Today there are more and more heat exchangers located at the front end and vehicles are equipped with higher and higher power engine. In the next few years, front end design of vehicle will have to be deeply modified in accordance with the pedestrian crash test specifications. In this way there is a big packaging problem at the front end to solve. This new UltimateCooling™ system uses only one fluid that is water (coolant) to cool all of engine fluids. The conventional heat exchangers cooled by air become new heat exchangers cooled by water. These new heat exchangers: WCAC, WCDS, WOC and WFC will be moved from front end to under hood. At the front end there is only one multi-temperature radiator providing high temperature and low temperature on demand. Will be presented in this paper:
- Fuel consumption based on MVEG cycle under ambient temperature of 35 and 28 °C,
- Dynamic response of vehicle during acceleration of engine,
- And new coolant architecture of UltimateCooling™ based on CO2 as new refrigerant instead of the conventional refrigerant R134a.
