We’re still waiting for a new full-length Transformers: Dark of the Moon trailer but today, during the premiere NASCAR race – the Daytona 500 – Transformer fans were treated to another action packed TV trailer.

Half of the new Transformers: Dark of the Moon trailer is comprised of content from the Super Bowl trailer – but the other half offers a number of new shots including a better look at Optimus Prime, Starscream, the NASCAR Wreckers – as well as a hybrid vehicle/combat mode for Bumblebee.

Michael Bay has confirmed that Dark of the Moon will be his final Transformers film and, judging by the film footage we’ve seen so far, it’s apparent that the director certainly aims for the picture to be his most “epic” film yet. That said, each subsequent trailer continues to build on the already enormous buzz for the film, hinting at the possibility that this installment could also capture the highest box office grosses for the robots in disguise. As a result, it’s hard to imagine that Paramount is simply going to walk away from the franchise – once Bay moves on.

Despite the traditional “Starscream lands on the ground” and “Sam running for his life” shots, the new trailer offers a great look at Optimus Prime as well as an intriguing new detail – Bumblebee’s enhanced vehicle/combat hybrid mode. Recently, on our sister-site, Game Rant, we covered a new gameplay mechanic called “Stealth Force Mode” that will factor heavily into the upcoming Transformers: Dark of the Moon video game tie-in. Could “Stealth Force Mode” be a major new feature in the upcoming film as well (like combiners were in Revenge of the Fallen)?

According to the game’s press release, “Stealth Force Mode” is a “third, hybrid state that combines the weapons and firepower of robot mode with the agility and maneuverability of vehicle mode.”

Similarly, we’ve already seen Optimus Prime firing on enemies while in-flight (in the prior trailer) and his upcoming MechTech Ultimate figure refers to a “Battle Flight” hybrid mode. Whether or not the hybrid vehicle forms will actually be addressed with a story explanation in the film, or even referred to as Stealth Force Mode, is anyone’s guess – though it’s extremely likely that these hybrid forms will at least provide some of the cooler moments in the third Transformers movie.
