According to BMW Blog, the second-generation 4 Series will be revealed in an online unveiling to be held "sometime in June", due to the coronavirus pandemic restricting public gatherings and travel.
According to leaked photos, the updated two-door coupe boasts an exterior design very similar to the Concept 4 that preceded it, including a large kidney grille that has inspired mixed reactions online.

When the grille made its first appearance on the Concept 4, Domagoj Dukec, design director for the BMW brand, said it was a "confident and classy take on this iconic feature" that provided "a look ahead to the expressive face of the 4 Series range".
The car also appears to boast sportier touches like aggressive front and rear vents to differentiate it from the 3 Series sedan, although spy shots suggest the 4 Series will feature a very similar interior to its 3 Series companion.

When it launches, the 4 Series is expected to come in three body shapes – coupe, Gran Coupe and convertible – and will share the same Cluster Architecture (CLAR) platform as the 3 Series.
It's likely BMW will offer the new 4 Series with a range of powertrains at launch, possibly including a plug-in hybrid option on top of the usual petrol and diesel variants.
Eventually, it's expected the 4 Series range will be expanded to include an all-electric variant based on the Concept i4 that debuted earlier this year.

Unveiled in a digital reveal in lieu of a planned Geneva Motor Show appearance, the near-production-ready i4 boasts a 0-100km/h time as low as 4.0 seconds, a 200km/h top speed, and a claimed (WLTP) maximum driving range between charges of 600km.
