8880 Super Car

Meanwhile I got a 8880 car in my possession too. I was thinking for a long time which one to get from the many super cars. Although I like the others too, the 8880 is special because it is still made of studded bricks and it has many working parts. Finally I have managed to get one.

The car has so many interesting details that I rather do not spend much time on how it was built. As a short summary, Grandma was here and played with the kids so that I can devote my day to it. At the end I succeeded.

How does it work? First, it has double wishbone suspension on front and rear. On the image above the blue items are the front wishbones. All wheels are driven, universal joints carry the rotation between the wheels and the differentials. The car has three of those - above you can see the front one but there is one in the rear and one in the middle too. In contrast to real all-wheel-drive cars there is no self locking feature, wheels can spin easily. But an owner of a Lego car can live with that.

The above picture also shows the gears of the gearbox. It is more sophisticated than
classic Lego gearboxes: there are freely rotating gears on two axes and moving the lever will attach them to the axles through special transmission rings. This set has 4 forward gears and no reverse but it has a fully functional neutral state. The lever can be operated the same way as on real cars. On the picture below shows the lever in fourth gear.

The car sports all-wheel steering as well: rear wheels steer in the opposite direction and less than the front wheels. It requires a good amount of force, there is no power steering :)

At the end of the drive chain there is a V8 engine driven by a real chain. The amount of moving parts can be felt when we try to push the car - it is much harder than with the 8458 racer. Engine brake is also realistic - the selected gear influences it a lot besides the speed of the pistons.

  1. What the... In... Damn! That is a Calibra V8 Lego model. My brother has the real thing and it looks exactly like it. Unfortunately, mine doesn't though. Awesome stuff and thanks for sharing!
