The IAAPS’ highly specified climatic rolling roads, with instrumentation to research standards, enable evaluation and optimisation of complete vehicle performance in real-world driving conditions. Within our 250kW climatic control four-wheel drive rolling roads we can investigate vehicle emissions, efficiency and performance in real-world driving conditions. The chassis dynamometers can deliver environmental capabilities from -10°C to +40°C and are equipped with robot drivers which ensure maximum repeatability. These facilities encompass a soak area for vehicle stabilisation with capacity for up to nine vehicles. There are two thermal chambers which can drop down to -10°C to prepare vehicles for low temperature work. These cells are equipped with electrical power analysis and a full suite of highly capable conventional and FTIR emissions analysers.
