BMW Concept I4

Just as the BMW Concept 4 previewed the next-generation 4 Series when it debuted last year at Frankfurt, the new Concept i4 previews what will become the production-spec i4 in 2021. Think of it as an all-electric 4 Series Gran Coupe, and yes, it will have the big grille even though there’s no engine in need of air.

In this instance, that grille isn't just a BMW ornamental piece you either love or hate. Since it's not actually serving a normal grille function, BMW will use it as something called an "intelligence panel" where various sensors are contained. The automaker doesn't explain specifically what that means – presumably it will be some kind of cover since having a slathering of sensors exposed on the grille could get quite expensive in the event of a minor fender bender. But, BMW does specifically say it's a teaser for what will come on the production model.

In fact, much of what you see on this concept is either a subtle or not-so-subtle nod for what to expect on the future i4. The overall styling looks nearly production-ready, though the blue outline for the diffuse-styled faux exhaust outlets at the rear likely aren't production-bound. Similarly, the Interior probably won't be as airy and minimalist as what we see here, but keeping the i4 driver-focused is part of BMW's plan. The large, curved display is said to preview the brand's future displays for the invest as well as the i4, incorporating low-glare screens which negate the need for shrouds or housings to block outside light.

With electric cars, these benefits are largely negated. It's why some automakers are crafting distinct sounds for their future EVs to generate. In the case of BMW, it turned to one of the best composers in the business, famous film score composer Hans Zimmer, for a little help.

The Academy Award-winning composer worked with BMW sound designer Renzo Vitale to come up with a new sound which was previewed in the Concept i4 unveiled last week. The sleek, fastback sedan concept previews a battery-electric model to be called the i4 that's set for a debut in 2021. The car will fill in for the 4-Series Gran Coupe in the redesigned 4-Series family.

 “Renzo and I were inspired to bring together the past and future of BMW with the sound for the BMW Concept i4,” said Zimmer. “We hope the sound we created is classic yet surprising and has a feeling of lightness that is fitting for the BMWbrand.”

The sound will vary for the different driving modes that future BMW EVs will offer. Zimmer was also tapped to help craft sounds for when the car is started and when a door is opened.

BMW's next EV will be the X3-based iX3 due later this year, though we won't see this model in the United States. The iNext mid-size SUV will follow around mid-2021 and then the i4 toward the end of 2021.

 BMW hasn't said which of its future EVs will be the first to feature the new sounds.
