BMW has announced plans to stage the world premiere of two concepts at this year's edition of Pebble Beach.

The two concepts will serve as a celebration for BMW North America's 40th anniversary and based on this teaser image, certainly one of the cars will be a performance model. We assume these two concepts will provide a first glimpse at the M2 and the M4 GTS which are both expected to show up in production form before the end of the year.

We've been talking a great deal lately about the M2 which will have a turbo-six 3.0-liter with an estimated 370 PS (272 kW) and 465 Nm (500 Nm with overboost) sent to the rear wheels through a six-speed manual and/or seven-speed DCT. It should do the 0-62 mph (0-100 km/h) task in less than 4.5 seconds and top out at 170 mph (274 km/h) with the M Driver’s Package.

As for the M4 GTS, this will allegedly lose 100 kg (220 lbs) compared to the regular M4 and will come without a rear bench while a roll cage will be optionally available. It's bound to receive the water injection system sourced from the M4 MotoGP Safety Car which should boost output of the 6-cylinder TwinPower Turbo 3.0-liter engine to as much as 500 PS (368 kW). It could turn out to be a limited-run model and is expected to be offered in only three exterior colors.

BMW will reveal the concepts on August 13 during a preview press conference at BMW Villa in Pebble Beach.
