Transformers: The Last Knight is currently filming and almost no specific plot details have ben revealed at this point. Returning director Michael Bay has managed to keep things mostly under wraps, aside from casting news that brings back human players both familiar and new. By now most people know which side of the fence they fall on when it comes to the Transformers movies and the cinematic "Bayhem" they offer - but at the least, this new Transformers installment is bringing plenty of slick vehicles to the big screen.
The previous entry in this blockbuster series, Transformers: Age of Extinction, was a soft reboot that managed to introduce Mark Wahlberg's Cade Yeager and a handful of Autobots and Decepticons not seen before. Many of these Transformers (old and new) will be returning - and Michael Bay has been happy enough to Tweet out a new look for one of the robotic heroes from the last film.
Bay posted an image of a black and red Mercedes-Benz AMG GTR (see below), which will apparently be the new look for Drift, the Autobot with the attitude of a Samurai (voiced by Ken Watanabe). In Age of Extinction, Drift took the form of a black and blue 2013 Bugatti Veyron 16.4 Grand Sport Vitesse and a Sikorsky S-97 Raider Helicopter. This newly-unveiled vehicle form doesn't give away much about what this character will be up to, but it will certainly have speed.

In Age of Extinction, the most notable elements of Drift were obviously his Samurai qualities, which had him speaking mostly in haiku (for whatever reason). He also took the role of acting leader in the absence of Optimus Prime, much to the chagrin of Bumblebee. There was an element not addressed in the film, but found in both the toy line and the video game Rise of the Dark Spark, which held true to the original comics, indicating that Drift is a former Decepticon. Whether or not that will be brought up in The Last Knight is unknown, but it could potentially add some layers to the character.
Those kinds of character additions could be helpful in setting up the Transformers cinematic universe that is being developed out of this film. With Bay once again claiming this is the last time he will be directing a Transformers film, having some sort of work done to distinguish these robotic characters would go a long way in trying to make inter-connected films work and hold onto the interest of audiences. Of course, it also could easily just serve as a some backstory material to be read about on the back of toy boxes (or seen put to use as a plot device in video games).
Transformers: The Last Knight opens in U.S. theaters on June 23, 2017, followed by the Bumblebee spin-off on June 8, 2018, and Transformers 6 on June 28, 2019.
