Renault Rafale Atelier Alpine E-Tech 4x4 300 hp - new brutal powertrain
he combustion engine is combined with three electric motors (two main and one secondary) with a total output of 300 hp:
the main electric motor on the front axle, developing 50 kW (70 hp) and 205 Nm of torque
the second main electric motor, permanently connected to the rear axle, developing 100 kW (136 hp) and 195 Nm of torque
the secondary HSG (High-voltage Starter Generator) electric motor developing 25 kW (34 hp) and 50 Nm of torque.
For a dynamic driving experience, the engine and motors work together to unleash the full potential of the vehicle, with performance levels as follows:
0 to 100 km/h in 6.4 seconds (compared with 8.9 seconds for the 200 hp E-Tech hybrid)
80 to 120 km/h in 4.0 seconds (compared with 5.6 seconds for the 200 hp E-Tech hybrid)
1,000 metres from a standing start in 26.9 seconds
The two main motors are powered by a 22 kWh/400V lithium-ion battery for electric driving. The secondary HSG (High-voltage Starter Generator) electric motor starts the internal combustion engine, controls gear changes on the automatic gearbox and helps charge the battery.
Alongside the Esprit Alpine finish shared with the E-Tech hybrid 200 hp version, Rafale E-Tech 4x4 300 hp is available in a specific Atelier Alpine version. An evocative name that brings to mind the advanced expertise brought to Renault by Alpine Cars.
This pooling of talents makes it possible for drivers of Renault Rafale to enjoy “the Alpine experience”. Specifically, the Atelier Alpine chassis was tuned by a group of around a dozen dedicated engineers from Alpine Cars through the development of:
special parts: dampers, springs, jounce bumpers, front and rear anti-roll bars and 21-inch wheels;
a exclusive controlled damping system named active suspension with predictive camera;
specific Agility Control modes (see the paragraph on p. 5);
calibration of the ECUs controlling braking, regenerative braking, stability and trajectory control and power steering;
expert support in coupling the powertrain to the chassis and the Continental sports tyres.
Specific to Rafale Atelier Alpine version, a 'Chassis Control' menu on the multimedia screen lets drivers adjust the 4Control Advanced settings, the damping profile and the rear steering angles in three ways:
Comfort, for everyday journeys, particularly in the city.
Dynamic for a compromise between agility and filtering.
Sport, for handling and driving pleasure.
These agility control settings are available in all driving modes (Eco, Comfort, Sport and MySense) with the exception of Snow mode.
Reflecting the wide range of adjustable technologies available on the Atelier Alpine version (four engines, 4-wheel drive, 4-wheel steering, regenerative braking and active suspension), these three modes allow drivers to customize very easily Rafale to their own requirements.
