The MGU-H, which converts hot exhaust gases in to electric energy, has proven to be the most challenging element of F1's turbo hybrid power units since they arrived in 2014.
The headaches it has caused some manufacturers to get on top of the technology, allied to the costs of doing so, have led to several pushes to try to rid the sport of it for the long term.
