BMW will allegedly preview the next-generation 4-Series with the launch of a model dubbed the BMW Concept 4 Series at September’s Frankfurt Auto Show, BMW Blog reports.

The new 4-Series has been spied testing on multiple occasions in recent months and was expected to be unveiled before the end of the year. Instead, this report claims that it will be previewed by the Concept 4 Series ahead of a reveal sometime in 2020.

BMW is no stranger to previewing its forthcoming production models with concepts and did just that with the X7 in late 2017 thanks to the launch of the Concept X7 iPerformance. BMW also previewed the previous-generation 4-Series with a show car dubbed the BMW Concept 4 Series Coupe.

Limited details about the new concept are known but it is claimed that an enlarged front kidney grille will differentiate it from the 3-Series sedan. Depending on your tastes, this is either good news or bad news but it does promise to give the new 4-Series a unique look, something which can’t be said about the old model that looked virtually identical to its 3-Series sibling but with two fewer doors in coupe guise.

The production-ready 4-Series is expected to be sold in Coupe, Convertible, and Gran Coupe configurations that will receive various engine and transmission options from the latest 3-Series. Consequently, there will be a number of four- and six-cylinder turbocharged petrol and diesel engines on offer. A plug-in hybrid will also be available. The range will continue to be topped out by the M4, receiving the same redesigned 3.0-liter twin-turbocharged inline-six engine as the forthcoming M3 and currently used by the BMW X3 M and X4 M.

We have contacted BMW asking for more information about the Concept 4 Series and will update this story if and when we hear back.
