Behind the wheel of the All-new Dacia Sandero, Sandero Stepway and Logan : Dynamic performances without a price
Behind the wheel, the All-New Sandero, Sandero Stepway and Logan enjoy better handling, more precise steering, more efficient engines and improved acoustic comfort. True to the Dacia spirit, they offer easy and comfortable driving in all circumstances.
The new modular CMF platform of the All-New Sandero, Sandero Stepway and Logan enables three major improvements. The first is acoustic: with a lighter and stiffer cradle, front block and body structure, vibrations are reduced. The second concerns the ground connections: the widening of the tracks by 41 millimeters on the Sandero and 29 millimeters on the Sandero Stepway respectively improves handling and road behaviour. The last concerns passive and active safety, with the integration of the latest generation of driving driver-assistance systems (ADAS).
On the undercarriage side, new shock and spring settings enable the All-New Sandero, Sandero Stepway and Logan to turn flat without rolling. These settings offer real driving pleasure on twisty roads while preserving comfort.
The steering, now 100% electric, offers 36% less effort compared to the previous Sandero. In addition, it is equipped with variable assistance according to vehicle speed, offering both a precise feeling of the front axle, which ensures better handling on the highway, and ease of maneuvering when parking, for example.
All the engines available on the All-New Sandero, Sandero Stepway and Logan comply with the new Euro 6DFull standard. They are coupled with two new, lighter gearboxes incorporating the latest mechanical developments in terms of friction: a 6-speed manual gearbox and a CVT-type automatic.
On the manual gearbox, the gear ratios have been improved to maintain a satisfactory level of torque over the entire range of use. On the 6th gear, they have been extended to obtain improved fuel consumption on motorways.
In order to improve fuel consumption, the car's aerodynamics have been improved particularly on the body (leaking roof line and roof lowered by 10 mm) and under the chassis (under-chassis fairings and front controlled flaps). The air penetration coefficient (called SCx) has increased by 8 to 10%.
The engines, new gearboxes, aerodynamic improvements, friction reductions (brake, rolling and tires) and reduced power consumption (LED headlights, high-efficiency alternator) of the All-New Sandero, Sandero Stepway and Logan have reduced fuel consumption by at least 6%, while offering more pleasure and identical performance.
To ensure that the pleasure aboard the All-New Sandero, Sandero Stepway and Logan is shared by all occupants, special care has been taken with the acoustics and the treatment of aerodynamic noise. Thanks to the rigidity of the CMF platform, the transmission of solid vibrations into the cabin has been reduced, reducing hum by an average of 3 to 4 dB.
Airborne noise perceptible from the cabin has been reduced using ‘framed’ doors (eliminating cavities between the doors and the body) and redesigned mirrors with a seal at their base.
Vehicle insulation has been improved by increasing the absorbent surfaces in the engine compartment from 12% to 48% and by reducing acoustic leakage.
In the passenger compartment, for example, background noise has been reduced by 3 to 5 dB between 50 km/h and 130 km/h.
