What you have to remember is that the 2016 StreetDecks and the 2018 StreetDecks are different buses. Wrightbus have done a lot of work on these buses between the two different batches, one has a Micro-Hybrid 2 system with stop/start engine and the other doesn't.
Micro-Hybrid 3 is now available, and again further development work has been carried out by Wrightbus in the last year to overcome the main issues with the last models. They also now offer a 6-cylinder version of the bus (currently only 4-cylinder).
