The next gen Golf will be equipped with a 48V mild hybrid system. A new 2.0L TDI will be the first VW turbo diesel with a mild hybrid system. Wayne Gerdes – CleanMPG – May 15, 2018 48-V belt-integrated starter generator, 48-V battery and DC/DC converter. Vienna, Austria – At a European drivetrain symposium, Volkswagen announced it will be updating its model lineup with completely new electrified drive systems. These include affordable mild hybrid drives with 48V technology and a new high-tech hybridized turbo diesel. One of the most important is a 48V mild hybrid system scheduled for the next generation Golf. With the new 48V system, VW aims to make hybrid drives more affordable. The drive systems reduce consumption and emissions. Volkswagen will gradually extend the electrification of conventional drives to the entire fleet. The next Golf represents the starting point in this worldwide electric campaign. The next drivetrain is one we may never see in the U.S. but it interests me anyway. The updated 2.0L TDI turbo diesel engine will have the moniker EA288 Evo. VWs turbo diesel will be ready for the future. In Vienna, VW demonstrates the great potential of this drivetrain. The EA288 Evo will begin as a mild hybrid drive with 12V belt starter generator. In conjunction with a Li-Ion battery, the mild hybrid system reduces fuel consumption. The brand promises the new TDI engine(s) will provide extremely low emissions in all driving cycles. The Evo 2.0L TDI output ranges from 136 hp to 204 hp. The TDI engines developed by Volkswagen will initially be used at Audi in vehicles with a longitudinally installed drive train. The new TDI engines will also be used transversely in the MQB designed vehicles in the future. With the EA288 Evo engine family, Volkswagen has developed a TDI that is technologically at the forefront. The combustion process has been redesigned to reduce both fuel consumption and emissions. The exhaust aftertreatment components include a reconfigured diesel particulate filter and SCR system. 48V technology 48V technology enables drives to be electrified more affordably. The 48V system via a belt-integrated starter generator (BSG) enables a considerably higher amount of energy to be saved with lower current than a 12V system while allowing some brake regeneration. Like Hyundai’s single motor systems with a BSG but not designed as a full hybrid, VWs starter-generator performs the role of alternator and starter. At the same time, it functions as a small, lightweight electric motor that immediately increases drive torque upon start-up by means of an electric boost. The power of the generator is transferred via a belt. The generator also starts the combustion engine which is switched off as much as possible while the vehicle is moving. Think of it as an electric FAS! The starter generator receives the necessary voltage via the 48V battery and the 12V power supply receives the required voltage via the “DC/DC converter”. The full electric and electrified drivetrain strategies will result in a product lines diverges into two branches. This new product strategy will arrive in 2019 with the launch of the next generation Golf and the first I.D. The big question is why not a full hybrid 300+ V drivetrain? Can it cost that much more?
