Under the radar, but LEGO revealed an update about replacing the ABS brick both in their 2016 Responsibility Report and a LEGO Batman Movie article here: The prototypes as featured in the Responsibility Report: So, what do you think of the progress? Mods: If this should be merged with a previous thread, please do so. I didn't want to bump a three-year-old topic.
This is my entry to the Rebrick BMW Motorrad competition. Its goal is to balance both performance and sustainability to show that high-performance vehicles have a future in a world concerned with emissions and fuel consumption. I used double wheels on both the front and rear in order to make this model driveable. The wheels are made from 36 chain links bent "the wrong way" - they are around 16cm (20 studs) in diameter. The whole model is about 55 studs long and 13 wide. The drivetrain consists of a PF Large motor geared 1:1 and a PF XL motor geared 5:3. They are hard coupled - yes, I know this is frowned upon but it provides a compact solution, and the load on the motors is no different to driving a car up a hill. The motors are mounted inside the rear wheels to save space and simplify the drivetrain. The motors are connected to an IR receiver which is mounted inside the main body. The battery pack is positioned at the very bottom to lower the center of gravity and increase stability. There is a shaft connecting a 4-cylinder piston engine to the wheels. This piston engine runs on E85 bioethanol which is derived from plants. This means it is renewable and carbon-neutral - the carbon dioxide released when burning it is compensated for by the plants used to make them photosynthesising. It also has a higher octane rating than gasoline, meaning it can actually provide better performance than the fuel it replaces. E85 biofuel engines already exist - all recent Koenigsegg vehicles are capable of running on both gasoline and E85, and these engines can produce up to 1 megawatt from a 5-litre V8. I believe biofuel is the future for high-performance vehicle manufacturers such as BMW. The front suspension uses a Duolever setup where the front fork is suspended on two parallel wishbones. The front wheel is able to move up and down and steer, while having the shock absorbers mounted on the wishbones rather than as part of the forks. A steering linkage allows a PF Medium motor to control the front wheel. The rear suspension uses a similar system called Paralever. It is essentially one half of a car independent suspension, complete with universal joints. It is sturdy and keeps the rear wheel's motion vertical when the suspension compresses. The front and rear wheel arches use the bucket wheel parts from 42055 as an internal structure. I used pneumatic hoses as part of the structure to give the flared appearance of the rear arch. greenshotcertificity.com Every part of the motorbike is designed with the BMW brand in mind (honest, it's nothing to do with the lack of turn signals ). The panelling (especially the side intake) is inspired by the BMW i8, a hybrid supercar by BMW. The suspension matches the types used on current BMW motorbikes, and inline-4 engines are commonly used on both their bikes and passenger cars. Here's a video showing the bike's drifting and burnout capabilities. Music is composed by me. Enjoy!
