Does anyone know whether or not the GMC RTS II Articulated Bus, model T9J204, would have been successful if it were to have materialized beyond the prototype phase?
Specifications did exist: the powertrain was a Detroit Diesel 6V92TA MUI engine producing 315 hp @ 2100 rpm (#2 diesel fuel) and Allison V735 transmission.
In Canada, though, a GM articulated bus did exist, but only for that market (and delivered to just four cities there, all in the province of Ontario: Mississauga; Ottawa; Hamilton and Toronto), only for the 1982 model year and just 53 units made. Essentially it had the GM Classic front end fused to the "New Look" body. The powertrain was a Detroit Diesel 8V71N engine producing 255 hp, mated to the Allison V735 transmission.
10 years later, MCI (which took over bus production from GMC in 1986) dusted off this model as the TC60102N, which now shared its entire body with the Classic and used the Detroit Diesel 6V92TA DDEC engine (making roughly over 300 hp) and Allison VR736 ATEC transmission, but again this wasn't anything to write home about: equally as short-lived, it was (as before) never ordered outside of Canada, and this time only being delivered in Quebec City, QC and Halifax, NS (the latter of which got most of these).
