During the 2018 Geneva Motor Show held on March, Hyundai has announced its plan to launch a new-generation of Mild Hybrid, Hybrid & Plug-in Hybrid models, following what Kia have done with the Sportage recently, and we have caught a test mule of the first greener version to come of the successful SUV, the Mild Hybrid.
After Kia announced its first Mild Hybrid model, the next model to add Mild Hybrid 48v technology will be the facelifted Hyundai Tucson. No more details has been revealed yet, but we can said according to the latest reports, that Hyundai will offer first a mild hybrid variant, which consists on a 2.0 CRDi diesel engine and a hybrid system with a 35 KW electric motor and a 48V lead carbon battery.
Kia’s mild-hybrid technology features a compact 0.46 kWh 48-volt lithium-ion battery and a new Mild-Hybrid Starter-Generator (MHSG). By electronically controlling the MHSG using the inverter, the system switches seamlessly between two modes: ‘motor’ and ‘generator’. Connected by a belt to the diesel engine’s crankshaft, under acceleration the MHSG provides up to 10kW of electric power assistance to the powertrain in ‘motor’ mode, reducing engine load and emissions. In ‘generator’ mode, the system harvests kinetic energy from the vehicle during in-gear deceleration and braking and uses the power to recharge the batteries.
In other words, the Tucson Mild Hybrid equipped with the 2.0 diesel mild hybrid system will deliver 200 hp, like using the current 2.0 diesel engine with a superior smooth and powerful driving and a fuel economy benefit of about 20% better than the average of the model.
