Renault New Plug-in Hybrid Drivetrain for B Segment Vehicle

摘要

The world of hybrid drivetrain is changing.Electrification is obviously a needed asset in any Powertrain line-up to reduce CO_2emission and achieve CAFE compliance. If the choice of a car is only rational, in aworld where the choice of a car would be only rational, this could work. But to becomesustainable in our world, these electrified powertrains must respect customer expectationregarding driving pleasure, performances and, naturally, cost. In fact, they mustcreate customer desire.To take that challenge, Renault-Nissan Alliance has developed a new dedicated hybridtransmission for its bestselling models: New Clio E-TECH and New Captur E-TECHPlug-In. Confirming its versatile character, Renault Captur E-TECH plug-in will be aworld premiere among B-segment vehicles.Providing EV-like fun to drive has been a key goal for the development. To achievehigh responsiveness, vehicle take-off is operated in pure electric mode in any conditions.The new multi-mode DHT has been designed to be continually suited to the driver’srequest with optimum efficiency. Constraints on battery sizing due to vehicle architecturemade this efficiency as priority to achieve a real daily autonomy range. Right combinationof electric motors and ICE gives more dynamism during sharp acceleration.Development of the transmission was strongly focused on compact design to fit withB-segment vehicle and friction reduction to enhance drivetrain overall efficiency. A newgear shifting process is one of its key features.Renault-Nissan Alliance approach has been to implement EV engineering experienceand assets in this drivetrain designed for hybrid and plug-in hybrid vehicles.This presentation will give more light on specific features of E-TECH Plug-in. Renault-Nissan Alliance has taken benefit from its know-how in EV drivetrain design and tuningto provide the best EV experience in pure electric mode.
