Before I blind bought my TCe180 (after doing a lot of research!) I would not even give Renault the time of dayYeah definitely agree.
Tbh, prior to look at the new design RS' I never thought about the previous models (I think what put me off now is that they're only three door rather than the new remodelled 5 door)
But definitely some absolute stunning RS' about no doubt about that
...after buying & owning Megane RS are the only car I would ever consider right now even if money was no object
Driving one is such a pleasure the steering is so light & precise, the engine offers massive torque for the low weight producing some stunning driving experiences
for UK roads they are perfect!PK4 gearbox in the TCe, GT, RS250-275 is capable of 400NM but without upgrading your intercooler & putting a hybrid turbo on it not sure its worth risking the reliability issues vs just buying a newer faster model

I am so torn between buying brand new RS 300 (long waiting list though!), used RS280-300 with low miles (most likely option) or slightly older circa 2015-16 RS mk3 Trophy. I love my current TCe 180 (exact same RS DNA same engine as RS250-265 range just lower turbo boost pressure & compression ratio so 40BHP & 60NM down but more comfortable ride due to the RS chassis designed for comfort instead of outright performance). Renault EU later rebranded the TCe range into TCe-RS or GT220-RS in EU on the badges & cockpit but in UK they just stayed branded as TCe or GT!).
A lot of drivers (without megane experience) do not understand that RS & Megane Coupes TCe & GT are a long way away from the other Renaults brands build quality & driving experience wise as different engines, chassis & more sporty overall design

Current Megane RS300 5 door range is perfect all rounder really as just enough space for the family & practical everyday driving yet sporty enough to keep the driver-owner very happy!
so its not possible as the charging circuit is built around this D.E.S.S item no way to change it (unless your Ocon the F1 driver in the video I linked to that is!!).
The frustrating thing with Renault they refuse to admit its a car design problem they say its driver error & dealer error for not maintaining the battery properly
no chance they fix it either as RS300 & RS300 Trophy-R are end of the line now (although another 2 years of factory assembly lines are already booked). The battery management is tied to the braking energy recovery system afaik! Changing would mean going through EU vehicle type approval all over again! France, Germany, UK are the biggest markets outside of those RS sell in very limited qualities so no way they go through the cost to change it now its close to end of life.
