All parts of the power unit were made
lighter, more compact, and more efficient,
for improved packaging efficiency.
The result: the entire unit fits behind the rear seat.
Packaging efficiency of the IPU (Intelligent Power Unit) has been substantially improved, by integrating the PCU (Power Control Unit) and the IMA battery.
|
| The PCU's main components, the inverter and the pre-driver, have been integrated, reducing the unit's weight by about 30% and its size by about 40%. The IMA battery's modules have also been made more efficient to reduce energy loss, and its box and peripheral equipment made more compact, realizing an approximately 30% reduction in size. This lighter, more compact, and more efficient PCU and IMA battery have been combined into a single IPU (Intelligent Power Unit), allowing the two cooling circuits previously used to be combined into one. The overall volume of the power unit has been reduced by around 50%, allowing it to be stored behind the rear seat. As a result, the new Civic Hybrid offers all the trunk space that one would expect in a sedan. (The numeric values above are based on the conventional HONDA IMA System). |

High-efficiency packaging, with all the roomy comfort you expect in a Civic.
Locating the IPU behind the rear seat permits superior packaging that does not compromise interior spaciousness. Reduction of trunk space compared to the Civic Ferio has been kept to a minimum, resulting in a roomy 342-liter* compartment.
*As calculated by Honda, according to VDA formula.
