BMW recently announced plans to introduce two new concepts at the Pebble Beach Concours d'Elegance and a new report is indicating the mystery models will be an M4 GTS concept and an updated version of the 3.0 CSL Hommage concept.

Nothing is official but Autocar is reporting the M4 GTS concept will be a "thinly disguised" version on the production model which is slated to go on sale next year. The model is expected to be heavily influenced by the M4 MotoGP Safety Car so we can expect an aerodynamic body kit and an upgraded 3.0-liter TwinPower Turbo six-cylinder engine with a water injection system.  The latter change could enable the model to produce up to 467 bhp (348 kW).

Little is known about the updated version of the 3.0 CSL Hommage concept but speculation suggests its second showing could mean the company is considering a production variant.
