The Sport Tourer comes with a choice of five gasoline and six diesel engines, including the new high-efficiency TCe 130 engine, developed by the Renault-Nissan alliance, which is a 1.4-liter engine 'that boasts the torque of a 2.0-liter engine and the power of a 1.8' with CO2 emissions 'less than those of a 1.6.'The New Grand Scénic is a seven-passenger MPV, and the New Scénic seats five. A choice of three gasoline and six diesel engines is offered on the Scénics.Both MPVs have a reversing camera with sensor and optional Carminat TomTom satellite navigation.
