–          The turbo intercooler keeps charge pressure temperature within the allowed window

–          Turbo air inlet feeds the turbocharger with colder air , improving engine’s power output

–          MGU K (motor generator unit kinetic) harvests energy under braking and also provides a power boost of 160 bhp

–          Energy store batteries are now placed under the fuel cell , must weight between 20 and 25 kg.

–          MGU H (motor generator unit heat) harvests energy from the turbo turbine that can be both stored in batteries or used immediately by the MGU K

–          The central final exhaust pipe exits above the gearbox

–          The oil tank continues to be placed in front of the engine . Its shape and dimensions are dictated by engine’s needs and overall packaging

2014 Engine – Drivetrain regulation changes


     2014 is a season introducing the most extreme engine regulation changes seen for the last two decades . The new hybrid turbocharged engine types and drivetrain systems  are less dependant on fuel cinsumption, able to harvest and exploit larger amounts of wasted energy from gases and braking , but produce in total the same power output like the previous units. Furthermore are more compact  but with greater cooling needs, two opposite trends for car designers, the first allowing a reduced rear bodywork while the second enlarged cooling sidepod radiator inlet surfaces.

  The tables below summarize some key spots between the current and the former configuration
