Michael Bay has posted another snap of a car that will be featured in "Transformers 4". Surprisingly, the latest vehicle image reveals an upgraded look of Bumblebee, which previously has been introduced in vintage form of a 1967 Camaro. This time, the yellow autobot gets what Bay describes as "the final jewel in the 'Transformers 4' crown," a 2014 Concept Camaro.

The modern version of Bumblebee has recently been spotted on the filming location at a General Motors proving grounds facility in Michigan. From photos taken by Autoblog.com, the new Camaro hit the road along with the new Optimus Prime and Hound as well as a Bugatti Grand Sport Vitesse and a C7 Corvette Stingray for unspecified autobots.

The film's plot is kept secret but Bay gives hint to ComingSoon.net that there will be a "chase from hell" in the next "Transformers" film. Mark Wahlberg will be featured as a leading man alongside Irish actor Jack Reynor. Kelsey Grammer is on board the action-heavy movie, which is said to be "darker than its predecessors," to play a human villain.

Stanley Tucci, who will next be seen in "Percy Jackson: Sea of Monsters", is also included in the cast ensemble, which already has Nicola Peltz, Li Bingbing and T.J. Miller for supporting roles.

Penned by Ehren Kruger, "Transformers 4" will be unleashed into theaters nationwide on June 27, 2014.
