The Renault R312 is a class of buses produced by the bus division of Renault Trucks from 1987 to 1996. It succeeded the SC 10, which was originally a Saviem design from the 1960s.
The 12m long bus is rear-engined, powered by a 6-cylinder Renaultturbodiesel engine with a displacement of 9,834 cc available with either 152 kW (207 PS; 204 hp) or 187 kW (254 PS; 251 hp). By placing the engine in the rear, the interior was flat over the vehicle's whole length.
