Dacia to Launch Unique Hybrid AWD System on Duster and Bigster, Featuring LPG Option
Dacia is preparing to introduce an all-wheel drive (AWD) hybrid powertrain option for both its Duster and Bigster SUV models, a system the automaker claims is unique in the current automotive market. The new drivetrain combines a gasoline engine with LPG capability and an electric motor, offering a novel approach to enhanced traction and efficiency.
The hybrid system centers around a 1.2-liter three-cylinder engine paired with a 48V starter-generator and a 23kW (31 hp) electric motor positioned above the rear axle. the combined system delivers a total output of 113kW (154 hp) and 230 Nm of torque. A key feature is the dual-fuel capability, with the vehicles equipped with two 50-liter tanks – one for gasoline and one for LPG – potentially providing a total range of approximately 1500 kilometers.
Dacia states that the vehicle can operate in electric mode for up to 60% of journeys. The rear-wheel drive system, powered by the electric motor, can be fully disconnected to conserve energy and re-engage automatically when front-wheel traction is compromised, optimizing performance in conditions like snow, mud, or sand.
The internal combustion engine is coupled with a six-speed dual-clutch automatic transmission with paddle shifters.The rear electric motor utilizes a two-stage gearbox, a unique solution designed to deliver high torque at low speeds for enhanced acceleration and braking, while also optimizing efficiency at higher speeds. Dacia confirms the electric motor can operate up to 140 km/h, though the overall vehicle top speed remains undisclosed.
Drivers can also manually control the electric motor via paddle shifters, providing added control in challenging terrain. The system also includes pre-selected off-road modes for various surfaces, automatically adjusting torque distribution to the wheel with the most grip. Importantly, the AWD system is entirely electronic, with no mechanical connection between the front and rear axles.
While final homologation is still underway, Dacia anticipates fuel consumption figures between 7.1 and 7.2 liters of LPG per 100 km, or 5.5 to 5.6 liters of gasoline per 100 km. Pricing details has not yet been released, but Dacia plans to launch the new AWD hybrid models by the end of the year.
