A realistic but fake V12 engine which works when the vehicle moves.
Openable and lockable doors.
When I had produced the vehicle, I tried to motorize it using a Lego Power Functions L motor which I already had. This way, I acheived to make some space to fit the motor at the front side. Although when I was building the vehicle, I had planned to insert the motor at the rear side, but then the idea of a smooth and well-covered back led me to produce a bumper at the rear. Later on, I bought 2 Lego Powered Up L Motors to make this car fully remote controlled. I already had a battery box and remote controller, so just simply bought the motors. I produced more space at the front of the vehicle to connect it directly to the steering.
After comparing the speed of this innovation with other lego technic sets I have, I concluded that the heaviness of the vehicle slows down the speed and may result in increased batteries power consumption.
To make the car look better and even more realistic, I added lights to it. So to implement this, I used Arduino UNO starter kit set. I firstly produced the circuit, typed the code, and then finally compiled the code into the Arduino UNO chip. Fortunately, some lego parts are capable to hold the LEDs inside them, so this simplified my task for mounting the lights. I have made the 2 front white lights, 2 front indicator lights, and 2 red back lights. The back lights are capable to keep swtiched on continiously, and and it can also blink with the front indicator lights.
In dark, opening the lights make the car realistic, and in the treadmill experiment, this made a very realistic effect just as if a car running on the highway. The use of arduino is much better than using the Lego LEDs, as Lego products are costy and also have a higher consumption and many limitations, while in arduino, we can do anything we want with the LEDs and even use different color LEDs which is very cheap and full of variety.
I tested my vehicle on the treadmill by tying it with the treadmill. This way, I made several experiments and had fun driving the vehicle on the treadmill. The car easily reached the top speed of the treadmill, in my case 18 kmph.
I learned that when a vehicle is travelling at a fast speed, turning a little bit of the steering can turn the vehicle easily and more than in slow speed. Unfortunately, as the vehicle was heavy, the vehicle got the main, most occupied, pressurized, and important rod completely damaged that it had to be forcefully pulled out in order to replace it. Such was the damage that the socket in which the rod was inserted in needed to be replaced in order to work! Fortunately, I had got to know this early when I was trying to motorize it, as the 2 main gears within the vehicle were sliding on each other. Also, I have several rods of the same type in my other lego sets, so I can still make the actual set.
