Rotax has multiple patent's approved for a 2 stroke electric assist turbo system (many of these patents approved in late 2015 and early 16), not exactly sure of total configuration but understand patent's include a liquid cooled pipe (sounds strange ??) with in/out/empty check off valve configuration ECU controlled. Gear/electric motor turbo assist. ECU to control the turbo air flow rate and boost pressure as it will be in full control of the compressor speed, the pipe (liquid or not) will also be electronically monitored by the ECU which will match the direct inject fuel flow rate with the return speed of back pressure for a more complete intake, combustion, exhaust cycle. Due to the increase in energy produced from a turbo at higher RPM the excess energy will be used to recharge a energy capacitor (super capacitor as BRP calls it) so the next low/mid RPM acceleration request the super capacitor will power an auxiliary gear/motor attached to the turbo to assist in initial turbine speed via ECU. The SHOT start system is evidence that they have a working capacitor charging system, (patent 2015) so now the extra energy harvested from the turbo can charge both of these systems and most likely hold a longer charge with an increased/improved capacitor capacity. You never know, BRP has patented a lot of crazy/strange things that have never made it to production this could very well be one of them. That said the 850 (G4) is prime for a turbo, cooling capacity chassis and motor, larger water pump, the HD crank and crank cooling/oiling, direct inject, cylinder coating, pistons, rings, the ECU is 2X faster then the previous version, super capacitor for storing needed energy all add up as a strong possibility. Maybe next year, maybe 2021/2022,, maybe never but it did take the ACE 900 5 years to add boost to it! I'm going to watch BRP Lynx site as well as they released this msg via facebook on Feb 15th, 2018
"So the testing of our new 2019 Lynx models going great! We have some really exciting news for you all". Release date for Lynx is normally around March 20th, but I don't have the date, sorry.
