the package, highlighted by a 31.3-inch BMW Theatre Screen that folds down from the roof, much to the delight of rear-seat passengers.
