Formula 1, made with more than 2200 pieces from the lego technic set Lamborghini Sian, 
it has suspension in all the 4 wheels 
-the rear wheels are connected with a differential to the motor through an 8 speeds working gearbox. 
-the shifter of the gearbox is behind the steering wheel just like in the real car and also works when you want to change the speeds.

And in the front wheels it has an anti-roll bar that works with the suspension, the positive angle caster, and the steering, so the anti-roll bar doesn’t affect the performance of the other 3 functions in the front wheels and also it has a nice green lime looking bodywork.
