History of the Renault R312
A bus with a flat floor
The R312 succeeded the SC 10, originally a Saviem design of the 1960s, with a prototype completed in 1984 and production from 1987 to 1996. The 12-metre bus put its 9.8-litre six-cylinder Renault turbo-diesel behind the rear axle, which allowed the interior floor to be flat over the whole length of the vehicle. The engine was available with 152 kW (207 PS) or 187 kW (254 PS). It was primarily built as an integral bus, although some were completed as rolling chassis for other bodybuilders.

In service
The bus was popular in France, with over 4,000 produced and the RATP operating more than 1,500 during the 1990s. In Australia the Renault PR100.3 has the same visual appearance as the R312, and export sales went to Germany, Italy and Switzerland.

Renault R312 versions
