The Rezvani maybe one luxurious tank, but still runs on typical rubber tyres. However, some Russians who take the word 'tank' seriously have modified a Bentley Continental GT into a premium tank with real tracks. Even better, it sounds brilliant, just like any Continental GT would.

But on our previous report about this beastly machine, the builders of the world's most luxurious tank faced a roadblock. Actually, there is quite a handful of problems, but one of them in particular is the lack of doors.

Well, that problem has now been solved.

In AcademeG's latest video upload, the Continental GT Ultratank gets a pair of working doors. To make it work, the guys had to trim the sheet metal to accommodate the tracks. It wasn't an easy feat as the doors aren't just sheets of metal but a shell that contains sound deadening materials, electricals, and leather.

With the Ultratank getting its latest modification, the Russian guys were able to showcase the car on a public display along with other notable cars. Of course, it got the attention of unknowing bystanders. How often would you see a tank with real tracks on a car show, right?

Now, we mentioned that the lack of doors is just one of the tank's many problems, right? One of the other problems is the tension on the treads, which makes them slide when making a sharp turn. It's an issue that's hard to turn a blind eye on, as returning the treads back to its position is hard work.

Other problems include the lack of brake pedals, which is kind of needed to attain the ultimate goal – to reach the 62 miles per hour mark. 

Watch the video on top of this page to see the Ultratank with doors in action. You can start around the eight-minute mark to see the actual process of adding the doors.
